BY Edward Lee Greene No. 1870 CITY OF WASHINGTON PUBLISHED BY THE SMITHSONIAN*INSTITUTION 1909 ADVERTISEMENT The present paper by Dr. Edward Lee Greene, Associate in Botany in the U. S. National Museum, entitled ''Landmarks of Botanical History," discusses certain epochs in the develop- ment of the science of botany. The subject is viewed from a philosophical rather than an industrial standpoint, and the author gives prominence to the biography of some of the early botanists, including Theophrastus (B.C. 370-286), and Brunfelsius, Fuchsius, Tragus, and Cordus of{the fifteenth and sixteenth centuries. Doc- tor Greene has in preparation further contributions on this general subject. CHARLES D. WALCOTT, Secretary, Smithsonian Institution. WASHINGTON, November, 1909.

VALERIUS CORDUS, 1515-1544 270 INDEX 315 PREFACE ANY discussion, or any indication even, of landmarks in the history of botany must needs be preceded by a somewhat careful enquiry into the nature and purposes of the science as such. Where- in does botany, as a science, essentially consist ? With this question unanswered it were impracticable either to indicate the origin or trace the progress of it. In the most extended use of the term, all information about the plant world or any part of it is botany. According to this view, all treatises upon agriculture, horticulture, floriculture, forestry, and pharmacy, in so far as they deal with plants and their products, are botanical. What many will consider a better use of the term is more re- stricted. In this use of it there will be excluded from the category of the properly botanical whatever has no bearing on the philosophy of plant life and form. For example, that wheat, rice, and maize agree together as to that anatomical structure which is called endogenous would be a fact of purely botanical interest. Quite as clearly such would be the proposition that all three belong to the natural family of the grasses; or this, that each represents a genus; or that the roots in all these plants are fibrous, and of only annual duration. But if it be said that wheat, rice, and maize as food products are of supreme importance to mankind, the affirmation is as completely unbotanical as the several foregoing are per- fectly botanical. It is strictly an economical consideration. If such a distinction between botany and plant industry as I have sought thus to illustrate be received as legitimate, the province of botany is easily circumscribed and its scope clearly definable. In any event, for the purposes of the present work our definition of this science shall be that it occupies itself with the contemplation of plant as related to plant, and with the whole vegetable kingdom as viewed philosophically — not economically or commercially — in its relation to the mineral on the one hand, and to the animal on the other. Such a distinguishing between the philosophical study of plants 7 8 PREFACE and the industrial does not dispute, but rather establishes, the ex- istence of a wide border domain between science and industrial art where botanist and industralist work side by side upon plant subjects; it may be sympathizingly and intercommunicatively, or it may be ignoring each other's presence; a domain within which nevertheless each should be in touch with the other, because each may, and ought to be helpful to the other, as supplying some data useless for his own purposes but of significance in relation to the other's aims. The recognition of this border-land domain illustrates also, if it does not again directly argue, the distinctness of the two realms of botany and plant industry. Here one may observe that the distinction itself would seem less marked if he who is to set himself to the work of an economic or industrial botanist would first of all equip himself with a knowledge of the principles, and cultivate an interest in the aims, of philosophic and scientific botany; so that the industrial botanist as author might always have two reports to make upon any piece of research, one that should be of economic interest, the other one of interest botanical. It may be that this idea will be found to presuppose the conjunction of the philosophic bent of mind with the industrial; a combination of two qualities of mind as rare in the world as genius itself, and less desirable. In quest, therefore, of a starting point — a first landmark — in the progress of botany, in my understanding of the science, one may pass those authors by who professedly treat of plants from the utilitarian point of view, whether they write of agriculture, horticulture, or of the materia medica. Passing these by, I say, though by no means as not meriting the botanist's attention ; for all matters relating to the qualities of plants naturally interest him, unless he be of that school in power a century ago, but now declining in influence, according to whose teachings nothing but dry morphology was of any import. Moreover, to him who, like the farmer, the woodsman, and the primitive pharmacist, has much to do with plants industrially, philosophic ideas may occur about the vegetable kingdom as a whole or in part; and every such idea, though crude, perhaps even erroneous, is a concept essentially botanical. Quite as perfectly so is the distinguishing of different kinds of plants, and the practice of grouping like kinds together under one common (generic) name, which is not only universal, but even a necessity, with those who, like the farmer and gardener, have much to do with a considerable number of plants of different sorts. People following these occupations have actually a system- PREFACE Q atic botany, with a nomenclature, families, genera, and species, all their own. So then if, in the search for a possibly early botanical landmark, the writers upon farming, gardening, and medicine are to be passed by without serious consideration, it is not because no traces of genuine botany occur in them; it is because we are in search of him with whom the leading idea is that of a philosophy of plant life and form. The first botanist is the first man who under- takes research upon plants as plants rather than as things useful or deleterious to man and beast; and the first landmark in the his- tory of botany is the earliest book in which plants and plant organs are discussed each in relation to others. If there is any attempt to distinguish and define plant organs, or any suggestions about the probable functions of any of them, any indications of how plants may be distinguished from minerals on the one hand, and from animals on the other, any attempts to correlate plants as like and unlike, and that upon some recognized prin- ciples— in any and all such endeavors, we recognize the acti- vities of a philosophic mind in its attempts to solve problems not economic but scientific. In the author of any such treatise upon plants, however imperfect or even crude his notions may seem to us, we have nevertheless the author to whom belongs the name of botanist, as in the vocabulary of the sciences that name ought to be defined. What is here undertaken is not a history of botany. There is no purpose of presenting in chronological succession the long line of the contributors to the upbuilding of this science, with an account of the best contributions each has made. That would be the work of a lifetime; indeed, of two lifetimes; for the history of no science can be made out, and presented in its perspective, but by him who first of all has mastered that science itself, in its completeness ; and the domain of botany however philosophically restricted remains vast, insomuch that one lifetime seems requisite to the mastery of it in its several departments. A second lifetime should, then, be given to him who should be required to write its history. And still the presentation of a complete and accurate history of botany would remain impossible. Important data are wanting, and hopelessly so. For one example, more than twro millenniums ago a highly philosophic and very extensive treatise upon plants was indited which alone among books of its kind has survived the pass- ing of all the centuries. The author of it cites other authors on the same topic whose books, then extant, are long since lost. This writer had also in early life a very illustrious teacher who instructed 10 PREFACE him orally in botany among other subjects, and who also wrote two- volumes of botany both of which passed into oblivion more than two thousand years since. How much, then, of the Theophrastan botany is that author's own? What of its principles are his only as having been imparted to him by his great friend and tutor Aristotle? What passages of the work are but compiled from writ- ings of a more remote antiquity, with which Theophrastus may have been familiar, of which even the authors' names have perished? Questions like these serve but to admonish one of this, that the earliest beginnings of the science do not admit of discovery. The same is in a measure true of comparatively recent periods. The annals of our science, as gathered in hitherto, reveal no more thrilling epoch than that of the sixteenth century. Some of the best known authors of that period, Brunfels, Tragus, Fuchsius, stud- ied, besides the not so very many printed books about plants that were then extant, numbers of old mediaeval manuscripts from which they brought forth and quoted many a botanical idea, several of them well advanced beyond the ideas of the ancients as we know them. No annalist of a later age seems to have had time or disposition to ascertain how much of the assumed new and original botany of those German fathers — so they style them — was taken out of old mediaeval manuscripts which, although they may still be extant, later historians have neither consulted nor troubled themselves to enquire after. Contemporarily with those German herbalists there flourished in Italy a learned professor, first at the University of Padua, then at Bologna, afterwards at Pisa, whom people regarded as the one peerless botanist of the time. His university lectures were received as oracular, and students came to him from almost everywhere in Europe; yet Professor Luca Ghini published nothing. His supremacy as botanist of the first half of the sixteenth century is attested by tradition only. In the very next generation after him, several of the chief luminaries of the science were men whom he had trained, and to one of them, Cesalpino, there is now everywhere accorded the praise of having created the epoch of modern botany. To what extent is Cesalpino's great work, De Plant is, a product of the mind of Ghini? The question is one that forces itself upon us and is perhaps the more interesting because hopeless of ever being answered. Such are a few examples of what the annalist who would be just and truthful will often find himself in need of knowing, yet can never ascertain; and they intimate but too pointedly the impossibility of PREFACE II any such thing as a complete and faithful history of any period when once that period is past. It was as realizing this, and also as wishing to avoid presumptuousness, that the present writer declined to undertake a history of botany and chose the title of " Landmarks " as permitting him to evade the responsibilities of the consecutive historian, and leaving him free to bring into clearer light — and especially for study on the part of American botanists— the lives and teachings of those and those only among botanists of the past whose names are more familiar. This plan bears on its face the appearance of an easier task, and such it really is ; though that it is a less responsible undertaking may be doubted; lor in this case quite as in the other, one must everywhere investigate individual merit, which is less apt to exist in proportion to a man's great contemporaneous popularity than in the inverse ratio of it. It will indeed be found to have happened now and then that the genius who has discovered principles has also elucidated them, ap- plied them to the construction of a system, and gained for himself and his principles the credit and the honor that were due; but perhaps rather more commonly the genius discovering prin- ciples has but quietly made the simple announcement of them, has died scarcely honored, and has been almost forgotten, when some other, just far enough above mediocrity to see the value of the principles, and possessing industry and ambition to bring them forth and build on them the system which the principles themselves suggest, gets the credit of the whole, is thought to have created the epoch, and enjoys the fame. But the annalist who leaves all these things as he finds them, reiterating popular laudation of the parasitic propagandist, and burying inventive genius yet more deeply in oblivion, deplorably falsifies history. Quite as little does he de- serve the name of historian if his mistakes in this regard be those of ignorance; if they come of his having failed to discover merit because of its having lain under the pall of forgetfulness for a cen- tury or two. The historian who is both conscientious and discreet will give small heed to popular opinion about any particular man or epoch. Neither the adulation of the multitude is of any profound import, nor its voiceless indifference. Its outspoken opposition and de- nunciation may even be the highest praise. Such being any writer's estimate of popular opinion regarding botanical eras past, his readers will be surprised neither by chapters that are icono- clastic, nor by such paragraphs as reveal immortal honors due to men whose names had almost faded from the roll of fame. 12 PREFACE It has seemed to me desirable that,, in the tracing of these outlines of botanical history some prominence ought to be given to biography. The reader or the student of a book can never take the deepest possible interest in it so long as its author is unknown to him, or, as it might be said, known by name only; though that is but an empty phrase; for to know a person by name only is not to know him at all. A fair knowledge of the whole career, early and late, of the author of a literary or scientific masterpiece not only in- tensifies, as I said, one's interest in the work, but is most helpful to the understanding of it, if not indispensable to the full compre- hension of it. To this natural and reasonable demand on the part of those who would like to learn something of the history of botany, the historians have not well responded. In most cases they give in a single paragraph, or even in a short foot-note, the year of a man's birth, that of his demise, perhaps the name of the institution whence he had his degree, and of those in which he occupied a professor's chair, and so ends the biography of a man who may have been a genius and the creator of an epoch in science ; mere epitaphic statements, which seem only to bury more deeply out of sight the once living and active personality, and to relegate his very name to a still remoter place in the region of myth and shadow. There are probably few botanists of this twentieth century who have the most vague conception of what a single one of the earlier master builders of our science was like in his personality and character. To most of us they are too nearly mythical, and mayhap less livingly pictured in our minds than are some of those really mythological personages that men believed in four thousand years ago. It will be seen that in these studies of the landmarks, I give some prominence to the biographic aspect of botanical history. This has been done at great expenditure of time and thought ; but I have felt that the end wras an extremely desirable one; and I have little or no doubt that these sketches of the lives of great promoters of our science who lived in other centuries will be received by many as among the most welcome and instructive of my paragraphs. UNITED STATES NATIONAL MUSEUM. Washington, D.C. 2 July, 1907- Landmarks of Botanical History By EDWARD LEE GREENE ^7TRODUCTORY PHILOSOPHY OF BOTANICAL HISTORY ANY history, in order that it shall merit well the name and an- swer the requirements, must have its definite philosophy. History presupposes some end awaiting attainment, and in itself it would seem to be a well connected record of the thoughts, the words, and the deeds that have either furthered or hindered the attainment of that end. It does not, however, assume that the actual makers of history recognize the ultimate end. That is something which not even the wisest can foresee otherwise than dimly and with much uncertainty. The aim of the science of botany, for example, being the fullest and most perfectly systematized knowledge of the plant world philosophically considered, it still is true that not one in a hundred among the rank and file of real contributors to- ward this ultimate purpose has had it definitely in view. The great bulk of botanical work hitherto accomplished has been done in detached pieces, and by such as had only proximate ends before their mental vision. And for the very best of research work no more is needed. He who carefully investigates and puts on record the whole life history of a dandelion or of a violet; who gives the whole anatomy of a few mosses, reeds, or sedges, or indicates the morphologic distinctions between the pollen grains of hollyhock and those of thistles, or traces the development of either one; who brings out the philosophy of the twining of a morning-glory stem, or indicates the organogeny or the functions of the stipules of vetch and pea; or he who after years of critical field study catalogues, with original notes and observations, the flowering plants — or the 13 14 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 fiowerless ones — of a single county, or of the watershed of any lake or stream, every such laborer contributes to the stock of botanical knowledge, and this without reference to personal con- prehensiveness of botanical view, or a looking to far off ultimate ends. Upon the historian of botany, however, it seems to devolve that he shall have some forecast of what botany in its perfection as a science shall be like; for in practice he sits in judgment on each epoch and decides whether as an epoch its tendency was more to the advancement of the science than to its retardation; from which kind of procedure it becomes certain that some ideal of perfection is in his mind. Every writer on botanical history must have his philosophy of that history, unless he content himself and hope to satisfy his readers with disconnected historic frag- ments. It may be useful to survey in this connection, though with the utmost brevity, the methods of several representative historians of botany. Tournefort (1700), eminent among even the greatest promoters of botany, was also its historian. The first fifty pages of his Institutiones1 are occupied with an abridged history of the science during two thousand years preceding his own date. The history is prefaced by a definition. There are two parts to botany: the knowledge of plants, and the knowledge of the uses (vertus) of them. It is a distinguishing between systematic botany and economic. He says the distinction must be carefully noted. He denies to the properties or uses of plants any part in, or influence upon, the systematizing of them. A systematized presentation of the known facts constitutes the first beginning of every science. There can be absolutely no botany at all without systematic botany. These are Tournefort's ground principles. From them we shall gather his philosophy of the advancement of botany. The plant world can never come to be well known until sounder prin- ciples of classification shall have been established, and the whole aggregate of known plants shall have been grouped over again upon those better principles. The long line of the most noted authors before him had classified plants in all kinds of ways, some according to characters of the roots, some by differences of stems and leaves, one^by fruits alone, another by the qualities and uses of the plants; another grouping them according to their places of growth, or ecologically, as we now say. Seldom were the systems of any two 1 Institutions Rei Herbaria, Paris, 1700. LANDMARKS OF BOTANICAL HISTORY GREENE iq authors at even approximate agreement. Often that of an indi- vidual author was a compound of inconsistencies, utterly inhar- monious within itself. As to that very first necessity of botany, rational system, confusion seemed to reign. The flower was an organ hitherto little studied, and scarcely yet appealed to in the art or science of plant grouping. Two or three botanists of a century earlier than Tournefort had suggested that, after all, not in roots or stems or leaves, but in the flower there might per- chance be found the key to a more satisfactory method of plant classifying. He undertook now a new systematization of the world of plants, everywhere appealing to anthology in so far as by the presence of flowers and fruits the appeal was possible. Ceasing to take as criteria the qualities of plants, or even the characters of their vegetative organs, and by giving special and close study to both flowers and fruits instead, with judicious co-ordination and use of the characters of both, will botanical system henceforward obtain best furtherance. With neither the strong points nor the weak ones in Tournefort's system, nor with its success or failure, are we here concerned. All that will engage us now is his conception of botany as a science in process of further development and improvement; in other words, what he would have taken to be the leading philosophic threads of botanical history. They would probably be two, at least as chiefly conspicuous ; for during his career his mind had been much occupied with (i) the thought that better and more firmly established generic groups had been the most crying need of botany from the earliest times, and (2) that such more acceptable and more securely estab- lished genera would result from the defining of them according to morphology of flower and fruit, the consideration of vegetative organs being omitted as far as possible. So then, from his own outlook over the past of botany and from his best forecasting of its future, they have helped it forward most who have most contri- buted to a better anthology and carpology, and such obtain with him foremost places in his epitome of botanical history. The fullest credit is given to all botanical travellers to distant shores who have contributed to the enrichment of botanical gardens, and to the making of illustrated folios representing flowers and fruits of plants alien and rare. Meanwhile how small consideration Tournefort accorded to plant anatomy and physiology is evinced by this, that in his history he has not a line to spare for the names of Grew and Malpighi, great promoters though they were of the cause of plant organography in general, and well entitled to rank l6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54. among creative botanists. We may chance to find historians of less comprehensiveness of view than Tournefort, and some with greater. Two generations later a countryman of his, Michel Adanson, sketched less succinctly than Tournefort had done the history of botany. It forms the more important part of a voluminous pre- face to Adanson's Families des Plantes. 1 Eighty-five years after its first publication this History was reprinted, with many augmenta- tions which the author had left in manuscript at the time his death.2 A man whom all nature in her every phase attracted and en- gaged, but still first and last and always a botanist, Adanson's horizon was a broad one. He was also a botanist with a specialty, that of discovering how genera naturally stand together in larger groups that may be called families. On the whole, and if such dis- tinction be allowed as legitimate, he was a systematic botanist; most pronouncedly such. But the sketch that he gives of the history of botany is neither partial nor one-sided. He reviews the science as having progressed along many lines, not one of them unimportant. But since it is families of plants that he is now to treat of at length, the foremost thought in his mind in the writing of a history of botany as a preface to the book is, that he may demon- strate the early rise and tardy progress of this very idea of plant families. It is not, however, the history of that one aspect of botany merely that he writes. Something a little too near the one-idea history was what Tournefort had presented; even as one may to-day say of the latest of all the historians of our science, that he came rather too near to excluding from very thoughtful consid- eration almost everything except the history of plant anatomy and physiology, and of the taxonomy of the cryptogams. Adanson appears to have realized that no one part of botany is alienable from • any other part ; that the history of a part of it can not be written as disconnected from that of the other parts; and therefore, con- nectedly with the presentation of whatever had been done before his time towards a natural correlating or grouping of genera, he brings into view not only that line, but others along which botany has made progress ; paying due respect to every kind of effort that makes for a fuller knowledge of the plant world. With the main purpose, then, of finding early traces of the re- cognition of something like natural families, Adanson analyzes 1 Families des Plantes, Paris, 1763, Partie I.

LANDMARKS OF BOTANICAL HISTORY GREENE I 7 briefly and in chronological succession more than sixty leading au- thors, beginning with Theophrastus and ending with some who have been contemporary with himself in the middle of the eigh- teenth century. Assuming that these analyses are correct, one may read connectedly, with small sacrifice of time and as it were step by step the progress which, up to Adanson's time, had been made in the grouping of genera into families — or whatever else one may choose to call such groups; and, while it will be regarded an im- portant one among several threads that the philosophical and im- partial historian is bound to follow I know not who besides Adanson has ever attempted to trace this one except for a very short distance.1 And the next thread of botanical story which Adanson picks up and follows is one that lies close alongside the aforementioned. The earlier endeavors to indicate groups of genera were made an- teriorly to the time when structure of flower and fruit had come to be accepted as the guide. By what marks did those pioneers of classification guide themselves in their attempted groupings? By way of answer I give a short selection from Adanson's own more detailed report of the matter. Lobel (1570), he says was guided by general resemblances, size, qualities, and uses; Porta (1588), by ecology, forms of roots, of leaves, and vegetative organs generally; J. Bauhin (1650), has 40 classes, by appeal to all organs, as well as to properties of plants and their ecology; Rivinus (1690), in- florescence, calyx, and corolla; Boerhaave (1710), general aspects, ecology, leaves, fruits; Haller (1742), cotyledons, calyx, corolla, stamens, seeds; Gleditsch (1749), flowers, insertion of stamens; and so on through a list of some sixty writers, each a celebrity in his day as the author of some new attempt at system in botany.2 Of a situation like this, and one so necessary to be brought forward in any history of the science, Sachs knewnothing, neither even Sprengel. There is another outlook upon the progress of botany that is almost peculiarly Adanson's. At the beginning of the analysis of each author's treatise he notifies us how many different kinds of plants each man knew, or had under discussion in his book — Theo- phrastus 500, Hermann 5600, Tournefort 10,146, Ray 18,655, as examples — thus recognizing at every step the important considera- tion that, other things being equal, the greater the number of plant 1 Linnaeus in his Classes Plantarum accomplished this admirably for a very limited period, that is, for the time between 1583 and 1738; only a small fraction of the time during which the idea of classes, or families, had been in the minds of botanists and found more or less distinct expression. 2 Adanson, Families, vol. i, pp. Ixxxix-xciii. l8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 forms a man knows, the safer his conclusions as to the interrelations of all, or of the members of any group of them. Of course the specialist in plant anatomy, little interested in the whole chain of plant relationships — he to whom 500 species were enough for his own purposes — may chance not to be in sympathy with these searchings of all corners of the earth for new plants. 1 But to what comprehension of the whole of botany has such a mind attained? It would have something like its parallel in the astronomer, if such astronomer there had been, who had deprecated the labor involved in the discovery of the planets Uranus and Nep- tune upon the plea that there was already enough to do with the rings of Saturn and the canals of Mars. At least somewhat like that is the attitude of the historian who makes light of the work of plant discovery and plant description. To ascertain, as Adanson was at the pains of doing, what number of species a given systemat- ist had known, was the only possible way of informing himself of the comprehensiveness of the man's view of things. And as to the ideal and ultimate perfection of knowledge of the vegetable kingdom, that is manifestly impossible of attainment, so long as a single type, either living or fossil, remains undiscovered and undescribed. It is a principle which not only justifies, but, in the interests of the science as viewed without partiality or prejudice and compre- hensively, imperatively demands the most thorough exploration of every field, the equipment of the best possible botanic gardens and herbaria, and also the highest possible perfection of the art of phytography, that is, plant diagnosis or description. Of incalculable usefulness to the student of systematization is phytography. Its purpose is that of enabling the botanist to measurably complete his knowledge of this and that group of plants only some proportion of the species of which he has been able to see, inspect, and study in the living state. All that a man may learn about plants in twenty years of field work, supplemented by all that gardens and herbaria have to show, will not amount to the knowledge of any more than a fractional part of the specific mem- bership of as much as one of the many families or considerable genera of higher plants. For the rounding out of his knowledge —general, even superficial knowledge— of whatsoever plant alliance, one is always dependent on descriptions. It is one of the most important conditions of all general botany ; one that was fully recognized at the beginning ; also one that will forever remain. It has always been and it will always be, that a good plant description, placed before i Sachs, Geschichte, pp. 42, 43- English edition, pp. 39, 40- ' LANDMARKS OF BOTANICAL HISTORY — GREENE 19 one mentally equipped for the exact interpretation of it. is decidedly more satisfactory than the usual herbarium fragment of a plant. Yet one word as to correct and incorrect phytography. One who has a new plant in hand, and who knows it thoroughly from root to seed, may use the whole of an octavo page and the half of another in what will be supposed to have been an attempt to picture this type in words. This same plant may be much more distinctly pictured to the mind of the trained and habituated phytographer in one-fourth that space or even less, by using the set terminology of descriptive botany. This was invented for the two- fold purpose of saving space and increasing perspicuity in plant definition. In its most nearly perfected state it is quite modern; and the history of this terminology is a very significant part of botanical history. The discovery of each term was, in its day, a distinctly botanical discovery and an important one ; yet the Spren- gels and Sachses have given rarely a hint of the evolution of ter- minology. To have made out lucidly its history would have been a heavy tax on precious time. Adanson almost alone, it may be said, has not neglected it. It was seen by him that in a well de- vised scheme of botanical history an account of the development of descriptive terminology and the art of describing should find place. Accordingly in these mere outlines for such history he charges certain authors with having described plants poorly; others he remarks upon as having described them fairly, while to here and there he gives the praise of having described them well. One must not pursue further the subject of Adanson's topical divisions. Those presented may suffice for what I wished to il- lustrate, namely his appreciation of what ought to enter into the making of a history of botany. Synoptically placed, those few of his topics of which I make mention are : 1 . History of grouping of genera as classes or families. 2. History of accepted criteria of affinity. 3. Progress in discovery of new types. 