TO THE MEMORY OF Dr. ^VIM AS A SLIGHT TRIBUTE OF RESPECT AND ADMIRATION FOR HIS MANY VIRTUES, DISPLAYED THROUGHOUT A LONG AND USEFUL LIFE. PREFACE. If a life devoted to the study of trees and plants be a sufficient excuse for an unknown author to intrude his views and experiences upon the public, then the writer of this volume feels at liberty to present his first offering. His principal inducement for undertaking a work of this kind was. the want he had himself experienced at the com- mencement of his own studies. Having for years awaited the appearance of a publication suited to the climate of this country, he at last concluded to compile the results of his own observation and practice. There has not heretofore been an American work on Conifers, giving descriptions of all the different species and varieties that will endure the climate of the Middle States ; and without wishing to detract from the merits of the few excellent works that treat upon this subject to a limited extent, he believes that the present volume will fill up a blank in our works on horticulture, that has hereto- fore been much felt. In its compilation he has collected much valuable information from the most approved writers on the subject, and added his own experience and observa- tion in a plain and impartial manner, with a view to aid his countrymen in making a selection of the most suitable Conifers for their respective situations. The differences of European and American author- ities, with respect to nomenclature, are numerous and per- plexing, and where there were dissimilar opinions, the author has studied the characteristics of the doubtful plants, and placed them under what he considered their 5 VI PREFACE. proper titles, without regard to nationalities or prejudices. The author acknowledges his indebtedness to the excellent works of Gray, Chapman, Darlington, Endlicher, Richard, Loudon, Gordon, Lawson, Murray, Nuttall, Michaux, and others, from which a portion of the descriptions have been drawn. To the following friends, who have aided him in his 11 labor of love" he would return his sincere thanks, whilst gratefully remembering the many acts of kindness received from others, who are not particularized in this place. To Thomas Meehan, editor of the " Gardener's Monthly," for his constant aid from the commencement of the work, and especially for valuable information in regard to the newer species. To his esteemed correspondent, Dr. C. C. Parry, of Davenport, Iowa, for many interesting notes furnished on our Rocky Mountain Coniferae. To Professors S. S. Rathvon, and J. Stauffer, of Lan- caster, Pa., for valuable notes on insects injurious to this family of trees. To Prof. George Thurber, of New York City, for his careful supervision of the whole work, and by whose prac- tical knowledge its value has been greatly enhanced. To the late John Evans, of Radnor, Pa., for many excel- lent ideas, as well as for numerous specimens contributed, the result of a long life of study and travel. To the late Dr. Wm. Darlington and Joshua Hoopes, of West Chester, Pa., for unvarying kindness, unsolicited assistance, and the advice and instruction which enabled him to become acquainted with this important subject. Should this first attempt be rewarded by the encourage- ment of the reader, and a renewed interest awakened even in a few, the author will feel that the time devoted to its compilation has been well spent.

N T R O D U C T O K Y In writing a work upon a particular family of plants, the author is at loss to know how fhr he can presume up- on the knowledge of the reader with respect to plants in general. Believing that there are many who would con- sult this work to learn some points about Coniferce, or Cone-bearing plants, who are not familiar with plant structure and the systems of classification, the writer has preferred to be elementary and explain many terms that, to the botanical student, would need no definition. No one who has not attempted to write a work that shall be equally useful to the experienced man and the novice, is aware of the difficulties attending the task. We are obliged to assume that the reader is aware — or if not ad- O vised, we have to state — that all plants are divided into two great series, the Flowerless and the Flowering Plants. The former are called Cryptogamous, meaning plants with hidden fructification; and the latter Phcenogamous, or those in which the parts concerned in fructification are readily observable. Flowering (Phcenogamous) plants, those with which we are most familiar, are subdivided into two classes : Dicotyledonous plants, having two seed-leaves to the young plant, or embryo, and their stems showing a distinct pith, wood and bark ; and the Monocotyledonous plants, that have but one seed-leaf to the embryo and no distinct wood, pith, and bark in the stem. Besides this, 7 8 THE BOOK OP EVERGREENS. monocotyledonous plants have usually leaves with parallel veins, while those of the other class have the veins of the leaves more or less interwoven or netted. The stems of the woody dicotyledonous plants show a regular annual growth ; each year a layer of wood is deposited outside of the older growth, and they are called Exogens, or outside growers, while, as this order of growth is not observed in the monocotyledonous plants, and the newer woody fibres are mostly in the centre of the stem, they are called Endogens, or inside growers. To the first of these classes, the JExogens, or Dicotyledons, belongs the Coniferae, or Pine Family, which presents peculiarities of structure differing from other Exogens, and which will be described farther along. To the Cryptogamous or flowerless plants belong the Mosses, Ferns, Club-mosses, and Others still more simple in their structure. Geological researches have shown that after the forma- tion of this lower order of vegetation, the Coniferce came into being. This period was coeval with the formation of stone coal, which is indicated by the distinct and beauti- ful impressions found in the various strata throughout the coal regions. In the three great periods or epochs of geological his- tory, we find by the vegetable remains that, during the first period, their flora consisted principally of the crypto- gaim'ge, or flowerless plants, with a few dicotyledonous plants. These two classes were about equally divided in the second period ; and in the third, the dicotyledonous plants constituted much the larger portion, whilst the cryptogamia were rare. Monocotyledonous plants existed in every period, al- though by no means plentiful in any of them. In the first period the prevailing families were Ferns and enormous Equisetums, or Horse-tails ; in the second epoch, only one-third were Ferns, and the remaining two-thirds INTRODUCTION. 0 Coniferae and Lycopodiaceae, or Club-mosses, with inter- mediate allied forms. The third period presented much the same disposition of vegetation as the present existing forms. Dr. Buckland, in his Bridgewater Treatise on Ge- ology, says: "The family which has most universally pervaded every stage of vegetation is that of Coniferae, increasing in the number and variety of its genera and species at each successive change in the climate and con- dition of the surface of the earth. This family forms about one three-hundreth part of the total number of ex- isting vegetables." The ancient writers frequently mention the existence of the Coniferae, and used the Pines and Cedars as striking illustrations of strength and durability. The Romans used garlands of pine branches for crowning the victors in their games, and the wood to form their funeral piles. The cones and seeds were considered medicinal, and were sought after for flavoring their wines. The rare graceful- ness and artistic arrangement of many of the species were used as models by the sculptor, and the timber was employed for building purposes. According to Theophras- tus, an early Greek writer, the wood of the pine was so saturated with resin that it formed excellent torches, which were used at the sacred ceremonies. The assertion of Pliny that the wood of the Larch never creates a flame when burning, as well as that it never flowers, is an error that leads us of the present day to question whether he ever saw the tree. The same author speaks of the preservative properties of the juice of the Cedar, and states it was used in preparing mummies^ The Cedar of Lebanon was considered by the profane writers as symbolical of durability, but it is very probable that other Conifers were known under this name. The wood of the Cypress was also held in great respect by the ancients, and the branches employed in religious 1* 10 THE BOOK OF EVERGREENS. exercises. Its "balsamic properties were considered medic- inal, even to the odor exhaled from the trees. The tim- ber was used extensively in both naval and civil architect- ure ; and in ornamental plantations, particularly for ceme- tary purposes, the Cypress was regarded as the most eli- gible plant known. The Juniper was also known to the early writers, being noticed by Pliny and Virgil ; and whilst they generally admit the medicinal virtues of the fruit, its shade was considered by them as highly injurious to animal life. The Yews are, perhaps, more frequently mentioned by the an- cient writers than any other genus of the Coniferae, allu- pions being made to them in the writings of Caesar, Pliny, Suetonius, Nicander, Plutarch, Galin, etc. Their poison- ous properties appear to have been greatly overrated, for Gerard, the quaint old writer, in his day exposed the fal- lacy of most of these statements. The exceeding toughness of the wood of the Yew, how- ever, was known and appreciated, for it was used exten- sively for manufacturing bows. The custom of planting the Yew around the graves of the departed was universal with the ancients, and has continued popular until the present day. In many places throughout the sacred writings we find the Conifers beautifully mentioned, the similes often be- ing among the most eloquent passages known in the Eng- lish language. The Cedars are much more frequently quoted than any other genus, and are particularly described as being ex- ceedingly durable and strong ; thus endorsing the state- ment^ of the profane writers, but in which we, of the present day, cannot acquiesce. So highly was the Cedar tree held in the estimation of the inspired writers that the attributes of strength, height, size, growth, and fruitful ness were constantly made comparable to this tree. The Fir was seldom mentioned, and the Pine was alluded to INTRODUCTION. 11 even less frequently. In the First Book of Kings it is stated that Elijah "lay and slept under a Juniper tree in the wilderness." This tree is also incidentally mentioned in the Books of Job and Psalms, but we believe, with these exceptions, in no other instance throughout the Scriptures. The Yew is not alluded to by any of the sacred writers. According to Loudon, " the first author who wrote ex- clusively on trees and shrubs appears to have been Belon, a Doctor of Medicine of the faculty of Paris, who pro- duced a small quarto volume, entitled: De Arboribus, Coniferis, Hesiniferis, etc., printed in Paris in 1523, and illustrated with a number of engravings on wood. Dif- ferent species of Juniperus and Cupressus, the Thuja Orientalis, Cedrus Hbani^ and several pines and firs, as well as the Larch, are described and figured ; and a num- ber of other plants are mentioned incidentally." Since Belon's time, however, the French have paid the Coni- fers marked attention; more, perhaps, than any other nation. Loudon also says : " In Delamarre's Traite Pratique de la Culture des Pins, 3rd Edition, published in 1834, will be found an alphabetical catalogue of forty-three authors, who have written more or less on the culture of the Pine in France." Among the many writers on Conifers, the same author- ity states that Tournefort was the first to study them scien- tifically, and to class the order into genera, as described in his Institution es, published in 1717 and 1719. He was followed by Linnsus in his Genera Plantarum, published 1737; by Adanson, in his Families des Plantes, published 1763 ; and by Jussieu, in 1789, in his Genera Plantarum. These writers were succeeded by Solander, in 1786 ; by Gsrtner, in 1791 ; by Lambert, in his first volume entitled Monograph' of the Genus Pinus, published in 1803; which was followed by his second volume in 1832, and the third in 1837. Other botanical authors have, during the 12 THE BOOK OF EVERGREENS. present century, devoted much labor to the investigation and proper classification of this important order. Promi- nently, we may mention the names of L'Heritier, Smith, Link, Persoon, Barrelier, Salisbury, Ventenant, Desfon- taines, Tazzetti, Schubert, Richard, Mirbel, Tristan, La- marck, R. Brown, Michaux, Rafinesque, Don, Lindley, Loudon, Douglas, Menzies, Endlicher, Siebold, Hooker, Knight, Nuttall, and others, with the more recent authors, Carriere, Gordon, Veitch, Murray, Engelmann, Gray, Par- ry, etc. The great natural order Conifers very appropriately derives its name from its peculiar mode of fructification, which signifies, literally, a Cone-bearing tree ; and, as a considerable number of distinct characteristics mark its every stage of growth from the embryo to the mature tree or shrub, it should claim, in 110 small degree, our pa- tient investigation and research. Having commenced, therefore, with the first evidences of its formation, we will follow its history through the changes that mark its growth. The ConiferaB is the only well-known order belonging to the sub-class Gymnospermcea / i. e. naked-seeded. Their peculiar, yet simple, mode of fructification is exceedingly interesting to the botanist, and furnishes the most reliable and distinctive characters by which the different genera and species are distinguished. The several members of this important family are all trees and shrubs, abounding throughout their entire structure with resinous juice. Ex- amined by the microscope, the walls of their wood-cells are marked by curious circular disks and glands, but the wood is entirely destitute of ducts. The leaves are linear or lanceolate, diverging into needle-shaped, awl-shaped, or scale-shaped, with all their intermediate and combined forms ; excepting in the Salisburia, which ha*s a very cu- rious fan-shaped or wedge-shaped leaf, on a long petiole. The LariX) (Pseudolarix?), Taxodium, Qlyptostrobus, INTRODUCTION. 13 and Saltsburia r,produce deciduous leaves,and the remainder of the family are all evergreen, or have persistent foliage. The chief peculiarity of this order is in the naked ovules or rudiments of seeds, which are borne mostly on the inner surface of a scale or carpellary leaf, and fructified by the im- mediate application of the pollen, without the service of a pistil or the appendages of calyx and corolla. The flow- ers are borne principally in aments or clusters, and are either in the axils of the leaves, as in the Junipers and Yews, or at the extremities of the branches, as in the Pines and Cypresses. In the pistillate aments each indi- vidual carpellary scale acts as a separate and distinct flow- er, and the whole combination, when mature, forms a spe- cies of multiple fruit, or, as it is generally designated, a cone. The sterile flowers are also in aments, and usually consist of a small collection of stamens, adhering to the under side of a scale. In fruiting, this order displays a great diversity of forms and characters. In the sub-order AbietinaB and most of the CupressinaB the species are recognized by the woody cones of different sizes and shapes, whilst in the Juniperus and Taxacese the fruits in their primitive condition are small cones and furnished with carpellary leaves, but swelling at maturity into drupe-like berries, or fleshy, naked drupes. The albumen of the seeds is of an oily, fleshy consistency, with the embryo in. the axis. The cotyledons in this family range from two to many in a whorl. The near affinity displayed between many genera, as in Larix and Cedrus, Abies and Picea, Cupressus and Chamcecyparis (.?), Taxodium and Qlyptostrobus, etc., has caused much controversy and apparent diversity of sentiment in many of the authorities before quoted ; and even to this day no established rule can possibly be given to settle these disputed points. In the sub-orders, any one, by careful study, can ascertain the leading characteristics that bind together the different genera composing them, 14 THE BOOK OF EVEKGREENS. and thus be enabled to trace any particular tree or plant to a description in this work. The order is subdivided into three sub-orders, or sub- families, which are, by some botanists, given the rank of orders. The sub-order Abietince, or Pine sub-family, are all large sized trees, growing mostly in a conical form, and having large, spreading, roots, and horizontal branches with droop- ing branchlets. The members of this group all have ev- ergreen or persistent leaves, excepting the Larch, (Larix^) with both sterile and fertile catkins, usually on the same tree but on different branches. The cones, or strobiles, which form the main point in distinguishing the sub-or- ders, are in this very much alike in structure, although differing greatly in size and shape. Seeds, mostly edible, resinous and oily, the embryo with from 2 to 12 cotyle- dons. Buds, scaly. The sub-order, Cupressince, has, with few exceptions, smaller sized trees or shrubs. They are all evergreen ex- cept the Taxodiums and Glyptostrobus, with generally a conical form, which, in many instances, approaches the fas- tigiate. The cones of this group are smaller than those in the foregoing, and are composed of dry scales, excepting in the Junipers, which are drupe-like berries at maturity. Buds, naked. The Third sub-order, Taxinece, or Yew sub-family, is very distinct from the others, and is by many botanists separated from the Conifers. The species belonging to this are about equally divided between the medium-sized and smaller class of trees, and produce in fruit a naked drupe, or, in some instances, a fleshy, drupe-like berry. Buds, scaly. No known order of plants presents such a diversity of size as that of the Conifers. From the humble, trailing shrub, it embraces trees of every size to the lordly Sequoia gigantea of 300 feet in height. Every shade and tint of INTRODUCTION. 15 green is also beautifully displayed in the foliage of the various species, and in the many curious and unique vari- eties we have the variegated leaves that occasionally occur throughout the whole of our flora. The extensive fir and pine forests of Northern Europe that clothe the mountain ranges so universal in those coun- tries, cover millions of acres, and contain some magnif- icent specimens in size and beauty. But large as these enormous tracts appear, they are inferior to those of our Western regions. Immense tracts of timber clothe the summits and sides of a large portion of the Rocky Moun- tains, and the section of country west to the Pacific Coast. Some of the enormous trees found in these localities are of almost incredible size. Specimens of the Pinus Lam- bertiana, Picea nobilis, Picea grandis, and Sequoia gi- gantea, are often met with reaching a height of 200 feet and upwards. The several genera composing this order are limited to no particular climate or country, but are natives of the torrid, frigid, and temperate zones, throughout the whole world. Each region has its own representative, marked by its peculiar type of growth. On the coldest summits of the Alpine peaks of Lapland, at the very utmost limits of arborescent vegetation, are found many of the d warier species ; whilst, on the other extreme, the splendid Arauca- carias and Dacridiums develop their beauty beneath the scorching sun of a torrid clime. Although the family is not remarkable for producing edible fruit, and only a few members of it that of sufficient value for exportation, yet many of the species bear very nutritious seed, upon which the natives of those countries where they grow, almost entirely subsist. The Pinus Xambertiana, for instance, has large, dark- brown seeds, that are eagerly gathered by the Indians, and form one of their principal articles of food. The P. pinea also produces large, nut-like seeds, about three-quar- 16 THE BOOK OF EVERGREENS. ters of an inch in length, which are considered quite nutri- tious, and are even in limited demand as an article of commerce. For their medicinal and mechanical properties, the pro- ducts of this family constitute a very important item of traf- fic. Various so-called balsams and resins, that are service- able in the materia-medica, as well as the pitch, tar, rosin, and turpentine of trade, have yielded an immense annual income to the manufacturers. For building purposes, both in naval and civil architecture, the lumber furnished by the Abietina? is, perhaps, the most useful and valuable in the market. The immense rafts of White and Yellow Pine, as well as Hemlock Spruce, that are conveyed yearly to our large cities, contribute largely to their mercantile prosperity, and produce a livelihood for large numbers of workmen in those sections from whence it is obtained. CHAPTER II. SOIL AND PLANTING. We desire in this chapter to point out many of the evil practices into which planters, in this country, too fre- quently fall ; as well as to give a few concise instructions in regard to the proper time and manner of transplant- ing, selection and preparation of soils, etc. These rules are the fundamental principles upon which everything else depends; for, if correct ideas are wanting at the commencement, failure will inevitably be the result. In planting evergreens on a lawn, care must be observed to ascertain whether the soil is suitable for their healthy growth and subsequent development. With a very few exceptions, the Conifers prefer a light, sandy subsoil, open and porous, that will admit of a perfect drainage, yet with a deep, rich surface soil, to afford a proper supply of healthy nourishment to sustain the large quantity of fibres with which their roots are furnished. We have closely observed for a number of years that on stiff, clayey soils, or those which are retentive of moist- ure, the half-hardy species will inevitably be killed, or what is more annoying, be severely injured. Experiments in various parts of the country, in regard to this particular, have always decided that much more depends upon the quality of the soil, than on the temperature of the atmos- phere. The reason of this is obvious ; for, in almost every instance where an unacclimated tree has been injured, we 17 18 THE BOOK OF EVERGREENS. find that the plant has either been prevented from forming its growth early in the season, and, in consequence, has been overtaken by the frosts, or, as is very often the case, it has grown over-luxuriantly, and the nature of the soil has prevented it from properly ripening the young wood. An excellent example of the value attached to light soils is shown by a Deodar Cedar that is standing on our own grounds. This beautiful species has been pronounced tender by almost all planters, and its dissemination consequently discouraged. The specimen to which we allude is, at the present time, about 25 or 30 feet in height, and quite broad in proportion ; and so perfectly is it adapted to the situ- ation, and, to all present appearances, entirely acclimated, that it passes through each winter without the least pro- tection; and by all owners of heavy soils is regarded with undisguised astonishment. It is growing in a somewhat warm exposure, and in al- most pure sand, with a good, mellow surface. Thus, whilst the tree is debarred from making a rank growth, the wood ripens sound and healthy, and the very end buds remain until spring sound and full of vitality.* The magnificent specimen of Abies Douglasii, referred to in the description of that species, and at the present time growing in the Evans Arboretum, is another excellent example of the influence of soil on the growth of half- hardy plants. Trees that are natives of low, swampy grounds will also, in many cases, thrive satisfactorily in dry situations. Near the Deodar above mentioned, is growing a fine, healthy, deciduous Cypress, (Taxodium distiehum,) that inhabits the low miasmatic swamps of the Southern States; and yet, on this apparently dry ground, it flourishes with all the vigor that the wild trees do in their marshy soil. * This tree has, since the above was written, been killed by unprecedented^ severe weather. SOIL AND PLANTING. 19 We do no*t wish to be understood as recommending a poor, thin soil, but we prefer a good mellow surface that is not too rich, especially in organic manures, and that would produce fair crops of grain ; on such the great ma- jority of evergreens will develop that peculiar rich green foliage which causes the family to be so universally ad- mired. In all cases where the soil is not naturally in the above condition, the drain-tile should invariably be used, as stag- nant water, when allowed to remain in the vicinity of roots, is sure to cause decomposition. In such cases, when a tree is lifted, long, bare roots that are almost entirely destitute of fibres, are found in the place of a mass of small rootlets, ramifying in every direction. Another important consideration, and one that we pre- sume our cultivators have entirely overlooked, is the fact that different formations of soil tend to produce contrary effects in many species of the Coniferae ; and the same spe- cies that flourishes in a limestone soil, will not unfre- quently languish on a talc-slate, or red shale. As regards this indiscriminate planting without a proper observance of the especial constitutional requirements of each tree, we desire to call the attention of our readers to the fol- lowing remarks of the Earl of Ducie, which originally ap- peared in the Transactions of the Scottish Arboricul- tural Society, a few years since : " As a general and sufficiently obvious rule, the Coniferaa thrive in proportion to the depth of the surface soil on which they stand. This is especially the case with the Deodar and Finns insignis. The rule does not, however, appear to apply invariably to Abies Douglasii, as I pos- sess specimens growing as vigorously on the cold and sterile shales of the carboniferous limestone, as others on the deep and warm soil of the old red sandstone. " The most fastidious of the Coniferse which I have had an opportunity of observing, is, undoubtedly, Cryptome- 20 THE BOOK OF EVERGREENS. ria Japonica. On the limestone, its leading shoot is al- ways defective, and its growth generally devoted to the formation of a nest-like mass of small roots ; whilst, on the old red, a formation deficient in lime, its growth is regular, upright, and graceful, and so rapid that I have no hesitation in affirming that, in this locality, it would out- grow the Larch. " The Deodar, on the other hand, appears to be the least discriminating and the most accommodating of all the Coniferse. No position, and no variety of soil, appear to come amiss to it ; on lime or sandstone, rock or clay, it grows with equal facility, though depth of soil, as before stated, invariably contributes to rapid growth. " In Araucaria imbricata, though planted in consider- able abundance, and in every variety of soil, I have not been able to detect any decided preference for one forma- tion over another. It has an evident dislike to a wet lo- cality, and it generally, though not exclusively, thrives best upon a dry soil." A number of other instances are given, but as they are of species which we are debarred from cultivating on ac- count of climate, we have not quoted them. We are un- aware of any observations having been made in our coun- try in regard to this important subject, but as every incident connected with the proper acclimating of trees is of incalculable benefit to planters, we earnestly desire a careful investigation of this subject, believing it will even- tually lead to discoveries which will very materially en- large our list of available Conifers. In planting, a sufficiently large hole should be excavated to allow full scope for the roots to start vigorously into action. A very deep hole is unnecessary, as those roots that principally maintain the health and vigor of the tree extend near the surface of the ground ; and the large roots that penetrate downward for a great distance are for the purpose of sustaining the tree erect, and prevent- SOIL AND PLANTING. 21 ing the action of storms from disturbing its equilibrium. This latter class of roots is seldom of large size in nur- sery-grown trees, owing to their having been frequently removed ; but in a young seedling taken from the forest, it is almost always the only kind that are found. These tap-roots are considered by most writers on the sub- ject to be of only secondary importance in affording nourishment to the tree, the rootlets and small fibres thrown out just under the surface of the ground perform- ing that service. When transplanted, young forest trees very frequently die from the want of a sufficient number of these surface or fibrous roots ; but, were it not for the long and power- ful tap-roots when the tree arrived at maturity, and, as is .often the case, presenting a tall, branchless body, the tree would inevitably be destroyed by heavy winds. Every intelligent writer for years has "kept it before the public " that a tree should never be planted deep, and in fact, shallow planting is absolutely necessary to insure a healthy growth. In setting out a tree, allowance should always be made for the settling of the recently moved earth, so that when the soil returns to its usual compact- ness, the tree shall stand the same height as it did pre- viously to being disturbed. This is, perhaps, the most important part of the whole operation, and upon a close observance of this fact de- pends the future prosperity of the tree. In planting evergreens, many ignorant persons use fresh stable manure, placing it directly in contact with the roots. This will assuredly cause decomposition to take place, and the death of the tree will frequently be the result. The soil for filling-in should be taken from an old pas- ture, or along roadsides, first paring off the sod. This, with the addition of a little sand, unless the soil is naturally very light, is, without doubt, the most suit- able that can be used. When convenient, peat, from 22 THE BOOK OF EVERGREENS. an old swamp, that has been exposed in a heap to the frosts of at least one winter, and well decomposed leaf- mould, in limited quantities, will also prove beneficial. When fertilizing materials are used, they should be ap- plied to the surface, that the rains may carry the necessary ingredients contained therein to the proximity of the roots, which then gradually absorb the nourishment by degrees, and are not entirely suffocated, as -is often the case when an impatient planter indulges his passion for fertilizing, at the expense of his favorite tree. After planting, it is highly necessary that the tree should be securely fastened to stakes, for the purpose of prevent- ing the action of strong winds from displacing it; and, at the same time, it should be borne in mind, that the bark must be protected by straw bands or matting, to prevent rubbing. After carefully experimenting and watching with inter- est for many years the proper season for transplanting ev- ergreens, the author is compelled to add that so great a diversity of sentiment is apparent among intelligent plant- ers, that to advance any proposition as infallible would be entirely absurd ; and yet no question is so frequently asked a nurseryman as this. We know that many of our best cultivators frequently advance theories that are exactly contrary to those that we advocate, but as we are desirous of adhering strictly to well-known facts, and recording the results of our own experience in support of them, we request an impartial trial of our doctrines before they are condemned. The generality of the order, among which are the Pines and Firs, form and perfect their growth by midsummer. At that period, during a long and rainy season, they may be removed with excellent success ; but, should a drought set in, woe betide the poor tree, for all the waterings and mulchings that the anxious owner can bestow upon his favorite, will not avail ; — the plant will almost certainly SOIL AND PLANTING. 23 die. But we are quite willing to acknowledge that many hundreds of these trees are annually removed during this season, with entire success, and notwithstanding this, we repeat, local conditions are needed to insure success. While a tree belonging to another order is removed early in the spring successfully, the structure of the Conifene family is such, that an evergreen, transplanted at the same time, would doubtless fail. When the case is reversed and each is planted after the soil has become warmed by the sun's rays late in the season, and the trees show indications of growing, the latter will prove most decidedly more certain. This is a practical view of the case, and may be relied on. In a comparison of spring and autumn planting, the former season has long since been decided to be the most certain for removing ever- greens in this climate. The following extract from Lindley's Theory of Horti- culture gives an English author's views, although we differ from him in the above mentioned particular. " As evergreens are never deprived of their leaves, so they are never incapable of forming roots ; on the contrary, they produce them all winter long, and rapidly at any other pe- riod of the year which is favorable to their growth ; so that they are capable of making good an injury to their roots much more speedily than deciduous plants, especially as, in the majority of cases, the roots are numerous and fibrous, and not so liable to extensive mutilation when transplanted. Now, if an evergreen is planted in the month of May, and the weather happens to be cloudy, mild, and damp, as the plant is just then commencing the renewal of its growth, and is forming fresh roots abund- antly, if such a state of weather lasts for a week or two, there is no doubt the plant will succeed very well, and so it will if removed at midsummer." Again, the same author, remarks: "In short, I am certain that, if expe- rience only is looked to, it will give the same, answer as 24 THE BOOK OF EVEEGEEENS. theory to the question of what season is the best for plant- ing evergreens, namely : that which is best for other trees ; and such coses to the contrary as may appear to exist, will always be found exceptions to the rule, in consequence of some peculiar circumstances attending them ; not unfre- quently, I believe, from the operation having been per- formed upon a very small number of plants, to the removal of which a degree of care was given wholly incompatible with general and extensive practice." The editor of the American edition of'Lindley's work, the late A. J. Downing, thus comments upon the foregoing : " These remarks must be received with great modification, especially in the Northern and Eastern States. The moist or rainy winters of England are the exact opposite of our cold and dry ones, during which, for two months at least, the soil is severely frozen, and vegetation is nearly or quite dormant. Our whole experience goes to prove that the practice of transplanting evergreens in autumn is, for this country, extremely injudicious, as the damage which the trees sustain in their removal greatly increases their sfcs- ceptibility to injury by the cold of winter. The early spring is the most favorable period for the purpose, since the abundant and long continued rains which occur from the vernal equinox to the middle of April, enable the plant to recover itself and emit new roots with rapidity. We have been very successful in May, but then so much depends upon the occurrence of rainy weather that the risk is greatly increased. Next to the selection of the proper time, the preservation of the roots in a moist con- dition is the most essential point in removing all ever- green trees." As far as these remarks apply to the superiority of spring over autumn planting, they have our decided ap- proval ; but we cannot coincide with the writer's views in advocating an early spring removal. Practice has fully proven to us the utility of performing the operation about SOIL AND PLANTING. 