WHEN this revised Edition was commenced, it was contemplated — with the aid of kind Friends — to insert a brief description of all the indigenous species of the Vegetable Kingdom which had been detected in our County, — together with such introduced plants as had become naturalized, or were CULTIVATED for useful purposes. It soon became apparent, however, that the lower Orders (especially the Fungi) were so multitudinous, as well as obscure, that it would require more time to accomplish the undertaking, than /, at least, had any right to reckon upon. It was found, also, that to include the whole, would render the work inconveniently voluminous. A descriptive enumeration of the Fungi, alone, would make a respect- able volume. It was therefore concluded to omit all below the Lichens, — and leave that portion of our Botany to the future enter- prise of our Chester County Naturalists. For the account of our Mosses and Hepaticae, I am indebted to the researches, and kind attention, of THOMAS P. JAMES, Esq. an enthusiastic Bryologist of Philadelphia. The Lichens have been collected and determined by Dr. EZRA MICHENER, of this County, — a Naturalist from whose acumen, diligence, and indomitable per- severance, we may fairly expect as thorough an exploration of every department of our Cryptogamy, as the active duties of his Profes- sion, and the life-time of an Individual, will permit. I am gratified, moreover, in knowing that a few zealous and faithful Lovers of Nature are engaged with him, as Collaborators, in the laudable attempt to prepare a comprehensive Natural History of the County of Chester. — w. D. PRELIMINARY DISCOURSES. DISCOUBSB I. Definition of Botany. Inducements to the Study. HAVING prepared a new Edition of the Chester County Flora, — partly for the purpose of including those plants "which have been detected in the County since the preceding one was published — but chiefly for the sake of presenting the work in a form somewhat less diffuse in its details, as well as more congenial in its arrangement with the present state of the Science, — I thought it might be accept- able to the youthful Cultivators of Botany, in our venerable Baili- wick, to premise some general observations touching the subject to which the volume is devoted. This I propose to do, in a few brief and familiar Discourses ; such, in substance, as I have been in the habit of employing, orally, when aiding the researches of the Pupils in some of the West-Chester Seminaries. As in all attempts to impart or acquire information, it is most advantageous and satisfactory to begin at the beginning, — we may as well commence by a definition of the Science, to which we propose to direct our attention. It derives its name from the Greek word Botdne — meaning an Herb, — and may be briefly defined as "the natural history of the Vegetable Kingdom ;" or, to be somewhat more explicit, it is that Science which has for its object a knowledge of the structure, functions, and characters of Plants — together with a just comprehension of those general affinities, and peculiar features, by which they may be grouped into kindred families, — and yet be distinguishable, among themselves, into well-marked Genera, and Species. A very natural preliminary inquiry, on the part of a Pupil engaging in the study of Botany — or, indeed, in any other study — would be respecting the utility, or value, of such an attainment; and therefore — in order to encourage the young Beginner — it may be well to hint at some of the inducements to the undertaking. These may be considered in reference to mental discipline, intel- lectual gratification, and practical usefulness. It is impossible for 5 Vi PRELIMINARY DISCOURSES. any one, endowed with the common attributes of humanity, to avoid being something of a Naturalist. One of the earliest indica- tions of Intellect, consists in the perception, and discrimination, of the beings and objects subjected to its cognizance. In proportion as the mind is expanded, and its faculties disciplined, so are its powers of discrimination augmented. Natural Science — or that knowledge which enables us to ascertain, to distinguish, and to arrange, or classify created beings — is emphatically a science of observation; and no study has a happier tendency to induce habits of attention, and accuracy in noticing the characteristic features of objects. No one is less likely to be misled by vulgar prejudices, or to be made the dupe of imposture, than the careful observer, and intelligent student, of Nature. Habitual scrutiny renders him acute in detecting error, and discovering truth, — while it makes him cautious in receiving marvellous statements unsupported by credible testimony. While his faculties are thus improved by a salutary discipline, his taste is no less gratified by the pleasures of the study : — and, of all the inanimate products of creation, there is none more agreeable to contemplate, than those which constitute the Vegetable Kingdom. Destined, by the wisdom of a bountiful Providence, for the susten- ance of a higher order of creatures, — they have, at the same time, teen admirably adapted to the purpose of adorning the surface of the earth, and charging with fragrance the atmosphere which surrounds it. Occupying an intermediate position, between minerals and animals, they afford us the means of investigating the wonders of organic life, without the infliction of torture, or the necessity of witnessing the sufferings which attend such researches in sensitive beings. Hence, the study of the vegetable creation has ever been a favorite pursuit with gentle minds. There is a calm delight in the contemplation of Plants and Flowers, which is never felt — and can never be appreciated — by those who find their chief gratification in the turmoils and commotions of the animal world. The disposition of man derives much of its character from association, and external impressions; and it is, doubtless, partly owing to the bland in- fluences of a rural life, that enlightened agricultural communities are less prone to those cruel excesses, which so often disturb the arti- ficial and struggling society of crowded cities. If such be the tranquilizing tendency of a simple residence among the Vegetable tribes, — how propitious to the growth of the gentler virtues must be the pursuits of the Botanist, who may be said — almost without a figure— to hold daily converse with some of the loveliest works of PEELIMIHAEY DISCOUESES. VU the Creator, — and to regard with something like the pleasure of a friendly recognition, every Plant -which he has successfully in- vestigated!* We know, indeed, that those groveling mortals who consider nothing as valuable, but mere tangible wealth, are apt to regard the researches of the Naturalist as useless and frivolous,— just as gross, uncultivated minds suppose all pleasures to consist in sensual grati- fications, and have no conception of such a thing as intellectual enjoyment. It is the besetting infirmity of sordid natures, to mis- take the instrument for the object ; to limit the aim, and confine the affections, to the means of enhancing our character, as rational beings — instead of employing those means for the attainment of a nobler end. But, is it true, that the studies of the Naturalist are useless and frivolous ? On the contrary, the most bigoted Utilitarian — on a moment's reflection — will be forced to admit, that they are fraught with results of daily, and high practical value, in many of the most important pursuits. To the Agriculturist, the Gardener, the Physician, and the Artist, a correct — and even scientific — knowledge of the Vegetable Kingdom is, to a certain extent, indis- pensable : — for, a scientific knowledge of plants merely implies an acquaintance with their true character and properties, — and that, every person whose business is with plants, is bound in honesty and good faith — as well as by the requirements of self-interest — to possess. Such knowledge is, of course, to be best obtained by means of the most skillful, systematic, and facile method of in- vestigation; or, in other words, by the help of a truly scientific arrangement. * No one ever heard a true lover of Botany complain of taedium vitae, or of a want of pleasant employment for his leisure hours. His pursuits, it is true, do not produce that vehement excitement which attends the scrambling rivalry of political aspirants, and is so seductive to the eager fancies of the crafty and ambi- tious ; but the gratifications resulting from their culture — being founded on a consciousness of their value to our fellow creatures, as well as to ourselves — are of the most precious and enduring character,— and are, moreover, wholly inde- pendent of vulgar taste or caprice. [See Sir H. DAVY'S Consolations in Travel.] The attractions of Botanical Science are truthfully and appropriately alluded to, in the following extract of a Letter from the late Sir JAMES EDWARD SMITH to the Rev. Dr. MUHLENBERG,— dated London, March 6, 1793 :— " You cannot be more enthusiastically fond of Botany than I am; and your letter promises me a fresh instance, in addition to many already experienced, that this study— charming in itself— is still more valuable as a key to the intercourse of the most amiable minds. To Botany I owe friendships and connexions I else could have had no chance of forming; and your Letter, overflowing with the milk of human kind- ness, and with the amiable modesty of real merit, promises mo one which it will be my most anxious care and ambition to deserve." Viii PRELIMINARY DISCOURSES. The successful culture of Vegetable Products, requires a know- ledge of the character and habits of the Plants which yield them ; and that knowledge — so far as it is possessed and applied — is neither more nor less than practical Botany. He who is acquainted with the greatest number, and best understands how to multiply the most valuable, is at once the best Botanist, and the most accom- plished Agriculturist and Gardener. Is it not desirable, then, that we should extend our knowledge of the useful Plants, — and learn to estimate correctly, their true and relative values ? Is it not necessary, also, that we should have a competent knowledge of the pernicious and worthless Plants ? But, to accomplish this, is to make a respectable progress in the Science of Botany. Hence I contend, that a certain portion of Botanical knowledge is indispensable to the Farmer who aspires to excellence in his profession, — and who would aid in elevating that profession to the rank which it is intitled to hold, among human pursuits. — It is not necessary that he should prosecute the study in all its extent ; for that would be the business of a life-time : But he ought to make himself acquainted with the Vegetation of the region, or district, in which he resides,— and he should understand well the character of all those plants which immediately concern him, as an Agriculturist. This is a duty by no means so difficult as is generally supposed: And with the aid now afforded by elementary and systematic writers on the subject, the attainment is rendered as agreeably interesting, to an intelligent mind, as it is profitable in its practical -results. The man who does not know the more im- portant plants by which he is surrounded — whose eye has not learnt to discriminate their characters, — is deficient in one of the primary qualifications of an enlightened cultivator of the •soil. In truth, it is mortifying to see a good practical Farmer, or Gardener, ignorant of some of the very plants which it most behoves him to know, — wasting his time, and his energies, in mis-directed ^efforts to protect himself from the vegetable pests which invade his grounds. Many of our farms are already over-run with worthless weeds, which are extremely difficult to subdue; -and we are menaced with the inroads of others still more annoying and pernicious : Yet there are but few of our Agriculturists who fire able to identify these invaders, when they make their appearance, — or who seem to be aware of the importance of prompt and vigorous measures for their extirpation.* * I have seen an excellent old Farmer zealously waging war upon the fetid Chamomile (Maruta. Cotula, DC.), under the mistaken belief that he was contend- ing against that troublesome nuisance, the Ox-eye Daisy (Leucanthemum, vulgare, Lam). Some years since, a distinguished agricultural gentleman published a PRELIMINARY DISCOURSES. IX This ought not to be the case, among a people invested with the lofty privileges which we enjoy. The rising generation, at least, should be taught to notice what they see, — to observe, to think, and to discriminate. Our young Farmers should learn to cultivate their minds, as carefully as they do their acres; and not be permitted to grow up in the neglect of their noblest faculties, — nor — as a modern writer expresses it — be content "to wander among the productions of Nature, with little more perception, or enjoyment of her charms, than a cow on a common, or a goose on a green." It is not unusual to hear persons say, that they should really like very much to cultivate an acquaintance with the Natural Sciences — and especially Botany, — if they only had time for such pursuits. — I beg leave to suggest to these worthy people, that they have mis- apprehended the true nature of their complaint, — and that they not only deceive, but really flatter themselves, by relying upon such an excuse. It is not so much the want of time, which afflicts them, as it is the want of taste, and the neglect of opportunities. Most people contrive to find time for what they earnestly desire to do ; and if driven to the necessity, are apt to take it, at any rate, for those pursuits which they are resolved upon. But the fact is, we all idle away countless hours of our existence — especially in the morning of life — which might be successfully devoted to the attain- ment of useful knowledge* It is true, indeed, that the higher intellectual enjoyments, afforded by "the amiable Science," can only be fully understood by those who are blest with a lively sense of the Beautiful, in Nature. Its purest delights necessarily inure to votaries of that description ; for, according to the proverbial philosophy of honest SANCHO PANZA — " No es la miel para la boca del asno:" Yet it is no less true, that taste is a faculty which can be cultivated ; and opportunities to be improved, happen to all. Some of the most enthusiastic and suc- cessful students of Nature that I have ever known, prosecuted their inquiries under a constant pressure of the every-day cares and duties of life ; and yet were remarkable for the exemplary perform- ance of those duties. •{• series of essays, for the purpose of rousing the farmers to a simultaneous attack •upon what he supposed to be the Canada Thistle, It was soon discovered, how- ever, that the plant which he had in view, was the comparatively harmless Dipsacus sylvestris, Mill, or Wild Teasel : and yet the real Canada Thistle (Cirrium arvense, Scop.) was then actually introduced, and spreading around him, tmre« cognized and unknown, either by himself or his neighbors J f " Alas for us, when we become so sunk in utilitarian toil as to be blind to the beauty with which even common cares are daily wreathed ! "— Miaa MABGARET FULLER. «^» ak, ectin u PRELIMINARY DISCOURSES. , In reflecting upon the interesting character of Botanical know- ledge, and upon the many inducements to acquire it, — one i3 naturally led to ask, why a rational acquaintance with the Vegeta- ble Products which every where surround us, and are literally strewed along our paths, should not be adequately inculcated in all our Seminaries, — and especially I would ask, why such a humaniz- ing and elegant Science should not be made an indispensable branch of Female Education. As a mere accomplishment, it is intitled to rank with any of those ornamental acquirements to which so much time is devoted. As a means of enlarging the views, and disciplin- ing the mind — training it to habits of correct observation, and profitable reflection, — the Study of Plants is far superior to many of the fashionable and fugitive attainments, which so generally engross the attention of young Ladies. It is a pursuit, too, which carries with it its own reward. The knowledge which it affords, is at once pleasing in the acquisition, and of enduring value. It is continually called for, and always at command, — ready to minister to the instruction and gratification of the possessor — whether in the Garden, the Field, or the Forest. These Studies — said the Roman Orator, on another occasion — and the averment is no less applicable here, — these Studies are the intel- lectual nourishment of youth, and the cheering recreation 0jf age ; they adorn prosperity, and are the refuge and solace of adversity ; they are pleasant at home, and are no incumbrance abroad; they abide with us by night — go with us in all our travels — and lend additional charms to the attractions of our rural retreats.* Those who make only occasional visits, or excursions, in the country, will find their pleasure greatly enhanced by an acquaint- ance with the Plants which mainly contribute to the charms of the scenery: But, by those whose constant residence is in the midst of the vegetable tribes, a reasonable knowledge of Botany should be regarded — not merely as an accomplishment, but — as one of the indispensable qualifications for the duties of rural life.f I have > * Ilaec Studia adolescentiam alunt, senectutem oblectant, secundas res ornant, adversis perfugium ac solatium praebent; delectant domi, non impediunt foris ; pernoctant nobiscum, peregrinantur, rusticantur. — CICERO, pro ARCHIA Poeta. f " Si vous avez vraiment 1'amour de la Botanique, vous ne traversez pas une prairie, YOUS ne suivez pas la haie d'un chemin sans etre en communication in- time, je dirai presque en conversation avec les plantes qui sont autour de TOUS ; vous les saluez du regard, si vous les connaissez, — sinon vous vous arretez aus- sitot et les interrogez avec empressement et plaisir; et si vous voyagez, quel interet profond et toujours nouveau s'attache a vos promenades ; comme vous vous trouvez heureux en comparant votre ardeur a 1'air d'indifference et d'ennui du promeueur oisif ou du touriste blase!