4. Development of phytography and its terminology. This mere beginning of Adanson's scheme of history will enable me to indicate the contrast that subsists between his and that of Sprengel, whose not unpretentious work in two volumes was given to the public one year after Adanson's death.1 Out of the four Adansonian topics named above, only one, the third, obtains good treatment at the hands of Sprengel. The first and second are blank with him; while under the fourth one may gather little beyond » C. Sprengel, Historia Rei Herbariae, Amsterdam, 1808, 2 vols., 8vo. 20 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 some salient points in the history of anthology. Anatomy and physiology are so discussed as if not inseparably connected with botany proper. Indeed in his partitioning of the science into the two compartments of the Systematic and Structural he expresses his mind to the effect that while Botany proper is a part of Natural History, the consideration of the inner structure and physiology of plants belongs rather to Physiology.1 His treatment of these, as developed in the course of the seventeenth century is nevertheless full and explicit. But it is progress in the disco very of new types, history of botanical exploration at home and abroad, and the enrichment of botanical gardens, which more particularly engage Sprengel; and, as Adanson had been more interested in the de- velopment of the idea of plant families, Sprengel, as a devoted Linnaean, gives himself to the investigation of the history of genera and species. All the long way from Theophrastus to Linnaeus Sprengel lists new types generic and specific as discovered and published by prominent authors ; so that a fair chronological history of at least the European Flora is furnished ; and these lists of each man's discoveries form so large a part of the body of his work that its principal index is an idex of genera and species. There is no need of pursuing beyond this brief initiative our examination into the somewhat diverse philosophies of botanical history that have hitherto found expression. Every one may be permitted to have his own. In the present treatise exception will be taken to one assumption made by all earlier historians, that for the earliest intimations of anything looking in the direction of the science of botany we must have recourse to those oldest pieces of literature in which plants are more or less freely mentioned. Adanson, for example, does not begin botanical history without naming Orpheus, Musa, Solomon, Hesiod, Homer, Metrodorus, and Hippocrates who as poets or as physicians wrote of plants. Spren- gel has among his initial chapters one bearing the title "Flora Biblica" another "Flora Homerica, " another, "Flora Hippocra- tica " ; and these chapters of Sprengel are botany, even very interest- ing botany2 ; but this is not saying that there is botany in the Sacred Scriptures, or in the poems of Homer, or in the medical writings of Hippocrates. They are, however, classic texts upon which a man of Spren gel's rare accomplishments may write botany. And yet I seem to apprehend certain rudiments of a science of botany in those ancient pieces of literature, the real substance of which those 1 Sprengel, Hist. Rei Herb., vol. i, p. 3. 1 Ibid,, vol. i, pp. 6-4Q. LANDMARKS OF BDTANICAL HISTORY GREENE 21 authors of botanical commentary on the Bible, on Homer, on Vergil, and the classics generally, have completely overlooked. Let me repeat it, that in several pieces of very old literature there are legible traces of a science of botany; traces of which even learned and botanically instructed commentators seem to have failed to take due note. Here, let any reader who has supposed that certain sciences had their beginnings in the minds ot men who wrote books, banish, if possible, that idea. No opinion ever held by a multitude of people was more groundless. If, according to the definitions given by authorities, science is classified knowledge and classification is the process of distinguishing and separating between things like and unlike .then there are certain of our sciences the earliest rudiments of which are almost among the very necessities of human speech. It will not be easy to imagine a tribe of wandering savages on any continent or in any age unused to the distinctions of plain, hill, mountain, or spring, brook, river, lake, and ocean. Their very languages will show that their mind had wrought out these per- fectly solid and immovable foundations of the science of Geography. Long subsequently the man of enlightenment, he who knows how to commit thought to writing, takes this old and hitherto unwritten classification of the diversities of the earth's surface, gives it logical statement, dignifies it with the Greek name Geography, and then proceeds to build as on very old yet firm foundations his nobler edifice. He may or may not recognize it that those indispensable group names, plain and mountain, lake and river, are but a heritage to his scientific geography from a very far off antiquity; from an antiquity the history of which neither has been written, nor ever will be. It were well, however, that the geographer should perceive it that the real first beginnings of his science are not with the author of any book, but that they antedate all writing. Botany, as certainly as geography, had its initiative in primal man's distinguishings and separatings between objects appertaining to the world of plants. The fact that in the rudest and simplest dialects of primitive peoples there exist group names for botanical entities establishes this. It is improbable that there ever was a primitive language, other than that of some arctic tribe, in which there did not occur words equivalent to tree, bush, grass, or to trunk, branch, leaf, fruit, root; and every one of these is the name, not of an indi- vidual object, but of a group of like objects. Each is a general — a generic — name, and each testifies most clearly to observation, comparison, reflection, generalization, and also either the invention 22 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 of a new word, or else the more extended application of an old one, which, in as far as sciencs is concerned amounts to the same thing. It is possible to trace to a time that lies well within the period of modern botany the first detection and first naming of that kind of organ which we call a stipule ; but no one will have the hardihood to propose that we may trace to its first employment the term leaf. Yet this term, which one may never hope to trace to its origin, is as strictly botanical as the later term stipule, and more important. Furthermore, there was a time when the very term leaf — or at least its equivalent in some lost language of a primal race — first came into use. And still further, the mental processes by which a Malpighi arrives at the distinguishing between the stipule and the other parts of the leaf, and those by which the unknown primal investigator came to distinguish between leaf and the stem or branch that bears it, are the same. Neither was more nor less scientific than the other. Each equally with the other had done a piece of strictly botanical research. This is not affirming equality of intelligence for the two, or questioning that he of the later time was capable of solving many problems of plant life impossible of solution by him of the earlier era. Also the motives leading to examination and distinguishing may have been quite different: he of the more recent period was actuated it may have been by that scientific curiosity, that mere zeal for knowledge, which often fires the cultivated mind; he of the primeval time was impelled per- haps by sheer necessity. He is much dependent on the plant world for life's comforts, even for its necessities. One part of a tree is of great use to him for one purpose, another part for a very different purpose, a third being of no use. Therefore from his utilitarian point of view it becomes manifestly needful that the different parts of plants be distinguished and each different part named. Language demands the introduction of such terms. But the mental pro- cesses, I repeat it, are the same in either case, and without respect to the actuating motive. It is all work of examining, comparing, distinguishing, segregating, and naming the segregates. Every step in the procedure of either is scientific. If one is tributary to a science of botany, so is the other. And if these reflections seem to indicate that scientific botany may be, as to its first elements, older than all literature, what of it? There is but one point of view from which it will be disputed, namely that which regards man as having made his first appearance on earth in a condition of advanced intelligence, with a well-developed language, and also bearing a divine commission to assign names to all manner of natural LANDMARKS OF BOTANICAL HISTORY GREENE 23 objects at first sight.1 When one notes the perfect silence of the historians as to the possible origin of the most common and uni- versal botanic terms, one seems forced to conclude that they ac- cepted this doctrine of the sudden and inspirational derivation of them; and that then, as if unwilling to say so, they evaded the subject by going about the completely different and really quite irrelevant task of cataloguing the trees, shrubs, and herbs mentioned in the Bible, giving them the appellations due them according to the nomenclature of Linnaeus' Species Plantarum. This was all a mere matter of giving the Linnaean Latin names of certain plants in place of their more ancient Hebrew names. It was not approaching by so much as one step the origin of botany, but rather, as I have said, evading the search. Assuming that the simplest and most universally employed botanic terms entered into human speech not all at once by sudden and supernatural illumination of one particular mind, but one after another as a part of the natural and gradual evolution of language, it will be conceded that they had been formed and in use during long ages of human existence that preceded the invention of writing. And the chief botanical interest attaching to very early writings will be, not in that they furnish a few score Hebrew or Greek names of plants which the well skilled botanist of a recent period may trans- late into the terms of modern nomenclature; it will be in this, first of all, that they incidentally record names of some plant organs. Such words as fruit, seed, branch, leaf, and root occur, and these seem to reveal it that plants in numbers have been looked into and studied organologically, and with such success that these names of different parts of trees and herbs are already an indispensable and a firmly settled part of every language. Moreover, the terms tree and herb, grass and grain tell as plainly another story, that of a pre- historic distributing of plants in groups according to resemblances. These two kinds, or at least two phases, of botany are in the writings of Moses and of Homer, and perhaps more valuable because there only incidentally, that is, without botanical thought or purpose in the minds of the writers themselves. They only happen to give us, as through a window accidentally left open, a view in which we see individual plants consisting of named parts or organs, and also assemblages of individual plants, some spoken of as grass, some as herbs, some as thorns, others as thistles, some as bushes, others as trees. Though it be no more than a passing glimpse that one has gained, it is enough to excite curiosity, and to suggest a number of 1 Genesis vol. ii, pp. 19, 20. 24 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 queries legitimately botanical as to just what, in so primitive a time, may have been the full meaning and acceptation of this or that morphologic or taxonomic term as thus early in general use. Such questionings may not necessarily be idle or useless. There being no room for doubt that as far back as the time of Homer, and even of Moses, there was at least here and there a person somewhat specially skilled in the knowledge of plants, how would such a one have applied, for example, the term root? How many things, in his mind, would have been included under that name? What, in a word, might have been his definition of a root? Possibly we shall never know. Neither is it wholly impossible that we may some day ascertain it, at least approximately; for not so very many cen- turies after Homer specialists in plant knowledge began to write books upon the subject. Some of those books are still extant, and in print ; though they have been made too little use of thus far by our historians, some of whom appear to have been disposed to divide the honors of elementary plant organography between Adam and Linnaeus; which was an easy way of evading an important though most difficult part of botanical history. In the writings, I say, of the earliest of professedly botanical authors there would be reasonable expectation of finding a clue to that primitive conception of the root which was theirs who introduced the word into speech; for always the first work of him who is ready to reform and rebuild a science is that of showing wherein the prevailing opinions are at fault. To him nothing is more necessary than this. Our appeal in this instance must be made to Theophrastus of Eresus, whose writings on the philosophy of plant life and form are the oldest that are extant. As a controversialist this philosopher is of the mildest type; more apt to suggest, urbanely, that an old opinion may be wrong than bluntly to pronounce it false. His whole treatment of the subject of the roots of plants reads as if he had gone to work stealthily to undermine an old and every- where received opinion that roots are simply the underground parts of plants. He names two or three familiar species which, as he reminds his readers, produce roots that are aerial, or at least not subterranean. Then he cites, and very well describes, certain subterranean parts — bulbs and corms, we call them now — which he thinks hardly ought to be considered roots. That Theophrastus openly discredits the doctrine that a root is a root because of its being subterraneously located is proof enough that it was the doctrine commonly received in his time. We are also perfectly warranted in believing that the exceptions he takes LANDMARKS OF BOTANICAL HISTORY GREENE 25 to it are his own and new; because no writer in ancient times was more careful than he to attribute to their proper authors any new or remarkable opinions which met with his own approval. But, that the primeval understanding of the root was that which I have sup- posed is again attested by its universal prevalence in our own time among people who have not been initiated into, or influenced by, the botany taught in our schools. Such peoples, dwelling in all parts of the world, if engaged in farming or gardening hold to a certain classification of farm products, and are wont to speak of grain crops, root crops, etc., using the last named expression with- out ever a suspicion that a potato is a kind of branch, and an onion a kind of bud. Beyond doubt a very great majority of the in- habitants of the earth to-day, if questioned upon the matter, would answer promptly, and fearless of contradiction, that whatever part of a plant grows beneath the soil is its root ; and if any remotely domiciled rustic between Nova Scotia and Patagonia should re- mark that a white potato is a tuber and that onions are not roots but bulbs, we should know without parley that his abandonment of the principles of primeval plant organography had been brought to pass under the influence of modern book or school. The survival of these primitive notions about the subterranean organs is more interesting than the origin of those notions. The tardiness of their displacement by a more rational organology is to my mind one of the curiosities of botanical history. That most complicated and difficult of organs, the flower, began to be well understood as early as the dawn of the eighteenth century; but at a time when, by the aid of better microscopes, the important function of stamens had been brought to light, and the doctrine of the flower thereby revolutionized and nearly perfected, it still remained that the rhizomes of iris, the bulbs of lilies and tulips, and the corms of crocuses were called roots by all the botanists; this also some two thousand years after Theophrastus of Eresus had suggested that it might not be very good organology. And as for our historians, I have not found with one of them any intimation of who it was who at last solved for us the hard problem of an acceptable definition of a stem; the definition which at once com- pelled the recognition of subterranean stems as being stems, not roots. In my view this has always appeared to be one of the most signal triumphs of organographic research. Using the term under- standingly and comprehensively, organography is more than half of botany. It is the whole foundation and framework of the science, and a good deal more than that. The progress of botany 26 SMITHSONIAN MISCELLANEOUS COLLECTIONS V DL. 54 all along is largely identifiable with the advancement that has been made in the knowledge of plant organs; yet it is just this which one is able to learn least about from the historians. This statement must be qualified by the admission that, as regards that sudden leap forward which anthology made early in the eighteenth century, Sprengel is quite explicit ; though he gives little indeed of its earlier history. It is also acknowledged that the story of the rise of microscopic organology, and its progress down to the middle of the nineteenth century was given by Sachs, and with such fulness as to make it occupy more than half his entire volume of the History of Botany. Still these are but separate and disconnected chapters in the real history of organology. If I here indicate this incompleteness of the history of botany as hitherto presented, it is not because I dare hope in these land- mark chapters to make good the deficiency, though earnest and laborious effort is made to show how I think it may be done. That prehistorically and primevally there existed not only an organology of plants but also a classification of the familiar kinds has already been suggested; and the proposition may here receive clearer statement. Moreover, certain somewhat stilted and pedan- tic views rather widely prevalent respecting systematic botany as of recent origin, no less than the interests of a truer philosophy of botanical history, seem to call for a vindication of this thesis. Owing to the profusion of plant individuals on the face of the earth everywhere, the bewildering diversity of their forms, and the usefulness of them to man, it was never possible for men, at whatever stage of mental development, to intercom- municate concerning plants without having group names for them. Words that should have application to particular as* semblages or kinds of plants were among the earlier necessities of language; and to speak of plants under group names is nothing less than to speak of them as already classified. The classification has necessarily preceded the invention, and the adoption into language, of the collective name. By way of illustration I select out of a hundred or two of plant names which in our English speech are as old as the language itself, the word "clover." It tells its own story. It was applied to certain plants which were seen to have this common characteristic, that each leaf was made up of — cloven into — three separate equal and in every way consimilar leaves. I say leaves in order to avoid being anachronistic ; because leaflet is a term of really very modern invention; one unknown in English, and without its equivalent in any other language, at least of Europe, LANDMARKS OF BOTANICAL HISTORY GREENE 2J until the middle of the seventeenth century. Now clover was from the first the name of an assemblage of individuals; if of in- dividual plants of several somewhat different kinds all exhibiting the common leaf character then it was what it now long has been — a generic name. It ought to seem superfluous to say that clover is just as much a generic name as Trifolium, and that white clover, red clover, and alsike clover are as perfectly binary specific names as Trifolium re pens, T. pratense, and T. hybridum; but, as I have intimated already, the curious notion is here and there prevalent that a genus is not a genus, nor a species a species, until it obtain a Latin name. I have thought desirable to indicate thus plainly the incontestable fact that to the most primitive and untaught of herds- men and cultivators, in their close dependence upon many mem- bers of the plant world, generic names and specific are as much a necessity, and as certainly in every-day use, as they are with us their school-taught posterity who call ourselves botanists. The true philosophy of botanical history seems to call for special in- sistence on this fact; as also that the viewing of a number of related genera, and the speaking of them under a family name, is likewise of a very remote antiquity. The English collective plant name "pulse" is as old as the language itself, as covering under a mono- syllable all the sorts of peas, beans, vetches, and lentils. It is nothing less than a family name, invented as a means of briefly designating the whole natural group of those cultivated plants of various genera which, in recent botany, are called Papilionaceas. Ancient Latin writers, to whom many genera of umbelliferous plants were known familiarly, saw plainly their interrelationship and called the whole assemblage of them the Ferulaceae, naming it after the well-known genus Ferula which, as a genus, is represented by several species in the Mediterranean flora. And all this the Latins had only borrowed from a still more ancient Greek botany; for the Greeks had known as well the genus Ferula under the name Narthex, and were used to speak of the whole line of related genera as the Narthecodes. From these two or three lucid examples of the naturalness of plant classifying taken from the records of antiquity, let us pro- ceed to make some enquiry into like usages as they obtain among the most untaught in our own time. It is improbable that there may not be found in every country of the Old World peasant peo- ples who, entirely uninfluenced by books or schools, have never- theless each some rudimentary system of botany; some terms expressive of their own classify ings of plants, at least such kinds of 28 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 them as they have much to do with, whether as herdsmen, as cultivators of the soil, or as woodsmen. An American student, however untravelled except in his own broad country, may have gathered even here illustrations enough of the principle now under consideration. To the colonists and early settlers of a new country no native products of the soil are more important than the trees. Timber, lumber, wood for all kinds of building and fencing purposes, for the construction of bridges, vehicles, and household furniture, not to speak of fuel, bark for tanning purposes, and in autumn mast of nuts and acorns for the fattening of swine for the slaughter — these are among the reasons why early settlers always located their first domiciles along the edges of great forests. And now, if we remind ourselves of certain conditions of the first colonists who came to these shores from western Europe three centuries ago, we shall realize that, while they found themselves in the midst of a land bountifully supplied with timber, the particular kinds were new and strange to them. Nothing was quite the same as anything that they had known in the Old World; and no kind of informa- tion would have been more welcome to these colonists than that relating to the enduring and wearing qualities of the woods of these different kinds of strange trees. Every kind was untested, and there was no one to teach them. All had to be learned by trial and experience. Yet not quite all; for, to a band of colonists of three centuries ago, coming to these shores from England, there must be credited such knowledge of English trees and timber as was usual with Englishmen of that period; a knowledge that would be of some service to them as American colonists notwithstanding that American trees were of a much greater number of species, and none quite identical with and European kinds. They had brought with them across the sea a knowledge of oak, walnut, chestnut, beech, elm, linden, and some other trees. As for the chestnut, the beech, and the linden, they found but one kind of each here, and these not very notably unlike their congeneric European species. The settlers would naturally expect to find the American trees of these sorts available for the same economic purposes as their European allies. Neither as to the aspect of the trees nor the qualities of their wood was there so much difference; but with those very important timber trees, the oak and the walnut, the case was different. In place of the one European kind of walnut, the Virginian forests presented, them with at least a half-dozen, each strikingly unlike the Old World LANDMARKS OF BOTANICAL HISTORY GREENE 2Q type, both as to characteristics of foliage and fruit, and as to color and qualities of the wood. If one type of these peculiarly American walnuts bears to-day the name of White Walnut, l it is undoubtedly because the first settlers of Virginia, taking it for a probable equi- valent of the English Walnut for lumbering purposes, found its wood to be by comparison much lighter in color, and named the tree, after the usages of lumbermen, by the color of its wood. The Black Walnut 2 in like manner obtained its name from the almost blackish hue of its wood compared with that of the tree of Europe.3 And both these names bear distinctly the marks of an early colonial origin; for no native American woodsman of however early a period would have known the wood of the European Walnut so as to have made the comparisons. From this representation of colonists as practical woodsmen— beyond all cavil an essentially faithful representation — it appears that men without the least training in school botany, exploring the woodland resources of a new continent with none other than utilitarian ends in view, find systematic botany an indispensable necessity, create for themselves a serviceable system of woodland taxonomy, make themselves the pioneers of taxonomic research in the new field; this not, however, as using the terms taxonomy and classification; not even as necessarily knowing so much as the name of the science which they are practising. Let us distinguish mental processes. Nothing more is here needful. He who is occupied with testing wood or timber as to its economic usefulness is doing the part of the industrialist. He who compares one sort of living tree with another, noting by what marks of habit, of bark, of foliage or of fruit the two may be distinguished, and who determines to call one of them by one name and the other by some name that is different, is doing exactly the work of the botanical systematist. This man may never have learned a syllable of the terminology employed in schools of botany. He may not have heard the Latin name for oak, for maple, for poplar, or any other genus of trees, or even the word genus ; but he is a botanical systematist none the less ; and since his business obliges him to be this he proves the utility of botanical system. It is not possible for the occupations of the farmer, the herdsman, or the lumberman to be carried on without botanical classification and a fixed nomenclature of both genera and species. Therefore those thus engaged have never at any time in 1 Juglans alba, Linn. 2 Juglans nigra, Linn. 3 Juglans regia, Linn. 30 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 history waited for the schools and the school-trained botanists. They have made their own botany, have established both system and nomenclature; and these, in so far as they had proceeded, the professionals when they came upon the scene adopted. The two, that of rustic, of mountaineer, of herdsman, and of woodsman, and that of the schools, are as essentially one botany, as certainly one in kind, as wild pears, wild apples, and wild grapes are respectively one in kind with their cultivated and improved offspring of the orchards and vineyards. If this be true, then the annals of botanical science have another beginning than that which our annalists have assigned it. When once it is seen that group names for plants are as old as language, and that these very names establish it that men always in all ages classified the many plants with which they had to do, there is another matter which immediately calls for careful in- vestigation, that is, the parts of the plants to which rude primeval botanists looked for the marks by which to range their plants in convenient groups. We have already seen that Adanson alone among historians perceived that attempts had been made down through all the centuries to group plants by other data than those of flower and fruit. In bringing this fact into view, and by citing a long line of early authors in attestation of it, he was fearlessly contradicting, and at the same time successfully controverting what his contemporary, Linnaeus, had said when in the warmth of his zeal for the great Cesalpino he had pronounced him first in the order of time among real systematists. l The truth about .Cesalpino was simply this, that he had been the first to attempt an orderly arrangement of the plant world by universal appeal to the fruit and seed ; and that alone would still have been the super- lative of praise, doubtless well merited. But that the Cesal- pinian system seemed incomparably superior to every one that had preceded it could never become a warrant for saying that those systems antedating it might be left out of view altogether, as never having been systems at all. I can conceive of nothing which science more inflexibly exacts of every scientific man than truth- fulness. She cannot permit an enthusiastic fancy to take the place of fact. But there have been successive generations of botanists since Linnaeus who, as if swearing by his authority as if he had been infallible, have seemed to have no idea that any plant classifying ever was attempted upon any other than that antho- carpological basis which now for some three centuries has been 1 Linnasus, Philosophia Botanica, § 54. LANDMARKS OF BOTANICAL HISTORY GREENE 3! steadily in use. As a mere prejudgment it is deeply seated in the botanical mind of to-day, that nothing can be done, or ever could have been done, in the direction of an orderly arranging of the world of plants but by appeal to characters of flower and fruit. And along with this prejudice there dwells another as deeply ingrained, namely, that the flower was the same thing to botanists of four hundred years ago, if not to those of three thousand years since, which it is to us; whereas not yet two centuries have passed since the flower began to be known. Our classifying by flower and fruit was fairly established while as yet the corolla was regarded as the principal part of the flower, and was in fact the synonym for flower, without even its name corolla. Something may be done towards undermining these prejudices by giving a few examples of primitive systematizing as undertaken while as yet the flower, as to its essentials and its functions, re- mained an undiscovered organ. For a good illustration of classifying by leaf characters alone, those of flower and fruit being quite ignored, we need go no farther back than the later years of the sixteenth century and the first quarter of the seventeenth. Let us limit ourselves to the forty years intervening between 1583 and 1623; also inspecting certain pages of two of the widely known and thoroughly approved professional botanists of the time, Rembert Dodonaeus and Caspar Bauhin. The genus Clover, in ancient Latin Trifolium, in Greek Triphyllon, already referred to in this chapter, is an ample one with the authors named. Bauhin's book contains names and descriptions of some sixty species ; and since both he and Dodonaeus are almost as strict adherents of binary nomenclature as was Linnaeus himself who came into this field of nomenclature a century later, it will be easy to show what they received into the genus Trifolium by presenting here two opposite columns of binary names. In as far as they admitted to their Clover genus genuine clovers as we now un- derstand them, the reproduction of their names need not be made. Dodonaeus (1583), and Bauhin (1623) Recent Names Trifolium bituminosum Psoralea bituminosa. Trifolium odoratum Melilotus officinalis. Trifolium corniculatum Lotus corniculatus. Trifolium cochleatum Medicago orbicularis. Trifolium palustre Menyanthes trifoliata. Trifolium acetosum Oxalis acetosella. Trifolium hepaticum Hepatica triloba. 