25 the time the buds commence perceptibly to swell ; at that period the trees, when transplanted, start immediately into action and perform their functions in the new soil ; 011 the other hand, the peculiar fleshy texture of the roots renders them remarkably impatient of being in a state of inactivi- ty at such a period, and they will frequently perish from this cause, as is instanced in very early spring planting. The tenacity of life in the ConifersB is certainly less than in most deciduous trees ; therefore great care should be taken to always preserve the roots fresh and moist, when out of the ground. They evince at this critical season a strong desire for moisture, not only at their roots, but over their whole foliage. Trees, when removed during rainy weather, always succeed better than during a dry season. Another evil practice is the careless manner in which trees are too frequently taken up, sufficient care not being exercised to preserve the root fibres, as many ignorant gardeners deem the larger roots sufficient to maintain the life of the tree. In regard to this practice, Lindley says : "It would be the duty of the gardener to save every mi- nute fibre of the roots, if it were practicable ; but as this is not the case, his care must be confined to lifting his trees with the least possible destruction of those important organs ; remembering always that it is not by the coarse, old, woody roots that the absorption of food is carried on, but by the younger parts." Now, when these small root- lets are cut off by the spade during the digging process, every one so destroyed removes one of the vital organs of the tree, and lessens its chances of living. After removing a tree that has been growing in a situ- ation for one year, the ends of all such cut roots will be found supplied with a new set of fibres ; plainly showing that nature has endeavored to return to her fixed laws, relative to the growth of plants. An error into which many unpractised planters frequeut- 26 THE BOOK OF EVERGREENS. ly fall, is that of planting large trees ; and it is one which we consider so opposed to sound common sense, that it should meet with cHsapproval from every true friend of arboriculture. We are well aware that the owner of every new place is anxious to produce what is usually known as an immediate effect, and therefore he at once proceeds to plant large evergreens, covering his grounds with great, unsightly trees, swaying about with the wind, and in most cases destitute of branchlets or leaves on the lower limbs. Such a system as this may produce an im- mediate eifect, but it is certainly opposed to good taste. Men of experience seldom desire such trees, knowing full well the baneful effects of transplanting large ever- greens. In almost every case of this kind, the lower limbs are apt to die, and thus greatly disfigure the symmetry of the tree. The Pine family proper, in such cases, invariably shed their foliage on all the lower branches, and forever after present a pitiable sight. Young and healthy plants, when carefully taken up and as properly replanted, are never subject to this disfigure- ment, and are almost certain to form handsome specimens. Before leaving this subject, we desire to give a few di- rections for transplanting young seedling evergreens from the woods. Much disappointment very frequently results from the performance of this operation, notwithstanding it should be entirely successful if the proper conditions are observed. Such seedlings, it is well known, are gener- ally found in moist, shady localities, and, as is very reason- able to suppose, are utterly unable to withstand the heat of the sun after removal, or comparative dryness in the soil. After digging (not pulling) the plants, especial care is necessary that the roots be properly protected and not al- lowed to become in the least dry, as this is the most es- sential point in the whole transaction. They should then be carefully packed in damp moss, with numerous holes in SOIL AND PLANTING. 27 the box, to allow free circulation of air and prevent de- composition. The soil in planting must be light and deep, well pulver- ized, and in a shady situation, such as the north side of a building. The plants should be set in beds very thickly, after dip- ping the roots in a puddle of thin mud. As a covering we prefer evergreen boughs, raised about three feet above the plants on a rough trellis work. In this manner we have succeeded admirably with all kinds of young ever- greens, and especially with Hemlock Spruce and American Yew, which are generally considered to be the most im- patient of removal, CHAPTER III. PROPAGATION. The propagation of the Coniferse is, perhaps, the most difficult, and the least understood, of that of any order of plants grown by our nurserymen. The vicissitudes of a changeable and severe climate, with its conse- quent cold and wet winters, followed by hot and dry sum- mers, render the operation extremely precarious and uncertain, even under the hands of the most experienced propagator. Foreign gardeners upon their arrival in this country, feel confident the difficulties have been overrated, and therefore proceed in the course practised in the old country; a very short experience, however, convinces them of their mistake, and compels a resort to artificial means to accomplish what they have been accustomed at home to leave to nature. Conifers are increased by the seed, by cuttings, layers, and grafts. SEEDLIXGS. — " A seed," says Lindley, " is a living body separated from its parent, and capable of growing into a, new individual of the same species. It is a reproductive fragment, or vital point, containing within itself all the elements of life, which, however, can only be called into action by special circumstances." It is important to know what external causes affect the vitality of seeds, and in- duce or retard their germination. A seed contains a delicate little embryo, which consists of cotyledons or seed-leaves, and a radicle or primary stem, 28 PROPAGATION. 29 in a quiescent state, always ready to start into action if sub- jected to certain conditions that are absolutely necessary to awaken it into active life. The structure of seeds, par- ticularly in the thickness of their integuments, varies so widely in the different species, that it is necessary to study closely the characteristics of each, and follow a distinct course with the different kinds. For instance, many acorns germinate so readily, that the merest contact with moist- ure is sufficient to start vegetation ; but, on the other hand, the seeds of Holly and others with hard shells, will often lie dormant in the ground for three and four years. The embryo in many of the Coni- fers differs from that of most other exogenous plants in having more than two cotyledons, or seed-leaves. While the seedlings of some present only two seed-leaves, in others there will be a whorl of several — sometimes as many as fifteen. Fig. 1 shows a young seedling of Norway Spruce just germinating. A perfectly ripened seed will retain its vitality just so long as the various substances composing it, such as starch, oils, etc., can be preserved from decomposition. For this reason the seeds of Conifers are generally difficult Fig. 1.— GERMINATING to preserve unimpaired for a long time, owing to the excess of oil they contain. Seeds pro- duced by this order should, invariably, if possible* be allowed to remain in the cones until wanted for planting, as no artificial package can supply the place of these natural receptacles. Darkness, although not in all cases a necessary condi- tion in the germination of seeds, is, however, important ; as in the absence of light the chemical changes take place 30 THE BOOK OF EVERGREENS. more freely, and, consequently, the embryo is brought into action more readily. The practice of old gardeners of placing their seeds on cotton in a vessel of water, for the purpose of testing their vitality, is well known ; and we have seen acorns, while on the parent tree, sprouting. But these are only illustrations showing how readily some seeds germinate, and should be regarded as exceptions to the general rule. If seeds of the Conifers are to be sent long distances, they must be protected from contact with moisture, •whether in the air, or in the packing material. An excel- lent method for protecting seeds from the atmosphere is to place them in a tightly corked bottle ; but this plan has its disadvantages and is deprecated by many, but for lim- ited periods we have seen excellent success result from it. Various plans and suggestions have been offered by men of experience for transporting seeds, yet none are entirely infallible. Probably the best method is that recommended by Prof. Lindley. He says: "Upon the whole, the only mode which is calculated to meet all the circumstances to which seeds are exposed during a voyage, is, to dry them as thoroughly as possible, enclose them in coarse paper, and to pack the papers themselves very loosely in coarse canvass bags, not enclosed in boxes, but freely exposed to the air ; and to insure their transmission in some dry, well ventilated place. "Thus, if the seeds are originally dried incompletely, they will become further dried on their passage ; if the seed-paper is damp, as it almost always is, the moisture will fly off through the sides of the bags, and will not stagnate around the seeds." The same authority states : " For seeds containing oily matter, which are peculiarly liable to destruction (by their oil becoming rancid), ram- ming in dry earth has been found advantageous." Our own experience with this latter plan has been very satis- PROPAGATION. 31 factory ; and we have likewise found pure, dry sand use- ful for the same purpose. Warmth and moisture are the principal agents that induce germination, but a superabundance of either just as readily causes decay. The moment seeds are placed in contact with moisture, they absorb oxygen, the starch and other compounds are decomposed, carbon- ic acid is given off, and the development of the em- bryo plant commences. It is also necessary that a certain degree of heat should attend the operation, and the amount varies in different species of plants ; there- fore no definite rule can be given, but the judgment of the propagator must be exercised to prevent an excess, and, what is equally requisite, preserve a sufficient amount of warmth in the soil. Most seeds of the Coniferge germinate easily, but the young plants are so sensitive to adverse circumstances, such as dampness, heat, drought, etc., that they are ex- ceedingly liable to be lost before forming their true leaves. This is the critical point in raising seedlings ; for, after the plumule has developed into leaves, and the radicle has formed sufficient fibres to nourish the young plantlet, the danger is chiefly past and less care is required in its growth. Seeds should always be sown thinly and evenly for sev- eral reasons. If the young plants stand too close to each other, a portion are shaded, which not only draws them up with long stems, but in many cases destroys them en- tirely. The stronger also abstract the nutriment from the soil, to the detriment of the weaker plants, and the latter very soon become stunted and often worthless. A high temperature is decidedly unfavorable to the growth of seedling Conifers, and, for this reason, the seed, when planted in the open ground, should either be sown in the autumn, or, as some of our best propagators now prefer, as early in the spring as the frost will allow. 32 THE BOOK OF EVERGKEEXS. These observations of course do not apply to natives of tropical climates, for the temperature in growing these must be so graduated as to suit the nature of the plant. As an excess of moisture is one of the greatest evils to be guarded against, especial care must invariably be taken that the soil during the critical season is only sufficiently damp to preserve the young seedling from wilting, whilst the humidity in the atmosphere (when the beds are covered with sash) may be maintained by syringing slightly, or watering through a fine rose. In fact, water should never be applied in large quantities, as if the young plants were radishes or cucumbers, but as gently as possible, to imitate an invigorating dew. Dry ness, on the other extreme, is almost sure to pro- duce decay; for when young evergreens once suffer for want of moisture in the soil, they rarely recover, and oc- casionally the sudden transition from drought to damp- ness kills them almost immediately. Although a large proportion of the seeds produced by the Conifers will germinate readily, the Yews appear to be an exception. The hard, bony integuments of their seeds closely resemble those of the Thorns, and conse- quently require to be sown immediately after gathering. Our plan is to wash the pulp from the seed, and sow at once in light, sandy soil, cither in boxes or frames. The English method is to throw the fruit into heaps, when the soft, pulpy disks soon rot, and the seed is then treated as above. Should the seeds become dry before sowing, they will frequently lie in the ground for two and even three years before germination takes place. Seeds of the Cypress germinate and grow in a few weeks after sowing, but the Thujas, if not sown immediately after ripening, will lie in the ground for a year. Junipers, if not washed from their pulpy covering, will keep for several years ; but they are very slow about sprouting, and will usually lie in the ground for two years. PROPAGATION. 3l> A peculiarity of the cones of the Cedar of Lebanon is the length of time necessary to perfect them. They are generally not matured until the third year, and the seeds will keep well for five or six years afterward, provided they are left undisturbed in the cones. The seeds of some species as, for instance, those of the Cedar of Lebanon and several species of Pines, are ex- tremely difficult to dislodge from the cones. When this is the case, the cones should be thrown into hot water for a short time, which will loosen the scales, or a \vedge may be driven through the centre and the seeds obtained from the fragments. In the use of hot water, great care should be exercised that the seeds receive no injury. Cones are also frequently dried in the sun, or placed in a moderately warm kiln in order to procure the seeds. Seeds are often sown too deep, and perhaps as much dis- appointment arises from this cause as any other. Most seeds of the Conifer® require but a light covering, say from one-quarter to one-half an inch in depth. An excellent compost for growing seedling Conifers is sods, muck, and coarse sand, with a small portion of old, well-rotted manure ; the whole thoroughly incorporated, and allowed to remain in a heap at least one year before using. An occasional stirring of the mass is advisable. This should never be run through a sieve, but used in a rough state, simply pulverizing the larger lumps. The idea is to have well-rotted, fibrous earth, rich in vegetable, fertilizing material, coarse and light, with a perfect drain- age when in use. For growing the common varieties of evergreens, all that is needed is a simple cold frame with sash. The soil should be dug in the autumn, and prepared very nicely by working sand and well-rotted manure through it ; but nev- er, under any circumstances, fresh manure from the stables. The surface should then be raked evenly and smoothly, and the seeds thinly sown. We prefer pressing them into 2* 34 THE BOOK OF EVERGREENS. the fresh soil with the back of the spade, and covering with a thin layer of earth, then moistening with water from, a fine rose. Care must be taken through the winter to prevent the attacks of mice, which are exceedingly partial to oily seeds. An occasional airing on mild days will be beneficial ; and should the soil become dry, a slight sprinkling will be necessary. As the warm days of spring approach, the young seedlings will commence showing themselves above ground, and the attention of the garden- er is demanded at this particular period. A slight lifting of the sashes during the warmer portions of the day, care- ful syringing, and an occasional watering, will be neces- sary. As the plants mature their wood, the sash may be dispensed with, for the critical season will be past. An excellent plan for groi/ing rare species is to sow the seeds during the autumn in boxes of light, sandy loam, that is entirely devoid of any stimulating manures, care being taken that the seeds are placed thinly over the surface and not covered too deeply ; also that the boxes have perfect drainage. By placing them under the staging of a cool green-house, and keeping them moderately moist, but never wet, the young plants will make their appearance quite early in the spring. Especial care is required at this critical period that the soil be neither too wet nor yet too dry; either extreme will prove fatal to the seed- lings. One year old plants may be set out in a cold frame, or planted singly in small pots, according to the rarity of the kind. The following process, as recommended by T. Meehan, Editor .of the Gardener's Monthly, we have thoroughly tested and found to possess unusual merits : " A common board frame is placed over a carefully pre- pared bed of light mould, and covered with shaded hot- bed sash. Under each corner of the frame is placed a prop, raising the bottom about three inches above the sur- face of the ground. The advantages of this contrivance PKOPAGATICXN". 35 will at once be appreciated when we consider that the most essential conditions in raising evergreen seedlings are to obtain a moist atmosphere, protection from the direct rays of the sun, and at the same time a free circulation of air through the plants." The satisfactory manner in which the above plan an- swers all of these requisites, the small amount of labor, and little expense attending it, should recommend it for general use. CUTTINGS. — We are aware that cuttings of some species of plants root very readily, and others cannot be made to grow with all the skill and attention that can possibly be bestowed upon them. The family of Conifers furnishes ex- cellent illustrations of both the above extremes. We have noticed trimmings of Siberian Arbor Vita3 that had been thrown into the rubbish heap, rooting in the refuse mass, and forming young plants without any artificial help ; but on the other hand, the Pines are exceedingly difficult to propagate by cuttings, even under the most advantageous circumstances. Occasionally we find instances in the same genus, as for example among the Junipers, where some of the species are propagated by the thousands from cuttings, with little or no artificial heat, and yet others invariably refuse to root under the best systems known to gardeners. Among the Abietinem^ the Pines are perhaps the most difficult to increase by cuttings ; the Larches will grow rather more easily ; the Cedars are more tractabl e still ; and the Spruces, with some few species of Firs, the most easy of the sub-order. The Cunninghamia is not very difficult to increase by cuttings, but the Araucaria we find very stubborn. In the Cupressinece, all the members root more or less readily. Commencing with the American Arbor Vitse which is the easiest of all Conifers to root, we next rank the greater portion of the Junipers. The Chinese Arbor Vitae, (Biota,) of which the golden variety is a fair exain- 36 THE BOOK OF EVERGREENS. pie, requires more heat, and our best propagators very frequently lose a large proportion of their cuttings. The Thuiopsis strikes quite readily. The Cypress, Japan Cedar (Gryptom&riaJ) Mammoth Tree (Sequoia,} and Libo- cedrus, are quite uncertain, — some seasons giving us a few young plants, but more frequently failing badly. In the Taxinece, or drupaceous-fruited Conifers, the propagator has a wide and interesting field for experiment, as they can all be grown from cuttings with varying suc- cess. The Yews, ( Taxus^) are grown, if given reasonable care, with possibly one exception, — the Taxus adpressa. The Torreya, Cephalotaxus, Dacridium, and Podocarpus, are rather more easily rooted ; and the Salisburia, (a de- ciduous-leaved genus,) may be increased with profit if sufficient care be exercised. In every genus, however, there are always some species more tractable than others, although depending in a great measure on the state of the atmosphere where they are grown, the requisite amount of heat, humidity, etc. This can only be ascertained by trial, as it varies according to circumstances. As a rule, all plants having variegated leaves are diffi- cult to manage; for, whilst the Siberian Arbor Vitae roots by mere contact with warm and moist earth, the varie- gated-leaved varieties with the best of care rarely ever succeed. To this statement, however, we find one excep- tion, as the variegated Yews form roots much sooner, and with less attention, than any others of the sub-order Taxinece. So also we find in the same immediate genus a curious problem to solve. The Abies Menziesii roots very easily, and the A. Douglasii and A. Canadensis act just the reverse. The Biota Orientalis is not very difficult to propagate, but its variety, pendula, is most certain to "damp off" and die. The Irish Juniper is quite easy to manage, and yet the Chinese species will scarcely ever succeed under the best of treatment. Picea Fraseri is exceedingly sensitive of the moist sand, but its PROPAGATION. 37 variety, Hudsonia, roots without trouble ; and so on we might multiply cases, but the above sufficiently exemplify our meaning. We now notice the structure for producing the condi- tions to ensure success. In erecting a propagating house, that heated by hot water has been usually considered best adapted for evergreens. It not only gives us a more even temperature, but it is always charged with moisture, and this the evergreen cutting particularly enjoys ; but an ex- cess of humidity must likewise be carefully avoided, to prevent " damping off," an evil serious in its nature and greatly to be dreaded. We merely desire sufficient moist- ure to overcome the frequently dry atmosphere of an ar- tificially heated apartment. In the case of hot air flues being used for heating pro- pagating beds, it is advisable to introduce pans filled with water, to supply the necessary humidity, and as this heat- ing arrangement is more cheaply constructed than the hot water tanks, many intelligent gardeners are dispensing with the latter altogether. In either case, it is desir- able to have the least amount of sand that can be used without actually allowing the base of the cutting to touch the boards of the cutting bench. Those who have not the more modern conveniences for striking cuttings may succeed reasonably well in a com- mon hot-bed ; the cuttings are first placed in boxes of sand early in the season, and then allowed to stand for some time in a cool place previous to applying the bottom heat. This method may do for the Arbor Yita3s, and some few others that form roots easily. Siberian Arbor Vitse, as well as the Tree Box (not a Conifer,) will often succeed in the open air in a moist, shady spot ; but this cannot be relied on every season, and never sufficiently to repay the commercial grower. In preparing the cutting for use, there is one important point frequently overlooked by propagators, and that is to 38 THE BOOK OF EVERGREENS. use ripened wood only. We have often — we may say very generally — noticed after a few weeks' insertion quite a number of the Irish Juniper cuttings, for instance, turn- ing yellow, and the lower portion in a state of decay. This is almost always attributed to the use of unripe wood, and consequently the open spaces in the beds might have been in a great measure avoided by throwing such weak succulent growth on the brush heap. Cuttings are generally prepared too small. We prefer them large and vigorous, with all the immature tips removed down to the ripened wood ; the latter being easily distinguished by the light-brown color of the bark, whereas the younger and unripened shoots are of a pale yellowish-green. The cutting with a heel, Figure 2, is perhaps the best, and should always be selected when the subject is difficult to manage; but in growing the easier kinds, such as Arbor Vitses and Junipers, it is un- necessary and expensive. Although opposed to all good rules, and calculated to encourage neg- ligence in the young gardener, yet the practice of carefully taking off every leaf on the lower end of the cuttings of Irish Junipers is super- fluous, and maybe avoided where time is every- thing to the energetic nurseryman. We have always been careful to have every leaf cut off as smoothly as possible, and never to allow a rough or jag- ged edge to appear on any part of the cutting ; but we feel bound to confess that the best strike we ever saw was in a bed of cuttings prepared in a very careless man- ner, by merely placing them on a board and drawing the blade of a knife close along the stem, severing at one cut all the leaves. Nevertheless, we believe too much care cannot be exercised in making a smooth, clean cut at the base of the shoot, and we always desire the knife to be as sharp and smooth as possible. Most propagators make this lower cut squarely across the wood, but we prefer PROPAGATION. 39 it to be slightly oblique, as shown in Figure 3. Some Conifers have long Recurrent leaves, adnate to the branches ; or, in other words, the base of the leaf is prolonged, and adheres tightly to the shoot for some distance from the point of insertion. When instances of this kind occur, we make the lower incisions directly beneath two opposite leaves, as in Figure 4. This method is especially applicable to the Cryptomeria, etc. Figure 5, A, represents a cutting of Juniper ready for placing in the sand of the cutting bench. Different species of evergreens often require en- tirely opposite systems of management during the rooting stage, particularly in the degree of heat necessary to cause tile formation of roots without injury to the cutting. The Golden Arbor Vitae will perhaps endure a higher temperature than any other; also, Cupressus Lawsoniana, C. Nbotlcaensis, and some few others, like a warm place. Junipers do not relish so strong a heat, but will passively endure it, whilst the different American Arbor VitaBS always succeed best in a temperate atmosphere. How- ever, all evergreen cuttings should be brought forward by degrees, and the heat raised very gradually in all instances. A sudden change from cold to heat often proves disastrous. The process of rooting commences first by gran- ulation, or callusing, which is followed by the roots and leaves almost simultaneously developing themselves. It. is therefore of primary importance that the cutting should form its granulation before the process of vegetation be- comes active ; and this is only accomplished by allowing it to be in a cool temperature, for a short time previous to being forced. The callus at the base of the cutting is shown in Figure 5, .#, and in (7, of the same figure, the roots have commenced to form. THE BOOK OF EVERGREENS. Fig. 5. — PROPAGATION BY CUTTINGS. — A, CUTTING PREPARED; B, THE SAME CALLUSED ; C, THE ROOTS FORMING. PROPAGATION. 41 The most successful method of striking cuttings of the Conifers is as follows : During the callusing season they should be preserved cool, and the buds prevented from swelling ; but when the action of the sap forces the growth of the cutting, the atmosphere must be kept moist and warm. The waterings and syringings should also be frequent, but care must be taken that the drainage is per- fect ; otherwise, they will assuredly rot. The callusing process, which soon ensues after heat is applied, is no criterion that the cutting is about to root, as they will frequently stand for two years in a perfectly quiescent state ; the large, spongy excrescence at the bot- tom gradually enlarging until it has to be removed alto- gether. The Yews are striking examples of this peculiarity, especially the T. adpressa ; and, therefore, for the pur- pose of assisting Nature in her endeavors to form these secondary roots, we remove a portion of the uncouth callus by making a smooth perpendicular cut through the mass, and frequently roots will then emanate from the cut edges in a short tune. Evergreens are sometimes grown from what are termed " soft-wood " cuttings, that is, the young wood in a grow- ing state. These are rarely successful if taken from a plant growing in the open air ; but when the old plant forms its new growth under glass, the shoots are then suitable for the operation, and the method is certainly desirable for increasing our stock of new and rare trees. The Lawson's Cypress, which is extremely difficult to grow by the usual mode, succeeds tolerably well under this treatment. The proper season for preparing and setting evergreen cuttings is during the months of October and November, leaving them cool and passive until severe weather sets in, when the heat may be gradually applied until the necessary degree shall be attained. In conclusion we desire to add, that as the foregoing sketch is intended only as a guide to the beginner, he will 42 THE BOOK OF EVERGREENS. soon learn very many little ideas in connection with the business which cannot be found in books. Application and energy are the most valuable assistants, and with these he will soon become expert. LAYERS. — As this method is so seldom practised on ev- ergreens, excepting to increase the dwarf, trailing species, or an occasional limb on the taller kinds, it is not neces- sary to devote much space to its discussion. The usual mode of layering deciduous plants is also practised on these ; and as an additional inducement to cause the forma- tion of roots, we would advise, a slight covering of ever- green branches as a protection from the sun, and to pre- vent a too sudden evaporation of moisture from the soil. A sudden twist will answer the purpose of checking the sap much better than the usual method of tonguing. As a rule, most plants with variegated leaves are difficult to strike from cuttings, so that we are obliged to resort to other modes. In such cases pots or boxes may be elevat- ed to a level with the branches that we desire to operate on, and the young shoots be layered in them, bearing in mind that they will frequently require attention to prevent the soil from becoming too dry. A protection must al- ways be given them, as mentioned above. GRAFTING. — As a means of reproduction among ever- greens, grafting is the most difficult and least certain plan in use. In the moist, even temperature of France and England, it is prosecuted with great success ; but our va- riable climate prohibits the use of it to any great extent. Under glass, where the temperature can be regulated to suit the operation, grafting, in some cases, is expedient. It should always be borne in mind when selecting stocks, that some species in a genus are more closely related than are others. For instance, the pines are generally di- vided into groups, and each group has particular charac- teristics, or idiosyncracies, that bind them together. Taking the White Pine (P. Strobus) as an illustration, PROPAGATION. 43 we find that this and the P. excelsa, Pt Lambertiana, P. monticola, and others, have many peculiarities in common. They have each live leaves in a sheath, and are similar in appearance. Their cones are long, with the scales not thickened at the apex. The habit of the trees is also much alike. The White Pine serves as a stock for all these. So with the Scotch Pine, (Finns sylvestris), which is suited as a stock to the related species P. Banksiana, P. pumilio, P. pungens, and others. The following method for grafting evergreens we have practised for several years, and con- sider it the most certain and easily performed. Having, during the pre- vious autumn, potted the plants to be used as stocks, and wintered them in a cool frame, they may be gradually forced into growth to- ward spring. When the buds commence to swell, the plant is in a suitable condition for the operation. 6. — GRAFTING EVERGREENS. In all cases the graft should 44 THE BOOK OF EVERGREENS. be perfectly dormant, and the stock in a slightly growing condition. Having prepared the scion by smoothly cutting the lower end into a wedge-shape, the incision is then made in the side of the stock with a clean, smooth, downward cut. In placing the scion in the incision, particular care must be taken that the bark of each exactly corresponds. The grafts should be tightly fastened by strips of bass bark, or soft woollen strings, and the whole wound completely covered with grafting wax or waxed paper. This kind of grafting is shown in Figure 6, the tying material being omitted in order to show the manner of making the cut. The plants must be placed in a cool, shady situation for about two weeks, and then gently forced on a mild hot- bed with the glass shaded ; always keeping up a moist at- mosphere by frequent syringing. The pots should be frequently ex- amined to prevent excessive dry- ness, or the opposite extreme, either being exceedingly dangerous to the success of the operation. "When the grafts have started into growth, the strings may be cut, and in a short time the stock headed down. In the engraving, Fig. 6, the branches of the stock are represented as cut off, merely to take up less room on the page ; it is only when the graft shows that it has formed a union that the stock is cut back, and then it is separated by a smooth cut close to the point of insertion of the graft. The French practise grafting evergreens by using young, succulent wood ; but in this country success is much more certain with the foregoing plan. This herbaceous graft- ing is performed by breaking off the young, brittle wood of the stock a short distance below the terminal bud, and Fig. 7.— GRAFTING WITH NEW WOOD. PROPAGATION. 45 preparing the graft from the young and tender wood of the species to be propagated. The well-known mode of cleft grafting is then employed, and the plant shaded from the rays of the sun and heavy rains until the two are firmly united. Figure 7, from Dubreuil's Arboriculture, illustrates the operation. The wood, both in the stock and graft, should have acquired a little toughness before using, but should not be fully ripened. We have seen excellent success in grafting Arbor Yi- ta3S in the open air, by the common method of cleft graft- ing. The stock in this instance is headed down close to the ground ; and after performing the operation, the earth is drawn closely around, leaving the upper portion of the graft only above the surface. An occasional wetting will be sufficient to start it into action. Other methods are practised by gardeners, but differ only in minor details from these described. CHAPTER IV. PRUNING AND AFTER-MANAGEMENT. With fruit trees, "summer pinching, as well as limb and root pruning, are often resorted to for the purpose of pro- ducing fruitfulness ; but in the case of ornamental trees, pruning is seldom necessary, except to preserve a sym- metrical shape and to remove all unhealthy or dead branches. The entire system of pruning a Conifer depends very much upon the same principles that govern the trees of other classes, with the exception that almost every species of the Conifers has a tendency to the conical form, and this peculiarity should therefore always be encouraged during the trimming process. Many a cultivator, through a mistaken idea of beauty, utterly spoils his trees by pruning off the lower branches, and thus forming a long, naked body to the tree, most disagreeable to the eye of an intelligent planter. In pruning the branches of an evergreen, always select a strong bud to cut back to, thus allowing a chance for the limb to start apparently from the end bud, and thus pre- vent the artificial means that have been employed from be- ing observed. An excellent plan to preserve a perfect shape, is to extract the centre bud from any shoot that projects beyond the proper limits. The remaining buds will form branches which are induced to spread apart, and in a dif- 46 PRUNING AND AFTER-MANAGEMENT. 