PBELIMINABY DI8COFB8ES. already intimated the opinion, that an American Farmer should blush to be ignorant of the objects of his peculiar care ; and I know not why a Farmer's Wife, or Daughter, should be entirely excused for a like deficiency. On the contrary, I am of opinion that it is to Wives and Daughters we must look, for the commencement of a salutary reformation in intellectual pursuits and discipline. The work must begin at that early period of life, when the character is being moulded under female auspices and care. The knowledge here advocated, is unquestionably desirable for both sexes ; and I sincerely believe, that the most effectual method for diffusing it, will be — first properly to educate, and then — to invoke the co-opera- tion of the Ladies. Their potent influence has been felt, and owned, in many a noble cause ; and I cannot permit myself to doubt its controlling eificacy in this. DISCOUESE II. Definition of the Vegetable Kingdom. IN this Discourse, it is proposed to define what is meant by the terms, Vegetable Kingdom, — and to notice those characters by which a Plant is known, and distinguished from the other objects in nature. The material world has been arranged, by the generality of Naturalists, in three great divisions, — which they have denominated the Mineral, the Vegetable, and the Animal Kingdoms. These three Kingdoms are, for the most part, readily distinguishable by the jnost superficial observer; yet, so nearly do the tribes, on the con- fines of the divisions, approach each other in structure and character, that it is by no means easy, with descriptive phrases, or definitions, to draw a satisfactory and unexceptionable line of demarcation between them. We have no difficulty, indeed, in distinguishing an Ox from an Oak tree — nor a cabbage from a boulder of granite : But, when we descend to those humbler existences, called Zoophytes, and Corallines, we are sometimes puzzled to determine which is Animal, and which is Vegetable. Some of the lower orders of Plants, too, (such as a portion of the Fungi, and Lichens,) are often so simple in their structure, that they seem to be formed by a process somewhat analogous to that of crystallization, — and therein are approximated to the Mineral kingdom. xii PRELIMINARY DISCOURSES. Various attempts have been made, by Naturalists, to designate the distinguishing characters of the three great divisions. The celebrated LINNAEUS, with his characteristic point, and brevity, defined them thus: Stones (said he) grow; Vegetables grow, and live; Animals grow, live, and feel.* It would be difficult, if not impracticable, to giv« a better definition in the same number of words : But the description furnished by Prof. DE CANDOLLE, will probably be considered as more complete and satisfactory, -j- The bodies existing in nature— says the distinguished and lament- ed Professor of Geneva — may be ranked under two great divisions : — I. INORGANIC BODIES, — or those which are rude, homogeneous in their structure, destitute of life, and growing only by the mere addition of similar particles to their exterior surface. II. ORGANIC BODIES, — composed of heterogeneous parts, endowed with life, and growing by the introduction of dissimilar particles within the intimate tissue, or vessels of which those parts are formed. Inorganic bodies may be considered as of two kinds : Some of them of immense magnitude, sphaeroidal in their figure, and distributed through space, — constituting what are called Stars, or heavenly bodies ; the others, comparatively small, situated on our globe, and all tending more or less to the crystalline form, — being known under the general name of Minerals. Organic bodies are also of two kinds: the one destitute of sensation, of voluntary motion, and of a stomach, — namely, Vegetables; the other, endowed with sensation, capable of voluntary motion, and furnished with an internal sac, called a stomach, — these are Animals. The foregoing classification may be recapitulated thus : I. INORGANIC BODIES — dead, homogeneous, growing by juxta- position : two kinds, — 1. One kind, celestial and sphaeroidal — Stars. 2. The other, terrestrial and crystallizable — Minerals. * The following are the words used by him, whom PULTENEY designates as the "high priest" of the Science -.—Lapides crescunt; Vtgetabilia, crescunt, etvivunt; Animalia crescunt, vivunt, et sentiunt. f The following, from AUGUSTS DE ST. HILAIRE, .presents, neatly and briefly, the distinction between inorganic and organic bodies. " Parmi les corps qui nous environnent, les uns, bruts et inertes, sont prives de mouvement et de vie; ils ne naissent point, ils se formcnt; ils ne se nourrissent pas, Us s'agglomerent : ils ne meurent point, ils se decomposent. Les autres, au contraires, naissent pourrus d'organes destines a des fonctions diyerses ; ils vivent,se nourrissent, se deyeloppent, et, avant de se decomposer, ils meurent. Les premiers sont les corps inorganiques» les seconds lea corps organises."— Morphologic Vegetalc, PRELIMINARY DISCOURSES. XiU II. ORGANIC BODIES — living, heterogeneous, growing by intus- susception ; two kinds, — 1. One kind, destitute of sensation, of voluntary! yegetdbles motion, and of a stomach. / 2. The other, endowed with sensation, capable of \A- ^ voluntary motion, and provided with a stomach. / Certain Naturalists have been so forcibly impressed by the con- templation of the gradual and near approach of the two great divisions of organized beings, that they have thought we should admit of but a single class, — which they have designated* by the name of the organic kingdom:. Others, again, have proposed to establish an intermediate kingdom, between animals and vegetables, to consist of Zoophytes, Sea-weeds, and Mushrooms. Both pro- positions, however, have been rejected by the generality of Natural- ists, with great unanimity. On this head, and in further illustration of the subject, the eminent Author here cited remarks — that those being& which seem to us to be intermediate between animals and plants, ought rather to be considered as evidences of our ignorance, than as proofs of the existence of a peculiar class-; and although it may be correct to Bay, that the two organic kingdoms havfrsuch striking resemblances, and approximate so nearly, that a satisfactory line of demarcation cannot be drawn, they nevertheless present differences of such a character that it is useful to separate them, — seeing that these dif- ferences exert an influence upon the progress of the study, in the two kingdoms, and consequently upon the logic of the two Sciences. Assuming as a fact — or as an extremely probable hypothesis — that Animals are endowed with sensibility, and that Vegetables are destitute of it, we shall see resulting from that supposition, nearly all the differences that we observe between animals and plants ; be- tween Zoology and Botany. Since Animals have a consciousness of their existence, and a sensation of pain and pleasure, it is natural to suppose that they should endeavor to avoid the former sensation, and seek the latter, — that is to say, that they should be endowed with the faculty of voluntary motion ; for, if we supposed them destitute of this faculty, we should have no means of ascertaining their sensibility. Plants, on the contrary, can perform no other motions than those which are produced by external agents, or by certain mechanical circum- stances of their structure. These motions can be neither voluntary, nor truly locomotive. XiV PRELIMINABY DISCOURSES. An Animal, endowed with sensibility and the power of motion, can select the food necessary for his subsistence, — and go in quest of it, when he does not find it in his immediate vicinity; and can seize it, in order to appropriate it to himself. He can, consequently, nourish himself with various kinds of matter, — even with kinds which are but partially distributed in nature — being such as are already organized. A Plant, on the contrary, being unable to distinguish what is proper for its sustenance, or to seize any kind of prey, must neces- sarily nourish itself with matters which are so generally diffused over the globe as to be found almost every where ; which are suf- ficiently inert to oppose no resistance to the feeble means of absorp- tion with which it is provided, — and sufficiently soft and yielding to require no mechanical division. Consequently, there are none but inorganic substances — such as water, air, and matters which are soluble in those two vehicles — adapted to that purpose ; and these are, in fact, the substances which serve for the nutrition of plants. Animals, then, can select for their nourishment, a great variety of matter, — and consequently, the organs of their nutrition must present a corresponding diversity : Vegetables, on the other hand, are nearly all subsisted on the same materials, — and therefore, their organs of nutrition are very nearly similar. Animals, which select their food, often experience intervals in which they are unable to procure such as is suitable for them ; and when they do find it, they lay in a provision to last them for a time. It is necessary, then, that they should be furnished with a receptacle in which to deposit their store of nourishment: thia receptacle is called the stomach. Plants, being constantly surrounded by their appropriate aliment, and never changing their position, have no necessity to lay in a stock of provisions, — and accordingly have no stomach in which to receive it. The nourishment of Animals being deposited in an internal cavity, all the vessels of the animal are found converging toward that centre : But in Plants, the absorbing vessels are directed toward the surface. Animals, says BOERHAAVE, are nourished by internal roots, — and Plants by external roots : Consequently, the structure of vegetables will be calculated to multiply surfaces, — and will be perfect in proportion as it is fitted to accomplish that object. The organic structure of animals, having a central tendency, will be perfect in proportion to the perfection of their internal organization. Inasmuch as the essential seat of nutrition, in Animals, is placed in the interior — and as the vessels are all directed toward and about that centre,— those vessels must continue to perform the same PRELIMINARY DISCOURSES. XV office, during the existence of the animal: But the vessels of Plants being directed to the exterior, there will be a constant possibility, either of their being elongated, or of new ones being developed on the outer surface. There will then, consequently, be a certain limit to the growth of Animals; but none to that of Vegetables. There will then, in Animals, be a death from old age ; which will happen when the existing vessels — not being capable of renovation — shall be obstructed by the influx and lodgment of the minute particles of matter which are conveyed to them. This cause of death does not occur in Vegetables — at least, not in perennial vegetables, — since new vessels may be indefinitely developed, and take upon them- selves the office of the old ones. Animals, therefore, die of old age, or of accidents ; perennial Plants of accide'nts, only. In consequence of Animals having a centre of nutrition, and of life, it follows that they can rarely, if ever, be divisible into several individuals ; for those animals called Polypi — which seem to be an exception to this rule — ought rather to be considered as aggrega- tions of a number of individuals : Plants, on the contrary, having no common centre — and being endowed with the faculty of pro- ducing new vessels to an indefinite extent — may be divided without loss of life, and can be indefinitely multiplied by cuttings.* From the general considerations thus presented, the following Principles seem to result : — 1. That the differences between the two organized kingdoms consist essentially in this, — that one of them is endowed with sensi- bility, and the power of voluntary motion, of which the other is destitute. 2. That the general office, or business of Plants — in the great system of a wise and beneficent Providence — is to elaborate and prepare inorganic matter, so that it may become fitted for the nourishment of Animals :f and * This is more particularly true, however, in those plants which form buds, and live more than a single season; for the buds of trees, and shrubs, may be regard- ed as so many distinct Individuals, congregated on a common stock. Even those perennials with herbaceous stems, which die down to the ground every winter, form a kind of buds in the crown of the root (or rhizomd), from which proceed the aerial stems of the ensuing summer. Those plants called annuals (which germinate from the seed, bloom and perfect their fruit, and die, as it were a natural death, within the year) rarely produce anything like buds : and are by no means so susceptible of division, or multiplication by cuttings, as the woody perennialt. t"It is one of the laws of nature that Animals shall feed on organized matter, and Vegetables on unorganized. For the support of animal life, therefore, we require vegetables to change the mineral constituents of the surrounding media Into suitable nutriment."— Prof. HA&VIY. XVl PBELIMINABY DISCOUBSES. 3. That in the study of those two kingdoms, we should never lose sight of the essential characters which distinguish them ; and should extend the application of the principles, which are peculiar to each, with great caution, — lest we be misled by a false analogy. DISCOUKSE III. External organs of Plants, — and their successive modifications. IN the preceding Discourse, we endeavored to furnish a definition, or distinct idea, of the three great kingdoms in Nature, — and, especially, to present a Sketch of the general resemblance, and dis- tinguishing characters, of the two organic kingdoms, from the learned Treatise of Professor DE CANDOLLE. We shall now proceed to notice some of the more remarkable traits, and phenomena, of the vegetable economy. For an illustration of the intimate struc- ture, and physiology of Plants, the Student is referred to the admirable Text-Book of Prof. A. GRAY : Our present purpose being merely to speak of the external organs, — or those obvious appen- dages, and features, which give character to the vegetable tribes, and form the basis of classification. It is a circumstance worthy of all attention, and admiration, that the works of Nature — even those apparently the most complicated and elaborate — are ever, when rightly understood, found to be per- formed with extremely few materials, and by the simplest of all possible processes. This truth is exemplified in the most interesting manner, in the structure and economy of Plants. Infinite as are the forms, and varied as is the texture, of the external organs of plants, — it has been satisfactorily shown, that all those protean appendages are, in fact, nothing more than a series of successive modifications (or metamorphoses, as they have been termed,) of that tissue which, in the germinating seeds, appears in the condition of crude cotyledons, — and which in subsequent stages — as the plants are developed and matured — is put forth in the more highly organized State of stem leaves, floral leaves (or bracts], sepals, petals, stamens , and pistils (or young fruit}. For an early, ample, and most interest- ing exposition of this doctrine, we are indebted to the celebrated PEELIMINAEY DISCOURSES. STl German Poet, GOETHE, — whose writings show him to have been no less accomplished in Botany, than eminent in Belles-Lettres. * In accordance with the view here presented, a Plant may proper- ly be said to consist of root, stem, and leaves ; — all other parts — under whatever name — being modifications of these. The limits assigned to these discourses forbid a complete illustration of the doctrine : but a brief sketch may be attempted, of the more strik- ing modifications which the external organs undergo, during the development of a plant: — i. e. in its progress from the germinat- ing seed, up to the perfection of its fruit. Those who read French, may find the doctrine elaborately set forth in SAINT-HILAIRE'S Mor- phologic Vegetate ; and in our own language, it may be found briefly but well explained, in the elementary works of GRAY, and LINDLEY. To prevent misapprehension, however, it may be well to let the student understand the precise and proper sense in which the term metamorphosis is used, by the Botanists. "When, for instance, the floral organs are called modified or metamorphosed leaves, it is not to be supposed that a petal has ever actually been a green leaf, and has subsequently assumed a more delicate texture and hue, or that stamens and pistils have previously existed in the state of foliage; but only that what is fundamentally one and the same organ developes, in the progressive evolution of the plant, under each or any of these various forms. When the individual organ has once fairly begun to develope, its destiny is fixed." — GRAY'S Text-Book. It has been aptly remarked, that the best mode of explaining things, is to show how they come to pass. That is the mode adopted by GOETHE, in explaining the metamorphosis now under consideration ; and it is the one we shall endeavor to pursue. It will be borne in mind, that a sound and perfect seed (by which is meant, one that is capable of vegetating,) is neither more nor less than a plant in miniature — rudimentary, it is true, but an organized, living plant, — existing in a dormant state, or what may be called suspended vitality. It awaits but the joint application of certain vivifying agents (namely, warmth, moisture, and oxygen,) to rouse it into active life ; when its bursts its envelopes, and com- mences its career of growth. The opinion, so generally entertained, * It is due, however, to truth and justice, to say, that very fev important doc- trines, or views, concerning the Vegetable kingdom, have yet been promulgated, of which " the immortal SWEDE " had not some intelligent perception. The idea so happily illustrated by GOETHE, had very nearly occurred to the mind of LINNAEUS, about the middle of the last century. It was first distinctly enunciated by C. I'R. WOLFF, in 17 64. PRELIMINARY DISCOURSES. that "seeds must die before they can come up," is a vulgar error. Seeds that die, never "come up." The error probably originated from observing the condition of the albumen, in seeds of the cerealia, or edible grains, at the period of germination. The efficient cause, or intimate nature, of growth, we do not, of course, pretend to understand. Such knowledge is now — and perhaps will remain — beyond the reach of finite beings ; but the physical agents concerned — their operations and results — and the laws which regulate them — the curious observer can both perceive and comprehend, to a very satisfactory extent. The solid portion of Plants is made up, mainly, of an infinity of slender fibres, and delicate membranes — forming tubes, and cells, for conveying and containing fluids ; and the physical process of growth consists in the extension and multiplica- tion of those tubes and cells. When the fibrous portion (which results from elongated cells,) predominates, the plant becomes firm and woody; and when the strictly cellular structure prevails — whether in stem, leaves, or fruit — the product is fleshy, tender and succulent. The same wise Power which endowed plants with vitality, and the capacity for growth, or development, has also established laws to control that development, — whereby each plant assumes a determinate form and character; which, although liable to variation in the subordinate features (as in texture, size, color, or other trait of secondary importance in the vegetable economy), are nevertheless essentially perpetuated in the species. It is this fixedness of character which enables the Botanist to recognize, and distinguish, the various kinds, — and, in classifying them, to ar- range each with its kindred. But our present business is with the changes or modifications, which successively take place, at successive stages of development, in the foliaceous appendages of the same plant. Naturalists have observed, that in the stems and branches of plants, there are small portions, found at certain intervals, which are more firm and dense than the other parts. These firmer portions are termed knots, or nodes, — and the intervening spaces are called internodes. These nodes exist, under some form, and in greater or less abundance, in all stems: sometimes being crowded together, and condensed at certain points of the stem, so as to form complete, and often solid" rings (or joints, as they have been rather incorrectly termed) ; at others, they are much divided, and appear in scattered points on the circumference, — in which latter case, they are usually disposed in an ascending spiral line. They seem to have an intimate con- nection with the formation of all leaves, and buds, — and are, at least, PBELIMINARY DISCOURSES. XlX the starting points from which those organs are evolved, during the growth of the plant.* Even the stem of the embryo plant, as it exists in the seed, has its nodes, — with the first of which the cotyledons are connected, and at the next above, we find those minute expan- sions known by the name of primordial leaves. The internode*, or spaces between those little knots in the stem, may be long, or short, — which will, of course, determine the distance between the leaves. They may be so short as scarcely to be perceptible, — in which case the leaves will necessarily be brought close together, in tufts or bunches ; or they may even be wholly suppressed, as it is termed, — so as to reduce the leaves to the same plane ; either in opposite pairs, if but turn are developed, — or in vchorls of the normal number in the circuit of the stem, if all are developed. If the nodes are scattered, or disposed in a spiral line, the leaves, of course, will be arranged in the same order, on the stem and branches. Thus we are furnished with a key to the whole mystery of the arrangement of leaves and buds, — and consequently, of the branches, which arise from the buds. We shall now be prepared to watch the development of the foliaceous appendages of the plant, — and the successive changes of their form and character, as the stem ascends. The cotyledons (in that large division of the vegetable kingdom which is provided with two of those organs,) are always opposite, — as likewise are, for the most part, the next pair of leaves — called primordial : but the suc- ceeding ones are variously arranged, in different families — either alternate, opposite, or vtrticillate. The leaves on the stem, and branches, usually differ in form, also, from those early rudimentai leaves which appear at germination. If the plant is duly nourished, the leaves are apt to be well developed until it has reached its destined height — or is sufficiently matured far flowering, — when they usually become smaller. In several natural families, there are foliaceous appendages, or accompaniments, at the base of the leaves, or petioles, which seem to be a sort of exuberant growth, or super- numerary products : these are called stipules. In sterile, or ungenial soils, the leafy expansions are less com- plete, and are liable to modifications which appear to be the acci- dental result of defective nourishment, — though they often become fixed, and permanently characteristic. Prof. DE CANDOLLE terms * Sometimes the bud— instead of being in the axil of the leaf, as is usual— is formed and situated directly under, and within, the base of (he petiok ; in which case, consequently, the hollow base of the petiole covers the bud, as an extin- guisher does the stump of a candle. This feature is well exhibited, in autumn, by the Buttonwood Tree (Platanus); and may be likewise observed in the common petioles of the Bhus, the Rdbinia, and the Cladrattis (or Virgilia). XX PRELIMINARY DISCOURSES. the process, degentrescence — i. e. a sort of degeneracy, or habitually stunted growth, Thus, in some plants, we find the true stem-leaves habitually curtailed of their fair proportions, — compound leaves being reduced to simple disks, or dilated petioles, called phyllodia, — simple leaves starved into mere needle-like processes, — and stipules shrunk into prickles ; while even woody branches, under a similar privation, often appear in the character of true thorns. By taking this view of the vegetable economy, we are not only led to contem- plate the various modifications with great interest — but are put completely on our guard against any illusion, or misapprehension of the real nature of apparent irregularities, or so-called anomalies. — We know that the proper place to find a leaf, is at the nodes: "We shall generally find one there. It will sometimes be very small — sometimes reduced to a mere scale, or midrib — or it may even be entirely wanting ; but that's the place to look for it, — and if we find any thing occupying the normal position of a leaf, or stipule, we shall be prepared to understand its true character. So of the other organs. Whatever strange-looking appendage we may find in the proper position of any organ, — we shall at once comprehend, that it is some disguised form, or modification, of that particular organ.* * This view of the subject, I would wish to impress strongly, and distinctly, on the mind of the Botanical Student. Every organ of a plant being liable to modi- fication, we must take care not to be misled by appearances ; but be constantly suspicious of all disguises, or deviations from regular structure, and symmetry. — The clew to real character — as intimated in the text — will be afforded by the posi- tion of an organ. In the grape-vine, for example, those anomalous organs, called tendrils, will be found occupying the normal position of flowering branches; and observation has shown that they are, in fact, nothing but abortive or metamor < phosed racemes. They may be often seen in the transition state, — some of the subdivisions of the tendrils actually l>e&ringjlou>ers. Prof. DE CANDOLLE even con- sidered the main stems of twining plants as partaking of the character, and verg- ing towards the condition, of tendrils ; and his opinion is rendered plausible by what we see in many climbers. In some species of Clematis, and in Adltimia, the petioles, or footstalks of the leaves, perform the office; and in the vetches, or Pea tribe, the common petioles usually terminate in real tendrils. In certain leafless plants — such as the Opuntia, or prickly Pear, and some species of Phyllanthus, — the stem assumes the flat, dilated figure — and, to some extent, actually performs the function — of leaves : But, with the aid of our Theory, there is no danger of mistaking the real character of any of these " counterfeit presentments." The change of calyx, and receptacle, into apparent fruit — by reason of the copious development of cellular tissue, in those organs, is not an unusual occur- rence. Their position, however, in relation to the other parts of the flower, ren- ders the circumstance perfectly intelligible.. The gradual conversion of pistils, or carpels, into the countless varieties of mature fruit, is readily explained by this development of tissues. In their early, rudimental stage, at the opening of the flowers, the texture of the carpels is very similar in all plants; but, during their growth, and progress to maturity, a great change is effected in the different PRELIMINARY DISCOURSES. Xxl When a plant is full-grown, or sufficiently matured to bloom, a striking change takes place. Slender branches are often thrown out, — or the internodes near the summit of the stem become suddenly elongated ; there is usually, also, a great diminution observable in the size — and frequently an entire change in the outline, or figure — of the foliage, on the flowering branches. Next we find, in many instances, a sort of transition leaves, called bracts, in the immediate vicinity of the flowers. These bracts are sometimes scarcely changed, in appearance, from the other leaves on the stem and branches ; but we find them, occasionally, assuming the hue, and almost the tex- ture, of petals. Having thus ascertained that bracts are nothing more than modified leaves, — we now approach the flower, itself, — which is always the termination, or concluding development, of a stem, or branch;* and here we find, in many plants, a whorl of green leaflets (or sepals — composing what is called the calyx,} at the base of the flower, so little altered from the small leaves immediate- ly below, that we have no hesitation in considering them as of precisely the same nature; — the only difference being, that, by the suppression of internodes, they are arranged in a ring (called a verticil, or whorl,) at the summit of the peduncle, or ultimate branch of the flower-stalk. This is the regular mode of arrangement, of all the parts of a flower. The sepals, petals, stamens — and even the pistils, in symmetrical flowers (i. e. when all the parts, which normally belong to them, are present) — are all disposed in a succession of verticils. In the flowers of the DICOTYLEDONS, or Exogenous Plants, each floral verticil, when complete, is composed of five modified leaves — or some multiple of that number. It may — and often does — vary from this, by reason of a suppression of some of the parts ; but five is the normal, or what may be termed the constitutional number, in the floral verticils of that great division of the vegetable king- kinds — according as the rascular and fibrous, or the cellular, tissue predominate?. In the one case, we have dry, skinny, woody, or even bony, seedvessels; and in the other, we find the product to be Qeshy, pulpy and succulent fruits. Even in the same pericarp, we often see one portion tender and juicy, — while another portion is parchment-like, or bony; as in pomes, and drupes — or apples and cherries. It is only necessary to extend and apply this doctrine to all the modified organs of plants — and to keep the idea constantly in mind — in order to compre- hend the whole mystery of metamorphosis. * Although, for convenience in descriptive phraseology, we often say that flowers are lateral, axillary, sessile, Ac., it should, nevertheless, be constantly borne in mind, that a flower is always the terminal and crowning development — as the fruit is the final product— -of a stem, or branch; that the pedicels of aggregated florets are the ultimate ramifications of the main flowering stalk, — and that wheu a flower appears to be sessile, it is merely by the suppression — more or less com* pletc — of the internode which normally constitutes its proper peduncle. SX11 PRELIMINARY DISCOURSES. clom. Often, indeed, one or more entire verticils are suppressed, — presenting flowers destitute of calyx, or corolla — or sometimes with one of these, and either the stamens, or pistils, also wanting.* In the MONOCOTYLEDONS, or Endogenous Plants, — such as the Liliaceous and Orchideous tribes, Grasses, Sedges, &c., — three, and its multiples, constitute the regular, symmetrical number, of the members of each floral verticil ; but they are often incomplete, or wholly suppressed. In the Liliaceae, we frequently find some of them doubled, — while in the Grasses, and Cyperaceae, all but the ataminate verticil are usually deficient. The leaflets, or component parts of the several verticils, are in many instances all free — i. e. separate and distinct from each other ; and this is regarded as their normal or regular condition : But we often find them united, or cohering together, to- a greater or less extent — either by their margins, or surfaces, or both ; and this union is apt greatly to disguise their primitive character. Such cohesions, or solderings, as they are termed, are analogous to the process of ingrafting, or rather inarching, — and may be readily sup- posed to take place while the tender organs are closely packed together, in their forming stage. Sometimes the sepals are united by their margins, so as to form a cup, at the base of the flower, — and this suggested the name of calyx. When the union is nearly com- plete, a careless obserrer might be puzzled to know whether the calyx were really compound, or simple, in its structure ; but our theory leadsus to lo-ok for evidences of a compound structure, — and we accordingly find them in the free points of the sepals, which are usually obviows enough, under the name of segments, or teeth, — and also in the seams, or sutures, formed by the junction of the margins. The union of the petals is often quite as remarkable as that of the sepals, and sometimes greatly obscures the normal struc- ture,— as we see in what are called personate, and labiate flowers. Similar cohesions take place, likewise, among the stamens, and pistils. The modified leaflets, or parts of the same floral verticil, are not only liable to cohere with each other, — but the different verticils are also frequently soldered together, at base — so as to form * Flowers are termed symmetrical, when all the parts of each verticil are devel- oped; regular, where the parts, present in a verticil, are all of the same form and size; complete, when both calyx and corolla are present; and perfect, when each flower is furnished with both stamens and pistils. When stamens, or pistils, are defective, or wanting in & portion of the flowers, while they are perfectly developed in others, the flowers are said to be polygamous ; and they are termed monoicous, or dioicous, when simply staminate, or pistillate, — according to their distribution OB the same, or on different, plants. PRELIMINARY DISCOURSES. XX111 one concrete mass ; in which case the ovary (or young fruit) appears to be below the flower, and is said to be inferior, though it is really above, — being within the tube, formed by the cohering sepals, &c., and consolidated therewith. The next regular verticil, above the calyx, is called the corolla. The leaflets of this, are usually much more changed than those of the calyx; but even here, we find such various intermediate forms as clearly show that the petals, also, are nothing but modified foliage. In further corroboration of this view, we observe in many plants what seems to be a kind of supernumerary verticil, — sometimes situ- ated between the calyx and corolla, and sometimes between the corolla and the stamens ; which supernumeraries are apt to be very curiously modified, — and are obviously in a state of transition, either from sepals to petals, or from petals to stamens. These are com- monly called nectaries. The same remarks apply to the two remain- ing regular verticils of the flower, known as stamens, and pistils. Singular as it may seem, to the uninitiated, even those organs are now regarded as leaflets, which have reached the final stage of metamorphosis ; for both have been detected in such form and condi- tion as clearly betrayed their foliaceous origin. The reciprocal con- vertibility of petals and stamens, is a fact familiar to every Tyro in Botany. All double flowers — so common under high garden culture — are familiar examples of staminate verticils being expanded into petals, instead of conforming to the regular law of their nature ; and hence, those exuberant developments — so much admired by Florists — are considered by Naturalists as accidents, or monstros- ities. The pistils, too — which comprise the young fruit— although less frequently, are subject to a similar imperfection ; and the very ovules, or rudiments of seeds, have been found retrograding, — so as to exhibit their tender cotyledons in the form of leafy expansions.