32 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 It ought here to be noted that for the combining of Melilotus with Trifolium, Dodonaeus is reponsible but not Bauhin, who at this point saw fit to abandon the trifoliolate leaves as essentially and without exception conclusive of membership in Trifolium. He does not, however, as others had done before him, accept the melilot species as constituting a genus of their own, but places them all as members of the genus Lotus, where also some species are trifoliolate, others not so. I observe also that if only the first four of the species of the above list had gained admission to Trifolium along with the clovers proper, one might have thought it probable that some dependence, after all, had been placed upon the floral structure; for in that case the authors would have had a Trifolium composed of papilionaceous plants exclusively. But neither in the defining of the genus nor in the description of a single one of the about sixty species of Bauhin's Trifolium is any mention made of the morphology of the flower. And by the admission of gentian aceous, oxalidaceous, and ranunculaceous types into that genus it is placed beyond question that in his mind the genus was limited by nothing else but the herbaceous nature of the plants, ternate foliage, and dry fruits. I say dry fruits, because in Bauhin's book the strawberries, as typic- ally trifoliolate as the most genuine of clovers and as herbaceous, stand in closest juxtaposition to them, and it is manifest that their, juicy berry-like receptacles, with seeds all on the outside, saved Fragaria from being merged in the Trifolium of that author. And in this giving so much attention to the fruit where flowers were wholly ignored we see the influence of Cesalpino's great treatise; for Bauhin and Cesalpino were contemporaries, in a manner, the former younger by thirty years. All through such books as have here been cited one reads the resoluteness of purpose and the hard perseverance with which men labored to improve botanical system by studying and comparing texture and duration of stems, and above all else the morphology of leaves; a very crude system at its best; but system of some sort there had to be; the flower was still virtually unknown; the fruit was barely beginning to be appreciated in its usefulness to taxonomy ; therefore the vegetative organs, chiefly the leaves, were most commonly allowed to be decisive. The appeal to leaves was not, however, first thought of in either the seventeenth century or the sixteenth. Even then it had been more or less in vogue for three or four thousand years that we know of. LANDMARKS OF BOTANICAL HISTORY GREENE 33 As a good example of an antique genus of trees based on leaf characters alone, with no dependence on those of flower or fruit, one recalls the Daphne of the Greeks. The original Daphne with them was the sweet bay, Laurus nobilis Linn., the type-species of the genus Laurus as now received. Its foliage, being lance-shaped, of a somewhat leathery texture, with no marginal indentation, repre- sents a rather common leaf type, and the tree is evergreen. Now there was a period of Greek history within which there was not only some travel to foreign lands, but even some written reports about the natural products of other countries; and there is the most convincing evidence that every new tree or shrub that came to light that was both evergreen and clothed with oblong or lanceolate entire leathery leaves was at once relegated to the genus Daphne; was named as another kind of laurel. Here is a list, possibly not a complete one, of trees with Laurus foliage which ancient Greeks, on that account alone, had referred to that genus: Laurus nobilis, Nerium Oleander, Nerium odorum, Avicennia offiiinalis, Rhizophora mitcronata, Ruscus Hypophyllunt1 ; six species of so-called Daphne or laurel, belonging to five different genera, and representing as many different families, all anciently accepted as of one genus, because the foliage in all was much the same, and for no other reason whatsoever. And this again reminds us that in eastern North America, where there is no laurel, we have a number of kinds of native shrubs that have always been called by that name, just as if they had been members of the genus Laurus to which they are in no wise related. If we ask ourselves how this false naming came to pass, the answer is, that at the time of the early colonization of this new continent the old Greek idea was still dominant, that whatever bush or tree had a laurel foliage was a good enough laurel. The colonists brought that idea hither, and naturally enough applied the name to our Kalmias and Rhododen- drons one and all. This classifying by foliage was never received as anything like a general principle everywhere to be applied. So far from that, the rude primitive groupings were accomplished here and there under the sole guidance of the fruit ; though in the main only as to none but its most superficial characteristics. Among fruit-bearing trees the apple tree was perhaps the oldest and most familiar type, unless the pear be excepted; and as new kinds of fruit trees in the course of history became introduced into Europe from other lands, every kind, the fruit of which was of considerable size and of something 1 Bretzl, Botanische Forschungen des Ahtanderzuges, p. 405. 34 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 like the sphericity of the apple, was called a kind of apple tree, a member of the genus Mains, as it was called in Latin speech and writing. Here is a partial list of the kinds of Mains, or apple tree, that find record and description with several early authors; excluding, however, the true apples, which were of many varieties all with binary names. Malus Armeniaca Armeniaca vulgaris. Malus Persica Amygdalus Persica. Malus arantia Citrus aurantium. Malus limonia Citrus limonium. Malus medica Citrus medica. Malus cotonea \ Malus cydonia Cydonia vulgaris. Malus aurea } Malus Punica ) Punica granatum Malus granata j Malus Indica Zizyphus jujuba. In outline, the history of the development of such a genus Malus as the above is this. In primeval southern Europe they had the common apple tree, Mains commnnis, and, from the beginning of the historic period at least, they had it in many culti- vated varieties. The fruit was malum with the Latins, the tree mains. Then, as other kinds of trees were introduced from the East having spherical or ovoid fruits not too small for apples, their fruits were also designated as kinds of apples, and the trees as species of malus. To us who, with also several generations of our botanical ancestry, have become accustomed to a greatly improved classifica- tion, such a piece of systematizing as the above list of apple-tree species exemplifies cannot but seem absurd; but the presentation of something of that kind was necessary, partly in order that we might realize from what small and simple beginnings our later and better systems of carpological classifying have been evolved; also partly as demonstrating the groundlessness of the Linnaean hypo- thesis that classification by fruit characters took its rise with Cesalpino, and as late as the end of the sixteenth century. I am unwilling to dismiss the subject of early and practically pre-Cesalpinian classifying by fruit without having given one more illustration of it. For this purpose I shall again advert to the taxonomic procedures of the early Virginian colonists. I have cited the case of their having found there, in place of the English Walnut, two allies of that tree, and that they named these new LANDMARKS OF BOTANICAL HISTORY GREENE 35 kinds Black Walnut and White Walnut respectively; also that this naming of the kinds was made not in reference to any morpholo- gical characters of the trees, but to that of the colors of the wood; this having been done quite after the manner of self-taught wood- men, whereas school-taught botanists would have assigned names suggested by organographic marks. But this all relates to nothing else but the making of specific distinctions and the assigning of specific names. When we ask ourselves by what marks they were able to refer these new trees to the genus of the walnuts, we obtain but the answer that it was by those of their fruits; these in such degree resembling that of the one kind of walnut before known to them as to warrant the conclusion that the trees were of the walnut kind, as they would have expressed it, rather than of the oak or chestnut kind. But our colonists' experiences with the native American oaks, if they had been more fully recorded than they were, would have been still more interesting. As English woodsmen only one kind of oak can have been well known to them. In Virginia they can not have failed to meet at once with about a half-dozen sorts, most of them in aspect exceedingly unlike the English Oak; so much so that they can not reasonab y be supposed to have identified them with that genus of trees at all until after close inspection. One of the sorts displayed to them the foliage of the chestnut tree, another that of the laurel, still another the leaves of a willow. The chest- nut-leaved kind had not at all the bark nor the wood of chestnut trees, but of oaks, rather; therefore these first observers of the tree would hardly have needed to appeal to the fruits in order to satisfy themselves that this new tree was but an oak, merely imitating the chestnut as to its foliage. But among the other kinds, such as had neither foliage nor bark nor wood in any way answering their idea of an oak tree, they can not have determined to be oaks by any other note in each but that of its fruit. That which I have thus far hypothecated concerning early Vir- ginian colonists in relation to native Virginian oaks is demonstrable as something more than even the most rational of hypotheses. There is documentary evidence of the historic truthfulness of all, and more than all, that I have here but intimated as probable. That these men, forced by circumstance to make trial of the timber of trees new to them, did early recognize as oaks certain kinds most unlike what they had known as oaks, in all except their fruits, is attested by a colonial list of names of new American oaks which was published when the colony was but two generations old. I re- 36 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL 54 fer to Banister's Catalogue. l This contains a list of binary names of Virginian oaks, such as Quercus alba, Q. rubra, Q. Hispanica, Q. castanece folia, Q. salicijolia. Now while a casual reader of the catalogue cited would, without a second thought about the matter, attribute those five names to Banister, it is extremely unlikely that any one of them was invented by him. It is next to certain that the whole five are his mere translations into Latin of the oak names that he found in use among the colonists. Perhaps the plainest proof of this is, in that by turning those five binary names back into English you get precisely the names by which five com- mon oaks are known to dwellers in that same region now, two hundred and twenty-seven years after Banister's having written his list. It is really evidence that is incontestable. To dispute it would be to affirm that the names were made by Banister himself, in Latin, then turned into English for the use of the woodsmen settlers; that these had been waiting sixty years or more for the professional botanist to come and tell them by what names to call their several kinds of oak; each part of which proposition, like the whole of it, is absurd. Under pressure of necessity, and from the outset, they must have begun to learn the different qualities of the wood or timber of those strange new kinds of oak. One or two of them were found comparable with the familiar oak of the mother country as being hard, durable, subserving the purposes of the builder, the wheelwright, and the cabinet-maker; another, not subject to decay when set into the ground, useful for posts; still another durable only when used for bars, rails, and like purposes; and there may have been a fourth and fifth kind excellent for winter fuel, but nearly worthless otherwise. No man will pretend to believe that colonial woodmen and handicraftsmen, learning by degrees the different qualities and uses of our various American oaks, did not immediately assign a particular name to each particular kind. The important industries of house-building, boat-building, cabinet- making, the constructing of vehicles, the building of fences, and the providing of the winter's fuel, all demanded quite imperatively that there be a well ordered and generally accepted system of woodmen's nomenclature of oaks as well as of othe; genera of timber trees. So it came to pass that all important trees everywhere, in America quite as elsewhere, had their established names before the arrival of the writers of floras and silvas; and there is many a kind of tree the Latin name of which bears the i Banister, Cat. Plant. Virg., transmitted from Virginia to John Ray in 1680; published by Ray, in Hist., vol. ii, in 1688. LANDMARKS OF BOTANICAL HISTORY — GREENE 3 7 * mark of its having been originally the woodmen's vernacular name for it. Hitherto this fact of the universal existence of a crude primitive system of plant classification — one that antedates all botanical writing, a system that is in vogue to-day all over the world in out- of-the-way places, in complete isolation from the influence of colleges and universities — appears to have remained unnoticed by botanical writers. At least, I have met with no allusion to the fact. I therefore doubt that it has entered into the minds of botanical thinkers in recent times that such untutored yet effective and useful plant taxonomy exists, and must have existed primevally. There will be readers enough to whom this thought will be new and somewhat startling. The fond conceit has long prevailed, that there was never anything in the world that could be called science until some three centuries ago, or four, at the farthest. Among several ideas about the botany of the past — ideas very widely, almost uni- versally, entertained, though without the least warrant from history — I shall here mention but the following : that plant genera did not obtain fair recognition until Tournefort, nor species as distinguished from varieties until Linnaeus, nor families before Adanson. Now if, according to the present thesis, the beginning of the receiving and naming of common plants in groups is ancient beyond all possibility of discovery, then no author can be credited with, or any date be assigned for, the beginning of the recognition and naming of either genera or species. What great men like those just named accomplished for the improvement of system in botany was, the better delimitation of several anciently accepted genera, and the laying down of certain rules and principles by which they thought all plants, known and unknown, might be arranged in groups more nearly according to their affinities. Assuming that the rules and principles were philosophic, all this was immensely to the advantage of classification ; but when for the twofold purpose of emphasizing the principles and making the new system easy to learn, they caused each genus name to be printed in large type, in the middle of the page, occupying a line by itself, then close under that the formal statement of its characters as a genus, and after that and only less conspicuously the species names, each occupying a separate paragraph, they were by this rigid formalism inaugurating, though they knew it not, an era of didacticism which now after two centuries has degenerated into an almost gross pedantry which rules systematic botany at present well-nigh •universally. To illustrate the supremacy of this pedantry let me SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 suppose that some accomplishe'd botanist of Italy or France or Ger- many, having a new genus to propose, ignores all the usual post- Tournefortian formalities in his naming and defining of it. This will mean only that, declining to follow established typo- graphical usages, he does not place the new generic name in large letters in a conspicuous place above all that he has to say of it, but begins his paragraph with a statement that the type is new, thence proceeding without a break to name the marks by which the genus is distinguishable from all its allies, then directly adding, in the same type and without the formality of an initial capital, even in the middle of a line, if it so happen, the name by which he proposes that the genus shall be known; all this followed, still without break- ing the paragraph, by whatever else he may have to say about the plant or plants of this new genus. Between such simple uncapi- talized compact taxonomic paragraph as I have supposed, and the familiar stereotyped form of naming and defining a genus, there is at first glance the appearance of great dissimilarity. As to the meaning of the two, and the information that is conveyed, there is no shade of difference between them. The plant type, supposing it to be the same, is as fully described and as certainly named in the more simple paragraph as in the one that is ostentatious. All that the botanical scholar can learn from the one he may learn just as perfectly and just as promptly from the other. Really the differences between the two are hardly more than typographical; yet notwithstanding this, it is probable that forty-nine out of every fifty botanists of to-day, if not even a much larger proporton of them, would in part fail utterly to perceive that the simple unosten- tatious paragraph which I have supposed, with generic name in small type set in the midst, had been intended as the publication of a new genus; and it is as probable that those of the forty-nine who did perceive the author's intention would deliberately ignore the paragraph, under the plea that the name and characters of a genus printed in a style so very unconventional must not be ad- mitted to answer the requirements of publication. The genus must be treated as unpublished. This, be it noted, will be the same as to order that a new scientific fact be, in as far as possible, suppressed for the reason that certain familiar usages as to type and para- graphing were not followed in the publication of that fact. It will be regarding form of expression as superior to the facts expressed ; will be allowing individual whim or fancy to ignore important matter; will make for the establishment of shallow pedantry in place of solid information and the use of plain good sense. I have LANDMARKS OF BOTANICAL HISTORY GREENE 39 stated this case hypothetically ; but there are provinces where the situation is to-day actual. But the greater number of my hypothetic forty-nine, as I have said, will even fail to discover that a plant group has been named and defined on any page where the modern typographical conven- tionalities are not in evidence. I think that among such as are quite proficient in systematic botany there are many whose im- pression of the printed pages of Ruellius, of Dorsten, and of several other classics of sixteenth-century botany would be that they give no account of families, genera, or species; and this only because great authors had not then learned to make a separate paragraph for every group, and to print the names of genera and of species in type different from and more conspicuous than that used for the descriptive passages. There is no question of the superior con- venience of our modern style of printing taxonomic matter; still, for the mistaking of mere incidentals for essentials by people professedly scientific, it is not easy to frame excuse. But the psy- chologic fact is well established that men do in this wise err, and that there are multitudes of biologic taxonomists whom familiar usage has completely deceived into thinking that no name is generic unless printed in large letters; multitudes of botanists who will have been startled by the proposition incontestable that clover, parsley, hazel, and birch, all as here printed, are names as perfectly generic as TRIFOLIUM, APIUM, CORYLUS, and BETULA. Moreover, there have been learned historians of botany in post- Tournefortian times whose minds appear to have been under the same delusion, and who thereby missed one of the fundamentals of the philosophy of botanical history. It is impossible that men, even the most primeval and unlettered, manage their affairs with various denizens of the plant world without classifying them. Names of plants, generic and specific, and also other names more comprehensive, are a part of the ver- nacular of every tribe of the uncivilized, as well as of that of every rural province within the bounds of civilization to-day. The very names attest the fact of classification; for no name is that of an individual plant. It is that of a group of plants, always; a group specific, generic, or more comprehensive than either. It may occur to some that the named groups recognized by the untaught do not in their delimitation correspond to those that obtain with the professional plant taxonomist; as if that, if it were true, would in the least alter the situation or affect the argument. It will be difficult to understand how the vernacular genera of the 40 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 ruralists can possibly correspond to the Latin-named genera of the scientific botanists when the latter themselves are seldom at agreement among themselves as to the exact limits of any considerable genus, or of any polymorphous species. When we ourselves may have learned to agree as to where one of our Latin- named groups is to end and the next is to begin, may we with some propriety criticise the same kind of doing as accomplished by the unindoctrinated. And now let me demonstrate it, that in the history of classification the unlettered vulgus now and again has been first to arrive at the satisfactory delimitation of a natural group, the learned doctors having arrived at this same judgment later by one or more genera- tions, and so as to seem to have adopted it from the untutored laity. This point may perhaps be most easily made plain by return- ing to the contemplation of North American colonial botany and the colonial dendrologists. It was shown above, that all the several American trees of the walnut alliance with which they became ac- quainted, although all, in certain particulars, different enough from that one Old World walnut which they had known, they called walnuts ; precisely the same as if they had denominated them species of JUGLANS, which would have been the case assuredly, had they but known and used the Latin terminology in place of the English. We, of three centuries later, dispose of these American trees dif- ferently, referring nearly all of them to another genus; but what is remarkably to the credit of that colonial and primitive taxonomy is, that so exalted an authority as Linnaeus found no fault with it, but simply adopted it. With him all the different kinds figure as good enough species of JUGLANS, and bear with him even the. same specific names which the colonists had assigned, but of course Latinized. When, in a preceding paragraph, I gave early American colonists the credit of having recognized and named as oaks a considerable list of native acorn-bearing trees; even as having determined them to be oaks by their acorns alone, I felt that there might be demurrers to the opinion that these had not learned this mark of the genus Quercus from the^schools in some more or less indirect way. I may well, therefore, here place it beyond dispute that in this case also the unlettered men of field and forest did arrive at the proper delimitation of a genus of trees quite in advance of the professional taxonomists, and these last virtually adopted the genus, as we now have it, from the ruralists. In the first decade of the seventeenth century, when the Virginian colonists were beginning to learn the LANDMARKS OF BOTANICAL HISTORY — GREENE 4! industrial uses, and at the same time the characteristic superficial — as we should now say morphological — marks, of many new trees, there was yet no book of botany extant, in as far as I can learn, in which it was taught that any and every tree that has an acorn for a fruit is hereby known to be a Quercus. Neither Pliny nor Tourne- fort, nor any author of the fifteen centuries that intervene between those two, has fewer than three distinct genera of acorn-bearing trees. With each and all of them a tree bearing acorns, in order that it may be of the genus Quercus, must be deciduous, and its foliage sinuately lobed. In other words, none but deciduous white oaks are properly called oaks by these old authorities. Trees bearing acorns, but evergreen as to foliage, the leaf margins prickly, are of a separate genus, Ilex; while those oaks of southern Europe with peculiar foliage, along with a thick spongy bark, — cork oaks, we call them, — are of a third genus, Suber. At the time, therefore, when Banister was turning into Latin those English binary names which colonists had given to Virginian trees bearing acorns, there was not yet a book of botany extant in which it was taught that its yielding acorns was a sufficient warrant for naming a tree an oak. It was only the country people, the woodmen, who held that view as to the extent of the genus Oak. The learned John Ray, the same who received from Banister the manuscript catalogue of Virginian plants and caused it to be published, himself never swerved from the doctrine then time-honored and classic, that we have here three genera, Quercus, Ilex, and Suber, yet expressly states that " the common people so extend the name Quercus as to include under it all kinds of trees that bear acorns. " 1 In as far as I have been able to trace the history of oak classifying on the part of pro- fessional botanists, Linnaeus appears to have been the very first to repudiate what had been the opinion of all his predecessors, and to adopt as more true to nature the more comprehensive genus Quercus which the vulgus had invented. And so, if we of the pres- ent, following Linnaeus as to the limits of Quercus, are in the right, then let us concede freely the fact, from which there is no escape, that during long centuries the unlettered vulgus was taxonomically correct, while all the learned botanists were wrong. By means of the popular nomenclature of common ornamental plants, one is able to see how those uninstructed in botany readily classify things according to floral structure. Everywhere lovers of flowers have a group of plants which they call by the collective name of lily. This happens to be many times more comprehensive L_ '.Ray, Historia Plantarum, vol/ii, 1385 (1683). 42 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 than the lily genus of the modern professionals; though not so widely different from that of the books of botany of some centuries ago. It embraces Lilium, Fritillaria (Checkered Lily), Hemero- callis (Day Lily), Amaryllis (Belladonna Lily), Vallota (Scarlet L ly) , and many another genus of liliaceous and amaryllidaceous plants, besides Convallaria and the members of several iridaceous genera. All of these have showy flowers of the same morphological type as that of the true lily. And to this floral type even the white funnel-form spathes of certain araceous plants have been associated, as the name Calla Lily plainly betrays; though it is not to be doubted that the entire, narrow, veinless foliage of all these plants has helped in the making of this popular generic synthesis. And then, on the part of the botanists, the analyzing, assorting, and systematically arranging of these diverse elements of the primitive genus lily — the genus as even now, I say, accepted by a great multitude of mere flower lovers — has occupied a great number of taxonomic specialists during later centuries. The care- fully gathered records of the gradual evolution of our present taxonomy of the lily-flowered plants would fill a thick volume; would most perfectly establish the fact that those botanically untaught sometimes classify by the flowers; would illustrate how different generations of professed taxonomists have made their various appeals to different organs, some to the flowers chiefly, others giving much weight to considerations of roots, bulbs, and corms, while others were more influenced by considerations of the- pericarp and seed. And such a book, in its completeness, would form an instructive epitome of the whole history of botany. It would be as easy to produce instances of a primitive classifying by characters of the root; or, at least, of those subterranean parts of plants which, until within a very recent period, were universally confused as roots. But it may be unnecessary to multiply proofs of the existence of an almost more than fragmentary, and really rather extensive system of what one may paradoxically denominate pre-botanical botany. Enough may have been said already for the accentuating of the opinion that there are beginnings of our science which the historians should not have overlooked. It has been out of those crude beginnings that learning and philosophy have developed what we now call the real systematic botany. They are even the prothallium from which at length there has arisen the frond of whatever strength and symmetry and grace there may be in the now accepted taxonomy of plants. This condition of things being once seen and admitted, we shall LANDMARKS OF BOTANICAL HISTORY GREENE 43 for the first begin to be able to understand, to appreciate, and to interpret the earliest botanical authors; not those only of ancient Greece and Italy, but of the fathers of botany in England, in France, in Germany, and Switzerland; a worthy company whose true position seems to me never to have been half understood, and whose works have therefore more or less completely baffled the attempts of profound scholars and eminent botanists who in the capacity of historians, have sought to elucidate the texts of these forefathers and to show what they severally accomplished. Botany did not begin with the first books of botany, nor with the men who indited them; though every historian of the science whom I have read has assumed that it did. The most remote and primitive of botanical writers, of whatever country or language, found a more or less extensive vocabulary of elementary botany in the colloquial speech of all. The chief organs of plants — stem, trunk, branch, leaf, flower, fruit, pod, seed, root, tendril, thorn, and a multitude of others — had been discriminated and named; the organs even known by all who had acquaintance with plants and trees, and the names were everywhere in use. Even the functions of several of the or- gans had been correctly ascertained before ever a line of botany had been written; most probably even before letters had been invented. The improvement of wild things by cultivation, the propagating of the newly acquired sorts by cuttings, by division of perennial roots, and, in the case of trees, by grafting, are likewise arts that seem to antedate history; as do also the designating of different varieties or species that are evidently nearly akin, by twofold names, one generic, the other specific or varietal. All these conditions being recognized, a new and peculiar difficulty will confront the critical student of a protobotanical author. It will in exceptional cases seem doubtful as to whether a given fact or generalization is the fruit of that author's own investigations, and therefore new with him, or whether it be something already long understood and accepted, which he is but placing upon written record. It is, however, a kind of difficulty that gives zest to the study of classic texts; and many such doubts may give place to certainty, or something near it, after persevering examination, and comparison with other passages that are not of doubtful import. I am unwilling to conclude this introduction without repeating it, that the essence and substance of botany proper are organ- ography and the logical deductions that we draw from organography. They may not be said to be the whole of the science ; yet duly and comprehensively considered they will be found to come near it. 44 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 The line of the development of organography — organography as necessarily including terminology — is that along which a truly coherent and philosophic history of botany must needs be written. The condition is one that will entail the expenditure of incalculable time and unremitting toil ; but the cost of time and energy must not be counted if anything beyond disconnected and fragmentary paragraphs of history are to be the outcome. CHAPTER I THE RHIZOTOMI IT is characteristic of all very early phytography that the root, that least obvious and most hardly accessible of plant organs, is as carefully described as are the stems, the leaves, and the fruits. This fact that the first of all describers of plants should have taken the root into account, and that so uniformly and so particularly, must seem strange enough to every thoughtful botanist of later centuries; it is in such marked contrast to the descriptive usages with which we of the present are better acquainted. In the voluminous and carefully technical phytographic works of the eighteenth century and the nineteenth, one may chance upon successive pages filled with descriptions of scores of species, about the roots of which not a word is said. Nothing like this