47 ferent direction from the one to which the leader or main shoot inclined. This method of extracting buds is also successfully followed to produce a more dense growth in many evergreens that are naturally of an open habit. Many of the upright growing Junipers as, for instance, e/i communi^, and its varieties, Hibernica, Suedca, etc., are greatly benefited by an annual pruning of the over-luxuriant bran chlets, thereby causing them to thicken, and otherwise vastly improve in appearance. When the leader or main stem of a Conifer becomes destroyed by accident or otherwise, a new one may readily be formed by tying up a lateral in as nearly an upright position as pos- sible. All of the species evidently endeavor to supply the loss either from a dormant bud, or, in many instances, from a prominent one on a side branch; but it is too often the case that two leaders will start and cause a distortion, which is often observed in so-called ornamental trees. The strongest should be selected to remain, and the others cut away as soon as noticed. When a tree is disposed to lean upon one side, a suitable contrivance to remedy the defect is to fasten one end of a strong wire to the main body of the tree near the top, and secure the other end to a stout stake driven into the ground a short distance off, taking care to wrap the body of the tree with some soft substance, to preserve the bark from injury. CHAPTER V. EVERGREEN HEDGES, Nothing,in our opinion, is so peculiarly attractive in a well kept place, as an evergreen hedge neatly and frequently trimmed; 'and nothing really injures the appearance of a place more than one that is neglected and allowed to grow at will. Either as an ornamental boundary, or for a protective screen, no class of plants can equal those with persistent or evergreen leaves. Always green and cheer- ful throughout the whole year, an impassable barrier to winds and storms, easily clipped, and remarkably beauti- ful when properly cared for, of rapid and dense growth, and comparatively free from disease, they comprise indeed nearly all the requisites needed for a hedge. True, they cannot be formed into a defensive barrier against the incursions of unruly cattle and the depreda- tions of the fruit stealer ; but in beautifying our homes and endeavoring to create additional attractions in their sur- roundings, we desire something more than the merely practical ; and we therefore insist that there can be no place, however small, but what may receive an added charm by the introduction of a neat evergreen hedge, such as we have described. Such improvements are invariably associated with good taste and refinement. Evergreen hedges may very properly be divided into two distinct classes, which, in the planting, selection of varieties, and after-management, differ very essentially 48 EVERGREEN HEDGES. 49 from each other : first, those intended strictly for shelter or to conceal unsightly objects ; and secondly, the true ornamental hedge. The former requires less care, and is intended mainly for the unfrequented portion of the grounds, and very frequently needs no attention, excepting an occasional clipping of the stronger branches and a head- ing-in of the taller plants. What is needed more particularly in a screen or barrier to break the force of storms, is a strong growing, hardy species that is not easily affected by the wind, and such we find in the hardier class of Pines and Spruces ; as the White, Scotch, and Austrian Pines, and Norway Spruce. Although we find the common Red Cedar (J. Virgini- ana), Chinese Arbor Yitse (JSiota orient alis), and the common Juniper (Juniperus communis), occasionally rec- ommended for this purpose, we are compelled to discour- age their use owing to their unfortunate habit of dying out near the base, and thus disfiguring the symmetry of the screen as well as opening a passage for the cold winds. This may not be the case throughout the West, and indeed Dr. Warder, in his work on Hedges and Evergreens, maintains the contrary opinion; but in the Eastern States we have frequently noticed this drawback to their culture. The late William Reid, of Elizabeth, K. J., than whom no more skillful hedge-grower could possibly be found, stated to the writer that these plants would never answer the purpose, and that after several years of patient trial he had entirely given them up. The American ArJ^or Vitae ( Thuja occidentalis) affords an excellent protective screen, in a small place ; but on an extensive scale, we prefer the Pines and Spruces. The true ornamental hedge, to please the eye by its sym- metrical proportions, and richness of color, should receive a full amount of care and attention, for the neglect of one season will very frequently cause it to become disfigured 3 50 THE BOOK OF EVEKGREENS. to such a degree as to require several years to rectify the damage caused by the reraissness. After determining the location for the hedge, the ground should be plowed or dug deeply, about four feet (or even more) in width, and the plants set along the centre of the pulverized strip. The proper distance apart for the plants will be determined in a great measure by their size and the species used. We prefer the height from 12 to 15 inches for Arbor Yitse, Hemlock, and other plants of me- dium and slender growth. In large screens, this distance must be modified, and the plants set three, four, and even a greater number of feet apart, according to the required density of the screen. Nothing further is needed during the first season than to trim off the tops of the larger plants, or an occasional side shoot, that projects out further than the main portion of the hedge. Always bear in mind that the ground must be kept scrupulously clear of weeds, and be frequently stirred. Mice very often attack a neglected hedge, but very seldom a clean, well cultivated one. In stirring the soil, the hoe or cultivator should not run so deeply as to destroy the numerous small rootlets with which the ConiferaB are so abundantly furnished. "We usually scat- ter a slight dressing of well-rotted manure over the sur- face of the soil during the winter, and thus at the same time protect the roots and furnish nutriment for the ensu- ing season's growth. The second year the plants ought to make a reasonable growth, and a clipping during the summer will be requir- ed in addition to the regular autumnal shearing. If in- clined to grow strongly, a frequent trimming will be ben- eficial, as it should always be the aim of the cultivator to produce an impenetrable mass of foliage, especially at the base of the hedge. The requisite shape should also be given as soon as circumstances will permit. "We prefer the curvilinear form for many reasons, the EVERGKEEtf HEDGES. 51 most practical of which is its ability to shed a heavy weight of snow that would otherwise adhere, and, by pressing out the side branches, mar the beauty of the hedge. Novices must always bear in mind that it is very easy to produce a tall hedge, but to form one with a close, broad bottom, requires frequent trimming, and a proper amount of attention ; for after the hedge is grown, this can- not be accomplished. In after years, when the hedge ar- rives at its required height, all that will be necessary is the frequent use of the shears, and due attention to keep the weeds and other strong growing plants clear from the row. SEASON FOR PRUNING CONIFERS. Many intelligent cultivators utterly disregard all set times for performing this important operation, under the belief that the best season to trim is when they have the most time to devote to it. There is, no doubt, an advan- tage to be gained by this course, but there are principles that govern this operation, as well as those of planting, propagating, etc. In a young hedge, for the first two or three years, we do not desire to trim severely, as the object should be to encourage, not weaken the growth, and consequently our own practice has been to cut them but once in the season, say in October, and when the young shoots have ripened, but not by any means after freezing weather sets in. One main reason for not pruning late in the autumn is, that after the external portion of the hedge is removed, the inner and weaker parts are then exposed, which, being in a very tender state, are liable to become injured by evaporation and sudden changes of temperature. In an older hedge, the object in pruning is to weaken growth, and this is best gained by pruning early in the month of June. At that season the unmatured shoots are suddenly checked by being cut back, and the growth weakened very mate- 52 THE BOOK OF EVERGREENS. rially in consequence. A second trimming is also given the hedge in October, to bring it into shape. The same principle governs the pruning of specimen evergreens. When we wish to weaken the growth, trim the young shoots early in the season ; but on the contrary, if we desire a stronger growth, cut back in the autumn after the shoots are ripened. Observation and practice will soon teach the operator many facts in relation to this subject that cannot be learned in any other way, as much depends upon the ob- ject we desire to accomplish. CHAPTER YT. DISEASES OP CONIFERS. The diseases incident to this order of plants are compar- atively very few, and, as a general rule, mostly confined to a few species, and restricted probably to certain condi- tions of the atmosphere and soil. The causes that influ- ence the appearance and dissemination of a portion of these evils are not at present sufficiently understood; nevertheless we will give the most approved views on the subject, hoping thereby to induce more careful experiments which shall tend to counteract the direful effects of at least a part of these maladies. As already stated, a rich soil abounding in organic ma- nures, is, no doubt, one of the chief causes that produce unhealthiness in coniferous trees, by inducing a strong suc- culent growth which rarely allows the young tree sufficient time to mature its wood, and consequently, if not killed by the severe cold, it very frequently becomes in a man- ner diseased, and after lingering a few years ultimately dies. Another source of disease, and one also to which we have already called attention, is that of an imperfectly drained soil. Disease often occurs to the tree from this very simple, yet baneful cause, which will eventually de- stroy its life, although oftentimes it may linger for several years, gradually, though surely, approaching its death. There is no doubt that three-fourths of the diseases com- mon to this family arise from the two causes just alluded to ; an unhealthy condition is indicated by the appearance 53 54 THE BOOK OF EVERGREENS. of moss, lichens, and numerous fungi on the bark, but these are undeniably the effect, and not the cause, thereof. We frequently find evergreens making short annual growths and losing the foliage on the young wood, or, per- haps, the bark is covered with lichens, and the leaves with minute parasites; yet the primary cause that produces this state of unhealthiness is not apparent. To counter- act these diseases, we must consequently commence at the foundation and search for and remove the cause, when all the outward forms incidental thereunto will surely dis- appear. Among the most mysterious causes of death in the Con- iferae, is that of blight, which has heretofore been gen- erally confined to the White Pine, (JPinus fitrobus,) and a few allied species. So insidious is its approach that we scarcely have become aware of its presence before the tree is lost. Plants that are to all outward appearances per- fectly healthy, suddenly turn yellow, the foliage whitish, and death in a very short time ensues. This is the more trying, as other plants closely adjoining still continue to thrive luxuriantly, and by their rich, dark green foliage lull us into fancied security, and then perchance fol- low the course of their departed companions in a few weeks. The requirements of the Sir obi group of Pines differ widely from those of any other, and demand certain conditions in the soil, to prevent disease and promote a healthy growth. They will not succeed in a wet, undrain- ed situation ; but if light and dry, their future success may safely be depended on. The most rational cause that we can assign for the ap- pearance of blight in the family of Conifers, is that due to a too luxuriant growth. One of the newer diseases prevalent among evergreens, and one from which the Stroll group of Pines is singu- larly and entirely exempt, manifests itself as follows : Early in the autumn a few minute spots are noticed at the DISEASES OF CONIFERS. 55 apex of the leaves, which gradually extend downward to the base, until they cover almost the entire surface. The leaves finally become so diseased as to fall off, thus leaving a long, bare branch, either completely destitute of foliage, or occasionally with a small tuft of reddish-brown leaves at the extremity. We have noticed that until very re- cently, trees growing on low, damp grounds, where there was imperfect drainage, were always attacked first. Es- pecially was this the more clearly shown in nursery rows, where we would observe a few trees standing in a spot where, during winter particularly, there was stagnant wa- ter about the roots, and whilst these trees would be gradu- ally dying with this mysterious malady, others in the adjoining rows would be perfectly free from its effects. Within the past year, however, this disease has become less fastidious in its selection of situations, and has assum- ed more of the character of an epidemic, spreading to trees that were growing in soils exactly the opposite in nature to the above. We have lately observed its appear- ance on a number of Pinus Austriaca, and P. Laricio, standing on a dry, gravelly hill-side, where the surface had been washed away by the heavy rains. To these two extremes of unsuitable soils this disease is almost entirely confined, and rarely can it be observed in such pines as are growing in well prepared ground. After having examined and patiently studied this un- healthy state of the tree, from the first intimation of dis- ease through its various stages until death ensues, we are obliged to admit that we cannot make any positive state- ments in regard to its cause or eradication. In the disease under consideration, small spots are perceived on the leaf of the Pine, which spread rapidly until they cover the whole surface. Under a good lens, these spots are discov- ered to be a very minute fungoid plant, which, finding a suitable condition for its growth, speedily destroys the 56 THE BOOK OF EVERGREENS. leaf. As all vegetable productions when in a perfectly healthy state, are free from the numerous parasitic growths that are common to diseased plants or trees, therefore, when any appearance of the lower order of Cryptogamia, such as fungi, mosses, and lichens, becomes visible, some- thing must be assuredly wrong in the functions of the plant itself. This parasitic vegetation is not the primary cause of ill-health, as some imagine, and hence the mis- chief is performed before these outward forms become ap- parent ; and although these are charged with being the prime instigators, they are in reality but the effect of dis- ease previously contracted by the tree. The species that we have found to be most easily af- fected, are the Pinus Austriaca, P. Laricio, P. Pyrenaica, P. Pallasiana, with perhaps a few others ; and in every case the diseased trees were members of the two-leaved group of Pines. The disease known as Etiolation, or blanching, entirely destroys the verdure of plants, and renders them pale and sickly. This arises from an insufficiency of light. It is mostly observed on such plants as are growing in the dense shade of trees ; but may occur from a variety of causes, such as insects nestling in the rootlets and consum- ing the food of the plant, thus debilitating the leaf so as to render it insusceptible to the action of the light ; or the same appearance may arise from extreme poverty of the soil. It is not prevalent, and in the majority of instances may be easily detected and remedied. Gangrene, however, is of a different nature, and is mostly confined to the half-hardy plants, or such as are easily affected by sudden changes of the atmosphere. It is mainly attributable to two causes, the one arising from an excessively high degree of temperature, the other, from extreme cold. A very low temperature destroys or shrivels the .green leaves and shoots, turning them to a dark DISEASES OP CONIFERS. 57 brown color ; and so will excessive heat destroy their vi- tality. A too rapid growth of a particular branch will very frequently deprive the one adjoining of its due share of nourishment, and death ensues. Again, certain winds have a disastrous effect on the young shoots ; or the early frosts of spring deprive them of life. CHAPTER VII. INSECTS INJURIOUS TO CONIFERS. Coniferous trees have some insects peculiar to themselves, and they are also preyed upon by those that are found as well upon a number of deciduous trees. We shall briefly describe the most troublesome of these, and give some hints towards ridding our collections of these destructive pests. The Drop-worm, or Basket-worm, ( Oiketicus conifer- arum, of Harris; or Thyridopterix ephemcereformis. — The larva of this in- sect surrounds itself by a case,or "basket," constructed of the leaves of the trees on which it feeds. These cases are very tough, and likewise difficult to displace from the twig to which they are at- tached. Fig. 8 shows the case, and Fig. 9 the larva removed from it. When feed- ing, the worm fastens its curious little house to a twig by means of a few silken threads, which are removed and refasten- ed at pleasure. They will also drop from one limb to another by means of these threads, and commence their work of destruction in a fresh place. This terrible little pest, now be- coming so well known in this country, was only discovered here a comparatively few years ago, and the above name was given it by Prof. Harris. Although his description would lead one to infer 58 INSECTS INJURIOUS TO CONIFEEJ3. 59 that it confined its ravages to the Conifers alone, it never- theless depredates severely on many of the deciduous trees. It is particularly troublesome on the Arbor Vitaes, and in a very short time will completely demolish every vestige of foliage on the plant. We have also seen its silken cases very numerous on the Larch and the Decidu- ous Cypress, as well as on the Plemlock Spruce. The little insects are exceedingly numerous, and rapidly multiply if not destroyed when first observed. The young worm is quite timid, and upon the least noise or disturb- ance of any kind, immediately withdraws into its cover- ing, which closes up tightly at each end, thus securely pro- tecting it. The female is without wings, and never leaves her chrys- alis until her approaching dissolution, which takes place after depositing her eggs in this singu- lar, basket-like case. The male moth is at least J inch in length, of a dark brownish color, and is extremely shy and impatient of confinement. Its ordinary shape is shown in Figure 10 ; it has the power of extending its abdomen after the man- ner of a telescope, as seen in Figure 11. Immediately upon hatching, early in the spring, the little worms scatter over the sur- rounding foliage, and each soon pre- pares a little basket for itself, which is enlarged as its occupant needs more space. The only method of eradicating them is to pick the nests, or baskets, off by hand, and dc- stroy them by burning or otherwise. Galls* — We have noticed, of late, curious resinous galls or excrescences on the ends of the shoots of some Pines, and particularly on the Scotch Pine, which may possibly belong to the Tortrix, or some allied genera. Its manner 60 THE BOOK OF EVEEGEEENS. of living is very similar to that of the Orthotcenia.resin- ella, of Linnaeus, a European moth, described and figured in London's Arboretum, Vol. IV, page 2146. As no cer- tainty has been arrived at in regard to the correct nomen- clature of this species, we are unable to pronounce it new, although Kollar, Harris, Fitch, etc., evidently do not de- scribe it. In particular seasons and localities they become quite numerous, and large numbers of these resinous balls may be noticed, always on the extreme end of a main branch, or frequently and disastrously on the main shoot of the tree. The eggs are deposited at the base of the bud, and the worm bores downward for some distance in- to the branch. These gall-like excrescences are caused by the exuding resin, and often increase to the size of two inches in diameter. The moth is usually quite small, of a dull lead color, with broad, entire, fore wings, which form a triangle with the body when at rest, slightly deflexed at the sides and dilated towards the shoulders. The only plan to destroy them is to examine these ex- crescences early in the autumn and dislodge the worm, or, if left until spring, the shoot should be cut away and burned. Plant-lice. — The family of Plant-lice, or Aphidce, are mostly so minute as to be scarcely perceptible to the nak- ed eye, and yet they frequently appear in such immense numbers as to destroy the plants in a short time. These insects cause the foliage on the younger twigs to curl up tightly, and may on this account be very readily detected. Prof. Stauffer, of Lancaster, has detected an undescribed species feeding on the Norway Spruce. Its proboscis is much longer than its body. Another species has lately been found with a shorter proboscis, and differing very es- sentially from the above. A third species, and distinct from both the foregoing, has a woolly appearance, and is found on. the branches . of .evergreens. In England, the INSECTS INJTJEIOTJS TO CONIFERJ2. 61 Aphis juniperi is mentioned as infesting the various Juni- per as well as a species of Thrips (Thrips juniperi.) To completely destroy these little insects, it is only necessary to drench them well with a solution of whale-oil soap or tobacco water. Perhaps the best and most convenient remedy is hot water a few degrees below the boiling point, which will not injure the plant but effectually destroys these pests. Scale-Insects. — The Scale-insects are occasionally found on some of the Conifers, and more particularly on many of the Junipers. In fact, so injurious are they on some specimens, even of a large size, that we have known the plant to be killed in a single season. They will attack the leaves of pines, particularly if the tree should be in an un- healthy condition. These insects are the most formidable enemies we have to contend with, owing to their peculiar habits. The visible token by which we recognize the presence of these pests is the scale-like covering ; this is in reality the relics of the parents which remain to act as a protection to the young brood ; these extract the juices from the tree beneath their tough covering, and kill it gradually. As we cannot apply to the scale any of the various solu- tions that are employed in killing the Plant-lice, it becomes necessary to scrape them off; and here again another diffi- culty arises, — for among the multitude of closely imbricat- ed leaves found on the Junipers, this plan is absolutely impossible. The hot water remedy with us is first tried thoroughly, and if that fails to remove these tough little coverings, we proceed to the final resource, that recom- mended by the old Dutch farmer for killing off the curcu- lio, i. e. "Cut the trees down;" only in our case it has the recommendation of preventing the insects from spread- ing to other trees in the vicinity. The Pine-leaf Scale-insect, (Aspidiotus pmifolia), is 62 THE BOOK OF EVERGREENS. a new species discovered by Fitch, that preys upon the leaves of the Pine genus, and is very distinct from the scale that infests the Junipers. An insect, new to the writer, has made its appearance during the past season in large numbers ; and although very readily destroyed, it may nevertheless become a great nuisance if not promptly attended to when first observed. They are pale yellowish-green caterpillars, about an inch in length, and feed in communities ; in fact, so voracious are they, and so very numerous, that frequently they will clear a young pine of all its foliage in two days. The Dwarf Pine appears to have their preference, although we have met with them on the Scotch, Loblolly, etc. A plen- tiful deluge of hot water, however, quickly destroys them. Colcoptera. — We have lately received the following brief but interesting list of " Coleopterous Insects " infest- ing the Conifers, from Prof. S. S. Rathvon, of Lancaster, Pa., all of which he states have been found in Lancaster and York Counties, Pa., or in Virginia and Maryland, around Washington City, and a few farther north. " The trunks and roots of some pines (P. Strobus, P. rigida, etc.,) are often attacked by small white grubs, al- lied to the common grub of the May-beetle, and will al- ways be found lying on their sides in a semi-circular form. This is especially the case when these parts are aifected with decay, although I am not prepared to say that they are the primitive cause of it. These are the larvae of a small Melolonthon, called the c Bristle-necked Valgus ' by Dr. Fitch, Valgus seticallis, Brauv. The Valgus serrical- Hs also attacks the pine, particularly the roots. The lar- vse of Chalcophora Virginiensis, a rough-bronzed beetle, nearly an inch and a half long, attack the trunks of pines. This insect belongs to the Buprestidm, the larvse of which are long and flattened, having the anterior segments much developed, in shape something resembling a newly-wrought INSECTS INJURIOUS TO CONIFERS. 63 horse-shoe nail. Also other species of the same genus, C. immaculata j C. liberta / C. novaboracensis, etc., etc. " In May and June, on the Pine and Spruce trees, the Chrysobothris Harrisii and the Buprestis aurulenta ap- pear, (the latter a beautiful green and bronzed beetle), the Iarva3 boring into the trunks of those trees. There is also the JSuprestis fulvoguttata, and the Dicerea punctulata, which particularly affect the Pinus rigida. The Bupres- tidce are spindle-shaped insects, tapering most towards the hind end, all more or less bronzed beneath ; and the larvse of all of them very similar in shape, white fleshy worms with small or rudimental feet, and a small black, or brown glossy head. Monohammus notatus, a ' Long-horned bee- tle,' in the larva state, bores transversely into pine timber at least, and is also found in decayed or dead parts of standing and living trees. " The Iarva3 of some of these ' Long-horns ' much resem- ble those of the JBuprestans, only they are not so thick in front, and do not narrow so suddenly into the nail, or tad- pole-shape. Also the M. titittator, M. marmoratus, M. scutellatus, etc. ; this last named species being more abund- ant on the northern border of our State, (Pa.) " Among the Longicornia, infesting the different kinds of pine, are also Eupogonius pinisora ; Leptostylus com- mixtus ; Euderces pini ; Callidium antenuatum ; Hylo- trupes bagulus y Orthosoma Pennsylvanica^ (a large, long, brown beetle) ; Tragosoma Harrisii ; Rhagium lineatum ; Tomicus xylographus, nigricalis, niger^ et fulvus, et caligraphus, et pini, et pusillus^ et mater iarius, etc., etc. Then we have Hylurgus tenebrans ; Hylastis pinifex, et carbonarius ; JETylobius pales, et picivorus, etc. All these insects, both in the larvae and perfect state, affect the pines immediately under the bark, or in the wood of the trunk and large limbs. "Affecting the twigs, is the Pissodes strobi, a small, black { Curculio ' ; but then there are also species belong- 64 THE BOOK OP EVEEGEEENS. ing to the Hymenoptera and Homoptera, which affect the leaves as well as the twigs. There are also Lepidoptera which do the same, especially the Toricidce. In addition to the aforenamed Coleoptera, the following affect the leaves : CTvrysomela Philadelphia ; Grtyptoscellis hirtus / Dichdonycha albicallis ; Anomala pinicola ; and Met- achoma 6-notata. Liopus facetus^ and Hylurgus dentatus^ on the Cedars and Junipers." There are other insects infesting the Conifers in this country, but not sufficiently numerous to require special notice. For instance, in the Southern States, Michaux mentions extensive tracts of the finest pines covered only with dead trees, caused by swarms of small insects (prob- ably Hylopius pales) which lodge themselves in different parts of the stock, insinuate themselves under the bark, penetrate into the body of the tree, and cause it to perish in the course of the year ; but such instances as the above are, perhaps, only local, and occur unfrequently. CHAPTER VIII. SITUATION AND SELECTION" OF VARIETIES. In a pecuniary point of view, the planting of evergreens around dwellings is advisable, as they protect them from the violence of the storms, which trees with deciduous leaves, are unable to do during the winter months. This important view of the case has been very ably argued by Dr. Warder in his work on "Hedges and Evergreens," and certainly ought to be carried out in practise by our farmers generally. The above mentioned author, after showing conclusively the great saving that will thus accrue in the matter of fuel alone, recommends farmers to plant belts of evergreens around their barns and farm-houses, for the better preserva- tion of their stock from the inclemencies of the winter, and, particularly, for those living in the far West, on the vast prairies, these belts will, undoubtedly, prove highly economical and useful. In many instances, throughout England especially, Pine- turns have been .formed, composed entirely of all the spe- cies and marked varieties of this order. Where such is the case, we often find many half-hardy plants succeeding, that under ordinary cultivation obstinately refuse to be- come acclimated. This is entirely owing to the shelter which the larger growing and hardier kinds afford these natives of a milder climate. Some of the large English Pinetums contain specimens of all the rarer species, at the present time, of 65 66 THE BOOK OF EVEEGEEENS. fine size; whilst we, from some cause, are almost entirely ignorant of their very existence. In the United States, owing to the want of sufficient enthusiasm, or the need of pecuniary means, such a collection has never been at- tempted ; although there have been a few instances with- in the past few years where energetic individuals have de- voted much time to the subject, and have created quite creditable collections. To the general planter these specialties are of little in- terest, and excepting as mere botanical specimens, or for the purpose of testing every known species and variety, not to be recommended. The idea of this work is not to encourage an undue interest in the Coniferge to the exclu- sion of other trees, but to enable the uninformed planter to ma.ke a judicious selection, which should be systemat- ically planted as recommended by those who have made it a study and are best qualified to judge. The great diversity of form and color as displayed in this order is calculated, in the hands of a competent person, to create an impression that will always please the eye ; but, on the contrary, if undertaken by an unskillful hand, an incongruous mixture will be the result, that not only pains the eye of a person of taste, but in most cases will prove a mortification to the proprietor in after years. The desire of every owner of a plf^ce should be to plant his trees in such a manner as will harmonize with the nat- ural landscape, by a prudent admixture of the varied forms and shades of color. This, if properly done, will be a constant source of satisfaction to himself and others. We do not, however, wish to be understood as recom- mending a strict observance of the arrangement c-f trees in our woods; but we do sincerely desire to see a more natural and less artificial system pursued than that so frequently practised by many planters of the present day. In one of Bayard Taylor's works, he thus beautifully SITUATION" AND SELECTION OF VARIETIES. 67 alludes to the true principles of landscape-gardening : " In the forms and colors of the trees, and their disposition in regard to each other, and to the character of their back- ground, we detect that art which never appears as art, — never can offend because it is developed through the ordi- nary processes of nature. Plant a tree, and it will take, of itself, its own characteristic. Nature, however, can simply produce; she cannot combine and arrange. She will not plant yonder Weeping-ash on the slope, so that its outer boughs shall just touch the water ; she will not rear those Purple Beeches to relieve the huge green mass- es of the ancient Lindens, nor give the Silver Birch an airy lightness and distinctness by a back-ground of Pine. She plants weeds among the flowers, and ripple-grass in the turf; muffles the brook with autumn-leaves ; and fills the pond with sickly water-mosses." Many species appear to much better advantage when grown singly, to allow of a perfect development of shape, whilst others are beautifully calculated to form groups ; but in the arrangement of the latter, a guarded care should be exercised to prevent an unsightly, crowded cluster. Downing, in his " Landscape Gardening," says : " Noth- ing at first thought would appear easier than to arrange a few trees in the form of a natural and beautiful group, — and nothing really is easier to the practised hand. Yet experience has taught us that the generality of persons, in commencing their first essays in ornamental planting, al- most invariably crowd their trees into a close, regular dump, which has a most formal and unsightly appearance, as different as possible from the easy, flowing outline of the group. " Natural groups are full of openings and hollows, of trees advancing before or retiring behind each other ; all productive of intricacy, of variety, of deep shadows, and brilliant lights." The great value of evergreens for grouping consists in 68 THE BOOK OF EVEEGEEENS. the contrast exhibited between them and the round head- ed class of trees, so that, when two or three Pines or Firs are inserted in the centre of such a group, they produce a beautiful effect. A fine specimen of the Common Hem- lock Spruce, when planted on an open space, with generous cultivation, becomes the perfection of beauty in a tree. The rich, dark green foliage, and graceful drooping branch- es, waving and glistening in the passing breeze, create an impression of quiet elegance. A frequent error, and one utterly devoid of true taste, is that of planting trees in straight lines. We have in our recollection more than one lawn on which the trees are planted so strictly in right angles, as to remind one of a geometrical figure. In an orchard or garden of fruit trees, this system is expected, and indeed is proper ; but on a lawn, it should never be tolerated. Another erroneous practice is that of planting large-sized trees in small door- yards, without taking into consideration their ultimate size. There are a number of evergreens belonging to the smaller class of trees, or large shrubs, that would answer the purpose equally well, which would not grow out of proportion. No undeviating rules can be laid down to instruct the planter how to arrange his trees correctly ; but general principles may be given to prevent confused and meaning- less effects. To form plantations according to correct prin- ciples and carefully executed ideas belongs to the person of taste. We conclude this subject by one more extract from the writings of Bayard Taylor, in which he thus alludes most eloquently to the intelligent landscape-gardener: "In his eyes all its features are, to a certain extent, plastic. That which he cannot change or remove, he can throw into per- spective, or so conceal by the intervention of other forms, that its individual ugliness shall become a component part of the general beauty. To contracted spaces he can im- SITUATION AND SELECTION OF VAEIETIES. 69 part a character of expansion ; dead levels he breaks by picturesque interruptions ; he works not alone for the eye, but excites the fancy by stolen glimpses which hint at some concealed charm.

In order to present the genera described in this work arranged in their proper sub-orders, the following synopsis has been prepared. It is intended as an artificial key to aid in determining the genus to which a plant belongs, rather than as a scientific grouping of the genera. The number placed after the name of the genus refers to its position in the work. The characters of the Family are described at length on page 12, and we here give only a brief recapitulation of them: NATURAL ORDER CONIFERS,— THE PINE FAMILY.