* Thus, it appears that the whole of the external organs of a Plant may be fairly regarded as so many leaves, in various successive *Each simple pistil may be regarded as & folded leaflet, in the last stage of modi- fication, preparatory to the formation of ovules, — and is often termed a carpel, or little fruit. The ovules are usually produced on the margins of the metamorphos- ed leaf, — and arc arranged on the placenta (supposed to be formed by the union or decurrence of their pedicels), along the seam, formed by the junction of those margins. When there are several pistils, or carpels, in one flower — and those soldered together, — we have, of course, a compound fruit, with several cells; i. e. a cell for each carpel. But some of the ovules — and even entire cells, or carpels — may be, and often are, wholly suppressed, or abortive; thereby impairing the symmetry of the structure — but leaving the phenomenon perfectly intelligible. XX1Y PRELIMINARY DISCOURSES. stages of metamorphosis, from their origin to their end — from seed to seed again. DISCOURSE IV. Classification of Plants. Artificial and Natural Methods. HAVING seen that the external organs of Plants consist, funda- mentally, of those appendages called leaves, — which are regularly modified, and prepared for their several functions, at the successive stages of the vegetable career, — we shall now proceed to notice some of the Methods, by which Naturalists have proposed to facilitate a more extended and particular acquaintance with the different kinds: — i. e. with the Genera, and Species, of the vegetable king- dom. Although the organs of the various tribes assume an almost endless variety of forms, and aspects — and even in the same species, are subject to considerable modification, by the influence of culture, soil, climate, and other circumstances, — it has been observed, never- theless, that the peculiar structure, and essential character, of each particular family, are remarkably constant, and well defined. Even the monstrosities produced by long culture, disease, or other accident, usually retain enough of their primitive features to enable us to recognize them, under all their disguises. It is this constancy, or permanence of character, which affords the basis of all classification ; and classification, or the grouping together of kindred individuals, is the apparatus by which our conceptions of objects are so arranged, and fixed, as to secure a comprehensive general view, — while it facilitates all subordinate and detailed investigations.* The most important, or conspicuous organs of plants — their most constant and characteristic features — whether consisting in the struc- ture, the presence, or even the absence, of particular parts, have *It would be impracticable, without the machinery of classification, to make any important advances in Natural knowledge, — or to leave any durable traces of our progress, in such knowledge, for the benefit of those who come after us. To use a nautical term, we must bday all the information we acquire, if we wish to render it permanently available to others : and the best belaying fixtures, to pre- vent entanglement and confusion in Natural History, will be found in the most lucid and practical systematic arrangement. " Omnia " — says LINNAEUS — " quae a nobis vere dignosci possunt, dependent a CLARA METHODO, qua distinguimus similia a dissimitibus." PRELIMINARY DISCOURSES. XXV accordingly been employed by the early Botanists, in constructing systems of classification.* Some have based the arrangement on the texture and size of plants — classing them in divisions of Herbs, Shrubt, and Trees; others, again, on the structure and form of the Calyx, the Corolla, the Fruit, &c. or on the presence, or absence, of some important organ: And, in our own times, the favorite object — following JUSSIEU and DE CANDOLLE — is to arrange plants strictly according to their affinities, — to group together, in Orders and Tribes, those which are most nearly related in all the features, and properties, which constitute character. These various Systems may be all regarded as forming only two kinds, — namely, the Artificial, and Natural Methods; — though, in point of fact, the artificial methods are more or less founded in Nature, — and in the most perfect natural arrangements, yet devised, artificial sections, or groupings, are still resorted to, as useful helps and expedients. "What we call a natural method" — says the excellent Prof. GRAY — "is so termed merely because it ex- presses the natural relationship of plants as far as practicable ; for every form yet contrived, or likely to be devised, is to a considerable extent, artificial." The great and obvious defect of the methods called artificial, con- sists in their being founded on the fewest possible characters, — whereby plants are arbitrarily brought together without reference to their intimate structure, or general relationship with each other ; and hence it often happens, in such methods, that plants which are essentially dissimilar, are arranged side by side ; while kindred species are widely separated. This defect is inherent in all artificial systems ; and therefore, the most of them are only tolerable on account of the facilities which they afford in determining unknown genera and species — or ascertaining the names of particular plants. The system, however, which was devised by the celebrated LINNAEUS, has the merit of combining some of the advantages of both the artificial and natural methods ; and will probably long continue to be employed, as a convenient and useful help to the investigations of young Beginners. It is, indeed, very remarkable, how many natural families of plants are kept nearly entire, under the Sexual System. The Linnaean classification, of the flowering plants, is founded on the characters of two of their most important organs, — namely, the * The late Professor B. S. BARTON, in his Elements of Botany, has given a Syn- opsis of seventeen different methods of artificial arrangement,— from that ofCAESAL- PISUS, "the Father of Systematic Botany"— which was published in 1583— down to the Linnaean method, as modified by THUXBERG, near the close of the last century. As a matter of curiosity, they are worth consulting. XXVI PRELIMINARY DISCOURSES. ttamens, and the pistils. The primary divisions, or Classes, are established mainly on the number, situation, proportion, and connec- tion, of the stamens ; while a large portion of the secondary divisions, or Orders, is based simply on the number of the pistils. Some exceptions occur in the foundation of the Orders : but they are all very intelligible, and readily understood by the student. It is obvious, therefore, that nothing can be easier to acquire, than a knowledge of the Linnean Classes and Orders. The practiced eye — even in a flower that it has never before seen — determines them at a glance. The genus, and species — which are the remaining subdivisions — are to be ascertained as in all other systems; the former, from the structure of the flower and fruit, — the latter, from the peculiar and permanent characters of the residue of the plant. It has been often objected to the Linnaean method, that there are too many exceptions to the rules of classification, — that a num- ber of genera comprise species which, according to the system, belong to a different Class, or Order, — and thus mislead and puzzle the student. This objection is undoubtedly founded on fact ; but the inconvenience has been somewhat exaggerated, — and may be greatly remedied, and almost obviated, by simply putting a list of those anomalies at the foot of the respective orders, where the sys- tem would lead us to look for them. Where this is carefully done, it even seems to facilitate the determination of such irregular species, — directly pointing them out by name, and designating the genera to which they severally belong. It may be questioned, moreover, whether the exceptions in the definitions of many natural Orders, are not even more numerous than those complained of in the Linnaean method. Instructive, and delightfully interesting, as is the contemplation of the truly natural families, — it seems to be necessary to make the definitions of some of them very loose, and comprehensive, in order to embrace all the individuals admitted to belong to them : * so much so, indeed, that unless the student has * Take, for instance, the very first family, in Prof. DE CANDOILE'S method of arrangement — viz. the order RANUNCCLACEAE ; where we find the following diver- sified— not to say incongruous — characters, enumerated in the definition of the order:— Her bs, or woody vines, with leaves variously dissected, or entire— polypetal- ous, or apetalous — flowers regular, or irregular — sepals 5, 3, or 15 — petals 3 to 15, or wanting — stamens indefinite, rarely few— pistils many, or few, rarely single — fruits either dry pods, or akenes, or berries, 1, or several-seeded ! This is, unques- tionably, a correct outline of the features of a natural family — sketched, too, by the hand of a master; yet, a Beginner in Botany would probably be apt to think that as a definition, it is rather indefinite,— and he would, no doubt, be thankful for any artificial helps that might tend to facilitate his researches. PRELIMINARY DISCOURSES. XXTll already acquired a considerable knowledge of the vegetable tribes, he often finds himself puzzled, and discouraged, in his attempts to ascertain the names, and true position among them, of specimens which are new and strange to him. In order to abate this incon- venience, it has been found expedient, from time to time, to remove the most discordant members of the old families, and make them the types of new orders ; and in this way, the number of the orders has been exceedingly multiplied. In fact, their name is legion ; and the danger is, that it will soon be more difficult for the young Botanist to ascertain the natural Order of a strange plant, than it was to determine the genus and species, by the Linnaean method. The learned and sagacious JUSSIEU — who first elaborated and published a Natural System, in 1789, — arranged the vegetable kingdom in 15 Classes, and 100 natural Orders, or Families: but the great work of ENDLICHER, in 1840, gives us no less than 61 Classes, and 277 Orders, — with Tribes, and Sub-tribes, almost in- numerable. These Orders are continually multiplying ; for, when- ever the acute investigations of our modern Botanists detect incom- patibilities in any member of an existing family, a new Order is forthwith created, for its reception and accommodation. The ex- pedient is very convenient — and no doubt very proper : though it obviously threatens to result in an appalling multitude of Orders, — which may require some artificial devices, to furnish a practical clew to the position of unknown plants, in the great labyrinth of Flora. But, after all — however convenient and agreeable may be the aids afforded to the Beginner, by artificial methods, — and however intractable some genera may be, in associating with any known natural Orders,— it must be confessed, that the method which teaches us to investigate the essential characters and true relations of plants, and which enables us to arrange them in kindred groups, according to their respective affinities, is the only true philosophical Botany;— the only method, in short, which entitles the pursuit to the appellation of a Science. Although— as we have just intimated — the relationship between the members of some natural orders, as at present constituted, is not very striking, — yet there are numerous and vast groups, composed of plants so obviously related to each other, that all the world — both learned and unlearned — have con- curred in referring them to the same family. Of these, it is suf- ficient to mention, here, the great natural Orders of Grasses, Um- belliferous, and Leguminous Plants— and those bearing what are called Syngenesious, or Compound Flowers. We may add, moreover, XXVlll PRELIMINARY DISCOURSES. that those anomalous structures, which seem to have no immediate connections — and are, at present, excluded from every known Order, — may yet find near relatives in the unexplored regions of the vegetable creation; and that future discoveries may possibly sup- ply all the links, which now appear to be wanting, in the great chain of organic existences. In the mean time, — to those who are commencing the study of Botany — and especially to such as have no other aid than books, — I would say — Avail yourselves of the Linnaean Method, as the easiest stepping-stone to the vestibule of the temple, and the readiest means of acquiring the names, and learning some of the characteristics, of the more common plants around you. In this way, an immediate interest in the pursuit will be excited, — which is indispensable, and can only be effected by successful research ; for, if the student is met by repulsive difficulties at the threshold, he is apt to be discouraged, and to abandon the undertaking.* But, while I concede this much, in order to enlist you in the delightful enterprise, I would add, and earnestly enjoin upon you — as soon as you have effected these preliminaries — to make-it an invariable rule to refer every plant to its appropriate place in the Natural System ; to study its characteristic features, and examine with a scrutinizing eye, all its relations to kindred objects. I would furthermore recommend, to all who are bent upon mastering the Science, to commence a Herbarium, from the start, •f Establish a correspondence, * While I admit that a mere acquaintance with the names of objects, is the most superficial kind of natural knowledge, — observation has satisfied me, that even such knowledge is useful to Beginners in the Science, by the early encourage- ment, and hopeful stimulus, which it imparts to their researches. I think there is force, and good sense, in the following passage from a writer in the last century : — " Let it be considered that the first degree of wisdom is to know things when we see them — i. e. to know them by their names; and without this knowledge scarce any progress can be made. To know the letters of the alphabet, to join them into syllables, to understand words, is not solid erudition; yet it is absolutely necessary for him who would become learned. Thus the characters and names of things must be thoroughly learned in order to obtain any use from Natural History. We find in the journals of travellers, many things mentioned, partly curious, partly useful, concerning animals, plants, and stones; but those obser- vations can be of no use to us, till we are able to refer each to its genus; that we may make them a part of the system, and know that this curiosity, or use, belongs to this or that object, when it happens to come in our way." — GEDNER, in STILLING- FLEET'S Tracts. fThe young Botanist should make it a rule to collect and preserve good speci- mens (one or two for himself, and some for his friends,) of every species, and remarkable variety, that occurs to him in his walks ; labeling them carefully — •with the name, when known, — but, whether known or not, at once, and invari- ably, noting the place of growth, and the time when obtained, — together with any PRELIMINARY DISCOURSES. XXIX and a system of exchanges, where practicable, with competent and zealous Botanists, in other districts. Be very inquisitive, whenever you have a chance to confer with such, — for they are always happy to aid the researches of the hopeful student ; furnish them with specimens, and ply them with questions. Questions, when rightly directed, and intelligently put, are a most effective apparatus for eliciting information, and bringing truth from her hiding place. A witty rhymer, of the age just elapsed, thus quaintly, yet aptly, illustrates the character and importance of Interrogatories : "The Sages say, Dame Truth delights to dwell— Strange mansion ! in the bottom of a well : Questions are then the windlass and the rope, That pull the grave old Gentlewoman up." The acquisition of the Language of Botany — or those technical terms which are necessarily employed in the Science, — is generally considered, by Beginners, as a most formidable part of the under- taking: But this will be found, in a great degree, to be an im- aginary difficulty. I admit that it would be a task, as irksome as it would be unprofitable, to attempt ty learn the meaning of a parcel of uncouth terms, without knowing their origin, or comprehending the objects to which they are applied. Such is not the mode in which I would study, or try to teach, the natural sciences. Rather let us look at the objects, and examine their structure. We shall characteristics which are liable to be obliterated in pressing and drying.f These notes will serve him as valuable Mnemonics, in any future references to his Herbarium. On all suitable occasions, he should diligently explore the vegetable products of the region, or district, where he resides :— not neglecting such other localities as he may happen to visit. In that way, he will soon be surprised at the extent and value of his collections; and will find a pleasure, and an interest, in Lis herborizing excursions, which the uninitiated can neither appreciate nor com- prehend. In those excursions, a friend who can sympathize with his predilections, and cordially participate in his researches, will always prove an agreeable and useful companion: But I .fully concur in the shrewd advice of my old Correspondent, Dr. E. GERMAIN, DE SAINT-PIERRE, in his Guide du Sotaniste:— "Jamais, n'herborisez avec les personnes etrangeres a vos etudes; vous les fatigueriez bien vite par vos allures irreguliercs, vos terns d'arret ou votre marche precipitee ; tandis quo, d'autre part, 1'air contrarie de votre compagnon, prive d'un auditeur et s'etonnant que vous regardicz une plante commune ou vous demandant si vous ne 1'avez pas dejk recoltee, vous serait a vous memo une in- supportable gene. Gardez-vous surtout d'entreprendre, dans de telles conditions, un long voyage : son but serait absolument manque." fin collecting plants for & Herbarium, and future examination, it is always desirable, when practicable, to have specimens of the fruit, — as well as of the flowers, leaves, &c. " Every botanical specimen," says Prof. HARVEY, "should bo an epitome of the essential marks of a species." The Student should distinctly understand, that the full grown fruit is indispensable in determining many of the Carices,— and also of the Cruciferae, and Umbelliferae. He should, therefore, be careful to make hia collections accordingly. XXX PRELIMINARY DISCOURSES. then perceive organs, or features, which serve as convenient marks of distinction between different objects. Those organs must neces- sarily be designated by some name, or term — in order that they may be intelligibly spoken of, or recognized when referred to : and I venture to say, that every one who makes an acquaintance with such objects, — so far from finding the names to be burthen- some — will feel the absolute necessity of them; and will take a lively interest in their acquisition. We should undoubtedly find it a dull and insipid employment, to take up a City Directory, and commit to memory the names of the Inhabitants : But, if we were to go among them, and form some interesting acquaintances, we should find no difficulty — nor should think it any trouble — to learn the names of our new friends. Now, the process should be precisely similar, in the study of Nature. We ought never to waste our precious time in learning mere names, apart from objects, — nor in attempting to load the memory with such useless lumber. I say attempting ; for it is not possible to fix permanently in the memory, any names which are not associated with something like distinct conceptions of the things to which they are applied. Such abstractions amount to nothing more than an unmeaning jargon ; and therefore speedily vanish from the mind. I repeat it, then, that in the NaturaJ Sciences, the study of names, and things, should always go together. DISCOURSE V. Linnaean Classification. Natural System. THE Linnaean method of Classification — as has been already stated — is based chiefly on the stamens and pistils ; and is, con- sequently, attended with this inconvenience, — that the class of an unknown plant can only be determined, with certainty, while it is in flower. The flowering season, to be sure, is the most agreeable time to botanize ; but we cannot always procure our specimens in that interesting state, — and hence we soon discover the advantage of such a general knowledge of vegetable structure, as is afforded by the study of the natural system. LINNAEUS arranged the whole vegetable kingdom in 24 CLASSES, — 23 of which are appropriated to flowering plants, and are founded on some circumstance of the stamens, — the 24th being established PRELIMINARY DISCOURSES. XXXI on tlie absence of visible flowers. The first 13 classes are disposed numerically, — according to the number of distinct stamens, of about equal length, inserted on the receptacle of each flower, — with the exception of the 12th (Icosandria], in which the stamens (occasion- ally few, and sometimes very numerous — though usually about twenty, as the name indicates,) are inserted on the calyx; and it is this insertion which constitutes the essential character of the 12th Class. From Class 1 to 10, inclusive, the number of stamens is the same as the number of the Class. The llth Linnaean Class (called Dodecandria — meaning 12 stamens) was made to comprise all plants with more than 10 and less than 20 stamens; but such plants — being few in number — have been referred (very judiciously, as I think), by some modern Botanists, to the Class Polyandria, — which, consequently, contains all plants with more than 10, distinct, or separable stamens, inserted on the receptacle. The Class next after Polyandria (called Didynamia — 14th of LINNAEUS), contains plants having 4 distinct stamens in unequal pairs — one pair being regularly longer than the other; and the succeeding Class (Tetr adynamia,) has 6 distinct, unequal stamens, — 4 of them being longer, and 2 opposite ones short. The next three Classes are founded on the union of the stamens, — or rather of their filaments — the anthers being free: the Class Monadelphia usually having numerous stamens, with the filaments all united together in a tube, or single set ; the Class Diadelphia having mostly 10 stamens, with the filaments united in two sets (usually 9 and 1), and the corolla generally in the form called papilionaceous, or butterfly-shaped ; and the Class Polya- delphia having numerous stamens, united in three or more sets, — but, as the union is often slight, and the filaments — especially in dried specimens — incline to separate, the plants of this Class have been referred to Polyandria. The Class next following those with united filaments, is a very large one, with united anthers (named Syngenesia], and what are called compound flowers — i. e. the floral developments (which are often large and showy,) are really composed of many little flowers, densely crowded in heads, on a common receptacle, — the heads being embraced, or supported, by numerous bract-like leaflets, which constitute what is termed the involucre. The succeeding Class (Gynandria,] has the stamens inserted on the pistils — or those organs so united, and often so intimately blended, as to render them rather obscure, to the inex- perienced observer. In the preceding Classes, the stamens and pistils are mostly in the tame flower; but in the three following — which conclude the XXxii PRELIMINAKY DISCOUKSES. flowering plants — those organs are generally in separate flowers, — and are thus classified: — In the 21st Linnaean Class, named Monoe- cia, the stamens and pistils are in separate flowers, on the same plant: In the next Class, called Dioecia, they not only occupy separate flowers, but those flowers are on different plants. There are, however, a number of plants, in which the stamens and pistils are separate in some flowers, and associated in others — either on the same, or on two, or even three, different plants. These anomalies, LINNAEUS placed in a Class which he named Polygamia ; but they have been, by later Botanists, distributed among the other Classes. The 24th, or last, of the Linnaean Classes (now more commonly numbered as the 21st), is named Cryptogamia. It comprises those multitudinous vegetable forms which seem to be destitute of flowers, — or, at most, have only the analogues, or equivalents, of stamens and pistils. The subdivisions of this Class are, of necessity, in accordance with the natural system ; and the genera are therefore grouped in appropriate Orders — as Ferns, Mosses, Lichens, Fungi, and Algae. The ORDERS, or secondary divisions, of all the Linnaean Classes — from Monandria to Polyandria, inclusive — are founded on the number of distinct styles, or stigmas, — and are numerically arranged. The Class Didynamia is divided into two Orders : — one, called Gym- nospermia, because it produces a thin-coated, and usually 4-lobed, fruit, resembling naked seeds, or nutlets : the other, bearing mani- fest seedvessels, and therefore named Angiospermia. The Class Tetradynamia is likewise divided into two Orders — founded on the size, or rather length, of the fruit, one, called Siliculosa, having a Silicle or short pod, — and the other, Siliquosa, with a Silique or long pod. In the remaining Classes of the flowering plants — with the exception of Syngenesia — the Orders are established on the number, or connection of the stamens. The Orders of the Class Syngenesia are founded on the florets, in the compound heads, — and are as follows : — 1. Polygamia aequalis, where the florets are all perfect. 2. P superflua, where the central, or disk florets are perfect, and the ray florets are merely pistillate. 3. P fruslranea, where the disk florets are perfect, and the ray florets neutral (or vacant). 4. P necessaria, where the disk florets are staminatc, and the r ay florets pistillate. PEELIMINAEY DISCOURSES; 5. P segregata, where each floret in th&- head1 has a kind of involucre of its own — separating it from the others. The Orders of the Cryptogamia, or 24th Linnaaan Class, have been already noticed, as being necessarily natural.. By distributing the Genera, which LINNAEUS placed in Dodecandria, Polyadelphia,. and Polygamia, among the other Classes, the number of those pri- mary divisions may be reduced to 21, withoujt any detriment to the System. The simplicity and elegance of this method — the facility with which it is learnt, and applied— are considerations which have made it extensively popular, — especially with young Botanists: and although it is avowedly artificial',, the fact of its bringing so many genera into natural groups, is strong evidence that it is based on the most important organs in the vegetable economy.* I shall now conclude these desultory Discourses, by an attempt briefly to indicate the mode in which Plants are classified, and viewed, under the Natural System. The object proposed by that System, is "to bring together into groups those plants which most nearly resemble each other, not in a single and perhaps unimportant point (as in an artificial classification), but in all essential particu- lars ; f and to combine the subordinate groups into larger natural assemblages, and these into still more comprehensive divisions, so as to embrace the whole vegetable kingdom in a methodical arrange- ment. All the characters which plants present, that is, all the points of agreement or difference, are employed in their classifica- tion ; those which are common to the greatest number of plants being used for the primary grand divisions;, those less comprehen- eive for subordinate groups, &c. ; so that the character, or descrip- tion of each group, when fully given, actually expresses all the known particulars in which the plants it embraces agree among themselves, and differ from other groups of the same rank. This * The most superficial observer cannot fail to be struck with the fact, that the Sexual System groups together — with comparatively few exceptions — the genera belonging to the following eminently natural — and some of them eminently large — families of flowering plants : namely. Cruciferae, Malvaceae, Leguminosae, Hosaceae, UmbeHiferae, Compos itae, Labiatae,Boraginaceae, Orchidaceae, Cyperaceae, and Gramineae, — not to mention a number of others, wh ich will occur to the experienced Botanist, as more or less approximating a natural association. •{•The Njtiurallt'—s&ys Prof. DE CxyooLLE— arranges or groups together all those beings which have the greatest number of organs in common, or of similar struc- ture,— and separates those which possess but a small number of them in common : whence it results that, while the perfection of an Artificial System consists in connecting with the character of the Classes the smallest possible number of ideas, — a Natural Method, on the contrary, is so much the more perfect, as thu characters of the Classes are expressive of a greater number of ideas, UNIVERSITY PRELIMINARY DISCOURSES. complete analysis being carried through the system, from the primary divisions down to the species, it is evident that the study of a single plant of each group will give a correct general idea of the structure, habits, and even the sensible properties, of the whole." — GRAY'S Text-book. The vegetable kingdom, viewed in reference to the natural system, is divided primarily into two great SERIES, — a higher one, called phaenogamous or flowering plants producing proper flowers (with stamens and pistils), and seeds containing a ready-formed embryo or young plantlet — and a lower one, called cryptogamous orflowerless plants, which are reproduced by little cellular analogues or equivalents of seeds, termed spores, without the agency of proper flowers. The higher SERIES (or flowering plants) — which embraces the larger and more important portion of the vegetable kingdom — is divided into two Classes, named Exogens, and Endogens. The difference between these two Classes pervades their whole port and aspect, and is manifest from their earliest stage of existence. The embryo of Exogens is provided with a pair of opposite cotyledons (rarely with more than two — as in some of the Coniferae, or Pine family), — that of Endogens, with only one,- whence the former have been also termed Dicotyledonous, and the latter, Monocotyledonous plants. — There is a remarkable difference, likewise, in their foliage; the leaves of the Exogens generally having reticulated or netted veins, and falling off by an articulation, or separable joint, — while the Endogens have nearly parallel-veined leaves, which are not articu- lated, but wither on the stem. The class of Exogens is divided into two Sub- Classes ; the one, much larger, bearing their seeds in a proper Pericarp, or closed Seedvessel, and hence called Angiosperms ; the other (containing a couple of Orders), having the seeds naked, — i. e. borne on an open scale, or seated in a fleshy disk, — andtherefore called Gymnosperms. The Subclass of Angiosperms contains so many Orders, that it has been found convenient to adopt some rather artificial divisions, based on the character, or absence, of the Corolla. The first division comprises those exogenous plants, in which the petals of the flower are all nearly or quite distinct, or separate from each other, — and are termed polypelalous, or more accurately, dialypetalous Exogens. The second division is composed of those in which the petals are more or less completely united by their margins into one piece — forming a sort of tubular corolla, — and the plants of this division have been called monopetalous, but more properly gamo- petalous Exogens. PRELIMINARY DISCOURSES. XXXV The third division includes those in which the Corolla (and occasionally the Calyx, also,) is wanting ; — and the plants of this division are therefore called apetalous Exogens. A few exceptions, however, occur in each of these divisions (as in every other arrange- ment, yet devised — whether natural, or artificial) ; which will be noticed in the proper places. The Subclass of Gymnosperms — as already mentioned — consists of a couple of Orders ; viz. the Coniferae, or Pine Family, — and the Cycadaceae — a small tropical Order, — in which the pistil is repre- sented by an open scale, or by a more evident leaf, — or sometimes entirely wanting ; and the ovules and seeds consequently naked — i. e. not included in a pericarp. The above are the principal divisions of the great Class of Exogenous Plants: But these (as in the other Classes,) are again sub-divided into Groups, Orders, Suborders, Tribes, Subtribes, Genera, Subgenera, Species, and Varieties. The Groups comprise kindred Orders, — while the Orders and Tribes consist of kindred Genera, and usually derive their names from some well-defined typical Genus (as Malvaceae, or Rosaceae),- — or some characteristic family feature (as Umbelliferae, or Leguminbsae).* The Class of Endogens — partially defined above — does not admit of so many principal divisions, as the preceding ; but contains a number of well-characterized Orders and Tribes, — as will be seen in the following pages. The second or lower SERIES of plants — called cryptogamous, or fiowerless — has been divided into three Classes ; in two of which, the plants have a distinct axis, or definite stem and foliage, — and in the third, there is no distinction of stem and foliage, but a mere veget- able expansion — or thallus, so called. The plants of the first of these cryptogamous Classes, consist of woody and vascular tissue, and grow only at the summit, — and are, for that reason, termed Acrogens, or Apex-growers, — embracing the Ferns, and Fern-like plants. Those of the second Class consist of cellular tissue only ; but, having a distinct foliage, and acrogenous growth, with somewhat of * Some of the Orders are so remarkably natural — i. e. the structure and more obvious features of the plants comprised by them, are so similar, — that it is often difficult to indicate good and striking characteristics, by which to distinguish the {/ewera belonging to them. This is especially true of the Families named Oruci- J'erae, Umbelliferae, and Labiatae: so much so, indeed, that each of those Orders might be regarded as a comprehensive, and yet tolerably well-defined, Genus. — This fact will enable the Student to understand why it has been found necessary, in such families, to seize upon any constant characters — however minute, or obscure— that may eenre to discriminate between closely allied Tribes and Genera. PRELIMINARY DISCOURSES. the aspect of the superior plants, they have on that account been denominated Anophytes, — comprising the Mosses and Hepaticae. The plants of the third and lowest cryptogamous Class com- posed of parenchyma alone, or mere cellular masses, or expansions, without any marked distinction of root, stem, or foliage, — are called Thallophytes. This Class consists mainly of Lichens, Fungi, and Algae, or Sea-weeds, — some of which present the simplest forms of vegetable existence. "In an exposition of the natural system, some authors (such as JUSSIEU and ENDLICHER) commence with the lower extremity of the series, and end with the higher; while others (as DE CANDOLLE) pursue the opposite course, beginning with the most perfect flower- ing plants, and concluding with the lowest grade of flowerless plants. The first mode possesses the advantage of ascending by successive steps from the simplest to the most complex structure ; the second, that of passing from the most complete and best under- stood to the most reduced and least known forms; or, in other words, from the easiest to the most difficult ; and is therefore the best plan for the student."* These very imperfect preliminary Discourses are submitted to the youthful reader in the hope, and for the simple purpose, of Commending to his favor the study of the interesting objects here- inafter described ; and in the firm belief, moreover, that such study •will prove an unfailing source of both pleasure and profit, to all Who prosecute it with success. And now — having reached the allotted limit of three score and ten — the Author would take an affectionate leave of his young * The opinion cited in the text, is that of Prof. A. GRAY. It is sustained by AUGUSTS DE SAINT-HILAIRE, in the following passage, referring to the same sub- ject:— " Devons-nous, & 1'exemple de JUSSIEU, commencer cette s6rie par les plantes les plus imparfaites, ou faut-il, comme M. DE CANDOLLE, la commencer par celles qui sont le plus elevens dans 1'ordre des developpmeuts ?