occurs in any book or chapter of Theophrastus,Dioscorides,or any other classic botanical writer. In the case of every species of herbaceous plant, and of many that are woody, they do not conclude a description without telling us what the subterranean parts are like, whether fibrous or fleshy or tuberous or bulbous, usually informing us as to the colors of these organs, as well as the properties of them when they are known to have any. And so carefully did the fathers who wrought a revival of botany in the sixteenth century follow those classic models that, in their illustrated folios, never a plant is figured the root of which is not as faithfu ly delineated as the foliage or the flower. Even in the letterpress accompanying the plates of Brunfels, Fuchs, Tragus, and others, the root is as well described as the foliage, and much better than the flower. All this for the simple reason that the great masters of remote antiquity had set them the example. But how did it come to pass that the ancient Greek botanists were so almost singularly familiar with the underground parts of plants, and that they so accentuated the importance of them to phytography? One would not have ex- pected this, and it seems almost anomalous. No one who ever went forth to make philosophic conquest of the vegetable kingdom 45 46 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 was confronted at the outset by the roots of plants. These parts are recondite. He who for any purpose would inspect a root must undergo the labor and inconvenience of digging about the plant, wresting that root from its hiding-place, and then cleansing it, so that its characteristics may become visible and tangible. When all is done, there is a great sameness about roots. They do not promise much aid to him who would find marks by which to dis- tinguish between like and unlike. Stems present a much greater diversity, and either leaves or flowers or fruits a hundred times more differences by which to distinguish plants, than do these underground parts. It being granted that the function of the root as a vital organ was thoroughly understood, as it appears to have been from the earliest historic period, still, as regards early de- scriptive botany, there would have been less reason to be surprised if the early fathers had commonly ignored it ; or at best had made as little account of it in their descriptions of species as most of the modern systematists have done. And there must be a philosophy of this very ancient and once universal appreciation of the root as a subject of phytographic notice equally with stem and leaf. The cause must, if possible, be ascertained. If the ancestors, even somewhat remote, of the first botanical philosophers had been savages such as, in dearth of animal food, had found the subterranean parts of many a wild plant available in its stead, then would there have been some show of reason for that singular prestige which roots had obtained so almost prime- vally. In the transition from savagery to civilization such root- food plants would have come into cultivation, where they would have held their place and been well known to enlightened posterity. But at the time when writing about plants began, at least with the Greeks and Latins, roots and bulbs constituted but an inconsiderable part of their table fare. The bulk of their farm and garden pro- ducts were the cereals, orchard fruits, pot-herbs, and salads. The ancestry of the philosophers for centuries, possib'y for millenniums, had been highly civilized, perhaps to the degree of having lost the traditions of nomadic life and the feeding upon wild products of the plains and woodlands. In this civilization, however, the art of medicine held an im- portant place ; and in this circumstance we have a clew to that pre- dilection for describing so faithfully the roots of everything which is so almost peculiar to the phytography of the ancients and their sixteenth-century imitators. Throughout the whole period of Greek antiquity there was a LANDMARKS OF BOTANICAL HISTORY GREENE 47 class of men who followed as a regular business the gathering, pre- paring, and selling of roots and herbs that were of repute in medi- cine. It was of course naturally inferred and easily ascertained that whatever properties perennial herbs possess are concentrated in their subterranean parts during the season of the plants' rest in autumn and winter; so that what were called the roots of plants formed the bulk of the materia medica. All this the very name of rhizotomi, root-gatherers, sufficiently declares. The botanists of antiquity, that is to say, they who inves- tigated the plant world as philosophers rather than as econo- mists, inform us that the rhizotomi were mostly unlettered men, usually more superstitious than scientific, observing an ex- tensive ritual in the digging as well as in the after prepara- tion of their simples; evidently mixing medicine and magic after a manner almost universal in the early history of the healing art; as often attributing to their preparations magic virtues as medicinal. Concerning some of the ceremonies of the rhizotomi we have information.1 There were various prayers and incantations to be said or sung. Some kinds of roots were to be dug in the day- time, some others by night only; the powerful plant hellebore, only after the observance of various precautions. The point of a sharp sword must be drawn three times around certain roots to make them more efficacious. The gatherer of some sorts must be careful to face the east while digging. In the case of others he must stand on the windward side of the plant. Some require to be collected by one newly anointed with oil. As preparatory to the culling of other kinds, the rhizotomos must eat garlic and drink wine. As modern and as learned an author as Kurt Sprengel relegates all those observances without discrimination to the category of foolish superstitions2; this, as it seems to me, incon- siderately. There are plants enough the exhalations of which are so deleterious that persons of delicate organism may be un- comfortably affected by the mere passing close to them on the leeward side, of a breezy day. Any discreet American botanist not immune against Toxicodendron vulgare, if tempted to gather specimens of it, would use among other precautions that of holding himself to the windward of the plant if there happened to be a breath of air stirring. His act would be adjudged sane and rea- sonable. Another such precaution might be that of using gloves while handling any parts of the plant ; whereas an old-time oriental, 1 Theophrastus, Hist., Book ix, ch. 9. 2 Sprengel, Hist. Rei Herb., vol. i, p. 63. 48 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 with whom the anointing of the body with scented oil was a com- mon practice, might successfully use oil instead of gloves while gathering particularly acrid herbs and roots. Also when one is informed that the ancient drug gatherer never proceeded to dig certain roots but with breath laden with an odor as intolerable as that engendered by garlic and alcoholic drink, there is still no reason to charge that to superstition; any more than the surveyor or handicraftsman, whose work for the day is in the midst of a steaming and unwholesome marsh or fen, makes free use of to- bacco smoke as, by the physician's counsel, tending in some degree toward immunity from malarial influence. With us who believe so much in the efficacy of malodorous disinfectants as bringing immunity from infectious and malarial disease it should seem natural to attribute similar precautions to Greeks of 4000 years ago, especially when assured, as we may assure ourselves, that even at that remote period one of the rhizotomi propounded the theory, now in our day revived, that myriads of germs, minute, invisible, permeate every atmosphere. Such partial apology for some of the so-called ritual observances of the rhizotomi is no digression. The historians have usually re- ferred to them as in large part a body of superstitious fakers. Such, to a degree, many of them may have become in the long course of centuries during which their profession flourished. Super- stitious observance is often enough the end of that which in the beginning was a reasonable and sensible measure of precaution; and it is not a legitimate office of history to exaggerate the differ- ences subsisting between an earlier and a later age or race. The agejDf superstition even as regards medicine and pharmacy, though passing it may be, is not yet quite past. If the scholarly Sprengel cites the ceremonies of the rhizotomi with impatience, it is because he is influenced — as many another passage in his work makes it evident — by an almost morbid abhorrence of everything that to him has the appearance of a superstition. If anything appeared to be an empty ceremony, he could not tolerate the thought of it long enough to examine into the possibility of its having had an origin that was scientific and utilitarian. If the rhizotomi were mostly illiterate men and quacks, still there were exceptions. Here and there among them there seems to have been a man of letters ; and a few investigated plants more or less scientifically, and wrote books. The names of several such have been handed down through history, together with some of the more original and remarkable of their sayings. THRASYAS MANTIN- LANDMARKS OF BOTANICAL HISTORY GREENE 49 ENSIS is mentioned by Theophrastus as one of the worthiest among them, because as if ignoring the common beliefs about magical effects he gave himself to the investigation of the properties of plants. He seems to have been the original proponent of the doctrine that the good or bad effects of a medicine may depend upon the temperament of the individual patient; a proposition which has met with some acceptance, at least outside the pro- fession, if one may judge by its having been long since crystallized into a proverb, that what is medicine to one, may be poison to another. The idea is revolutionary, though without yet having brought about much of a revolution. To this same Thrasyas is ascribed the compounding of that vegetable poison, so frequently in use with the ancients, which never failed to bring a speedy and absolutely painless death.1 Theophrastus devotes two chapters to an account of the pharmacological researches of this Thrasyas, and those o his eminently successful disciple Alexius, and of those of a third of the same school of intelligent and really scientific rhizo- tomi, Eudemus of Chios. One and another of these men, living at periods so remote as barely to fall short of being prehistoric, tested in their own persons the adaptability of the human system to the harmless use of drastic and poisonous vegetable substances. Be- ginning with small doses and increasing them gradually, it was ascertained that one might after a time consume without bad results such a quantity of hellebore, for example, as under ordinary conditions might have proven fatal. Using at first earthen pots and pans in the probing of questions about possible or probable antidotes to certain poisons, they would proceed, under the light gained by such experiments, to the using of their own stomachs as the crucibles.2 And the reports of these instructive and daring experiments, together with the names of the men who made them, were either written and subscribed to at the time or else handed down by tradition to the time of Theophrastus who gave them per- manent record. Among the earlier rhizotomi there was a famous one named CLEIDEMUS, who wrote upon the subject of electrical storms so as to have been quoted by Aristotle in his Meteorology.3 He also in- vestigated diseases of plants, especially of the fig-tree, olive-tree, and vine. Cleidemus is therefore the earliest of vegetable pathologists. And what may be more interestingly significant is this, that Theo- 1 Theophrastus, Hist. Plant., Book ix, ch. 17. 2 Ibid., ch.'iS. 3 Aristotle, Meteor., Book i, ch. 2. 50 SMITHSONIAN* MISCELLANEOUS COLLECTIONS VOL. 54 phrastus credits him with having maintained that there is the closest analogy between the organs of plants and those of animals. Infor- mation like this can not fail to awaken regret that the writings of Cleidemus have not survived; it would now be so Very interesting to know whether this genius o a forgotten time went so far beyond those of later periods as to have apprehended the existence of breathing organs and those of sex in plants. HIPPON was among the rhizotomi who philosophized about plants in general, and wrote books. His waitings are quoted by both Aristotle1 and Theophrastus,2 and he appears to have been the earliest among students of plant life and form to venture the opinion that all cultivated trees, shrubs, and herbs have been derived from wild ones, and are susceptible of reversion to their pristine condition. It is the earliest hint — and a very early one, apparently unknown to the annalists of evolution — of what cultivation may accomplish in the way of transformation. But the doctrine must have had the sound of a heresy verging toward atheism in the ears of a populace that had never questioned the proposition that every cultivated plant and tree had been coeval with the human race, and had been so created at the first. But it is not that small, better-educated, more reflective, and philosophizing contingent of the rhizotomi, or the possible influence of these few upon early botanical theory, that we are just now chiefly concerned with. It is rather that in this whole body of those who, for so many pre-Theophrastan centuries, followed the root-gatherers' calling, we have the men who securely established that precedent, from which the earliest philosophic students of and writers about plants did not break away, of taking full cognizance of those among plant organs which nature had most deeply con- cealed, as if they were perhaps the last and the least to be considered. It was the example of the rhizotomists, in their books of plant description extant in the times of Aristotle and Theophrastus, that impelled Theophrastus and others after him to give the form, texture, color, odor, flavor, as well as the active properties, when these were known, of the roots or underground parts of almost every plant. And when, as already noted, it is seen that from Dioscorides and Pliny down through the middle ages, and out to near the end of the seventeenth century, authors in general de- scribed and figured the roots of every weed and grass and bush and tree, it will be conceded to have been the lot of the half-illiterate » Aristotle, De Anim., Book i, ch. 2. 2 Theophrastus, Hist Plant., Book i, ch. 6. LANDMARKS OF BOTANICAL HISTORY — GREENE 51 rhizotomi to make their peculiar impress upon the character of descriptive botany, an impress that should last for well nigh two thousand years 1 The occupation of the root gatherers is by no means peculiar to Greek antiquity. In every part of the world it may be as old as, or older than, .he beginnings o: civilization. Nor is it probable that in Europe there was any interruption or cessation of the occupa- tion during the two thousand years intervening between the time of Homer and Hesiod and that of the Renaissance. The botanical writers of the sixteen h century, particularly those of middle Europe, refer to the practices, and even to the opinions, of such as ransack the woods to gather roots and herbs, sell them to the druggists and to the peasantry whom they serve in the capacity of physicians, and from whom the educated and philosophic students of plants themselves sometimes gain valuable information. Nor would it be safe to say that the rhizotomi are even now everywhere obsolete. Their traces are very plainly legible in the popular nomenclature of North American plants. Every common name into which root enters as a component is one that had its origin with the "herb doctor," or "root doctor," as he was called; per- haps not a few of the names were borrowed, along with some infor- mation about the plant's virtues, from the aborigines.2 1 It was Valerius Cordus, the greatest if not the only botanical genius of the first half of the sixteenth century, who first gave expression to the opinion that, from the morphologic and phytographic point of view, the importance of the root had always been overestimated. He set the example for a reform of descriptive botany in this particular; but, as usual with men of genius, he was a century in advance of the ideas of the multitude. 2 The following are illustrative examples: Alum-root, Blood-root, Bowman's-root, Culver's-root, Cancer-root, Canker-root, Black Snakeroot, Button Snakeroot, Seneca Snakeroot, Indian-root, Musquash-root, Colic- root, Pappoose-root, Pepper-root, Pink-root, Red-root, Yellow-root, Sheep- root. It were easy to double the number of such names of American plants, not one of which was assigned either by a learned physician or a professional botanist. CHAPTER II THEOPHRASTUS OF/1ERESUS. B. C. 370-286 (or 262). LINN^US, in the practice of his favorite art of systematizing classified not only plants but the writers about them. The writers he distinguishes primarily as Botanists, and Plant Lovers; recogniz- ing as Botanists only such as treat of plants from some philosophic or scientific point of view. Choosing his illustrations from the an- nals of remote antiquity, he names among the earliest of the Greeks who wrote of plants Hippocrates 1 ; but because he wrote of plants only in the interests of medicine Linnaeus styles him Father of Medicine ; a title that had been conceded to that worthy ages before Linnaeus, and will be accorded him until the end of time, no doubt. Similarly Aristotle, who is also known to have written upon plants, but whose volumes on that subject have been lost, is down in the Linnasan list of ancient celebrities as Prince of Philosophers. To Theophrastus, however, he accords the title Father of Botany. From this opinion, far from having been newly promulgated in Linnaeus' time, there has been no dissenting voice. On the con- trary, Albert Haller, one of the most learned men in Europe in his day, and a botanist o : such renown that Linnaeus held him in reverence, and also in some fear, denominates Theophrastus " the first o: real botanists in point of time. " 2 Curtius Sprengel in the nineteenth century, having rehearsed the names of a long line of ancient authors who had written more or less concerning plants, says: " But the most illustrious of them all, and the true father of botany, was Theophrastus Eresius. " 3 If the author of the latest of nineteenth-century volumes of botanical history, Julius von Sachs, makes but passing mention of Theophrastus, along with the names of Galen, Dioscorides, and Pliny — as if he had not been otherwise a botanist than they — he may be more or less excusable upon the 1 Linnaeus, Philosophia Botanica, § 9. 2 " Primus verorum botanicorum." Haller, Bibliotheca Botanica, vol. i, p. 31. 3 " Celeberrimus autem omnium, verus rei herbariae parens, THEOPHRASTUS fuit Eresius." Sprengel, Historia Rei Herbariae, vol. i, p. 66. 52 LANDMARKS OF BOTANICAL HISTORY GREENE 53 ground that he was not engaged upon a general history of botany, but only dealing with the short period intervening between the years 1530 and 1860 of our era. However, that Sachs had no acquaintance with Theophrastus, or even of Dioscorides, is proven by this, that he credits his sixteenth-century German compatriots with having gone straight to nature and described plants originally, whereas the truth is that nearly all the plant descriptions occurring in Brunfels and Fuchs, are almost word for word translations of the ancient paragraphs of Theophrastus, Dioscorides, and others; sometimes with a few words of their own added, as often with none. And as regards that exact and intimate knowledge of plants which comes of the careful study of them alive and growing, it is safe to say that all which Sachs' sixteenth-century German fathers knew combined, would have amounted to but a fractional part of Theophrastus' knowledge, and that much of their own observing had been suggested to them in their reading of his books. An abstract of Theophrastus' work should enable the unbiased and impartial to judge for themselves whether scientific botany had its beginning with those good German herbalists of the six- teenth century, or with an immortal Athenian or two who had lived, studied plants long and carefully, lectured to thousands of students, and written down the substance of their botanical lec- tures seventeen centuries earlier than they. Life. Mitylene, a large and rich island in the ^gean Sea close by the coast of Asia Minor, was famous millenniums ago as having given birth to many an illustrious personage. Arion and Terpan- der, ancient masters of the art of music, Alcaeus and Sappho, un- rivalled among lyric poets, as learned critics gather from the fragments of their masterpieces that remain — these names but head the list of celebrities that had been born on that island in the earlier half of the thousand years next preceding the beginning of the Christian era. How very famous this island was for the ex- cellent quality of its products, material, artistic, and intellectual, is shown in the fact that Greeks and Romans of a somewhat later period, wishing to bestow the highest praise on anything, whether it were a piece of music, a verse of poetry, or a cask of wine, were accustomed to pronounce it Lesbian — that is, fit to have come from Lesbos, the name by which the modern Mitylene was known anciently. Such are a few of the available hints of the environ- ment in which the protobotanist was born in the year B.C. 370. His birthplace was Eresos, the most important town of the island, whence he has been styled Eresius — the Eresian, perhaps to dis- 54 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 tinguish him from others of his time who bore the not uncommon name Theophrastus. His father's name, Melanthus, and that of his boyhood's teacher at Eresos, one Leucippus, have found a place in history only as associated with that of this child and youth whom they called Tyrtamus. We shall be warranted in inferring that the child was o: unusual gifts and marked by nature for the intellectual life; also that Melanthus, the fuller, was in comfortable circumstances financially, for the educational advantages that were given the boy were then somewhat rare and costly. How well the child had improved his opportunities is attested by this, that while as yet but a- youth, he was away beyond the farther shore of the ^Egean Sea, at Athens, and there numbered among the disciples of Plato. All historians of the period credit him with having been under that philosopher's instruction before coming to Aristotle; and as Tyrtamus was only twenty-two years old when Plato died, it is plain that the enrolment among Plato's pupils must have been made when the subject of our sketch was but a youth — possibly a precocious, eager, ambitious boy only. The histories all read as if Aristotle's marked friendship and ef- ficient patronage had had very much to do with establishing the fame and directing the luminous career of Theophrastus. There must be a large measure of truthfulness in this representation, though it is more than possible that it is somewhat exaggeiated in Aristotle's favor ; and history should take cognizance of the universal and even necessary fact, that in great friendships the influences are mutual, just as when, in the heavens, two planets move to their conjunction each influences irresistibly the orbit of the other, draws it some- what aside from what should have been its path. The story, as always rather too briefly told, leaves an impression, not intended to be made, of great disparity between the two both as to years and some other controlling influences ; seeming to represent Tyrtamus as the brilliant young favorite, and Aristotle the elderly admiring teacher and foster- fatheily patron. That the youth, as if irre- sistibly obedient to an old and revered master's mandate, should have renounced the name Tyrtamus that he brought with him from the paternal home in Eresos, so that henceforward he should be Theophrastus, is something to create almost a convic- tion that the one was old and masterful, the other young and submissive, and not to be thought of as an influence upon the thought and action of the elder. Such impressions are wrong, and must vanish by a comparison of certain well authenticated dates, which show that Aristotle was Theophrastus' senior by only LANDMARKS OF BOTANICAL HISTORY — GREENE 55 fifteen years; also that the two were fellow students under Plato. Aristotle from the age of seventeen to thirty-seven had been Plato's pupil. Tyrtamus, it may reasonably be assumed, entered Plato's discipleship at seventeen if not earlier. If so, he may have been Aristotle's student companion there for from five to seven years be- fore the day when Aristotle left Plato and opened a Lyceum of his own. Shortly after this Plato died; and then, unless he had done so even earlier, Theophrastus became Aristotle's student. And as for this new name, it is not necessary to suppose that it was bestowed merely as the flattering compliment paid a highly promis- ing young student by an old preceptor. The two were in truth much upon an equality. They were companions and much at- tached friends, with no signal disparity between them as to years; so that the change of name may well be thought to have been brought about by mutual agreement. I can not but wonder at the boldness with which Meyer pro- nounces this change of name from Tyrtamus to Theophrastus to be a fable. ! No one else has questioned the authenticity of this part of the biography ; and he has not been able to adduce so much as one valid reason for his pronouncement against its truthfulness. One of his supposed reasons is, that Aristotle was no flatterer. To have rendered this an argument, Meyer should first have disputed the sincerity of Aristotle's friendship for Theophrastus; for between genuine and devoted friends flattery is impossible. But he says the name Theophrastus was not uncommon among Greeks of the period, which is equivalent to saying that, if the philosopher had been going to give his disciple a new name he would have selected some uncommon name, or else that the Eresian had always been Theophrastus and never Tyrtamus. That "such a changing of names was unknown" is quite as inane as the rest of this historian's argument upon the subject. Not one in ten thousand of the ancient Greeks has been known to us by any name at all. Even of that comparatively very small number whose names we have heard, who shall say that none besides Theophrastus ever underwent a change of name because the event if it happened was not recorded? There is not the least reason for thinking that with Greeks, in passing from one age or condition of life to another, the taking of a new name was uncommon. There were distinguished examples of it among some of their neighbors, the Hebrews, for example. Meyer concedes that this "fable" about Theophrastus was uni- versally received as a fact by all the ancients, and we add that it 1 E. H. F. Meyer, Geschichte der Botanik, i, p. 147. 56 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 is as perfectly authenticated as any other fact or incident in Theo- phrastus' life. He who can make fiction of this part of it may upon similar grounds invalidate, piece by piece, the whole biography. No reason having been given for doubting about this incident, every one to whom the appellation is not meaningless will see that Tyrta- mus was a grotesque name, if not a ridiculous one, to be borne by a scholar and orator of commanding presence and predestined great renown. The young man himself, as well as his master and friend, must have realized this; and it is hardly to be doubted that the displacement and rejection of the unsuitable name was the first object which the change had in view; and that what the new name should be was but a secondary consideration — a matter of less importance. Indeed, the biographer Laertius relates that at first the Eresian began to be called Euphrastus, and then later Theo- phrastus. Posterity should be grateful that the change was made; and also grateful for that devoted attachment between the two philosophers by which it came to pass that the elder of them, dying in middle age, had his own work taken up, and carried forward with success during almost another half-century.1 It was such a friendship as led Aristotle to give to Theophrastus his owrn library, said to have been the richest one then in existence, and to have included the manuscripts of his own wrorks, a treasure which by means of Theophrastus' jealous care was almost singularly pre- served, and handed down to posterity well-nigh complete. Also the botanic garden which Aristotle had established at Athens was made a gift to Theophrastus; by whom also it was newly equipped, variously improved and adapted to greater usefulness; this, too, on a scale so extensive, that a wealthy friend of Theophrastus and benefactor of science is named in history as having borne the expense of those improvements.2 The fact of the existence of this Athenian botanic garden will explain how Theophrastus, oc- cupied as he was with the management of, and also engaged in teaching in, a school of two thousand students, with no time or opportunity for travel, gained so intimate a knowledge of the life histories of many plants as he surprises us with in certain chapters of his books. He had studied in that garden at morning, noon, and 1 Aristotle died at the age of sixty-three years. Theophrastus was then forty-eight; and, according to his own statement in his preface to that book entitled Characteres, he had finished it in his ninety-ninth year. St. Jerome says that Theophrastus died at the age of 107. 2 The name of this first wealthy patron of botanical science was Demetrius Phalereus, according to Laertius, vol. i, p. 350. LANDMARKS OF BOTANICAL HISTORY GREENE 57 evening for perhaps sixty years or more when, almost a centenarian, he wrote such clauses as the following in his will. They should help us to a realization of the scientific zeal and activity of a jor- gotten time. " I bequeath to my friends, who are specially named in this my Will,1 and to those that will spend their time with them in learning and philosophy, my garden, walk, and houses adjoining; upon condition however that none of them shall claim any particu- lar property therein, or alienate them from their proper use; but that they shall be enjoyed in common by them all. as a sacred place where they may familiarly visit one another and discourse together like good friends."2 And further: " I desire to be buried in any part of the garden that they shall think most suitable; charg- ing them not to be at any superfluous expense either upon my funeral or upon my tomb. Which being done, my will is that Pomphylus who lives in the house take care of everything, as he did before."3 That Pomphylus was an overseer, directing the labors of bonds- men gardeners owned by Theophrastus, comes out incidentally in another clause. " As for my boys, it is my will that Molo, Cymo, and Parmeno be forthwith set at liberty. As for Manes and Callias, I will not have them given their freedom until they shall have la- bored four years longer in the garden, so that there be no fault found with their labor and diligence; but after that, let them have their freedom. " Besides these five, two others are mentioned. " I give Cano to Demotimus, and Donax to Neleus."4 By means of this testamentary document, the transcript of which has been fortunately preserved, one is able to realize something of the extent, and even of the perpetuation during perhaps three generations, of this pristine garden for biologic research. And this realization will be exceedingly helpful toward a comprehension of the magnitude of Theophrastus' work along these lines. The philosopher was never, like many of his class and in his time, a traveller. He did not devote any more than a fraction of his time to botany. His writings on this subject amount to perhaps not more than a twentieth part of all that he did in the line of written authorship. And there are chapters in the Historia Plantarum that 1 Hipparchus, Neleus, Strato, Gallic, Demotimus, Callisthenes, and Cresarchus are their names, according to Laertius, vol. i, 361. 1 Laertius, vol. i, 358. 3 Ibid., 359. « Laertius, vol. i, 360. Note also the botanical names of the two young slaves Cymo and Donax. 