Tha general characters of this sub-family are given in the Synopsis on page 70, and we illustrate them by a figure, (Fig. 12,) modified from Richard, of the flowers of the Scotch Pine, (Pinus sylvestris). A. cluster of sterile aments of the natural size is shown at #, and at b one of the aments enlarged ; the scales of which it is composed are stamens, the back of one of which is seen at d, and the front; showing the two anthers, at c. A solitary fertile ament at the end of a short branch is shown at e / f is the same enlarged; g is one of the carpellary scales, or open pistils, with its accompanying bract ; h is a view of the same, with the two inverted ovules at its base. These scales, in ripening, form the cone ; a separate cone-scale, with the seeds at the base, is given at i. I.— PINUS, Linnaeus.— PINE. Flowers, monoecious. Sterile aments, in spikes or clus- ters, formed of numerous stamens on the axis, with very short filaments. Anthers, 2-celled, with a scale-like con- nective, and opening lengthwise. Fertile aments, solitary or in clusters, and terminal. Fruit, a cone, persistent, and formed of woody imbricated scales. Seeds, nut-like, situ- ated in an excavation at the base of the scales, and mostly winged. Cotyledons, linear, from 3 to 12. Leaves, nee- dle-shaped, almost cylindrical, in clusters of 2, 3, or 5, with a sheath at the base ; persistent. The genus Pinus comprises a much larger number of species than any other belonging to the order. The 74 THE PINE SUE-FAMILY. 75 Fig. 12.— FLOWERS OF PINUS SYLVESTKIS, TO ILLUSTRATE TUB INFLORESCENCE OF THE PINE SUB-FAMILY — ABIETINE^E. 76 THE BOOK OF EVERGREENS. recent discoveries in Mexico by Roezel have added several to the already large list, and although none of these can in all probability be acclimated in the Northern States, very many of them will form highly ornamental trees for more congenial climates, particularly in portions of Eng- land and France. The derivation of the name of this genus is involved in uncertainty ; some writers asserting it is derived from the Greek pinos, signifying a Pine tree, whilst others contend it came from the Celtic pen, a mountain, the natural hab- itat of the family. The Greek pion, meaning fat, in allu- sion to the resinous oily matter produced, is also a deriva- tion mentioned by some authors. The first is probably correct. The different members of the genus are found all over the world, and in point of usefulness are unsurpassed by any other belonging to the order. The resinous secretions contained in the wood render it invaluable for fuel, especially where an intense heat is required. Vast quantities of Pitch Pine, (P. rigida,) and Red Pine, (P. resinosa,) are yearly consumed in this manner. The wood of the Yellow Pine, (P. mitis,) Long-leav- ed, or Yellow Pine of the South, (P. australis,) and White Pine, (P. tStrobus.) is exceedingly valuable, and forms the most important lumber in the markets of this country ; whilst that manufactured from the Scotch Pine, (P. sylvestris?) is celebrated throughout Europe. The important commercial products, such as tar, turpentine, rosin, etc., are principally obtained from the P. australis, and other kindred species. For ornamental purposes, many of the Pines are unsur- passed for beauty, and form magnificent conical trees that create an effect peculiar to themselves. The newer intro- ductions from Northern California and Oregon are perfect specimens of elegance, and as many of them have proven THE PINE SUB-FAMILY. 77 hardy in this latitude, we may derive great pleasure from their introduction. In our division of this genus into sections or sub-genera, we follow the excellent plan pursued by Loudon, and adopted by Gordon. SECT. I.— BITVJE.— Two LEAVES IN A SHEATH It P. Austriaca, Hoess. — AUSTRIAN PIXE. — Syn. P. Laricio Austriaca, JEndlicher ; P. nigra, Link. — Leaves, long, rigid, slender, incurved, sharply mucronate ; rich, dark green color, and from short sheaths. Cones, medium size, (2^- to 3 inches long,) conical, slightly recurved and light brown color. Scales, smooth and shining, with a dull spine in the centre. According to Gordon, the Austrian Pine " is found on the calcareous mountains in Lower Austria, Styria, Mora- via, Corinthia, Transylvania, and in the neighborhood of Mehadia in Banat." It forms a large, spreading tree, about 120 feet in height, and produces strong timber, which is extensively used in its native localities. This valuable tree, although of comparatively recent origin, being unknown in Britain previous to the year 1835, has gradually worked its way into public favor, un- til at the present time it ranks as one of the most popular species, and one of the few well-known Pines that are ex- tensively planted. The numerous, rough branches, are placed regularly around the tree, and impart a massive ap- pearance. The rather long, rigid, dark green leaves, are remarkably beautiful when viewed from a distance ; but on the other hand, a very close inspection reveals a coarse and rather rough character, that should prevent its use for planting in the near vicinity of the residence. The cones are very handsome, being regular in shape, and of a rich brown color, which is heightened by a pecu- liar glossiness on the surface. 78 THE BOOK OF EVERGREENS. The hardiness with which it stands our climate is also an additional claim for its extended use ; as in the coldest winters of our Northern States, and particularly in the most northern portions of them, specimens of this species succeed and thrive as admirably as the natives themselves. It also adapts itself to almost every soil and situation, but prefers a rich, light loam, with a well drained subsoil, and in such grows rapidly, and speedily forms a tree. Where the soil is retentive of moisture, and consequently becomes sour and soddened, we have seen this species succeeding moderately well, whilst the White Pine, (P. Strobus^) planted in the same situation, died outright. We desire to advocate the claims of the Austrian Pine for planting wherever a strong, hardy evergreen is desired to break the force of the wind from buildings or orchards; and in groups, or for avenues, in particular situations, it is one of the most available trees at our command. Taking into account its rapidity of growth and the certainty with which it will speedily produce an effect, owing also in a great measure to the peculiar prominence of its general outline, we consider it unrivalled for a newly planted lawn. 2. P, Banksiana, Lambert. — BANKS' OR GRAY PINE. — Syn. P. rupestris, MX. / P. Hudsonica, Lamarck. — Leaves from a very short sheath, one inch long, rigid, divergent, numerous, evenly distributed, and grayish-green in color. Cones nearly two inches in length, ovate-conical, recurved, hard, smooth, light gray color, with almost pointless scales. Seeds, very small, with long wings. This species, which is a native of our most northern lim- its of arborescent vegetation, generally forms a large, straggling shrub ; but in milder regions grows much larg- er, and will in favorable situations attain to the height of a small or medium-sized tree. In Canada, and northward to Hudson's Bay, the Gray Pine is frequently met with ; and even after all other trees have disappeared, this is oc- casionally seen growing about three feet high and strag- gling over the ground. THE PINE SUB-FAMILY. 79 Dr. Richardson, during his journey to the Arctic Seas, speaks of it as attaining the height of from 20 to 40 feet, and even upwards in favorable situations ; and also that he found it occupying dry, sandy soils. He describes it as forming an elegant tree, with long, flexible, spreading branches. Douglas, likewise, mentions it as forming good sized trees in the valleys of the Rocky Mountains. The timber is remarkably light, with a straight, tough fibre, and according to Dr. Richardson much prized by the Indians for building their canoes, and for other purposes. For ornamental planting, JSTuttall says, " it is prized in Great Britain; but with us, as yet, the appearance of pines is too plebeian, from their abundance and predominance throughout the barren and uncleared lands by which we are still surrounded." Notwithstanding the existence of this species has been known to botanists for a number of years, and with a knowledge that in England it makes a fine specimen under generous cultivation, we are scarcely aware of its being planted in this country, excepting by a very few enthusi- astic botanists, who desire to examine the habit of every- thing belonging to the order. Michaux, in his " Sylva," speaks rather disparagingly of its merits. After mentioning the supposed medicinal properties contained in the cones, he remarks : " If this property, which is said to belong also to the fruit of the Black Spruce, is proved to exist, it forms the only merit of a tree too diminutive to be of any other utility." From which assertion we differ, for Ave know of no other species that is apparently so well adapted for creating a peculiar effect in picturesque landscapes, as the one under notice ; and particularly in close proximity to wild, rocky scenery, when it may be allowed to grow as a low, strag- gling shrub, and thereby appear appropriate. Michaux certainly never saw it in cultivation, for London thus eulogizes it : 80 THE BOOK OF EVERGREENS. " As an ornamental tree, we think it one of the most in- teresting of the genus, from the graceful manner in which it throws about its long, flexible, twisted branches, which are generally covered throughout their whole length with twisted, glaucous-green leaves, with here and there a whorl of curiously hooked, horn-like cones. It is one of the hardiest of the Abietinese, enduring in the Floetbeck Nurseries 12° of Reaumur (5° Fahr.,) and therefore it may be safely planted in pinetums in the extreme north, not only of Britain, but of Europe." 3, P. Brutia9 Tenore. — CALABRIAN CLUSTER PINE. — Syn. P. conglomerate G-rcefer ; quoted by Lambert. — Leaves in twos rarely in threes, very long, slender, glabrous, wavy, spreading, about 9 inches long ; light green, cana- liculate above, convex beneath, serrulate on the margins, terminated by a small callous mucro ; sheaths about $ i"ch long, persistent, of an ash-brown color, membranaceous, entire round the tops ; guarded at bottom with a linear- lanceolate, revolute, bright brown, thread-like, ciliated scale (metamorphosed leaf.) Cones, sessile, generally in clusters, ovate, smooth, brownish, 2 inches to 3 inches long; cones truncate at the apex, flattish, trapezoidal, um- bilicate, smooth, obsoletely four-angled ; umbilicus, dilat- ed, depressed, somewhat hollow, ash-colored. (D. Don.) A large tree from the Calabrian Mountains, where, ac- cording to Prof. Tenore, it attains the height of 70 feet. It is remarkably spreading in its character, and the bright green foliage produces a beautiful effect. After testing its hardiness for several years, it may now be recommended as reliable and quite valuable in a collection of ornamental trees. Many authorities have at different periods been at a loss to determine the true position of this species, and have through an ignorance of its distinctive characters ranked it as a variety of P. pinaster, etc. ; and Spregel referred it to that species, without considering it suffi- ciently marked to even form a variety. It is, however, very distinct in many points. It so closely resembles the P. THE PINE SUB-FAMILY. 81 Ualepensis in general appearance, as to be frequently mis- taken for that species, although the latter is very uncertain in this climate. The fruit, however, is very unlike ; as that produced by the P. J3rutia is almost invariably borne in large clusters, and sessile; and the P. Halepensis produces its cones sol- itary or occasionally in pairs, with long footstalks, and likewise forms a smaller tree than the former. It is one of the foreign species to which little attention has been paid, notwithstanding its merits fully entitle it to the attention of cultivators, and when better known, will certainly be regarded with favor. Lambert says the timber is very valuable and adapted to a variety of uses. 4. P, COntorta, Douglas. — TWISTED-BRANCHED PINE. — Leaves, 2 inches long, from a short, dark, imbricated sheath, numerous, rigid, sharply mucronate. Cones, from 2 to 2^- inches long, smooth, ovate, clustered ; scales fur- nished with a caducous mucro. Branches, twisted, slen- der, spreading, and thickly covered with leaves. Buds, very resinous, roundish, obtusely pointed, and brown color. A rare tree in cultivation, having been quite recently introduced into European collections. Loudon says : " This pine was fo'und by Douglas in North-west America, on swampy ground near the sea-coast ; and, abundantly, near Cape Disappointment, and Cape Lookout. Dried specimens, with cones, were sent home in 1825-6-7." Pinus contorta, says Dr. Parry, '* is quite abundant on the crest and slopes of dry sub-alpine ridges, forming the principal part of the forest there, and extending to near the snow line ; a symmetrical tree of rapid growth, 30 or 40 feet high, with slim and tapering trunk a foot in diam- eter, a smoothish, grayish-brown bark, detached in thin scales, and tough but coarse wood, which is liable to warp, and rarely cut into boards." Other writers have described this species as attaining 4* 82 THE BOOK OF EVERGREENS. the height of from 10 to 20 or 30 feet, and state that it is o " found along the north-west coast of North America, where it forms a low, straggling bush, not unlike P. Uanksiana, or poor specimens of P. mops. In fact, Hooker consider- ed it as a mere variety of the latter; but other botanists, among whom was the discoverer Douglas, claim it as a true species. We feel not the least hesitancy in placing it as such, since more modern research has given it a just right to the distinction. Being an inhabitant of the most northern confines of ar- borescent vegetation, it will certainly prove hardy with us, and for peculiar situations, as well as for producing particular effects in landscape gardening, it may prove of use ; but as an ornamental tree, we fear its straggling and crooked branches will prove objectionable. 5t P* glabra9 Wctlter. — SPRUCE PISTE. — Branches and branchlets, smooth, whitish. Cones, generally solitary, somewhat cylindrical, spines nearly obsolete. In close, rich soil, near Black Oak, South Carolina. (Ravenel.) — A tree from 40 to 60 feet high, with smoothish bark and soft white wood, branching from near the ground. Leaves, from 3 to 4 inches long. Cones, about 2 inches long. " Wings of the seed lighter colored, more tapering, longer and less gibbous than those of P. mitis" This species of Walter, long overlooked, but lately revived by Mr. Rav- enel, is, if I mistake not, not uncommon in the low hum- mocks of this State (Florida), and is distinguished here, as in South Carolina, as the Spruce Pine. (Chapman). We introduce this species to the notice of our readers on account of its being a native, believing that our own trees should receive our especial attention, if in the least deserving. This species may be rather tender for a north- ern latitude, but we confess our ignorance on the subject, never having 'had an opportunity of examining or testing it. The above description is taken from the reliable work by Dr. Chapman, entitled "Flora of the Southern States," on the authority of which we have placed it here. THE PINE SUB-FAMILY. 83 A number of the Southern Conifers having been suc- cessfully grown in the Middle States, such as the Torreya taxifolia, Taxodium distichum, Plnus australis, etc., we can perceive no cause why this fine tree should not prove equally available. 6. P, Halepensis, Mill. — ALEPPO PIXE. — Syn. P. hierosolymitana, Du Samel. — Leaves, 2 or 3 inches long, seldom *in threes, slender, dark green in color. Cones, from 2^- to 3 inches in length, invariably turned down- wards, long peduncled, and producing medium-sized seeds, with long wings. Cotyledons, 7. Branches, long and naked. Buds, from -J to £ inch long, roundish, imbricated, and destitute of resin. This species, notwithstanding its resemblance to the P. Jlrutia, is vastly inferior to it, especially in this latitude. It is found in several of the countries bordering on the Mediterranean, especially in the south, of Spain, France, Greece, etc. It forms a small tree, scarcely ever exceed- ing 25 feet in height. Our experience with it has not been so satisfactory as we could have wished ; some seasons standing without protection, and in others being entirely killed. Its healthfulness depends much upon the nature of the soil, as it is extremely impatient of a cold, damp soil, and on such almost absolutely refuses to thrive ; whilst on a more congenial, light, well-drained border, which is also somewhat protected from the cold north winds, it may succeed. The specimen in the Evans' Arboretum, at Radnor, Delaware Co., Pa., appears to be pretty well acclimated, and although it is in a very sheltered situation, has the ap- pearance of being somewhat out of its latitude. London says : " P. Halepensis is the most tender of European Pines, not even excepting P. Pinea;" and afterward adds : " In Britain, P. Halepensis can only be considered as ornamental, and, when planted singly on a lawn, it 84 THE BOOK OF EVERGREENS. forms one of the handsomest species of the genus. Ac- cording to Bosc, it is the most elegant of European Pines." The foliage, we think, is the only redeeming feature of the tree, being of a beautiful, light green color ; but un- fortunately, this is shed so copiously as to impart a naked appearance, which has anything but an ornamental effect. A variety, P, Halepensis Pityusa, Stevens, which has been honored by eight or ten synonyms, is also cultivated in Europe, and is described as being very distinct from the type in the size of the leaves and the cones, as well as in forming a much larger sized tree. This variety has been frequently sent out by foreign nurserymen as P. maritima, a name that is apparently only used when a plant is unknown, or as a convenient appellation for the Pine genus at large, for any, and every- thing that dishonest dealers wish to dispose of, for a reason- able compensation. We have seen so many distinct plants sent out under tins name, all of which belonged to old, well-defined species, that P. maritima has become, to us, a synonym of doubt and uncertainty. There is no species by that name in the Conifer®. Yar. minor, London, and var. genuensis, London, are placed as synonyms of the species by Gordon ; and the var. maritima, London, or P. maritima, Lambert, is con- sidered as synonymous with the var. Pityusa, by the same author. 7. P. inops, Alton. — JERSEY OR SCRUB PINE. — Leaves, 2 to 3 inches long, short, rigid, seldom in threes, with a short sheath. Cones, solitary, oblong-ovoid, 2 or 3 inches in length, frequently curved; peduncle, short. Scales, armed with a straight, rigid spine. Branches, spreading nnd very flexible", with a rough, dark bark. Seeds, small, and winged. This common native Pine is found very abundantly in many of the interior States of this country, and especially \ THE PINE SUB-FAMILY. 85 where the soil is of a poor, sandy character ; in such situa- tions it grows from 15 to 30 feet high. In the barren sec- tions of New Jersey, particularly, this species covers large tracts of waste lands, which are known as the Pine barrens. Some of the specimens even in these localities are quite handsome, being remarkable for the pale yellowish twigs and leaves, and in many instances forming fine sized trees of regular conical shape, although the large majority of them are but small, stunted shrubs, and far from orna- mental. The appearance of this tree is peculiar and striking ; the straggling branches are covered with dark, rough bark ; the young shoots, beautifully tinged with violet ; and the whole plant is almost covered with exuding resin, which emits a pleasant fragrance or balsamic odor. In some parts of Kentucky tar is obtained from this tree, but for other purposes the wood is of little value. We cannot recommend it for ornamental planting, but in a large collection, one or two well-grown specimens would not be amiss, it being greatly improved by generous cultivation. A noted European writer has said that, " as in Europe, almost all the American Pines can only be con- sidered in the light of ornamental trees, this species, as such, well deserves a place in collections, from the singu- larity of its form, its delightful fragrance, and its hardi- ness." We are afraid our cultivators are not sufficiently interested in arboriculture, however, to appreciate these eulogistic remarks. 8, P, Laricio, Poiret. — CORSICA^ PIXE. — Leaves, from 4 to 6 inches long, slender, very wavy, with short sheaths. Cones, 2 to 3 inches or more in length, conical- oblong, recurved at the apex, tawny brown in color. Scales, with a scarcely perceptible prickle. Branches, in regular whorls, spreading, and very resinous. Buds, £ to SO THE BOOK OF EVERGREENS. 1 inch long, ovate, ending in a long narrow point. Seeds, rather large. Cotyledons, @ to 8. A fine, hardy tree, from the south of Europe, in the Island of Corsica, etc. Prof. Tenore mentions vast forests composed of this species on the Mountains of Sila, in Calabria. It mostly attains a height varying with the situation, from 80 to 100 feet ; and London states : " In the Island of Corsica, it is said there are trees of this spe- cies, from 140 to 150 feet in height." On Mt. Etna, it forms forests at an elevation from 4000 to 6000 feet. This species, according to Loudon, is a more rapid grower than even P. sylvestris,'b\it it is quite a short lived tree, the duration being in Corsica but from 70 to 80 years. From the many instances of its rapid growth given in London's Arboretum, we make the following extracts: — 5 O " The rate of growth in the climate of London is from 2 feet to 3 feet in a year. A tree in the Horticultural Soci- ety's Garden, having been 12 years planted, was, in 1834, 20 feet high, and is now, 1837, 25 feet high. A shoot of the year 1829, with part of 1828, cut from a tree 5 years old, on M. Yilmorin's estate, at Barras, and sent to Mr. Lawson's Museum, measured 3 feet in length and 3|- inch- es in circumference at the thickest end. In Loddiges' Arboretum, this species and its varieties had attained in 1837 about from 20 to 30 feet, whilst the P. sylvestris and its varieties had not exceeded 12 feet. In France, according to Thouin, P. X/aricio grows two-thirds faster than the Scotch Pine, placed in a similar soil and situation." For lawn-planting, the Corsican Pine is one of the most beautiful and available trees that we have, and is almost invariably an attractive object in a collection. As it is a native of warm climates, many persons suppose it will prove too tender for this section, but so far as we have been -able to ascertain, it has given entire satisfaction. The long, wavy leaves are of a bright green color, and the perfect shape of the tree has always produced a favor- THE PINE SUB-FAMILY. 87 able impression with us, and we wish it were more extensively known. The wood is quite valuable for lum- ber, being long-grained, white, easily worked, and accord- ing to some authorities very durable. Var, caramaiiica* .London. — Syn. P. caramanica, JBosc / P. caramaniensis, Son Jcird, etc. — According to Loudon, this variety u has a much rounder and more bushy head, with straight or nearly straight leaves, slender branches, reddish-colored bark, which is wholly or in part covered with white resin. The scales of the cones, which are larger than those of P. Larwlo Oorsicana^ are tipped with a harder and more horny point." Our own specimen, although quite small, is nevertheless distinct from the species. Var, CalaMca, Delamarre. — From the mountains of Sila, in Calabria, where it forms a fine-sized tree, with the branches densely clothed with leaves that are longer than those of the common form. It is quite hardy here, and will doubtless prove desirable and distinct. Var, COntorta, mentioned in Gordon's Pinetum, we have not seen. It is described by that author as " having its lateral branches contorted or twisted round in different directions." Var, pyglihTa, Rauch. — Is a very curious little dwarf variety, that is quite pretty for ornamental shrubbery. The branches almost trail along the ground, and beai short, rigid, curled leaves. There are other varieties of this species that vary so lit- tle from the original as to be unworthy of perpetuation, excepting in the collection of the enthusiast ; and even in these, should the labels become accidentally lost, the owner would be at loss to identify the varieties, and probably soon be convinced that he had simply duplicates of the true species. 88 THE BOOK OP EVEEGEEEXS. 9. P. mitis, Michaux. — SHOET-LEAVED YELLOW PINE. — Syn. P. variabilis, Pursh. — Leaves, from 3 to 5 inches long, with long sheaths, slender, channelled, and dark green color. Cones, oval or conical-oblong, nearly 2 inch- es in length, usually solitary, light brown color, Avith a short incurved spine on each scale; peduncle, short and stout. Seeds, quite small, with reddish wings. This valuable native tree is found in various sections of our country from 'New England to the Gulf of Mexico. In New Jersey, especially, it is quite common and may be frequently seen in large numbers with P. inops. In the generality of cases it prefers a poor, sandy soil, although occasionally flourishing in fertile places. On a mod- erately rich, well-drained surface, it forms a beautiful spec- imen, not unlike in appearance to many of the rare Mexi- can species; and in f-ict, with careful cultivation, and sufficient space to develop its peculiar natural beauty, the P. mitis will compare very favorably with the majority of these much-extolled and tender strangers. It varies considerably in height with the quality of the soil and in the situation where it is found ; but the medium size is probably about 50 feet. According to Meehan's Hand-book of Ornamental Trees, the Bartram specimen is 90 feet high, and four feet eight inches in circumference ; it is growing on a dry, gravelly soil, with a rocky bottom. The timber furnished by this species is very valuable, although inferior in quality to the Long-leaved Yellow Pine, (P. australis,) but readily commands a good price not only in our own markets, but in those of European ports, and in consequence has been quite largely exported. The wood is fine-grained, and when devoid of the sap or outer portion, is remarkably durable. The timber is especially valuable in ship building, being excellent for mnsts, spars, etc., and is consequently in great demand for those purposes. The resinous properties of the species are not of sufficient interest to make it valuable on that THE PINE SUB-FAMILY. 89 account, although yielding a fair proportion of tar and turpentine. In a comparison of the opinions of Michaux and Lam- bert, in regard to the value of the products of this Pine, Loudon gives the following extracts. " Though this spe- cies," Michaux observes, " yields turpentine and tar, their extraction demands too much labor, as this Pine is always mingled in the forest with other trees." Lambert, on the contrary, asserts that "the wood has a sponginess and lightness which deprives it of durability, and renders it useless in building, or, indeed, for any purposes of a simi- lar kind ; but it is tolerably full of resin, so that the Americans employ it for its tar and pitch." In an ornamental point of view, it compares very favor- ably with the majority of our cultivated foreign species. The handsome, conical-shaped head has given it the name of Spruce Pine; in some sections such may possibly be the P. glabra, of Walter. The peculiar richness in the coloring of the leaves, softly merging from a bright blu- ish green to the darkest hue, in the alternate changes of light and shade, is really charming. The leaves are very fine, slender, and flexible, and im- part a peculiar beauty to the tree, which is not met with in any other Pine that is a native of the Northern or Mid- dle States, excepting, perhaps, a chance specimen of P. rigida. On this account, a recent writer in recommend- ing h for cultivation, very appropriately compared it to the Austrian Pine, and says : " so far from being naturally a scraggy tree, it thickens-in more naturally than any Pine I know." A peculiarity in this species is, that when growing very luxuriantly in rather rich soils, the leaves will often be found three in a sheath, thus giving rise to the synonym of Pursh, P. variaMUs, as well as the P. intermedia, of Fischer, being deemed intermediate, or as a connecting link between the Binae and Ternatse sections. Loudon also 90 THE BOOK OF EVERGREENS. appears to have been misinformed in regard to the true species, or, as is very probable, has overlooked this dispo- sition of the leaves to sport into threes ; for he says in his description of this species : — " The P. variabilis of Lambert's Pinus, is unquestion- ably a totally different plant from the P. mitis, of Mich- aux ; being without the violet-colored glaucous bloom on the young shoots, having rigid leaves, generally in threes, and a cone with very strong prickles like that of P. Twda, to which species we have referred it." We have occasionally seen specimens that were entirely devoid of the violet color on the young shoots as above referred to, and in fact, very different from the species in many minor points, but yet grown from the same tree as others that had every peculi- arity of P. mitis fully developed. P. mitis appears more nearly allied to P. inops than any other, and young plants of each are extremely difficult to be distinguished. 10. P. Mugho, JBauhin. — MUGHO PIXE. — Syn. P. Mughus, London. — P. sylvestris Mugho, Bauhin. — Leaves, nearly 2 inches long, rigid, twisted, dark green color. Cones, conical, shorter than the leaves, sessile, very resinous, generally in pairs, with the scales ending in a pyramidal, quadrangular recurved spine. Sterile aments, almost sessile, and the anthers surmounted by an oval, membranaceous crest. Branches, very numerous and as- cending, thickly covered with leaves and a light colored bark. This dwarfish tree, or shrub, has been the subject of many mistakes, not only in nomenclature, but by venders distributing all kinds of stunted Pines under this name. But the great majority of mistakes have occurred by con- founding the true species with its var. rostrata, under the common name or synonym of P. montana, and also with the P. pumilio / they are so very similar in general ap- pearance, that in the absence of the cones, it is a difficult task to distinguish them. We follow Gordon in his clas- sification of the varieties. THE PINE SUB-FAMILY. 91 The P. Mugho forms a small tree about 25 feet in height, but is occasionally only a large shrub. " M. Vil- lars observes that, when it grows on the summits of moun- tains, it is a mere bush ; but that, as it descends to the plains, it becomes a tree." (Loudon.) It is from the mountains of Central Europe, and is found growing on the Pyrenees and Alps. Although, of too small a size to produce valuable timber, the wood is never- theless very close-grained and durable, and of a bright red color. In ornamental plantations, we have seen this Pine used to excellent advantage, particularly where a mass of per- sistent foliage was desired. The dark green color of the leaves, in conjunction with the great density of the whole plant, admirably adapts it to this purpose. It is quite as hardy as our own native species, enduring the greatest de- gree of cold, and the most severe winds that visit our latitude, with perfect impunity. Gordon arranges the hitherto numerous varieties of this species, as follows : Var. rostrata, Antoine. — Syn. P. montana, Bau- mann ; P. sylvestris uncinata, Wlddrington. — This vari- ety is said to be found on the upper zone, or line, of the forest vegetation of the Pyrenees. Capt. "Widdrington states that "this Pine is extremely valuable from its hard- iness, as well as for the resinous quality and great dura- bility of its timber." He also remarks : " As an orna- mental tree it will be highly desirable, from the intensely dark green of its foliage, as well as the close and solid mass it forms ; and the habit of the tree, where left at liberty, to throw out massive arms trailing on the ground, a quality so unusual in its class." It forms a small tree about thirty feet high, and produc- es cones, with the scales greatly elevated, hooked at the points, and larger than those of the species. Var. rotundata, Link. — P. montana, Wahlenberg.— 92 THE BOOK OF EVERGREENS. Has a more upright growth than the species, with round- ish cones, and a straight, distinct leading stem. It is from the Tyrol, where it forms a small tree. Var. llliginosa, Wimmer. — Syn. P. Fischeri, Booth. — " This is the Austrian form of P. Muylio, but very much more robust in stature, forming a handsome pyramidal small tree." Var, liana, London. — KNEE PINE. — London, in his "Arboretum," places this as a variety of P.purnilio, and describes it as follows: "The Knee Pine of the Styrian Alps never grows above 3 feet high. A plant has been in the Trinity College Botanic Garden, Dublin, since 1817, and, in twenty years, it has not attained a greater height than an ordinary-sized man's knee." 11, P, muricata, D. Don. — BISHOP'S PINE. — Syn. P. Murrayana, JBalfour. — P. Edgariana, ffartweg. — Leaves, from 3 to 4 inches long, from a medium sized sheath, rigid, stout, bright green color. Cones, 3 inches long, ovate, in clusters, crowded, with thick, wedge-shaped scales, that are mucronated, with an elevated umbilicus. Branches, irregularly spreading, with small acute buds. Seeds, small, dark brown. This curious Pine is a native of Upper California, and according to ISTuttall, was discovered by Dr. Coulter, at San Luis Obispo, in latitude 35°, and at an elevation of 3000 feet above the level of the sea, distant about ten miles. The height is generally about 30 or 40 feet, and it grows very straight, with a somewhat stunted appearance. The strangest peculiarity about this species is in the " squarrose spreading of the basilar scales, which present long and sharp points in all directions." We are not aware of this tree having been tested in this country, although it has proven hardy in England ; but we cannot see anything to prevent it from succeeding as satisfactorily with us, as many Conifers from the same locality flourish here with perfect hardiness. It is true, THE PINE SUB-FAMILY. 93 the P. insignis, a native of the same section, aud often found growing in close proximity to this species, will not succeed here under the most careful treatment ; and the Bishop's Pine may unfortunately be of the same temper- ament, although we sincerely hope to the contrary. Hartweg found it growing on the western declivity of the mountains near Monterey, and within two miles of the sea-shore ; and afterward at a considerable distance to the south of the same place, on the ascent to the Mission of La Purissirna, where the trees were of rather small size. Jeffrey met with it on the Siskiyou Mountains, at an elevation of 7500 feet, near the summit of the mountain, growing in damp soil. Of the value of the wood, we have no account. 12, P, Pallasiana, Lambert. — PALLAS' PINE, TAR- TARIAN PINE, TATJRTAN PINE. — Syn. P. Laricio Pallasi- ana, London. — P. Taurica, Hort. — P. maritima, Pallas, etc. — Leaves, from 4 to 8 inches in length, from a short sheath, erect, rigid, acute, channelled, light shining green color. Cones, 4 to 5 inches long, oblong, often curved, sessile, solitary or in small clusters ; the scales resembling those of P. Laricio, but larger and terminating in a small prickle. Seeds, medium size, obovate ; with broad, slen- der, membranaceous wings. " P. Pallasiana is confined to the central regions of the Crimea, forming considerable forests on the western decliv- ity of the chain of lofty mountains which extends along the coast of the Black Sea. It was first introduced into England by Messrs. Lee & Kennedy, of the Hammersmith Nursery, who raised a number of plants from seeds sent to them by Prof. Pallas, from the Crimea, about 1790, and it was sold by them as P. Tartar ica" (Loudon.) Plants raised from the above seeds were set out at Boyton, and are now from 60 to 70 feet in height. Oth- ers planted at White Knights by the Duke of Marlbor- ough, are from 50 to 60 feet in height. 94 THE BOOK OF EVERGREENS. " As an ornamental tree," says London, " P. Pallasiana deserves a place in every collection ; " and Lambert ob- serves : " Of all pines, this is the best adapted for thin chalky soils, and maritime situations." We have had it in cultivation for several years, and, for its distinct habit of growth and great hardiness, have been induced to rec- ommend it; and should the adult trees prove as satisfac- tory as the young plants promise, it will probably be one of our finest ornamental pines." Loudon, who, evidently, has never seen large plants, labors under a mistake in confounding it with the P. Laricio ; the two are now considered botanically dis- tinct, and are at least quite unlike in general appearance. In Sargent's edition of Downing's Landscape Gardening, (the editor of which has probably a wrong plant), it is described as " not very distinctive, as it resembles exceed- ingly our White Pine." With us, it has the same habit of growth that marks the Austrian Pine ; and, in fact, so nearly approaches that species in many leading character- istics, as to induce some acute arboriculturists to believe it would prove to be a variety of P. Austriaca. "According to Prof. Pallas, the wood is very knotty and resinous, and very durable, but difficult to form into good planks on account of the number of its knobs." — (London.} 13. P.

