PREFACE 

THIS work has been prepared to enable the reader to identity not only 
the Trees and Shrubby Plants <>t' the British Isles, but also the more 
common cultivated Trees and Shrubs, and of presenting in a concise 
form much valuable information on such subjects as Timber and its uses, 
Insect and Fungoid Pests, the more common Galls, the native habitat, the date 
of introduction to this country, methods of propagation, &c. \c Over 550 
species of Trees and Shrubs are described under the headings of Flowers, 
Inflorescence, Fruit, Foliage, Mode of Growth and Winter Buds, each plant 
under iK natural order, and the characteristics of the Order preceding each 
group. 

Although there have been many works produced dealing with Trees, we 

know of none giving detailed descriptions of SUCh a number of species, and 

the Shrubs, it is believed, have never been so dealt with. Many readers 
are well informed as to most of the herbaceous plants so often described 

in popular hooks, yet the) have little or no knowledge of the great majority 
of the Trees and Shrubs which specially help to make this country so beautiful 
It is the Authors' hope that their work will not onl\ enable such persons to 
identify all the sp eies common to these Islands, and many that have been 
introduced, hut will make them familiar with their Habitat, Form, Structure, 
Beauty, I Ises, Sue. 

The work appeals to Art Masters, Botanists, Field Naturalists. Foresters, 

the general reader who wishes to know something of Trees and Shruhs. 

Horticulturists. Natural History and Scientific Societies, Owners of Estates and 
Gardens, Students. Teachers, and to the users of General Reference Libraries. 

'The Authors' wide experience as practical botanists and field naturalists 

has been brought to hear on the subject, and where this has been inadequate, 

most careful research has lie, rj carried out. and no effort spared to make the 
work absolutely reliable and up to date. 'The style of treatment is scientific 
in so far as accuracy of detail is concerned, and whilst technical words have 



PREFACE 

been employed where necessary, there is a detailed Glossary of over .'{50 
Botanical terms with derivations of all words used, as well as lists of Latin 
and Greek roots used in Floral nomenclature, and Latin, English, Natural 
Order, and Colour Indices. 

The text is almost wholly the work of Mr. C. S. Cooper, Mr. W. Percival 
Westell, in the capacity of General Editor, having collaborated and been 
responsible for seeing the work through the press. 

The Authors wish to record their great indebtedness to Mr. George Paul, 
.1.1'.. V.M.H., of Cheshnnt, and his staff, who have at all times placed their 
valuable and unique experience at disposal and also enabled many points of a 
difficult nature to be settled from direct observation of the living plants. They 
are also under an obligation to Mr. II. R. Hutchinson, who, in his official 
capacity of Librarian to the Royal Horticultural Society, has always treated 
them with unfailing courtesy; and they desire to acknowledge the help accorded 
in the preparation of the Useful Insects plate by Mr. A. E. Gibbs, F.L.S., 
F.E.S. ; and by Mr. Claude Morley, F.E.S., who kindly supplied specimens of 
Insects; also the valuable assistance accorded by Mr. Wm. Dallimore, of 
the Royal Gardens, Kew, in the compilation of those parts of the Calendar 
dealing with the Conifera?. 

The works of many of the greatest authorities have been rigidly and per- 
sistently consulted, and the titles of some of the most useful of these are given 
at the end of the second volume for the benefit of those who may desire 
more extended information. 

The fine series of illustrations have all been specially drawn for this work 
direct from Nature by Mr. C. F. Newall, and the Artist has spared no pains 
to make his pictures thoroughly l-epresentative, and every detail technically 
correct. He is himself an experienced Botanist and an Artist of no mean 
calibre— a rare combination of great value in the accurate production of illus- 
trative work of this kind.

THE SCOPE OF THIS WORK 

In the present volume it has been the intention of the authors to provide 
some help to the Nature-student and others in the identification of not only 
the British trees and shrubby plants, but also of the more common culti- 
vated trees and shrubs. This branch of Botany has been sadly neglected 
in the past, with the result that although the young student, and even 
those of an older growth, may be familiar with most of the native herba- 
ceous plants, so ably described in the many popular books on wild flowers, 
there is a want of familiarity with the great majority of the trees and flower- 
ing shrubs which one may see in our public and private parks and gardens. 

Not only does this remark apply to the inquiring student, but it is 
astonishing how many so-called gardeners and owners of beautiful gardens 
are unfamiliar with the names and uses of many of the botanical treasures 
which lie at their very feet. Many such will be well informed as to the 
newest and latest varieties of herbaceous plants, but at the same time quite 
unable to say whether a certain tree in the garden is a Deodar or an 
Atlantic Cedar, a Wellingtonia or a Lawson's Cypress. Such at least has 

been the experience of the authors. Or again, how many could identify 

i b 



INTRODUCTION 

the Tree of Heaven (Ailantus), the Kidney-bean Tree (Wistaria), Tulip Tree, 
or Evergreen Oak? Yet these are by no means uncommon even in our 
thickly populated towns. 

Naturally all trees appeal to us most strongly when in leaf, but to those who 
will observe, many are the beauties to be found in the leafless tree, and much 
can be done to identify them by their bark, buds, and manner of growth. 

The botanist will of course examine the flowers, but possibly even in 
these days of enlightenment it does not always occur to the unscientific 
that even Oaks and Elms, and all our forest trees, are in their turn laden 
with floral treasures which will well repay close study. 

It has been our endeavour, therefore, to collect together from our personal 
observation and other sources, and present in a condensed form, much valu- 
able information which it is hoped will interest the young student, and lead 
him to ask the why and wherefore of those many facts which he may 
observe around him. 

Our attention is here confined for the most part to the species of hardy 
trees and shrubs which we may find growing either as indigenous plants 
in their natural surroundings, or under cultivation in the modern garden 
of any pretension. The number of hardy trees and shrubs enumerated as 
growing in the Royal Botanic Gardens, Kew, amounts to about 4500, and 
the Conifers reach a total of 700. Of this vast number we have endea- 
voured to mention all our native trees and shrubby plants, and most of 
the more commonly cultivated species. Very few varieties are described 
as their number is an ever - increasing quantity, and often the minor dis- 
tinctions are of but little interest to the serious student, who in such a 
vast subject must be content to work on broad lines. The Kew Hand- 
list gives the names of fifty slight forms of Berbcris vulgaris, which by 
some might be considered as distinct species. The plan of the work is 
rather of the nature of a scientific flora than a popular treatise, but it may 
be worth while to offer the student some suggestions as to how he may 
best utilise the information presented in these pages. The Latin names 
used are those of the Kew Hand-lists. In a few cases it has been found 



INTRODUCTION 

advisable to give one or more synonyms, especially when these are in 
common use among horticulturists, but the choice is a matter of great diffi- 
culty, as may be judged when it is remembered that the Hand-list often 
gives ten to fifteen to a species, and as an extreme case we find twenty-four 
allotted to Spircea canescens. The difficulty is especially felt when dealing 
with the Conifers, for many of these have been at different times described 
under the generic names of Abies (Firs), Picea (Spruces), and Pinus (Pines). 
In the case of certain genera which contain several cultivated species 
we have added a few simple cultural directions as to propagation. These 
will be found under the first specimen described, and, unless otherwise 
stated, may be taken broadly to apply to the species generally. 



INFLUENCE OF SOIL UPON TREES 

Having introduced our plant by its popular and scientific names, we 
point out its habits, and much may be learned as to which trees and 
shrubs thrive best in particular soils. Such is the constitution of plants 
that while some must be supplied with soil rich in organic material, some 
few others will make larger bushes and blossom with greater profusion in 
soil which the horticulturist would describe as poor. The Birch, Holly, 
Mountain Ash, and Scots Fir are found wild on the poorest of sandy soils. 

The Maple and Wild Service Tree will thrive in dry situations, whilst 
Willows, Alders, and Poplars will succeed best when near water. 

The Elder, Privet, Colchican Bladder Nut, and many others grow best 
in a moist loamy soil, and the Oak thrives on clay, whilst such as the 
Furze, Tutsan, Bladder Senna, Stone Pine, and Evergreen Cypress prefer 
a sandy soil. Rhododendrons, Azaleas, Kalmias, Ericas, and others of the 
same family require rich soil, readily permeable to moisture, sandy peat 
or heath-mould being the best, but a rich sandy loam mixed with leaf- 
mould and rotten turf will also answer well. Whilst the Heath family 
refuse to grow in soil permeated by lime, the Beech and Yew will flourish 

and do well, and the native flora of our chalk districts includes such 

iii b 2 



INTRODUCTION 

well-known trees as the White Ream, Wayfaring Tree, Box, and Purging 

Buckthorn. 

The list of flowering shrubs, deciduous trees, and conifers which may 
be planted on a chalk soil is a long one indeed, and many of these will 
flourish where the layer of soil resting on the chalk is often not more 
than six inches deep. 

INFLUENCE OF TREES UPON SOIL 

We have written at some length as to the influence of soil upon the 
growth of trees, but we may also note that the converse of this is true, 
namely, that trees largely influence the composition of soils in providing 
that humus which is so necessary for vegetable growth. It has been 
estimated "that after a sandy soil in New England is so exhausted that 
it will produce nothing but red mosses, it may be renewed to its pristine 
vigour and productiveness by the growth of trees on it for thirty years." 

METHODS OF ROOTING 

Trees and shrubs vary considerably in their method of rooting, for while 
the Ash, Birch, Cedar of Lebanon, Horse Chestnut, Oak, and Plane are 
inclined to root deeply, others, as the Beech, Elm, Lime, and Sycamore, often 
ramify so near to the surface as to kill plants growing near them, and 
frequently make it difficult or impossible for even grass to grow beneath 
their shade. 

SITUATION AND ITS INFLUENCE 

Not only does the soil decide the fate of trees and shrubs, but the 

question of sunshine or shade, exposure or shelter, are important factors 

in their life-history. Many will thrive best when able to bask in sunshine, 

as the Satin Flower and Golden Bell, while others delight in shade, as 

the Tutsan and Large-flowered St. John's Wort. 

Many evergreens will do well under the shade of trees, among them

INTRODUCTION 

being Box, Yew, Cherry Laurel, Portugal Laurel, Butchers Broom, and 
Holly-leaved Barberry. 

The outdoor student will probably have but little to do with the roots 
of trees, though many interesting questions are connected with their functions. 
Above ground, however, he has much to interest him and help him in the 
identification of the species at all seasons. 

SHAPES OF TREES 

Viewed from a distance most of our trees will be found to have a more 
or less distinctive shape, and much can be done to take this as a rough 
identification mark, but the peculiar characteristics of each tree are most 
apparent in late autumn and winter when the leaves are fallen and the 
different modes of branching are laid bare. In the Oak, with its expansive 
spread and large rounded head, we then notice the stoutness of its limbs, 
which, continually subdividing at right angles, twist here and there horizontally 
in various contortions, at once adding the idea of great strength to that of 
beauty. On the other hand, the Ash, with its easy-flowing lines and loose 
pendent branches, rather suggests the idea of beauty and elegance. Compare 
again the massive form of the Elms with the light gracefulness of the Silver 
Birch, and the tall spire-like column of the Lombardy Poplar, or the elon- 
gated pyramidal growth of the Deodar, with the broadly pyramidal head or 
flattened top of the Cedar of Lebanon. In their general conical outline, how 
well are many of the Conifers adapted for bearing the masses of snow in their 
native climes. 

IMPORTANCE OF STUDYING THE SPRAY 

To obtain a more accurate idea of the nice peculiarities and distinctions 
of trees we must examine their smaller parts with more precision, and a study 
of the spray is an interesting one for the winter months. We shall see that 
the mode of growth in the spray corresponds with that of the larger branches. 
In the Oak it breaks out in right angles, or nearly so, in a series of long and 
short shoots, giving that abrupt mode of ramification for which the Oak 



INTRODUCTION 

is remarkable, and generally springing from the upper side, running in such 
directions as to give the branches a horizontal appearance. The spray of the 
Ash runs in a scries of irregular parallels, the shoots springing out in opposite 
pairs, often only one coining to maturity, and that usually on the under side, 
so as to form elegant pendent houghs. In the Elm we find spray forming a 
series of acute angles with the parent branch, being given off" on alternate 
sides, often becoming pendent with age. The Beech exhibits the same kind 
of altcrnacy, but the acute angles are smaller, the distance between the twigs 
is wider, and the whole runs a kind of zigzag course, becoming pendent, but 
twisted and entangled. The subject may be pursued in other trees, but 
enough has been said to show that much may be learned towards recognising 
the species even in the leafless stage. 

MAIN STEM OR TRUNK 

The main stem or trunk of the tree is also in many instances peculiarly 
characteristic, as we may see in the leaden-grey, smooth trunk of the Beech, 
the peculiarly twisted stem of the Sweet Chestnut, or the rough, red-brown 
trunk of the Scots Fir, so frequently bent over near the top and denuded of 
its lower branches. 

THE BARK AND ITS USES 

The bark also serves very largely as a distinguishing mark, as in the 
thick, deeply furrowed, corky bark of the Oak, the shallower grooves in the 
Ash, the silvery-white peeling layers of the Birch, or the flaking plates of 
the Planes. The outer bark of trees is usually dead and dry, and in many 
cases is corky, giving a rugged appearance to the stem, as in the Elm and 
Oak, whilst in others it is capable of great distension, and presents a smooth 
appearance, as in the Beech. It is a protective tissue, acting as a buffer to 
the soft delicate structures that lie beneath, and one of its chief uses is to 
prevent excessive evaporation of the cell sap. 

In the bark of stem and branches we may often observe small transpira- 
tion pores known as lenticels. They assume characteristic forms according to 

vi 



INTRODUCTION 

the species, and are well seen in Elder, Beech, and Birch, in the latter being 
conspicuous as narrow slits measuring from a half to four inches in length. 

The bark of many deciduous trees and shrubs is brightly coloured, and 
advantage is often taken of this in planting for winter effect. 

Several of the Dogwoods have red stems, and browns are common among 
the Spiraeas and Syringas {Philadelphus). White is familiar in Silver Birch 
and the White-stemmed Bramble, greens in the Kerrias, Genistas, and Brooms, 
while in the Willows we have all shades of orange, yellow, and purple. 

The bark of many trees is subject to the attacks of Scale insects, Aphides, 
and various species of Bark Beetles, some of which are mentioned in the 
detailed descriptions, while the leaves of trees and shrubs are also largely 
eaten by various kinds of larvae. Man utilises the bark of the Cork Oak in 
many ways, and that of Oak and Birch is much used in tanning, though 
fast being superseded in this country by chemicals. 

The valuable alkaloid quinine is obtained from the bark of several species 
of Cinchona, and the popular Cascara Sagrada or Sacred Bark comes from 
the Rhamnus PursMana, a small tree closely allied to the English Buck- 
thorn, and found in abundance in the United States of America. 

USES OF TIMBER AND TREES GENERALLY 

Before leaving the main stem of the tree we may refer to the innumerable 

uses to which the timber is applied. The mere mention of only the principal 

would occupy several pages, and the ever-increasing demand being made on 

the world's forests by the advance of civilisation is becoming a serious problem. 

It has been said that forests have a remarkable influence on climate, especially 

as regards the rainfall, that forests check evaporation, and, by cooling the 

air above them, act as condensers of the aqueous vapour, causing the minute 

particles to unite and form drops which fall through the action of gravity. 

But recent research tends to prove this to be somewhat exaggerated, though 

over forests the rainfall may be slightly greater than in the open. In 

many districts, where the land has been cleared of trees, a diminution in 

the rainfall has occurred. The presence of trees tends directly to keep up and

render more uniform the water supply, by reducing the mechanical force of 
very heavy rain, and by means of their roots and the accumulation of humus 
retarding the passage of water through the soil. 



PLEA FOR AN ARBOR DAY AND RE-AFFORESTATION 

This state of things can be remedied only by scientific methods of re- 
planting, and in India and many parts of Europe a great deal is done to 
replace the timber-trees which have been cut down, while in Canada and 
the U.S.A. the younger generation are encouraged to plant trees on 
Arbor Day, a day set apart in each year for that purpose. That an Arbor 
Day will soon be instituted in this country is our earnest wish, for there can 
surely be no better or more commendable manner of commemorating any 
event than by planting a tree. Some barren spot will, as a consequence, be 
made brighter, some neighbourhood will become healthier, some poor mortal 
may perchance shelter under its welcome shade, some bird build its mossy 
cradle among its pliant branches. 

A land without trees is as hopeless, and as barren, as a well without water ! 

The very thought is sufficient to send a shudder through the frame of any 

man or woman worthy of the name, and in view of the continual outcry 

that we are hearing as to the means to be adopted for bringing people back 

to the land, here is one of the most cogent answers to the appeal. Dr. John 

Nisbet, in his revised edition of " Our Forests and Woodlands," gives a resumi 

of the progress of British Forestry since the first edition of the book appeared 

some seven years ago, and the important question of State afforestation is 

treated of briefly but with telling effect in view of our present enormous 

imports of hewn timber for pit-wood and of wood pulp for paper-making. 

We imported over two and a half million loads of pit-wood and more than half- 

a-million tons of wood pulp in 1907 ; and if our waste lands and poor pastures 

can be afforested with profit at all, it is precisely this class of coniferous 

timber that could be grown on them, and it would take thirty million acres 

of well-managed woodlands to simply supply these, our present imports.

INTRODUCTION 

While a great deal more might be done by judicious husbandry in utilising 
waste lands and making desolate places beautiful, affording work" for those 
willing to till the soil, and generally encouraging a love for the country, 
fortunately the tendency seems to be in the right direction. 



THE ADVENT OF THE GARDEN CITY 

The Garden City, for instance, has come to stay. It is the beginning of 
a new era. It is as yet neither Paradise nor Utopia, but it is a start on 
the road to better housing, healthier conditions for the people, more social 
intercourse, a love for the country, gardening, outdoor recreation, pursuits, 
and pleasures. " And what," you may ask, " has the advent of Garden 
Cities to do with trees?" The answer is obvious, for, if a Garden City 
is to be worthy of the name, trees and shrubs must of necessity play 
an important part in its upbuilding, its charm, its attractions, and its 
welfare. 

In more than one Garden City of our acquaintance we have been pleased 
to observe that tree planting is one of the chief and essential features that 
attract attention. Not long since we paid an interesting visit to a certain 
locality — now a Garden City — where there previously existed a six square 
mile area of pastoral country, sparsely wooded for the most part, excepting 
for two or three choice spots, prominent among them being a delightful 
common of seventy-eight acres, covered with Privet, Buckthorn, Blackthorn, 
Whitethorn, Elder, Wild Rose, and other trees, shrubs, and herbaceous 
plants. Now as the city develops the streets are being planted with many 
kinds of trees ; the common and its wild beauty is being rigorously pre- 
served ; the fostering of a natural inclination for gardening, hedgerows, trees, 
everything that is not an eyesore, is encouraged. It is, so far as has been 
possible in the short time at command, a Garden City in the truest sense 
of the word, and although we of to-day may not appreciate it as we should 
do, nor live to see its complete accomplishment, there are generations as 

yet unborn who will, we venture to predict, be thankful a thousand times 

ix 



INTRODUCTION 

that there was created for them a place of quiet beauty and restfulness, a 
city with pure air, blue sky, green grass, soaring larks, verdant trees, where 
they might find solace, comfort, and recreation far from the busy turmoil 
of the great City and the rush of the work-a-day world. 



STUDY OF WINTER BUDS 

The study of winter buds is a subject of great interest, and they are so 
definite and constant in their character that trees can be easily identified by 
this means. The twigs usually bear a terminal bud at the end, and others, 
known as axillary buds, arranged along the sides in a definite order. In the 
Ash, Horse Chestnut, and Sycamore they are in opposite pairs at right 
angles to each other up the stem. 

Then again in the Beech, Elm, and Plane we find them arranged more 
or less alternately, and we have a spiral arrangement in the Poplar and 
Oak. In the latter we also find a terminal cluster of five or six buds in- 
stead of the large solitary bud usually seen in that position. 