58 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL, 54 are so crowded with facts about seeds, seeds in process of germina- tion, young seedling plants and older ones, observations upon this plant and that shrub as they appear in spring, summer, autumn, and winter, that, all being considered, we should have wondered greatly how this most untravelled and sedentary of the great philosophers had gained all this minuteness of knowledge about the little things of plant life had we not been informed concerning this great garden in the midst of which he dwelt, taking' his daily recreation along its paths, and among its seed beds, and within the bounds of which, obedient to his last request, they buried him. Theophrastus was a voluminous author, having written upon a great diversity of topics. The biographer Laertius gives the titles of 227 treatises. Not many of these have reached us; but among those preserved are the Historia Plantarum, in nine books, with the fragment of a tenth, and the De Causis Plantarum, origin- ally in eight books according to ancient records, of which the last two have long been lost. The following paragraphs are the result of a prolonged and laborious study of the principal work, the His- toria, the edition quoted being that of Stapelius, published at Amsterdam in 1644. As we have already seen,1 there existed in the old Greek literature that was before Theophrastus, many a trace of properly botanical observation and reflection, so that he is not in such wise the father of botanical science as that no one before him had recorded a philo ophic thought or suggestion about the plant world separately considered. Yet he is, in most cases which he cites, the sole per- petuator o the name and fame of such as Menestor, Hippon, and Leophanes whose passages he quotes and in quoting has saved from oblivion. There is, then, no reason to suppose that in his philosophizings about plant life he had been helped by any pre- decessors beyond that for which he has given them full credit. It has been observed by historians and critics that a few passages in Theophrastus are also in Aristotle, unaltered, and uncredited to their real author. This hardly merits notice. It is undoubted that the enlistment of Theophrastus' great talents in the service of botany was secured by Aristotle; and it is as certain that the alliance between these two celebrities of antiquity was that of the most devoted friendship; that at Aristotle's demise all his manu- scripts, published and unpublished, complete and fragmentary, were gladly bestowed on Theophrastus. They became his property. 1 See pp. -(8-50 preceding. LANDMARKS OF BOTANICAL HISTORY — GREENE 59 He was free to dispose of them, to publish any parts of them, ac- cording to his own judgment. Modern science and erudition have no example to show us of like community of even intellectual property between two illustrious friends. Moreover, from the fact of Theophrastus' having lived and studied and written during half a century after Aristotle's demise, we are warranted in thinking of him as of one who had acquired a great store of knowledge about plants beyond all that to which Aristotle in his briefer day had attained. As having been the author of the oldest distinctively botanical treatise that is extant, the place of Theophrastus is unique, and invites to special and careful consideration. He writes from the midst of an advanced civilization ; a state of society in which there is much farming, extensive cultivation of the vine and olive, fruit growing, market gardening, and cultivating of medicinal, aro- matic, and ornamentally flowering herbs, shrubs, and trees; a time when many improved varieties of all sorts of things have been derived through cultivation, and when it is already perfectly well known that such improved varieties can not be depended on to come true to seed, but may be preserved, and the stock of each increased by division of roots, by cuttings, and by grafting. It is also a time when the very masterpieces of literature — some of them even in Theophrastus' time ancient and classic — abound in facts and fancies and myths and fables about flowers and fruits, shrubs and trees. Of course all obvious and familiar parts of plants — their organs — have their names. These are a part of the common vocabulary of things. Also group names for growths that are alike are in as universal requisition. If a genus evidently con- sists of several different kinds, be they what the botanist of the present would denominate species, or be they notable varieties only, each such kind is designated in speech or writing by a cog- nomen; so that a binary nomenclature, precisely that which all farmers, gardeners, and foresters find needful and have always created and employed, is perfectly established. Such, in brief outline, is what Greek civilization had attained to in the way of experimental knowledge of plants, independently of all philosophy, and without help from the philosophers. And if Theophrastus had been less than a botanical philosopher, and if as a mere annalist he had but recorded the untaught industrial and experimental botany of his period, together with that very considerable vocabulary of botanical terms which then formed a part of the Greek language, he would still have done us an ines- 60 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 timable service; though masters of the science in the seventeenth, eighteenth, and nineteenth centuries of our era would not have styled him Father of Botany. In our study of this maker of the first Landmark in the History of Botany the main object must be that of discovering in what ways, under what limitations, and yet how well, he accomplished the placing of knowledge of plant life and form upon the list of the sciences. Method. That a treatise be recognizable as scientific it must be methodical. It is even a necessary characteristic of it. There must be a principle, or a set of principles according to which the facts or propositions find an orderly arrangement. This does not, however, imply that the method or system be of some par- ticular kind, as, for example, that in botany one should be required to arrange the matter of one's treatise according to what are con- ceived to be the natural affinities between plant and plant. The author who writes botany from the industrial point of view, if he so elect, may discuss his plants in the order of their relationship in families, genera, and species; or, ignoring taxonomy of that sort, he may arrange them according to the nature of their serviceability in household economy and what are called the useful arts; may discuss in successive chapters food plants, drug plants, textile plants, vegetable dye-stuffs; trees, as supplying timber, fuel, oils, gums, sugars, resins, nuts, etc. That botanical matter so arranged may be scientific can not successfully be controverted. Theophrastus of Eresus might have adopted such a method as this last. He was abundantly capable of discussing the plant world from the economic and utilitarian standpoint ; indeed, had he so arranged the substance of his work he would but have been following established precedent. Every treatise on plants which was extant in his day was of the nature of agricultural, horticultural, or medical botany. There was not yet any other method of arrangement for botanical writing but the economical. Furthermore, his own chapters everywhere abound in references to the qualities of plants, and their uses in the economy of human life ; though such references are commonly supplementary to the statement of other and differ- ent considerations. The very title of his work, History of Plants —in more idiomatic English, The Story of the Plants — seems to look toward an investigation of this realm of nature for its own sake, the vegetable kingdom thought of philosophically rather than industrially. No work was yet in existence, unless one by Aris- LANDMARKS OF BOTANICAL HISTORY GREENE 6l totle which has been lost, in which plant organ was discussed in relation to plant organ, and the kinds of plants in relation to other kinds. The prevailing attitude of mind respecting the plant world was not such as would tend to the encouragement of other than utilitarian views of it. That these objects were brought into exist- ence only with reference to man, and for his use and benefit, was even a part of the religious belief. And so deeply seated and generally prevailing was this sentiment that it is said the students of Aristotle and of Theophrastus became objects of ridicule with some of the literaries, poets, satirists of the time, because of their going about the country picking up and curiously peering into the least little things of nature, such as were of no possible use. And one may not attribute to antiquity alone these prejudices against philosophic nature study ; for they rule the mind of untold millions even now. Antiquity, in this phase of it, is with us still, in the ideas of the uncivilized races, and also in rural districts of the lands of the enlightened. Not many a botanical traveller and explorer along the frontiers and in the remoter country sides has failed to be accosted with friendly queries respecting plants of which he has been seen to be making specimens : What use has this plant? What is that kind good for? And what betrays in these good-naturedly inquisitive rustics their complete subjection to the pre-Theophrastan utilitarian botany is, that when the man of science answers frankly that he knows no use whatever for the plants in question, he is not believed, but is silently credited with wishing, for his own pecuniary advantage, to keep their use a secret. The adherents of this archaic philosophy of the vegetable kingdom are, I say, doubtless numbered by thousands on all the continents; people who have not heard of any other; and we have no proof that another had been any more than merely suggested before Theophrastus. In the Second Chapter of the philosopher's First Book there is presented the following list of the external and obvious organs of a highly organized plant, i.e., a tree: root, stem, branch, bud, leaf, flower, fruit. 1 I recall that upon first reading these initial chapters of Theophrastan botany I was quite startled to find here this com- plete and faultless statement of the external organs of a tree or shrub; to be confronted with it even here, and be made to realize that it is so very, very old; that our own masters and tutors of a few years ago did not invent it, neither their own immediate > Hist., Book i, ch. 2. 62 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 botanical ancestry, but that all so-called modern botany has this fundamental of plant-morphology from old Theophrastus. and all unawares. But the surprise passes. The sentence is so simple, so natural, so logical, the connection between term and term so perfect, that one doubts that it could have been done otherwise; and may be disposed to say to himself that any botanist of whatever epoch might have gone out on a morning walk, looked at a number of different kinds of growths, come in and written down that method- ical proposition offhand. It is extremely improbable that it was so done. It is next to certain that it cost its author a great deal of careful observation and prolonged study and reflection. The sentence is studiedly methodical, and no less a dictum of science than a work of art. It is easy to forget that, as in art, the produc- tion from which all evidence of the artist's anxious care and hard work has been eliminated is the masterpiece, so in science and philosophy the axiom or the aphorism which when finished reads as easily, smoothly, and convincingly as if every one always must have seen its transparent truthfulness, and as if almost any novice in that same science might have written it down in just those words — that this is the little sentence which may have cost its author the expenditure of time and mental energy with which he might have written a whole volume upon some topic that was not difficult. If the origin of the simplest elements of universal botany is to be shown, this Theophrastan list of plant organs will have to be looked into rather particularly; will need to be studied with great care and caution. Those six or seven important terms, as our philosopher links them together, constitute the most classic piece of elementary botany in existence. The sentence has also much to reveal about the author's botanical method in general. First of all, the terms of the sentence, root, stem, leaf, bud, etc., have not been created or invented by Theophrastus. As the names of those things they are part of the common vocabulary; botanical terms, assuredly, yet in their framing and use doubtless far antedating all written botany. That our first philosopher of plant life, he who first brought the terms together and placed them in line, altered the meaning of certain of them by giving them a more comprehensive or else a more restricted application, is easily possible; though that does not here concern us. We have but to note that this fine equipment of most fundamental botanic terms, the first botanist — as we must denominate him despite the sug- gestion of the paradoxical — found ready made. They and other LANDMARKS OF BOTANICAL HISTORY GREENE 63 such terms had been the legacy to human speech made by a primeval race of nature-ponderers, almost infinitely remote and prehistoric even in Theophrastus' time. Observe now, that while root, stem, bud, leaves, flowers, etc., are familiar and obvious parts of a tree, they are far enough from being a complete list of such obvious parts. Viewed at close range the bark is very conspicuous; more so than either the buds or flowers in the majority of arboreal and arborescent growths; and since he has here left it out, one is obliged to think that this point was well inquired into by him; that the omission was deliberate, and the result of sound reasoning. We shall find proof by and by that he investigated the inner structure of trees; and there, among the anatomical parts of the tree as they disclose themselves in the cross-section of its trunk or stem, we shall find him cataloguing the bark. To separate organography into the two divisions, morphological and anatomical, is, then, also classic. It is another part of universally approved botanical method which originated with and was established by Theophrastus. With that Theophrastan list of organs under consideration, modern botany at the very outset divides it into two parts, la- beling one division of them the vegetative organs, the other the reproductive. The Greek has incidentally given us to know that he, too, pondered very seriously indeed the question of a natural division of his series, and that he effected one. It is as far as possible from corresponding to our modern classification of the same organs, and must needs have been so ; because the only repro- ductive organs of plants known to Theophrastus were seeds and buds. Of the sexual organism of the flower he had no information. He was without a microscope. His dividing line between the two classes of organs is drawn, not as with us toward the upper end of the series, but near the middle of it. Root, stem, branch, bud, form the first division; and the perfect naturalness of it may be realized by observing that precisely those organs, and no more, are what one enumerates as constituting deciduous woody plants in their winter condition. No leaf, no flower, no fruit is there; yet the organism as it stands betrays no imperfection. From its deepest rootlets to _its remotest twigs and scaly buds it is alive, in health, perfectly normal in every particular. What is more, every such tree and shrub on the face of the earth passes half the period of its life in just that condition, no difference whether that life period be fifteen years or fifteen hundred. It is a classifying of the external organs of a plant as permanent and 64 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 transient; a very remarkable division of the series, as true to nature as any classification of organs that ever has been proposed anywhere by any man, and yet, as I suppose, entirely peculiar to Theophrastus' method. How thoroughly natural and scientific this proposition is, may be further shown; as also how studiously the learned Greek nature student reached his conclusion about it. It is not the deciduous tree only whose different organs fall into the two classes of the permanent and the transient. He has dis- covered that the evergreen trees, like the rest, acquire one set of new leaves each year, and as unvaryingly lose an old set ! ; so that their perpetual verdure is due to this only, that each set of leaves remains on the tree during two or more seasons. It is clear to his mind that if leaves, flowers, and fruits are to be catalogued as plant organs at all, the division of the whole series into constant organs and inconstant must be maintained. But he is even perplexed with a question of whether those inconstant and scarcely more than occasional parts are to be listed as plant organs at all2; a position which most twentieth-century readers will think very singular and strange. But must there not also have been with him a time of doubt as to the placement of certain other very com- mon and external parts of plants? Such things as prickles, spines, thorns, tendrils, excrescences of several kinds which imitate fruits but are not — it was by no accidental oversight that these were omitted from his catalogue of plant organs. Since in the phyto- graphic and taxonomic parts of his writing he evinces his perfect familiarity with them, it becomes certain that he surveyed with his wonted carefulness the ground of their possible right to enumera- tion among these other organs, and that he deliberately ruled them out. The ground of his doubt concerning leaf, flower, and fruit as admissible into the line he states fully. Being himself first a zoologist, then a botanist, and always interested in making com- parisons between these two kingdoms of nature, he is aware that the foetus of a gravid animal is no part or organ of that animal. The fruit of plants, being analogous to the animal foetus, should be denied any place in the list of plant organs. To make this part of the Theophrastan argument quite clear to the reader, it will be needful to anticipate our study of his anthology in so far as to say that the conception of ovary and ovules as being parts of the flower is one that never entered into the mind of Theophrastus. With him those first small rudiments, as they appear still encircled by 1 Hist., Book i, ch. 15. 2 Hist., Book i, ch. i. LANDMARKS OF BOTANICAL HISTORY GREENE 05 or concealed within their colored floral leaves, are the fruit. From this incipient stage, in which, as I say, we call them parts of the flower, the Greek held them to be the fruit, and so forward to their fuller development and final maturity, always the fruit. Whether, by the way, his doctrine of the fruit or ours is the more natural, the more logical, and the less forced and arbitrary, he may determine who may divest his mind of its every prejudgment about the case. In the light of this explanation it will be easy to see that, if the fruit be denied by Theophrastus its place in the list of plant organs, the flower, that is what we call corolla, is equally disqualified, partly on account of its intimate connection with the fruit, and partly on the score of its exceeding transiency in all cases. Fur- thermore, because in the thought of the Greek the flower itself was but a circle of leaves, different from the ordinary foliage only as to form and coloring, if the floral leaves must fall short of mention in the list of important organs, the green leaves must remain with them. So the catalogue would begin and end thus: root, stem, branch, bud. Indeed, his first presentation of it is in this ab- breviated form. Now against his own argument for the exclusion of such parts from the list, he presents such reflections as the following. It is only when trees stand vested in their full foliage, flowers, and fruits, that they seem to have reached their fullness of beauty and perfection. That which makes for the perfection of an organism should apparently be accounted a part of that or- ganism. And as for permanency, there are exceptional cases among animals in which certain parts are transitory. Fowls periodically shed their feathers, and stags their horns; and his last observation here is that animals and plants are in many ways so very different in their constitution that arguments from analogy must not be pressed too far. And so, after much observation and astute rea- soning upon the subject, he convinces himself that leaf, flower, and fruit are entitled to places in the list of plant organs, where nevertheless they by their nature form themselves into a separate division. One can not but admire this piece of Theophrastan method, wrought out originally and laboriously by himself, and so unique; in its deepest meaning fairly amounting to a division of the organs as vegetative and reproductive, and drawing the line between bud and leaf — mistakenly, of course — instead of between leaf and flower. There is another mark of deep study in the making of this list. It lies there, rather well concealed from our first glance, in that elegant sequence according to which the names of the organs are 66 SMITHSOXIAX MISCELLANEOUS COLLECTIONS VOL. 54 placed: root, stem, leaf, flower, fruit. Its mere orderliness pleases one, even captivates the mind to that degree that one readily believes that it is of both natural and logical necessity, and that any single modification of that arrangement would make the whole unmethodical and altogether bad. To begin at one pole of the plant axis and proceed thence without a break to the opposite pole is artistic, and therefore satisfies our esthetic fancies. It may also be that such procession of names of plant organs is called for by scientific principle; and since our protobotanist was keenly in quest of principles and a little indifferent to matters of phraseology, we must inquire into his scientific reason for writing the root first on the list of plant organs, rather than the stem. We have already seen that primevally the root received more attention morphologically than any other organ of the series l ; that early descriptive botany is rather anomalous in this particular, and that all this came to pass through the influence of root-gatherers and their patrons the physicians and the pharmacists. Such a merely economic and commercial consideration as that which influenced men of the time in their descriptions of roots can not be supposed to have the least effect upon the mind of Theophrastus at this particular juncture, where he is engaged upon a study that is in nature purely scientific, biologic. No botanist has lived in any age of the world more capable of distinguishing between the economic and the biologic in nature study. Now in those parts of his work which are descriptive, written for the purpose of en- abling the reader to identify the plant, his sequence of the organs is different. It is now stem, leaf, flower, fruit, root; another not unnoteworthy item of Theophrastan method ; one sequence for the treatment of organs phytographically, and another sequence for the discussion of them biologically. The former is well suited to its purpose; for, to the great majority of observers, nothing is seen of any plant or tree but its stem, foliage, flower, and fruit; and any reader would be discouraged if not repelled by a description beginning with a full account of the root, about which part he neither knows nor particularly cares to know anything. As to the other and biological sequence, it is evident that the philosopher arrived at it only after careful and prolonged investigation. " In all plants the growth of the root precedes that of the superior parts." The allusion is to young plants, whether growing from seeds or from cuttings; which latter means of propagation was '[Page 45 preceding. 2 Hist., Book i, ch. 1 1. LANDMARKS OF BOTANICAL HISTORY — GREENE 67 only less extensively resorted to by the ancient Greeks than it is by ourselves; and they knew as well as we that when a cutting set into the ground has remained for weeks and maybe months with- out having been increased by so much as one leaf, that only means that it is slow in forming its roots, and that until these are somewhat grown, other growth will not begin. It is improbable that this kind of fact was not of common knowledge with gardeners and orchardmen ages before Theophrastus ; so that all he had to do was to verify it by experiment. But when he states that even within the seed it is the radicle which first begins to swell and grow, and that this is invariably the first part of the growing seed to appear outside the shell,1 we feel assured that these are fruits of observa- tion on the part of no gardener, but of a biologist. In the year 1672 of our era Nehemiah Grew, aided by a microscope (!), had repeated those investigations of the seed as germinating, and published what was but a confirmation of the view that Theo- phrastus had presented some nineteen hundred years before, namely, that biologically considered the root is first among plant organs, then the stem, and after them, leaf, flower, and fruit. One must now leave the Theophrastan method in merely ele- mentary organography, and survey briefly the outlines of his dealing with plant as compared with plant. The philosopher has several different viewpoints from each of which he perceives the vegetable kingdom as a whole to be divisible into two parts. The first of these divisions is according to texture and duration of stem and root ; a chapter in botany which he wrote for all time ; the distinction between woody plants and herbaceous. Trees and shrubs, alike as to their woodiness, are distinguished by him precisely as in the most recent botany, not neglecting the word of caution that no hard and fast line separates the two; that many, like the filbert and the pomegranate, are naturally shrubs, the stems growing in clumps, and are seen in the form and dimensions of trees only when under the cultivator's care and art. Even the pear tree, olive, and fig when left to themselves become many-stemmed and shrub-like. He also apprizes the reader that certain pot-herbs of the gardens have always the one-stemmed and arboreal mode of growth, even approaching trees in their dimen- sions, and all within the time of a few months; but that these have not the duration of trees or even of shrubs, and therefore prove that they are neither. He mentions certain mallow and cabbage > Hist., Book viii, ch. 2. 68 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 kinds as of this category.1 He denominates them Sf which his Latin translators have rendered olerarbores, and would appear in English as tree-potherbs. All herbaceous plants he classifies as perennial, biennial, and annual; also carefully stating that the annual and biennial are hardly distinguishable, inasmuch as both die, root and branch, within the space of a year, and as soon as they have once perfected seeds. While this important example of botanical method is in hand, it will be pertinent to take note of those two mental processes, analysis and synthesis, of which every piece of method is the outcome; this for the purpose of clearing our own mental vision for an inquiry into the question of how much of this classifying according to texture and duration was found by Theophrastus ready-made and in common use, and to what extent, if at all, he revised, augmented, and improved it. Problems of this kind are most difficult; even impossible of exact solution by the mere botanist. The erudition of the specialist in philology and the history of language is here called for, without the aid of which the early history of botany never can be written. Happily, however, great linguistic learning is not requisite to a few reasonable infer- ences respecting Theophrastus' part in this classic piece of method. The distinguishing between woody growths and herbaceous is doubtless older than history. It is also evident that with remote enlightened antiquity tree and shrub were distinguished. The words representing these ideas are very ancient; but the half- shrub, or suffrutescent growth as we of to-day speak of it, appears to have been set apart as a group, and assigned a distinctive name by Theophrastus himself. There are many old and classic names for plants distinctively herbaceous. There is weed, grass, herb, vegetable, even the word "plant " itself as originally used, every one implying the herbaceous as to texture and short-life period; and so much for very primitive analysis and synthesis ; but the putting of all these things together, the synthesis of them under one com- prehensive term, was, if I mistake not, a Theophrastan contribution to botanical method. Moreover, and what is of even more profound interest, it appears as if the synthesis of everything that vegetates — tree, shrub, half-shrub, and herbaceous plants, including even sea-weeds and fungi — into one vast comprehensive assemblage of living entities called plants, is also to be attributed, if I mistake not, to Theophrastus. Primeval and prehistoric observations 1 Hist., Book i, ch. 5. LANDMARKS OF BOTANICAL HISTORY GREENE 69 and reasonings, I say, doubtless established and named such lesser groups as tree, perhaps bush, certainly garden vegetable and field and garden weed, and grass and reed, rush and mushroom; but the synthesis of all as in some way alike and interrelated, and as spoken of comprehensively under one word — that would seem to have awaited the advent of a master mind like that of Aristotle. The written record of so significant a piece of method in nature study I find for the first time in Aristotle's greatest botanical dis- ciple. The fuller investigation of this topic may be deferred until we come to Theophrastus as the founder of Botanical Terminology. From another viewpoint Theophrastus beheld the world of plants as divisible into the cultivated and the wild 1 ; and he formally approves this line of separation, though almost as compelled by circumstances; for he admits that it is not natural, and that the differences are in the main such as result from cultivation. It presents, nevertheless, a forcible example of rude primitive plant classifying. Untaught peoples of all countries, and many all around us, hold to such a division, — and that even superstitiously ; firmly believing that the wild parsnip or wild carrot — differing from its parent plant only as growing spontaneously by the way- side, rather than within the garden wall under cultivation — is a poisonous thing, perilous to the life of him who would dare to eat it. Our present nomenclature of plants, the vernacular as well as the Latin, presents countless clear vestiges of the former popularity of this antique parting of all the plant world into these two divisions. Such specific adjectives as agrestis, silvestris, trivialis, arvensis, pratensis, hortensis, sativus, urbanns, and many more tell of a time past when about the first question concerning any plant was, whether it was wild or cultivated. There is no need of citing exam- ples of those hundreds of vernacular plant names the first term of which is " wild " ; but all of them, as relics of pristine botanical ages, attest the once universal prevalence of this partitioning of all things that grow out of the ground, into the two groups of the cultivated and the wild. As for Theophrastus, out of the some 500 species and varieties of plants of which he treats, only an insignificant proportion are other than domesticated ; and he says that the uncultivated things of wildwood and mountain are mostly still unknown and have no names. To have assigned space in his book for the consideration of many wild plants must have appeared like a marked innovation ; « Hist.. Book i, ch. 6. 