Cones, from. 4 to 6 inches long, conical, ses- sile, clustered, with broad, ash-colored, pyramidal scales, that terminate in a small sharp point. Branches, in whorls, stout, with rather long, imbricated, pointed woolly buds, that are devoid of resin. Seeds, oblong, medium, with large Avings. Cotyledons, 7 or 8. This beautiful species, with all possible care, is exceed- THE PINE SUB-FAMILY. 95 ingly unsatisfactory, and cannot be depended upon in the Northern and Middle States. It is a native of the Medi- terranean coast, and is found in almost every country bordering on that sea, as well as in the north of Africa, and in portions of Asia, although some writers contend it is an introduced plant in these latter places. The Cluster Pine is generally found growing from fifty to seventy-five feet in height, and forms a remarkably handsome shaped tree. On the sandy plains in the Apen- nine range of mountains, this tree flourishes with unusual vigor, and in many sections of that region of country, tracts of sandy, waste places have been planted with it, that now yield annually a large quantity of wood for fuel, as well as an inferior article of lumber. On calcareous soils, however, it has been asserted that this species will not thrive, an idea it would be well to bear in mind before testing its availability. It is a valuable auxiliary to those residing near the sea-shore where many plants refuse to thrive, as the salt breezes in those localities do not aifect it in the least. The vast extent of country in which this pine has been detected, as well as the number of varieties and different forms of growth it assumes, have given rise to a multipli- city of synonyms, which many of our best authorities have added to ; but justice to their discrimination demands that the fact of so great a diversity of names, by such observing and intelligent botanists, should be attributed to the species having manifestly different habits and pecu- i liarities in the various countries where it has been found. Var, Hamilton!!, Tenore. — LORD ABERDEEN'S PINE. — Syn. var. escarenus, Loudon. — P. escarena, Risso, etc. — According to Loudon, " The leaves are of a paler green than those of the species, but they are equally long and strong. The cones are shorter, and more ovate." This is the most distinct and handsome variety of P. Pinaster 06 THE BOOK OF EVERGREENS. that we have seen ; it was first introduced into Britain by the Earl of Aberdeen, in 1825." Var. Lemoniana, London. — The same authority says of this variety that it " is also a very distinct variety, but quite the opposite of the last, being a stunted, bulky plant, with zigzag, close, and twiggy branches, and stand- ing apparently in the same relation to P. Pinaster that P. pumilio does to P. sylvestris" He also adds : " There is nothing dwarfish or diseased in its appearance, nor does it exhibit any peculiarities of constitution to which other pines are not subject." Var. minor, London. — Syn. P. maritima minor, Du Samel. — Is, according to London, a " variety which is chiefly distinguished by the somewhat smaller size of its cones, being from 3J inches to 4 inches long, and If inches broad, and is said by Bosc to be produced by a colder climate, and to abound on the west coast of France, espe- cially on the barren sands in the neighborhood of Mans, and to be hardier than the species." Var. foliis Yariegatis, Loudon.-^-Syn. var. variegata, G-ordon. — " Was discovered by Mr. Cree, the founder of the Addlestone Nursery, towards the end of the last cen- tuiy." The young shoots and foliage are rather prettily striped with straw color. A number of other varieties are also noticed by Loudon ; but later authors, among whom is Gordon, class them as synonyms of the species; the above may not prove more hardy than the common form, but are worthy of a trial by all interested in this genus. 14, P, Pinea, Linnceus. — STONE PINE. — Leaves, from 5 to 7 or 8 inches long, with short, lacerated sheaths ; stout, of a deep green color. Cones, 5 or 6 inches in length, ovate, obtuse, glossy, light brown in color ; with large, woody scales, terminating in a recurved, deciduous, blunt prickle. Seeds, large (f inch long), nut-like, edible, 5 THE PINE SUB-FAMILY. 97 with a broad wing, one inch long. Cotyledons, 9 to 11. (Crest of the anthers jagged. Smith.) We only mention this beautiful species for the purpose of inducing those favored with a milder climate than our own to give it a fair trial. It will not grow here with the least hope of success, but in its native habitat, the countries of Southern Europe, it forms a splendid tree, and adds vastly 'to the effect in picturesque landscapes. In England this pine rarely exceeds 20 or 30 feet in height, but when cultivated in many sections along the Mediterranean, its height varies from 50 to 60 feet. The specimen in the Evans' Arboretum is about 6 feet high, and has managed to survive several winters without arti- ficial protection, but is nevertheless devoid of beauty, owing to the sickly appearance of the foliage. In noticing the nutritious properties of its seeds, Loudon gives the following instances : " The kernel of the fruit has a taste which approaches to that of the hazel-nut, and, in France and Italy, is much esteemed for the dessert. Sir George Staunton mentions that the kernels of the Stone Pine are also much relished by the Chinese. In Italy they are put into several kinds of ragouts, and they prove ex- cellent in sugar plums instead of almonds. In Provence, they are extensively consumed along with Corinth raisins, the dried currants of the shops. The kernels require to be kept in the cone till they are about to be used, because they become speedily rancid when taken out and exposed to the air. In the cone they will preserve their vitality, their freshness, and their taste, 5 or 6 years." Loudon and Gordon mention Var. fragilis, Du Harriet, with a thin-shelled seed ; and Var. Cretica, London^ with very large cones and slender leaves, as somewhat distinct. The latter forms a much larger tree than the species. There are a number of unimportant synonyms attached to this pine by various authors. 5 98 THE BOOK OF EVERGREENS. 15, P. pumilio, Hwnke. — DWARF PINE, MOUNTAIN PINE. — Syn.

Cones, from 1-J to 2 inches long, reddish, or dark purplish-brown when young, and dull brown when mature ; when young, erect, when mature, pointing outwards. Buds, ovate, blunt, resinous. Scales and seeds resembling those of P. sylvestris, but smaller. Cotyledons, 5 to 7. (London's Arboretum.) A dwarf species from the Alps of Middle Europe, from an elevation of 4000 to 7500 feet. It prefers a damp soil ; when on dry, sandy bottoms, it never produces its remark- able density of growth, or dark, healthy green color. It will occasionally attain to the height of twenty feet, but in the generality of cases is but a small creeping shrub, with horizontal, trailing, and recurved branches, and form- ing a dense mass of wood and foliage. It is chiefly found above the regions of the taller trees, and in such instances is invariably small. Some writers speak rather disparagingly of its merits as an evergreen shrub, and indeed, in this country it has never,' until re- cently, received that encouragement which it justly de- serves ; but thanks to an increasing taste for horticultural pursuits, it has lately become quite popular. With generous treatment to allow of a perfect develop- ment, it has always been an especial favorite with us, and one which we would not readily dispense with. It is very hardy, withstanding our coldest winters without protection of any kind, and grows rapidly. It may be readily propagated from seeds, which are generally imported and sold by our seedsmen at a comparatively low price. The wood is very resinous, and is said to produce the Hungarian Balsam. 16.

Cotyledons, 6 This species, in favorable soils, attains the height of from 40 to 50 feet, and is confined to a somewhat limited habit- at. It is found on the "mountains, rarely west of the Blue Ridge, Georgia to North Carolina, and northward." (Chapman.) In regard to this limitation Michaux, in describing it, 100 THE BOOK OF EVEKGEEENS. remarks as follows : " Of all the forest trees of America, this species alone is restricted to such narrow limits, and it will probably be among the first to become extinct, as the mountains which produce it are easy of access, are favored with a salubrious air and a fertile soil, and are rap- idly peopling ; besides which their forests are frequently ravaged by fire." But Nuttall, in his description, says : "The quantity of this species on the Table Mountain, and on a wide stretch of high mountains for many miles north and south of this locality, is very great, and no apprehen- sions need be entertained, nor is there the most distant probability, of its ever "being extirpated by the puny hand of man." Such difference of opinion between these au- thorities is somewhat remarkable ; but in the case of the lat- ter, his superior advantages for examining the trees in their native locality entitle his description to the greater credit. Later investigations have proven that it extends over quite a large tract, forming a dense growth of a peculiar light green color, which is observable for a great distance. JSTuttall says : " On the vast precipices, slopes, impend- ing rocks and chasms of the Linville, a branch of the Ca- tawba, it darkens the whole horizon and presents an im- posing mass of intense and monotonous verdure. It gen- erally occupies the summits of the highest rocky ridges, and sweeps over the most dangerous and inaccessible de- clivities to the margin of precipices, some of which, over- hanging the cove of Linville, are at least 1000 feet perpendicular." The timber is not particularly prized, and the resin not of sufficient value for manufacturing purposes. The out- line and general appearance of the tree bears quite a strong resemblance to the Scotch Pine, excepting in the color of the leaves. A peculiar feature of this pine is the great length of time which the cones remain on the branches, and being generally in whorls, they create an odd effect. Loudon in- THE PINE SUB-FAMILY. 101 forms us : " At Dropmore there are cones adhering to the trunk and to large branches of more than 20 years growth, giving the tree a very singular appearance, and rendering its trunk easily distinguishable, even at a distance, from those of all others of the Pine tribe." He also says : " In Britain, P. pungens can only be considered as an or- namental tree ; but, from the singularity of its cones, it well deserves a place in every pinetum." We desire to add that solitary specimens of this pine are occasionally very handsome, and when covered with their curious masses of cones of different ages, the effect is very striking. Moreover, it is a native tree which has been sadly neglect- ed heretofore, and we desire to encourage its dissemination. 17. P. Pyrenaica, La Peyrouse. — PYKENEAST Pro:. — Syn. P. Laricio Pyrenaica, London. — P. Hispanica, Cook. — P. penicellus, La Peyrouse, with numerous others. — Leaves, from 5 to 7 inches long, from a long sheath, stiff, crowded in tufts at the extremities of the shoots, pale green color. Cones, &J inches long, conical-oblong, generally solitary, short peduncled, smooth, light • yellow color, and standing horizontally to the branches. Scales, mostly spineless, small. Seeds, small, with a narrow wing. This beautiful hardy pine, known by some twelve or fourteen synonyms, forms a valuable addition to our col- lections. It comes from the forests of France and Spain, often oc- cupying the highest ranges of their mountains; and not- withstanding the great difference in temperature, it has proven entirely reliable in this country, and may eventu- ally be one of our most valuable ornamental trees. It grows from 60 to 80 feet high, is of a regular conical form, quite compact in shape, and distinct in appearance. London's synonym of this plant, P. Laricio Pyrenaica> is a misnomer, the true plant being specifically distinct from P. Laricio, and also very unlike P. Strobus^ as unfor- tunately described by another author. The species under 102 THE BOOK OF EVERGREENS. notice has more the appearance of P. Austriaca, with light colored foliage, and like it, will undoubtedly prove popular. We lately heard a discriminating botanist as- sert that the Pyrenean Pine formed one of the finest speci- mens of the genus, and as such he intended to recommend it. Loudon states that " Capt. Cook, who introduced this species in 1834, found it occupying the highest range of the extensive forests of the Sierra de Segura, in the south of Spain, where it overtops P. Salepensis, and in a corre- sponding situation in the vast forest region of the Sierra de Cuen9a, on the river Gabriel, in Upper Aragon, where it forms extensive forests; but La Peyrouse appears to have only found it in the Pyrenees." Capt. Cook, M. Peyrouse, and others, have described this species under different names ; hence the great number of synonyms and consequent confusion in regard to its proper position in a scientific classification. Capt. Cook, in his description, says " it is quite hardy, of quick growth, and will, from its noble appearance, the beauty of its form, and the clear, transparent color of both the bark and foliage, be a vast acquisition to our park scen- ery. The timber is white and dry, being nearly without turpentine, but the cones exude a most delicious balsamic odor. It is one of the species described in the book of Arab agriculture, written by a Moor of Seville, in 1200, and translated by Banqueri." 18, P. resinosa, Alton. — RED PINE. — Syn. P. rubra, Michaux. — P. Canadensis bifolia, Du Jfamel. — Leaves, 5 to 6 inches in length, semicylindrical, from long sheaths, rigid, straight, elongated, dark green color. Cones, 2 inches long, ovoid-conical, usually in clusters, short pedun- cled, writh pointless scales. Branches, with smoothish, red bark, and long, acute, resinous, buds. This tree varies in size, being from 50 to 80 feet high, and is found from Pennsylvania northward through Canada, Nova, Scotia, etc. The specific name is derived from the THE PINE SUB-FAMILY. 103 great quantity of resinous matter contained in every por- tion of the wood, although not so abundantly as in P. rigida. The common name is in allusion to the color of the bark, which is a beautiful bright red ; and so distinct is this peculiarity that Michaux, in describing the species in his North American Sylva, thought proper to change the name to P. nibra, but, however applicable this name may be, such innovations cannot be allowed. This is one of the trees sent to England by our first botanist, the inde- fatigable and enthusiastic Bartrani; although it was grown in Britain by Hugh, Duke of Northumberland, in 1756. According to Loudon, " about the end of the last cen- tury, Messrs. Loddiges raised nearly 100 plants of P. res* inosa, from seeds received from Bartram, of Philadelphia, and nearly the whole of these were planted by the then Marquis of Blandford, (the present Duke of Marlborough) at White Knights, where a number of them still exist." The Red Pine delights in a dry, sandy soil, and in such forms a distinctive and not inelegant tree. A somewhat remarkable feature connected with its growth consists in the leaves being borne in dense bunches on the ends of the branches. This unusual form is not confined entirely to this species, but is also observed in the P. australis, and probably a few others. The leaves are quite handsome, be- ing rather long arid of a rich, dark green color, which, contrasting with the reddish hue of the bark, produces a pleasing effect. Although this pine is not of sufficient utility for a specimen tree in small ornamental plantations, it must not be altogether neglected, as the striking peculi- arities mentioned above, combined with extreme hardiness, strong healthy growth, and adaptation to almost all soils suitable for Conifers, fully entitle it to a place in large collections. In the various uses to which the Pine family are applied, this species certainly deserves to rank high in our estima- 104 THE BOOK OF EVERGREENS. tion. The resin that abounds so plentifully throughout its structure, as well as the value of the timber, should be sufficient inducements for its cultivation. Michaux very justly advances the claims of this tree, and urges on Eu- ropean cultivators the advantages to be derived from such plantations. London says : " As an ornamental tree, this species is well deserving of cultivation." 19, P. sylvestris, Linnwus. — SCOTCH PINE. — (Numer- ous unimportant synonyms.) — Leaves, from \\ inches to 2^ inches long, with short, lacerated sheaths, twisted, rigid, light bluish-green. Cones, ovate-conical, from 2 to 3 inch- es long, grayish-brown color ; with a quadrangular, recurv- ed point. Seeds, small, with a long, reddish-colored wing. Crest of the anthers, very small. Cotyledons, 5 to 7. The Scotch Pine, often erroneously called Scotch Fir, is probably the most useful and numerous, as well as the most familiar, of all the European species. It is, in its na- tive country, what the White Pine is to us ; but in point of usefulness in all respects, it is far inferior to the latter. Some European writers, however, think differently, and as- sert the superior advantages of the Scotch Pine in the strongest terms. " The first modern record of the tree," says Loudon, " is by Matthiolus, who called it Pinus sylvestris montana, and sylvestris was afterwards adopted by Linnaeus." Al- though the common name would lead us to believe that it is either confined to Scotland, or is remarkably abund- ant in that country, some writers are in doubt of its being a native there, and are under the impression that it is an introduced plant; but throughout the central countries of Europe, this species forms vast forests, — in many sec- tions clothing the mountain sides with its dark green ver- dure. Especially in the colder regions, on the Pyrenees, Tyrolian, Swiss, and Yosgian mountains, it is seen in per- fection in the most elevated and bleakest situations imagin- able In those countries the Scotch Pine attains a height THE PIXE SUB-FAMILY. 105 of eighty feet and upwards, and is frequently four or five feet in diameter ; whilst as it approaches the extreme lim- Btl Fig1. 14.— PINUS SYLVESTRIS. its of arborescent vegetation, it dwindles down to a mere straggling shrub. 5* 106 THE BOOK OF EVERGREENS. It is one of the fastest growing species of the genus, and in regard to this particular, Loudon gives the follow- ing instances : " The seeds of the Scotch Pine come up in about four weeks after they are sown ; the growth is not above 3 inches or 4 inches the first year ; the second, if on a good soil, they will grow from 4 inches to 6 inches ; and the third year the plants begin to branch, and attain the height of from 14 inches to 2 feet, according to soil and situation. "In the fourth and fifth years, if not transplanted, or if they have been transplanted carefully in the second year, they begin to push strongly, making a leading shoot from 1 foot to 3 feet in length, according to soil and situation ; and they continue growing vigorously for half a century, according to circumstances. " In ten years, in the climate of London, plants will at- tain the height of 20 or 25 feet ; and in twenty years, from 40 to 50 feet. Evelyn mentions a Scotch Pine which grew 60 feet in height in little more than twenty years." " The largest Scotch Pine that was ever cut down in Scotland is supposed to be one which stood in the forest of Glenmore^ winch was called the Lady of the Glen, and of which there is a plank in the entrance hall of Gordon Castle, 6 feet 2 inches long, and 5 feet 5 inches broad." The rapidity of growth, great hardiness, and the facility with which it may be grown on almost all soils, has ren- dered this tree a great favorite with the arboriculturist ; although it greatly prefers a cool gravelly subsoil, that is well drained, and will then, in certain appropriate spots, often form a handsome tree, but always inclining more to the picturesque than the beautiful. Loudon, in his Arbo- retum, devotes several pages to this species, and dwells upon its use for ornamental purposes in quite a lengthy article ; but readers in this country must remember that in the large English parks and lawns, a great diversity of situation abounds, and many of the most picturesque are THE PINE SUB-FAMILY. 107 specially adapted to this tree, but on our smaller lawns it is frequently out of place. Its value for timber, although inferior to the White Pine and Southern Yellow Pine (P. australis), is never- theless of great importance, and in some sections of France and Belgium, large barren tracts have been plant- ed exclusively with this species, for the purpose of procur- ing lumber; in these calcareous soils, after the trees have been removed, the land has universally proved more fertile and productive than before, and yielded fair crops of grain. It is the Red and Yellow Deal of England, and is in use there for most purposes, both in naval and civil architecture. Its terebinthinate properties are also of great impor- tance, as vast quantities of tar are annually exported from Northern Europe to England, etc., where it forms four- fifths of the amount that is consumed. Var. horizontally Don. — This variety is from the Highlands of Scotland, with serrulated and broader leaves than the species, although not margined, and of a peculiar light glaucous color. The branches are remarkably hori- zontal and drooping. This is known by some as the Red- wooded Scotch Pine, Highland Pine, etc. Var. uncinata9 Don. — Is described by the author as having much lighter colored leaves than the foregoing, and very distinct, " insomuch that they appear of a truly light, glaucous hue, approaching to a silvery tint." They are also serrulated. The cones are different from those of the species, "being beset with blunt prickles, bent back- wards." Gordon classes this variety as a synonym of the species. Var, Hagucncnsis, London. — Is likewise placed as a synonym of the species by Gordon, but London extracts the following description from Lawson's Manual in regard to it. " The old trees are remarkably tall, straight, free 108 THE BOOK OF EVERGREENS. from branches, except near the summit, with remarkably smooth, reddish-colored bark. The leaves on the young plants are longer, waved and twisted, light green, slightly glaucous, and minutely serrulated; the young terminal buds are of a peculiar reddish color, and generally more or less covered with whitish resin." "The forests of Haguenau," M. Nebel informs us, " extended over up- wards of 30,000 acres, but the greater part of the pine trees were cut down during the war." Var. intermedia; London, — Is from Russia, with " slender young shoots depressed towards the stem, and leaves shorter and less glaucous than those of the species." Var. Altaica9 Ledebour. — A native of the Altaian Mountains, growing about fifty feet high, and introduced into England in 1836, by Dr. Ledebour. A dense, pyrami- dal tree, with shorter and more rigid leaves than the species. Var, tortuosa, Don. — Who describes it "as having the leaves shorter than P. s. vulgaris, and somewhat curled or twisted. He saw only 3 or 4 trees of it, and thinks it nearly approaches the P. Bariksiana of Lambert." Var, monophylla, Hodgins. — This variety has two leaves in a sheath, but united together throughout their length, thus imparting to the tree a very curious appear- ance. "When the points are taken between the finger and thumb, and the apparently single leaf twisted, it gen- erally separates into two, and sometimes into three leaves." Var, nan a, Hort. — " A very dwarf variety, not grow- ing more than one or two feet high, but spreading widely in a horizontal direction, and having very stunted branch- es and leaves." — (Gordon.) Var, variegata, Hort. — " This only differs from the or- dinary form in the mixture of its pale straw-colored, with the usual glaucous or bluish-green leaves, being produced on both old and young wood." — (Gordon.) Var, la I i folia, Gordon.-^ With several synonyms, is THE PINE SUB-FAMILY. 109 from the Caucasian Mountains, and, according to Gordon^ the leaves are much broader, more glaucous, and longer than any other variety of P. sylvestris. It is also very robust, and grows to a great size. Var, argentea, Stevens. — Is the Silvery Scotch Fir, with the cones and leaves a beautiful, silvery, glaucous color : a variety from the region of the Black Sea, where it attains a large size. We believe this has not yet been introduced into this country. There are other varieties mentioned by Loudon and others, that differ so little from the species as to be now unrecognized; such as var. Rigensis, var. Genevensis, etc. SECT. II.— TKRHTATJE.— THREE LEAVES IN A SHEATH. 20. P» aiistraliS; Michaux. — LONG-LEAVED OR SOUTH- ERN YELLOW PINE. — Syn. P. palustris, Linnaeus. — Leaves, 10 to 15 inches long ; from a long, lacerated, light colored sheath ; bright green color, and crowded in dense clusters at the ends of the branches. Cones, from 6 to 10 inches long, mostly cylindrical, of a beautiful brown color, with thick scales, armed with very small recurved prickles. Seeds, large, oval, with a long wing. With the single exception of the White Pine, (P. Stro- bus,) this species is perhaps the most valuable of the ge- nus, and along our southern sea-board States, particularly in Georgia and Florida, it is to be found in immense num- bers, covering large tracts of sandy, barren soil, to the almost total exclusion in many places of all other plants. The size of the trees varies greatly according to soil and situation. Along the roadsides and on sterile spots, they are poor, stunted plants but a few feet in height; but as the soil becomes more congenial they assume their proper proportions, averaging probably 75 110 THE BOOK OF EVERGREENS. feet in height, and single specimens frequently attain a much greater size. For ornamental pur- poses, this pine is well adapted to those sections where it will survive the inclemencies of our winters. The sudden changes, owing to the warm days and bright sun during winter, fol- lowed suddenly by the mercury sinking almost to zero, acting on the im- perfectly ripened wood, in many cases fatally in- jure the great majority of southern plants. With us it has stood out for several years, without any protection excepting a slight covering of pine branches during the win- ter, sufficient to afford it a partial shade. A beau- tiful specimen grew for several years on the grounds of the late Wm. Reid, at Elizabethtown, 1ST. J., and as it was planted in the centre of a group of evergreens, it thrived uninjured for a number of years. is.— PINUS AUSTRALIS. The late owner assured the author that in such sheltered situations it might be THE PINE SUB-FAMILY. Ill depended on in the Middle States. We have understood that it is not entirely hardy in the vicinity of London, and although known in Europe since the year 1730, it is not yet common in collections. The peculiar growth and remarkably beautiful foliage of this species certainly entitle it to the regard of all our cultivators, and with a small amount of care and attention for a few years, we feel confident it will fully repay the trouble expended upon it. The lumber of P. australis is as valuable as that of any other pine, but in some situations the wood is so charged with resin as to become in a measure almost valueless. In a comparison between the timber of the White Pine and Long-leaved Yellow Pine, that of the former is softer, more free from turpentine, and generally of a larger size ; whilst, on the other hand, the strong, durable planks and boards manufactured from the latter are unexcelled. In ship-building the lumber of this pine plays a very important part, and indeed is considered by some to be su- perior to oak for this purpose. The Carolina floor-boards, so universally preferred in all our large cities, are manu- factured from this species, and in many portions of the South the dwellings are constructed exclusively from this lumber, which also forms the fencing material that en- closes the fields. As fuel, it is poor, burning badly, with a dense, black smoke, and creating but little heat. The chief value of this species consists in its products, which, in value, are not equalled by those of any other of the family. North Carolina, for a number of years, derived a large revenue from the manufacture of the various products of this pine, as it not only supplied the demand of our own country for turpentine, rosin, tar, and pitch, but immense quantities of these were exported to European and other ports. The tar being extracted from the dead wood, no part of the tree in any stage is al- lowed to be wasted, and the accumulation of sap or resin, 112 THE BOOK OF EVERGREENS. as the wood advances towards decomposition, is greatly increased. The old Linnoean name of P. palustris, which was alto- gether inappropriate to the plant, was changed by Mich- aux to that which it now bears ; and, however we may deprecate the alteration and change of names, we have to confess that, in the present instance, it is justifiable. Var. excelsa, London. — Syn. P. palustris excelsa, Sooth. — Is unknown in this country, but, according to English and German writers, it is more hardy, much larg- er, and has longer leaves than the species. It is also re- ported to have been found on the north-west coast of America, which latter assertion is, however, very doubtful. 21, P. Fremontiana, Endlicher. — FREMONT'S PINE, NUT PINE. — Syn. P. monophyllus, Torrey. — Leaves, from 1£ to 3 inches long, with short sheaths, rigid, curved, sharply mucronate, and of a pale bluish-green color. Cones, 2£ inches long, light brown color and glossy, with thick, recurved scales, entirely destitute of spines. Seeds, quite large, wingless, and edible. A very distinct species from California, where it was discovered by Col. Fremont, and named in his honor by Prof. Endlicher. It was first called P. monophyllus^ by Dr. Torrey, who was under the impression that its leaves were solitary. Subsequent investigation, however, decided its true character and the present name was established. It was first found on the Sierra Nevada, extending along the sides and summits of the mountains for a dis- tance of 300 miles, and was afterwards detected by Jef- frey on Mt. Jefferson, in the Cascade range, at an elevation of 6,500 feet. Fremont mentions that the mercury fre- quently sank two degrees below zero at night in the above locality, and the snow was four feet in depth. We can- not, at the present time, assert its hardiness, as our specimen is yet quite small, but from the character of the climate of which it is a native we may safely recommend it for trial. THE PINE SUB-FAMILY. 