The young leaves within the bud are usually protected by bud scales, 
varying in number from a few to very many, as in the Oak, where we find 
twenty or more pairs of scales before a leaf is seen. The outer scales are 
often leathery, and may be either covered with hairs, or with a resinous 
secretion, so familiar in the buds of the Horse Chestnut. These are all 
means for keeping out damp and moisture, and for moderating the changes 
of temperature within, where any sudden freezing or thawing might rupture 
the delicate tissues. When the bud-scales die they leave rings of scars, and 
the distance between each set of rings represents a year's growth, so that 
it is easy to tell the age of a twig by counting these intervals. The fallen 
leaves also give characteristic scars, differing very much according to the 
species, but this is well seen in the Horse Chestnut, where they have the 
likeness of a horse-shoe, the resemblance to the nails being conspicuous in 
the ends of the fibro-vascular bundles of the leaf. 

The bud-scales vary much in colour, reds, browns, and greens being most

INTRODUCTION 

common, whilst in the Ash they are of so dark a shade of olive-green as 
to appear almost black in the distance. 



INSECT PESTS 

The timber of trees in the living state is subject to attack from insect 
larva?, two of the most common being those of the Goat Moth (Cossus ligni- 
perda) and the Wood Leopard Moth (Zeuzera cesculi). The former is most 
frequently associated with Willows, but is also partial to Oak, Lime, and 
fruit trees, especially Apple, Pear, and Plum. The latter attacks Ash, Beech, 
Birch, Elm, Walnut, and the before-mentioned fruit trees. 

The larvae of Wood Wasps, especially the Giant Sirex (Sirex gigas), often 
bore into the Fir trees, and those of many beetles work havoc in the wood 
of other trees. 



FUNGOID PESTS 

Among fungoid diseases which affect decay in timber, two of the best 
known are the Canker Fungus {Nectria ditissima), which is common in Apple 
trees, but also attacks Pear, Plum, Oak, Beech, Ash, &c, and the Larch 
disease or Larch Canker, which probably owes its origin to the spores of 
Peziza Wilkommii. 



AGE OF TREES 

In spite of their many enemies trees often attain great age, and though 
it is impossible to accept the estimates that have been made by the older 
naturalists, there is little doubt that individuals have remained in a flourishing 
condition for over a thousand years. 

Tradition places the age of some of the Cedars of Lebanon at about 
3000 years, and probably the Yew has attained as great an age. The speci- 
mens at Fountains Abbey are believed to have been flourishing twelve cen- 

xi 



INTRODUCTION 

turies ago, and Lime trees near Friburg have existed as long. Oaks, too, are 
long-lived, and several in England have probably stood for 800 to 1500 years. 
Space will not permit ns to pursue the subject further, but among others of 
the longest-lived may be mentioned the Cypress, Larch, and Elm, whilst the 
Wellingtonias and other giants of Western America carry us back in ima- 
gination beyond the dawn of history. 



NATURES LABORATORY AND COAL 

We have spoken of the uses to which we put trees in the present age of 
high civilisation. Rut what shall we say of those vast primeval forests which 
m the course of bygone ages were annihilated, and in the hidden recesses of 
Nature's laboratory transmuted into what we now know as coal? We can 
scarcely imagine what would be the industrial conditions of to-day without 
our seemingly inexhaustible supplies of this universal commodity, and the 
innumerable by-products which man in his ingenuity extracts from it. Yet 
what do we know of its origin ? Truly little indeed, and even that little 
only through the patient toiling of the geologist and botanist, who have 
combined to probe Nature's secrets and build up for us a feeble picture of 
the luxuriant vegetation which clothed these antediluvian wilds in those days 
which we call the Carboniferous Period. By patient research these workers 
have pieced together the story, and they tell us that among the largest 
forms which composed those forests were certain Lycopodiums or Club-mosses 
known as Sigillaria± and Lepidodendra. 

The Sigillariae attained a height of 60 to 70 ft., the unbranched stem having 
a number of longitudinal rows of diamond-shaped leaf-scars, and being some- 
what hollow, so that where the trees have fallen and been subjected to great 
compression, the fossil remains are simply the thickness of the double bark, 
that is, the two opposite sides of the envelope which covered the trunk when 
living. 

The Lepidodendra had much-branched stems, 100 ft. or more in length, 

also beautifully marked with scars, whilst the branches bore at their ex-

INTRODUCTION 

tremities cylindrical sporangia filled with minute spores. The bituminous coal 
in many instances is made up almost entirely of these spores and spore-cases. 

Another important group of trees which reached their maximum in the 
Carboniferous Period were the Conifers, represented to-day by our Firs and 
Pines. Those found in the coal-beds were closely related to the Araucarias, 
and in many districts their fossil fruits have been found in great quantities. 

There were also at this time lofty trees or bushes with multipinnate 
leaves several feet in length, in the shade of which other smaller species 
grew and flourished. 

Through the eons life and death marched hand in hand, and the accumu- 
lations of vegetable material, caused by the steady yearly shedding of leaves, 
fronds, and spores, and the decay of fallen giants, continued to grow, being 
subjected to an ever-increasing pressure, and gradually being covered by 
sedimentary deposits, beneath which they might remain till the genius of 
man should extract them from the depths of the earth to serve the wants of 
industry and his own dwelling. 

LEAF STRUCTURE, FORM, AND FUNCTIONS 

We have referred to the more aesthetic beauty of trees as exemplified in 
their general outline and ramification, but it is probably the foliage, with its 
ever-varying form and colours, and its niceties of light and shade, which will 
appeal most to the casual observer. 

We cannot here enter into a systematic description of the various forms 
of leaves, but it is a matter of vital importance in the identification of 
species, and, owing to the fact that the life of the flowers is at most a short 
one, it is often our chief guide. 

Not only do leaves vary greatly in their arrangement on the stem and 

in their outline, but they exhibit many minute differences in colour and 

texture, each with its own appellation, and for the meaning of these the 

student must be referred to the Glossary. This infinite variety of leaf form 

and structure is intimately connected with the environment of the plant. 

The deep incisions and clefts which give such beauty to the outline of 

xiii C 



INTRODUCTION 

compound leaves, and the disposition of the leaves on the stem, and of the 
leaflets on the petiole, are definitely related with the admission of light, 
without which the activity of the green tissues would be much impaired, 
if not altogether arrested. The texture of leaves is associated with the pre- 
vention of excessive exhalation and the consequent danger from heat, and 
among the devices adopted to shield the epidermis from the direct rays of 
the sun, and reduce transpiration, may be mentioned the coriaceous membranes 
with which many leaves are provided, the woolly or siliceous hair-like 
structures which are especially prevalent on their under-surfaces, and the 
revolute margins of many which grow in exposed situations. 

Among the contrivances adopted as a protection against animate nature 
may be mentioned the various forms of stinging hairs, spines, and prickles to 
be found on the leaves, petioles, stems, and branches of various plants. In 
the struggle for existence, and in the face of the incessant depredations of 
animal visitors, these modifications of plant structures have undoubtedly 
been the salvation of the race. In the case of the lower forms of animal 
life, more especially as regards the insect world, the signs of warfare are 
many and numerous, whole colonies of trees and shrubs sometimes being 
denuded of foliage by insect larvae, and volumes have been devoted to the 
description of the various galls which owe their origin to insect agency. 
Many of these attack the leaves, and attention is drawn to a few in the 
descriptive pages. The foliage also is especially susceptible to fungoid diseases, 
and an interesting study may be made of these at all seasons of the year. 
The life-history of many is at present but imperfectly known, and a wide 
field of research here lies open to the earnest worker. 

AUTUMNAL BEAUTY OF HEDGEROW, WOOD, 

AND GARDEN 

Before leaving this part of our subject we will for a moment direct 

attention to the autumnal beauty of our hedges, woods, and gardens. Few 

dwellers in the country can have failed to notice the infinite variety of 

colour which attaches to the dying foliage, and even those in towns must 

xiv

INTRODUCTION 

be familiar with the exquisite colouration of the Horse-Chestnut leaves in 
the early stages of decay, and the many beautiful gradations through which 
the leaves of the Elms pass in their change from the sombre green of summer 
to the golden yellow at their fall. 

In an Oak wood we may see every variety of green and every variety 
of brown, while among the Beeches we have a long range from modest 
brown to glowing orange. In the Hedge Maple we find every shade of 
green, brown, and orange suffused with gold, and among the Brambles and 
on the Hawthorn we get every possible variation in green, orange, yellow, 
red, and brown. 

Space will not permit of our going through the list of all our common 
trees, but we must pause to mention a few of our cultivated trees and 
shrubs which may be depended on in most years to put on their autumnal 
livery of crimson, scarlet, and gold. The various species of Maple provide 
us with examples of red, orange, yellow, and scarlet, and all the species of 
JEsculus turn yellow. Many of the Thorns (Crataegus) take on brilliant 
shades of red, bronze, orange, and scarlet, and among the many fine examples 
of yellows may be placed the Poplars, Sycamore, Tulip Tree, Honey Locust, 
and Maidenhair Tree. Among shrubs some of the most striking are the 
Sumachs (Rhus), most of which turn red, while the Barberries furnish us 
with red, purple, and scarlet. The exact nature of the subtle chemical 
changes which take place in the cell-contents of the leaf and produce this 
autumn colouration is not clearly understood, nor is the reason clear as to 
why it varies so much in different seasons, but, as a rule, it seems to be 
best when a warm, moist summer is followed by a dry, sunny autumn, and 
many species colour best when growing in a soil which is not over-rich. 

FLORAL STRUCTURE AND POLLINATION 

Let us for a moment turn our attention to the flowers. We are not 

here concerned with their structure, for that is dealt with fully in the detailed 

descriptions, but we should like to direct the student to the many interest- 

xv c 2 



INTRODUCTION 

ing problems connected with the question of their pollination and fertilisa- 
tion. Nearly all the species dealt with in this work belong to one or other 
of two great classes of Flowering Plants, the Dicotyledons and Gymnosperms, 
the Monocotyledons being represented by a very few species. The Gymno- 
sperms, or plants with naked ovules, have flowers which are unisexual and 
destitute of calyx and corolla, and are entirely wind-fertilised. There is a 
general broad resemblance of structure in the various genera and species, 
and the fertilised ovules take from one to three years to become ripe seeds. 
In the Dicotyledons we have a marvellous diversity of floral structure, and 
there is no doubt that each peculiarity has its own significance. 

Generally speaking, self-fertilisation is not advantageous to the plant, and 
the structural differences are usually a means of preventing this, and at the 
same time an aid to cross-pollination. Our catkin-bearing trees are con- 
spicuous examples of this, for their flowers are nearly all anemophilous, the 
females having well-developed and usually projecting stigmas, and the male 
flowers being easily shaken in the wind, while, as an aid to the better dis- 
persal of their pollen by the wind, they almost universally blossom before 
the leaves are fully developed. Irregular and conspicuously coloured flowers 
are nearly always pollinated by insects, and our trees and shrubs provide us 
with many examples, the greater number perhaps belonging to the Order 
LeguminosEe. The latter are for the most part pollinated by bees, but 
among entomophilous flowers we have many which for the perpetuation of 
the species are dependent on the visits of butterflies or moths, wasps, flies, or 
beetles. We cannot stay to discuss the many questions connected with colour, 
perfume, nectaries, &c, but will direct the reader to the very admirable 
chapters on the subject to be found in various well-known botanical works. 

COMMERCIAL PRODUCTS OF FLOWERS OF TREES 

AND SHRUBS 

As commercial products the flowers of trees and shrubs are of not much 

value, but in two instances the unopened flower-buds are used commercially, 

viz., in the case of Capers, which are produced on a small shrub (Cappa?'is

spinosa) grown in South Europe, and with Cloves, which are the product of 
an East Indian tree (Caryophyllus aromaticus) belonging to the Order Myrtaceae, 
which includes other such useful products as Allspice, Pomegranate, and the 
many species of Eucalyptus. Another most interesting example is provided 
in the Fig, popularly regarded as a fruit, and used as such in dessert, but 
which is in reality an inflorescence or collection of flowers. 



FRUIT AND SEED 

In our review of the tree we now come to the most essential point, the 
fulfilment of the Creator's command, " Let the earth bring forth grass, the 
herb yielding seed, and the fruit tree yielding fruit after his kind, whose 
seed is in itself upon the earth." Since the dawn of creation Dame Nature has 
been working out this scheme, and the results of her handiwork are around 
us in the endless variety of shape and form evolved by the fruit and seed, 
and the innumerable mechanical contrivances adopted for their dispersal. 

Time and space will not permit of our entering into details of the Classi- 
fication of Fruits, but we shall find that the majority of those dealt with 
may be placed under the headings of pomes, drupes, berries, capsules, 
samaras or cones. The first three are fleshy fruits containing seeds, and in 
their dissemination birds and other animals take an active part. The 
succulent portion of such fruits is greedily devoured, but the seeds usually 
resist digestion, and are sometimes transported to great distances where, 
under favourable conditions of soil, moisture, and temperature, they may 
continue the race. 

The true capsules liberate their seeds through toothed openings or pores, 

or by forcibly bursting open in well-defined directions. The pod or legume, 

which is often described as a capsule, also bursts to disperse its seeds, and 

sometimes propels them a considerable distance. In the samaras or winged 

fruits, and in the winged seeds of the cones, we have aids for their dispersal 

by the wind, and many other interesting forms of fruit and seeds of less 

frequent occurrence may be met with. 

xvii 



INTRODUCTION 

Among the useful products of trees may be mentioned the orange, lemon, 
citron, lime, banana, and date: nuts include almonds, Brazil nuts, chestnuts, 
and walnuts ; and useful beverages are obtained from cocoa and coffee. 

Many fruits and seeds are subject to attack from insect larva?, especially 
of beetles, many of which are known as weevils. Many trees and shrubs 
lend beauty to the autumn through the charming effects produced by their 
conspicuous and brightly coloured fruits, and to the student of Nature they 
have the additional merit of encouraging bird-life, for the delicacies displayed 
in such profusion are eagerly devoured by our feathered visitors. 



FINE-FRUITING TREES AND SHRUBS FOR 
DECORATIVE EFFECT 

Of all the natural orders into which our plants are grouped none is so 
prolific of fine fruits as the Rosacea?, and many familiar examples are to 
be found among the Roses, Pyruses, Thorns, and Cotoneasters. Many of 
the Rose fruits are extremely beautiful, the most conspicuous being the 
bright red orange-shaped hip of Rosa rugosa, measuring 1 inch or more 
across, and surrounded by leaf-like persistent sepals H inches long. The 
Dog Rose, so familiar in our hedges, is also worthy of note, being deserving 
of a place in the garden, its fruit being, like many others of the genus, a 
beautiful red. 

Varying shades of red, orange, and yellow are provided by the genus 
Pyrus, which includes the Crabs, White Beam, and Mountain Ash. Many 
of the Thorns are very effective, and rarely fail to carry a good crop of 
brightly coloured fruit. Among the best examples we may place the Cock- 
spur, Fiery Evergreen, and Washington Thorns. The Cotoneasters may supply 
us with specimens for the lawn, shrubbery, wall, or rockery, differing so 
widely in habit that one or more can be found for almost any position 
seldom failing to provide an autumn show of handsome berries. 

Of the many other showy species we need only mention the inflated

pods of the Bladder Nuts and Bladder Sennas, the conspicuous white fruits 
of the Snow-berry, those of the Arbutus resembling ripe strawberries, the 
bright orange berries of the Sea Buckthorn, and the Spindle trees with their 
open red fruits revealing the orange-coloured seeds within. The list could 
be extended almost indefinitely, but we have said enough to prove that 
to those who will look for them there are beauties in our trees and shrubs 
at all seasons of the year. 

PENDULOUS TREES AND SHRUBS 

As a last word on the subject of beauty we will call attention to the 
many varieties of pendulous trees and shrubs which we may find in 
cultivation. Very few of these are species coming true from seed, but have 
mostly originated as sports, and are propagated by grafting, cuttings, or 
layers. Some of the best known and most frequently met with are the 
weeping varieties of the Ash, Birch, Elm, Poplar, and Willow. The genus 
Primus gives us several forms of Cherry, and there are pendulous varieties 
of Alder, Hazel, Hornbeam, and Oak. The weeping forms of Holly are 
the best of all evergreen trees with a pendulous habit, and among Conifers 
we have pendulous varieties of Cedar, Cypress, Juniper, Larch, Yew, and 
others to choose from. All such trees and shrubs are seen to the best 
advantage when growing on an open lawn or on the margin of a lake 
or stream. 

THE SCENT OF TREES: THE BEAUTY OF THE LIME 

The scent given off 1 by some kinds of trees and shrubby plants — and the 
latter especially — is one of the many features of the countryside and the 
garden. 

Whilst comparatively few of our commoner British trees are aromatic, 

exception must be made in the case of the Lime. When laden with its light 

yellowish tassels of bloom during the wealth of summer, when the honey 

bees are taking toll from the nectar and so energetically pursuing their 

xix

INTRODUCTION 

sweet pillage amongst the flowers, then it is that few scents in the country- 
are more beautiful or enticing. Perchance the lovely breath from the sweet 
violet wafted on the breeze from some sun-kissed bank, or the delicious 
perfume from the meadow-sweet along some secluded streamside, or the 
fresh, invigorating air after a shower of rain, or the scent from the hayflelds, 
may vie with the Lime in luxury of aroma, but the latter surely eclipses 
all. Of an evening, when the heat and dust of the day have departed, and 
twilight replaces the dawn, when the little pipistrelle bat is commencing 
its nocturnal exploitations, and the bees have gone home to slumber after the 
day's pillaging among the flowers, then it is the Lime is at its best. We 
really do not know of any other British tree which gives to the country 
such a delightful scent, nor — with the exception of the male Sallow blossoms 
in the early spring, the Brambles in the summer, and the Ivy in the autumn 
and winter — one that attracts such an abundance of insect visitors. 

It is astonishing to notice, however, how few people appear to hear 
the pleasing monotone, or stop to inhale the sweet aroma. Yet most of 
us seem to love trees, and nearly every one is passionately fond of flowers. 
Many of our more unfortunate fellows, penned up in town or city, who for 
a few brief hours pass a week end with us in the country, crave for a sight 
of, and a meander through, some tangled and untrammelled piece of wild 
England, some lonely copse, some secluded greenwood where the squirrel 
loves to gambol in the tree tops playing hide-and-seek, and the jay and 
the woodpecker delight in sounding their loud clarion cry. 

COMPANIONSHIP OF TREES 

There is companionship in trees. Shakespeare has written of sermons in 
stones. Verily, if there be sermons in stones, there are sermons and music 
and congregation combined in trees. 

Have you ever wandered alone through some favourite belt of wood- 
land listening to the feathered choir, stooping to caress some vegetable 
treasure at your feet, watching the rabbits scuttle away at your approach, 

or a crafty weasel creeping snake-like through the undergrowth ? You 

xx 



/ 



INTRODUCTION 

inhale the pure air, gain inspiration from Nature's inexhaustible storehouse 

at every step you take into her sacred fastnesses ; the wood is in itself a 

rich museum, a fairy forest, full of wonders untold, secrets as yet unravelled, 

pathways as yet untrod, and the trees seem so very near that you know not 

solitude during your interviews and association with them. 

" At the gates of the forest," says Emerson, " the surprised man of the 

world is forced to leave his city estimates of great and small, wise and foolish. 