70 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 one that indeed looked in the direction of a widening of the field of botanical investigation, and was therefore of promise for the future of the science; but it must have given occasion for carping critics to ask how wild plants, such as have neither names nor history, are entitled to a place in the History of Plants. But while this newly suggested distinction had within itself one element that would eventually accomplish its obliteration, Theophrastus did not perceive this. Among wild trees and other growths which it had been sought to introduce into gardens, there were some which had baffled every effort to transfer them, whether by root or seed. From this he reasoned that there existed a line of natural demar- cation, at least between plants that were susceptible of domestica- tion and such as were not. But some trees which he named as apparently impossible of domestication are now successfully cultivated. Having held the status of an acceptable part of botanical method for a millennium and a half, at the revival of botany in the first part of the sixteenth century this distinction began to decline in popular favor, and within two centuries more it became so nearly obsolete that, in books descriptive of the plants of particular regions or districts, those of field and garden were wholly omitted. Only wild plants were now taken note of; and so an extreme squarely opposite to that of Theophrastan times had been reached. And what lends deeper interest to these observations now, is the circumstance that of late years there has been awakened the keen- est passion for the study of cultivated plants that history has known. I speak, of course, of that purely philosophic and scientific investigation of them which' either together with or apart from the industrial in motive, engages the attention of many botanists. And here, realizing that the very father of written botany was chiefly attentive to domesticated growths, and upon these as prin- cipal subjects wrought out his scientific system, one wonders whether or not in botany the first cycle of its history is being completed. From yet another outlook over the vegetable kingdom as a whole, all the subjects thereof range themselves under the two assemblages of the ' ' flowering ' ' and the ' ' flowerless ' ' . Theophrastus records this ; but assuredly the invention of such a division cannot be ascribed to him. It must have formed a part of the universal prehistoric botany. Never since human intelligence came into the world, and lived in converse with nature, can people have failed to remark the presence here, and the absence there, of those differ- LANDMARKS OF BOTANICAL HISTORY — GREENE 71 ently shaped, differently colored, and singularly congested foliar parts that they call the flower. It must have been observed immemorially, and accepted as a nature-taught fact, that such and such trees, weeds, and other plants never display flowers. They are flowerless. What I have been careful to state, namely, that the primitive notion of a flower is that it consists of leaves, must be insisted on. The reader must not permit himself to think of the pristine idea of flowerless plants as embracing anything less than the cryptogams plus the whole body of the apetalous phan- erogams. With this fixed in our minds, we are then ready to in- quire whether or not Theophrastus made any improvements of his own upon this part of pristine botanic method ; whether perchance he looked into the matter far enough to have discovered that there exist such things as flowers destitute of flower leaves, and thereupon enlarged the boundaries of the flowering plants and correspondingly restricted those of the flowerless group. The answer must await our study of Theophrastan anthology. In close connection with his separating between the flowering and the flowerless, the Greek divides the whole plant world again into the two categories of the "fruit-bearing " and the" sterile "-1 Judged by certain criteria that are of comparatively recent adoption there would be no call for this last distinction; for the flowering and the fructiferous would exactly correspond to each other, as would also the flowerless and the sterile; so that this last seeming distinction would be but a different naming of two primary groups before indicated. But this is not true; for when we have learned his doc- trine of the flower we shall perceive that he had in mind fructiferous plants, and trees even, the flowers of which he had been unable to detect and which therefore of logical necessity he must classify as flowerless. Also, since he knew nothing of such sexual dis- tinctions as have their ground in floral structure, there presented themselves to him what we of to-day know as the males of certain dioecious plants, which flowered freely, and yet were sterile in- variably. There was, then, no correspondence at all between those two items of his method as he saw and indicated them. As regards the scientific merits of these two groupings our esti- mate must be formed according to their correspondence with the facts known at the time the groups were proposed, and not by bringing, for example, Theophrastus' groups of "flowering" and " flowerless " abruptly into contrast with those groups as they stand 1 I have inverted Theophrastus' order here. He places fruit-bearing and sterile before flowering and flowerless. J2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 in recent botany under those same names. Such a mistake as this the historian Meyer 1 must have made when he pronounced the Theophrastan distinguishing between "flowering" and "flower- less" to be "of little value." Its worth or worthlessness should have been determined — in the judgment of a historian, at all events —by the measure of its answerability to the state of knowledge actual at the time of its promulgation, and also with reference to its usefulness as an incentive to further inquiry into the nature of plants as flowering and flowerless. Or, even as the historic start- ing point in the designation of two groups, in name at least equiva- lent to Phanerogams and Cryptogams, this Theophrastan and very suggestive expression is of deep interest, and of no small value. These mere outlines of his general method must be concluded with the bare mention of some other aspects of the vegetable kingdom as it presented itself to the comprehensive and deeply thoughtful mind of the protobotanist. He discusses, and in much more than mere outline, meteorology and climatology in relation to plant life ; has chapter after chapter upon ecology and geographic distribution, and even touches more than lightly the topics of plant pathology and the transmutation of species. Vegetative Organography. Theophrastus begins his botany at the beginning. The remark is pertinent; for with recent writers it is no uncommon practice to begin somewhere toward the middle of the subject, leaving the foundations of the science out of sight. It is an easy way, avoiding as it does the difficulty and the re- sponsibility of laying down first principles. To recognize three separate realms of nature seems necessary; yet to indicate clearly the boundary lines between them is confessedly anything but easy. Theophrastus at the outset acknowledged the difficulty of distinguishing universally between the vegetable and animal king- doms, but he faced it. There was no evasion. He addresses him- self at once to the task of defining the plant as differing from the animal. And first he presents what must have been the popularly accepted method of indicating the distinction, though only to show its insufficiency for the purposes of science. Animals of whatever description have at least a mouth and a stomach. But it can not be said that all plants have roots, stems, branches, buds, leaves, or fruits. To circumscribe the plant world by listing the common organs of plants may enforce the exclusion of many things which are neither of the animal kingdom nor of the mineral, and are there- i Meyer, Geschichte der Botanik, vol. i, 162. LANDMARKS OF BOTANICAL HISTORY GREENE 73 fore plants. Here it should be remarked that well toward the beginning of the seventeenth century there were people — among these at least one very eminent botanical author — who did not allow the fungi to be classed as plants at all. Theophrastus knew all these lower forms of vegetable life, fungi both terrestrial and hypogeous, lichens and algae in abundance, and proclaimed it unhesitatingly that they are plants; plants indeed without stem or leaf or root or seed. 'The phases of plant life are so exceedingly diverse in nature and constitution that, to give a general (i. e., morphological) definition of a plant, and that in few words, is not possible,"1 he savs. He ventures, however, one distinctive peculiarity of plants. ' They are not, like animals, endowed with ethical susceptibilities and the power of voluntary action." This is metaphysical, indeed, yet no whit more so than that which Linnaeus gave in the middle of the eighteenth century when, pressed for one single mark of distinction between the genus Homo as separate from those anthropoid mammals next in rank, he was compelled to cite the " Nosce teipsum"; that is, man's consciousness of his own existence. Between animal and vegetable kingdoms the man of the eighteenth century could offer no better distinction than this: "Plants grow and live. Animals grow, live, and feel."3 But he of twenty centuries earlier had been more circumspect and cautious. Such movements as heliotropism and nyctotropism, and others seemingly akin to nervous irritability, were not unrecognized by Theophrastus, and may well have seemed to indicate something too closely allied to feeling. In defining the manifest organs of higher plants the philosopher proceeds with like caution, preferring physiological to morpho- logical characteristics; in this, the first precursor of the modern biologist, who, if required to name one distinction between plant and animal, confines himself to a point in physiology. The root, Theophrastus says, is that by which aliment is taken up4; not a satisfactory definition to us moderns who demand morphological distinctions. Yet very safe is Theophrastus in his reserve; for what he names as characteristic of roots, albeit a merely functional characteristic, is one that holds. It is also apparently a new definition, framed by himself, and intended to 1 Hist., Book i, ch. 2. 2 Hist., Book i, ch. i. I trust I may not be found to have rendered too freely the words fiOy and * Syst. Nat., 4th ed., p. 3. * Hist., Book i, ch. 2. 74 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 displace another definition which, though time-honored, was fallacious. That antique fallacious definition of a root has not yet been universally displaced. Without going quite out of sight of some of our colleges one may elicit that same old characterization of the root, and from the voices of people who have a certain familiarity with this particular plant organ. Multitudes in every land under the sun to-day will answer promptly that the root is the underground part of a plant. The Lesbian boy, while yet untaught by either Plato or Aristotle, it is most likely would have given this same answer. In maturer years, after much careful questioning of nature, he has found that that popular definition of a root does not hold good. The shrub or tree which the Greeks call Helix, the common ivy, he has observed minutely and ex- perimented with until he has established it that those threads by which it climbs rocks, walls, and tree-trunks have nothing of the nature of tendrils, but are perfect roots, exercising in some degree even the usual function of roots.1 He knows quite as intimately the shrub Ixos, the mistletoe, and that its seeds refuse to so much as sprout elsewhere than on the bark of living trees, into which bark it strikes its roots.2 He had not seen the banyan tree of the Indies; but there were Greeks, educated Greeks, who had both seen and described it, with its many lesser subsidiary trunks grouped around the large central and original one. In their descriptions the travellers had stated so definitely the origin of the| accessory trunks as starting out from main branches and growing straight downwards, that Theophrastus without hesitating declared that such things, however trunk-like they may at last appear, are roots.3 Thus did the first master of organology com- pletely invalidate the ancient world's definition of the root, and at the same time indicate with clearness the two categories of roots, subterranean and aerial. He did not, however, name them. As nomenclator of even his own most brilliant discoveries he was usually delinquent. We seem to read it between his lines that there were in his mind some suggestions of root characteristics which, had he been less cautious than he was, he might have added to that very reserved and merely physiological definition. The downward growth from the branches, in case of the banyan, and also the statement that those pendents at first and while young and tender are of a light color and hairy (!) — both these 1 Hist., Book iii, ch. 18. 2 De Causis Plantarum, Book ii, ch. 23. 3 Hist., Book iv, ch. 5. LANDMARKS OF BOTANICAL HISTORY — GREENE 75 reported facts influenced his decision that these were roots. We shall also see presently that he had noted other morphologic marks, but such as he did not think universal. The roots of herbaceous growths he in general classifies as ligneous, fibrous, and fleshy; and these include many things recog- nized in recent botany as subterranean stems, that is bulbs, corms, tubers, and the more thick and fleshy forms of root stock or rhi- zome. All really fleshy underground parts he distinguishes again as vertically elongated, spherical, depressed-globose, and what he calls nut-like; this last class embracing such incongruities as the small and solitary shell-covered corms of the crocus, and those tuberiform enlargements that appear, as if strung like nuts, on the roots of the asphodel. The rhizomes of arundo, and of what he names as arundinaceous plants in general, and which he remarks are sometimes partly above ground, he denominates jointed roots, but notices that these all have fibrous roots attached to them Others, like the bulbs of squill and onion, are composed of a multi- plicity of scales or tunics which can be removed one by one; so that these differ from other fleshy roots in that they exhibit two different kinds. Their nature is so peculiar that one might be excused for doubting that they are roots at all; for if in that they are subterranean they would at first seem to be such, they are in other particulars of quite another nature; because roots properly so-called diminish in size toward their lower extremity and end there acutely, whereas these bulbs and their like are widest at base and grow smaller in the opposite direction; moreover those fibres which descend from the bases of some and from the sides of others are the real roots which take up aliment ; but the extuberant part is more like a foetus, or a fruit.1 However, after still further discussion, he seems to rest in the conclusion that, as roots are of various kinds, and even bulbs and other fleshy roots are functionally much alike, all may well enough be continued under the category of roots. If to any botanists of the twentieth century it may seem a strange thing that the Greek, having distinguished between roots as subterranean and aerial, should have failed — and after all his study of them — to classify stems also as aerial and sub- terranean, let them recall to mind that philosophic conservatism which led Theophrastus to make more of the function of an organ than of its form; that he was sure that corm and rhizome and tunicated bulb attract nutriment and are by that token roots. i Hist., Book i, ch. 10. 76 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 Let them also contemplate the fact that for twenty hundred years and more all botanists accepted the decision of Theophrastus, and that even with Linnaeus, those organs which we have somewhat recently been learning to regard as subterranean stems were nothing but roots; and that Linnaeus in this particular was even so far back of Theophrastus that he had no doubts about their being roots. That in the most primitive phytography roots received almost singularly minute attention has been adverted to, and the probable reason assigned. Accordingly we shall find Theophrastus, when done with their morphology, anatomy, and physiology, giving a full account of their differences as to color, odor, flavor, and their qualities as wholesome or deleterious. In color, some are white, others black, not a few yellow, some tinged with red, and some quite intensely red. As to odors and flavors there is again much diversity; and some that are sweet and pleasant to the taste are deadly poisonous, while several kinds that are of disagreeable odor or bitter are harmless, and even of medicinal value. At the correct definition of a stem as being that part of a plant which bears leaves, Theophrastus did not arrive. His imperfect conception of the leaf, for one thing, stood in the way. Those merely scale-like short leaves, upright and even appressed to the stem, such as those of asparagus and orobanche, were mere scales in his view of them, and the stems of such plants he considered leafless. Again, to his vision there was a horde of stemless plants the leaves of which arise not from any stem at all, but directly from the roots. Here I can not forbear remarking that we of to-day, despite our better characterization of the stem, and our recognition of it as present in all except the very lowest plants, yet contradict our own definition in our practice, and have fallen back upon that of Theophrastus whenever we speak or write, as we freely do, about acaulescent plants and radical leaves. The ancient author defines the stem primarily as that part which is the main vehicle of aliment to the other parts ; adding that it rises up singly from the ground 1 ; which is of course to distinguish it from the branches and leaf-stalks, both of which he knew to be also channels for aliment. This definition, equally with that of the root, evinces his distrust of morphological characteristics as de- finitive, and his feeling that the physiological are safer. But, the stem once defined functionally, he proceeds with care and skill ' Hist., Book i, ch, 2. LANDMARKS OF BOTANICAL HISTORY — GREENE 77 to indicate its many morphological diversities; and here not only classifies but also names several of the classes. He acts as if he thought the language of science would be defective if such dis- similar things as an oak log, a mullein stalk, and a rye straw all were to bear the name of stem. In practice, therefore, he called the stem of a tree its trunk, ffrsAexoe, the light hollow or pithy stem of all grassy and reedy things was a culm, ndXaf^os- thus the ordi- nary word stem or stalk, xavhos, was mostly limited to designate those of what we know as herbaceous exogens; and so our modern botany has these three kinds of stems as designated by Theo- phrastus. Culm is even very manifestly a modification of the Greek kalamos. Embracing as it does almost all endogenous stems, it is more comprehensive than the English words straw, reed, and rush all combined ; and in our botany we were obliged to borrow and make over just the Greek term which Theophrastus invented — unless he, too, borrowed it; or, what amounts to the same, extended the use and gave a new and scientific meaning to an old and familiar term. As to their forms and modes of growth he distinguishes many kinds of stem among herbaceous plants. And, as woody growths are classified as trees and shrubs, according as their trunks are one or several from each root, so the herbaceous are distinguished as one-stemmed or many-stemmed. The nu- merous kinds of bulbous plants both wild and cultivated he under- stands as being invariably one-stemmed, and therefore does not speak of this in his descriptions of such; but of other herbaceous growths his custom is to mention, in his descriptions of them, whether the root sends up a single stem or many. It is a dis- tinction of importance to phytography; and if the anthological extremists of one and two centuries ago thought it superfluous, and neglected it, its value is now again beginning to be clearly seen and freely admitted. Again, herbaceous stems are upright, or reclining, trailing, climbing, or twining. 1 He also has observed that one-stemmed herbs are apt to be erect, the many-stemmed otherwise; or at least that the reclining or trailing are always many-stemmed. Among upright stems he perceives how different those of the umbellifers are from most others in that they are fluted, or at least striate, and, giving these and all their like a name that really points to their anatomical structure rather than to their external appearance, he denominates all such plants nervose-stemmed. Through having missed the discovery of the 1 Hist., Book vii, ch. 8. 78 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 good morphologic mark of stems, he is constrained to offer the category of what he calls smooth-stemmed plants. Such "stems" are nothing more or less than the flower-stalks of acaulescent perennials, called smooth stems because devoid of those unevennesses now designated as the nodes and internodes, and received as the most universal mark of real stems. His examples of the smooth stem are those of the onion and leek, 1 good illustrations of the scape, as named and denned in later organography. The leaf is a thing so almost infinitely diversified that he does not attempt to characterize it morphologically, or even physi- ologically, for he can not with any degree of certainty name its chief function. So without vouchsafing any definition of it, he goes about the rehearsal of its many aspects. Although as an organ it heads the list of that division of them which he has dis- tinguished as transitory, and therefore in a manner secondary, no part of a plant would seem more deeply to have interested him, or to have been more carefully observed. He is even somewhat diffuse in his writing upon it ; more so than in the case of any other organ, unless the fruit and seed are to be excepted; and, since the opinion now prevails almost too widely that little was done in the direction of plant organography until within the last two centuries, the interests of truth can not at just this point be better subserved than by giving the substance of this ancient Greek's morphology of the leaf somewhat in detail. " Leaves are commonly attached to the stem or branch or to whatever else supports them, by a stalklet; this either firm and holding the leaf steadily in a certain position, or else slender and feeble, allowing the leaf to hang downward and perhaps tremble with the passing breeze, or even to become inverted, turning the usually paler lower face upward. But there are also leaves with no stalklet, these adhering directly to the branch. Some leaves arrange themselves only in opposite pairs, with regular intervals between the pairs, while others are scattered singly and without order up and down the stem." It will be seen that these beginnings of Theophrastan teaching about the leaf are precisely what one finds in every primer of botany to-day. Every beginner has to be taught the importance of the distinctions between a petiolate leaf and one that is sessile, and between the opposite and the alternate in leaf arrangement. 1 Hist., Book i, ch. 16; also Book vii, ch. 7. 2 Excerpts from Hist., Book i, ch. 16. LANDMARKS OF BOTANICAL HISTORY GREENE 79 We have improved the descriptive phraseology, and are able to say the same things in fewer words; but that is about the only difference. Some general differences in the configuration of leaves are also adduced. There are those of rounded periphery, or even somewhat elongated, all without angles, and there are the angular in outline, some of them like those of the fig deeply cleft, others like those of the oak sinuated all around, still others with saw-like teeth all around; and some are sharply pointed at the apex, the slender leaves of pine and others even ending in a prickle. In certain thistles he notes that spines take the place of foliage. He is convinced that certain leaf-like organs in a number of asparagus allies are not leaves, yet he gives them no name; nor had they obtained a name — that of cladodes — even as late as the time of Linnaeus, who, as if he had been of a pre- Theophrastan age, still called them leaves. The hollow and fistu- lous foliage of the onion and some of its kindred elicited remark from Theophrastus as being very exceptionally curious. So did that of the sedges, as being conduplicate and keeled. The essen- tial characteristics of the leaf that is pinnately compound he also seems first to have detected; for he is at the trouble to argue the case before those who, as he seems to acknowledge that he himself also once did, regard this as a leafy branch. He has observed the autumnal falling of the foliage in the ash tree, elder, and sorbus, and reports that the whole of that which seems a branch falls away piece by piece, thus establishing it beyond dispute that the whole is one leaf. He even speaks of it, afterwards, as the pinnate leaf. x And, as there are kinds of tree in which leafy branches, by being somewhat lengthened and having their leaves set closely in two opposite ranks, resemble the compound leaf, Theophrastus in one place that I have noted cautions the student against being deceived. The case is that of the elm, the pinnately leafy twigs of which might be mistaken by the unwary for compound leaves. The observer is warned that the elm has but a simple leaf, cpvX\or aVjzdfV.2 The leaves of the rose bush I do not find described in Theophrastus. These shrubs were so universally familiar that description of their foliage was needless; but that he recognized this as a pinnate foliage is evident by one comparison that he makes. Wishing to convey some notion of the leaves of an inter- esting tree of the Orient (Tamarindus Indica, Linn.), he says it is "many-leaved, after the manner of the rose bush,"3 meaning that 1 Hist., Book iii, chs. u, 12, 13, and 16. 2 Ibid., ch. 14. 3 Ibid., Book iv, ch. 9. 8o SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 the individual leaf of the tamarind tree is of many leaflets, like that of the rose. The philosopher devised now and then a new botanical term, but did this with reserve; and the discovery of compound leaves does not appear to have called, in his thought, for any such distinction as that of leaf and leaflet. He applies the term leaf, (pvXXov, to the compound leaf as a whole, and to the individual leaflet indiscriminately. As regards the differences of compound leaves and the classification of them he did nothing; nor, indeed, does anything appear to have been attempted in this direction, after Theophrastus, until the time of Jung, who in the middle of the seventeenth century strongly advanced the morphology of the leaf. But Theophrastus in his environment can not have met with anything like that diversity of compound leaves with which Jung was familiar. He must have known the bipinnate fronds of certain ferns, but did not essay any description of them; and when a certain bipinnate-leaved tree from Egypt (Mimosa polya- cantha, Willd.} was in need of a description, he evaded the difficulty of the situation by saying that its leaves were like those of a fern.1 We shall be furnished later with some proofs that the venerable Greek could make significant discoveries in connection with such very little things of the plant world as small apetalous flowers, and even the inner structure of small seeds. Without microscope, hand lens, or spectacles, he seems to have been almost microscopic- eyed sometimes, as well as always alert for the detection of the exceptional or unusual in the grosser morphology of things. We therefore wonder that, after his having noted so carefully that some leaves, even small ones, are compound and even doubly compound, he should not have taken stipules into account; for he makes no mention of them. During it may have been fifty winters he had seen the branchlets of the plane trees under which lay his daily walks, encircled at intervals by their wheel-shaped stipules still persistent after the body of the leaf had fallen. During as many summers of his centenarian career he had observed the foliage of many garden leguminosa?, in some species of which every- where in cultivation anciently, more than half the foliar area is stipule; and yet this organ is unmentioned by Theophrastus. As to its presence on the boughs of the most common Athenian way- side shade tree, and its more conspicuous showing amid the herbage of every sort of pea and vetch and lentil, this father of plant organography is as silent as if the organ had not existed. This 1 Hist., Book iv, ch 3. LANDMARKS OF BOTANICAL HISTORY GREENE 8l seems anomalous. To the average reader it will seem like a curious hiatus in the Theophrastan leaf-morphology. The situa- tion seems nevertheless readily to explain itself. One has but to recall to mind the ancient botanist's strong inclination to regard function first and form last everywhere in his organography. The excessively enlarged and leaflet-like stipules of Pisum and some other leguminous herbs have not the least appearance of being functionally different from the other leaflets. They are larger and also located a little differently from the others, but that is all; and there is the best of evidence that a thorough training in modern organographic refinements is requisite to the determination of the enlarged basal leaflets of the pea- vine as stipules. The evidence is this: that the most original and logical of great organographers and terminologists, Joachim Jung, as late as the year 1662 of our era knew nothing of any such organ as a stipule. Tournefort in the year 1700 knew them not, and Linnaeus claims them as among his own organographic discoveries, though unwarrantedly, as we shall see later. There is, however, one particular kind of stipule which, unless I misunderstand Theophrastus, drew his attention and elicited his comment. It was a case in which there is about the strongest possible contrast in appearance between the leaf proper and the stipular appendage; that of certain umbellifers in which while the decompound blade is deep green and almost capillarily dissected, the large stipular development below it is pale, membranaceous, wholly uncut, sometimes cup-shaped and hollow. Here again it would seem to require our modern refinement in organography to perceive in such a thin bladdery stipule and green capillarily cut blade the different parts of one and the same organ. Theophrastus, at all events, knew some umbellifers of this description, and wrote concerning one species of the genus Ferula that it puts forth at the nodes of its stem leaves and ftXaffroi.1 The blastoi, one from each node of the stem, have perplexed some of the botanical commen- tators upon the text. I think they are the stipules. If Theophrastus does not anywhere formally define the leaf, that may have been for the reason that, not at all comprehending its function, it was not possible for him to define the organ, as he had defined root and stem, physiologically. Nevertheless he did state, in a most informal way, its very best morphological mark; that by which it is almost always readily distinguishable from a i Hist., Book vi, ch. 2. 82 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 stem or any part of it. He observes that most leaves have an upper face and a lower. The upper, exposed to the sun, he notes as being of a deeper green and smoother; the lower face is paler, roughened by the greater prominence of the veins, and apt to be pubescent.1 From the fact that the lower face of leaves when pubescent is found to be moist he says it has been inferred that it absorbs nutriment and feeds the rest of the leaf. This he confi- dently declares to be erroneous, affirming that all parts of a leaf are fed by way of the veins and fibres which are carried to every part, and which he knows to be connected with the bark. This was the thing which he could easily demonstrate and prove. The other proposition was not in his day demonstrable; for he could not know either the structure of a plant hair, or the existence of stomata. Theophrastus, like his class in all ages, is likely to be correct in that which he affirms, and wrong as to that which he denies. Anthology. Without any understanding of flowers as organs of sex, and quite in the dark as to their significance in the economy of plant life, Theophrastus applied himself assiduously to the study of their morphology, and that with a measure of success compelling the admission that he is the founder of anthology; for several of his distinctions remain fundamental in the anthology of to-day, notwithstanding that the theory of the flower has been completely revolutionized within the modern period.2 And his success is the more remarkable because of his having made his researches at a time when, for mere lack of optical equipments, the discovery of the functions of the essential floral organs was impossible. From ages antedating all history cultivators must have ob- served that in such trees, garden shrubs, and herbaceous field crops as flower conspicuously, no fruit or seed develops but as an aftergrowth from the flower; that a young tree never fruits until after having for the first time flowered, and that any mischance befalling the flowers of the tree in their season extinguishes, for that year, all hope of fruit. Upon a considerable array of facts of this kind, the first philosophic investigator who came along might naturally propound such a theory as this, that wherever there is now a fruit or seed, at some time there must have been a flower; a proposition which the cultivators at once and with one voice would have disputed; for in the husbandry of antiquity no tree was more esteemed, nor any more familiarly known than the fig 1 Hist. Book i, ch 16. 2 Namely, by Sebastian Vaillant, De Stnictura Florum, Paris, 1717. LANDMARKS OF BOTANICAL HISTORY — GREENE . 