CRYPTOGAMIA. -§3~The Genera of this Class are all arranged in the Series of FLOWERLESS PLANTS ; and will be found distributed in the natural orders to which they sever- ally belong. NATURAL ARRANGEMENT OP THE GROUPS AND ORDERS IN THIS WORK. THE VEGETABLE KINGDOM is arranged, by Prof. A. GRAY in his Botanical Text Book (which arrangement is here adopted), in two Series or grand Divisions — known as Phaenogamous or Flowering Plants, and Cryptugamous or Flowerless Plants. These, again, are subdivided ; and the plants belonging to them are disposed, according to their structure and affinities, in Classes, Sub-Glasses, Divisions Groups, Orders, Sub-Orders, Tribes, Sub-Tribes, Genera, Sub-Genera, Species and Varieties. The following is a Synoptical View of the general arrangement and grouping of the Natural Orders, or Families, to which the plants enumerated in this work are referable ; which, the intelligent reader will perceive, has been derived from the valuable Text-book, above mentioned. Such a Conspectus, it is believed, may be satisfactory and useful to the Student,— as affording a comprehensive glance at the general principles, or basis of the System, upon which the superstructure of details has been erected. Under this impression it has been here inserted. SERIES I. PHAENOG'AMOUS OR FLOWERING PLANTS. PLANTS furnished with flowers (essentially consisting of stamens and pistils], and producing proper seeds. CLASS I. EXOGENOUS OR DICOTYLEDONOUS PLANTS. STEM consisting of a distinct bark and pith, which are separated by an interposed layer of woody fibre and vessels, forming wood in all perennial stems ; increase in diameter effected by the annual deposition of new layers between the old wood and the bark, which are arranged in concentric zones, and traversed by medullary rays. Leaves commonly articulated with the stem, their veins branching and reticulated. Sepals and petals, when present, more commonly in fives or fours, and very rarely in threes.