113 It forms a small tree, probably not exceeding twenty feet in height, but well furnished with side branches and with a peculiar, glaucous, bluish-green foliage, which pro- duces a beautiful efiect. The seeds, like many others of our western species of pines, are edible and very nutri- tious, with shells so thin that they may readily be broken with the fingers. They constitute a large part of the sub- sistence of the Indians that inhabit those regions, and are gathered by them and stored away for winter use. Dr. Engelmann says of this plant in a recent article, that " it has single leaves, and not connate, as Endlicher would have it." This is one of those perplexing misun- derstandings that will occasionally happen among authors. Our own specimen was grown by the -late John Evans, a botanist of no ordinary talent, who procured the seed, if we mistake not, from its native locality. However, it re- tains all of the specific distinctions as described by End- licher, having three leaves in a sheath and being only very rarely monophyllous on the young shoots. This mono- phyllous state is not unfrequeiitly met with in other spe- cies, and its frequent occurrence in this particular one is doubtless the cause of the misunderstanding. The P. Fremontiana is one of the very slow growing species that require a number of years to arrive at maturi- ty, and consequently may not, on this account, prove so popular as some others. This edible, or nut-pine section, is of so much interest, that we make the following extract from Dr. Engelmann's article. " This very natural little group is characterized by the small, almost globose cones, the scales bearing large py- ramidal apophyses and large edible seeds,the wings of which remain attached to the scale, which, I suspect, is the casein all ' wingless ' seeds of pines ; in jR Pinea, however, the wing is very distinct, and detaches itself clearly from the scale, and at the same time also from the seed itself, which is likewise the case in the closely allied, though 5-leaved Cal- 114 THE BOOK OF EVERGREENS. ifornian P. Torreyana, Parry, where the wing, besides, is very thick and of a corky substance. The great vari- ability in the number of leaves in the nut-pines proves that sectional characters taken from them are without value." 22. P, Gerardiana, Wallich — GERARD'S PINE. — Syn. P. Neosa, G-ovan. — Leaves, from 3|- to 5 inches long ; from a short, deciduous, scaly sheath; rigid, crowded, glaucous-green color. Cones, 8 inches long, and 5 inches broad, ovate, resinous ; with broad, thick, corky, recurv- ed scales, terminating in a stout spine. Seeds, large, cylindrical, pointed, dark brown color, almost wingless, and edible. This beautiful tree was discovered by Capt. P. Gerard, in whose honor it was named by Dr. Wallich. It is a native of the Himalayas, and is found " on the northern side of the Snowy range of mountains in Kunawur, beyond the influence of the periodical rains, where it grows in very dry rocky ground. It is also found to the north of Cashmere, and on the Astor Mountains, in Little Tibet." Capt. Gerard mentions its highest limits on the inner Him- alayas to be from 10,000 to 12,000 feet. Its height is about 50 feet, and in congenial soil, with proper space to develop its peculiar beauty, it becomes a regular, dense, conical tree. The seeds, like those of the foregoing spe- cies, are large and nut-like, very abundant, and highly prized by the inhabitants. The Arabs and Persians have bestowed the name of " Sonoubar Sukkar," or the " Sweet Pine-nut," upon it, owing to this property. Although it is very distinct from the P. longifolia in many and very essential particulars, it was nevertheless frequently confounded with the latter species by early writers. The cones of the two resemble each other very closely, and on this account the confusion evidently arose in the first instance, as many of the first plants raised in England for P. G-erardiana have since proven to be P. longifolia. THE PINE SUB-FAMILY. 115 Its hardiness is yet uncertain, although we are favorably impressed with the experiments that have fallen under our notice. With us it proves successful, but we generally place a slight protection of evergreen boughs around the plant to shade it from the sun in winter. The color of its foliage is that of a beautiful glaucous green, and con- trasts agreeably with the darker hues in a group of pines. The large cones, with their peculiar thick, recurved scales and edible seeds, are also very interesting. This species is quite remarkable for the copiousness of its resin. 23. P. Jeffreyiij Sort. — JEFFREY'S PINE. — Leaves, 8 inches long, from long, lacerated, persistent sheaths ; acute, recurved, stout, dark green color. Cones, 8 inches long, ovate-conical, clustered, with broad, projecting scales, armed with very large, incurved spines ; seeds, quite large, and handsomely striped. This beautiful new species is from Northern California, where, according to Jeffrey, it inhabits poor, sandy soils, and forms a majestic tree 150 feet in height. It resembles the P. ponderosa somewhat in general ap- pearance, but has much more slender leaves. As regards the hardiness of this new candidate for popular favor, we are pleased to be able to place it amongst those that promise well. We have exposed it to the severity of sev- eral winters, all of which it came through safely. But it is proper to state that a more thorough trial is necessary before it can be considered as perfectly reliable. The branches of this pine are slender, very spreading, and of a pale, reddish-brown color ; the buds are small, and quite resinous. Like the most of our Californian spe- cies, it has large cones, which render it conspicuous, being furnished with large, pyramidal, hooked scales. 24, P, macrocarpa, LindUy. — COULTER'S PINE, GREAT-HOOKED PINE. — Syn. P. Coulteri, Don ; P. Sabin- iana Coulteri, London. — Leaves, 9 inches long, with long 116 THE BOOK OF EVERGREENS. sheaths, very Ibroad, rigid, incurved, acute, compressed, and light glaucous green color. Cones, "largest of the family," (ffuttall) / " 1 foot and more in length, 6 inches in diameter near the middle, and weighing about 4 Ibs.," (Lambert) / conical-oblong, solitary, shining chestnut- brown color ; with the large, indurated, wedge-shaped scales terminating in a long, recurved and compressed spine, 3 or 4 inches in length. Seeds, large, flat, edible, dark brown color, with long, stiff, light brown wings. This splendid Conifer has been so recently introduced into cultivation that we feel a slight hesitancy in extolling its merits as highly as they doubtless deserve ; but, be- ing a native of our own country, and also possessing so many excellences to recommend it to the notice of plant- ers, we may be excused for our great partiality to it. According to Nuttall : " It was discovered by Dr. Coul- ter on the mountains of Santa Lucia, near the Mission of San Antonio, in the 36° of latitude within sight of the sea, and at an elevation of between 3000 and 4000 feet above its level. It was accompanied by the P. Lambertiana" Gordon, in describing this pine, remarks : " It is also plentiful in other parts of California, particularly on the * Cerusta,' an ascent from San Luis Obispo, on the brow of the mountain." It forms a large tree, from 80 to 100 feet in height, with large, spreading branches, and a trunk 3 or 4 feet in diameter. The magnificent, long, glaucous green leaves of this pine cannot be excelled in beauty ; and the immense size, as well as the curious structure of the cone, fully entitles it to consideration. This latter feature is thus noticed by Nuttall : " Travellers compare them for magnitude to sugar loaves, which they resemble in form, suspended, as it were, from forest trees." The large, nut-like seeds contained in these cones are said to be very excellent and nutritious, although not equal in size to those of P. Sabiniana. We are not prepared at present to speak confidently of its hardiness, but, judging from experience and what THE PINE SUB-FAMILY. 117 we could obtain from other cultivators, think that on suitable, light, well-drained soil and in a favorable situa- tion, this species will eventually succeed in the southern portion of the Middle States, and probably may thrive in in a still lower temperature than we anticipate. That such may be the case we sincerely desire, as the surpassing beauty of our California pines is unexcelled in the world. Owing to the want of sufficient knowledge in respect to this tree, Loudon, in his Arboretum, places it as a synonym of the P. Sabiniana / but more recent investigation has proven it essentially distinct, and it has been designated as a separate species. 25. P, ponderosa, Douglas. — HEAVY-WOODED PINE. — Syn. P. Beardsleyi, Murray / P. Engelmanni, Torrey / P. Benthamiana, Hartweg. — Leaves, from 9 inches to 1 foot in length, short sheaths, broad, crowded, flexible, tor- tuous, and deep green color. Cones, 3|- inches long, ovate, reflexed, clustered, short-peduncled ; with the long, flat- tened scales armed with a small, sharp, recurved prickle. Seeds, rather small, with long,, yellowish-brown wings. Buds, cylindrical, long, tapering gradually to an obtuse point, and covered with a light glaucous bloom. A fine hardy species from our Pacific coast, growing, according to Gordon, " 100 feet high and 4 or 5 feet in di- ameter, with 30 or 40 feet of the stem free from branches ; " whilst those observed by Nuttall were "growing in a poor soil, and not more than 12 to 20 feet high." Dr. Parry found it " common through all the lower valleys and less elevated districts of the mountains, associated with Abies Douglasii and A. Menziesii / a most valuable timber tree." It is very common through some districts in Northwestern America, particularly in portions of Oregon, where Doug- las found it growing in large quantities on t*he banks of the Spokane and Flat-head Rivers, and near the Kettle Falls of the Columbia River. In the Rose River Valley, 1L8 THE BOOK OP EVERGREENS. in California, it is very abundant, and is there chiefly con- fined to the low alluvial soils, where it develops its full proportions. As an ornament we are rather inclined to believe it will not prove so popular as many others of our new Rocky Mountain Pines, owing to the coarse and somewhat open appearance of the tree. Yet, on the other hand, its re- markable vigor, excessive hardiness, and dark green foli- age, will certainly weigh in its favor, and may eventually counterbalance all obstacles to its becoming a favorite kind. Nuttall appears to be very sanguine in regard to its future usefulness in cultivated grounds. He says: " The tree has proven quite hardy and of a rapid growth, both in the climate of London and Edinburgh. It has a very elegant appearance even as a young tree, and seems to surpass all others in strength and luxuriance." London concludes his description of this tree as follows : " Pinus ponderosa, which is, perhaps, more hardy than P. Pinaster, and is of equally rapid growth, has a noble appearance even when a young tree ; and together with P. Sabiniana and P. Coulteri, equally noble trees, and ap- parently as hardy and of as rapid growth, well deserves a place in every pinetum." The timber is excellent and remarkably heavy, and in those sections where it attains a large size, it will prove very valuable on this account. 26. P. radiata, D. Don. — RADIATED-SCALED PINE. — Leaves, from 3^- to 4 inches long, from short, smooth sheaths; crowded, slender, twisted, dark green color. Cones, 6 inches long, ovate, solitary, or in small clusters, incurved, pendulous, with thick, truncate, obtuse scales, terminating in a blunt point. Seeds, small, very dark, with long wings. Cotyledons, 7 to 8. Although our experience with this tree has been so very discouraging, we nevertheless include it in our list for the benefit of those who desire to test its availability. We THE PIXE SUB-FAMILY. 119 have tried it in various situations, with and without pro- tection, but unfortunately it perished in every case ; and notwithstanding we have tested it several seasons, we have met with unvarying failure, and are therefore com- pelled to relinquish our attempt, however well it may suc- ceed in other soils and situations. It was discovered by Dr. Coulter in Upper California in latitude 36°, near the level of the sea and growing close to the beach, where it attained the height of 100 feet, beautifully furnished with branches close to the ground. The fact that it is a sea side plant may be the reason why our plants do not flourish. Sea air and the peculiar forma- tion of the soil to be found in such localities being neces- sary to its permanent success, it should be tried by those living in suitable localities. Were this tree entirely hardy here, it would be, without doubt, one of the most desirable of the Californian pines. The timber is tough and of first quality, which has caused it to be in great demand, especially for boat-building, large quantities being annually used for that purpose. The branches of this pine are very numerous and slen- der and covered with smooth, light colored bark ; the buds, small and very resinous. 27i P. rigida. Miller. — PITCH PIXE. — Leaves, from 3 to 5 inches long, from very short sheaths, crowded, rigid, flattened, mostly dark-green color. Cones, ovoid-conical, or ovate-oblong, sessile, from 1 to 3£ inches long, mostly solitary, occasionally in clusters of 3 or 4, very peristent ; the scales terminating with a small, recurved, stout prickle. Seeds, small. This native species, so common to the middle portions of our country, we do not consider one of our finest trees for lawn planting, being frequently devoid of that beauty of outline and compact habit of growth so neces- sary in an ornamental Conifer. It forms a medium sized tree, from 30 to 70 feet in height, with dark, rugged looking 120 THE BOOK OF EVERGREENS. bark, and generally of rather feeble growth. It inhabits light, sandy soils, or dry, rocky situations, excepting in some sections near the sea-coast, where it is often found growing in low, marshy grounds, and in such the size of the tree is very greatly increased. Although this species is so frequently found growing in low, swampy grounds, particularly in the "Cedar Swamps " of Maryland and Delaware, it is often seen flourishing in situations that are exactly the opposite. Within sight of where we are writing is a large group of these pines in- termingled with the P. inops, which are growing on a dry, slaty ridge, with a very slight depth of soil The wood is of little value for lumber, owing to the large number of knots throughout its entire length, as well as to the preponderance of sap ; but much depends upon the quality of the soil from whence it is taken; — trees growing on light, gravelly, or rocky soils furnishing a heavy, resinous timber^ whilst, on the contrary, those on damp, alluvial lands produce a soft and light wood. In any situation, however, it is much inferior to others of our native species. The wood throws out an in- tense heat in burning, and is sought after for certain pur- poses. It also furnishes a liberal supply of tar, although not of sufficient value for extensive manufacture. Var. serotina, London. — POND PIXE. — Syn. P. sero- tina, Michaux, Chapman, &c. — This pine has been re- duced by Prof. Gray to a mere form of the P. rigida. Loudon also describes it as a variety and Pursh suspected the same, although Gordon, in England, and Chapman, in this country, recognize it as a distinct species. The only apparent differences in the two are, that the variety produces ovate or roundish cones, generally oppo- site, and mostly solitary, and has rather longer leaves. We are always pleased to have our authorities consolidate two species, when they appear so nearly allied as the above. THE PINE SUB-FAMILT 121 28i P. Sabiltiana, Douglas. — SABINE'S PINE. GREAT PRICKLY-CONED PINE. — Leaves, from 10 to 12 or 14 inches long; from long, light-brown, shining, membranaceous sheaths; serrate, slender, acute, recurved, flexuose, and glaucous-green color. Cones, from 8 to 10 inches long, and 6 inches in diameter ; ovate, echinate, in large clusters, recurved, very persistent ; with large spathulate or awl- shaped, incurved scales, ending in a strong, sharp point. Seeds, large, oblong, tapering to the base, with a thick, hard, brown integument, and a short, stiff, yellow wing. Cotyledons, from 7 to 12. This magnificent native Conifer is one of -the very finest of the family, and was discovered by the lamented explorer, Douglas, who named it in honor of a former secretary of the London Horticultural Society, Joseph Sabine, Esq. It was first found in the parallel of 40°, on the Cordilleras of California, at a very high elevation, and only 1600 feet below the region of perpetual snow, and was afterwards discovered growing nearer the sea-coast at a lower, eleva- tion, but more even temperature, in the parallel of 37°. It is also found at El Toro, a high mountain near Monterey, and, according to Dr. Gairdner, on the Fallatine Hills of the Wahlamet, as well as in many other places in Upper California and Oregon, but almost invariably upon the summits of high elevations on the mountains. The beautiful, regular form presented by a perfect speci- men of this tree is all that we could wish for in that respect ; and when to this is added a compact mass of deep green verdure, gracefully extending to the ground, we do not know of anything more desirable. The cones are also not only exceedingly curious, but handsome and useful ; producing seeds that are in great esteem among the natives as food, and nearly as pleasant as almonds, excepting that they leave behind a slightly resinous taste. Nuttall, in his description of this species, says, " The stems of these pines a»re of a very regular form, and grow straight and tapering to the height of from 40 to 140 6 122 THE BOOK OF EVERGREENS. feet, and are from 3 to 12 feet in circumference, when standing apart, clothed with branches down to the ground." Other authors state that on the western Cordilleras of New Albion, at a great elevation, they grow from 100 to 150 feet in height, and from 2 to 5 feet in diameter. But all unite in praising its exceeding beauty as a specimen tree. The xwood is white, soft, even-grained, and, perhaps, not very durable." This species yields a copious supply of resin when punctured. 29. P. Taeda, Linnceus. — LOBLOLLY PINE. OLD-FIELD PINE. FRANKINCENSE PINE. — Leaves, 6 to 10 inches long, from elongated sheaths, rigid, slender, rather obtuse, and light-green color. Cones, 3 to 5 inches long, oblong, solitary, or in pairs, somewhat truncate at the base ; the scales terminated with short, sharp, incurved prickles. Seeds small. This is another of our native pines that is confined to the Atlantic States, and found frequently growing in com- pany with the P. australis, although mostly in damp soils, not too heavy. According to London, " it was introduced into England before 1713, by Bishop Compton." It forms quite a large tree under favorable circumstances, ranging- from 50 to 100 feet high, with very thick and deeply furrowed bark. In the light barren soils of Virginia, it may be frequently met with as a somewhat stunted large shrub. "All the woods in the Southern States," says Pursh, " seem to be seeded with it ; for, when any piece of clear land is neg- lected for a length of time, it is speedily covered with this species ; and hence its name among the inhabitants, of Old-field Pine. It is difficult, and in some cases almost impracticable, to recover the lands which have been over- run with young pines of this species, as the ground appears to have lost all fertile properties for any othef vegetable than these trees." Michaux says, " In the same parts of Virginia, this species THE PINE SUB-FAMILY. 123 exclusively occupies lands that have been exhausted by cultivation ; and amid forests of oak, tracts of 100 or 200 acres are not unfrequently seen covered with thriving young pines." There is a plant of this species in our immediate neigh- borhood, which is at least 20 feet high,and stands the sever- ity of our winters without any serious injury. In our own grounds, a plant now 7 feet high, and which was raised from seed here, has so far escaped with little detriment to its outline. We cannot, however, recommend it for orna- mental purposes, excepting in large collections, as it is much inferior in beauty to our White Pine and others of the genus. The timber is not valuable, owing to its propensity to warp and decay, but is nevertheless used in large quan- tities for secondary purposes. Its resinous properties are not equal to those of the P. australis, and its wood is less valuable for fuel. 30. P. tubercnlata, D. Don. — TUBERCTJLATED-CONED PINE. — Syn. P. Californica, Hartweg. — Leaves, 4 to 5 inches long, from short smooth sheaths, rigid, flattish, and bright green color. Cones, 4 inches long, oblong-conical, mostly in small clusters, very persistent, sessile, pendulous, and tawny-gray color ; . scales quadrangular, truncate, with an elevated apex, and armed with a stout, short prickle. Seeds very small. This species, whose existence was much doubted by Nuttall, is a native of California and was first discovered by Dr. Coulter to the south of Monterey, near the level of the sea, intermixed with P. radiata. Hartweg found it on the Santa Cruz Mountains, sixty miles to the north of Monterey, and Jeffrey mentions meeting with it at an elevation of 5000 feet. It is a rather small tree, seldom attaining a greater height than 30 or 40 feet, with a trunk 8 or 10 inches in diameter, and is likewise of very slow growth, requiring 124 THE BOOK OF EVERGREENS. many years to attain its full size. The specimen in our own collection is so small that we cannot report any very satis- factory experience with, it in respect to hardiness, but from the situation where it is mostly found, and from its being so closely allied to P. insignis and P. radiata, both of which are exceedingly unsatisfactory here, we are inclined to be somewhat skeptical as to its future usefulness with us. Nuttall says it is nearly allied to P. patula, the Long- leaved Mexican Pine of Schiede, which is also tender; we have, therefore, not a very flattering prospect before us in attempting to acclimate it. Timber, very hard, and dark red color. SEC. III.— QUIHTJE.— FIVE LEAVES IN A SHEATH. 31. P« aristata, Engelmann. — AWNED-CONED PINE. — Leaves from 1 to 1^ inches long, crowded from the axils of ovate, acuminate, brittle, at first light-brown scales, which, persisting longer than the leaves themselves, cover the branches with their rough blackish remains ; incurved, entire, abruptly acute, light-green on both sides. Cones, 2|- to 2£ inches long, oval, resinous, dark purplish-brown color; scales, terminating in a slender, incurved mucro. Seeds, small. Cotyledons, 7. We introduce this new Conifer in this place, on account of its undoubted hardiness and adaptability to the climate of the Middle States. Although of very recent introduc- tion, young plants are now being tested, both in England and this country, and we look forward with great interest to its permanent and successful cultivation. It was discovered by Dr. C. C. Parry, growing in the alpine regions of Colorado Territory, above the limits of Plnus flexilis, Abies Engelmannii, and other sub-alpine Conifers ; indeed, it first makes its appearance, in ascending THE PINE SUB-FAMILY. 125 the slopes, where the other pines become mere stunted shrubs. "We make the following extracts from Dr. Engelmann's paper in the Transactions of the St. Louis Academy of Sciences : " On alpine heights, between 9,200 and 11,800 or 12,000 feet high, on Pike's Peak and the high mountains of the Snowy Range, Dr. Parry, 1861 and 1862, Messrs. Hall and Harbour, 1862. Also on the heights of the Cooche- topa Pass, nearly south-west of Pike's Peak, (altitude over 10,000 feet,) where Captain Gunnison discover- ed, in 1853, what seems to be this species without fruit, (see Pacific R. R. Rep., II., p. 130) ; the leaves which I could compare are those of our plant. Flowers end of June and beginning of July. Flourishing best in the Fig. 16. — PINUS AKISTATA. higher elevations, and never descendingjbelow 9,000 feet, in its lower ranges not ripening its fruits as well as on the bleak heights ; this truly alpine species — in this respect our representative of the European P. pumilis — character- izes the highest belt of timber on the peaks of Colorado. On sheltered slopes a tree 40 or 50 feet high and from 1 to 2 feet in diameter, it becomes a straggling bush, prostrate, and almost creeping, on the bleak summits of the high ridges." In allusion to its apparently very slow growth, Doctor Engelmann says : " Its growth, at least in the latter local- ities, is exceedingly slow, as a stick of scarcely more than one inch in diameter, brought back by Dr. Parry, shows nearly fifty annual rings, some of them ^ of a line, and 126 THE BOOK OF EVERGBEENS. none more than J of a line wide." The same author also states that the wood is white, tough, not very resinous ; and that a tree of two feet thickness, at " the above rate, indicates an age of over 1,000 years; but the annual rings of larger trees growing in favored situations are wider, and, if a specimen sent by Dr. Parry is not mislabelled, sometimes as wide as % line, giving the largest trees a probable age of from 500 to 800 years. " The branches are spreading, very often many of them twisted, stunted, or dead; the larger branches and the stem itself frequently covered with young branches or shoots, which seem to keep life in the old trunk. The bark is thin and scaly, even in older trees not more than 3 or 4 lines thick, of a light grayish-brown color ; that of younger branches, smooth, with many large vesicles con- taining a clear fluid balsam, which remains between the layers of the old bark." The leaves of this pine are, without doubt, more per- sistent than those of any known species, as accurate ob- servations have proven that they have remained on the tree for a period of 16 years. 32. P, Cembra, Llnnmus. — Swiss STONE PINE. — Leaves, 2 to 3 inches long, from a medium sized decidu- ous sheath, triangular, slender, straight, crowded, glaucous, dark green color. Cones, 3 inches long, ovate, erect, with obtuse, slightly hooked scales. Seeds, very large, edible, wedge-shaped, wingless, with hard shells. Cotyledons, 11 to 13. A handsome, hardy species, that was introduced into cultivation about the year 1746, from the highest regions of the Alps, between 4000 and 6000 feet elevation, and forming quite large trees about 50 feet in height. From the Tyrol to Mt. Cenis, in Austria, it is also frequently met with forming vast forests of the darkest and most sombre verdure. Pallas mentions this species as a lofty THE PINE SUB-FAMILY. 127 tree growing 120 feet in height ; but perhaps he may have been mistaken, as his account differs from that of others. The tree forms a handsome, regular cone, clothed with branches to the ground, very dense in its growth, as hardy as any of our native species, and in a group of pines, the darkness of its foliage contrasts finely with the lighter green of other members of this family. " According to Lambert," says Loudon, " the flowers have a more beauti- ful appearance than in any other species of pine, being of a bright purple ; and the unripe full-grown cones, he says, have a bloom upon them like that of a ripe Orleans Plum." The slowness of its growth, however, is to be regretted, for were it otherwise, we could without reservation recom- mend it for extensive cultivation ; but, notwithstanding this unpopular obstacle, the Stone Pine is deservedly in favor for creating certain effects in landscape gardening, which are unobtainable with any other species. Loudon says: "In England, it is a formal, and we do not think it can be considered a handsome tree ; it presents to the eye a multiplicity of tufts of leaves, piled up one above another, of the same size, and equidistant, and everywhere of a rather dull green color. The uniformity of shape is nowhere broken, except at the summit, where alone the cones are produced ; and hence, as a mass, it may be characterized as formal and monoto- nous, without being grand." The same author subsequently remarks : " The summit of the tree, however, and its purple cones, we acknowledge to be truly beautiful. That we may not run the slightest risk of injuring this tree, we may mention that Mr. Lam- bert, so far from entertaining the same opinion as we do re- specting it, looks upon it as one of the handsomest trees of the whole genus" An excellent quality in the Stone Pine is its adaptability to almost all kinds of soils and situations, and even Lou- don is forced to admit this when he remarks : " Though 128 THE BOOK OP EVERGREENS. the Cembrau Pine, as we have seen, will grow in the poorest soils and in the most elevated and exposed situa- tions where no other pine or fir will exist, yet it will not grow rapidly except in a free soil, somewhat deep, and in a dry subsoil." The timber is fine-grained and very soft, thus allowing of its extensive use for carving, and, in some sections of Switzerland, it is in demand for the manufacture of toys of various kinds, especially among the Helvetian shepherds. It also furnishes a liberal supply of fragrant resin. Var, Sibirica, London.— Pallas says this form is not found beyond the Lena, and is a lofty tree. It differs from the species in having shorter and lighter green leaves ; al- so, producing longer cones, with larger scales. It resem- bles somewhat the Scotch Pine, but has a smoother and grayer bark. It is a native of Eastern Siberia, and has, like the species, large, edible seeds. Var, pygmaea, Fischer. — Syn. var. pumila, Endlicher, etc., etc. — This is a handsome and desirable little dwarf, seldom exceeding 2 or 3 feet in height, although old speci- mens are known that are 5 or 6 feet high. It has very short leaves, small, roundish cones, and small seeds. The native habitat of this variety is on rocky eminences and dry, sterile spots, which $ in many instances, are almost de- void of other vegetation. Loudon says : " There is a plant at Dropmore which has been twenty years planted, and, in 1837, was not more than six inches high, which we pre- sume to be this variety. The same may be said of a tree in Hopetoun Gardens, near Edinburgh, said to be upwards of 100 years old, and which, in 1836, measured only 5 feet 6 inches high." 33, P. excelsa, Wattich. — BHOTAN PINE.— Syn. P. Strobus excelsa, Loudon, etc. — Leaves, from 5 to 7 inches long ; with short, caducous, imbricated, membranaceous sheaths ; slender, mucronate, crowded, glaucous green THE PINE SUB-FAMILY. 129 Fig. 17. — PINUS EXCELSA, HALF THE NATURAL SIZE, FROM A SPECIMEN FRUITED BY A. FIOT, BETLEHEM, PA. 6* 130 THE BOOK OF EVEBGREEXS. color. Cones, from 6 to 9 inches long, 2 inches in diame- ter, cylindrical, smooth, pendulous, pedunculate, clustered ; with broad, thick, wedge-shaped, coriaceous, closely imbri- cated scales. Seeds, mostly small, ovate, compressed, with a hard, dark colored testa, and a membranaceous, re- ticulated, oblong-obtuse wing. This beautiful pine, owing to an unfortunate habit of blasting, is not so popular at the present time as it de- serves to be. The high cultivation given it by most plant- ers has, in the majority of instances, resulted in failure, and consequently the tree is condemned, when the fault lies in the soil, which caused a superabundance of weak, unripened wood. Such is the idea we have formed upon the subject, and in every case that has fallen under our notice an examination into the cause of failure has re- sulted in establishing this view. The Bhotan Pine is a native of Nepal and Bhotan ; and on the Himalayas, at elevations of from 6000 to 8000 feet, (and occasionally even to 11,500 feet,) it flourishes with remarkable vigor, forming entire forests along the warmer slopes. Perhaps the finest specimens are to be found near the Shatool Pass, and below Shansoo, in Kunawur, where these trees are occasionally found 150 feet in height, generally branched to the ground and forming large, spreading cones. We consider this species one of the most desirable of the family for parks and pleasure grounds, as its remark- ably graceful, drooping habit, (which has given it the name of " Drooping Fir " by some Himalayan travellers,) is peculiarly appropriate for single specimens ; and as it is perfectly hardy, withstanding the utmost severity of our winters, it should be included in every collection, how- ever small. The general appearance of this tree reminds one of a handsome White Pine, and indeed the resemblance be- comes more perfect upon a nearer inspection, as they are THE PINE SUB-FAMILY. 