83 tree, and this, as all the world understood, produced its fruits two crops a year, without a trace of flower. And Theophrastus, after all his searching for and philosophizing about flowers, seems to have found no way of controverting the universal opinion. He thought that the fig produces its fruit without flower of any de- scription.1 But in his philosophic quest for flowers of some sort as the forerunners of all fruits and seeds, he appears to have dis- covered true flowers, though sometimes recondite, in other trees that had been supposed to be like the fig, flowerless. The flower, in prehistoric thought and speech, may most reasonably be as- sumed to have been a thing showy on account of its being made up of leaves colored differently from ordinary foliage, and differently arranged. It must have been essentially that which modern botany knows as a corolla. This inference as to what a flower was before either botany or history began to be written is confirmed by our experience with untaught rustics and mountaineers of to-day, as to their understanding of what trees and plants have flowers and what have none. They are the modern counterpart of those unlettered ruralists of remote antiquity whom Theophrastus cites as denying that oak and walnut trees, hazel bushes and chest- nut trees and junipers have any flowers at all.2 The philosopher, the man of science who is truly such, has this among other char- acteristics, that with him negations are apt to go for naught. Of the populace they are largely the mental stock in trade, so to speak, but himself negations do not satisfy. They say that neither oaks nor hazel bushes have flowers. They recognize it that oaks put forth clusters of loose pendulous tassels that they call oak-moss, and also globose bodies denominated galls; but oak-moss is not a flower, any more than oak-galls are acorns. These are specimens of the facts, and of the reasonings upon them, which confronted the protobotanist of so long ago. Stimulated by the thought that almost always where a fruit or seed now is, there was once a flower, from the very heart of which the fruit or seed took its origin, he enters upon his researches. Now this very idea that flower and fruit are related as antecedent and consequent so that where any manner of fruit or seed is found the essentials of a flower must be sought, is the germinal idea out of which the whole of systematic 1 Hist. Book ii, ch. 6. There is but one record of the discovery of the flower of the fig until after the invention of magnifying lenses, and some eighteen centuries after Theophrastus. Even Linnaeus, still later by two centuries, had the genus Ficus under the Cryptogamia. 2 Hist., Book iii, ch. 6. 84 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 botany as we have it has been engendered; and the originator of that idea would have been the father of botany even if he had accomplished nothing further. There is one thing which he who would know, even in outline only and superficially, the history of botany, must not do. When in Theophrastus he meets with the word avdo*, or in Pliny with the term "flos," he must use care not to read into that term the meaning which the word flower has in modern botany; for, if he assume that the word stood, with those authors as with us, for a congeries of four circles of different organs, beginning with the calyx and ending with the gyncecium, he will never correctly appre- hend a word they say about the flower. That view of the com- prehensiveness of the flower which we now take, extremely unlike the ancient idea, was really first presented for acceptance within somewhat less than two hundred years from the date at which I write. The flos of remote antiquity, the pre-Theophrastan anthos, appears to have been simply the corolla, as we have said before; and that without a special name as such. It was but a set of leaves, shaped and colored and arranged differently from ordinary foliage, and having for its function the protecting of the future fruit and seed while in their tender and rudimentary stages. Now oaks, walnut trees, alders, and hazels have no corollas. They had been considered flowerless because they have none, and correctly enough so long as the flower was defined as a whorl or tuft of specially altered and colored leaves; and it was so defined in the minds of the majority of people in that time, as it is in the minds of untold thousands in every land to-day. And the very possibility of detecting upon oaks and filbert bushes some small thing that should mark the point of origin and presage the coming of each nut and acorn involved the possibility of a revolution in the idea and definition of a flower; an extension of the term, to make it embrace anything, no matter how colorless, shapeless, and obscure, which should be found in the place where a flower ought to be. This earliest Historia Plantarum, intensely interesting though t be as we have it, would have been still more so had its author given some record of his own processes of research; his successes and his failures in attempting to find flowers on trees and herbs that had the reputation of being flowerless. But the traditions of the lyceum at Athens were against that. Men were taught that knowledge is best communicated in language concise and brief; and Theophrastus' three short chapters of anthology may vie with LANDMARKS OF BOTANICAL HISTORY — GREENE 85 any other three chapters of scientific matter ever written, in respect to the terseness and brevity with which important propositions follow one another in close succession.1 His first proposition as to the general morphology of the flower is this: "Some flowers are capillary, like those of the grape, mulberry, and ivy; others are composed of leaves, like those of the almond, apple, pear, and plum trees." These are trees; but he proceeds to say that quite the same is true of the flowers of herbaceous and annual plants, some of which have foliaceous flowers, others capillary. It is evident as can be that by examining the earliest germs of fruit in plants that never show flower-leaves, he has found those fruit-germs at a certain early period encircled by hair-like or filamentose things quite as transient as flower-leaves, and which seem in some way to take the place of them, though they have not always the usual special coloring of flower-leaves. On the strength of what he has studiously observed, he has now virtually given to the term avdos, flower, a new definition, a scientific one. The term must embrace whatever is intimately though transiently connected with a fruit- germ, whether laminal and colored or filamentose and greenish. This, in so far as written records show, is the earliest proposition ever laid down concerning the morphology of the flower ; and it was a mighty contribution to scientific botany. It is in substance the distinction of petaliferous and apetalous flowers. It will therefore hold its place in the science of plant life and form as long as such a science shall exist. The investigations of Theophrastus along the line of what we denominate apetalous flowers appear to have opened his eyes to the presence of the capillary organs in a large and showy petaliferous kind; for in this same chapter he states that many flowers are two- fold, showing another flower inside the main one. He cites such familiar garden flowers as the rose, violet, and white lily as ex- amples; and, as against any suspicion of ours that his twofold flower of rose and violet and lily might mean a double flower, as composed of multiplied petals within the main outer circle, there occurs the one word SIX/JOCK, two-colored, or differently colored. It is, of course, the stamens within the corolla of red rose, purple violet, and white lily that are colored differently from the corolla. This is the earliest recognition of the flower as other than a simple organ. It is the beginning of the classification of its parts; a small beginning, but highly significant. It is given out for the first 1 Hist., Book i, chs. 20, 21, 22. 2 Ibid., ch. 21. 86 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 time, that many flowers have two circles of organs, a flower within a flower, the one within readily distinguishable from the broad, |eafy one outside. He does not formally name this inside flower, qut he has found so many flowers that lack the leafy outside circle altogether, displaying nothing but the inner, that he names this kind capillary or woolly flowers. It must here be affirmed that Theophrastus knows nothing of the calyx as being any part of a flower. The color and texture of floral organs were what distin- guished them from ordinary foliage; and by their points of agree- ment with the latter any green leaf-like organ or circle, however near the "flower," would fail to be included as a part of it. Also the ovary and ovules were not indicated or received as organs of the flower. They were simply the fruit or seed, in whatever stage from that of the flowering to that of full maturity; and this neither through dullness nor indifference. The colored leaves, together with the colored threads, set in the midst of them, were all there was to the flqwer. One may fancy some brilliant Greek pupil asking the master if that protuberance in the middle of many flowers ought not to be regarded as a part of the flower, and called the fruit, ought not to be called by a name of its own while in the flowering stage. He who knows the keenly penetrating and severely logical mind of Theophrastus will infer without chance of a mis- take, what the substance of his answer would have been. At what particular point in its development will that protuberance begin to be a fruit? I suppose that such logic might silence the ablest morphologist who has lived hitherto. Our modern term ovary is but an illogical convenience. It suitably abbreviates the follow- ing expression: " fruit at the budding or flowering stages and for an indefinite period thereafter." Our neighbors the industrial bot- anists even of to-day have no need of the term ovary and ignore it. When a hard unseasonable frost has sterilized the ovaries of their trees, whether in bud or inflower.it is the "fruit" that has been killed ; and so the Theophrastan anthology still lives and is widely though unwittingly approved. What are now known as the styles were not segregated from the other flocci, or capillamenta — that is, from the stamens — until ages after Theophrastus. He made no distinction between these two, at least when found together within the same flower; and his capillary flower might consist of stamens alone, or of styles only, or of both. What is more, there are certain arrangements of stamens under which they failed to gain recognition by him as being of the nature of floral parts, as in the aments of hazel, the LANDMARKS OF BOTANICAL HISTORY — GREENE 87 walnut, the oaks, and many more. He gave them a name, iovkoij- Latinized as juli, writing about them so minutely and describing them so well as to attest his perfect familiarity with them; but apparently the more he studied them the more enigmatic did they seem.2 The filbert, Corylus av ell ana, not only grows wild in Greece, but it had been cultivated there doubtless for ages before Theophrastus' time. It would be irrational to question that it was among the shrubs of that botanic garden in the midst of which lay his daily walks for many years. At all events, his perfect fa- miliarity with its tassels is attested by the following account which he gives of them. " In autumn after the nuts have fallen, there appear in bunches of several certain things that look like worms, inserted on a short thick stalk. These are called juli. Each is made up of countless scales arranged somewhat after the manner of those of the nut pine (Finns pinea, Linn.), the whole longer in proportion to its thickness than that, and also of equal thickness throughout. Before the end of winter it begins to grow. In early spring the scales separate and stand apart, and are then become yellow, the whole then sometimes as much as three inches long. When the leaves begin to put forth, these things shrivel and fall. Then the cups that enclose the nuts develop; one cup for each flower, and one nut in a cup." The concluding sentence places it beyond doubt that the writer knew the crimson pistils of the shrub as well as he did the yellow aments. He does not stop to describe them. They are of his class of capillary flowers, and that is enough. In a later chapter,4 in which he brings out the habit and vegetative characters of the filberts, indicating twro species (C. avellana, Linn., and C. tubulosa, Willd.) by differences of fruit, he has no occasion to mention again the flowers, but can not forego renewed allusion to those per- plexing aments. ' To these shrubs belong that julus of compacted scales which we have elsewhere described." The sterile aments of the oaks, slender, lax, more tufted than those of the hazel as well as of short duration, must also have been known to Theo- phrastus ; and so were the colorless and very inconspicuous pistillate flowers; for, while he quotes the popular opinion of his time that 1 Hist., Book iii, ch. 7. 2 Pliny, some three centuries after Theophrastus, refers to the juli of the filbert in terms that prove them still incomprehensible to nature students of the time. He says they are ad nihil utiles; which we remark is a negation, and therefore unscientific. 3 Hist., Book iii, ch. 7. * Ibid., ch. 15. 88 SMITHSONIAN' MISCELLANEOUS COLLECTIONS VOL. 54 these and other like trees are flowerless, he tersely contradicts it. " Both oaks and alders flower " *• ; by which he must have meant the axillary and scattered pistils of the oak, and the cone-like clusters into which the alder pistils are congested. Of the aments of fir and pine I observe no mention in Theo- phrastus. Even the young cone of pistils with their subtending scales in the conifers, from its form he denominates a julus; but it is not of the enigmatic class. Without hesitation he denominates that the flower. It is also plain that with him this must be re- ceived as a petaliferous or leafy flower, for it shows nothing that could be called a capillamentum. The rudiment of each fruit rests in the axil of an ample and highly colored leaf. 2 Nor does he here cite the opinion of any of his forerunners or contemporaries as having denied or questioned that these are flowering trees, as they had done in the case of oaks and alders and hazels. The flowers of the fig tree he could never discover. To him it was as flowerless as a fern or moss. He was loath to believe that junipers are not equally flowerless. He had investigated them ; had observed that in summer their fructiferous branches bear one set of fruits full grown, and another set newly formed and not half grown; a proof that its fruits require a year and somewhat more for their growth and ripening. He can hardly have failed to see the stami- nate aments, small though they be, and of brief duration. They were nothing, in his view; at least nothing floral, and not worth mentioning after he had once described the like phenomenon as conspicuous and of long duration in other trees and shrubs. What he was looking for, he could never find, that is, what he would have accepted as a flower, a folium, or a capillamentum indicating the seat of the juniper berry that is to be. The pistillate or fertile juniper flower is as far away as it is possible to go from having the appearance of a flower at all. It shows even under a lens no trace of style or stigma or ovary. It is so little different from the minutest first rudiment of a merely vegetative twig, that an ex- perienced botanist, even of these later times, may fail to recog- nize it, though he search with a lens. It is improbable that there is a man in the world to-day who, in the feeble botanical light of the Theophrastan age, and without the aid of magnifiers, would ever have found the pistillate flower of a juniper. ' Hist., Book iii, ch. 5. 2 "The flower of the fir is yellowish red, and otherwise beautiful." —Hist.' Book iii, ch. 6. LANDMARKS OF BOTANICAL HISTORY GREEXE 89 But what is fully as interesting as Theophrastus' failure to find anything upon a juniper tree which he could demonstrate to be a flower, is his recording the opinion of those who think differently. "There are those who say that the juniper tree is of two kinds, one that flowers and bears no fruit, and another that is flowerless but fructiferous."1 The pronouncement is interesting as being diametrically opposed to the Theophrastan doctrine that nothing not in immediate juxtaposition to a fruit rudiment is to be re- garded as a flower. It is a virtual contradiction of the opinion that juli or aments can not be flowers. These people who held that male and fruitless juniper trees have flowers, and that fertile ones have none, were people who evidently regarded those small eva- nescent yellow, dusty male aments of the juniper as true flowers , even the only flowers that any juniper ever has. If evidence were elsewhere wanting to prove Theophrastus a true philosopher and scientific man, devoted to the truth whatever that may be, rather than to his .own theories, it is not wanting here. He publishes this adverse opinion of his neighbors for the very reason that it may possibly turn out to be the right opinion, concluding the whole passage with the recommendation that investigation of the subject be continued. "The matter should be looked into further."2 Quite as briefly as he had indicated the distinction between leafy flowers and capillary does Theophrastus give the suggestion that the leafy flower in certain plants is made up of but a single leaf.3 It is practically classifying corollas as choripetalous and sympeta- lous. He writes of what he calls the monophyllous flower as if within the field of his observation it had been somewhat excep- tional ; and he warns the reader that it is not always distinguishable at a glance from the other kind. Viewed as to their periphery they will seem to be made up of separate leaves, but at the center or base they are seen to be monophyllous. In the morning-glory (Convolvulus sepium, Linn.), however, the monophyllous character is readily apparent, only a certain angularity of the periphery re- maining in place of the appearance of separate leaves. Even small flowers may be monophyllous. Such are those of the olive tree. Lying on the ground under the trees they are readily seen to be perforate. From his having cited the olive blossom, one is assured that he held a corolla to be monophyllous even if the leaves were united only at base. But one must guard against mentally » Hist., Book iii, ch. 6. 2 Ibid. > Hist., Book i, ch. 21. 90 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 attributing to him any general recognition of all sympetalous corollas as being such as that to which later generations have arrived; for evident1 y he had not proceeded far along this line of anthological research, but was only at the beginning of the subject. Having so perfectly settled the monophyllous structure of the small and quite choripetalous-looking olive blossom, we are disap- pointed that he has not done as much for that of the elder tree. It is a tree in which he has manifested a special interest, and with which he has grown very familiar. The thin wood of its shoots and branches, along with an extraordinary development of pith; then externally the remarkably long internodes, and the foliage, from watching the falling of which in autumn he seems to have learned the very important classification of leaves as simple and compound — all these aspects of Sambucus he has noted fully. Will he not perceive that its flowers, like those of the olive, are of that structure which he designates as monophyllous ? They are too small; much smaller than those of the olive tree; even quite minute to one who is without a lens; and Theophrastus may not have ex- amined them very carefully as individual flowers. Either that, or else, in condescension to popular usage, he permits the corymb or umbel of small flowers to pass for a flower. And so he describes the blossoming of the elder thus: "The flower is white, composed of many small ones all white, the whole with the appearance of a honeycomb, and attached to the summit of a shoot by a number of stalks. " There is another type of monophyllous flower not as small, which first and last remained to him an enigma. It was the ovate, hollow, and pitcher-shaped corolla of Arbutus unedo, a most common type among ericaceous plants. He says it is not a leafy flower; an expression equivalent to the modern phrase apetalous flower. He describes it as being in the form of an egg-shell with one end cut off, leaving an aperture.2 He can not have detected the five obscure recurved teeth at the orifice; for they would have taught him that this, like the faintly five-angled morning-glory blossom, is of five almost completely united leaves. One chapter of the Historia opens with a sentence like this: " Flowers differ in respect to their origin and insertion. " 3 It is one out of a number of Theophrastus' brief statements of significant fact, any one of which would have rendered famous any herbarist of the sixteenth century or the seventeenth who had been privi- i Hist., Book iii, ch. 13. 2 Ibid., ch. 16. 3 Hisl., Book i, ch. 22. LANDMARKS OF BOTANICAL HISTORY — GREENE 91 leged to announce it as a discovery of his own. In the most recent and approved taxonomy of flowering plants, this point^in^ an- thology, first indicated by the ancient Greek, holds a most con- spicuous place. Let the Greek himself explain what he means by the origin and position, or insertion, of the flower; always keeping it in mind that with him the leaves and the thread-like parts in their midst are all there is to a flower, the ovary be ng the fruit. " Some produce the flower around the [base of the] fruit, as do the grape vine and the olive tree. ... In the greater pro- portion of plants the fruit thus occupies the center of the flower- But there are not wanting such as support the flower on the sum- mit of the fruit, as do the pomegranate, apple, and rose, all of which have their seeds [ovules] underneath the flower. A few bear the flower on the summit of the seed itself, such as the thistles, and all that have their flowers in that manner crowded together." It is a clear distinguishing between the hypogynous, perigynous, and epigynous in floral structure; clear notwithstanding that the one example brought forward to illustrate the epigynous insertion, that of the flowers of the composites, was not from the modern point of view well chosen; because then what he understood to be the seed we regard as a fruit. If he had been accustomed to assign names to what have proven to be his great discoveries in anthology, he would have called this third mode of insertion the epispermatous. He learned this springing of the "flower" from the top of the "seed" to be characteristic of the whole family of the umbellifers, and of the few rubiaceous plants that he knew, as well as of the thistles and their kindred. It seems to me that what is more to be wondered at in Theophrastan anthology than his distinguishing of the hypogynous, perigynous, and epigynous modes of insertion, is the fact of his having made out so positively, that the head in the composites is not a flower, but that it is a dense cluster of separate and distinct individual flowers, each complete in itself. Less than three generations ago, eminent systematists were still writing up the scales of such involucres as "sepals," the whole involucre as a "calyx," and the circle of ray flowers as the "corolla." At this juncture the sublime old Greek will appear to have lived before his time by more than two thousand years. In his study of flowers the arrangement of them was not un- noticed. He observes that in most trees they appear as scattered on all the branches, all appearing nearly simultaneously, so that the flowering period of such is but short. In many herbaceous and half-shrubby growths they are clustered together; and in 92 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 describing such plants as to their flowering he makes frequent use of terms equivalent to spike, raceme, and umbel, though not with such definiteness of meaning as they convey in modern botany. In these clusterings it is observed that the flowering of the whole cluster at once seldom takes place; that usually the lowest flowers are first to expand, then those next above them, this succession continuing in some plants so long that the seeds from the basal flowers are ripe before the terminal flowers have opened. The aromatic garden herb ocymum is named as a case in point;1 but he mentions this kind of inflorescence repeatedly. He also names one plant whose flowering begins at the top, the succession of later bloom following downwardly. Thus is Theo- phrastus again a botanical discoverer. He has distinguished between the centripetal and the centrifugal in inflorescences. The historian Meyer was surprised at this, remarking also that he knew of no other botanist's having noted this distinction again until the time of Link and Robert Brown.2 It is evident that Meyer pondered the fine picture books of his compatriots of the sixteenth century, Brunfels, Fuchs, and Tragus, to the neglect of the one real botanist that there had been among them all, Valerius Cordus. Fruit and Seed. Without fully appreciating the significance of truit and seed as furnishing the best clew to plant affinities, Theo- phrastus nevertheless studied them assiduously. Even flowers in their beauty and fragrance, and by their multitudinous forms, engaged him chiefly as being heralds of the fruit and seed. The perfecting of fruit he alludes to here and there as being the culmi- nation of the plant's existence. He notes it that even such vig- orous and enduring things as trees and shrubs shorten their life period by excessive fruit-bearing; that myriad annuals live but the length of one summer season because they exhaust all their vitality in the yielding of their one crop of seeds. Seeds were of very special interest, in his view; and succeeding generations of botanists have been with him in that opinion. The scientific examiner of even commonest objects finds more things in nature than there are names for in common language. The investigator of things is therefore obliged to be the inventor of new terms; and every science has therefore its vocabulary of special terms, every one of them necessary to the science and to the man of science, but to the world at large useless. In connection with his study of seeds, Theophrastus was obliged to invent ne i Hist., Book vii, ch. 3. 1 Meyer, Geschichte der Botanik, vol. i, p. 166. LANDMARKS OF BOTANICAL HISTORY GREENE 93 terms, and to give new meanings to old ones. Most seeds were grown and perfected under some special covering formed to shelter, contain, and nourish them until mature. For particular kinds of such coverings particular names were in common use: pod, husk, chaff, shell, and for succulent or fleshy coverings of seeds pome, berry, acine, or more comprehensively, fruits. A general term which should include all these coverings was needed, and the word peri- carp was coined.1 This done he defines a fruit scientifically. It consists of a pericarp and the seed or seeds which it encloses. Henceforward, while in agriculture, gardening, domestic economy, and the world's commerce a fruit is what it always was, in botany the term has another meaning, a meaning at once more exact and more comprehensive ; and it has this new meaning ' universally, and from Theophrastus forward; for modern botany reiterates it from him, unaltered by a syllable; and that of the future will do the same. In practice he did not always rightly distinguish between pericarp and seed. Lecturing upon the fruit, and having a mature sprig of sage or other labiate in hand, he would have taught that the four black nutlets are the seeds, and that the green calyx is their pericarp. Or with a handful of spikes of wheat or barley before him, he would have mistaken the grains for mere seeds, and the chaff for the pericarps. Errors like these in the mere application of his terms were inevitable. They could never have been corrected without microscopically aided vision; and it was indeed a long, long time after the invention of the microscope that botanists first learned the structure of sage nutlets and wheat grains to be that of fruits and not that of seeds. About pericarps he seems to have observed everything that lay before him within his own limited field. He notes the extreme diversity of them, but, as usual with him, and doubtless for want of time to correlate and classify he gives to the most distinctive kinds little more than an informal mention. Only a single de- duction does he Venture concerning pericarps in general as unlike other organs, a deduction superficial, curious, geometrical: "No pericarp shows a rectilinear or angular circumscription."2 Yet the cursory reader of the main chapter on fruits — perusing it in the Greek original — might well wonder with what justice or propriety it can be said that the philosopher did not carefully and effectively generalize about seed in relation to pericarp, when he finds him 1 Hist., Book i, ch. 3. wepiKapiriov was also in use with Aristotle. The invention of it lies between him and Theophrastus. 3 Ibid., end of ch. 18. 94 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 using over and over again such exceedingly important taxonomic terms as angiosperm and gymnosperm. The fact is, he employed neither in anything like that breadth of meaning which they convey as used in later botany; but both of them very restrictedly. He used angiosperm only to designate one particular circumscription of what are known with us as capsular fruits, namely, the sub- globose or urn-shaped or vase-like kinds. The example given is "that of the poppy and those like it." It is corrrelative with Ao/ftoV, the Theophrastan name for all leguminous fruits. His gymnosperms include nothing really gymnospermous in our taxonomic use of that expression. By the examples cited, " cori- ander, anise, fennel, cyminum, " and several others among kitchen- garden plants, the gymnosperms were the umbellifers. They were naked-seeded to him, because, as already noted, he had not recog- nized any such organ as a calyx; one nowhere in all the plant world more recondite than in the umbellifers. The only real gymnosperms — according to our application of the term — which he knew, were the conifers; but they do not enter, with the um- bellifers, into his category of that name. He expresses distinctly though modestly the idea as his own that, as to fruit and seed these stand naturally aloof from all other groups, and thinks the view may be tenable that cones are not fruits at all. " No trees bear capsular fruits, unless you can call a cone a capsule; but it is pos- sible to regard the cone as different from a fruit." Under the head of anthology it was seen that the cone-scale at its flowering stage was a flower-leaf in Theophrastus' understanding of it. Logically, therefore, he would have regarded it in its maturity as a sort of pericarp. But that he left the cones in a place apart, as unclassifiable with other seed vessels — the types of what were to be named gymnosperms twenty centuries afterwards — is yet another evidence of the profound sagacity of the protobotanist. After these things, it is no longer with any surprise that we read his accurate descriptions— descriptions of them from center to circumference — of such fruits as the drupe, the pome, the nut, fig, pomegranate, and other types, and citing as he always does familiar examples of each different kind. But that he should have been as near as he was to a systematizing of the placental attachment of seeds within the pericarp is again almost startling; for when he records it that in many the seeds are as it were pro- miscuously crowded within the pericarp, while in others they are ranged in regular lines, or at least in separate groups — of which latter he says the squash, cucumber, and apple are examples — we LANDMARKS OF BOTANICAL HISTORY GREENE 95 know that he has been carrying on research in this direction, and has been able to make this fair beginning at discriminating the different modes of placentation. The foundations of the whole philosophy of higher plant life and form center in — are concentrated within, if one may so speak — the seed. In botany no less than in zoology is embryology indis- pensable to a right understanding of the interrelations of things. From the minuteness of his researches into the structure of seeds and the behavior of seedlings, it almost seems as if Theophrastus may have realized this fact. He records many observations on them in all, even their most familiar aspects, not neglecting the diversity of them as to form and coloring. l In a few terse sentences he gives the results of what may have been years of investigation in his botanic garden, upon the subject of the different periods of time required by the seeds of different plants for their germina- tion. "Ocimum, blitum, eruca, and radish are most prompt of all, for they come up on about the third day after the sowing; lettuce on the fourth day; cucumber and squash on the fifth or sixth; anise on the fourth, pepper-grass and mustard on the fifth; beets sown in the spring, on the sixth, in the fall, on the tenth day, orache on the eighth, cabbage on the tenth." Leek and shallot are such close congeners that he evidently expected they would agree as to the time required for their germination, but he finds the seed of shallot coming up at the end of from ten to twelve days while that of the leek takes nineteen or twenty. More than thirty days must be allowed, he says, either satureia or origanum, and forty for celery. After long experience he finds it remarkable that the most favorable conditions as to the season of the year and the state of the atmosphere do not shorten the usual time required for the germination of any kind of seed, though a cold atmosphere, con- curring with clouded skies retards it.2 These studies in seeds and seedling plants, though by chance interesting and instructive to the gardeners of his time, are essen- tially those of a great botanical philosopher, with whom not the smallest fact relating to plant life is held unworthy to be placed on record. And as he proceeds, the twentieth-century botanist will be apt to read with amazement a passage like the following as occurring in Theophrastus. " Some seeds in germinating put forth their primary root and leaf from one and the same point; others, the root from one end and the leaf from the other."3 Pre- 1 Hist Book vii, ch. 3. J Ibid., ch. i. 3 Hist., Book viii, ch. 2. 