FLORAL ENVELOPES consisting generally of both calyx and corolla, with the petals mostly distinct.* ORDER I. RANUNCULACEAE. Herbs, or woody vines, with a colorless and often acrid juice; leaves usually dis- sected ; stipules none ; petals sometimes wanting, and the calyx corolla-like, hypo- gynous ; the sepals, petals, numerous stamens, and many or few (rarely single) pistils, all distinct and unconnected; seeds with firm fleshy albumen; embryo minute. This family comprises a number of plants of considerable beauty ; but few that interest the mere utilitarian. * The petals, however, will be found more or less connected, in many species of ORDER XXXIV. LEGCMINOSAE, and ORDER XL. CCCURBITACEAE. A few instances of Dialypetalous flowers occur in ORD. LIV. ERICACEAE (viz. in the Suborders, PTRO- I.EAE ftnd MONOTROPEAE), — which Order is, nevertheless, placed in the Gamopetolous Division of the Series. The petals are also nearly distinct, in some plants of ORD. LV. AQUIFOLIACEAE (Yiz. in Ilex, and Prinos); and in Chionanthus, ORD. LXXIV. OLEACEAE. 1 D SI'S ^<>- i- ??ll sill IIS, Pair.

August. Obs. This introduced plant is usually to be met with in gardens ; and occasionally finds its way into the grain-fields of thoughtless people who are in the practice of carrying garden-rubbish into the barn-yard. In such cases, it threatens to become a nuisance. TRIBE 5. CIMICIFIPGEAE. &paU colored, caducous; petals none, or small and flat (staminodia) ; pistils 1 or several ; fruit baccate, or follicular, 1- 2- or many-seeded. Leaves alternate.

Seeds flatted, packed horizontally in 2 rows. Hob. Rich woodlands : common. Fl. June. Fr. Sept. Obs. The white racemes of this plant, when in flower, are quite conspicuous in our woodlands. The stem and leaves, when bruised, have a disagreeable odor. The large root is somewhat mucilaginous and astringent ; and an infusion of it is quite a popular medicine, for both man and beast, — without much regard to the nature of the disease ! ORDER II. MAGNOLIACEAE. Trees or shrubs ; leaf -buds sheathed by membranous stipules ; leaves alternate, en- tire, or lobed (never serrate) ; flowers solitary, hypogynous, polyandrous, polygynous, usually large ; both sepals and petals colored, arranged in series of threes, imbrica- ted in the bud ; anthers long, adnate ; pistils mostly packed together, and covering the prolonged receptacle ; seeds 1 or 2 in each carpel ; albumen fleshy ; embryo minute.

Flowers white, on thick clavate peduncles, very fragrant. Hob. Swamps, and along rivulets : rare. Fl. June. Fr. Sept. Obs. This delightful little tree, though abundant in the swamps of New-Castle county, on the south of us, is rare in Chester county. MAGNOLIACEAE 9 KALM, in his Travels, -written a century since, says — "Both the Swedes and English call it Beaver tree, because the root of this tree is the dainty of Beavers, which are caught by its means." 2.

Flowers tulip- shaped, greenish-yellow, with dashes of reddish-orange. Carpels produced at^ip«x into a lance-oblong wing, and closely imbricated on the fusiform receptacle. Sab. Rich woodlands, and fence-rows : common. FL May. Fr. October. Obs. The wood of this magnificent tree is highly valued in many branches of the mechanic art, — especially the variety called yellow poplar, which is generally to be known by its thicker and more deeply furrowed bark. The bark of the root, and young tree, is a good aromatic bitter. "Many people," says KALM, "believe its roots to be as efficacious against the fever as the Jesuit's Bark." — Persons of taste are beginning to discover, that this, and some others of our splendid forest trees, are quite as worthy of cultivation, for shade and ornament, as many of the far-fetched exotics. The 'same may be said, also, of our brilliant native shrubs, — such as the Kalmias, Azaleas, &c. &c. ORDER III. ANONACEAE.

Seeds with a fleshy integument, and a solid horny albumen, deep blue at maturity. Hob. Rich woodlands : frequent. Fl. April. Fr. Aug. Obs. This curious plant was one of the numerous articles of the aboriginal materia medica, now fallen into neglect. Though nearly allied to the Leontice, of Europe, I entirely concur with Prof. A. GRAY, that it may "very probably resume its generic rank"; and have accordingly acted upon the suggestion. f f Anthers not opening by uplifted valves. 1?. PODOPHYI/L.UM. L. [Gr.

This foreigner has made its appearance, within a few years, PAPAVERACEAE 13 in some of our cultivated grounds ; and if not attended to, may be- come a troublesome weed. The P. somntferum, L, — the sleep- bringing, or Opium Poppy, is to be seen in almost every garden, and nearly naturalized. Dr. DARWIN thus notices it, in his gorgeous poem: — " Sopha'd on silk, amid her charm-built towers, Her meads of asphodel, and amaranth bowers, Where Sleep and Silence guard the soft abodes, In sullen apathy PAPAVEE nods." t f Herbs with a yellow or orange-colored juice. * Seeds pitted. 21.

This foreigner was formerly frequent among Flax, when that plant was generally cultivated ; but since that culture has de- clined, the Camelina has become more rare, within my observation. I am informed, however, by H. JONES BROOKE, Esq., of Delaware county, Pennsylvania, that it had recently become a serious nui- sance, in his wheat fields. Being an annual, the obvious remedy "Was to prevent it from maturing its seeds ; but, being contempora- neous with the crops, and mingled with them, its extirpation seemed a hopeless task. Finding his grounds getting full of this pest, Mr. BROOKE — with the practical sagacity of an intelligent observer — adopted a plan which resulted in complete success : namely, keep- ing the ground ploughed or stirred, for a year or two, so often as to prevent the ripening of new seeds, and to promote the vegetation of all the old ones in the soil. Among the vulgar errors of benighted agriculture, was the belief that this plant was a kind of transmuted or degenerate Flax, — caused by burning the soil, in clearings. TRIBE 6. LEPIDIN'EAE.

The imaginative author of the Botanic Garden thus describes this curious little plant: — "Queen of the marsh, imperial DROSERA treads Rush-fringed banks, and moss-embroidered beds; Redundant folds of glossy silk surround Her slender waist, and trail upon the ground; Five sister-nymphs collect with graceful ease, Or spread the floating purple to the breeze ; And five fair youths with duteous love comply With each soft mandate of her moving eye. As with sweet grace her snowy neck she bows, A zone of diamonds trembles round her brows; Bright shines the silver halo, as she turns ; And, as she steps, the living lustre burns." ORDER XV.

It was formerly supposed to be the cause of scabs, and cutaneous ulcers, among cattle, — especially white cows, HYPERICACEAE 29 and horses with white feet and noses. The fact was taken for granted, by the farmers: But, it must be confessed, that although the plant continues to be abundant, the disease has nearly, if not entirely, disappeared. It may be worthy of remark, that in the year 1842, the St. John's-Wort totally failed to make its appearance (in this County — and I believe throughout Pennsylvania) ;— even in fields where it had been most abundant. The succeeding year, it was quite rare ; but has since become about as common as ever, in neglected fields. Why a perennial should have been thus affected, seemed rather mysterious. 2.

Trees, or shrubby plants ; leaves alternate, with deciduous stipules ; flowers axillary, small; sepals valvate, and petals imbricated, in the bud; stamens somewhat poly- adelphous ; anthers 2-celled ; seeds albuminous. This, like the preceding, is a mucilaginous family of plants ; and some of the species are also remarkable for the texture and strength of their bark. The liber, or inner bark of the Tilias, separates readily into thin layers, or strips, which are extensively woven into matting, in the North of Europe ; and the Gunny-bags, of commerce, are manufactured from the fibrous bark of two species of Corchorus. 88 DIALYPETALOUS EXOGENS 6?.

The wood of this tree affords a good material for the manu- facture of various domestic utensils.

Nat. of Europe. Fl. June. Fr. July. Obs. This plant — once considered so indispensable among the crops of our farmers — is now rarely cultivated. The Cotton-plant, of the South, has nearly banished the Flax from this region ; though some attempts are now being made, among Manufacturers, to in- crease the use of Flax, by improving the manipulations of its fibres. The Farmers, however, will not be anxious to resume the culture ; for the crop is one which involves a good deal of disagreeable labor, — and is, moreover, believed to be injurious to the soil: an opinion as old as the time of VIRGIL — who says : " Urit enim Lini campum Seges, urit avenae." — Georg. 1. 71. or, as rendered by SOTHEBY, " Oats and the Flaxen Harvest burn the ground." Doctor DARWIN refers to the Flax, in the following strains : — " Inventress of the Woof, fair LINA flings The flying shuttle through the dancing strings; Inlays the broider'd weft with flowery dyes, Quick beat the reeds, the pedals fall and rise: Slow from the beam the lengths of warp unwind, And dance and nod the massy weights behind. Taught by her labors, from the fertile soil Immortal Isis clothed the banks of Nile ; And fair ARACHNE with her rival loom Found, undeserved, a melancholy doom." "Isiswas said to have invented spinning and weaving,— mankind before that time being clothed with the skins of animals. The fable of ARACHNE was to com- pliment this new art of spinning and weaving, supposed to surpass in fineness the web of the spider." The seeds of this plant — beside yielding a most valuable oil — afford one of the best mucilaginous drinks, for coughs, and dysen- teric affections. ORDER XXL GERANIACEAE. Herbs, or suffruticose plants, with tumid nodes ; leaves mostly opposite and palmate, lobed, stipulate; flowers symmetrical, hypogynous, pentamerous; sepals imbricated ; petals convolute; stamens 10, slightly monadelphous at base, the alternate ones shorter ; pistils 5, adhering to a central prolonged axis, from which they separate at maturity by curving up from the base ; seeds solitary, without albumen. This Order comprises, amongst others, the numerous and favorite plants, so much cultivated under the name of " Geraniums," — though they now belong to the genus Pelargonium. 69. GERANIUM, L. [Gr.

The /. jBalsamina, L. called "Lady's Slippers" — a native of India — is abundant, and almost naturalized, in every garden. The follow- ing fanciful lines, from DARWIN, probably have reference to the European species, — but may apply to all: — "With fierce distracted eye IMPATIENS stands, Swells her pale cheeks, and brandishes her hands, "With rage and hate the astonished groves alarms, And hurls her infants from her frantic arms."

Flowers pale greenish-yellow, in terminal thyrsoid panicles. Hob. Streets, and about houses. Nat. of China. Fl. June. Fr. Sept. Obs. This is not an ungraceful tree in its habit, — but a disagree- able one in its odor. It is also exceedingly troublesome in sending ' XANTHOXYLACEAK 43 np countless suckers from its wide-spreading roots. It was intro- duced as a Shade tree, about the year 1820 ; but will scarcely main- tain its position as such. I learn from WM. JACKSON, Esqr., of Harmony Grove, in this County, that the XANTHOX'YLON AMEBI- C\NUM, Mill. — (a prickly Shrub, which is the type of this Order), — has escaped from the gardens, and is becoming naturalized^, sev- eral places in that vicinity. ORDER XXVII. ANACARDIA^CEAE. Shrubs, or trees; with a resinous, or milky, acrid juice; leaves alternate, mostly compound, without stipules; flowers regular, pentandrous, small, often polygamo- dioicous ; ovary (by abortion) 1-celled, and 1-ovuled, but with three styles or stig" mas ; seeds without albumen. In the tropical regions, this Family presents plants of much interest : — such as that which yields the celebrated Mango fruit (Mangifera Indica, L.)— the Cashew JVlrf (Anacardium occidentals, L.) — and the Pistacia Nut (Pistacia vera, L.~), — with others, which afford various kinds of Lacquer, and Varnish. 75. RHITS', L. [The ancient Greek and Latin name of the genus.] Sepals 5, connected at base, persistent. Petals 5, inserted with the stamens on, or under, the edge of a flatted disk.

Stem 15 to 20 or 30 feet high, with spreading branches above.— Leaflets 2 to 4 inches long, 8 to 12 or 15 pairs and a terminal one. Flowers yel- lowish-green, in terminal thyrsoid panicles, — the fertile ones about 6 inches long, very dense, oblong and nearly cylindrical ; fruit densely clothed with a purple pubescence, which is sharply acid. Sab. Woods, and banks of streams; Schuylkill: not common. Fl. June. Fr. Sept. Obs. This is the largest and handsomest species, indigenous to the County. The fine purple clusters of fruit, on the fertile plant, render it quite an ornamental little tree ; and when planted in the yards and public squares of our cities, it affords an almost literal exemplification of the much-admired Khus in urbe ! Its roots, how- ever, are rather troublesome, in sending up suckers. * * Young branches downy-pubescent. 2. R. copallina, L.

Flowers yellowish-green, in slender race- mose axillary panicles. Fruit dry, smooth and shining, pale brown. Hob. Woods, fence-rows, &c.: frequent. Fl. May. Fr. Sept. Obs. The climbing variety (formerly regarded as a distinct species, and named R. radicans,] is much the most common, here: but some fine specimens of the erect variety were collected in the South Western part of the County, in 1841, by Mr. JOHN M'MiNN. They are both poisonous, to some persons. ORDER XXVIII. ACERA^CEAE. Trees, yielding a sweet sap; leaves opposite, without stipules; flowers polygamo- dioicous, regular but often apetalous or unsymmetrical ; fruit a pair of more or less diverging separable 1-seeded samaras, winged at summit, with the outer margin 'thicker and obtuse; seeds nearly without albumen. ?6. ACER, L. [The ancient classical name of the maple.] Sepals 5, connected at base. Petals 5, or often none. Stamens 5 to .8.