131 very closely allied. But the latter is decidedly inferior in point of beauty, the Bhotan Pine having much longer and more glaucous leaves, as well as a more dense and compact habit of growth. In fact, these two species ap- proach very nearly to each other in a botanical classifica- tion, the main point of distinction being, according to Lambert, in the crest of the anthers. We have occasionally also seen the White Pine blast in the same manner as this species, especially when growing very luxuriantly in a rich, deep soil ; but the propensity for vigorous, unripened growth is more marked in P. excelsa, and therefore the remarks in Sargent's late edition of Downing's Landscape Gardening, in regard to this characteristic, are worthy of much respect. The idea of that author is precisely similar to that which has been forced upon us by experience. Some attribute the early decay of this tree to the presence of some of the wood- boring insects, but although we have known instances where such was the case, we believe them to be rare. The great difference in soil and situation has caused a dissimilarity in the growth of this species, so that varie- ties with shorter or more rigid leaves have been fre- quently introduced as distinct; but these have all very properly been placed under the species. The P. excelsa furnishes a soft, compact, and white lum- ber, very similar to the P. /Strobus, but perhaps not so valuable, owing to the abundance of resin. The turpen- tine extracted from the wood is very copious, exceedingly fragrant, and useful. It is said to be so pure and limpid that the slightest incision in the tree causes it to flow freely. 34. P. flexilis, James. — AMERICAN CEMBRAN PINE. — Leaves, from 1-J- to 2£ inches long, rarely 3 inches long, from lanceolate, deciduous sheaths, rigid, entire, acute, densely crowded. Cones, sub-cylindric, tapering to the end, from 4 to 5 inches long, 2 inches in diameter, short peduncled, semi-pendulous (Dr. Parry,) clustered. Scales, 132 THE BOOK OF EVEKGEEENS. thick, ligneous, obtuse, loose, squarrose, lowest sterile ones recurved, yellowish-brown color. Seeds, rather large, ir- regularly ovate or obovate, with persistent, sharp, keeled margins, representing minute wings. Cotyledons, 8 or 9. This species, the identity of which has been questioned for the last forty years, is now happily assigned the position that its discoverer claimed for it. This question has been satisfactorily solved by the researches of Dr. Parry, who had excellent opportuni- ties of examining specimens, and was enabled to correct a few inaccuracies that occurred in pre- vious descriptions. It was discovered by Dr. James on the Rocky * Mountains, growing mostly on the sub-alpine tracts, and extending al- most to the utmost limits of vegetation. Mr. H. Engelmann collected it on the head waters of the Platte, and it has been noticed by several other explorers. Dr. Parry, in his Ascent of Pike's Peak, remarks that " the vertical range of this species, as observed between latitude 38° and 40° W., is from 7,000 to 11,000 feet above the sea. It rarely occurs in large r. 18. — PINUS PLEXILIS, FROM A ROCKY MOUNTAIN SPECIMEN, COLLECTED BY DOCT. PARRY. THE PINE SUB-FAMILY. 133 "bodies of timber, but is mostly of scattered growth, being associated at its lowest range with Pinus ponderosa, and Pinus contorta, and at its upper limits with Pinus aristata and Abies Engelmanni.^ In Dr. Engelmann's account of this tree he gives the following statistics in regard to its size : " P. flexilis, the American representative of P. Oembra of the old world, is a middle sized tree, usually 30 to 50 feet high, though Fendler, a good authority, saw it near Santa Fe, 60 to 80 feet high ; Dr. Bigelow's trees, of the height of 100 to 130 feet, on the San Francisco Mountain, must belong to some other five-leaved species." The same author remarks : " In Colorado it is a fine tree with tapering trunk and oval outline, branching al- most from the base, lower branches horizontal, upper ones ascending ; wood, white, hard, annual rings from -J to -J- line, on an average J line wide ; trees become in 250 or 300 years about one foot thick." Dr. Parry states : " In general appearance it very closely resembles our P. Strobus, from which it differs mainly in its shorter and stouter entire leaves, more branching mode of growth, as well as in the yellowish-brown cones, with peculiar thickened ligneous scales." In Dr. James' account of this species, he stated the cones were " erect ; " but Dr. Parry states they " are inclined to be pendulous." We make the following extracts from Dr. Parry's de- scription : " The seeds are nearly equal in .size to those of the New Mexican Nut Pine (P. edulis^) of an irregular, oval form, 4 to 5 lines long, and possess similar edible qualities. In addition to other peculiarities of this pine may be noticed its slowness of growth ; thus, on a small trunk of 7} inches in diameter there were 232 annual rings. Its wood is soft, of fine texture, the heart-wood inclining to a yellowish cast. The flexibility of its branches, on which Dr. James founded its specific name, 134 TE(E BOOK OF EVERGREENS. is partly due to the thickness of the elastic bark of the smaller twigs." We place great reliance upon many of our new native pines, but on none more than this. Coming from an elevated and exposed region we may look for its future usefulness here. 35. P. Lambertiana9 Douglas. — LAMBERT'S PINE, GIGANTIC PINE. — Syn. P. Strobus Lambertiana, Loudon. — Leaves from 3 to 4 or 5 inches long, from short decidu- ous sheaths, rigid, slightly denticulate on the margin, bright green color. Cones, from 12 to 14, and even 16 inches long, 4 inches in diameter, cylindrical, gradually ta- pering to a point, erect when young, pendulous at maturi- ty, destitute of resin, dark brown color ; scales, loosely imbricated, dilated, rounded above, devoid of prickles. Seeds, oval, large, sweet and nutritious ; with a large, dark colored wing. Cotyledons, 12 or 13. This magnificent Conifer was discovered by Douglas, in the year 1825, near the source of the Multnomah Riv- er, on our northwestern coast. The discoverer states: "The trunk of P. Lambertiana grows from 150 feet to above 200 feet in height, varying from 20 feet to near 60 feet in circumference. One speci- men which had been blown down by the wind and which was certainly not the largest, was of the following dimen- sions: Its entire length was 215 feet ; its circumference, at 3 feet from the ground, was 57 feet 9 inches ; and at 134 feet from the ground, 17 feet 5 inches. The trunk is unu- sually straight, and destitute of branches about two-thirds of its height. The bark is uncommonly smooth for such large timber, of a light brown color on the south, and bleached on the north side." We take great pleasure in recommending this superb pine to the notice of our arboriculturists, believing it to be one of the finest of the genus that has been fully tested. It stands the utmost rigors of our winters without any THE PINE SUB-FAMILY. 135 protection, and like the closely allied P. Strobus, is a rapid- growing and graceful tree. When young, these two species show a marked resemblance to each other, but as the plants increase in size the distinction soon becomes apparent. The timber of the P. Lambertiana also closely resem- bles that of the White Pine in being white, soft, and light ; consequently it is easily worked.- It produces an abun- dant supply of resin, which is remarkably clear and pure, and when taken from a partially burned tree, it acquires a very sweet and pleasant taste, and is used by the natives as sugar to sweeten their food. The seeds, being very large and nutritious, are consequently of much value, the natives using them either fresh as gathered from the tree, or roasted and prepared into rough cakes during the winter. 37. P. monticola, Douglas. — MOUNTAIN PINE. — Syn. P. Strobus monticola, Loudon. — Leaves, from 3 to 4 inches long, from short, imbricated, very deciduous sheaths; obtuse, smooth, obsoletely crenulated on the margin, glaucous-green color. Cones, 7 inches long, If inches broad, cylindrical, smooth, obtuse at the apex, short peduncled, resinous, with loosely imbricated, pointed, spineless scales. Seeds, small, with an ample wing. The resemblance between this species and the P. Strobus has given the former the common name of " Short-leaved Weymout/i Pine" which was considered by Nuttall as correct, and mentioned by him in his sequel to the North American Sylva, as a variety of that species. This opinion was also concurred in by Loudon, who described it as a variety of P. Strobus. We think, however, its specific character is sufficiently distinct, and that Douglas was correct in his name. This opinion is also entertained by Gordon and other later writers. It forms a large-sized tree of 100 feet or upwards in height, with a more compact head than the White Pine, 136 THE BOOK OF EVERGREENS. and much shorter and more glaucous leaves. It is a " na- tive of the high mountains, at the Grand Rapids of the Columbia ; and in California, on the rocky banks of the Spokan River." (Loudon.) On Trinity Mountain, in Northern California, at an elevation of 7000 feet, it is found quite plentifully, growing on poor, sandy soil, which it greatly prefers, partaking of the same nature as the other allied species, such as P. Lambertiana, P. excelsa, P. Stro- bus, etc. ; and, in fact, a rich, damp soil is very unsuitable for this group, as is frequently instanced in their sudden death when in such positions. Situations of this nature should therefore be strictly avoided. We have been greatly pleased with this species, not- withstanding its resemblance to our old Weymouth Pine, — the leaves being shorter and more glaucous, and the form more compact and dense. Its hardiness is without doubt, and we think it altogether very desirable in a collection. The timber furnished by this species is similar in many respects to that of the White Pine, but more tough. 38, P, StrobllS, Linnceus. — WHITE PINE. WEY- MOTTTH PINE, (of the Europeans.) — Leaves, 3 to 4 inches long, from very deciduous sheaths ; slender, straight, soft, slightly glaucous. Cones from 4 to 5 or 6 inches long, cylindrical, somewhat curved, slightly drooping, short pe- duncled, with smooth, thin scales, devoid of prickles. Seeds, rather small, obovate, with a long wing. Cotyledons, 6 to 10. An old, well-known, and useful tree, that is found throughout the northern sections of our country, extend- ing from Virginia into Canada, but more plentifully in Maine, New Hampshire, Vermont, and Northern New York and Pennsylvania. The White Pine forms a large tree, from 100 to 160 feet in height, according to the situation in which it is found. In the extensive pine forests from whence such immense quantities of lumber are annu- ally taken, this species is, in many places, the only one THE PINE SUB-FAMILY. 137 seen for several miles ; and in such situations it generally presents a tall, naked stem, devoid of branches for at least two-thirds of its length, thus affording valuable logs. When cultivated for or- nament the real beauty of this tree becomes apparent, and although we cannot exactly coincide with the late A. J. Downing in all his views of this species, we, however, think it very hand- some and desirable. In com- parison with many other species, it is too open or devoid of branches to form a perfectly beautiful specimen. Its hardiness is proverbial, high winds being a greater enemy to it than extreme cold, and a damp, retentive soil far more injurious than a sandy, dry bottom. In fact, the White Pine will never arrive at that per- fection in a wet, undrained subsoil, that it would on a gravelly, porous one. There is a peculiar charm about this tree which makes it an indispensable com- panion around our homes, and we would as soon think of omitting evergreens alto- FiS- I^.-PINUS STROBUS. gether as to be without one specimen at least of the Wey- mouth Pine. The light, glaucous-green color of the foliage 138 THE BOOK OF EVERGREENS. contrasts beautifully with the other species, and when in motion is remarkably handsome, presenting as it does a happy commingling of green and silver, that is equalled by that of few trees. The long, slender leaves are so easily moved by the slightest breeze, that a constant sigh- ing and moaning is kept up, which has long been a theme with poets ; and although this peculiarity is not restricted alone to this species, we have always preferred standing by the side of our old favorite, and listening to this nat- ural JEolian harp in preference to any other. According to London, " Pinus Strobus was first cultivat- ed in England by the Duchess of Beaufort, at Badming- ton, in 1705. Great quantities were soon afterwards planted at Longleat, in Wiltshire, the seat of Lord Wey- mouth, where the trees prospered amazingly, and whence the species received the name of the Weyrnouth Pine." The lumber of the White Pine is quite as useful as that of any other species, notwithstanding the assertions of some of our transatlantic brethren to the contrary. It is soft, fine-grained, light, and very white, and is in use throughout our country. Although very liable to decay when improperly exposed, its other good properties fully compensate for this defect. The turpentine afforded by this tree is moderately abundant in particular situations, but not of sufficient value to make it an object of manu- facture. Var. alba, London. — Syn. P. nivea, JBootk, with other incorrect names, is very beautiful, and quite desirable in our collections.

In this chapter we desire to enumerate and describe briefly a few of the new and untested species, as well as those which have been thoroughly tested and proven to be entirely too tender for our climate in the Middle States; and in so doing we wish once more to explain our con- struction of the terms hardy and tender plants. On soils that are thoroughly drained, either naturally or artificially, many Conifers, such as the Deodar and Cryptomeria, will succeed very well in the neighborhood of Philadelphia, especially when planted in a warm and protected situation ; and yet the same plants, with equally generous treatment in soils that are retentive of moist- ure, such as a very heavy clay, are frequently denounced as tender and unfit for cultivation by others residing in the immediate vicinity. As very many Conifers are barely hardy enough to with- stand the severity of our winters at this point, a very few degrees further north entirely places them as undesirable, and thus many a well-meaning and strictly honest writer is frequently censured for recommending plants that his readers find, to their cost, tender and undesirable. Plants, therefore, may very justly be classed as hardy, variable, and tender. The first of these embraces such as are unexceptionably reliable ; in the second is comprised those species which it is neither good policy to discard, nor to recommend too highly ; and in the third, the undeni- ably uncertain kinds. It is indeed difficult to assign the true positions of many of our very finest Conifers as to hardiness, and therefore it should be the pleasure of every 140 THE BOOK OF EVERGREENS. arboriculturist to experiment and endeavor to ascertain the requirements of these trees. This subject is of such importance that, having been fre- quently misled ourselves, we desire to impress upon the minds of others the necessity of understanding the meaning of these terms ; and because a certain plant may not succeed with us, it is no reason that it may not with a more for- tunate neighbor, who has probably secured the condi- tions necessary for its success. Among these so-called tender species, there may possibly be some, especially those from the higher altitudes on the mountains of Mexico, that may eventually succeed in the warmer portions of the Middle States ; but in their gen- eral usefulness we place but little confidence, as our ex- tremely variable climate is so totally different from their even, although cold, situations. As our knowledge of most of the newly discovered Conifers is restricted entirely to the descriptions given by various authors, and principally to those of English writers, we do not feel willing to be held responsible for mistakes in nomenclature, when noticing such plants. Enthusiastic explorers are prone to the fault of renaming old species, not through any desire to impose upon the public, but in most instances by allowing their better judg- ment to be set aside, for the purpose of receiving that honor which is very justly bestowed upon the discoverer of a new species ; and such we are compelled to believe is the case in the new Mexican Pines of Roezl. This dis- coverer has introduced the names of about 120 new species, but which, according to the recent examinations of Gordon, and others, has resulted in obtaining but five that are en- tirely new and previously unclescribed. Those considered as good species are as follows : 38. P, Lawsoni, Hoed. — A medium-sized tree from the higher mountains. THE PINE SUB-FAMILY 141 39. P. protuberans, Roezl. — Growing upwards of 100 feet high on the mountains, at an elevation of from. 9,000 to 10,000 feet. 40. P. Buonapartea, Roezl— Grows 130 feet high, with the b ranches in regular whorls. This is the "Pino Real" or Royal Pine of the Mexicans, and is found at ele- vations from 11,000 to 12,000 feet. It is a splendid species. 41. P. cornea^ Roezl. — A new and distinct species from the Popocatapetl, in Mexico, at an elevation of from 10,000 to 11,000 feet; said to be fine. 42. P, Regeliana, Roezl. — One of the very finest of Mexican Pines, found on the mountains at an elevation of 8,000 or 9,000 feet. Leaves, 10 to 11 inches long, and slender. The remainder of RoezPs pines are thus classed by Gor- don in his recent supplement to the Pinetum : Fourteen are synonyms of P. Hartwegii. Four " One Four Three Eleven Five Ten Five Eighteen Three Ten Four Seven Five Five One One P. protuberam. P. Orizabce. P. Buonapartea. P. Loudoniana. P.filifolia. P. Wincesteriana. P. Teocote. P.

Three kinds are not sufficiently known, either to estab- lish their claims as distinct species, or to determine of which they are synonyms. Our attention will next be directed to the older species of Mexican Pines, as well as to those of the Eastern Con- tinent that we suppose to be too tender for cultivation in the open air with us. Belonging to the Since section, are the following, viz. : 43. P. Merkusii, Vriese. — Is a very tender species from the mountains of Sumatra, Cochin-China, Borneo, etc., where it grows about 100 feet high. 44. P. Persica? Strangways. — Is from the south of Persia, where it forms a large tree with rather short, slen- der branches, and numerous, stiff, deep green leaves. Gordon mentions a doubtful species from Palestine and Arabia, called by Sieber P. Arabica, and which is prob- ably nothing more than jP. JETalepensis. In the Ternaice section we have 45. P. Canaricnsis, Smith. — Is from the Canary Islands, growing 60 or 70 feet high, at an elevation of from 4,000 to 6,000 feet, and forming large forests. This pine makes a beautiful object when grown in pots and sunk in the ground. 46. P. Cdlllis, Engelmann. — Syn. P. cembroides, Gordon. — Must not be confounded with the P. cembroides of Zuccarini, which latter plant is the true P. Llaveana of Schiede, according to Gordon's classification. Prof. Torrey says of this pine, in Pac. R. R. Report : " Rocky places on the Llano Estacado ; also near Hurrah Creek, New Mexico, Sept. 20 ; with ripe seeds. Near Bill Williams' Mountain, Jan. 5. A tree 40 to 50 feet high, called Pinon by the Mexicans, and Nut-Pine by American travellers. It is found from 150 miles east of THE PINE SUB-FAMILY. 143 the Rio Grande to the Cajon Pass of the Sierra Nevada. How far it occurs to the southward, we have not been able to ascertain." Dr. Bigelow, in his description of this tree, says : " It seldom grows large. A little west of the San Francisco mountain, and at the Cajon, it is found from 40 to 50 feet high, but further east it seldom attains more than 24. Its usual height, however, is about 30 feet. The nut is sweet and edible, about the size of a hazel-nut." We are pleased to add that young plants of this species have stood out in the open air near Philadelphia, for the three past winters, without injury. The leaves are quite frequently in pairs. 47. P. Chihuahuana, Wislizenus. — Is a tree of some 30 or 35 feet in height, and is found on the mountains of Northern Mexico at an elevation of 7,000 feet. 48. P. insignis, Douglas. — OREGON PITCH PINE. — This is one of the most beautiful species belonging to the family, and lives in the open air one or two winters if moderately mild. In England it is quite hardy and highly valued. It is a native of California, growing from 80 to 100 feet high. 49. P. insularis, Endlicher. — Is the Timor Pine from the Philippine Islands and Island of Timor. Its long, slender, dark-green leaves, are very beautiful, but its spe- cific character remains somewhat in obscurity. 50. P, Llaveana, Seheide. — Syn. P. osteosperma, Wislizenus ; and P. cembroides, Zuccarini. — Belongs to the large edible-seeded class of pines, of which the P. Pinea is the type. It is a native of the barren and sterile hills of Mexico, where it forms a low, spreading tree scarcely ever exceeding 20 feet in height. It is frequently found in cultivation for the value of its fruit. Tender here. 144 THE BOOK OF EVERGREENS. 51. P. longifolia, Roxburgh. — LONG-LEAVED PINE. — This species forms a splendid plant for pot culture, but is entirely too tender for out-door cultivation in our climate. It is a native of the Himalayas, growing from 40 to 100 feet in height. It produces an abundant supply of very fragrant resin, and on this account the young plants are very liable to be destroyed by field mice. A few years since we had several fine specimens in a cold frame, along with other species of the Conifer® ; but upon examination in the spring found every vestige of bark eaten from our plants of P. longifolia^ whilst the others remained un- touched. 52. P, Parryana, Gordon. — Is from the Sierra Nevada in Upper California, forming a large-sized tree with long, slender, wavy leaves, and bright, glossy, yellow cones. It resembles P. Benthamiana, and may prove hardy here. 53. P, patula, Schiefle. — Is one of the most ex- quisitely beautiful trees known to botanists, and in a large pot or tub forms an excellent representation of a fountain. It is quite abundant in some parts of Mexico, particularly in the colder regions, where it grows to the height of from 60 to 80 feet, and forms the most perfect specimen of a graceful, drooping Conifer that one can imagine. A specimen of this species in our own collection, after having arrived at the height of 6 feet, was accidentally overlooked in watering, and consequently soon perished ; thus, by a dearly bought experience, we learned a useful lesson in regard to growing Conifers in pots. Var. stricta, Bentham, and var, macrocarpa, Schiede. — The former with shorter and stiffer foliage, and the lat- ter with very large cones, are possibly not more handsome than the graceful form of the species. 54. P. Pine can a , Gordon. — Is another of the graceful Pines for which. Mexico is so justly celebrated. It gen- THE PINE SUB-FAMILY. 145 erally forms a rather large tree of about 60 feet in height, and although the leaves are of but moderate length, the branches and branchlets are remarkably long, slender, and drooping, and present a beautiful effect. 55. P, Sinensis, Lambert— Qf which there are three or four synonyms, is from China and Japan, and is found growing very plentifully, particularly on the more elevat- ed situations. It is about 50 or 60 feet in height, although occasionally not over 30 or 40 feet in some sections. 56. P. Teocote, Schiede. — This is the Candle-wood Pine from the mountains of Mexico, and is a tall, resinous species of about 100 feet in height, with stiff branches, very densely covered with leaves. Among the tender and uncertain species belonging to the Quince section, are the following : 57. P. Apulcensis, Lindley. — One of Hartweg's dis- coveries on the mountains near Apulco, in Mexico. It grows about 50 feet in height, with strong, irregular branches, and slender, wavy, glaucous leaves. 58. P. Ayacahuite, Ehrenberg. — Another Mexican species of large size, growing about 100 feet high, and much resembling the P. Strobus in general appearance. 59. P. Dcvoniana, Lindley. — Also one of Hartweg's discoveries from the Ocotillo Mountains in Mexico, where it is found growing from 60 to 80 feet high. This species has long, slender leaves of a rich shining green color. 60. P. filifolia, Lindley.— Grows from 40 to 60 feet high, and is a native of Guatemala. The leaves are from 12 to 14 inches in length, and very handsome. 61. P. Gordoniana, Hartweg. — Was discovered by Hartweg on the Saddle Mountain in Mexico. It grows 7 146 THE BOOK OF EVEEGEEENS. from 60 to 80 feet high, with very long, slender, light green leaves, and, according to Gordon, " has the longest and finest foliage of any kind yet known." 62, P, Grcnvilleae, Gordon. — Is likewise one of Hartweg's discoveries, with splendid long, dark green leaves, and a very robust habit of growth. It was first detected in the same locality as the preceding, and attains about the same height. 63, P, Hartwegii, Lindley. — Is from the Campanario Mountain, in Mexico, where it was first found by Hart- weg, growing from 40 to 50 feet in height. On the Ori- zaba Mountains, however, it frequently attains the height of 100 feet. 64, P, leiophylla, Schiede. — Is a handsome, smooth- leaved pine with a regular form, and is found growing in the colder regions of Mexico, where it attains the height of from 60 to 100 feet. The wood is very hard and resinous. 65, P. Lindlcyana9 Gordon. — Is from the mountains of Mexico, growing about 50 feet in height. Leaves, rather long, stout, and of a dark green color. Although quite hardy in England, it is not so with us. 66, P. Loudoniana, Gordon. — Is one of the newer introductions from Mexico, where the trees are said to grow to an immense size. Leaves, very stout, of medium length, and quite glaucous. Cones, very large and straight, from 12 to 14 inches long, and from 3 to 4 inches in diam- eter. Seeds, very large. 67, P, macrophylla, Lindley. — A beautiful Mexican pine with dark green leaves, about 14 inches in length. The tree, however, is of only medium size, but compact and striking in its habit. Discovered by Hartweg. THE PINE SUB-FAMILY. 147 68. P. Monteznm 10. A.

According to Dr. Engelmann, in the " Transactions of the St. Louis Acad. of Science," this fine new Conifer is found on the " higher parts of the Rocky Mountains, from New Mexico to the head waters of the Columbia and Missouri Rivers, and probably further ; from the sub-alpine to the alpine districts, and with Pinus aristata reaching the highest limits of timber, occupying in Colorado a belt between the limits of 8,000 and 12,000 feet. It reaches its fullest development between 9,000 and 10,000 feet, near the head waters of the streams on both slopes of the Snowy range, constituting magnificent forests about the head of Middle Park, at Tarry-all, etc., often mixed with Abies grandis" The same author thus speaks of its size: "In its most favorable localities this species makes a stately tree 60 to 100 feet high, forming a narrow, sharply tapering spire of a rather darkish hue ; trunk perfectly straight, columnar, tapering very gradually, 1-J- to 2^ feet in diameter, branches mostly small, lower ones horizontal, upper ones ascending ; on higher altitudes it is a smaller, nearly round-topped tree, very much branched, bearing more perfect fruit than in either lower or higher elevations ; on the highest sum- mits a prostrate and almost creeping sterile shrub, just as Picea nigra is found on Mt. Washington, N". H." This species was at first taken for a form of the A. nigra, by its discoverer, Dr. Parry, but upon subsequent examina- tion it has proved to be a new species. We have raised young plants from the seed furnished us by the discoverer, and will soon be able to settle the question of its hardiness with us. Dr. Engelmann says " the wood is soft, white, not knotty or resinous, therefore much esteemed for inside and cabinet work." 11. A, firm a, Siebold <£ ZuccarinL — Syn.

Cones, 3 to 4j- inches long, from 1 to H inch in diameter, pendent, short-peduncled^ thick, deflexed, straight, cylindrical, with persistent, imbricated, downy, leathery, crenulated, dark brown scales ; bracts, long, lanceolate, or sub-rhomboidal, sharp and keeled. Seeds, wedge-shaped at the base, with broad, transverse wings, and a membranaceous shell. Cotyledons, 4 to 5. We copy from Murray the following history of this new Spruce : " This species is found from the south of Kinsu, by Sikok and Nippon, to the Kurile Islands, and may thus be assumed to extend over the whole of the empire of Japan. It grows at an elevation of from 2,000 to 4,000 feet above the level of the sea. Siebold informs us that at its southernmost limits it is probably cultivated, and not wild, except in humid valleys or on the mountain Iwaga, near Nagasaki, where it is found at about 1,800 feet above the sea." It is a lofty tree with somewhat of the habit of the Common Silver Fir, and, judging from the climate from whence it comes, we may anticipate its suc- cessful introduction into our collections. As with others of the Japanese trees, confusion has arisen in its nomencla- ture, some writers affirming that A. firma, A. bifida, and A. homolepis, are three distinct species. Murray affirms them to be but one, and suggests that the diversity may have arisen from the skill of the Japanese in altering the appearance of many plants in a manner to deceive a careful and critical botanist. In A. bifida, the leaves are bifid at the apex, but Murray states that this is frequent- ly the case with young plants of all three of the alleged species; seeds of A. bifida frequently producing young 180 THE BOOK OF EVERGREENS. plants answering the description of A. homolepis in the first year, and having leaves bifid during the second, etc. 12. A. JezocnsiS} Siebold & Zuccarini. — Syn.

(Mature cones not known.) Female aments, solitary, oblongo-cylindrical, sub-curvate; bracts, minute, rhomboidally spathul.ite, alternated from the base, acute or cuspidate, somewhat crenulated, appressed, and smaller than the scale. (Murray.) In our description of Abies Fortunii will be found the characteristics which distinguish that species from this; and as the two had been generally confounded and treat- ed as the same until Murray separated them and described the leading points of each, we take pleasure in recording his decision here. The true A. Jezoensis of Siebold and Zuccarini forms a large sized tree, and produces a smooth, soft timber, which is useful for manufacturing into house- hold utensils and is frequently employed for arrows, etc. " This tree," say Siebold and Zuccarini, " which grows wild in the Islands of Jezo and Krafto, is cultivated as a rarity in the gardens of the wealthy, at Jeddo." In Sar- gent's edition of Downing's Landscape Gardening, the author says, " Our specimens, which are small, seem quite hardy," and it is to be desired that they may prove per- manently so on a longer trial. This is the JTezo-Matsu of the Japanese, and resembles closely A. Menziesil. 13.

Alcocquiana, and found growing in the vicinity of Hakodadi, on the Island of Jesso. The only specimens seen were from 20 to 30 feet in height, but exceedingly beautiful; perhaps one of the finest of the genus. Its ultimate height is sup- posed to be about 40 or 50 feet, with very rough, pale branchlets, and longer leaves than those of A. Alcocquiana. 14. A. polila. Siebold <& Zuccarini. — Syn.