The knapsack of custom falls off his back with the first step he makes into 

these precincts. . . . Here is sanctity which shames our religions, and reality 

which discredits our heroes. . . . The tempered light of the woods is like 

a perpetual morning, and is stimulating and heroic. Here no history, or 

church, or state is interpolated on the divine sky and the immortal year ! " 

Yet, while the birds and other animals interest and amuse you with their 

winning ways, and you note the smaller plants, the crafty woodbine and 

the twining bryony, that by force of youthful sap thrust themselves over and 

around their fellows, it is the larger trees which look down upon you and 

seem to preach a living sermon, seem to proclaim a real message. The 

wind gently rustles the leaves so that they shimmer in the sunlight and 

thus produce a kind of woodland lullaby, a whisper of welcome, a message 

of friendliness, a spirit of companionship, a symphony of love. 

Never need one be dull or morose when in the neighbourhood of trees, 

and if people generally realised what we owe to them for the purposes of fuel, 

food, medicine, raiment, and timber, they would undoubtedly be much more 

highly regarded than they are to-day. They are happy sanctuaries for birds, 

squirrels, bats, a vast array of insects, and other animals ; they improve the 

landscape, temper the winds, consolidate the soil, give off an abundance of 

life-giving oxygen and breathe in the bad gases that we breathe out, and 

generally add a complete charm to the town or countryside such as no other 

branch of Dame Nature's fruitful family can ever hope to do. 

Surely our natural love is for trees, for the little copse, the wild woodland, 

or the virgin forest. From the latter we have, as it were, not long since 

emerged ; our woodcraft in some remote districts has lost none of its cunning. 

xxi 



INTRODUCTION 

Far hack in distant ages we learn of tree-worship, of the mysterious in- 
fluence surrounding the grove. "Trees," says Pliny, "were the first temples,'' 
and although we have lost some of the poetic fancy connected with trees 
we have learned much of their life histories. The mystery, however, is still 
there, and to probe into the secrets affords an abundance of wonder and 
delight, 

OUR WOODLANDS OF TO-DAY 

To-day, when the woodman uses his axe so largely and so often, our 
great forests and woods are denuded of the monarchs among which the deer, 
the wild boar, the bear, the wolf, and other animals once roamed, and we 
see in many instances the wood of our youth converted into the homeliness 
of the spinney or the copse. And what a remarkable change takes place in 
the living garment when light and air are let into the woodland. Presto ! 
was ever anything more magical or remarkable ? Have you never witnessed 
such a transformation ? If not, then your experience has been very dissimilar 
to our own. Fresh plants have sprung up with amazing rapidity and car- 
peted the ground with their virgin growth ; a new young wood has been 
silently ushered into the world, and between the few remaining trees of an 
older growth that stood sentinel-like, the earth was literally festooned with 
a profusion of herbage. 

The whole panorama requires to be actually seen to be appreciated, and 
as the various wild tenants inhabit the copse, and plants appear, disappear, 
and re-appear, there is a whole succession of interesting phenomena displayed 
to view which cannot fail to fill one full of gratitude and wonder. 

A GOOD STORY BY DEAN HOLE 

"'Tis a beautiful tree," our neighbours say, and that is mostly the only 

comment they have to make. That is the Alpha and Omega of it all! 

This reminds us of a story told by the late Dean Hole in his charming 

xxii 



/ 



INTRODUCTION 

book, "Our Gardens." It is worth retelling here. The Dean is writing in 
his own inimitable way of the various persons he approached as to their 
opinion of what a garden was for, and he says that "the unkindest cut of 
all, so common that it makes one callous, comes from those visitors who 
' would be so delighted to see our garden ! ' and they come and see, and for- 
get to be delighted. They admire the old city walls that surround it, they 
like to hear the cawing of the rooks, they are pleased with the sun-dial and 
the garden chairs, but as for horticulture they might as well be in Piccadilly ! 
They would be more attracted by the fruit in Solomon's shop than by all 
the flowers in the border. I heard a lady speaking to her companion of ' the 
most perfect gem she had ever seen,' and when, supposing that reference 
was made to some exquisite novelty in plants, I inquired the name and 
habitation, I was informed that the subject under discussion was ' Isabel's 
new baby.' ' Ladies,' I remarked, with a courteous but scathing satire, ' I 
have been a baby myself, and am now a proprietor, but I am constrained to 
inform you that this is a private, and not a nursery, garden.' ' 



THE MISSION OF THE TREES 

It is an undisputed fact that few people stop to admire a tree's 
symmetry, its bark, its chaste and delicate filigree and lacework during 
winter, or to study the functions of the leaves, the flowers, the roots, the 
branches, the fruit, its uses ; just its beauty, that is all. 

Why do trees unfold themselves with such lavish and remarkable 
splendour I Why are so many so comely, so attractive, so inspiring, so 
friendly, so companionable, so neighbourly (often more so than their human 
prototypes) ? No flower " is born to blush unseen, and waste its sweetness 
on the desert air," for, although many please and satisfy us, it is not for us 
alone that they have, through the countless ages, evolved into the wonder- 
ful floral treasures we see before us to-day. 

No tree or shrub, nor herbaceous plant, wastes its sweetness on the desert 

xxiii 



INTRODUCTION 

air. Each in its way has a mission to fulfil, business to carry out, a 
message to deliver, a duty to perform. 

Their beauty is not meant for sentiment nor display, but, as the late 
Hugh Macmillan has so truly said, "for use in the economy of the plants 
that produce it, so that they could not be spread over the earth, over those 
desert places themselves, without that beauty." 



AN ENGLISH WOOD IN SPRINGTIME 

To be in an English wood in the early springtime, to observe the Hazel 
catkins swinging like so many fairy bells on the leafless branches, is one of 
the greatest delights which could come to any one interested in outdoor life. 
The noting down systematically, season after season, of the first leafing of the 
green canopy above, and the date of flowering, fruiting, and fall ; the arrival of 
some favourite bird among the pliant branches ; the appearance of the first 
brimstone or tortoiseshell butterfly ; the songs of newly awakened birds ; 
the peeping from its woodland and leaf-strewn bed of the pale primrose ; 
the hum of insects ; the frolics of wild folks, and generally the resurrection 
of everything that lives out of doors and likes the sun, — all these tend to 
make an April morning in the wild greenwood the very essence of quiet 
and unobtrusive enjoyment, and result in a rich harvest to those possessing 
the seeing eye. 

Here one may note and appreciate to the full the music of the feathered 
choir, the murmur of the wind, the ripple of the leaves, the distant lullaby 
of the sheep-bell, and receive with reverence the message of the trees. 

There is no doubt, as Richard Jefferies has said, that " if you wish your 

children to think deep things, to know the holiest emotions, take them to 

wood and hills, and give them the freedom of the meadows. Under the 

green spray, among the Hazel boughs, where the nightingale sings, they 

shall find a secret, a feeling, a sense that fills the heart with an emotion 

never to be forgotten."

INTRODUCTION 



MORE WOODLAND PICTURES 

There is a peculiar fascination in being in a wood at any time, but 
especially so in the early morning when the sun is just flashing its rays 
across the dew-spattered meadows and through the fast-leafing woodland of 
the first days of spring. 

Towards the gloaming hour, too, when the chorus of thrushes and 
blackbirds is such a feature of our English springtime, there is some in- 
describable charm in wandering silently through a wood, and again, in the 
very heart of summer, it is cool and refreshing to dive into the greenwood's 
welcome shade. The birds have by then mostly ceased their minstrelsy ; 
perchance a startled rabbit skips away as you tread on a piece of dead 
wood which goes off with a loud report ; an inquiring robin and a few 
tits are busy on the moss-strewn tree trunk yonder, but even the indus- 
trious insects seem to be taking life very quietly and soberly. 

How still everything is ! Not a leaf stirs. The trees bear the full com- 
plement of their summer dresses ; they are simply wreathed in foliage, and 
many are already in fruit. You rest awhile near the old spot you know 
and love so well. A turtle-dove slips silently off her nest, and you would 
not have noticed her at all only your eye chanced to wander towards the 
spot from whence she rose. 

What pictures come to mind as you sit there soliloquising. You think first 
of those cheerless winter days when it was cold and blustering in the open, 
but mild and inviting among the trees. Then later comes the remembrance 
of the first little tuft of red upon the Hazel, the bursting of the Sallow into 
a blaze of splendour, the feathery tufts upon the Larch, the green carpet 
afforded by the Dog's Mercury, the gradual robing of the woodland, the 
mating of birds, the hum of insects, and finally the full glow of spring. 

These thoughts have often occurred to us as we have sought refuge in the 

wood from the rush and bustle of everyday life. We have tested it at all 

times and at all seasons, and it has never disappointed us. When within 

xxv d 



INTRODUCTION 

it we are happy ; we are on familiar terms with every tree almost ; we 
feel somehow that we are part and parcel of the green canopy above and 
the soft verdure beneath, but when we leave it behind and step out into 
the wide and often unthinking world, we feel we have lost a friend. Yet 
we are contented to know that we may, and shall, return to seek com- 
panionship and fellowship with the trees and flowers again, and thank 
Heaven that we have imbued within us a sense of the beautiful in Nature's 
wonders. 

The quietude of summer in the woodland is so entirely different from the 
full gush of spring, when the re-leafing of the trees, the thrusting above 
earth's surface of the first flowers, and the fussy courtships of birds engage 
and occupy one's attention. 

To our mind one of the greatest experiences is to commune with 
Nature in solitude during the full glow of summer in some sylvan retreat, 
some lonely copse, some secluded woodland glen. 



HOW TO READ THE STORY OF THE YEAR 

To know and appreciate a wood properly, and to be on intimate terms 
of acquaintance with trees, birds, and flowers, it is essential to walk 
lovingly and trustfully with them at all seasons of the year. 

It has been our pleasant and profitable enjoyment to ramble through 
woodlands far from the madding crowd for many years past, and through- 
out the whole year. It is only by this means that one can appreciate the 
rich charm of Nature, and be able to piece together in a humble way the 
great story of the year. 

As a result one indelibly associates the environment of a bird, an insect, 

a flower, or other inhabitant of the fairyland of living things, with the 

particular object one has in mind. When we think of the wood wren we 

at once associate it with a Beechwood, among the stately temples and 

avenues of which this bird delights to pass the summer hours. 

When we think of squirrels and jays, of golden-crested wrens and 

xxvi 



/ 



INTRODUCTION 

doves, the groves of sombre, thickly-matted Firs and Pines at once come 
into view. The Oakwood reminds us of the nuthatch, the woodpecker, the 
wryneck, the tree creeper, and insects far too numerous to mention. 

The tall Elms are indivisibly connected with the sable rooks ; the ivy- 
clad ruins and the hollow trees with their near relative the starling. The 
mossy nest of the chaffinch is inseparably associated with the milk-white 
bloom of a hedgerow, the nightingale brings to mind the thick retreat of a 
blossoming thorn. 

It is a good thing to be cognisant of the environment of an animal or 
plant, for it is only by this means that a full measure of enjoyment can be 
obtained. Without a knowledge of the habitat of any of Nature's children 
one half the interest and the beauty vanishes, and whilst we are the first to 
recognise the educational advantages of Museums and Gardens, Pestalozzi 
was right when he said : " Lead your child out into Nature ; teach him on 
the hill-top and in the valleys. There he will listen better and the sense of 
freedom will give him more strength to overcome difficulties. But in these 
hours of freedom let him be taught by Nature rather than by you. Should 
a bird sing or an insect hum on a leaf, at once stop your talking ; bird and 
insect are teaching him ; you may be silent." 

If in any measure this work helps to create an interest in, and a love 
for, trees and shrubs, we shall feel amply repaid for the great amount of 
labour expended in its compilation, and it is our earnest hope that not only 
will these trees and shrubs be regarded from the standpoint of beauty, 
form, colour, design, usefulness, ornament, or service, but that those who 
honour us by a perusal of these pages will be able to enter fully into the 
spirit of the lines : — 

" Ye bright mosaics that with storied beauty 
The floor of Nature's temple tessellate, 
What numerous emblems of instructive duty 
Your forms create ! "

CHAPTER I 
INJURIOUS INSECTS 

The number of insects injurious to plants is very large, and their rapid 
increase is often alarming, as in only comparatively few cases are effectual 
remedies available. It is our intention to take a hasty glance at the more 
important of those insects which cause material injury to Trees and Shrubs. 
With the space at our disposal the descriptions must necessarily be brief. 

Among the Coleoptera or Beetles there are many which may be classed 
as Pests. 

The Cockchafer or "May-bug" (Mclolantlia vulgaris) is a large heavy- 
looking reddish-brown insect about 1 in. long. The head and thorax are 
black, the abdomen being of the same colour, with stripes of white hairs 
on the underside. The pointed tip of the abdomen projects beyond the 
elytra. The larvae or " White-grubs " devour the roots of Roses and seedling 
trees, young Oaks and Fir-trees often suffering severely. The adult insects 
live on the foliage of fruit-trees, Roses, and such forest-trees as the Oak, 
Chestnut, and Beech, the needles of Larch and Spruce, and the male cones 
of Scots Pine. The beetles fly in the evening, so must be collected and 
killed during the day. The larva?, which live in the ground for three years, 
may be trapped in pieces of turf laid with the grass downwards. 

The Summer Chafer (Rhizotrogus solstitialis) appears in June and July. 
It somewhat resembles the larger Cockchafer, but is only about jj in. long. 
The larva? live about two years in the ground, and the adult beetles live 
partly on the foliage of Rose-trees. They must be collected in the daytime. 

The Garden Chafer or Bracken-clock {Phijllopertha horticola) is known 

in Wales as the Coch-y-bonddu, and appears in May and June. It is 

about h in. long, the front part of the body being of a metallic greenish 

colour, and the elytra or wing cases of a reddish-brown hue, the male being

very hairy. The larva lives about a year, and the beetle feeds largely on 
the foliage of fruit-trees and Hoses. Being a day-flier, and very active in 
the sunshine, it must be attacked late in the day or when the weather is 
dull. 

The Hose Chafer (Cetonia aurata) is a handsome beetle about '-\ in. long, 
with golden green wing-cases marked with transverse creamy spots, and 
the body coppery beneath. The larvae live underground for two or three 
years, eating the rootlets of Rose-trees, and gnawing off the skin of the 
larger roots. The adult beetles feed largely on the anthers and petals of 
Roses. They are most easily collected on dewy mornings, when they are 
sluggish, or at night. 

The Pine Beetle (Hylesinus (Hylurgus) piniperda) is one of the most 
destructive of forest insects. The mature beetle is about 1 in. long, of 
a dark brown to glossy black colour, thinly covered with brown hairs 
springing from little tubercles, which, on the elytra, are disposed in rows 
between lines of punctures. Eggs are laid in March and April in the thick 
rough bark of recently felled trees, especially Scots Pine and Black Austrian 
Pine. The female lays about 100 eggs, which produce larva? in about a 
fortnight. The larva? feed on the bast or inner bark. The young beetles 
appear in June and July, and then usually bore into the young shoots 
of Pines about 2 ins. beneath the terminal bud, and, tunnelling upwards, 
cause the death of the shoots. The best method of prevention consists of 
leaving autumn or winter felled trees in or near the wood, in order to 
attract the beetles in the breeding season, and then removing the bark 
during May, when the larva? may be destroyed by exposure. 

The Spruce-bark Beetle (Bostrichus {Tomims) typographies) and others 
of the genus destroy Fir-trees by tunnelling just below the bark. As a rule 
they attack sickly trees, but may extend their depredations to healthy 
specimens also. Prevention consists of the timely removal of sickly or 
uprooted trees, and in stripping the bark from logs left lying in the woods 
over summer.

than i in. long, makes up in numbers what it lacks in size, for it is stated 
that as many as 80,000 have been found in one tree. The female beetle 
excavates the bark, making a tunnel about 2 ins. in length, and laying 20-50 
eggs as she advances. These are hatched in about two months, and the 
larva? eat out galleries on either side of the main tunnel. They pupate 
and emerge as perfect insects at the end of May in the second year. 
Brushing the tree with coal-tar is said to have the effect of driving away 
the perfect insects, but if the larvae are allowed to commence their ravages 
there is but little hope of saving the tree. Other members of the genus 
attack the Oak. 

The Fruit-tree Beetle {Scolytus rcgulowts) is a species which frequently 
attacks Apple-trees, and in a less degree the Pear, Plum, Cherry, and Peach. 
The insect seems to have a decided preference for sickly trees and parts of 
branches where there is the least flow of sap. It is barely T \, in. long, and 
black in colour, except the ends of the wing-cases, legs, and antenna?, which 
are of a russet tinge. The eggs are laid in April in a gallery about }, in. 
long, and hatch in a few days. There are at least two generations during 
the year, and the winter is passed in the larval state. Not much can be 
done in the way of prevention except to cut out and burn all infested 
branches during June and remove all sickly trees. 

The Pine Weevil (Hylobius abictis) is a beetle very harmful to the Scots 
Pine, Norway Spruce Fir, and other Conifers, as it feeds in the perfect state 
on the bark of the young shoots. It is dull black in colour, with scattered 
tufts of yellow hairs, and appears in the summer months (May to July). 
It gnaws the buds and bark of the twigs, thus interfering with the develop- 
ment of the tree. The evil is difficult to deal with, but the weevils are 
sometimes trapped in small pieces of bark laid at regular intervals, and kept 
in place by a stone being put over each. In sandy soils trenches are some- 
times dug surrounding new plantations, and into these the weevils fall, and 
may be gathered and killed. 

Other Pine- weevils are Pissodes notatus and P. Pi/ii, both of which destroy 
the branches of Conifers by boring small holes in them and sucking the sap.

TREES AND SHRUBS 

The Apple Blossom Weevil {Anthonomus pomorinn) is a small brown 
beetle, about \ in. long. At the beginning of spring, the female lays 15-20 
eggs, placing one in each flower bud. The larva hatches in 5-9 days, and 
proceeds to feed on the essential parts of the blossom. In about 8 10 days 
the larva changes to pupa, and at the end of another 10 days the perfect 
weevil appears and escapes by boring a hole through the petals. Through 
the summer it lives among the leaves of fruit-trees and hibernates under 
moss or bark, or beneath stones and rubbish around the trees. The best 
preventative is clean culture, all lichens, moss and rough bark being removed 
from trees. On dull days the beetles may be shaken from the branches 
into cloths, and as many as 1000 weevils have been shaken from a tree 
at one time. 

The C lay-coloured or Raspberry Weevil (Otiorrhynchus picipes) is about 
J in. in length, and has the somewhat brown elytra thickly covered with 
light-coloured scales, giving it the colour of clay. Eggs are laid in the 
summer in the ground, and the larva? feed on roots of raspberries, straw- 
berries, and other plants throughout the autumn until the spring. The pupal 
stage lasts about a fortnight, and the perfect weevils then appear, starting 
on a life of depredation, feeding on the leaves and young shoots of rasp- 
berries and fruit-trees. The weevils may be caught by holding tarred boards 
near the ground at night, and tapping the stakes so that the insects fall 
into the tar. 

The Red-legged, or Plum Weevil (Otiorrhynchies tencbricosus) is J jj in. 
long, black and shiny, with dull red legs. The eggs, laid underground, hatch 
in August and September, and the larvae feed upon strawberry and other 
roots till the following March or April. The perfect beetle is particularly 
partial to the foliage of Plum-trees, but is also destructive to the Raspberry, 
Cherry, Peach, Apricot, and Nectarine. Being nocturnal in its habits, it is best 
caught at night. 

The Nut-Weevil (Balaninus micurn) is \ in. long, dark brown or black, 

with a long, reddish-brown beak supporting elbowed antenna? at about the 

middle of its length. In June one egg is laid in each nut. The larva feeds 

xxxii 






INJURIOUS INSECTS 

upon the seed, or kernel, and when full grown emerges from the shell, 
leaving behind a mass of dark, powdery excrement. The pupa lives in the 
ground till the following May, when the beetle comes forth and feeds on 
the young buds of the Hazel. The wild plant should not be allowed to 
grow near cultivated Hazels or Filberts. All fallen nuts should be collected 
and burned. The weevils may be shaken from the trees into cloths or on 
to tarred boards. 

The Order Hymenoptera includes the Bees, Wasps, Ants, Gall-flies, 
Saw-flies, and Ichneumons. Many of these may be considered as injurious 
insects, some in relation to our present subject. 