Streets, and yards. Nat. of Europe. Fl. April. Fr. Obs. This has been introduced, latterly, as an ornamental shade tree ; but I consider our own Sugar Maple, and the Norway Maple, as decidedly preferable, notwithstanding COWPER'S lines: " nor unnoted pass The Sycamore, capricious in attire, Now green, now tawny, and, ere autumn yet Have chang'd the woods, in scarlet honors bright." Both this and the Plane tree (Platanus), are vulgarly called Syca- more, in our language ; but ivhy, is not apparent. The true "Syca- more"— (perhaps the Tree which ZACCIIEUS climbed) — is a species of Fig-tree (Ficus Sycomorus, L;). jj. A. pLATANofcES, L. Lactescent ; leaves broadly cordate, 5- lobed, coarsely dentate ; flowers somewhat corymbose ; fruit divari- cate, smooth. PLATANUS-LIKE ACER. Norway Maple. A large tree, when full grown. Leaves 4 to 6 inches in length, and rather wider than long, deep shining green ; petioles about as long as the leaves, when broken exsuding a milky juice! Flowers pale greenish-yellow, in loose, terminal, and somewhat pendulous corymbs. Samaras remarkably divaricate, glabrous. Hob. Streets, &c. Nat. of Europe. Fl. April. Fr. ' f\ ' Obs. This tree has been but recently introduced ; yet it promises to become one of our most desirable shade trees. Its foliage is re- markably fine, and abundant, continuing gre.en longer than most other species ; and it is' said that its milky juice prevents the rav- ages of insects. * * Petals none. 3. A. sac c* liar i nil in, Wangenh. Leaves broad, palmately 3- to 5-lobed, the lobes acuminate, coarsely sinuate-dentate; flowers pendulous on long villous fasciculate pedicels ; fruit slightly diverg- ing, turgid, smooth. SACCHARINE ACER. Sugar Maple. Stem 60 to 80 feet, or more, in height. Leaves 3 to 5 inches long, and about as wide as long, becoming golden-yellow in autumn ; petioles 2 to 6 or 8 inches in length. Flowers pale greenish-yellow, truncate and cup-like, the border fringed with long hairs. Fruit ovoid at base, nearly parallel, rather short. Hob. Rich woodlands; along streams: rare. Fl. April. Fr. Sept. Obs. This is one of the most valuable and interesting of our rat-' tive forest trees, — especially in the North and West — whercits sap, in early spring, yields an immense quantity of Sugar and Syrup. — The beautiful wood, known as Bird's-eye Maple — so much admired in cabinet work — is believed to be aiforded by this species. The tree is also much cultivated, and deservedly admired, as an orna- mental shade tree. The A. nigrum, of MX. called Black Maple, seems now to be regarded as a mere variety of the A. saccharinum. . Its leaves, however, are usually larger and of a darker green, thicker, and somewhat coriaceous in texture. It makes even a finer shade I 46 DIALYPETALOUS EXOGENS tree than the common variety, and is cultivated for that purpose, in our villages, — though rarely met with in a wild state, here. It is said to be more common than the other, at the South. f f Flowers in short erect dusters, from lateral leafless buds, preceding the leaves. * Petals none. 4. A. dasycarpum, Ehrh.

WOOLLY-FRUITED ACER. Silver-leaved Maple. White Maple. Stem 30 to 50 or 60 feet high, much and widely branching ; the young branches virgate and rather drooping. Leaves 3 to 6 inches long, very glaucous or bluish- white beneath; petioles 2 to 6 inches long. Flowers pale green, in fascicles mostly of fives or sevens, on short pedicels ; calyx a crenately truncate cup. Samara, when mature, 2 to near 3 inches long, somewhat resembling the wing of a huge grasshopper. Hob. Banks of rivers; Schuylkill: rare. Fl. April. Fr. May. Obs. This has been extensively cultivated as a shade tree, of late, — and it has the merit of easy culture, and rapid growth ; but it is decidedly inferior (me judice] to both the Norway, and the Sugar Maple. ** Petals 5. 5, A. rub rum, L. Leaves mostly 3-lobed, subcordate at base, lobes acute, unequally incised-dentate ; ovaries smooth. RED ACER. Red Maple. Swamp Maple.

Flowers bright purple — or often yellowish-tawny — on longish pedicels. Hob. Moist, low grounds : common. Fl. March. Fr. Sept. Obs. The variety with tawny flowers (first noticed, I believe, by HUMPHRY MARSHALL), is quite frequent in Chester County, — ami those flowers are generally sterile (staminate) ; while the purple flowers, so far as I have observed, are constantly perfect and fertile. The wood of this species — especially that sort known as Curled Maple — is much esteemed in the manufacture of household furniture. TT. NTEGIIN'DO, Moenck.

This little tree is certainly distinct, in habit, from the gen- erality of Maples, — and seems to be finally separated from them, by modern Botanists; but, if a tree is to be "known by its fruit," this one will always be liable to be taken, or mistaken, for an Acer.

Leaflets sessile, 4 to 6 or 8 inches long, penninerved ; common petiole 4 to 8 inches long. Flowers white, with red spots, in large erect terminal thyrsoid panicles. Hob. Yards, and streets : cultivated. Fl. May. Fr. October. t Obs. This ornamental tree (a native of Northern India) is only now beginning to be appreciated, and to be introduced, here. In- deed, it is marvellous to reflect, how inconsiderate our people have been, until quite recently, on the subject of providing Shade trees, as a shelter from the fervid glare of our Summer's sun. It is to be hoped that owe posterity may be able to say, with more truth than we can — " Our fathers knew the value of a screen From sultry suns; and in their shaded walks And long protracted bowers, enjoyed at noon The gloom and coolness of declining day." There are several native species, in the Southern and Western States, where they bear the name of Buck-eye, from a resemblance of the seeds to the eye of that animal. These native trees, by reason of their abundance, have become the popular emblem of Ohio — which is known throughout the Union by the sobriquet of the "Buck- eye State." ORDER XXX. CELASTRACEAE.

It seems now to be agreed, on all hands, that in our climate, the only mode of securing a crop of foreign Grapes, is to cultivate them under glass. In that way, the delicious fruit may almost certain^ be obtained. f f Flowers oftenpolygamo-diaicous (Native species). 2. V. Labrusca, L. Reaves roundish-cordate, somewhat 3- lobed, densely tomentose beneath ; racemes simple ; berries large. Fox-Grape (of the Northern States; not of Virginia). Stem 15 to 20 or 30 feet long, straggling over bushes and small trees; branchlets lanuginous. Leaves 4 to 6 inches in length, — the tomentum beneath persistent, inclining to russet, or tawny ; petides 2 to 4 inches long. Flowers yellowish-green, in rather short racemes. Berries globose, about half an inch in diameter, varying at maturity from black to amber color, and sometimes greenish-white ; of a strong musky or rancid flavor. Hob. Moist thickets, along streams : frequent. Fl. June. Fr. Sept. Obs. This gi-ape is believed to be the original of those cultivated varieties (some of them possibly hybrids) known as Isabella, Schuyl- kill, Raccoon, Catawba, Alexander's, Tasker's, and Blond's grape. — They are all decided improvements upon the wild fruit ; and suc- ceed much better, in this climate, than any of the foreign ones. The Catawba grape, in particular, has yielded wine of a superior quality, in Ohio, — and is well worthy of culture as a table grape. 3. V. aestivalis, MX. Leaves broadly cordate, often 3- to 5- lobed, or sinuate-palmate, loosely tomentose beneath; racemes densely compound ; berries small. SUMMER VITIS. Little Grape. Summer Grape. I ' -Stem 20 to 40, sometimes 60 feet, or more, in length, often climbing high trees. — 'Leaves 4 to 8 inches long, with a loose cobwjeb-like russet pubescence beneath, " • *vhen young, more hirsute, — sometimes smoothish when older ; petioles 2 to 4 ' inches long, Flowers greenish, often umbellulate in the longish compound ra- cemes. Berries scarcely half the size of the preceding, deep blue or blueish-black, and covered with a glaucous powder, when mature. Hab. Woods, thickets, &c.: frequent. Fl. June. Fr. Octo. Obs. The fruit of this, when fully mature, is of a sprightly acid and agreeable flavor, — quite a favorite with those who are fond of pastry Tarts; though the nut-like seeds are rather objectionable. — Some of the varieties bear larger berries, which might probably be- come more valuable under culture. 4. V. COrdifolia, MX. Leaves cordate, acuminate, incised- dentate, smooth on both sides ; racemes slender, loosely compound ; berries small. VITACEAB 51 HEART-LEAVED VITIS. Chicken Grape. Winter Grape. Stem 10 to 20 feet long, climbing and spreading over bushes. Leaves 2 to 6 inches long, smooth and a little shining, the nerves beneath pubescent; petioles 2 to 5 inches long. Flowers greenish, in loose racemes, which often have long abortive branches at base, retrograding into tendrils. Fruit small, greenish amber color, or sometimes nearly black, when mature, very acerb. Hob. Thickets, fence-rows, &c.: frequent. FL June. Fr. NOT. Obs. This was mistaken for the V. vulpina, of Linn, until Mr. ELLIOTT suggested that the true original Fox Grape was most prob- ably what MICHAUX named V. rotundifolia ; and which is known in Virginia, and further South, by the various names of Fox Grape, Bull, or Bullet Grape, Muscadine, and Scuppernong Grape. 84.

Hob. Low grounds ; along streams : frequent. Fl. Aug. Fr. Octo. 06s. The leav es of this rather showy species afford, it is said, a tolerable substitute for the Senna of the shops, — which is another species of the same genus. Doctor DARWIN, in his Botanic Gar- den, probably refers to this one, as follows: — "Where vast Ontario rolls his brineless tides, And feeds the trackless forests on his sides, Fair CASSIA, trembling, hears the howling woods, And trusts her tawny children to the floods. Tinctured with gold, while ten fond brothers stand, And guard the beauty on her native land ; Soft breathes the gale, the current gently moves. And bears to Norway's coasts her infant loves." "This," he adds, "is one of the American fruits which are annually thrown on the coasts of Norway ; and are frequently in so recent a state as to vegetate, when properly taken care of." f f ANNUAL: anthers aU fertile; petiolar gland cup-shaped. 2.

Legumes about 2 inches long, hairy along the sutures. Hob. Hills, near Pugh-town : rare. Fl. July. Fr. Sept. Obs. In a paper, read before the American Philosophical Society, May 2, 1788, and published in the 3rd volume of their Transactions, Dr. GEEENWAY, of Virginia, speaks favorably of this plant as a means of recruiting worn out lands, by its decomposition in the soil, — though he considers the common corn-field Pea as preferable ; and I have no doubt that the red Clover (Trifolium pratense), properly managed, is more eligible than either. 3.

This fine tree has been introduced from the West ; and al- though not equal to some others, as a shade tree, is worthy of a place in all ornamental plantations.

Trees, shrubs, or herbs ; leaves alternate, stipulate ; flowers regular; stamens dis- tinct, inserted on the calyx, mostly numerous ; pistils 1 to many, free, or combined with the calyx-tube; seeds 1 or few in each ovary, without albumen; radicle straight. This Order is remarkable for the amount and variety of its esculent products. — Many of the fruits are valuable, and some of them eminently delieiotis ; while the type of the Order (Rosa) is by universal consent regarded as the Queen of Beauty, among./Zwers. A few of the drupaceous species contain a somewhat dan- gerous quantity of Prussic Add, in the nuts and leaves ; but in the Peach, for in stance, there is just enough of that formidable ingredient to give to the pulp an exquisite flavor,* — and the fleshy or succulent fruits of the Order are, almost without exception, innocent and wholesome. SUBORDER I. AMYGDAVLEAE. Trees, or sJirubs; leaves simple ; stipules free', ovary solitary, free from the decid- uous calyx, with 2 suspended collateral ovuks, and a terminal style ; fruit a drupe, mostly 1-seeded by abortion. f Nut with the surface rugosdy furrowed. HO. PER'SICA, Tournef. [A name derived from Persia, — its native country.] Calyx tubular, with 5 spreading segments. Drupe oval, tomentose or smooth, the succulent pulp adherent, or separable from the nut. Small trees : leaves oblong-lanceolate, serrate, conduplicate in the bud ; flowers solitary or in pairs, subsessile, preceding the leaves. 1. P. VULG\RIS, Mill. Fruit densely tomentose. COMMON PERSIC A. Peach. Peach-tree. Stem 8 to 12 or 15 feet high, branching. Leaves 3 to 5 or 6 inches long; petioles about half an inch in length, channelled above, and glandular near the leaf. — Flowers pale-red or purplish. Drupe 1 to 2 inches, or more, in diameter, with the pulp white, yellow, or reddish, adherent to the nut (clingstone), or separable from it (freestone). * Judging from observation, it would seem to be not generally known to our Pastry Cooks, that a Peach Pie baked with the fruit whoU (i. e. simply pared, but the nut left in the Peach) is vastly superior to one made of the mere fleshy portion, cut in pieces. The process of baking— &s I suppose— elicits the prussic acid from the seed of the peach, and diffuses it through the pulp, — imparting to it a sprightly and delicious flavor, far beyond what it possesses when the stone is previously rejected. KOSACEAE 71 Hob. Yards, gardens, and orchards. Nat. of Persia. Fl. April. Fr. Aug. Obs. The fruit of this tree — like the most of those which have had the advantage of long and careful culture — presents numerous varieties; the best of which may be pronounced (mejudice] superior to all other known fruits. The tree, unfortunately, is short-lived ; but it is readily propagated from seeds, — and a succession may be kept up by inserting upon young stocks, buds, or scions, taken from the most approved varieties* This process, for changing the char- acter of seedling trees, is alluded to by the great English Bard with his usual felicity: — " You see, we marry A gentler scion to the wildest stock; And make conceive a bark of baser kind By bud of nobler race : This is an art Which does mend natilre, — change it rather: but The art itself is nature."

This small tree is scarcely to be distinguished from the pre- ceding, except by its smooth fruit, — which presents the same varie- ties, of clingstone and freestone. Prof. DE CANDOLLE admits it as a distinct species ; but it is certainly very closely allied to the Peach, — and, indeed, there are instances recorded, in which the same tree is said to have produced both varieties. The crop of fruit is much more certain under glass, with the branches trained on espaliers. f f Nut i6ith the, surface smooth and even. 111. ARMEtfIAvCA, Tournef. [A name derived from Armenia, — its native Country.] Calyx campanulate, the 5 segments reflexed. Drupe roundish-oval, velvety-pubescent; nut compressed, one edge obtuse, the other acute. Small trees: leaves subcordate or ovate, convolute in the bud ; flowers white, solitary, or few from a bud, preceding the leaves. 1. A. VULGARIS, Lam. Leaves orbicular-ovate, shortly acuminate, serrate-dentate ; flowers sessile. COMMON ARMENIACA. Apricot. Moor-park Apricot. Stem 10 to 15 or 20 feet high, with lather stout spreading or straggling branches. Leaves about 3 inches long, and rather wider than long; petioles an inch or inch and half in length, mostly with cup-like glands near the base of the leaf. Drupes oval, about an inch in diameter, yellowish when mature. Hob. Yards, and gardens. Nat. of Armenia. Fl. April. Fr. July. Obs. The name of this fruit, in SHAKSPEARE'S time, was written " Apricocks" (perhaps by a corruption of the latin, A. praecox — meaning Early Armeniaca), — as We may perceive in the following lines: — " Go bind thou up yon' dangling Apricocks, Which, like unruly children, make their sire Stoop with oppression of their prodigal weight." King Rithard IT. This is an admired fruit ; and might be much more common than 72 DIALYPETALOUS EXOGEXS ' ;-...."--.^jfc it now is, if people were a little more attentive to such matters. — Indeed, it is melancholy to reflect how thoughtless and negligent mankind generally are, with respect to providing fruit for themselves. There are few persons who do not own or occupy sufficient ground to admit of 3 or 4 choice fruit-trees, and a grape vine ; — such, for instance, as an Apricot, a Peach, a May-duke Cherry, a Catharine Pear, and a Catawba Grape: yet the great majority seem never to think of planting such trees, — while they are ready enough to in- vade the premises, and revel on the fruits, of some more provident neighbor ! It is due to the minor morals of the community, that such disreputable negligence, and such marauding practices, should cease to be tolerated, 2. A. DASYcXuFA, Pers. Leaves ovate or oval, acute, doubly ser- rate ; flowers pedicellate. HAIRY-FRUITED ARMENIACA. Black Apricot. Stem 10 to 15 feet high, with rather slender branches, and a spreading bushy top.

Drupes globose, red or yellowish-red, nearly or quite destitute of bloom, with a tender pulp and a thin skin. Hub. Yards, and gardens. Fl. April. Fr. July. Obs. This little tree (which is believed to be a native of our South- Western territory, — where it is a small shrub, in its wild state,) by long culture produces a very pleasant fruit, — worthy of more attention than it has yet received. It approaches the Cherry in character and appearance, and may be considered as a connecting link between the Plum and Cherry; but it is unquestionably, I think, a true Plum. Why MICHAUX'S specific name was permitted to supersede MARSHALL'S (viz. angustifolia), which was published long before, I do not understand. 113. CER'ASIJS, Tournef. [The name of an Asiatic town, — whence the tree was obtained.] Flower nearly as in Prunus : drupe globular or roundish-ovoid, often umbilicate at base, glabrous, destitute of bloom; nut globose. — Trees, or shrubs: leaves conduplicate in the bud; pedicels of the flowers either in umbellate fascicles from lateral leafless buds, and then rather preceding the leaves,- — or in racemes terminating leafy branches, and coming after the leaves ; petals white. f Flowers in naked lateral fascicles, preceding the leaves. 1.