Cones, from 4 to 5 inches long, 2 inches in diameter, elliptical, rounded at both ends, solitary, terminal, with obovate, or obovate- subrhomboidal, irregularly crenulated, coriaceous, glabrous, bright chestnut-colored scales ; bracts, minute, linear-ob- tuse, entire, coriaceous, scarcely equalling in length the fourth part of the scale. Seeds, rather small, with a broad wing. (Murray). According to Murray, " Siebold informs us that he saw this superb Fir for the first time during his journey to Jeddo, in the sacred groves around the temples of Miako. The form of its cones and the entire habit of the tree forcibly recalled to his mind the Common Spruce. At Jeddo he received branches of cultivated specimens, but he thinks it should be found wild in the mountains of Ni- kao. From other accounts it appears that it forms great forests on the high mountains which stretch along the frontiers of Dewa and Mutsu, all the way to the northern coast of Nippon, and, according to Japanese reports, it is likewise to be found in the Kurile Islands. It is also found wild on the peninsula of Korai, and Siebold obtained a 182 THE BOOK OF EVERGREENS. branch of a specimen introduced from thence to Japan under the name of Tojosen Momi, which signifies ' Fir of KoraL5 " § 2.— TSUGA.— THE HEMLOCK SPRUCES. The Hemlock Spruces have been placed by Carriere in a separate genus, Tsuga. The chief distinctions upon which his separation is made are the manner in which the anther cells open, which is transversely instead of longitu- dinally, the flat, somewhat two-ranked leaves, and the soli- tary, persistent, and drooping cones. It is more convenient in the present work, as well as more in accordance with our accepted botanical authorities, to make both Tsuga and Picea sections of Abies. The characters by which authors distinguish them as genera are employed here for sections, or sub-genera, and are given on page 156. The trees of this section are all of remarkably graceful habit, and their foliage presents a more light and feathery appearance than that of either the Spruces or the Firs. The general character of the trees, as well as that of the wood, is well represented in our native Hemlock Spruce, Abies CanadensiSj which may be taken as the type of this sub-genus. 15. A. Bnmoniaiia$^Wfey. — INDIAN HEMLOCK SPRUCE. — Syn. A. dumosa, Lambert ; A. decidua, Wallich ; A. ce- droides, Griffith / Tsuga Brunoniana, Carriere. — Leaves, mostly 1 inch long, straight, linear, flat, obtuse, deflexed on the margin, obsoletely denticulate towards the apex, light green above, and very silvery glaucous below. Branches and branchlets, very numerous, drooping, and slender. Cones, 1 inch long, oval, sessile and smooth; with orbicular, sessile, persistent scales, and emarginate, wedge-shaped, very short bracteoles. Seeds, small, wedge-shaped, ferruginous, with an oblong, obtuse, shin- ing, membranaceous wing. THE PINE SUB-FAMILY. 183 A very handsome and graceful tree from Sikkam, Nepal, and Bhotan, where it attains the height of 70 or 80 feet, and is found in the former locality growing at an elevation of from 9,000 to 10,000 feet, and in the latter from 6,500 to 9,500 feet ; but although it is a native of such high al- titudes, and is quite hardy in England, its success in this country is quite indifferent. In Sargent's description, he says : " We are somewhat perplexed in making up our mind about the future condition of this charming tree as to its availability. If it succeed at all, it will certainly require a good deal of coaxing. Our own specimen has been very various. It has stood some winters well, and others, not as cold but possibly damper, seemed to have destroyed it." This has been the experience with almost all cultivators of whom we have inquired, so that its ultimate success is ex- ceedingly doubtful ; and we would therefore caution any one against undertaking its culture at the North, unless he would be willing to lose a few plants in the experiment. A few degrees further south will, we have no doubt, suit it. The Gardener's Monthly says that although Gordon may class it as " quite hardy and thus deceive American readers, it will be killed easily by 10° below freezing point, according to an American-made thermometer." We believe that, with proper protection and suitable soil, it will withstand a much lower temperature than the above. The Indian Hemlock very much resembles the Common Hemlock (A. Canadensis) in general appearance, but in the former the under side of the leaves is of an elegant silvery-white color, so that, when disturbed by the wind, they create a curious yet beautiful effect. This tree is liable to the same disparagement as the A. Menziesii, in regard to its proneness to lose its leaves. Dr. Wallich says that " the slightest shake of the branch is sufficient to detach them." We have also noticed this trouble, eveii on very young plants. 184 THE BOOK OF EVEEGEEE^S. The wood warps quite easily, and in consequence is rarely used by the natives. Loudon says " it was discov- ered by Captain Webb, and named jBrunoniana by Dr. Wallich in honor of Mr. Brown." 16. A. CanadensiS9 Michaux. — HEMLOCK SPEUCE. — Syn. Tsuga Canadensis, Carriere. — Leaves, |- of an inch long, flat, obtuse, linear, dark green above, and glaucous below. Branches, horizontal, drooping, and numerous. Cones, f of an inch long, greenish when young, changing to light brown with age, oval, with few scales ; scales, roundish- oblong, entire. Seeds, quite small, with light colored wings. The Hemlock Spruce is a native of the Northern States, extending from the Atlantic to the Pacific Ocean, and from the high mountains of North Carolina, in the South, to about the 51° ]ST. latitude, near Hudson's Bay, in the North. It is emphatically a northern tree, withstanding the exposure and cold storms better than the hot summer suns of warmer climates. A sufficient proof of this is found in the fact that it becomes much rarer in the southern lim- its, and is there only found in the cooler temperatures of the northerly sides of high mountains in the Alleghanies, etc. Throughout the southern portion of the Middle States this species is found generally along the larger streams and rivers, but according to Michaux this peculiarity is not by any means a settled rule ; for in some sections where it is mingled with the Black Spruce it occurs less frequently, as the soil is more humid. Throughout our most northern border and in the British Possessions, the Hemlock Spruce forms vast forests, stretch- ing for hundreds of miles, and is frequently unassociated with any other species, but occasionally may be found in company with the Black Spruce, White Pine, and other trees. Nuttall mentions that it was collected by Dr. Scouler on the north-west coast of America, and was also THE PINE SUB-FAMILY. 185 Fig. 23.— ABIES CANADENSIS, ONE-HALF THE NATURAL SIZE. 186 THE BOOK OF EVEKGREENS. observed by Dr. Tolmie, as far north along that coast as Milbank Sound and Stikine. It is also common in the pine forests around Vancouver, and along the high banks of the "Wahlamet and the Oregon. In favorable situations this spruce forms a tall tree of about 70 or 80 feet in height, and is frequently clothed with branches nearly to the ground ; but in the thick clumps and masses, as well as in the vast forests, it runs up a tall, clean trunk that is mostly destitute of limbs for a considerable distance. The old trees, however, are liable to a disease which causes the lower branches to gradually die away, and thereby destroy the symmetry of the tree ; but to the younger plants no objection that we are aware of can be made. The regular, conical form, tapering from a broad base evenly to a long, straight, and thrifty leading shoot, is the common shape of the tree. The long, slender branches, drooping gracefully to the ground, present so beautiful a picture, that it is in- deed difficult to surpass it, and when we compare the rich, dark green foliage of a healthy plant that is va- ried so exquisitely with the marked glaucousness of the under side of the leaves, we must admire a tree which presents such a diversity of charms. We have often lingered admiringly in the contemplation of a group of these trees, watching the play of light and shade as it in- creased or diminished through their verdure, and men- tally compared these claims on our notice with the rarer introductions from abroad ; and such meditations invaria- bly resulted in the same conclusion, that, so long as they were common, (an American term for native trees), men of more means than taste would prefer the latter class. If such will it, let them enjoy their preference, but so far as we are concerned, were we restricted to one tree, we would far rather have a fine specimen of the Hemlock Spruce, than all the Deodars and Cryptomerias ever introduced. Meehan, in his admirable little book on Ornamental THE PINE SUB-FAMILY. 187 Trees, remarks of the Hemlock : " It would not be exag- geration to pronounce this the most beautiful evergreen in cultivation. Beautiful as many of the new pines are, few approach this. It has regularity without formality, and, in any point of view, elegance and gracefulness, Its habit is frequently so erect as to approach the fastigiate ; yet the ends of its branches are as pendulous as a Babylonian Willow. Its color is not of that mournful cast so common to other PinaceaB, nor of that consumptive looking hue so connected with sickliness. Stepping between these it is suggestive of innocence and lightness, which cannot fail to attract admirers for it in whatever situation it is placed. It will make the prettiest object when grown by itself, but it is a tree that has no aversion to company." Many cultivators have an idea that it is exceedingly dif- ficult to remove, and on this account have neglected it ; but frequent practice for many years has assured us that no Conifer, taken from the nursery row or from cultivated grounds, will better sustain a removal than the one we are now describing. It is true that young plants carelessly dug in their na- tive haunts, that are most likely partially or wholly shad- ed, and unprovided with a sufficient supply of delicate fibrous roots, will almost certainly refuse to live ; but if small seedlings about one foot high be selected and care- fully taken up and removed to a light mellow piece of ground that is shaded naturally, or by artificial means, success will be the result. A great mistake is continually being made by planting the Hemlock in dry situations ; for while it cannot thrive in wet and swampy ground, it greatly prefers a rather moist, deep, loamy soil and cool location, the better if par- tially shaded. In such spots the beauty of the foliage and luxuriant growth speedily develop themselves in the high- est degree. According to Michaux, the value of the Hemlock tim- , 188 THE BOOK OF EVEKGKEEXS. her is less than that of any other American resinous tree ; but since his time the immense quantity that has been an- nually consumed over our country is a sufficient proof of its popularity for rough work. Although extremely per- ishable and coarse-grained in texture, it enters largely into the construction of our buildings, furnishing a cheap qual- ity of lumber for the unimportant portions that are pre- served from the action of the weather. It is a source of regret, however, that a tree so universally scattered over the timber sections of our country, and in such immense quantities, could not have been of better quality. A re- deeming quality, nevertheless, is contained in the bark, which is of great importance for tanning. It is asserted that although inferior to oak, a mixture of the two is much superior to either when used separately. As a screen the Hemlock Spruce is greatly admired, and as it bears the shears well, grows thriftily, is of a dark green color, and very dense, it will increase in the estima- tion of planters as its availability for this purpose be- comes more fully known. Michaux mentions a peculiarity in this species of some- times ceasing to grow at the height of 24 or 30 inches, in which state it has a conical form, and its compact, tufted branches rest upon the ground. We have observed this curious variety in our own collection, and have deemed it of sufficient importance to perpetuate. Var. liana, Lawson. — Is mentioned by Gordon in his Pinetum as " not growing more than two or three feet high, and spreading on the ground with a more tufty fo- liage." It is probably not distinct from the numerous chance sports just mentioned. Vai\ microphylla, Lindley. — The Gardener's Chronicle describes this as follows : " Messrs. Fisher & Co. raised it from seed imported from Canada, and they have found it much more hardy than Canadensis itself, it not having THE PINE SUB-FAMILY. 189 suffered in the severe winters two years ago, when so many Conifers were injured. It is an Abies of such singu- larly dwarf habit that it might almost be compared with a Heath ; leaves, very dark green, with a white streak be- neath, rough at the edge, and no bigger than those of Menziesia polifolia.^ 17. A, Douglasii, Lindley. — DOUGLAS' SPRUCE.— Syn. Tsuga Douglasii, Carriere. — Leaves, from 1 to 1-J- inches long, linear, obtuse, flat, quite entire, dark green above, silvery glaucous below. Branches, horizontal, drooping, with light brown bark. Cones, from 2 to 3 or 4 inches long, ovate-oblong, light brown; bracts, numerous at- the base ; scales, thin, smooth, entire, round, coriaceous, per- sistent; bracteoles, linear, membranaceous, twice as long as the scales, with acuminate teeth. Seeds, small, oval, with a crustaceous testa, and a short, elliptic, obtuse wing. This splendid Conifer was first discovered by Menzies in the year 1797, at Nootka Sound, during the voyage of Vancouver, and from the specimens then procured the name of Pinus taxi/olio, was given it by Lambert. This specific name, however, now belongs to a beautiful variety of it that will be mentioned hereafter. It was subse- quently found by Douglas, who determined its true char- acter, and in whose honor it has been named. Throughout northwestern America, and principally along the coast from the latitude of 43° to 52°, it consti- tutes the greater portion of the heavily wooded timber ; and according to ISTuttall it extends into the valleys of the Rocky Mountains eastward to the upper waters of the Platte and the Blue Mountains of Oregon. The size of some of these trees is immense. Douglas records their height at from 100 to 180 feet, and from 2 to 10 feet in diameter; one of these prostrate stumps at Fort George on the Columbia measured 48 feet in circumfer- ence at 3 feet from the ground, and 150 feet still remained without any branches. It is supposed that the immense 190 THE BOOK OF EVERGREENS. trees found by the explorers Lewis and Clarke were of this species, some of which actually measured 300 feet in height. According to most writers, however, they vary from 150 to 200 feet in height. As the summits of the mountains are neared, this species becomes a mere bush of only a few feet in height. Dr. Parry, who recently explored Pike's Peak and other haunts of this tree, thus alludes to it : " Abundant through the eastern mountain district, except on the higher elevations. A very sightly tree of the average height of 80 feet, with a graceful, oval outline ; the spreading branches curving upwards at the extremities." In Downing's description of the pinetum at Dropmore, he says : " The oldest and finest portion of the pinetum occupies a lawn of several acres near the house, upon which are assembled, like belles at a levee, many of those loveliest of evergreens — the Araucaria, or Pine of Chili, the Douglas Fir of California, the sacred Cedar of India, the Funebral Cypress of Japan, and many others. " Perhaps the finest tree in this scene is the Douglas Fir, (Abies Douglasii). It is 62 feet high, and has grown to this altitude in 21 years from the seed. It resembles most the Norway Spruce, as one occasionally sees the fin- est form of that tree, having that graceful, downward sweep of the branches, and feathering out quite down to the turf, but it is altogether more airy in form, and of a richer and darker green in color. At this size it is the symbol of stately elegance." Having been intimately acquainted with this tree for a number of years and observed it closely, we unhesitatingly place it upon the list of available ornamental trees, with certain restrictions ; and these are the same we have fre- quently recurred to in our remarks on other Rocky Moun- tain plants. We consider it superior in hardiness to the A. Smithiana, and much less susceptible of scorching by the action of the sun's rays, THE PINE SUB-FAMILY. 191 The beautiful specimen in the collection of the late John Evans, at Radnor, near Philadelphia, is now 25 feet or up- wards in height, makes a vigorous annual growth, and with the exception of losing a portion of its leader in an unusually severe winter a few years ago, has remained entirely uninjured. This fine specimen stands on a gentle declivity facing the south-west, and is growing in a light gravelly subsoil that has proven too dry for some others of the Coniferae. The experience of cultivators in different sections of our country has been so varied and so opposite in character as to lead those interested in the success of this tree to in- quire into this apparent contradiction ; and in every case where we have been enabled to ascertain correctly, the fault appears, not to have been in a few degrees farther north or south, but to be in reality attributable to the nat- ure of the soil and location. We therefore enjoin it upon planters to select a cool, open, porous subsoil that is not too rich, and endeavor to obtain a slight protection from the northerly winds. Sargent's views on this point so ex- actly coincide with our own, that we present them here : "Plants with us in low, damp ground, suffer occasionally in color, if not in loss of leader ; whilst those grown in the shade, or on an exposed hillside, in poor, slaty soil, succeed admirably." Nuttall remarks on the quality of the timber of this species, that it is heavy and firm, with few knots, about as yellow as that of the Yew, and not liable to warp, which is quite different from the account given of it by Dr. Parry. The latter says : " Wood of slow growth, but very indifferent, inclined to warp and crack, turning red- dish-brown in drying." Var. taxifolia, London. — Syn. Tsuga Lindleyana, Hoed. — This is a Mexican variety found on the Real del Monte Mountains at an elevation of from 8,000 to 9,000 feet. It is also occasionally met with in portions of Oregon, 192 THE BOOK OF EVERGREENS. and is perhaps the plant first discovered by Menzies. It is quite distinct from the species, being smaller in size, with longer and darker leaves, and with broader, shorter, and less pointed scales ; the bracts also more contracted. Var. fastlgiata, Knight. — Differs from the species in being more compact and conical in shape, and with ascend- ing branches. Var, Standishiana, Gordon. — In the supplement to Gordon's Pinetum, this new variety is described at some length as very distinct and desirable, having large, dark, glossy green foliage, quite silvery below, but with the habit and general outline of A. Douglasii. It originated in Standish's Nursery, at Bagshot, and is not yet intro- duced into our collections. NEW SPECIES OF HEMLOCK SPRUCE. 18, A, Mertensiana, Lindley. — CALIFORNIA^ HEMLOCK SPRUCE. — Syn. A. heterophylla, Rafinesque ; A. taxifolia, Jeffrey / Tsuga Mertensiana, Carriere. — Leaves, from |- to f- of an inch long, flat, obtuse, crowded, bright green above, slightly glaucous below. Branches and branchlets, slender, drooping, and very numerous. Cones, f of an inch long, ovate, with few, persistent, reniform, entire scales, and small, pale brown seeds, with a short ovate wing. This new species was first named and described by Bongard, the Russian botanist, who bestowed upon it the title of Pinus Mertensiana, and gave Sitka as its locality. It is found, however, in different parts of northern Cali- fornia and Oregon, constituting, according to some writ- ers, one-half the timber in the neighborhood. Its height is from 100 to 150 feet, and unlike the common Hemlock Spruce it forms a roundish-conical head ; THE PINE SUB-FAMILY. 193 it is also very dense and compact in growth, and remark- ably graceful in the arrangement of its branches. The main body of the tree is usually straight, with a gradual tapering upwards, and covered with a smoothish, thin bark. We have hopes of being able to acclimate this species, the section of country from which it comes being such as to warrant the belief that it will be hardy. In England it is represented as being " entirely hardy, and very much resembling in general appearance the Hemlock Spruce." Some late English writers have confounded it with the following species, A.. Williamsonii, but it is very distinct from this in many leading characters. Timber, white, soft, and almost devoid of turpentine. 19. A. Tsuga, Siebold <£ Zuccarini. — Syn. Pinus Tsuga, Antoine & Endlicher; Tsuga Tsuja, Murray; T: Sieboldii, Carriere. — Leaves, from 6 to 10 inches long, persistent, ap- proximated, alternate, sub-distichous, linear, emarginate, obtuse, or rarely acute, smooth, coriaceous, dark green above, with a white line on each side of the midrib below. Cones, scarcely 1 inch long, elliptic, or sub-elliptical, soli- tary, terminal, obtuse, quite persistent ; with coriaceous, imbricated, pale brown scales; bracts, truncate, rather broad, irregularly bifid, closely appressed. Seeds, small, ovato-rhomboidal, somewhat compressed, with a pale, fer- ruginous, membranaceous wing. A small Spruce, rarely exceeding 20 or 30 feet in height, and reminding one of a small Hemlock Spruce, both in habit and general outline, and in fact they are nearly allied. There also exists a close relation between it and A. Brunoniana. It has a very erect trunk, with a dark brown bark, and numerous, pale, slender branchlets. This new Spruce is found in the northern provinces of Japan, in the mountainous parts of Mutsu and Dewa, but is quite rare ; Siebold only noticing it in the gardens and shrubberies surrounding the temples. The wood is yellow- 9 194 THE BOOK OF EVERGREENS. ish-brown, and is manufactured into various household utensils. Var. UJilia, Siebold. — Has much smaller leaves than the species and does not exceed 2 or 3 feet in height, and is frequently grown in pots by the Japanese. 20. Ai Hookeriana? Murray. — HOOKER'S HEMLOCK SPRUCE. — Syn. A. "William sonii, Newberry; Abies Merten- siana, English authors / Picea Williamsonii, JEngelmann. — A tree of large size and alpine habit; leaves, short, acute, compressed, with a lenticular section. Cones, pendent, long, ovoid, acute, \\ inches long, purple when young ; when old, cylindrical or somewhat conical, with a flattened base ; scales, rounded, entire, large in old cones, strongly reflexed, except at the base of the cones ; seeds, small, ovoid, black ; wing entire, elliptical, pellucid ; male flowers, in small, nearly spheroidal heads. (Hfewberry.) From the Cascade Mountains, Oregon. Lawson, in his new work on the Conifera?, considers this and A. 'Williamsonii the same, and gives his reasons at some length. We take great pleasure in recommending this rare and new Conifer to the notice of cultivators, believing, as it comes from the same section of country as many others of our hardy plants, it will most likely prore a success. According to Dr. Newberry, it is an alpine species, grow- ing near the region of perpetual snow, and one of the finest of the genus. It has an irregular, spreading, and re- markably graceful habit. 21. A, Albertiana, Murray. — Syn. A. Bridgei, Kellogg. — This was described in the Proceedings of the Acad. of N"at. Sci. of California by Kellogg, but Murray's name has the priority by some two years. From Fort Lang- ley, arrtl closely allied to A. Canadensis. A tree 80 to 100 feet in height, of dark verdure and graceful appear- ance; the branchlets are very hairy, slender, and droop- ing. Abundant on both north and south bank of Fraser THE PINE SUB-FAMILY. 195 River. The timber is firmer, finer, and straigliter-grained than the Canadian Hemlock Spruce, which it represents on the Pacific Coast. The fruit is remarkably abundant ; a specimen 8 inches long had 60 cones. § ».— MCEA.— FIR. The Firs are found in Europe, Asia, and North Ameri- ca, extending from the torrid to the frigid zone, but greatly preponderating in the latter. Some of the finest specimens are found on our north-west coast, and are rep- resented by travellers as being of enormous proportions. A. bracteata, A. nobilis, A. amdbilis, and A. grandis, are all magnificent trees, averaging from 150 to 200 feet in height. Mexico is well represented by A. religiosa, an elegant Conifer growing 150 feet high ; and Europe, al- though possessing no such gigantic species, furnishes A. Nordmanniana, A. pectinate^ and A. Pindrow, which are often found 100 feet high or over. The Firs are remarkable for a perfect and formal, coni- cal growth, furnished with branches to the ground, and terminating at the apex in a straight, strong, leading shoot ; thus whilst they present a form perfect in its out- line, rich in color, and vigorous in growth, it must be con- fessed is by no means so graceful as the Spruce, or so charming as the Pine. On hills, rocky prominences, or rugged valleys, where a picturesque effect is to be intro- duced, they are of the greatest importance; but on smooth, plain lawns, or tame, highly cultivated landscapes, they should be very sparingly and judiciously introduced. The timber of most of the species is of but secondary importance, but the resinous products of the greater por- tion are very abundant and valuable. In the classifica- 196 THE BOOK OF EVERGREENS. tion of this sub-genus we have adopted the plan pursued by Endlicher and Gordon, of dividing it into two distinct groups, viz. : Bracteata, and Brevibracteata / the former with the bracts projecting beyond the scales, and the lat- ter having them enclosed or shorter than the scales. GROUP 1.— KRACTJEATA. 22 1 A, Apollinis, Link. — APOLLO SILVER FIR. — Syn. Picea Apollinis, Hauch / A. Reginae Amaliae, Heldreich, etc. — Leaves, from ^ to 1 inch in length, linear, flat and obtuse, or lanceolate and acute, larger leaves slightly glau- cous beneath, smaller ones quite glaucous below, the former on the adult branches very numerous, whilst the latter on the young branchlets are more scattered and much narrow- er. Male catkins in groups, surrounding the summits of the adult, sessile shoots. Cones, axillary, solitary, erect, very resinous on the surface, and similar to those of A. CepTialonica in size and shape ; scales, 1 inch or more wide, incurved, and rounded on the upper margin ; bracts projecting beyond the scales, ear-shaped, flat, reflexed, mucro'nate, and lacerated laterally on the edges, and with a long, central, reflected point. (Extracted from Gordon's description.) This Silver Fir, which was described by Gordon in his first edition of the Pinetum, as a synonym of Picea Cepha,- lonica, has been in his supplement to the work assigned to the position of a species, but we are fearful, without suffi- cient grounds. The fructification, which is usually the most unerring guide in determining these questions, is so nearly alike in the two, as to be scarcely distinguishable, if at all ; and in young plants that have fallen under our own ob- servation, no distinction could be perceived. As the plants increase in age and present a more mature aspect, the case may be different, and the differences be- THE PINE SUB-FAMILY. 197 come more apparent ; we therefore yield to the judgment of such authorities as Link, Antoine, and Rauch, and like Gordon have given it a specific description, although sub- sequent observation may cause us to diifer from them. It is a native of Greece, where it is found growing on the mountains at different elevations, from 1,500 to 4,000 feet, and forming a tree from 60 to 70 feet in height. Young plants in our grounds have proven hardy, and as they resemble A.. Ceplialonica, are equally handsome. We feel no hesitation in recommending it for trial. 23, A, Imlsamea, Marshall. — BALSAM FIR, OR BALM OF GILEAD FIR. — Syn. Picea balsamea, London. — Leaves, from f to 1 inch long, narrowly linear, spreading, slightly recurved, flat, dark green above, and silvery glaucous be- neath. Branches, horizontal and numerous, with a smooth bark, abounding in resinous vesicles. Cones, 3 to 4 inches long, cylindrical, violet colored ; scales, broad, thin, round- ed, smooth; and obovate, mucronate, serrulate bracts. Seeds, small and angular. The Balsam Fir was first described by Humphry Marshall, the pioneer in American botanical authorship, in his work entitled Arbustum Americanum. The habitat of this species, according to Gray, is in cold, damp woods and swamps, New England to Pennsylvania, Wis- consin and northward. It is also a native of Canada, Nova Scotia, etc., where it is very abundant. This Fir has been frequently confounded with the A. Fraseri, especially as the description given by Michaux of A. balsamifera belongs to A. Fraseri. The two are quite distinct in their cones, and especially so in the bracts, but otherwise are much alike. The Balsam Fir generally grows about 30 or 40 feet in height, and forms, when young, a compact, conical tree of regular outline and rapid growth. It has been so long a popular ornamental tree in many parts of this country, that it appears like turning our backs upon an old friend 198 THE BOOK OF EVERGREENS. Fig. 24. — ABIES BALSAMEA, TWO-THIRDS THE NATURAL SIZE. THE PINE SUB-FAMILY. 199 to denounce it; but there are so many better species to substitute in its place, that we can part with it without regret. For the first few years it is a model of beauty in color and form, but as it nears maturity, and often before, the lower limbs commence to decay, and thus the beauty and symmetry of the tree are forever destroyed. Not withstanding all that has been said upon the subject, and the advice from all well-intentioned dealers who are aware of its peculiarities, together with facts staring them everywhere in the face, a large majority of purchasers re- quest this tree of the nurseryman in advance of any other, and so long as there is a demand, it will continue to be grown. We have always been sorry that the late A. J. Downing commended it so highly in his Landscape Gar- dening. A very aromatic liquid resin is obtained from this tree by incisions made in the bark, and is called, very incor- rectly, " Balm of Gilead," the name " Canada Balsam " be- ing much more appropriate. The wood is light, yellowish, and slightly resinous. This species was introduced into England as early as the year 1697, by Bishop Compton. Var. longifolia, Booth. — " Has leaves longer than the sheaths, with the branches somewhat more upright. — (Loudon.} Var. variegata, Knight. — Has yellowish leaves inter- mixed with the usual color ; otherwise as the species. 24. A. bracteata^-Hbo&er. — LEAFY-BRACTED SILVER FIR. — Syn. Picea bracteata, Loudon. — Leaves, 2 to 3 inches long, linear, entire, crowded in two rows, flat, coriaceous, rigid, light shining green above, silvery glaucous below. Branches, in whorls, spreading, slender ; lower ones, de- cumbent. Cones, 4 inches long, 2 inches in diameter, ovate, on short peduncles, turgid, solitary, lateral, with roundish, reniform, concave, crenulate, acute, persistent scales ; bracts, wedge-shaped, rigid, coriaceous, trilobed at apex, lateral lobes irregularly dentate, short and round- 200 THE BOOK OF EVERGREENS. ish, middle segment 2 inches long and recurved, varying but little from ordinary leaves. Seeds, oblong, wedge- shaped, tetragonal, with a grayish-brown testa, and very short, thinly membranaceous, flat, reticulated, entire wings. This species was discovered by Douglas in Oregon growing on the higher mountains, and was afterward found by Dr. Coulter on the sea-side mountain range of Santa Lucia, in latitude 36°, and according to his authority is about 120 feet in height and 2 feet in diameter, with a trunk as straight as an arrow. The very curious and remarkable cones borne by this tree are handsomely fringed by long, leaf-like bracts, that are entirely different from those belonging to any other species. The foliage is quite long and of a beautiful bright green color, which finely contrasts with the glau- cousness of the under side, and the whole form of the tree is unexceptionable. Frequently but one-third of the body is clothed with branches. Douglas, in his description of the species, remarks : " When on the tree, being in great clusters, and at a great height withal, the cones resemble the inflorescence of a jBanksia, a name I should like to give this species, but that there is a P. Bariksii already. This tree attains a great size and height, and is on the whole a most beautiful object. It is never seen at a much lower elevation than 6,000 feet above the level of the sea, in lat. 36°, where it is not common." knowing of any specimen of the A. bracteata in cultivation in this country, we are of course unable to speak of its adaptation to our climate ; but Gordon says in England : " It is quite hardy, but suffers very much in its young growth from late spring frosts." If that indi- cates a quite hardy tree, then we greatly mistake the meaning of the term ; as to its succeeding with us, we have our doubts, however we may desire it to do so.