The Rose Leaf-cutting Bee {Megachile centuncularis) causes much annoyance 
to Rose growers by cutting out semicircular pieces from the foliage. The 
pieces are used for lining a circular tube formed either in decaying wood 
or in brick walls, or sometimes in the ground. At the bottom of the tube, 
which is often some inches in length, the female bee lays an egg, and, having 
provided a store of food consisting of pollen and honey, closes up the cell 
with more circular leaf-sections, and continues the process until six or more 
cells have been formed. Complete metamorphosis takes place in the cell, 
and the leaf-cutting bee emerges in the next season. 

The Common Wasp (Vespa vulgaris) does great injury to ripe fruits. 
The nest is commenced by a single female, which has survived the winter, and 
is afterwards enlarged by the exertions of her progeny, the work continuing 
till the cells may number many thousands. Prevention is best secured by 
encouraging the capture of the females or Queens in the spring. Nests in 
holes and trees may be destroyed in various ways, and the insects may be 
caught in simple traps made of bell-glasses inverted one over another, or 
even a bottle containing a sweet fluid. 

The so-called Wood- wasps include two well-known injurious insects, the larva.' 
of which feed in the wood of Conifers, boring tunnels about ■?. inch in 
diameter. 

The Giant Sirex {Sirex gigas) is the first of these. The female is yellow, 
with two black bands, and a stout ovipositor, the body measuring from 



xxxm 



TREES AND SHRUBS 

lj in. to 1.1 in., and the ovipositor being about half as long as the 
body. By means of the "saw" contained in the ovipositor the insect bores 
into the bark of Spruce and Silver Firs, and occasionally Larch, depositing 
1 egg in each hole made. The length of the larval stage is not easily 
ascertainable, but the perfect insects emerge from July to September. 

The Steel-blue Sirex (Sirecc juvencus) is slightly smaller than the first 
species, and is usually of a dark steel-blue colour, with red-brown feet ; in 
the males several segments of the abdomen are rusty-red. The wings in 
both sexes are yellowish. This species prefers the Scots Pine. 

It is impossible to destroy the larvae in infested trees. All that can 
be done is to cut down such trees, and remove all sickly trees and fallen 
brandies and trunks. The timber is of little value, save as firewood. 

The next section of the Hymenoptera contains a large number of boring 
insects known as Saw-flies, the boring instrument being modified into a 
pair of toothed saws, which are used for cutting incisions in leaves, or in 
the tender bark of twigs, in which to deposit the eggs. The larva? much 
resemble caterpillars in appearance and habits, and the pupa? are enclosed 
in cocoons. 

The Pine Saw-fly {Lophyrus pini) bores into the needles of Scots Pine, 
and deposits a large number of eggs. The female is pale yellowish-white, 
with black head and breast, the wings expanding £ in. The male is 
black, and the wings measure h in. across. The light greenish-yellow larvae 
are gregarious, and do much damage by gnawing and totally destroying the 
needles. There may be two generations in the year. In gardens and young 
plantations hand-picking may be found an effectual remedy, but in older 
woods it is impossible to cope with the pest. 

There are several species of Lophyrus which attack Conifers, and also 
some species of Lyda. The latter are semi-social, spinning a common web, 
but each also spinning an inner tube for itself. Various species attack fruit- 
trees, Alders, Birches, and Willows. 

The Gooseberry and Currant Saw-fly (Nematus ribesii) is very trouble- 
some in plantations and gardens in some seasons, and is probably the most 



xxxiv 






INJURIOUS INSECTS 

familiar. When once established it is most difficult to eradicate, and the 
larvae will often completely strip the bushes of their leaves, together with 
the young fruit. The fly appears in April, the female being about ?. in. 
long, with a wing expanse of over \ in. Eggs are laid on the underside 
of the leaves, and hatch in about eight days. After the first change of skin 
the larvae are green, with numerous black spots. Having fed for about twenty 
days, they spin cocoons upon, or just beneath, the surface of the earth, and 
may produce a summer brood after another twenty days. They may, how- 
ever, burrow more deeply in the ground, and remain there till the next spring. 
Hand-picking and spraying may be resorted to in the earliest stages, or lime 
may be dusted over the bushes when wet. The ground under infested bushes 
should be dressed with quick-lime in the autumn, being dug deeply to destroy 
the cocoons, and the ground is sometimes beaten down in spring to prevent 
the flies coming up from the cocoons. 

The Pear and Cherry Saw-fly {Eriocampa limacina) and others of its genus 
are known in the larval stage as Slugworms, a name made very appropriate 
by reason of the dark, green, slimy exudation which covers the body in the 
early period of its growth. At this time the larva resembles a malformed 
slug or tadpole, and it spends the time in eating away all the soft tissues 
from the upper surface of the leaf. It attains a length of nearly h in. at 
the end of a month, and after losing its slug-like character, pupates in the 
ground in a cocoon of silk and earth. The pupal stage lasts two weeks in 
the summer, and there may be two or more broods. The late brood pass 
the winter in the larval stage beneath the earth, and pupate in the spring. 
The larva? infest fruit-trees, especially Pear and Cherry, and are occasionally 
seen on some species of Thorns, as well as Oak, Birch, and other forest-trees. 
Paris Green, Hellebore wash, or arsenate of lead are sometimes used before 
the fruit is ripe. The ground round infested trees should be well dug and 
prong-hoed in early spring, and quick-lime hoed in, after which the earth 
may be beaten down to prevent the flies coming up. 

The Rose Slugworm {Eriocampa rosw) works in much the same way as 
the previous species. The larva is pale yellowish-green, with a darker line 



xxxv 



TREES AND SHRUBS 

down the back. Eggs arc laid in May in the midribs of the leaves, and the 
lame are busily feeding in June. After two or three weeks they pupate in 
the ground, emerging soon afterwards to give rise to a second brood of larvae 
in August or September. The larva- may be killed by spraying the Hose 
bushes with Hellebore wash or Paris Green. The surface soil may be 
removed in winter, and either deeply buried or burnt, fresh mould being 
put over the roots. 

The Leaf-rolling Saw-fly (JBlennocampa pusiHa) attacks both wild and 
cultivated Roses. The short, stumpy, green larva? fold down the sides of 
the leaflets and live in the retreats. This folding over prevents the leaf 
performing its proper functions, and causes it to shrivel and die, after which 
the larva removes to another leaf. The larvae enter the soil in August, 
pupate in the early spring, and the flies emerge in May and June. The best 
treatment is to pick off the folded leaves when first seen, and destroy them 

The Rose Emphytus (Emphytus cinctus) is another common and hurtful 
species. The larvae are green, and covered with small white spots. They 
eat the leaves entirely away, holding on by their front feet to the edge, and 
curling the rest of the body in all manner of shapes. When at rest they 
lie curled up in a ball on the underside of the leaves. The full-fed larvas 
bore into the branches and pupate in the following spring. 

Many other Saw-flies belonging to the Genera Emphytus, Cladius, Hylo- 
toma, Poecilosoma, and Lyda are injurious to Roses. The chief remedies 
are (1) hand-picking, (2) spraying with Hellebore wash or arsenate of lead, 
(3) removal of surface soil to a depth of a few inches in autumn, and (4) the 
burning of all dead wood and loose dead leaves, &c. 

The Order Lepidoptera — Butterflies and Moths — includes a very large 
number of injurious insects. We can call attention to only a few. 

The Goat Moth (Cossus Ugniperda or Trypanus cossus) is one of the largest 
and most destructive of British Moths. The perfect insect measures 3 ins. 
across the fore-wings, which are ashy brown clouded with grey, the hind- 
wings being brownish-grey. The larva is smooth, with short scattered hairs ; 
the sides and under surface are a dirty yellowish or flesh-colour ; the back is dark 



XXXVI 






INJURIOUS INSECTS 



red, and the head black. When fully grown the caterpillar measures 4 ins. 
in length, and is as thick as a man's finger. It lives in the wood of Willows, 
Poplars, Ash, Oaks, Birch, and fruit-trees. After two or three years it 
makes a cocoon of chips of wood in which to pass the pupal stage, and 
emerges as a perfect insect in June or July. Infested trees are of little 
use but for firewood. 

The Wood Leopard Moth (Zeuzera cesculi or Zeuzera pyrind) is white, 
with numerous blue-black spots on the wings and thorax. The female mea- 
sures 2|-2f ins. across the wings, and the male about half the size. The 
larva is nearly 2 ins. long, yellow, with black spots. It lives in the wood 
of various trees, principally Pear, Apple, Elm, Willow, and Plum. The 
moth is seen from June to August. Flying somewhat heavily in the even- 
ing, and resting in the daytime on the trunks of trees, it becomes an easy 
prey to many birds. Titmice and other small birds eat the eggs, and the 
green woodpecker is serviceable in taking the caterpillars from infested trees. 
Little can be done to prevent the attack or to check its progress. 

The Pine-shoot Tortrix (Retinia buoliana) is a small moth with reddish- 
orange fore-wings measuring nearly 1 in. across. In July the eggs are 
laid singly on the terminal buds of young trees of Scots Pine. The small 
dirty brown larva spends the winter in the bud, and in the spring hollows 
out the leading shoot and most of the lateral buds, causing the stem to take 
an objectionable twist. 

The Pine Looper or Bordered White Moth (Bupahts piniarius or Fidonia 
piniaria) abounds in Fir-woods in May and June. The male is whitish or 
yellowish-white and the female yellowish-brown. The green larva feeds on 
the needles of Scots Pine from August to October. The humus matter 
should be searched for pupae in autumn, and if many are present the leaf 
litter should be burned. 

The Pine Beauty (Panolis (Trachea) piniperda) is found in Fir-woods in 
March and April. The patches of pale orange on the reddish-brown fore- 
wings make it impossible to mistake this moth, which is often seen on Sallows. 

The larva is green, with five white longitudinal stripes, and feeds on the 

xxxvii e 



TREES AND SHRUBS 

needles of Scots Tine in July and August, and may completely defoliate 
the tins. The pupal stage is passed in the leaf litter on the surface of 
the soil. 

The Tale Tussock Moth (DasycMra pudihiinda) has pale-grey wings measuring 
14 2\ ins. across in the female, and somewhat smaller in the male. It is found 
in May and June. The beautiful larva is known as the Hop-dog from being 
found in hop-gardens. It is greenish-yellow, with velvety black incisions 
and four yellow tufts of hair on the back, and a single dull-red tuft on 
the last segment. It feeds from August to October on the foliage of Lime, 
Oak, Beech, Birch, Hazel, Willows, Poplars, Walnut, Fruit-trees, and Roses. 
Infested trees may be banded with tar at about 9 ft. from the ground, before 
the eggs are hatched. Rose-bushes may be sprayed with arsenate of lead. 

The Black Arches or Nun Moth {Psilura (Lymantria) monacha) is somewhat 
local in England, but on the Continent it is one of the worst of forest pests. 
The wings are 1-2| ins. across, white, with numerous irregular, transverse 
black markings, and the terminal half of the body is pinkish. The female 
is provided with a long ovipositor, used for laying the eggs in deep crevices 
of the bark. The moth appears in July and August. The larva is brownish- 
green, grey or black, with tubercles bearing blue and red hairs. It feeds 
from May to July on the needles of Spruce and Scots Fir, and on the leaves 
of Oak, Beech, Birch, and Apple. In the pine forests the caterpillars waste 
as much as they devour, biting the pine-needles through at the middle, and 
eating only the short stump. Rings of tar will prevent the larva? from 
reaching the tree-tops, both when newly hatched, and after letting themselves 
down by long silken threads. The sticky band intercepts their progress up 
the trunk, and they die in thousands for want of food. It is said that on the 
Continent this treatment has saved many forests. 

The Oak-leaf Roller or Green Oak Moth (Tortrix viridana) abounds at 
the end of June and in July. The fore-wings are bright light green with 
sulphur-coloured fringes, and expand f in. The hind-wings and abdomen 
are grey. The larva is light green, ornamented with small black dots, and 
feeds on Oak, Hornbeam, and Sallow, living in such quantities on the first-

named as to become a pest. The leaves are at first slightly bitten, then 
rolled into a tube and more thoroughly devoured. This continues through 
May and June, and about midsummer a cocoon is formed on the bark or 
amongst the twigs and remnants of leaves, the winged insect appearing in 
about three weeks. 

The Larch Mining Motli (Coleophora laricella) is a small narrow-winged 
moth measuring about \ in. across the fore-wings, which are greyish fuscous. 
The eggs are laid in the needles in May and June. The small larva lives 
in a case formed from a hollowed-out Larch needle. In this it hibernates 
through the winter, and on again becoming active, it doubles its accommodation 
by attaching a second empty needle to the side of the first, and then passes 
through the pupal stage, the moth appearing at the end of June or in July. 
The workings of this pest are said to be a predisposing influence to the 
attack of Larch Canker. Prevention seems to consist in planting Larch 
upon suitable situations where the soil is good and naturally well-drained, 
with free circulation of air about the crowns. 

The Lackey Moth or Tree Lackey (Clisioeampa (Malacosoma) neustria) and 
the next species to be described are often called " Tent Caterpillars " on account 
of the larva? forming tent-like nets of silk on the trees, in which to live 
during their early existence. The Lackey is very variable in size and 
colouring, measuring in in. across the wings, which are rusty reddish- 
brown, yellowish-brown, ochreous, or brick-dust red, the hind-wings being 
often paler. It is common in the south, west, and middle of England, not 
occurring beyond York, and is on the wing in July and August. The eggs 
are deposited in a kind of bracelet around the smaller shoots of several trees, 
and hatch in the following April or May, the larva? living till June under 
a common web. Almost black at first, they afterwards become brilliantly 
coloured, being bluish-grey with orange-red stripes and a white dorsal line ; 
the head also is bluish-grey, with two black dots. Having reached H in. 
in length, the larva spins a cocoon of silk, colouring it with yellow crystals of 
oxalate of lime, and attaching it to leaves or bark, or on wall, fences, &c, 

indeed almost anywhere above ground. The pupal stage lasts 2-3 weeks.

TREES AND SHRUBS 

The larvae do considerable damage to Apple, Pear, and Plum, and are also 

frequently found on Hawthorn and Blackthorn, and less often on Oak, Elm, 

and Hazel. As preventatives, all egg-bands should be collected and burnt 

in winter: tents should be collected and burnt in summer on a dull day 

or in the evening, boards or a cloth being held underneath to catch the 

larva? which fall. Spraying with arsenate of lead has the advantage of killing 

the larva 1 without damaging the foliage ; Paris Green or London Purple 

may also be used for spraying. 

The Brown-tail Moth (Porthesia (Euproctis) chrysorrhcea) has white wings 

and body, and a tuft of brown hairs at the end of the abdomen. The 

moth appears towards the end of July and in August, and the female lays 

a patch of golden-coloured eggs on the under surface of the leaves, covering 

over the batch with hairs from her tail. The eggs hatch in August, and 

the larva. 1 live at first in a common web. They are afterwards greyish-black, 

with reddish hairs ; two reddish-brown lines run down the back, beneath 

which is a row of whitish streaks ; a tuft of hair proceeds from a fleshy 

protuberance on each side of the head. The larva? feed on the same trees 

as the Lackey, and the preventive treatment is the same. 

The Small Ermine Moth (Hyponomeuta padella) is a tiny moth with a 

wing stretch of about f in. The fore-wings are white with a greyish tinge, 

traversed longitudinally by three rows of black dots, about thirty in 

number; the hind-wings are brownish-grey, with light fringes. The moth 

appears in July and August. The larvae are grey, with black spots. They 

appear in May, and live gregariously in a veil-like web on Apple, Plum, 

Hawthorn, Sloe, Mountain Ash, and other trees, often doing considerable 

damage. Other species feed on Spindle. The webs should be destroyed 

in the early stages, being pulled down and burned. The trees may be 

syringed with various solutions, one of the best being made with paraffin 

and soft soap. 

The Winter Moth (Chrimatobia brumata) is abundant in October and 

November, and later in mild seasons. The male measures slightly over 1 in. 

in expanse, the fore-wings being greyish-brown, with several indistinct wavy 

xl 






INJURIOUS INSECTS 

lines. The female has only rudimentary wings, and crawls up the stems 
of fruit-trees and others to lay groups of eggs in the chinks of the bark, 
as many as 200 eggs being laid by one moth. Roses growing in kitchen 
gardens or near orchards are sometimes badly damaged. The pale green 
or yellowish " looper " caterpillars are busy in May, and few larvae do greater 
damage. " Grease-banding " is the most effective method of preventing the 
passage of the wingless females up the trees in autumn and winter. Spray- 
ing with quassia chips or paraffin solution will make the foliage unpleasant 
and distasteful to the caterpillars, so that they die of starvation or fall 
from the trees. 

The Mottled Umber or Great Winter Moth {Hybernia defoliaria) is well 
deserving of its specific name, for sometimes the trees which it attacks are 
left as bare as in winter. The fore-wings of the male are dull yellow, sprinkled 
with rusty brown, expanding about If in. ; the hind- wings are yellowish- 
white, with a small central dot. The apterous female has a stout ochre-yellow 
body, with two longitudinal rows of black spots. As many as 400 eggs 
may be laid by one female. The larva is reddish-brown, with a broad 
sulphur-yellow stripe on the sides. It feeds on fruit-trees, as well as Lime, 
Oak, Beech, Birch, Elm, Blackthorn, Whitethorn, Hazel, and Hornbeam. 
It is prevalent in May and June, and the moth is seen in October and 
November. The treatment is the same as for the Winter Moth. 

The March Moth {Amsopteryx aesmlaria) resembles the previous two 
species in the apterous condition of the female, and the eggs are laid round 
twigs, somewhat similarly to those of the Lackey. The male moth is found 
in March and April, being often seen on gas lamps. The fore-wings are 
of a grey-brown tint, with a darker central transverse band, edged on either 
side with a pale wavy line. The green larva is abundant everywhere in 
May, feeding on Hawthorn, Blackthorn, Oak, Elm, and Lime. 

The Vapourer (Orgyia antiqua) is common not only in the country, but 

may be seen flying about the crowded thoroughfares of large cities. The 

male varies from f in. to 11 in. across the fore- wings, which are of various 

shades of rich chestnut brown, with a white spot near the hinder angle ; 

xli 



TREES AND SHRUBS 

the hind-wings are rust coloured. It Hies from .July to October. The 
female is wingless, and merely crawls from the inside of the cocoon to the 
outside, there depositing the eggs, often completely covering the silken 
case. The larvae appear at intervals lasting over several weeks or even 
months. They range from 1 \ in. to 2 ins. in length, being dark grey, spotted 
with small red tubercles; there are four tufts of ochreous hairs standing 
up from the back of the 5th to 8th segments, two long blackish tufts on 
the 2nd segment pointing forwards, a slender lateral tuft on each side of the 
5th and 6th segments, and one long one on the 12th segment pointing 
backwards. When mature the caterpillar spins a cocoon amongst the 
leaves and shoots, or on the trunk of a tree, or often on a fence. It feeds 
on most trees and shrubs, even including the Cherry Laurel : it is specially 
fond of fruit-trees, Oaks and Roses. All cocoons seen in winter should be 
burned ; spraying with arsenate of lead is useful ; caterpillars may be picked 
by hand, or swept into a cloth and destroyed. 

The Codlin Moth (Carpocapsa pomonclla) is a small species, but its larva? 
are exceedingly destructive to the apple crop. The moth appears in June 
and July. The fore-wings are grey, with wavy lines of a brown hue, and at 
the extremities there are oval patches of a golden colour ; the hind-wings 
have a coppery lustre. The female lays from 50 to 100 eggs, putting one 
on each apple or pear. The pinkish larva bores into the fruit, usually enter- 
ing at the " eye " or calyx, and following the core down to the pips, upon 
which it feeds for some three or four weeks. When full grown, it bores a 
hole to the outside, and, seeking a place of shelter in the cracks and crevices 
of the bark, or other suitable spots, it rests during the winter and pupates 
in the spring. All " windfalls " should be cleared away as soon as possible, 
and if not fit for sale should be given to pigs; strips of cloth or sacking 
should be tied round the trees near the base, and will serve as traps for 
the larva?; spraying with London Purple or Paris Green will kill the larvae 
before they bore into the fruit. 