Drupes of various size and color, tender, and often very succulent, sweet, or bitterish-sweet, Hob. About houses; along fence-rows, &c. Fl. April. Fr. June. Obs. Cherries are said to have been originally brought to Rome from Cerasus, a city of Pontus, by the Roman Consul and General, LUCULLTJS, some 60 or 70 years before the Christian era (ab urbe conditd' 680. Willd.}; and from Rome they have been distributed over the rest of the civilized world. Our cultivated Cherry trees seem obviously to consist of at least two original species, — viz. the sweet "English Cherry" so called — and the common Sour Cherry. The numerous varieties — produced by long culture (and possibly some hybrids, such as the "May-duke" &c.) — may perhaps be all referred to one or the other of those two ; though Prof. DE CAN- DOLLE distributes them iniofour species. There are, undoubtedly, several very distinct sorts of fruit, — and I have not seen all the trees which produce them : but I incline to think that the general habit and aspect of the trees -commonly seen in this country, warrant the reduction of them all to the two above referred to. 3. C. VuLGXms, Mill. Branches spreading, slender and flexible; leaves lance-ovate and obovate, acute or acuminate, mostly narrowed at base, serrate, smoothish ; drupes globose. COMMON CERASUS. Red or Sour Cherry. Morello Cherry, &c. Stem 10 to 20 feet high, irregularly branched ; branches rather slender and flaccid, spreading nearly horizontally and forming a roundish bushy top. Leaves 1% to 3 inches long; petioles half an inch to an inch in length. Pedicels of the flowers about as long as the petioles, 2, or more frequently 3, in a fascicle. Drupes fleshy, more or less acid, red or dark purple when mature. Sab. Fence-rows; along lanes, &c. FL April. Fr. July. Obs. The "Sour Cherry'* is the most common and, for culinary purposes, the most valuable of the genus. The Morello Cherry is a remarkably fine variety, with a rich purple juice,— and in the days of " Cherry Bounce," was a great favorite: But, for the last 30 years, it has almost entirely failed, in this region, — in consequence, apparently, of the ravages of an insect, causing large warty excres- cences on the branches of the tree. f f Flowers in racemes at the end of leafy branches. 4.

The wood of this species is a pale reddish-brown, close- grained and hard — taking a good polish ; and was formerly much used by cabinet-makers. The bark — though a rather unpalatable bitter— 4s a good tonic. The leaves are a favorite food of caterpil- lars ; and the ripe fruit is greedily devoured by birds. SUBORDER II. ROSAVCEAE PROPER.

The P. simplex, of Authors, with slender ascending stems, and taller growth — frequent along the borders of open woodlands, and in clearings — is doubtless very properly reduced to a variety of this. The prevalence of the plant, in arable lands, is a pretty sure indication of a thin soil, or of a thriftless farmer, — or both ; though some lands, when kept as pasture fields, seem to have an almost incurable tendency to lose the valuable grasses, and to become speedily overrun with Cinque-foil. Lime and manure, however — if duly persevered with — will work wonders in the poorest soils. 120. FRAGAVRIA, Tournef.

Long and careful culture of this species (which is very nearly allied to the preceding, and said to be truly indigenous) has resulted in numerous fine varieties, differing in the size, color, and flavor of the receptacles ; and has also produced many abortive or i BOSACEAE 79 imperfect flowers, — which have given rise to much idle controversy about their sexual character, among the practical gardeners. — Although the true fruit of this plant consists of mere dry specks, or bony particles (i. e. the minute akenes), scattered over the surface of the enlarged receptacle, — yet the receptacle itself furnishes a pulpy substitute of the most delicious character. 121.

This Thorn — so familiar to us, in the Poetry of England — •was formerly rather frequent in Chester County, and partially nat- uralized; but is now becoming rare.

This species is the one which has been chiefly cultivated for hedging, in this County, — where it was introduced, from the vicinity of Washington City, about the commencement of the present cen- tury. It makes a handsome hedge, when well managed ; but not so substantial and effective as the Cockspur Thorn. It is so subject to be injured, and broken into gaps, by thoughtless and reckless trespassers — especially near villages — that the attempt to cultivate it is rather a source of vexation, than of satisfaction. * * Fruit middle-size.] 3» C.

Fence-rows; thickets, &c.: not common. .FZ.June. Fr. Octo. 06*. There appears to be two pretty distinct varieties of this; both of which, however, are so rare, that I am not quite sure they are truly indigenous here. The Cock-spur Thorn, in my judgment, is decidedly the best for making a durable and effective hedge : But, until timber shall become scarce, very few farmers will take the requisite pains to insure a complete hedge, — and without such care, it is worse than labor lost to make the attempt. In the lan- guage of Mr. M'MAHON'S excellent " American Gardener's Calendar" referring to the hedging experiments of negligent, slovenly farmers : " I would advise such to hold fast by the post and rail, and not to lose time in doing more harm than good." * * * Fruit rather large. 4.

He adds, that, in the very year when he was writing, "there were many in France, and some in England, who underwent an enchantment without any divining rod at all, and be- lieved themselves to be affected by an invisible agent, which the Enchanter called Animal Magnetism!" ORDER XXXIX. GROSSULACEAE.

Seeds with a dry membranous arillus. ^ Obs. The firm woody shell, of the fruit, affords a convenient kitchen utensil, — for which the plant is cultivated, by cottagers and farmers who cannot afford, or do not choose, to purchase more costly ones. WILLDENOW seems to have had a high opinion of its value, in domestic economy. Under the head of Usus, he mentions "Lagenae, Cochlearia, Infundibula, Pilei, innumeraque Utensilia." It might serve all these purposes, in a primitive state of society ; but our people have generally got rather past that. There is occasion- ally cultivated, for the table, a cucurbitaceous fruit of extraordinary length, called " vegetable marrow," — which seems to belong to this species, and may, perhaps, be the variety clavata, of SERINGE and DE CANDOLLE. 137.

Hairy. Stem 8 to 12 or 15 feet long, angular, somewhat branching. Leaves 3 to 5 or 6 inches long, ovate in their outline; petioles 2 to 3 inches in length, gener- ally erect. Fruit 10 to 20 inches long, with a firm fleshy rind, and, when mature, with a tender sweet watery frosty-looking or crystalized pulp within, which is usually purplish or reddish-orange color. Seeds black, or purplish brown. Hab. Gardens, Ac. Nat. of India and Africa. Fl. June. Fr. Aug. Obs. There is a nearly allied plant, often seen in gardens, which bears a different /rmZ — known by the name of " Citron," — the firm rind of which is used in making sweetmeats, or "Preserves." The interior is also firm, and does not become red, tender and watery, like the common Water Melon : yet the whole aspect of the plant, and external appearance of the fruit, so closely resemble this species, that I suppose it may be nothing more than a variety, — perhaps the Var. Pasteca, of SERINGE and DE CANDOLLE. 139. SICTOS, L. [The ancient Greek name of the Cucumber.] Calyx campanulate.

Fruit compressed, ovate, in stellately-globose heads, which are about an inch in diameter, and armed with slender tawny spines. Hob. Banks of Schuylkill : rare. Fl. July. Fr. Sept. Obs. This Cucumber-like Vine has found its way into some gar- dens ; where it is something of a nuisance, and rather difficult to get rid of.

UMBELLIF'ERAE. Herbs; flowers in (usually involucrate) umbels; calyx-tube entirely adherent to the ovary ; petals 5 ; stamens 5, inserted (alternately) with the petals, on the disk that crowns the ovary and surrounds the base of the 2 styles; fruit consisting of 2 seed-like dry carpels;* seeds solitary, suspended; embryo minute, in the apex of copious horny albumen. Stems usually hollow ; leaves alternate, generally much dissected, exstipulate, but the petioles more or less dilated and sheathing at base. The plants of this Order are much less numerous in our country, than in the old world. Of the 28 species here described, 9 have been introduced, — and of these, 6 or 7 are cultivated. * The carpels of the umbelliferae are usually marked with a definite number of longitudinal ribs, which are sometimes dilated into wings; the intervals, or chan- nels, between the ribs — as also the commissure (or face, by which the carpels are joined) — often contain one or more linear receptacles of aromatic oil, — which re- ceptacles are called vittae, or fillets. Those ribs on the carpels, are distinguished into primary, and secondary. The primary ones (10 in number on the 2 carpels — or 5 on each,) are pretty constant, and more or less conspicuous, — representing the midribs and sutures of the 5 sepals, which, by their union, form the tube of the calyx and coating of the fruit. The 5 ribs which answer to the midribs of the sepals, are termed carinal ribs, and their extension at apex forms the 5 calyx- teeth. Alternating with these primary ribs, there is sometimes a development of secondary ones, — which Prof. DE CANDOLLE regards as representing lateral nerves (i. e. one on each side of the midrib) of the sepals. The ribs and vittae — together with the form, or manner of compression, of the fruit — afford important aid in de- termining the generic character of the plants of this remarkably natural family : and consequently, the student, or young herborizer, should always bear in minti that it is requisite to have specimens of umbettiferae with full-grown fruit.

This is a Comparatively harmless native weed, — frequent in shaded places about dwellings: But, there is a foreigner, with some- thing of its general habit and aspect (viz. Aegopbdium Podagrtiria, L.), which has been introduced into some lots and gardens, in Ger- mantown, near Philadelphia, — and proves to be a nuisance, not easily abated. It has hitherto resisted all attempts to get rid of it ; and Sir J. E. SMITH, in his Flora Britannica, says of it — "radix rcpcns. vix exstirpanda." In DON'S General System of Gardening and Botany, it is also remarked pf the Aegopodium, that "being a great creeper, it cannot be admitted into gardens, for after it gets hold it is next to impossible to eradicate it again." P. COLLINSON, writing to JOHN BARTRAM, says, "it is a notorious running weed in the gar- den." A plant of such character (and worthless beside,) deserves to be studied, and watched that it may be avoided. 162. A'PIIJM, L.

Involucre about 3 inches in diameter, when expanded, —the leaves in opposite pairs, sessile, white and petal-like, sometimes tinged with purple. Flowers greenish-yellow. Hob. Woodlands : very common. Fl. May. Fr. Septem. Obs. The wood of this small tree is very close-grained and firm, and valuable for many purposes in mechanics. Cabinet-makers sometimes employ it, in the manufacture of small articles of furni- ture,— in which, my friend Dr. ELWYN assures me, it is very beauti- ful. The woodman selects it as the best material for wooden wedges. The young straight stems make good hoops, for the cooper; and the slender verticillate branches once furnished distaffs for Spinsters, — in the "good old times," when that description of females had a prac- tical existence in the community. The bark is an excellent tonic, — almost rivaling the Cinchona, in efficacy. A century since, accord- ing to KALM, there was so much faith in the virtues of the Dogwood, that "when the cattle fall down in spring, for want of strength, the people tie a branch of this tree on their neck, thinking it will help them !" Altogether — and without any joke — it is a valuable as well as ornamental little tree, — worthy of a place in lawns and yards. — Observing farmers have remarked, that the proper time to plant Indian Corn (Zea Mays, L.) is when the involucres of the Dogwood are first developed. 112 GAMOPETALOUS EXOGENS DIVISION II. GAMOPET'ALOUS EXOGENOUS PLANTS. FLORAL ENVELOPES usually consisting of both calyx and corolla, — the petals more or less united.* ORDER XLVII. CAPRIFOLIAVCEAE.

Flowers in verticils of about 6, in the axils of the upper connate leaves ; corolla externally red or purplish, the limb at first nearly white, soon becoming tawny yellow, — the tube an inch or more in length, tapering to the base, and somewhat resembling a Cornucopia, smooth within. Stamens ex- serted, about equalling the style. Berries orange red, at maturity. Hah. Moist, rocky woods ; along streams : not common. Fl. May. Fr. July. Obs. This species bears considerable resemblance to the common cultivated species (L. Caprifblium, L.), — though the flowers have a rather stronger and less agreeable odor. Honeysuckles have always been favorite plants, for decorating arbors, and porticos; and are much frequented by the exquisitely beautiful little Humming-bird. They are thus alluded to, by SHAKSPEARE : — " And bid her steal into the pleached bower, Where Honeysuckles, lipen'd by the sun, Forbid the sun to enter ; — like favorites, Made proud by Princes, that advance their pride Against that power that bred it." * Some instances of dialypetalous flowers occur in this Division, in ORDER LIV. ERICACEAE (viz : in the genus Clethra, and Suborders, PYROLEAE and MONOTROPE^). The petols are also nearly distinct, in the genera Ilex and Prinos, of the ORDERLY. AQUIFOLIACE^. The plants belonging to ORDER XL. CUCURBITACE^ although often gamopetalous, •will be found in the dialypetaloos division; also some of the ORDER XXXIV. LEGU- MINOSJE, — as in Trifolium, &c. Our native species of Fraxinus — belonging to ORDER LXXIV. OLEAC&E, and arranged at the end of the GAMOPETAJLE— are destitute of petals. CAPR1FOLIACEAE 113 Doctor DARWIN, also, refers to the delightful genus, in the fol- lowing lines: — " Fair LOMCERA prints the dewy lawn, And decks with brighter blush the vermil dawn ; Winds round the shadowy rocks, and pansied vales, And scents with sweeter breath the summer gales ; With artless grace and native ease she charms, And bears the horn of plenty in her arms." 2. ]j. parviflora, Lam.

The slender stems of this shrub, when the pith is removed, afford good fuse-sticks, for blasting rocks ; and are much used for that purpose. A species of this genus, commonly cultivated as an ornamental shrub, is the Guelder-Eose, or "Snow-ball" ( F. Opulus, £.), _ which the Poet COWPER so beautifully describes, as throwing up its - " silver globes, light as the foamy surf, That the wind severs from the broken wave." ORDER XLVIII. RUBIACEAE.

This execrable foreign weed has found its way into our County, but is happily yet rare ; and it behooves every good citizen to extirpate it, wherever it may appear. Some years since, the authorities of on.e of our cities — where it was becoming a great nuisance, in the streets — enacted an ordinance against the plant, — denouncing it by the name of Canada Thistle! The misnomer probably did not impair the efficacy of the ordinance : But it would be more reputable to all concerned, if they could avoid confounding objects which are essentially distinct, — -and learn to designate even weeds by their proper names.

This showy, but worthless, and prevalent weed, is said to have been sent from Wales, as a garden flower, to a Mr. Ranstead, of Philadelphia. JOHN BARTRAM, writing of the troublesome plants, in Pennsylvania, near a century since, says — "The most mischiev- ous of these, is the stinking yellow Linaria. It is the most hurtful plant to our pastures that can grow in our northern climate. Neith- er the spade, plough, nor hoe, can eradicate it, when it is spread in a pasture. Every little fibre that is left, will soon increase prodigi- ously; nay, some people have rolled great heaps of logs upon it, and burnt them to ashes, whereby the earth was burnt half a foot deep, yet it put up again, as fresh as ever, covering the ground so close as not to let any grass grow amongst it; and -the cattle can't abide it," This is rather stronger testimony than I am prepared to bear against the plant ; but it is certainly a monopolizing and most unwelcome intruder, on our farms, — and requires persevering efforts to get rid of it. Specimens of that remarkable form of the flower, known by the name of Peloria — with a regular 5-lobed corolla, 5 spurs, and 5 perfect stamens — are occasionally to be met with. — They are frequently, if not always, late flowers, — situated at the summit of the raceme of full-grown capsules, and apparently the latest floral developments of the plant. Sometimes these Pelorias are tetranierous ; i. e. the corolla is 4-lobed, with 4 spurs, and 4 stamens.

Obs. The infusion of this herb is a popular and pleasant bever- age, in fevers. In the beginning of winter, after a rain, very curious ribbands of ice may often be observed, attached to the base of the stems, — produced, I presume, by the moisture from the earth rising in the dead stems by capillary attraction, and then being gradually forced out horizontally, through a slit, by the process of freezing. The same phenomenon has been observed in other plants. See obs. on Helianthemum, p. 27» b. Fertile stamens 4, more or less didynamous. 28?. PYCtfAtf'THEMUM, MX. [Gr.

This plant — which became known to Europeans about the year 1560 — though sparingly cultivated in Chester County, is a staple article among the Planters of several Southern and Western States. The commercial importance which this nauseous and pow- erful narcotic has acquired, — together with the modes, and extent, in which it is employed to gratify the senses, — certainly constitutes one of the most remarkable traits in the history of civilized man. — Were we not so practically familiar with the business, we should, doubtless, be disposed to regard the whole story of the Tobacco trade — and of the uses made of the disgusting herb — as an absurd and extravagant fable. In view of the facts and circumstances, it does seem like sheer affectation, on our part, to pretend to be as- tonished at the indulgence of the Chinese, and other Asiatics, in the use of Opium. The habitual use of Tobacco is always more or less injurious to the system — especially the nervous system; and in many instances it is highly deleterious. I speak from long ob- servation, and personal experience, — having smoked and chewed the herb, until its pernicious effects compelled me to es-chew it altogether. 325. DATITRA, L.

The variety, Tatula — with dark purple stems, and purplish flowers, — is the one which prevails in Chester County ; though the other is common in and around Philadelphia, — and is gradually extending in this direction. It is generally put down as a native of America ; but I strongly suspect it is of Asiatic origin, — and am very confident it is a stranger in this region. The herb, and seeds, are powerfully narcotic poisons, — and therefore, no doubt, potent medicines, when properly administered ; but the plant is regarded, and treated, as an obnoxious weed, by all neat farmers. tf Corolla campanvlate, or rotate ; stamens connivent; fruit a berry. * AnUiors opening longitudinally. 15 226 GAMOPETALOUS EXOGENS 3'16. 1VICAHFDRA, Adans.