The Magpie Moth {Abraxas grossulariata) appears in July and August, 

and is common everywhere in gardens. It varies in colouring, but the 

xlii 






INJURIOUS INSECTS 

fore-wings are white, with generally several rows of black spots ; there is 
a yellow blotch at the base, and an orange band beyond the middle ; the 
hind-wings are white, with black spots. The larva resembles the parent 
in being white, with black spots. Emerging from the egg in September, it 
feeds for a short time, then hibernates amongst the leaves and rubbish, 
and reappears in the spring. During May and early June it feeds princi- 
pally on Currant and Gooseberry foliage, but also on Raspberry and Black- 
thorn. The pupa is black, ornamented with three orange rings, and is often 
suspended upon the bushes. If the larva j appear in the autumn, powdered 
quicklime should be dug in during early winter; in the early spring the 
ground should be well hoed, and lime and soot applied ; spraying with Paris 
Green in September will kill the young larva?. 

" Rose Maggots " are the larva? of several small moths belonging to the 
Family Tortricidce, of which there are considerably over 300 British species, 
the best-known being the Green Oak Tortrix. Spraying with arsenate of 
lead will kill the larva? in the early stage, but the more general method is 
to employ the tedious process of picking out or pinching the grubs in the 
leaves, often after much damage has been done. 

The Frog-hopper, Frog-spit, or Cuckoo-spit Insect (PMlaenus (Aphrophora) 
spumaria) is the most common of the seven British " Frog-flies." It attacks 
the tender parts of plants, including the young shoots, leaves, and flower- 
buds, sucking the juices, and thereby weakening the whole plant. Roses 
are often badly attacked, especially when growing against a wall or fence. 
The perfect insect is found from July to October. It is about \ in. long ; 
the fore-wings are of a stout consistency and uniform in colour, and the 
hind-wings transparent. It can jump a considerable distance. The larva 
lives under a mass of spittle-like froth. Roses attacked should be well 
syringed with plain water to remove the spittle, and then sprayed with 
strong tobacco wash and soft-soap. For more hardy plants dilute paraffin 
emulsion may be syringed. 

The Apple Sucker (Psylla mail) somewhat resembles some of the Frog- 
hoppers in appearance and habits. It is a minute insect, but sometimes 

xliii

does considerable injury to the apple-crop by sucking away the juices from 
the stalks of blossoms and blossom-buds. Eggs are laid usually on the young 
shoots from September to early November. The larva? emerge in early spring, 
and at once enter the flower buds, there to suck the juices and prevent the 
formation of fruit. The perfect insect appears from the middle of May 
to the middle of .June. Early spraying with quassia wash has proved the 
most effectual remedy. 

The Apple Mussel Scale (Mylilaspis pomorum) belongs to one of the 
most destructive families among insects — the Coccida? or Bark-lice. The 
mussel-shaped scale is about J in. long, pale brown or grey, and in neglected 
orchards or gardens may be seen almost covering the trunk and branches. The 
wingless female lives under the scale, and lays a number of eggs, which hatch 
towards the end of May or the beginning of June. The larva becomes 
stationary after a few days, inserting its beak in the bark and sucking the 
juices. The scale gradually forms over it, and by the middle of August the 
female louse has laid a mass of eggs, there to remain till the spring under 
the dead body of the parent. The bark of trunk and branches should be 
scraped in winter, and then washed or sprayed with caustic alkali wash. 

Several other injurious insects will be dealt with under the heading of 
" Galls."

CHAPTER II 
USEFUL INSECTS 

It is well to remember that insects are not all harmful. On the contrary 
many plants have become dependent on insect agency for the perpetuation 
of the species, and this useful work is especially carried on by Bees, 
Butterflies, and Moths. But besides this, there are many insects which 
are indirectly beneficial by reason of their carnivorous habits, being either 
predatory or parasitic species living upon injurous forms. Were it not for 
their presence in the enemy's camp certain insect scourges would often 
get beyond human control. We will endeavour to point out a few of 
the more important useful species in the hope that it may induce cultivators 
to pause before they contract the habit of killing every creature that 
creeps, crawls, runs or flies. 

The Order Coleoptera furnishes several examples of useful insects. 

The Green Tiger Beetle (Citindela campestris) is a voracious creature 

both in the larval stage and when it becomes a perfect insect. It inhabits 

bare banks and sandy heaths, preying indiscriminately on other insects, 

often mounting upon the wing with the rapidity of a blue-bottle fly. It 

measures i in. or more in length, and is of a fine green colour, glossed 

with coppery red, and having five yellowish-white spots on the margin of 

each elytron, and another towards the middle. It is one of the most 

beautiful of British beetles. The larva lives in a cylindrical hole in the 

sandy soil, lying in ambush at the entrance with jaws expanded ready 

to seize its prey. The excavation is nearly perpendicular at the mouth, 

and the grub anchors itself to the side by means of two strong fleshy 

tubercles rising from a hump on its back near the tail. When about to 

pupate the grub seals the entrance and retires to the bottom of the hole. 

The Bombardier or Artillery Beetle {Brachinus eocplodens) has the head 

xlv 



TREES AND SHRUBS 

and thorax dull red, and the elytra blue. It is about \ in. long, and is 
found under stones in the vicinity of river-banks or the seashore. If 
alarmed or molested it discharges a slightly acid fluid, which immediately 
volatilises into smoke, each discharge being accompanied by a slight ex- 
plosion. Like the first species it is carnivorous in its habits. 

The Violet Ground Heetle {Carabus violaceus) is one of the commonest 
and largest of its genus, and is frequently found in gardens, hiding under 
stones or clods of earth. It sometimes exceeds an inch in length, and is 
deep violet in colour, with the margins of the elytra and thorax a rich 
burnished golden-violet. In common with the rest of its genus it has 
only rudimentary wings, the elytra being soldered together, and not used 
for flying. It runs swiftly over the ground, preying on other insects, 
and is a voracious creature both as a larva and a perfect beetle. When 
handled it emits from its mouth a blackish fluid which stains the fingers, 
and has a disagreeable odour. 

The Devil's Coach-horse, or Fetid Rove Beetle (Ocypus olem) belongs to 

the group of beetles known as Cocktails, so named from their habit of bending 

their bodies upwards when alarmed. This species is dull, dead black in 

colour, with very small elytra, and a long abdomen; two yellow tubercles at 

the end of the tail exude a secretion with a very objectionable odour. The 

beetle is an inch or more in length and very ferocious in aspect. It is 

common in gardens, and sometimes finds its way into houses. It will feed 

on carrion if procurable, but will attack and kill any insect which may come 

in its way, thus doing much good in gardens, and for this reason should 

never be destroyed. It is predacious both in the larval and perfect stages. 

Its eggs are r \, in. in length, being larger than those of any other British 

insect. It may be found throughout the year, except in May, when it 

pupates, but is most common in autumn. It flies with great rapidity, and 

runs swiftly over the ground ; hence its generic name (Gr. okus, swift, potis, 

a foot) ; its specific name referring to its evil-smelling secretion (L. olens, 

stinking). 

The Glow-worm (Lampyris noctiluca) belongs to the group of Soft-skinned 

xlvi 



/ 



USEFUL INSECTS 

beetles, the body being soft and flexible, and covered with a yellowish-grey 
down. The female has neither wings nor elytra, and has the power of emitting 
a strong phosphorescent light from the underside of the last three segments 
of the body. The male has well-developed wings and elytra, and emits only 
two tiny spots of light. The larva greatly resembles the perfect female, and 
does great service for the agriculturalist in attacking and devouring snails. 
During April or May the larva pupates, and the perfect insect appears in 
a fortnight or a little more. 

The Seven-spot Lady-bird (Coccinella septempunctata) is a great friend of 
the horticulturalist and agriculturalist, waging incessant war on the aphides, 
preserving for the use of man much which would otherwise be lost. The 
perfect insect has a black head and thorax, and red elytra usually bearing 
seven black spots, three on each elytron, and one near the base of the suture. 
The larva? are slaty and yellow, with black spots and hairy tubercles down 
the back, mixed with orange spots. They are popularly known as " niggers," 
and are exceedingly voracious, soon clearing a plant of aphides, literally by 
the thousand. So serviceable are they that they should never be disturbed. 
When full-fed they attach themselves to a twig or leaf by the end of the 
tail, and hang downwards, and the pupa? remain in the larval skin till 
changing into the perfect form. The disagreeable odour attached to the 
Lady-birds is connected with a yellowish liquid secreted from the joints of 
the limbs. 

The Two-spot Ladybird {Coccinella bipunctata) is another common species. 
The wing-cases are usually scarlet, bearing a black spot on each, but the 
colouring varies considerably from red and black to entirely black. 

The Sun Beetles (Ptcrostichus) number more than twenty species. They 
are very varied in colour, generally green, bronze, or bluish-black, the elytra 
being marked with regular stria?. They are very voracious, feeding on a 
large number of insects, darting swiftly over the ground when in quest 
of food. 

The Lacewing Fly (Chrysopa vulgaris) is one of man's best friends in 

the garden and orchard. The Hy is a delicate and beautiful insect, not 

xlvii 



TREES AND SHRUBS 

easily mistaken for any other species. Its body, head, and thorax are leaf- 
green : its eyes golden-green, large and conspicuous; and its wings wide, 
thin, gauzy, and glossed with changing hues of green and pink. It flies 
chiefly at night, and in the daytime may be seen at rest, with the wings 
pressed against the sides of the body. It possesses an evil odour, which 
attaches itself strongly to the finger that crushes it. The larva is extremely 
predacious, feeding voraciously on the aphides, covering itself with the emptied 
bodies of its victims as a protection. It pupates in a cocoon of extremely 
tough silk. The eggs are deposited on leaves, each being fixed to the end 
of a slender stalk about I in. long. They are pure white, and bear a re- 
semblance to the capsules of certain mosses. 

The Ichneumon Flies, of which there are probably over 2000 species in 
England, are of inestimable benefit to man, their chief function in the 
economy of nature being the maintenance of a balance amongst the various 
insect tribes. They are parasitic insects, belonging to the Order Hymenoptera, 
being provided with four wings, and the female being furnished with a sharp 
ovipositor. Many of them puncture the bodies of caterpillars, depositing an 
egg in each wound. The larvas, when hatched, devour the caterpillar alive, 
feeding on the soft but less vital parts of the host, and when full-grown 
quit the body of their victim, frequently forming their cocoons around it. 
Almost every species of caterpillar, grub, aphis, or other form of insect 
life, has one or more parasites which keep it in check. One of the species 
most frequently seen at work is Microgaster glomeratus, which lays from 
thirty to sixty eggs in a single caterpillar of the Large Cabbage White 
Butterfly. When about to pupate, the larvas gnaw their Avay out, and 
each spins a yellow silken cocoon, generally beside the empty skin of the 
caterpillar or upon its surface. 

The Chalcidkke are a family of Ichneumons, for the most part exceed- 
ingly small, and many being parasitic upon other parasites. Some deposit 
their eggs in various galls, where they feed upon the rightful inhabitants. 
Others work havoc among the aphides. 

The Proctotrupida?, a family of minute Ichneumons, comprise some of 

xlviii 






USEFUL INSECTS 

the smallest known Hymenoptera. They deposit their eggs in the eggs of 
other insects, particularly those of moths and butterflies, and are so minute 
that a single butterfly's egg will suffice for the support of several ichneumon 
larva?. By this means many eggs of the Lepidoptera must be destroyed, 
and our gardens and crops are thus protected by insects scarcely visible to 
the naked eye. 

The Hover Flies or Hawk Flies (Syrphidce), belong to the Diptera, in- 
sects possessing only two wings. They have a peculiar habit of hovering 
in the air, darting away like an arrow when disturbed, and hovering 
again at the end of their flight. They are common from spring to autumn, 
but more especially numerous from July to September. In appearance 
many resemble bees or wasps, but may be known by the manner of their 
flight and the number of the wings. 

The female fly deposits a single white egg in a colony of aphides, and 
the leech-like larva feeds ravenously upon them, sucking the juices and 
rejecting the empty skins. It is said that a hungry larva will devour a 
hundred aphides in an hour. When full-fed the maggot fixes itself to a 
leaf, stem, or other object by the tail, making the attachment by means of 
a sticky excretion. The pupa is developed within the larval skin, and in a 
few days the perfect fly emerges. 

Syrphus (Scctva) pyrastri is a fine species of Hawk-fly, whose larva may 
be found feeding on the aphides infesting Rose-trees. The insect is blackish- 
blue, with a whitish-grey down ; usually there are on each side of the abdomen 
three short bands varying from white to golden yellow. 

Another typical species is Syrphus lucorum. It is a pretty insect, somewhat 
variable in colour and the extent of its markings, but its general colour is black, 
the thorax being covered with brown hairs, and the base of the abdomen with 
golden down. 

Many of the genus Volucella are hairy species, strikingly like wasps and 
bees. Their larva? are short maggots with pointed tubercles on the seg- 
ments, living in the nests of wasps and bees, where they act as scavengers 

or feed on the larvae of their hosts. 

xlix f 



TREES AND SHRUBS 

In the great family of Muscidce, to which the House-fly and Blow-fly 
belong, we have a genus which consists of flies in some respects resembling 
the Ichneumons. Nearly two hundred British species have been described. 

One of the best known is Tacltina ferox. This species has the head 
tinged with grey : and the abdomen is yellowish, shining like horn, and 
black along the middle. The female lays her eggs upon the bodies of 
various caterpillars, and the young larva 1 penetrate into the body of the 
caterpillar, and feed upon the fatty tissues. Not only are the caterpillars 
of Butterflies and Moths attacked, but various species are known to infest 
the larva 1 of some Coleoptera. Hymenoptera. and even the bodies of spiders. 

The species Tachina grossa is so large and hairy that it might be easily 
mistaken for a black humble-bee. Its body measures J in. in length, and 
the wings have an expanse of 1| in. 

"We will conclude this brief review of some of the gardener's friends with 
a mere reference to one which he would scarcely care to encourage, but which, 
nevertheless, does him good service in keeping down the number of his enemies. 
It is the Hornet (J^espa crabro), the largest and most formidable of British 
wasps. The queen may measure 11 in. in length, and the wings may expand 
over 2 ins., but many of the workers are no bigger than the common wasp. 
The nest is usually built in outhouses or the hollows of trees. The food of 
the Hornet consists of other insects, and is largely composed of wasps.

CHAPTER III 
GALLS 

The study of galls and gall-producers is a fascinating one, and may be 
pursued at all seasons of the year. The British galls number nearly 300, 
and occur on all parts of plants. They are in most cases the result of 
insect agency, but some are due to the presence of nematoid worms within 
the tissues of the plants, and yet others are the result of attacks by fungi. 
No plants are more susceptible to galls than are the various species of Oak, 
and of the many kinds of oak-galls which have been described the greater 
number are produced by gall-wasps, insects belonging to the Cynipidae, a 
family of the Hymenoptera. A wonderful feature connected with the life- 
history of these gall-producers is the phenomenon of alternating generations, 
in which we have an insect producing an offspring, which at no time re- 
sembles its parent, but which, on the other hand, itself brings forth a 
progeny, which returns in its form and nature to the parent insect, so that 
the latter does not meet with its resemblance in its own brood, but in 
another generation. The two generations produce galls of very different 
character. One generation consists of females only, the other includes both 
males and females. We will now call attention to a few of the more 
common and interesting oak-galls, and give examples of this strange re- 
lationship. 

The Cherry Gall (Dryophanta scutellaris) is found on the under-surface 
of the leaf, attached to the midrib and its offshoots. As its name implies, 
it resembles a cherry in size, form, and colour, having a diameter of about 
f in., and being yellow, yellowish-green, pale-green or rose-coloured. It is 
found from July to October, and the imago emerges during the autumn and 
winter. It is the largest and most brightly coloured of the leaf-galls. The 

alternate sexual generation is found in the next species. 

li fi 



TREES AND SHRUBS 

The Purple Velvet-Bud Gall (Spathegaster Taschenbergi). This is a dainty 
little violet or purple gall found in dormant adventitious buds of the bark 
and small twigs. It may be sought for in April or May, and best on sunny 
days, but is not common. The imago emerges in May or June. 

The Cupped Spangle Gall {Neuroterus f'umipennis) is found on the under- 
surface of the leaf, and much resembles the Common Spangle, but is 
slightly smaller, being J in. in diameter. The prevailing colour is rose- 
madder, this being due to the presence of numerous microscopic stellate 
hairs. Nearly 500 of these galls have been counted on a single leaf. They 
may be found from July to September, and the imago emerges in the 
following May. The alternate sexual generation is seen in 

The Hairy Pea Gall {Spathegaster tricolor). This forms a conglomerated 
mass of 15-20 pea-like excrescences on the underside of the leaf, being most 
frequently found on scrub-oak bushes, and stunted, and hedge-trimmed 
growth along road-side banks. It is white, pale green, or yellow in colour. 
It may be seen during the summer (May to August), and the imago emerges 
in July. 

The Common Spangle Gall (Neuroterus lenticularis) is the largest and 
most abundant of the lenticular galls. It is found from July to October, 
scattered all over the under-surface of the leaf. It is greenish-yellow, 
covered with crimson or reddish hairs, and measures about \ in. in diameter. 
The imago emerges during March and April. The alternate sexual gene- 
ration is 

The Currant Gall (Spathegaster baccarum), which is found on the stam- 

inate catkins, and on leaves. It consists of a sappy and soft cellular tissue 

containing an abundance of a whitish, tasteless fluid, and when growing on a 

catkin peduncle the aggregation much resembles a "string" of red currants, 

the galls being generally suffused with pink, or spotted or striped with red. 

It is the most common of the globular galls, and may be found in June. 

The imago emerges during June, the entire metamorphosis occupying less 

than two weeks. 

The Silk-Button Spangle Gall (Neuroterus numismatis) is perhaps the 

lii 






GALLS 

most beautiful of the lenticular galls, and one of the most abundant, nearly 
700 having been counted on a single leaf, covering practically the whole of 
the under-surface. It appears as a small flat disc, about -J- in. in diameter, 
the prevailing colours being golden yellow, bright ochre, and golden brown. 
It is common from August to October, and the imago emerges during 
March or April, earlier than those of any other leaf gall. The alternate 
sexual generation is seen in 

The Blister Gall (Spathegaster vesicatriv). This, as its name implies, takes 
the form of a small blister in the blade of the leaf. It may be found from 
May to October, but is not easy to detect. 

The Oak Apple {Term terminals) is, on the other hand, familiar to every 
country school-boy, and is largely in evidence on the 29th of May, the day 
of all others most closely associated witli "King Charles's Apple." It is 
usually developed from a terminal bud, but those from axillary buds are 
also of very frequent occurrence. It is yellowish-white, suffused with pink 
and red, and measures 1-2 ins. in diameter. Growth is complete by the 
end of June, but the "apple" may be found throughout the year. The 
imagines emerge during June and July. The alternate asexual generation is 
found in 

The Root Gall (Biorhiza aptera). This usually takes the form of a con- 
glomerated cluster on the roots and rootlets, and may measure H in. in 
diameter. It may be pink, red, or of varying shades of brown. Growth is 
complete by the end of October, and the imago emerges during the winter 
or spring. The females are mostly wingless. After leaving the gall the 
female creeps up the bole of the tree, along a limb, and selecting a terminal 
bud, bores holes with her ovipositor, the ova being pushed down the holes 
till they form a mass at the base of the bud. The resulting gall is the Oak 
Apple. 

The Marble Gall, or Oak Marble, is the work of Cynips Kollari. It is 
one of the most familiar galls, and is often erroneously spoken of as the 
oak-apple. It is usually noticed when the hedgerows are leafless, and then 

has much the appearance of marble, being spherical, and brown in colour. 

liii 



TREES AND SHRUBS 

They may l>e found growing either singly, in groups of 3-0, each being 

perfect in shape, or in conglomerate clusters consisting of several galls more 

or less fused together. They are not usually borne by fully developed trees. 

The ova are deposited in a leaf-bud towards the end of September or early 

in October. A small swelling is formed on the twig, but does not increase 

much in size till the following April or May. Growth then continues, and 

by the end of September the gall has become firm and hard, and is of a 

yellowish-brown or reddish-brown hue. It may remain attached to the twig 

for several years. The question of an alternate sexual generation is still an 

open one, but it has been considered likely that it will be found in the 

Turkey Oak Hud Gall (Andricus circulans). 

The species of galls above mentioned are some of the easiest to find, but 

there are many more of extreme interest, and the reader who wishes to 

pursue the study may be referred to Connold's " British Oak Galls," a work 

to which we are indebted for much recent information. 

The Robin's Pincushion, Rose Bedeguar or Moss-gall, is the work of 

Rhodites roses, an insect belonging to the Cynipidae. The greenish, pink, 

or crimson gall is formed by ova being deposited in a leaf-bud, each egg 

becoming surrounded with layers of sap, and ultimately making a mass of 

30-45 cells concealed beneath a covering of many-branched fibres. The 

globular conglomeration of cells may reach nearly 2 ins. in diam. The 

larvae pupate in the gall, and the imagines emerge during June. 

Rhodites eglanteriae forms small, smooth, globular galls on the leaves and 

petioles of Dog Rose and Sweet Briar. They are attached by a delicate 

pedicel, and are unilocular and unilarval. They may be found from July 

till October. The larva pupates in the gall, and the imago emerges during 

the following spring. 

Horse-bean Galls, so familiar on the edges, and on either side of the 

midrib of willows, is caused by a Saw-fly (Nematus galMcola). The gall is 

equal in proportion on both surfaces of the leaf, and is green, suffused with 

red, pink, or purple. The larvae, when full fed, generally burrow into the 

soil, and there pupate. The imagines, which emerge in August and Sep- 

liv 






GALLS 

tember, lay eggs in early autumn, and the larva 1 pass the winter within 
the gall, the resulting brood appearing in April or May. 

Of the many thousands of Lepidoptera (Butterflies and Moths) whose larva 
feed in or on plants, only about half-a-dozen are known to produce galls, and 
of these two only need be mentioned here. 

Hedya aceriana is a dull cream-coloured moth with the fore-wings expanding 
T 7 ^ of an inch, and appears in July or August. The dirty-brown larva eats 
its way into the young shoots of poplars, and the irritation causes an unsightly 
swelling. The gall may be found from June to August. 

The Resin-gall Moth (Retima resinella) belongs to a group of the Tortricida 
which inflict damage on Scots Pine and other Conifers. The egg is laid among 
the buds at the extremity of a young shoot, and the larva feeds upon, and 
bores into the stem, causing an exudation of resin not unlike a half walnut 
in form, and somewhere near the size. The larva pupates in the gall of resin, 
and the imago emerges in March. The fore-wings measure fy \\ in. and 
are dark blackish-grey with silvery streaks. The moth is mostly confined to 
Scotland and the north of England. All shoots showing signs of attack 
should be removed and burned. 

The Aphides or Plant-lice belong to the Homoptera, in which the fore- 
wings are uniform in structure from base to apex. They are minute in size, 
soft-bodied, and generally long-legged ; the mouth is provided with a curious 
beak or rostrum for sucking the juices of plants, and nearly every plant 
has its own peculiar Aphis. Many kinds secrete " honey-dew " from two 
cornicles or honey-tubes at the end of the abdomen, and this, falling on 
the leaves, prevents respiration. Their rate of increase is marvellous, and 
reproduction is carried on in two ways. In the spring the wingless females 
produce living young, which soon mature and produce other wingless females, 
the process continuing with gi-eat rapidity till the plant may become completely 
covered. At the end of the season males and females both are produced, 
and sexual reproduction takes place, the eggs being laid upon the plant, 
and lying dormant through the winter. In the spring the eggs hatch out, 

and the cycle is again begun. The irritation set up in the plant by the action 

lv 



TREES AND SHRUBS 

of the aphides often causes abnormal growths, and it is some of these with 
which we are concerned in this chapter. 

The Woolly Aphis or Apple Root Louse, often called American Blight 
(Schizoneura lanigera), causes large warty excrescences on every part of the 
trunk and limbs of Apple-trees. These swellings are the result of the con- 
tinuous punctures of the rostra of the aphides, the sap accumulating into 
soft pulpy masses which harden in winter, cracking in all directions on the 
surface, and producing scabby hypertrophies or "canker-like" growths which 
often attain large dimensions. The presence of the aphides in summer is 
readily apparent from the presence of a white cottony substance formed as 
an excretion in the back of both young and mature females. The wool some- 
times hangs in festoons from the trees, and, being blown about by the wind, 
acts as a means of dispersal of the pest, but the infection is most frequently 
spread by means of nursery stock. This species is not provided with cornicles, 
and does not produce honey-dew. The wingless females are purplish-brown, 
and the lice or larva? are dull yellowish to reddish in colour. The best pre- 
ventative of the pest is clean cultivation, the trunks and boughs being kept 
free from lichens and moss, and no rank grass being allowed to grow beneath. 
In winter the trees may be cleansed of the vegetal encumbrances with a 
caustic alkali wash, and the trunks may be lime-washed after the removal 
of all rough bark. 

The Currant Blister Aphis (I.) (Rhopalosiphum ribis) causes convex or 
concave blisters on the foliage of Currants, red, black, and white, but especially 
the first. The leaves attacked shrivel away, and the fruit often falls, owing 
to loss of sap, long before the leaves die. The wingless viviparous female, or 
" Mother Queen," is shiny green, mottled with darker green, and the cornicles 
are green. The lice turn to pupa?, from which arise winged, viviparous females, 
yellowish-green in colour, with black head. Later on the egg-laying female 
deposits eggs on the twigs, and these hatch in the following spring. This 
aphis also attacks the Gooseberry, and has been found on the Guelder Rose. 

The Currant Blister Aphis (II.) (Myzus ribis) is distinguished from the 

former by differences in colour in the various stages. The wingless female 

lvi 






GALLS 

is shiny yellowish-green, with dark green mottlings ; and the cornicles are 
pale green. The winged viviparous females are bright green, with pale 
olive head. This species often causes the leaves at the apex of the shoots 
to curl and twist up. It attacks Gooseberries as well as Currants. Early 
spraying with paraffin emulsion is the best treatment, but little can be done 
when once the lice have got a hold. 

The Elm Aphis {Sckizoneura ulmi), frequently rolls, blisters, and distorts 
the foliage of Elms. The galled leaves may be found from June to October. 
Usually only one half of the leaf is attacked, curling downwards and under, 
forming a roll within which the life stages are passed, as in the case of the 
Currant Aphis. The unaffected part of the leaf does not appear to suffer 
much from the attack, but the galled portion is gradually denuded of all 
sap, and turns to a yellowish-green, and finally to a pale ashy grey. 

Pemphigus bursarius, or Aphis bursaria, forms an attractive gall on the 
petioles of Black Poplar, and sometimes the Lombardy Poplar. The gall 
consists of a pear-shaped or oval purse-like swelling, green in colour, suffused 
with pink. It is usually % in. long and about 1\ in. in girth. It is very 
plentiful from July to September, and on badly infected trees some branches 
may have 25 per cent, of their leaves attacked. The queen aphis 
punctures the petiole of the leaf, and the sap exuding, gradually surrounds, 
and finally encloses her, and the work of reproduction goes on. The winged 
aphides make their exit through a small opening at the apex of the gall. 

The Pine-apple Gall, so common on young trees of Norway Spruce Fir, 
is the work of an Aphis {Adelges (Chermes) abietis). The queen emerges in 
June, hybernates through the winter, and in the following spring punctures 
the shoot at the axils of the young leaves, causing their bases to thicken 
by an accumulation of sap. The thickened bases form a kind of false cone 
in which innumerable eggs are laid, the resulting colony numbering perhaps 
1800-2000 insects. The dry galls may remain on the trees for several years 
before final disintegration, the infected shoots being often distorted and some- 
times killed. 

The order of Diptera includes over a hundred gall-making insects, usually 

lvii 



TREES AND SHRUBS 

called Gall-gnats and Gall-midges, and the greater number of these belong 
to the sub-genus Cecidomyia. 

Cecidomyia cratcegi causes a cluster or rosette of 8-40 deformed leaves 
at the extremity of a shoot on the Hawthorn. The leaflets in the centre 
are stunted in growth, curl inwards, and provide shelter and food for 
numerous larva 1 during the summer months. The larvae pupate in the 
ground, and the gall-flies emerge in the spring. 

Kosette Galls are to be found on several kinds of Willows, and are the 
work of Cecidomyia rosaria. The single larva feeds upon the end of the 
shoot, preventing its further growth, and a rosette is formed, consisting of 
30-60 leaves in all stages of development, the outer ones occasionally 
being woody. The larva pupates in the gall, and the fly emerges in the 
spring. 

Cecidomyia marginem-torquens causes the margins of the leaves of Osiers 
to roll along the under-surface towards the mid-rib. The margins become 
variously coloured, yellow, red, purple, and chocolate-brown being the pre- 
vailing tints. The larva? feed in the gall from June to October, pupate in the 
ground during the winter, and the flies emerge in spring. 

Cecidomyia salicis forms peculiar lemon-shaped swellings on the twigs 
of Grey Sallow {Salix cinerea), and sometimes the Round-eared Sallow 
{Salix aarita). The galls are nearly an inch long, and about h in. in diam. 
The larvae, from three to thirty in number, pupate in the gall, and the imagines 
emerge in May, leaving about half of the puparium projecting from the hole, 
after the manner of the Goat Moth when emerging from its cocoon. 

The Gall-mites belonging to the Order Acarina are microscopic creatures 
which live on plants, by preference in the bud, and produce galls of various 
descriptions. 

The Black-Currant Mite {Eriophyes (Phytoptus) ribis) causes the buds 

to swell unnaturally, so that they produce neither leaves nor fruit. From 

some infested buds a few stunted leaves may come forth, but they fall in 

the early summer, and no blossoms are formed. The mite is indistinguishable 

with the naked eye, but can be seen with a good pocket lens. The body is 

lviii 






GALLS 

cylindrical, and consists of about 70 rings. Eggs are found in the buds 
nearly all the year round. The mites stray about the shoots when the buds 
shrivel up, and later find their way into the embryonic buds. In January 
the buds contain adults and eggs, in February the eggs are in abundance, 
by March there are hundreds of young mites and several adults, and by 
April there are mites in all stages. In June they may travel from the old 
buds to the new, and by July there are eggs, young and adults in the 
young buds, thus continuing the infestation for the next season, and making 
remedial measures of little avail. Infested bushes should be pruned very 
hard, and all cuttings burned. The best plan to adopt is to cultivate from 
clean stock, carefully examining all new bushes, and rejecting any which 
show any indication of unnaturally swollen buds. 

" Witch-knots," " Witches' Brooms," and " Rooks' Nests " are names 
given to large bunches of distorted twigs often to be seen on the Birch. 
They vary in size from a few inches to many feet in circumference. They 
are caused by a gall-mite {Eriophyes rudis), which lives in the buds, absorbing 
nourishment, and preventing proper development. The growth of the twig 
is arrested, and as the new buds appear, they are attacked by the mites and 
rendered abortive. The mites increase in numbers very rapidly, and when 
the work of thousands is concentrated at one spot it causes the many twigs 
to grow outwards in all directions, while the common centre becomes a hard, 
solid, and woody core. In cases where the mites are distributed along the 
branches a dense bushy tangle of long and slender twigs is formed. Apparently 
the presence of these galls does little or no harm to the general growth and 
development of the tree. Similar growths are caused by a Fungus. 

Eriophyes (Phytoptus) Icevis causes variously-coloured pimple-like galls 
on the upper surface of the leaves of Alder. They are green, yellow, red, 
purple, or brown, and may number as many as 400 on a leaf. When 
numerous they cause the leaf to curl and fold up in a very distorted manner. 

" Nail-galls " on the foliage of Limes are the work of Eriophyes tilice (typicus), 

They are of varying shades of greenish-yellow, red, crimson, purple, and brown^ 

and have the appearance of tacks projecting through the upper surface of 

lix 



TREES AND SHRUBS 

the leaf. They are hollow, the interior containing a quantity of long hairs, 
giving shelter to innumerable mites. A single leaf may support as many 
as 1.50 of these galls. 

The leaves of the Common Maple are often literally covered with smooth, 
semi-globular pimples, the work of a gall-mite] {JEriophyes macrorhyneus). At 
first greenish-yellow, the galls pass through shades of yellow, orange-yellow, 
red, crimson, and purple, and finally become brown. Many leaves will support 
400-500 galls ; some may even bear as many as 800, and a somewhat large 
leaf has been crowded with nearly 1400. 

The Maple foliage is also attacked by a somewhat similar, but larger 
gall, made by the mite Eriopln/es macrochelus. A leaf may have 50-200 
of these globular galls, which vary considerably in shape and appearance, 
being usually green, orange-yellow, red, or brown in colour. Occasionally 
they may be seen on the underside of the leaf, but are most often situated 
on the upper surface.

CHAPTER IV 
FUNGOID PESTS 

INTRODUCTION. In the treatment of fungoid pests it is essential to 
know that parasitic fungi may be placed in two groups, each with a different 
mode of development, and each necessitating a different method for their 
prevention or cure. The first, or epiphytal group, includes those fungi which 
establish themselves on the surface of leaves, stems, or other green parts of 
living plants, their whole career being external and superficial. Many of these 
can be held in check or destroyed by powdering or spraying. The Hop Mildew 
and Rose Mildew are familiar examples of this class, the first being kept in 
check by the application of sulphur, and the second by spraying with potassium 
sulphide solution. In the early stages of attack the mildews present themselves 
as patches of white mould consisting of a stratum of delicate interwoven threads, 
forming a mycelium, from which arise fertile threads producing myriads of 
spores to carry on the infection. Later in the season other spores are 
formed which will rest during the winter, and germinate in the following 
spring. 

The second group of parasites are endophytal, originating in the tissues 
of the host-plants, and manifesting themselves externally only when the 
damage is beyond control. In these cases all efforts must be directed towards 
destroying the spores, and preventing the future infection of healthy plants. 
The " rot moulds " belong to this group, and are among the most devastating 
of fungoid pests. The mature mould, when it appears on the surface, pro- 
duces a profusion of spores, or conidia. From these there issue minute 
zoospores provided with delicate cilia enabling them to swim in any thin 
film of moisture. If this be on a leaf, the zoospore may enter one of the 
stomata, and give rise to a mycelium within the tissues. From this there 

issue fertile threads, reaching the surface through the stomata, to carry on 

lxi g 



TREES AND SHRUBS 

the work of reproduction through conidia as hefore. Resting spores are 
produced within the tissues, and carry on the attack anew in the spring. 

A large and important group of endophytes is that known as the 
Uredines, in which there are three distinct stages of development, each 
of which may he considered as a fungoid disease. 

The first stage is known as the "cluster cups," or aecidium form, and 
consists of clusters of little cups, partly imbedded in the substance of the 
leaf or twig of the host-plant. The margin is usually white and fringed, 
and the interior filled with orange subglobose spores, termed a?cidiospores. 
A species, exceedingly common in spring, may be found on the under- 
surface of the leaves of the Lesser Celandine or Figwort {Ranunculus ficaria). 
Less frequently it occurs on other species of Ranunculus, and is known as 
the Crowfoot Cluster-cups. The " cluster cups " form of parasitic fungus is 
found on many trees and shrubs. 

The second stage is reached in the summer, when on the same leaves, 
or others, there are developed small brownish pustules, which at length split 
irregularly, exposing a mass of minute brownish spores, each borne on a 
short thread. These powdery spores, known as uredospores, constitute the 
" rusts " which attack many plants. 

The third stage consists of teleutospores. These are produced in pustules 

similar to those of the second stage, and may sometimes be found mixed 

with them. They are more or less elongated, being supported on hyaline 

threads, and divided across the middle into two cells. Each of these cells 

may give rise to a germ tube or promycelium, and the apical cell may also 

produce secondary spores by cell-division. These last are eligible for the 

production of mycelium which on entering a new host plant will commence 

the cycle again. ^Ecidiospores, uredospores, and teleutospores may or may 

not be all produced on the same plant, but there are many variations, and 

the cycle is not always complete. Mycologists are divided in opinion, and 

there is still much to be learned before many of these life-histories are fully 

understood. 

Having given this brief sketch of their various phases, we will turn our 

lxii 



FUNGOID PESTS 

attention to some of the more common of these Fungoid Pests, and will 
group them under four heads, viz. — 1. Roses ; 2. Orchard and Fruit Garden ; 
3. Ornamental Shrubs; 4. Forest Trees. 



I. DISEASES OF ROSES. 

Rose Mildew, Sphcerotheca pannosa, is undoubtedly the most prevalent 
and destructive of all Rose pests. Its dirty-white felted mycelium of inter- 
woven threads clothes the leaves, shoots and flower-stalks of all kinds of 
Roses. The mycelium sends up short branches, which produce conidia attached 
to each other in a chain. They are produced in rapid succession during the 
summer months, and, unless kept in check by frequent spraying or the use 
of sulphur, will soon give rise to an epidemic beyond all control. No fungoid 
disease can be cured by spraying, but it may be prevented from extending, 
by killing the spores which alight on the leaves. 

As the season advances winter spores are produced. They consist of 
small dark brown globose receptacles scattered about upon the whitish 
mycelium. When mature each receptacle encloses a single globose trans- 
parent sac, or ascus, containing numerous spores which will germinate in 
the following spring. This winter fruit is found in the mycelium growing 
on the young wood, or rarely on the fruit, but not on the leaves. It is 
essential that every patch of mycelium should be carefully scraped off and 
burned, doing this early in the season, before the spores have a chance 
of falling to the ground. 

Rose Rust, Uredo Bosce, occurs during the summer on the leaves, petioles, 
and stems of wild and cultivated Roses, bursting through the cuticle as 
an orange-coloured powder. The patches on the underside of the leaves are 
small, or may coalesce to form a larger patch, while on the stems they 
may extend to an inch in length. When the rust disappears wounds or 
canker spots remain, which favour the growth of other fungi. 

The rust patches on the wood may be treated with a solution of equal 

parts of methylated spirit and water, rubbing in with a piece of sponge.

TREES AND SHRUBS 

Plants which have been attacked the previous season should be sprayed 
with a solution of potassium sulphide, or copper sulphate just before the 
leaves expand. 

Hose Brand, Phragmidium mbcorticium, is the advanced stage of the 
Kose Rust. It forms minute blackish projecting tufts on the under surface 
of the leaves, taking the place of the gradually disappearing Rust in autumn. 
Each point is a long and cylindrical teleutospore, of a very dark brown 
colour, divided transversely into 3-7 cells. In the spring they produce 
secondary spores which again give rise to the orange summer form. 

Preventive measures consist of collecting and burning all infected leaves, 
not only those that are dead and fallen, but any that remain on bushes that 
have been infected. 

Rose-leaf Rlack Blotch, Actinonema lioscv, is a common fungus, appearing 
as somewhat rounded spots on the foliage, being at first purplish, and then 
black. Radiating from the black spots are flexuous threads of a delicate 
mycelium, and scattered among them are small black conceptacles contain- 
ing sporules. The mycelium permeates the leaf tissues, causing premature 
defoliation. 