It is, however, rather abundant in New Jersey,— and frequent, also, in the adjoining States of Delaware and Maryland. Doctor DARWIN thus refers to the Mistletoe, in his imaginative Poem: — " Oh ! stay, bright habitant of air, alight, Celestial VISCA, from thy angel-flight!— Scorning the sordid soil, aloft she springs, Shakes her white plume, and claps her golden wings; High o'er the fields of boundless ether roves, And seeks amid the clouds her soaring loves!"

There is also one of large size, — with larger and coarser leaves, — which has been taken for C. crassifolia, of LAMARCK ; but that species does not appear to be very distinctly denned. Perhaps they may both be nothing more than varieties of C. occidentalis. ORDER LXXXVI. SAURURACEAE.

It appears, by the correspondence of PETER COLLINSON with JOHN BARTRAM, more than a century since, that this plant was then known by the name of Aristolochia, — probably from the resemblance of its leaves to those of the Virginia Snake-root ; and that the bruised rhizoma was regarded as a salutary application to sore breasts, — an opinion which prevails among the good ladies, who deal in simples, at this day.

This plant presents some varieties, which are doubtless pro- duced by the circumstances of their locality, — especially one which is often seen, prostrate and radicating, in muddy places from which the water has retired ; but I am not sure that we have more than one species.

This belongs to a notable tribe of inert medicinal plants, which — once in an age, or so — dabblers in quackery have the address to impose upon the credulous, as being endowed with marvellous virtues, in incurable or desperate stages of disease. Some years ago, — after Anagallis, and Scutellaria, had become rather obsolete, as Newspaper cures for that terrible malady, Hydrophobia, — the Alisma was proclaimed, through the Gazettes, as a certain remedy; and persons who ventured to express a doubt, were scarcely tolera- ted, by the editorial fraternity ! This specific, however, soon shared the fate of its predecessors ; and will probably be no more heard of, until a future race of Empirics, in the cycle of "Progress," shall again bring it forward.

I have never met with the staminate plant. Dr. GRAY says, "the staminate clusters being confined to the bottom of the water "by the shortness of the scape, the flower-buds themselves spontane- ously break away from their short pedicels and float on the surface, where they expand and shed their pollen around the fertile flowers, which are raised to the surface at this time." The fertile scapes then "coil spirally and draw the ovary under water to ripen." — WILSON, in his Ornithology, says the root is a favorite food of the Canvass-back Duck, — to which the peculiarly delicate flavor of the flesh of that bird has been ascribed. The bunches of long dark- green leaves, which are usually procumbently floating, afford a hiding-place for Eels, — whence one of its common names. In refer- ence to this plant, Dr. DARWIN indulges in the following imagina- tive strains : — " As dash the waves on India's breezy strand, Her flush'd cheek press'd upon her lily hand, VALUSNER sits, upturns her tearful eyes, Calls her lost lover, and upbraids the skies ; Tor him she breathes the silent sigh, forlorn, Each setting day ; for him each rising morn :— HYDROCHARIDACEAE 307 Bright orhs, that light yon high ethereal plain, Or batfce your radiant tresses in the main; Pale moon, that eilver'st o'er night's sable brow ; For ye were witness to his parting vow ! Ye shelving rocks, dark waves, and sounding shore,— Ye echoed sweet the tender words he swore ! — Can stars or seas the sails of love retain? 0 ! guide my wanderer to my arms again ! " My excellent Friend, E. I>URAND, has sent me the following Lines by a French Poet and Botanist, which may be appropriately annexed to the preceding : — " Le Rhdne impgtueux, sous son onde Scumante, Durant six mois entiers nous derobe une plante Dont la tige s'allonge en la saison d'amour, Monte au dessus des flots et brille aux yeux du jour. Les males dans le fond jusqu'alors immobiles, De leurs liens trop courts brisent les noeuds debiles, Toguent vers leur amante, et libres dans leurs feux, Lui forment sur le fleuve un cortege nombreux : On diralt une fete ou le dieu d'hym6nee Promene sur les flots sa pompe fortunSe ; Mais les temps de Venus une fois accomplis, La tige se retire en rapprochant ses plis, Et va murir sous 1'eau sa sentence feconde." — ORDER CV.

This foreigner has escaped from the gardens, in many places, — and although it perfects but few seeds, it multiplies its bulbs so rapidly, as to be a great annoyance to the tidy farmer. The bulbs of this species are said to be much used for food, in the Levant; and LINNAEUS imagined them to be the "Dove's Dung," which was sold so dear at the siege of Samaria, as mentioned in the 2nd book of Kings, Chap. VI. (See HOOKER & ABNOTT'S British Flora). Some of our Agriculturists could furnish almost any quan- tity,— and, I imagine, would gladly part with them, at a very low price! 44*2. AI/UUM, L.

It is now completely naturalized, — and, in some districts, so abundant as to be quite a nuisance.

Three of the anthers are completely abortive and cross-shaped, — and a fourth one is partially so modified, or in process of metamorphosis to that state. The authorities all appear to concur in calling the plant a perennial : but I-am much mistaken if the one with us is not an annual. It was accidentally introduced to this Borough, about thirty years since, from the Garden of the late JOHN JACKSON, of London Grove; and is gradually extending itself.

TRUE GRASSES: chiefly herbaceous; often cespitose; rhizomas slender, creeping, ramifying, with filiform radicles ; culms terete, nodose and leafy, mostly hollow between the nodes; leaves entire, with parallel nerves, distichously alternate, apparently sessile, — the petioles being dilated, and sheathing the culm, but slit on the side opposite the lamina, or blade, down to their origin at the nodes (i. e. their margins are not united, as in the Cyperaceae) ; stipules axillary, adnate to the petiole, with the scarious summit often free, and known as the ligule; flowers perfect, polygamous, or monoicous (rarely dioicous), in little spikelets at the ends GBAMINEAB 355 of the branches, and these spikelets disposed in loose panicles, or condensed into racemes, or spikes ; spikelets 1- 2- or many-flowered, formed of distichously imbri- cated chaffy bracts (stunted or modified sheaths of abortive leaves)*,— of which the outer, or lower ones, are called glumes, and the two that immediately inclose each floret are termed paleae (the inner, or upper palm usually 2-ribbed, and supposed to consist of 2 united paleae) ; proper perianth none ; stamens 1 to 6, or more — usually 3 ; anthers versatile ; ovary 1-celled, 1-ovuled, — usually with 2 minute fleshy scales at base, somewhat analogous to the bristles or hairs (perigynium), in the Cyperaceae ; styles or stigmas 2, plumose, or pencil-form, mostly with simple hairs ; fruit a seed-like grain (called a caryopsis), free, or sometimes adherent to the paleae, — the pericarp thin, and for the most part closely adnate to the seed ; embryo at the base, and on the outside, of copious farinaceous albumen. This vast Order is probably the most generally diffused, and the most important to Man, of all the families of plants.

A very rough, white-panicled grass, — common along slug- gish streams ; rather a nuisance, than otherwise. * The glumes and paleae (or what is called Chaff) of the Grasses are the crowded vestiges of the sheaths of leaves. The awns, often found on the paleae, are the midribs, or slender remains of the laminae, or blades of the leaves ; and when these awns are apparently inserted more or less distant from the apex of the paleae (or dorsal, as it is termed), it is probably owing to the extension and per sistency of the ligult of the sheath,— which ligule thus becomes a portion of the paleae. 356 ENDOGENOUS PLANTS ».

This varies greatly, in size and appearance, when growing in different soils and situations. It is believed to be a foreigner ; but is thoroughly naturalized. In our best soils, the radical leaves are very luxuriant, — when it is known by the name of "Green- Grass." It is the profusion of the nutritious radical leaves, which constitutes the chief excellence of this grass, — which is, indeed, the most valuable known in our pastures.

This species is also thoroughly naturalized, and is universally known, here, by the name of Blue-grass, — though, in Kentucky, that name is given to the preceding (our Green- Grass). It affords much less pasture than the Green-Grass, — and therefore is less valuable; but what there is, is believed to be even more nutritious. The rhizomas are exceedingly tenacious of life, — which renders the grass rather troublesome, in cultivated grounds, among other crops. 486. ERAGROS'TIS, Beauvois. [Perhaps from the Gr.

Any one, however, who has had an opportunity to observe the uniformity and constancy of the Laws which govern the development of living bodies, and yet persists in believing in the transmutation of genera and species, may be fairly placed in the category of him who be- lieves in equivocal generation, — of whom it is said, in the Amoenitates Academicae, "certe fungum habet pro cerebro." 3.

Nat. of Southern America. Ft. July. Fr. Sept. Obs. Long culture has produced several varieties of this noble Grass, — with grains of differant form and color. There is also a remarkable vanity— fre^nt, I believe, in the South west — in which a kind of hu^k, or involucre, is developed around every grain, or sp'kelet, on the receptac'e. The Goethean theory of the modification of leaves, at the successive stages of the vegetable progress, from cotyledons to flowers, is well illustrated by the envelope, or " husk," of an Etr of Indian Corn. Few heedless observers would be apt to recognize the fact, that the several portions of that envelope are the sheaths of abortive leaves : and yet nothing is more obvious, when we examine them by the light of that theory. The spike of pistil- late flowers is supported on a short axillary branch, with numerous nodes, and very short internodes. As nodes are the points at which leaves originate, we accordingly find a leaf — or rather the sheathing petiole of an imperfect one^-at each node of this short flowering- branch ; and as the nodes are very close together, the sheaths necessarily over-lap one another,— and thus furnish a manifold wrapper to the spike of flowers and fruit (i. e. the "Ear"). That these several layers of the envelope are the sheathing portions of abortive leaves, is demonstrated by the laminae, more or less de- veloped, at their summits, — and which, indeed, are sometimes seen expanded to nearly half the size of an ordinary full-grown blade. — The sam3 doctrine applies to the chaff, or floral coverings, of all the Grasses;* as it does, in fact, to those of all the flowering tribes. 507.

Calyptra, circumscissed at base ; fruit terminal, or lateral ; lid opening elastically, or sometimes indehiscent ; orifice of the capsule naked, or more commonly with aperistome; columetta manifest. DIVISION I. ACROCAKPI : Pedicel or fruitstalk terminal. * For the Mosses and Hepaticae of Chester — so far as they are yet known — I am indebted to my friend THOMAS P. JAMES, of Philadelphia, — an acute and zealous Bryologist, who (as his other engagements permitted,) has diligently explored the ANOPHTTES of our ancient Bailiwick ; and has, morever, prepared and presented to the CJiester County Cabinet of Natural Science, an elegant Collection of those in- teresting little plants. The intelligent reader will perceive that the descriptions are chiefly derived from the Contributions of that eminent Botanist, WILLIAM S. SULIJVANT, Esq. to GRAY'S MANUAL. t The reproductive organs of the MOSSES are of two kinds:—"!. The sterile flower , consisting of numerous (4 — 20) minute cylindrical sacs (antheridia), which dis- charge from their apex a mucous fluid filled with oval particles, and then perish. 2. The fertile flower, composed of numerous (4—20) flask-like bodies (pistittidid), each having a membranous covering (calyptra), terminated by a long cylindrical funnel-mouthed tube (style). The ripened pistillidium (seldom more than one in a flower maturing,) becomes the capsule, which is rarely iudehiscent, or splitting by 4 longitudinal slits, but usually opens by a lid (operculum) : beneath the lid, and arising from the mouth of the capsule, are commonly either one or two rows of rigid processes (collectively the peristome), which are always some multiple of 4; those of the outer row are called teeth — of the inner, cilia. An elastic ring of cells (annules) lies between the rim of the capsules and operculum. The powdery particles filling the capsule are spores. The thread-like stalk (pedicel, or seta,) supporting the capsule is inserted into the elongated torus (vaginula) of the flower. The pedicel continued through the capsule forms the columella; enlarged under the capsule it sometimes forms an apophysis. The calyptra, separating early at its base, is carried up on the apex of the capsule ; if it splits on one side it is hood-shaped or cuculliform, — if not, it is mitre-shaped or mitriform. Intermixed with the reproductive organs are cellular jointed filaments (paraphyses). The leaves surrounding the antheridia are called the perigonial leaves, those around the pistillidia or pedicel the perichaetial leaves."— GRAY'S Manual. 404 ANOPHTTES TRIBE 1. PHASCAVCEAE. 528.

ORDER CXXV. LICHENES. PERENNIAL plants, often spreading over the surface of the earth, or of rocks, or trees, in the form of a lobed and foliaceous, or hard and crustaceous, or leprous *The Chester County Plants of this obscure Class have been investigated with singular diligence and success, by my ingenious friend EZRA MICHENER, M. D. to whose kindness I am indebted for the following account of them ; the Lichens being arranged in conformity with the excellent work of EDWARD TUCKERMAN, A. M. 432 THALLOPHYTES substance, called a thattus.* Some beautiful and valuable Dyes are affor Jed by plants belonging to this order. *Tbe following definitions, and cbaracteristic details, are from TUCKEKMAN'S valuable Synojisis: — " Perennial, aerial Algae, vegetating only under the influence of moisture, which is imbibed by the whole surface, propagated by spores (sporidia), and also by the cells (gonidia) of the green layer. Thallus (universal receptacle, Ach.) composed of three layers, viz : the cortical, the medullary, and the gonimous ; evolved from a hypothallus (the elementary state in which the layers are confused, and discernible afterwards as cylindrical cells, and also as fibres on the under side of foliaceous Lichenes, and forming the base, closely adnate to the matrix, in crustaceous ones), typically horizontal or vertical. The horizontal thallus is either crustaceous (often somewhat lobed at the circumference or squamulose). or foliaceous (becoming sometimes in degenerate states crustaceous). The vertical thallus is either compressed (sub foliaceous), or terete (fruticulosR) ; of both of which the filamentous thallus and the pendulous thallus are degenerations. In Cladouia and Stereocaulon a vertical thallug (podetium) arises from the primary horizontal thallus, and is itself often be- sprinkled with a kind of secondary horizontal thallus in the form of leaf-like scales. Lichenes are reproduced in two ways; 1. by gonidia, the (normally green) cells of the green (gonimous) layer, which appear on the surface as irregularly shaped powdery masses (soredia), and propagate either on the original thallus, forming foliaceous or squamulose expansions, — or external to the original thallus, forming new individuals of the parent thallus; and 2. by sporidia, consisting of subglo- bose or elliptical cells, which are either naked or contained in other elongated more or less vertical cells (asci), and immersed in the thalamium (or fructification proper), and propagate new individuals of the species. The thalamium is either rounded, gelatinous-waxy, and the asci converging (nuclei form), — or flattened at length into a rigid, persistent, or afterward collapsing lamina (subdisciform), — or originally disciform (open) ; and is itself contained in a receptacle (exciple), either of the same color with and like the thallus (thalline exciple), or of different color and nature (proper exciple). The whole fructification constitutes the apothecium, which is typically round, though also occurring normally oblong and linear (lirellaeform,) and is either excavated with a contracted margin (urceolate), — or slightly concave with an elevated margin (scutettaeform), — or very concave-scutellaeform (cyalhi- form), — or very concave-scutellaeform and pervious (infundibuliform, — a term applied also to the pervious cup-bearing podetia of Cladoniae), — or goblet-shaped and stipitate (crateriform), — or dilated, flat, and without prominent margin (peltaeform, of which the reniform is a variation). — or convex with repressed mar- gin (cephaloid), — or between scutellaeform and peltaeform (disciform), — or between gcutellaeform and cephaloid (tuberculate). When the thalline exciple is prolonged below into a footstalk, it is said to be pedicellate ; a proper exciple in like manner prolonged is said to be stipitate. When the proper exciple is originally and typi- cally closed, the apothecium receives the name of perithecium. In the ANGIOCARPI, several thalamia are sometimes contained in the same exciple (composite apothecia) ; and in the GYMNOCARPI, in like manner, several disks are sometimes confluent (symphycarpeous apothecia). The colors of the thallus in Lichens are disposed by I'RIES In four series: — 1. from pale green becoming glaucous; 2. from yellowish green becoming ochroleucous ; 3. from dark green becoming fuscous or olivaceous ; 4. from pale yellow-green becoming lemon -colored. Each series has its peculiar variation.". The glaucous runs into pale green, ceruleseent, and white; the fuscous into dark green, olivaceous, cinereous, greyish-fuscous, and dark chestnut; the ochroleucous into yellowish green and albescent; the lemon-colored into pale yellow, orange-red, and vermilion-red."

We probably have all these allied forms. This Lichen is noted, as constituting the principal food of the Rein-deer, in Lapland. "It is this," says Sir W. J. HOOKER, "which for the greater part of the year, and especially in winter, is the support of the vast herds of Rein-deer, — wherein consists all the wealth of the Lap- landers. No vegetable, LINNAEUS tells us, grows throughout Lapland in such abundance as this, — especially in woods of scattered pines, where for very many miles together, the surface of the sterile soil is covered with it, as with snow. On the destruction of forests by fire, when no other vegetable will find nutriment, this Lichen springs up and flourishes, and, after a few years, acquires its full size. Here the Rein-deer are pastured ; and whatever may be the depth of snow, during the long winters of that climate, these crea- tures have the power of penetrating it, and obtaining their necessary food."

This genus furnishes the celebrated " Tripe de roche" (Tripe of the Rocks), of the Canadian and Western Hunters,— to which they are often obliged to resort, when other means of subsistence fail. When pro- perly prepared for the table, it is said to be a tolerable substitute lor "Tripe," — which it also somewhat resembles. 6O4. OPE'GRAPHA, Humb. [Or.