Badly diseased leaves should be removed from the bushes and burned, 
together with all diseased leaves lying on the ground. Spraying with potas- 
sium sulphide, early in the season, and continued at intervals has been recom- 
mended, but does not seem to have much effect when the disease has once 
gained a foothold. Dilute copper sulphate, and Eau Celeste or Blue Water 
are also used for spraying. 

Rose Leaf-spot or Leaf-scorch, Septoria Rosarwn, not only disfigures 
the leaves, but seriously weakens the plant through premature defoliation, 
badly diseased plants being often quite leafless by the end of July. The 
fungus appears as rounded spots on the upper surface of the leaf, yellowish- 
green at first, becoming pale brown later, and bordered by a dark purple 
ring. The brown patches usually fall out, leaving holes in the leaf, but 
they may remain fixed, and will sometimes be studded with minute black 

points, the perithecia or reproductive bodies of the fungus, containing thread- 

lxiv 






FUNGOID PESTS 

like sporules consisting of a chain of six cells. The disease is very prevalent 
on wild Roses and Brambles, and is difficult to eradicate. 

All diseased leaves should be collected and burned. Where the disease 
has existed the sulphate of copper solution may be used to drench the 
bushes and the surrounding ground. Spraying with " liver of sulphur " 
(potassium sulphide) should be done when the leaves are half grown, and 
repeated at intervals. 



II. DISEASES OF ORCHARD AND FRUIT GARDEN. 

We will next mention a few of the more common Fungoid Pests to be 
found in the Orchard and Fruit Garden, and for convenience of reference 
will place them in alphabetical order, without regard to any scientific classi- 
fication. 

Apple-leaf Spot, Septoria pyricola, occurs on the upper surface of the 
leaves of Apple and Pear. The substance of the leaf within the spot is 
killed by the mycelium and bleached, and the surface is dotted with minute 
black points. Each point is a tiny receptacle with a minute pore at the 
apex, out of which the fungus spores issue and spread themselves over the 
leaf. 

Apple-tree White Mould, Oidium farinosum, covers the young twigs and 
leaves of Apple trees with a mealy coating, causing the leaves to curl, and 
distorting the tender twigs, at the same time giving them the appearance 
of having been dusted with flour or powdered chalk. Fertile branches arise 
from the profuse mycelium, and give a continuous crop of conidia, causing 
the disease to rapidly spread. Dusting with "flowers of sulphur" is the 
most effectual treatment. 

Apple-tree Canker, Nectria ditissima, is the most frequent and destructive 

form of canker attacking Apple trees in this country. The fungus gains 

admission to the living tissues through a wound, and then spreads rapidly 

in the living bark, which becomes eaten away in patches, leaving the wood 

exposed, and in very young branches even the wood itself may be destroyed. 

lxv 



TREES AND SHRUBS 

Where the bark is destroyed all round the branch, the portion above the 
wound is at once killed. On older parts of the tree the fungus will often 
gain an entrance through a crack in the fork of a branch, and after becoming 
well established will travel up the branch and cause its destruction by burst- 
ing through the bark at different points along its course. If the cracks con- 
taining the fungus be examined in spring there will be seen minute red dots 
growing in clusters on a white mycelium. These smooth spherical dots are 
the perithecia or conceptacles, and contain a pulpy nucleus consisting of a 
great number of long cylindrical tubes, or asci, each enclosing a row of eight 
spores. On germinating these spores give rise to the summer stage of the 
fungus, which may be seen as minute white specks nestling in the crevices 
of the rugged bark surrounding the wounds. 

The white stage of the fungus can be killed by applying with a brush 
a solution of sulphate of iron — 1 lb. to a gallon of water. Young branches 
that are attacked should be cut off. In older branches the diseased parts 
should be cut away, and the cut surface carefully anointed with gas tar. 

The canker fungus is said also to attack Pear, Plum, Oak, Beech, Ash, 
Hazel, Alder, Maple, and Lime. 

Apricot Brown Rot, Monilia fructigena, attacks the fruit of Apple and 
Pear in England, and of Apricot, Peach, and Cherry in the United States 
of America. The disease appears as a discoloured brownish spot, soon followed 
by the growth of dull grey tufts arranged in irregular concentric rings. The 
tufts are composed of dense masses of spores arranged in long branched chains. 
Although most conspicuous on the fruit, the fungus usually attacks the leaves, 
forming thin, velvety, olive-green patches, and from these the spores are carried 
to the blossoms or young fruit. If allowed to follow its course undisturbed 
for some years, the fungus may attack and kill the young shoots. The in- 
fected fruit becomes dry and mummified, like a large mouldy Plum, and in 
the spring produces a copious supply of spores to carry on the disease. The 
second or ascigerous stage of the disease has been found in the United States 
growing abundantly on old half-buried peaches. 

All dead twigs and shrivelled fruit should be collected and burned during 

lxvi 






FUNGOID PESTS 

the winter, and the ground thoroughly drenched with a solution of sulphate 
of iron. The solution may also be used for spraying in January or early 
February, before the buds begin to swell. When the buds are expanding 
the trees may be sprayed with very weak Bordeaux mixture. 

Fruit-tree Pustule, Eutypella prunastri, is a fungoid disease which attacks 
young fruit-trees and nursery stock, Plum and Apple suffering most severely, 
and Peach, Apricot and Cherry to a less extent. It is often abundant on 
Wild Plum, Bullace, Blackthorn, &c. In the orchard it probably enters the 
tree through wounds made by pruning. In the first stage there is a drying 
up, browning, and shrivelling of the bark, and threads bearing conidia ooze 
out through minute elongated cracks. These are followed in the second 
season by larger transverse cracks or perithecia from which asci are produced, 
each containing eight sporidia. These are ripe in late spring or early summer, 
and carry on the infection. The fungus growing in the bark and cambium 
must ultimately kill the young tree. All diseased plants should be burned, 
and wounds on the stem should be coated with gas tar. 

Gooseberry Mildew, Microsphcera Grossitlarhc, forms white patches on 
both sides of the leaves, giving them the appearance of having been sprinkled 
with flour. The powder consists of myriads of spores or conidia, which, unless 
destroyed, will rapidly spread the infection. When the disease is severe the 
leaves die and fall early, hindering the development of the tree. Later in 
the season minute black points are seen among the mycelium. These are 
the globose receptacles, each furnished with 10-15 colourless radiating fibres, 
and containing 4-8 sacs, or asci, each enclosing four or five sporidia. 

Being an epiphyte, the disease may be checked by the application of 
sulphur, but the most effective treatment is spraying with a solution of 
potassium sulphide. All dead fallen leaves should be burned in winter, and 
the ground around the bushes should be well dug to bury stray spores. 

American Gooseberry Mildew, Sphcerotheca Mors-uvce, usually makes its 

appearance on the expanding leaf-buds, extending later on to the young 

wood and fruit. It has a cobwebby appearance, becoming white and powdery, 

and may be readily peeled off. In this country the fungus appears to be 

lxvii 



TREES AND SHRUBS 

mostly confined to the tips of the shoots, causing them to become brown 
and shrivelled. The life-history resembles that of the previous speeies. To 
combat the attack spray with potassium sulphide, one ounce to two gallons 
of water, repeating every ten days till the fruit is nearly mature. 

Peach-leaf Blister or "Curl," Exoascus deformans, causes the leaves to 
become blistered and contorted in various ways, presenting an appearance 
as though suffering from an attack of aphis. Such a case of distortion might 
well have been placed in the chapter on Galls, especially as the curling of 
the leaves is often accompanied by an abnormal swelling of the young 
shoots, but owing to the serious nature of the disease we have preferred to 
describe this and some few others as true Fungoid Pests. The fungus in 
this instance causes the under surface of the leaves, in the hollows of the 
blisters, to assume a hoary or frosted appearance, the interior being closely 
packed with cylindrical cells, or asci, containing sporidia, the whole being 
covered with a transparent membrane. 

Diseased or fallen leaves should be burned. The mycelium is perennial 
in the branches, following the young growth, producing the disease in 
the leaves each year, and preventing the ripening of the wood. Branches 
bearing diseased leaves should be pruned back beyond the point of in- 
fection. 

Pear-leaf Cluster-cups, Rasstelia cancellata, is a parasite which thickens 
Pear leaves at the infected spots by the internal growth of the mycelium, 
and the " cups " are flask-shaped brown bodies containing secidiospores. The 
cups, or peridia, split into numerous thread-like filaments, which for some 
time are united at the apex. The diseased leaves fall early in the autumn, 
resulting in a lack of reserve food for the following season, and if the attack 
occurs two or three years in succession, the tree will probably perish. All 
diseased leaves should be burned. By some authorities the Puccinia gene- 
ration of this disease is said to be found in the Savin Jelly-rust. 

Pear-leaf Blister, Exoascus bullatus, or Taphrina bullata, distorts the 

foliage in a similar manner to the "curl" on Peach leaves, but in this case 

the leaves remain flat. All blistered leaves should be burned, to check re-

FUNGOID PESTS 

production. In the case of young trees frequent spraying with dilute Bor- 
deaux mixture may be a preventive. 

Plum-tree Mildew, Podosphcera tridactyla, attacks the foliage of Plum 
and Cherry trees, and resembles the Gooseberry Mildew in appearance. The 
receptacles in the case of the Plum have usually six or seven radiating arms, 
while those of the Cherry have from eighteen to twenty of these appendages. 
The disease may be checked by the application of sulphur. 

Plum Pockets, Eccoascus Pruni, is a disease easily recognised by reason 
of the familiar " Bladder Plums " which are the result of the attack. These 
galled and swollen fruits, as well as Witches' Brooms, are frequently found 
on the Bullace, the fungus being known as Exoascus insititice. In the case 
of this tree the diseased fruits may attain dimensions three or four times 
larger than that of a normal-sized fruit. The mycelium is perennial in the 
twigs, and from these travels to the ovaries of the flowers, taking possession 
of the young fruit, diverting and absorbing the supplies of nutriment, pre- 
venting the formation of seed, and causing considerable malformation of the 
fruit. Growing from the mycelium are closely-packed cylindrical asci, each 
containing eight sporidia, which, escaping from the infected fruit, may carry 
on the disease. The diseased fruits, after going through various changes of 
colour, become shrivelled, and fall to the ground. All " pockets " should be 
collected and burned, and the branches may with advantage be cut back 
beyond the point of infection. 

Witches' Broom of Cherry is caused by the fungus Exoascus Cents/. The 
disease shows itself in the production of dense tufts of branches, growing 
apparently from a central point, very similar to those already described in 
the chapter on Galls, under the title of " Witch Knots." In the present 
case the fungus appears as a hoary bloom on the branches. The slender, 
club-shaped asci enclose nearly globose sporidia. The only known remedy 
is to cut out the disease tufts and burn them, so as to prevent propagation 
by spores.

Barberry Cluster-cups, Au-idium Berberidis, is a disease which attacks 
the Common Barberry. The cluster-cups are to be seen during the summer 
on the leaves, peduncles and fruit. They are rather elongated and packed 
closely side by side in sub-rotund or oval patches. The margin of the cups 
is white and toothed, and the interior is rilled with chains of globose orange- 
coloured spores. Some authorities consider this pest as one stage in the 
life-history of the Wheat mildew. 

Barberry Leaf Mildew, Microsphceria Berberidis, is a common pest of 
Berberis vulgaris, and resembles the Gooseberry Mildew in appearance. The 
globose receptacles are surrounded by a circle of about ten appendages, each 
beautifully forked in a dichotomous manner. Each receptacle encloses about 
six asci, and each ascus contains G-8 sporidia. The mildew may be checked 
by the application of sulphur. 

Ivy leaves are attacked by at least three species of Spot. Dotted about 
in the discoloured patches are small receptacles enclosing thread-like sporules. 

Leaf Sooty Mould, Capnodium Footii, is a very common black mould 
forming thin sooty spots on the leaves of many plants, and often to be seen 
on Holly, Ivy and Cherry Laurel. The creeping mycelium consists of colour- 
less or brownish threads, each divided into a chain of cells. The perithecia 
or receptacles are erect and bristle-like, and fringed at the mouth. All sooty 
leaves should be picked off and burned. 

Phillyrea Rust, Uredo PhiUyrece, is sometimes found on the leaves of 
Mock Privet, and takes the form of round, yellow pustules filled with orange- 
coloured uredospores, each with a thick hyaline outer coating. 

Rhododendron Galls are often to be seen on the leaves of Rhododendron. 

ferrugineum, and similar gall-like swellings are produced on Bay-Laurel. They 

are caused by a fungus, Exobasidiiuii Rhododendri. They vary in size from 

f in. to about f in., and are at first yellowish-green, becoming reddish later, 

and covered with a delicate bloom. The mycelium traverses the interior of 

the gall, and the " bloom " consists of the fungus fruit. The naked spores 

lxx 






FUNGOID PESTS 

are borne at the apices of stout erect spore-bearers called basidia, there being 
usually four basidiospores to each of the basidia. Diseased leaves should be 
burnt as soon as seen, in order to prevent the production of spores. 

Savin Jelly-rust, Gymnosporanginm Sabince, causes gouty swellings in the 
branches of the Savin (Juniperits Sabina). These swellings burst through as 
an orange-coloured gelatinous mass consisting of teleutospores. These are 
two-celled, and each cell may give rise to a thread-like promycelium which 
divides at the extremity into three or four cells, each producing a secondary 
spore. Some mycologists consider this disease to be a stage in the life of 
the Pear Cluster-cups, and strongly deprecate the growing of Savin bushes 
in the neighbourhood of Pear trees. 



IV. FUNGOID PESTS OF FOREST TREES. 

Ash-leaf Spot, Septoria Fraocini, affects almost every leaf if once it attacks 
a tree. It takes the form of irregular discoloured patches, sometimes covering 
the entire leaflet. The minute conceptacles are immersed in the substance 
of the leaf, and contain numerous cylindrical sporules. 

The Beech-tuft, A r miliaria mucida, is a handsome Toadstool which is often 
seen growing in clusters on the trunks and branches of old Beech trees. It 
is greyish-white in colour, with a slender stem 3-5 ins. long, and a hemi- 
spherical, flattened cap, 1-4 ins. in diameter. It is of a slimy character, but 
delicious when properly cooked. It is said to be a wound parasite, capable 
of attacking a healthy branch, causing death and decay. All wounds and cut 
branches should be protected with a coating of tar. The Agarics should be 
eaten or destroyed. 

Birch-leaf Rust, Melamspora betulina, is common from May to November. 

The pustules are of two kinds. Those which contain uredospores are pale 

orange, the spores being orange-yellow, and ovate. The teleutospores are 

pale yellow-brown, cylindrical, slightly wedge-shaped, and closely packed side 

by side, the pustules changing from yellow to brown, and finally becoming 

black.

TREES AND SHRUBS 

Birch-leaf Blotch, Dothidella betulina, appears as small hlotches containing 
white cavities or cells in which the fruit of the fungus is developed after 
the leaves have fallen to the ground. The asci enclose eight sporidia. 

Birch Polypore, Polyparus betuUnus, is a hoof-shaped fungus often found 
on dead Birch-trees, and sometimes attacking and destroying living trees. It 
measures .*5-8 ins. across, and is soft and whitish when young, becoming firmer 
and brown with age. The mycelium is probably perennial, so there is no 
hope of saving a tree when once attacked. To prevent the dispersion of 
spores, all specimens of the fungus should be destroyed. 

Crack Willow Bust, Melamspora epitea, is found on the foliage of several 
species of Salix, in the form of minute orange powdery pustules. The 
globose uredospores are pale yellow, and the cylindrical teleutospores are 
at first brown, then nearly black. Both are present on the underside of 
the leaf. 

Conifer Boot Bot, Trametes radiciperda, is the most dangerous of all the 
parasites met with in coniferous woods. It attacks Scots Fir, Weymouth 
Pine, Norway Spruce Fir, Silver Fir, and other conifers, causing the worst 
form of red-rot. The mycelium forms a felted mass between the bark-scales 
of the roots, scarcely as thick as the finest tissue-paper, and the sporophores 
appear as small cushion-like structures, coalescing to form a thin white cake, 
usually 1-2 ins. in diameter, but sometimes measuring as much as 16 ins. 
across. The spores may possibly be disseminated by mice or other burrowing 
animals, but usually the disease spreads by means of the mycelium travelling 
from a diseased root to any sound root which may be in contact. Having 
gained an entrance between the bark-scales of the root, the mycelium finds 
its way into the wood and travels up the stem, causing decomposition of 
the tissues, and the ultimate death of the tree. All diseased trees should 
be removed, great care being exercised to take from the ground every portion 
of the old stump and diseased roots. 

Elm-leaf Phloeospore, Phleosporu Uhni, is one of the commonest parasites 

on Elm leaves, sometimes attacking nearly every leaf on a tree. The small 

brownish spots are dotted with pustules from which there exude whitish threads 

lxxii

of conidia, each divided into five cells. This is supposed to be the first stage 
of the Elm-leaf Blotch. 

Elm-leaf Scab (Piggotia astroidea) is thought to be the second stage. It 
occurs as small blackish scabs on the upper surface of the leaves. The scabs 
are composed of minute tubercles, from which conidia exude. 

Elm-leaf Blotch (PhyUachora Vlmi) is not unusual on Elm-trees, taking 
the appearance of rounded, convex, nearly black blotches on the upper surface 
of the leaves. The fungus matures after the fall of the leaves, the cavities 
containing numerous cylindrical sacs or asci, each enclosing eight sporidia. 

Hawthorn Powdery Mildew (Podosphcera Oxyacanthce) frequently whitens 
the leaves of Hawthorn, powdering them with the fallen conidia. The minute 
receptacles have 8 10 shortly branched appendages, about equal in length to the 
diameter of the receptacles. Each of the latter contains only one ascus, enclos- 
ing eight sporidia. 

Hawthorn Cluster-cups (RcesteUa lacerata) is a species of fungus found 
on the leaves, petioles, and fruits, taking the form of tufts seated on orange spots. 
The flask-shaped or cylindrical peridia are much lacerated and fringed at the 
margins, and ultimately split nearly to the base in reflexed thread-like filaments 
of attached cells marked with wavy lines. The yellowish aecidiospores are nearly 
spherical and warted. These cluster-cups are believed to be the first stage in 
the life of the Juniper Jelly-rust (Grymnosporangium clavariiforme), and are often 
now called by this Latin name. 

Hornbeam-leaf Blotch (Gnomoniella fimbriata) attacks the living foliage 
in the form of black convex blotches containing receptacles, each terminating in 
a spine-like neck, and enclosing oblong asci with eight sporidia. The conidial 
stage is believed to be the Glceosporium Carpini, a form of anthracnose in which 
the cylindrical conidia are expelled in whitish tendrils. 

Laburnum Leaf-spot (Phyllosticta ( 'ytisi) takes the form of brownish, circular 
spots, over which are scattered the dot-like receptacles containing curved 
sporules. 

Larch Canker (Dasyscypha calycina or Peziza Willkommii). The Larch 

disease is thought to be caused by this Peziza, which is found on the twigs and 

lxxiii h 



TREES AND SHRUBS 

branches, especially when the Larches are growing in low, damp situations. 
The fungus is a wound parasite, its spores entering by wounds caused by insects, 
hailstones, or the fracture of a branch through excessive weight of snow. It 
consists of tiny white cups of a waxy consistency, having an orange-yellow disk 
formed of closely packed asci, or spore eases, each containing eight sporidia. 
Mixed with the cylindrical asci are erect sterile filaments known as paraphyses. 
The hark is destroyed above the area occupied by the mycelium of the fungus, 
and when the diseased spots spread so far as to girdle the trunk or branches, the 
part beyond will die. In damp localities the mycelium appears to spread rapidly 
through the entire plant, and the cups, or ascosphores, may be developed over 
every part of the tree. 

As a preventative plantations of Larches should not be made in damp, 
lowland localities. To check the disease all canker spots should be removed on 
their first appearance, and the wound dressed immediately with a wash of cor- 
rosive sublimate in methylated spirit, or with a strong solution of sulphate of 
iron, and then painted over with tar. 

Maple-leaf Blotch (Rhytisma punctatu/m) occurs as yellow spots nearly 1 in. 
in diameter, and dotted with disconnected portions of a black scab or crust. 
The final stage is passed on the fallen leaves, and consists of clavate asci contain- 
ing eight needle-shaped sporidia. 

Maple Mildew ( Uncinula Aceris) sometimes covers the foliage of Hedge 
Maple so completely as to give it the appearance of having been drenched with 
a thin coating of whitewash. The appendages of the receptacles are hooked at 
the apex. The receptacles enclose eight asci, each containing eight sporidia. 
The pest may be kept in check by the application of sulphur and lime. 

Mountain Ash Cluster-cups [Rcestelia cornuta). The peridia occur in 

tufts on rusty orange-coloured spots on the under surface of the leaves. 

They are long, cylindrical, horn-like, curved tubes, serrated at the margin, 

but do not split into threads. They are whitish at first, and then become 

yellowish-brown or reddish, and contain brownish-yellow secidiospores. The 

teleutospore stage is said to be the Juniper Jelly-mass (Gym/iosporaHgium 

juniperinum), and the fungus is sometimes described under this name.

FUNGOID PESTS 

Pine Cluster-cups (Peridermium Pint). The cluster-cups, which appear in 
May or June, usually on the Scots Pine, and sometimes on the Weymouth 
Pine, are of two forms, those found on the leaves being cylindrical or 
laterally compressed, and having an irregularly torn margin ; others, found 
growing in crevices of the bark on the young twigs, are larger and inflated, 
and have the mouth spreading and much torn. The powdery a?cidiospores 
are orange coloured. The mycelium is perennial in the bark, bast, and wood. 
The cells attacked by the haustoria or minute suckers of the mycelium 
lose their contents, and afterwards secrete turpentine in considerable quantity, 
which escapes through cracks in the bark. When the disease encroaches on 
the wood, and checks the flow of sap, the branches die. The uredo and 
teleutospore stages are thought by some authorities to be the Senecio Rust, 
(Coleosporium Senecionis), and this name is sometimes applied to the cluster-cups. 

Black Poplar Rust (Melamspora populina) occurs on the leaves of the 
Black, Balsam, and Lombardy Poplars. The brown pustules of the uredo 
are roundish, and contain orange-yellow spores, mixed with capitate para- 
physes. The flat pustules of the teleutospores are generally crowded and 
often confluent, reddish-brown at first, and afterwards forming blackened 
crusts. The cylindrical pale brown teleutospores are closely packed side by 
side, becoming angular by compression. 

Sulphury AVood-rot (Polyporus mlfereus) is a large and showy poisonous 

fungus found as a parasite on the trunk of various trees, such as Oak, Alder, 

Willow, Poplar, Pear, Apple, and Larch. In the young state it is a round 

fleshy knob, but soon grows into an irregularly flattened body, crisped and 

waved on the margin, often with several overlapping portions or pilei, one 

above the other. A well-grown specimen may measure a foot in expanse, 

and weigh several pounds. The fungus is a bright sulphur-yellow, becoming 

paler on the smooth upper surface when old. It is brittle, with a soft 

whitish flesh and a disagreeable smell. Beside the usual reproduction by 

basidiospores, there are also conidia produced in abundance from the mycelium 

growing in cavities of the wood, or sometimes in the flesh of the polypore. 

The fungus is an annual, growing rapidly, and decaying in the autumn.

TREES AND SHRUBS 

The spores gain access through a wound, such as a broken branch or an 
unprotected surface exposed by pruning. The mycelium attacks the heart- 
wood, changing its colour to a clear reddish-brown, and causing it to crack 
and decay. 

Parts exposed by pruning, and the ends of broken branches, should be 
protected by the use of a fungicide. All specimens of the polypore should 
be removed and burned, and the surrounding wood cut away to the depth 
of an inch, the cut surface being washed with a saturated solution of cor- 
rosive sublimate in methylated spirit, and afterwards painted over with tar. 

The Spruce Nectria (Nectria cucurbitula) attacks the Norway Spruce, 
and sometimes the Silver Fir and Scots Pine. It is a wound parasite, gaining 
entrance by means of cracked branches, bruises caused by hail, and on the 
Continent through wounds made by the larvae of a Tortrix moth (GraphoMtha 
pactolina). The fungus chiefly affects the cortex, but when this is killed 
the wood may also dry up and wither, and in this way the top of a tree 
often becomes yellow, withers and dies. The mycelium is most active in 
the soft bast ; and when the dead bark is almost constantly damp, numerous 
small cushion-shaped or mushroom like bodies called stroma burst through 
to the surface. These at first bear numerous conidia, followed at a later 
period by red perithecia, which produce colourless sporidia contained in asci. 
To prevent the spread of the disease it is considered advisable to cut off 
and burn the tops of dead trees. 

Sycamore-leaf Blotch (Rhytisma acerinum) is common on the upper surface 
of the leaves of Sycamore, as well as at least three other species of Acer, 
viz. the Common, Norway, and Red Maples. On their first appearance in 
June or July the blotches are yellow, but soon change to pitch-black, the 
surface becoming wrinkled or corrugated and scab-like. Within the scab- 
like covering or stroma are cavities from which there ooze out minute curved 
spores or spermatia. During the winter an ascigerous form of fruit is pro- 
duced on the fallen leaves, the sporidia being needle-shaped and colourless. 
All diseased leaves should be collected and burned before the ascospores are 

liberated in the spring.

FUNGOID PESTS 

The Vegetable Beef-steak or Oak Tongue (Fistuhna hepatica) is found 
on living Oaks, not infrequently in the same position, year after year. It 
first appears as a reddish knob, rather like a strawberry, but soon enlarges, 
becoming darker in colour, sticking out horizontally from the tree, and 
much resembling the tongue of an animal in shape and appearance. As it 
ripens it becomes more succulent, being soft and easily cut, internally 
mottled somewhat after the manner of beetroot, and though it perhaps 
more closely resembles a piece of bullock's liver, it is not difficult to 
account for its common name of Vegetable Beef-steak. It usually 
weighs from three to four pounds, but specimens have been found weighing 
as much as thirty pounds. Though bitter and astringent when young, it 
is said to be quite nice if stewed with butter when thoroughly mature. 
The under surface is perforated with innumerable minute holes — the mouths 
of the closely packed tubes — which bear the salmon-coloured spores on their 
inner sides. Being always found on the dead parts, it is doubtful to what 
extent the fungus is a cause of injury to the tree. 

Willow-leaf Blotch (Rhytisma salicinum) is found on the Goat Willow 
and several other species of Salix. The blotches are large, circular, or 
irregular, rather shining and pitchy-black, the internal stroma being white. 
The ascigerous stage is found on the fallen leaves which have passed the 
winter on the ground. The clavate asci contain eight needle-shaped, curved 
sporidia. Diseased leaves should be collected and burned. 

Willow Mealy Mildew or Blight (Uncinula adunca) attacks the foliage of 
Willows, Poplars, and sometimes Birch. The mycelium is rather thin and 
white, and the falling conidia increase the mealy appearance of the leaves. 
The minute, dot-like receptacles are surrounded by a rather dense circle 
of unbranehed, hooked appendages. Each receptacle contains 8-12 asci 
furnished with four spores. 

Witches' Broom of Birch (Exoascus turgidus). This is a somewhat similar 

growth to the " Witch Knots " already described in the chapter on Galls, 

but in this case the abnormal growth is the result of a fungus belonging 

to the great group of Ascomycetes. In the genus Exoascus the asci, or spore 

lxxvii 



TREES AND SHRUBS 

sacs, are quite exposed, instead of being enclosed in a perithecium. The 
asci arc developed in spring and summer on the under surface of the leaves, 
which curl up, lose their fresh green colour, becoming sickly in appearance, 
and covered with a velvety, greyish-white hoariness. The contained sporidia 
are globose. 

Witches' Broom of Hornbeam is produced by Exoascus Carpi ni. 

Witches' Rroom of Pines {Peridermium {JEcidium) elatinum). This fungus 
is parasitic on the Stone Pine and various species of Silver Firs. The 
mycelium causes fusiform swellings or canker knobs, from which often arise 
the deformed shoots, bearing pale green swollen needles. It is perennial in 
the cortical and bast tissues of the stem, and even penetrates the cambium 
and wood ; in the latter case giving rise to canker-swellings, with or without 
the witches' broom. The leaves of the latter remain yellowish, and towards 
autumn they bear two rows of whitish recidia or " cluster-cups " on their 
underside. After the discharge of the Eecidiospores, the leaves die and fall 
off. Each year the mycelium advances into the new shoots, and the 
witches' broom increases in size, its growth continuing for perhaps twenty 
years. In young woods all trees that show cankerous swellings should be 
removed.

CHAPTER V 
FUNGICIDES AND INSECTICIDES 

The following Formula. 1 have been compiled from many sources, several 
of the most common being derived from the leaflets issued by the Board 
of Agriculture and Fisheries. By the kind permission of the editor several 
others have been taken from volume xxxiv. part iii. of the Journal of the 
Royal Horticultural Society ; these are marked with an asterisk (*). Many of 
the variations of Formula? are the results of years of patient experiment, 
and experts are agreed that we have yet much to learn in the matter of 
spraying for the eradication of pests. In the meantime there is great truth 
in the remarks of two of our well-known experts when they say, " The 
grower must know what to spray for, what to spray with, and when to do 
it." It is hoped that this chapter will give a few useful hints to those who 
may be on the look-out for simple remedies. Those more especially in- 
terested in the question of spraying of fruit-trees may be referred to the 
above-mentioned Journal, which contains a full account of the admirable 
papers read at the Conference held in October 1908. 

Ammoniacal Carbonate of Copper. Useful in epiphytic diseases, such as 
Rose Mildew. 

I. Dissolve 5 ozs. carbonate of copper in 14 pint water; slowly add 3

use on ripe or ripening fruit for four weeks previous to gathering. 

Bisulphide of Carlton. Useful in subterranean attacks of Woolly Aphis 
or Apple Root Louse. 

One fluid ounce of bisulphide is sufficient for a good-sized tree. Inject 
into soil in four places 2 ft. away from trunk of tree. 

Bordeaux Mixture. The cheapest and best all-round fungicide. 

I. Dissolve 6 lbs. sulphate of copper in 25 gallons water in a barrel; in 
another vessel dissolve 4 lbs. unslaked lime, adding water slowly, and making 
up to 25 gallons; when cold mix the solutions, and stir well during 
spraying. Never use air-slaked lime, as it injures the foliage. 

* II. Woburn Recipe. Copper sulphate, 10 ozs. ; lime-water, S\ gallons ; water 
to make 10 gallons. Dissolve the copper sulphate in ^ gallon of water ; 
run in 8} gallons clear lime-water; add water to make 10 gallons. To make 
lime-water gradually slake | lb. quicklime, add 12-15 gallons water, stir 
once or twice, and allow to settle. The mixture is not fit for use until 
addition of a few drops of potassium ferrocyanide produces no red colour; 
if necessary add lime-water until red colouration ceases on testing. 

Caustic Alkali Wash. I. Beneficial where fruit-trees are infested with 
moss and lichens, or with AVoolly Aphis. Use as spray in February. 

Dissolve 1 lb. commercial caustic soda in water ; dissolve 1 lb. crude 
potash (pearl-ash) in water; mix solutions, and add f lb. soft soap or agricul-

TREES AND SHRUBS 

Class I Dicotyledons 

Division I Thalamiflorce 

Natural Order . . . Ranunculacece 

Herbs or climbing shrubs, with an acrid juice ; Leaves radical or alternate, 
rarely opposite, generally sheathing at base ; Sepals usually 5, deciduous, 
often petaloid ; Petals usually 5, sometimes wanting, often deformed and 
serving as nectaries ; Stamens indefinite, hypogynous, anthers basifixed ; 
Carpels numerous, l-celled ; Fruit an etasrio of achenes or follicles, or rarely 
a berry. 

Distinguished from Rosacea; by the hypogynous stamens and deciduous 
calyx. 

The Crowfoot or Buttercup Family comprises many hundreds of species 
arranged in thirty genera, most of them being herbaceous plants, distributed 
throughout cool and temperate climates. The shrubby plants in cultivation 
consist of about thirty-five species of Clematis (mostly woody climbers), two 
Tree Pasonies, and the American Shrubby Yellow Root. Some members of 
the Order are extremely poisonous, and the juices of most are acrid. 

The name Ranunculus (L. rana, a frog) is said to have been applied 
by Pliny to the chief genus, from the fact that some of the aquatic species 
grow where frogs abound. 

TRAVELLER'S JOY, Clematis Vitalba. 

A native of Britain, especially favouring dry, chalky soils, climbing over 
our hedgerows, and in woods and thickets. Being a quick-growing climber, 
it is suitable for covering unsightly objects, and its small greenish-white 

A 



TREES AND SHRUBS 

flowers are followed by the 1 -seeded fruits, from which hang long whitish 
feathery, hair-like tufts, very attractive in winter, and making its popular 
name of Old Man's Beard most appropriate. June — August. 

The genus Clematis consists chiefly of deciduous shrubs, many of which 
are planted in the garden for the variety, size, and brilliancy of their 
gorgeous flowers, the rapidity of growth, and the ease with which they 
may be trained to trellises or walls, or made to climb up stumps of old 
trees or over rockeries. Their height may range from 1 to 30 ft. ; and their 
white, blue, purple, or yellow flowers are in evidence from April to October. 
They thrive best in a rich loamy soil with a fair share of leaf-mould and 
decayed manure, with an addition of road grit to keep the whole open 
and allow the free ramification of the roots. The genus has been greatly 
improved by hybridisation, and the number of varieties is ever increasing. 
Many do well on chalky soils. 

The species and varieties are mainly propagated by grafting small scions 
on pieces of roots of old plants in spring. Cuttings also are taken in 
spring, and shoots may be layered at all periods. Seeds are sown in light 
sandy soil in gentle heat in March, and the seedlings transplanted outdoors 
in June or July. 

Flowers 1 in. diam. ; honeyless, with sweet almond scent ; borne in a 
panicle at ends of short axillary or terminal branches ; pedicels shorter than 
leaves ; Sepals 4-5, petaloid, valvate, pubescent ; Petals ; Stamens indefinite, 
hypogynous; Carpels numerous, 1 -celled ; Fruit an etaerio of 1-seeded achenes, 
with the persistent styles transformed into long feathery awns. 

Leaves opposite, pinnate or ternate, leaflets 3-9, usually 3-5, ovate- 
cordate, entire, toothed or lobed, downy beneath, veins prominent, petioles 
persistent when twining. 

A deciduous shrub, climbing by its twisted petioles ; Stem woody, young 
stems 6-angled, dark olive-green, downy. 

Generic name derived from Gr. klema, a twig or tendril ; specific " Yitalba," 

in a contraction of vitis alba, meaning " white vine," both names referring 

to its trailing habit. Juice of leaves said to be employed by beggars to

Class I Dicotyledons 

Division I Thalamifloroe 

Natural Order . . . Magnoliacece 

Trees or shrubs, with alternate, simple leaves, often coriaceous ; leaf 
buds enclosed in convolute membranous stipules ; Sepals 3, usually petaloid, 
deciduous ; Petals 6 or more, 3 in a whorl, imbricate ; Stamens indefinite, 
hypogynous ; Carpels numerous, free, or cohering at base ; Fruit an etaerio 
of follicles or achenes ; seeds with an aril- like testa. 

The Order much resembles Ranunculacea?, but the members are always 
trees or shrubs. The name was given in honour of Pierre Magnol (1638- 
1715), Professor of Medicine and Prefect of Montpellier Botanic Gardens. 

CUCUMBER TREE, Magnolia acuminata. 

Gardens, shrubberies. Makes a handsome tree when planted singly in 
the park or pleasure ground. May — July. 

The Magnolias or Water-lily Trees comprise about a dozen distinct 

species of ornamental hardy deciduous trees or shrubs, besides which there 

are some half-dozen others of garden origin. They thrive best in a rich, 

deep sandy loam, of free and open texture, and when in a sheltered position 

or against a south or south-west wall. They are somewhat impatient of 

root disturbance. They are propagated by layering in summer or autumn, 

grafting in heat in July or August, and by seeds sown in sandy soil in 

spring or autumn. Seeds should be sown as soon as ripe.

Buds' small ; Wood aromatic. 

Native of California; discovered by Douglas, 1831. Syn. C. macrophyllus. 

WINTER FLOWER, Chimonanthus fragrans. 

Gardens, walls. November — February. The delicious fragrance of its 
blossoms makes this winter flowering shrub a general favourite. Near the 
metropolis it flowers well in the open, but is more often trained to a wall 
having a south or west aspect. It thrives in a deep, rich, sandy soil. The 
blossoms being produced on the previous season's wood, it is necessary to 
cut away, to within one inch of base, all shoots that have flowered, except 
the leading ones, which only need shortening. This pruning should be done 
in February, when flowering is finished. Propagation is effected by layering 
shoots in September or October. 

Flowers yellow or cream, purplish inside, in axils of leaves of preceding 
year, fragrant, 1 in. diam., appearing before leaves unfold, perfume re- 
sembling Jonquil ; Sepals, Petals, and Stamens numerous ; Fruit a capsule.

This Order contains some of our showiest of spring and summer flower- 
ing shrubs, over forty species being grown at Kew, where there are also 
fifty slightly different forms of the Common Barberry. The blossoms are 
of all shades of yellow, and the flowering period ranges from May to 
October. Most of them will thrive in ordinary garden soil, but the rarer 
kinds require a compost of two parts loam and one part of peat and sand. 
Suckers and layers are put down in October ; ripened cuttings in sandy 
soil in a cold frame in September ; seeds fresh from the pulp or berry in 
a sheltered border in October or November. 



CORAL BERRY, Berberidopsis cor a /Una. 

This handsome evergreen climbing shrub does well in sandy soil when 
planted against a south or west wall, and needs protecting with straw or 
mats in winter, being fairly hardy in the south of England, and half-hardy 
in the north. Layering is done in autumn ; cuttings inserted in sandy soil in 
spring ; seeds sown in spring in well-drained pots of sandy soil. 

The deep crimson or coral-red flowers, globular in shape, and hanging 

from long, slender stalks, form a contrast with the dark green foliage, and 

make this a very ornamental shrub. July.

AMERICAN LIME, Tilia americana. 

Parks, gardens. .July, August. 

The Limes are handsome, lofty-growing trees, inhabiting the temperate 
regions of the northern hemisphere. Their flowers are noted for their delicious 
perfume, and the honey is said to excel all other kinds in delicacy of flavour. 
Their timber has been noted since the days of the Romans for its " thousand 
uses," and is specially adapted for the purposes of the carver. The liber or 
inner bark readily separates into thin layers, and constitutes the well-known 
Russian bast or bass. 

The species prefer a sunny situation and a moist soil, and are not very suitable 
for dry soils or exposed places. Propagation is usually effected by the layering 
of shoots in the autumn. 

Flowers yellowish-white, in a cyme; bract 4-5 ins. long, 1-1^ in. broad, 

peduncle glabrous, 3} -4 ins. long, pedicels angled ; Sepals 5, ovate, 

acuminate, pubescent, | in. long; Petals 5, truncate, crenate ; Stamens

and made conspicuous in winter by the deep green of its young shoots. Pro- 
pagated by cuttings in sandy soil in March ; seeds in light soil in April. Used 
as a stock for grafting the weeping variety in March. 

Flowers creamy-white, papilionaceous, in a loose terminal panicle, bracts 
small ; much sought after by bees when fallen to ground ; Calyx oblique, 
teeth short ; Ovary shortly stipitate, stigma terminal, minute ; Fruit a pod, 
moniliform, indehiscent ; seeds rare in Britain.