96 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 serving all the terseness and brevity of the original in this very literal rendering, the statement of the fact may seem a trifle ex- aggerated. The first roots issuing from a grain of wheat or barley appear not quite from the base, but from near it, and the first leaf appears from a point well toward the summit of the grain. The two do not, as in dicotyledonous plants, come forth from the same point. But thus early in the history of botany, even by this first forefather, was given in these words, the first hint of a fundamental distinction between flowering plants as dicotyledonous and mono- cotyledonous. By way of further elucidation he continues: :' Wheat, barley, rye, and all the grains sprout from both ends; that is to say, the basal and thicker end of the grain puts forth the root, the upper and narrower end the green herbage. The two, however, are connected and continuous as one. But neither the bean nor any other seeds of leguminous plants have this way of sprouting. These put forth root and stem from the same point, namely, that at which the seed was linked to pod, as if under that point [the hilum of later terminology] lay the special seat of the growing principle. In the case of seeds of this kind the root at first appearing begins to show a downward tendency, the stem an upward. The seeds of the frumentaceous and the leguminous kinds are alike in this one particular of sprouting from the point of insertion; but of certain trees, the almond, walnut, the oaks and their allies, the seeds sprout from the opposite end." I have omitted here one of the most important clauses; that in which he indicates his having observed in the bean and lupine allies the two cotyledons, joined to the hypocotyle.1 Later in the same chapter he states without simile or comparison the same char- acteristic. 'The seeds of all the latter," that is, of the particular trees he has mentioned, and of the leguminous herbs, " are in a manner two-parted." And again: "Wheat and barley make their first appearance with but a single leaf, peas and beans with several" ; from which it is manifest that he counts the cotyledons as leaves, along with the one or two that appear in the plumule. Still other facts and phenomena observed and recorded by him about ger- minating seeds, and young seedlings, must enkindle toward Theo- phrastus the wondering admiration of the most accomplished modern botanist. He says that he finds it uniformly true, what- ever the kind or the structure of the seed, that the "root" is first to appear, after that the leaf or leaves; also that the cereals, while 1 In Latin the clause runs thus: "Id quod in quibusdam partis pudendae refert formam, ceu in faba et cicere, sed maxime in lupino. " LANDMARKS OF BOTANICAL HISTORY GREENE 97 as yet showing but a solitary primal leaf, exhibit quite a tuft of roots, these all simple and equal, whereas the two-parted seeds in their germinating exhibit several leaves and but a solitary "root." Furthermore he notes that the grains with their multiple roots send up culms that never branch, while the merely tap-rooted legumi- nous herbs exhibit stems that branch freely and widely. To the beautiful work of a Malpighi one gives somewhat, more credit than is fairly due it, until one has read these chapters of the ancient Athenian master. Then it is clearly apprehended that the man of the seventeenth century may have received the sug- gestions of his own work directly from the Greek philosopher; and is almost ready to add that the beautiful drawings of sprouting grain adorning Malpighi's folio might almost have been done from the Theophrastan descriptions of the same. It must needs be conceded that the botanic garden at Athens, founded by Aristotle, and the earliest of which there is any record, was wonderfully prolific of new botanical facts of profoundest import. What later one has equalled it in supplying first principles to botany as a science ? Or who since Theophrastus has used an opportunity of that kind so immensely to the advantage of succeeding generations? Anatomy. Immediately after having enumerated the principal external organs of plants, and given the first outline of a system based on these, Theophrastus takes up the subject of internal structure. Two short chapters contain the simplest elements of plant anatomy, as he is able to make them out. If these chap- ters commend themselves to our most careful reading, it is partly because they are the earliest in which such matter was discussed, and partly for the reason that after the writing of them some eighteen centuries elapsed before another botanist resumed the topic. Apparently having in mind all forms of plant life except the lowest and simplest, he opens, the subject with the statement that "plants are made up of bark, wrood, and pith when pith is present."1 We of the present are accustomed to this as being the structure of stems. Let none be disquieted by the fact that Theophrastus does not limit bark, wood, and pith to stems; for we are learning that he never writes a line carelessly; never indites the simplest and most fundamental proposition without rigid investigation and profound forethought. Possibly we shall find that he thinks the substances of bark, of wood, and of pith all 1 Hist., Book i, ch. 3. 98 SMITHSONIAN' MISCELLANEOUS COLLECTIONS VOL. 54 occur in other parts besides stem and branches — in leaves, or even in fruits. Now if the history of plant anatomy is to begin as near its true beginning is possible, those three Greek terms must be con- sulted which come into our language as bark, wood, and pith. The first two will not detain us. The bark and wood are, each in many different ways, too indispensably necessary to primal man, to have failed to be distinguished and named long before the advent of the most primitive philosophies. Theophrastus took the terms cp\oiog and £v\ov as he found them, ready to hand and well suited to his use. It was otherwise with the term which he selected by which to indicate the pith of plants. This part was not well known. Primal man, in quest of only the obvious and the useful in nature, may have been unaware of the existence of it. Woody growths, in that mature condition in which they supply the savage and the half-civilized with timber, fuel, bast, and dye-stuffs, show no pith. But that enlightened and philosophic inquiry into nature's obscure things, which Greeks had begun to pursue before Theophrastus' time, had brought to notice this part of plants which was not bark, neither wood. The philosophic must have discussed the substance, perhaps had written about it, for they had attempted to name it. This we have from Theophrastus himself, who says that some called it the heart of plants, others called it the marrow.1 In this connection he did what with him is most unusual, almost timorously conservative man that he was; he declined to accept either "heart" or "marrow" as a suitable name for this part of a plant. This can mean nothing else but that he himself had taken the pith under special in- vestigation and thereby had reached a new conclusion ; had found that it was in no important point analogous to marrow, and farther still from corresponding to the heart in animals. AVe know enough about Theophrastus' temperament to warrant the assertion that he would have been the last of men to reject two names already in use for a thing, until he was able to prove that both were utterly false to nature. The new name which even- tually he offered is one which can not have suggested itself from any study of the substance in that dry, whitened, imponderous, and effete condition in which it is seen in mature stems and branches, in which condition alone we of to-day call it pith. As philosopher, and as one whom we, if he had lived in our time, should have ' Hist., Book i, ch. 4. LANDMARKS OF BOTANICAL HISTORY GREENE 99 known as a "scientific botanist," what he wished to ascertain was the function of this substance in the economy of plant life. This he certainly did discover; but he never could have done so had he confined his investigations to the pith as no longer vitalized and operative; therefore he must have sought it in its young and growing state, when of all parts of the plant this is most tender, replete with sap, and a strong center of vital activity, really the matrix within which are generated both bark and wood. The new name which he gives it is [.u'/Tpat, the word mother, nt'/typ, somewhat altered, and in earlier Greek the womb, the mother of life.1 Theophrastus never records his processes of investigation; but when he selects the word metra, matrix, to be the appropriate name of the pith of plants, we see at once that it does not really apply to it in its white, imponderous, and devitalized condition, and that he must have named it in reference to its earlier state, that of living parenchyma. We may well divest ourselves of the prejudice that the beginnings of a scientific and sound plant anatomy were not made until after the invention of lenses and microscopes. This man of antiquity, he who had progressed so far in plant em- bryology as to have made out even the seed distinctions between •exogens and endogens, could just as easily discover, in the cross- section of a large and very tender shoot of elder or of maple, the first traces of the several fibre-vascular bundles standing in a circle midway between where the pith was to be and the place of the bark. Successive cross-sections made at intervals would reveal to him the gradual hardening and widening of those bundles, their final apparent meeting and coalescing into the cylinder of hard wood intervening between the central pith and the now formative bark. It is undoubted that Theophrastus had thus seen, in young shoots, the early stage at which bark and pith are all one in form and substance, and that from it, even within it, both wood and bark are gradually generated; and that because of this he called the juicy soft living pith the metra, the matrix. In reality, while searching to find what pith would be like in its living state, and what in that state its function might seem to be, Theophrastus had discovered living parenchyma. Such a conclusion, when we have been driven to it in order that the man's words may not be meaningless, needs no further support; and yet there is one other circumstance which would confirm it 1 Just as in certain European languages still spoken there is no one word for womb, but the phrase "mother of life " instead. 1OO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 were confirmation called for. Hitherto I have conformed to usage, very ancient as well as modern, of writing bark, wood, pith, in just that sequence. It seems natural. It is at least a geo- metrical succession of the terms, and therewithal not inelegant. Even the translators of Theophrastus from Greek into Latin have made him out as having named first the bark, then the wood, and lastly the pith. Unwittingly they committed an inaccuracy, and have misrepresented him; for Theophrastus wrote it thus: bark, pith, wood. This sequence is not geometric, but it is biologic. It would be illogical and awkward, were it not more exactly truthful than the other and merely geometric succession of the terms. As he placed them, the story is told again of how in early stages of development bark and pith are substantially identical. Therefore in their most widely differentiated conditipn they are next of kin, more nearly related each to the other than either one is to the wood. This biologic investigation of the pith led to the detection and segregation of other elements in stem structure; discoveries that are all his own, for he expressly says of these elements that they have no names. He thinks that he can not do better than apply to each the name of some analogous part of the anatomy of animals. The whole fabric of stems he makes out as consisting of what he calls veins, nerves, and flesh. They are new uses of these terms and he defines the botanical use of each, premising first of all that vein and nerve are substantially one, differing scarcely otherwise than as to dimensions, nerves being smaller than veins; adding also that in plants these are simply elongated and do not branch. The universal mark of the fabric which is composed of them is, that it splits, and is not otherwise readily divisible. Flesh has the very different quality of being divisible with equal readiness in all directions, like a lump of earth. 1 Here, quite as we had been prepared to expect from his new naming of the pith, and his indi- cating its consanguinity with bark rather than with wood, we see plainly that Theophrastus discovered and distinguished well what in post-Malpighian times we have learned to know as parenchyma and prosenchyma. He is now able to add a new chapter to plant anatomy, for he can name the elemental constituents of bark, of wood, and of pith. Wood, he says, is composed of nerve and moisture; although some woods, such as of the palms and of ferula, are of flesh ; such however in mature and dry condition show that the flesh has been partly converted into wood. When he cites ' Hist., Book i, ch. 4. LANDMARKS OF BOTANICAL HISTORY GREENE IOI the wood of palm and umbellifer, we realize the expression of the popular notion of wood as being that which the bark of any tree encloses, without regard to density or ponderability. His language here nevertheless evinces plainly his having taken full cognizance of the fundamental difference between the wood of palms and that of all exogenous trees. To pith he attributes flesh and sap only. Bark is composed of all three of these elementals in most cases, as in the oak, poplar, and pear tree, though in some, the grape-vine, for example, of nerve and sap only — that is to say, without flesh, or what we call parenchyma. The structural elements of the leaves of exogens he apprehended as substantially identical with those of the bark. The stalklet, and therewith the fibrous framework of the blade, are of that which he designates as nerve, or sinew.1 Next to this he names the epidermis, and after that, what he callsthe flesh, known to us as the mesophyll. In the leaves of palms and reedy or grassy plants he finds no flesh at all, and thinks these are composed of fibre and epidermis only. The edible fruits of trees and shrubs are composed mostly of flesh, with little or no fibrous tissue; while, on the other hand, some pericarps consist of a rind or skin only. He has so clearly distinguished these two or three elementals of the plant fabric that he is able to trace and point them out in every plant organ from root to fruit. Phytography. In descriptive botany there are two different methods by which it is undertaken to convey by means of language the image, so to speak, of some tree or other growth which the describer has seen, and the reader is supposed not to have seen. That two distinct methods in phytography exist is something of which I have seen no mention either with any botanical author, or with any historian of botany ; but a suggestion of them has been made very recently, with also a good account of Theophrastus' phytographic method, in an excellent treatise on some parts of Theophrastan botany by Dr. Hugo Bretzl. Let me for con- venience designate the methods as the natural and the artificial. They may, however, quite as fitly be named the comparative and the positive methods of plant description. Of the two, one is very ancient, the other strictly modern; and the artificial or positive is doubtless the more perfectly adapted to its purpose, though only for such writers and such readers as are competent to use it; for it requires the mastery, on the part of both, of a very extensive vocabulary of special terms; in reality, the learning of a new 1 Hist., Book i, ch. 17. 102 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 language. What I have designated as the natural method of describing plants vindicates its right to that title by the fact of its primitive universality. If I speak of it otherwise as the method of comparisons, in allusion to what it chiefly exacts of him who would use it: that is, first, familiar acquaintance with certain specific types as standards of comparison, and second, the ability to construct a mental image of the unknown by means of the describer's telling in what several particulars it differs from the given type known to both. By way of illustration, an untaught woodman, familiar with junipers, reports to a botanist that in a new region to which he has wandered there are trees in all respects like red cedar, or juniper, except that instead of yielding berries they bear round cone-like bodies approaching the size and form of smallish walnuts. The botanist at once pictures in his own mind cypress trees, and assures his informant that his new trees are cypresses. Such is the method of comparison in phytography; and it may quite as aptly be called the natural one, for it is that invariably used by the primitive and untaught; not, however, always very well and successfully. Being the primitive method, it is therefore that of Theophrastus ; not, however, to the complete exclusion of a number of absolutely definitive terms such as are now in use and always have been. The Greek observed that, taking the plant world as a whole, the leaf is the most endlessly diversified of organs, and also that within the limits of a species its form is constant; from which two conditions it follows that no other organ is so readily available in making distinctions between different plants. Now as to the art of plant-description by the method of comparison, it is very necessary that the types to be used in comparing be chosen considerately. There seem to be indications of his having thought upon this matter, though he has not explained, or even didactically set forth his scheme. It is only by a certain order and fitness in the scheme itself that one infers the author's having studied it out. The most common types of leaf outline are perhaps the lanceolate, ovate, oblong, and suborbicular. He knows nothing of any such terms; but when he wishes to say that which would express what modern botany expresses by the term lanceolate, he says the leaf is that of the laurel, i. e., Laurus nobilis. A leaf that we should describe as oblong, unless it be much too large, is with him that of the olive tree. A leaf that is of rounded contour and nearly as broad as long is compared by him to that of the pear tree. For the ovate in outline his type is the leaf of the ivy, Hedera Helix, in respect to which one must LANDMARKS OF BOTANICAL HISTORY GREENE 103 not fail to note that it is the leaf peculiar to the mature and fruiting ivy bush, not that of the rooting and climbing young plant; for the leaves of this are too broad to represent the ovate, and are angularly lobed. Note now certain points of agreement among these four leaf- outline types, (i) All are leaves of trees; for few herbaceous plants display such uniformity of foliage as to the individual speci- men. There is apt to be one form and size of leaf near the base of such a stem, and another widely different description of leaf at the summit, with intermediate forms up and down between base and summit. With some notable exceptions — of which the Greek takes advantage here and there — leaves of herbs do not answer the purpose. (2) The trees are all selected from among such as are most universally and familiarly known; every one of them common in cultivation. Every civilized Greek of three thousand years since knew the sweet bay. the olive, the pear tree, the ivy. (3) The leaves of them all have a certain firmness of texture, either leathery, or approaching it. By this prevision any soft herbaceous plant having lanceolate entire foliage may be described as to its foliage by merely saying that its leaves are like those of the laurel, but thin. (4) The leaves of all four of the types are entire : whereby the leaf that is of lanceolate cut, coriaceous texture, and entire margin, no matter in what genus it may occur, may be described by simply saying that it is the leaf of the laurel. Supposing, however, that a tree is to be described the leaves of which are lanceolate, coriaceous, but with margin serrated, then its descrip- tion as to leaf will be, that it is like the laurel leaf, but •Serrated. And this selecting of types that have entire leaves is manifestly better than it would have been to have selected serrate leaves for types. In such a climate as that of the Mediterranean, evergreen trees and shrubs predominate, all of them with coriaceous foliagei the kinds with entire leaves being very notably in excess of those having toothed or serrated leaf-margins; therefore the choosing of as many entire-leaved types as he could was natural to a man in Theo- phrastus' place and environment, as well as making for economy of time and space in describing things. It was by no means acci- dental that this descriptive botanist selected the olive, the sweet bay, the myrtle tree, and the box as patterns of leaf outline to be referred to in his phytographic work. 1 How well such a system of morphologic types is adapted to the 1 See also Dr. Hugo Bretzl, Botanische Forschungen des Alexander zuges, pp. 8-22. 104 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 purposes of description may best be shown by quoting a few examples. A wild elm tree that inhabits the mountain districts he says has "leaves like those of the pear tree, but longer in pro- portion, with serrated margin, and a rough rather than smooth surface."1 This makes it plain that Theophrastus' first purpose in choosing leaf types was that of imparting ideas of general out- line. To begin the account of an elm leaf by affirming it to be like that of a pear tree is awkward and even mischievous, upon any other supposition than that by such phrase he alludes to size and general circumscription only; which also the expressions im- mediately succeeding prove; for he who had pictured in his mind at first a pear leaf for an elm leaf must now proceed, under direction of the describer, to alter it by giving it a very distinctly saw- toothed margin, and after that a roughness of surface, of which there is no trace upon the pear leaf. What he now sees mentally as a leaf of the little known wild elm is like a pear leaf in nothing save its general contour. The elder tree, Sambucus nigra, Theo- phrastus seems to have taken pleasure in describing rather minutely, although the tree was no rarity, but rather familiarly known. But it seems to have been this which taught him the existence of such a thing as a compound leaf; and he gives a particular account of the species from root to fruit. When he comes to the lanceolate individual leaflet he says it is like the leaf of the sweet bay but larger, relatively wider in the middle and at base, more pointed at summit, serrated all around, and the whole more soft and pliable in texture.2 To one acquainted with the sweet bay and the elder, I do not know where, in even the most recent botany, he will find a, more complete description of the elder leaflet. The leaves of maples, mostly wildwood trees and less familiarly known, are com- pared with those of the omnipresent plane. The maple leaves are also ample, cleft somewhat after the same manner, but not to the middle as in the plane, Platanus orientalis, longer in proportion to their breadth, of a more delicate texture, and not rough to the touch.3 This system of leaf describing by comparison with types is both natural and not ill adapted to the purposes of phytography. Had it not been so it would not have remained in vogue for two thousand years after Theophrastus. Greek authors after him, as well as Pliny and other Latin writers, knew no other method of leaf 1 Hist., Book iii, ch. 13. 2 Ibid., Book i, ch. 13. 3 Ibid., Book iii, ch. n. LANDMARKS OF BOTANICAL HISTORY GREENE 105 diagnosis. The number of the indicative types was gradually augmented, and the use of them was universal even with the fathers of sixteenth- and seventeenth-century botany; nor has any later generation wholly ceased from the usage ; though it is perhaps chiefly conspicuous nowhere but in nomenclature, where such specific appellations as salicifolia, alnifolia, betulijolia, delphini- folia, and a hundred more, though ostensibly figuring but as names, may chance to be the best part of the diagnosis, at least in the estimation of any not well versed in the post-Linnaean descriptive terminology. It is not to be inferred from anything here said, that the Greek knew nothing of any geometric terminology of leaf forms. In that chapter in which he treats of leaf forms in general he names the orbicular, the oblong, the angular, and some others1; but they lack definiteness of meaning, at least such definiteness as the exigencies of plant diagnosis call for; though terms that bear upon differences of apex, margin, and base as well as the superficies of the leaf are of more fixed and certain meaning. It will be observed that even flowers are described by Theo- phrastus comparatively, the less known being brought into con- trast with the well known; and the same rule applies, of course, in his diagnoses of fruits and seeds. He was not particularly given to describing plants. A great proportion of those which he discourses upon were well known to all who would become his readers. The common things of the gardens, of the cultivated fields, of orchard and vineyard and of academic grove, were so familiar that the mention of the name was sufficient. But when he undertakes the description of any herb or bush or tree, he is apt to give more than a rude outline of it; very often a good word picture of it; and he who does this is a master of phytography, without question about the age in which he has lived, or the method he has employed. In the case of a number of Asiatic and African trees unknown to Theophrastus except by report of travellers, he so carefully gleans all that others have said about them, and with such consummate art sums up the whole, and draws up his own description, that in reading it one finds it not easy to realize that the author of it never saw the tree. The books of botany that were composed by Greeks and by Latins within three or four centuries after Theophrastus show that the authors of them copied his descriptions whenever such were available, and in other cases made his the model of their own diagnoses. When we come to the 1 Hist., Book i, ch. 16. 106 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 era of strongly renewed scientific activity in the sixteenth century, we shall find botanical authors of the time employing many of Theophrastus' descriptions of plant species without altera- tion of any kind; some, like Brunfels, Tragus, and Cesalpino and their class, formally crediting each such diagnosis to its ancient author, others without making such acknowledgment. But they of this period who ventured upon new descriptions of plants which Theophrastus had described of old seem to have exposed themselves to public censure, as needlessly, perhaps ir- reverently, supplanting or amending the excellent work of the father of phytography. Taxonomy. To teach, as it has been taught and is still taught, that Tournefort (1694) first ranged the members of the plant world under genera, that Linnaeus (1753) first clearly distinguished species and varieties, and that Adanson (1763) first proposed the grouping of genera into families — all this is to inculcate fable. It has been already suggested, and forcibly enough, that plant taxonomy was not invented in any school, or by any philosopher; that it is everywhere as old as language ; that no plant name is the name of an individual plant, but is always the name of some group of individuals, and that all grouping is classifying. Botanical taxonomy began at whatever time far off and prehistoric men began to give names to plants; and it increased with the recog- nition and the naming of new groups — always groups, never single plants. Had some earlier Theophrastus appeared upon the scene some thousands of years earlier than this one did, in this particular at least he would have found himself in the midst of a like environment. He would have found some hundreds of kinds of cultivated plants familiarly known, spoken of always under group names. In other phrase, he would have found a certain taxonomy ready to hand, such as answered the needs of those who had to do with plants industrially. The real Theophrastus, entering the field, not in the far-off age of Homer, whose poems are full of tree and plant lore, but many hundred years later, had much to do in the first place in acquaint- ing himself with the vast sum of knowledge, of theory, of poetic fancy, and of superstitious fable that was then extant concerning plants. All this he accomplished, as his pages plainly show, and that with the occasional expression of something like the scientific man's impatience of the superstitious and the fabulous. As distinctively a nature student, however, exploiting the realms of nature from the philosopher's viewpoint rather than from that LANDMARKS OF BOTANICAL HISTORY GREENE of the economist, it would not have been strange had he invented some new taxonomic scheme of his own, and then, thrusting aside all the commonly accepted plant groupings, had sought to install an entirely new system of taxonomy in place of the old.1 He did nothing of the kind; and if he did not, it may have been for the excellent reason that that already in vogue, when duly examined, to a great degree commended itself to the philosophic judgment as having been deduced from nature, and that in as far as it had progressed, was often well enough done. Parts of it could not be amended, and, we may now say confidently, were destined to accept- ance as sound taxonomy as long as the world of plants should endure, or a botanist remain to study it; at many points it might be amended or added to, and the whole must be extended and variously improved. We may assure ourselves by a study of Theophrastus, that something very like this was the task to which he addressed himself as regards the classification of plant organs and the systematization of p ants themselves ; and the careful reader of his chapters will note often his great conservatism — his manifest aversion to startling the good public by pronouncements that are new, and that will openly antagonize them as assailing their old doctrines and their deeply ingrained prejudices. All these things being true, one ascertains with difficulty, if at all, what the historian is most in need of knowing, namely where this writer of the first book of botany is recording points of tax- onomy that are of prehistoric discovery and universal traditional acceptance, and where he is introducing some amendment or improvement of his own. For example, in a very early chapter of his work Theophrastus ranged all the plants that he had ever seen, or heard, or read about, under the four primary groups of tree, shrub, half-shrub, and herb — Sivdpov, Octavos, (ppvyavov, Ttoa.2 It is one of the most classic pieces of plant taxonomy; one that stood the test of all the ages and is immortal. Nothing that by any means could be elicited from out the hazy past would be of deeper botanical interest than information as to whether this fine piece of taxonomic work had been handed down in its com- pleteness to Theophrastus, or whether as he gives it it represents much augmentation, or condensation, or finishing and perfecting accomplished for it by himself. We have met with like pro- 1 This is almost precisely what Tournefort undertook to do in the seven- teenth century, and Linnaeus again in the eighteenth. 2 Hist., Book i, ch. 5. 108 SMITHSONIAN MISCELLANEOUS COLLECTION VOL. 54 blems before1 ; to the full solution of this I am incompetent. For this, the botanist's best skill would need to be supplemented by the erudition of the specialist in Greek philology. Nevertheless the following hints may make it plain that SevSpov, Qd^vog, tppvya- vov, noa, is a piece of classification that was studiously wrought out by Theophrastus himself. In the Greek of his time there were at least two words for tree, devdpov, and vX?], the former more particularly designating such as were cultivated; the fruit- bearing, nut-bearing, and such as were planted for shade or orna- ment; the latter applying more specifically to wild trees used as timber; almost the equivalent of our English terms woodland, forest, timber-tree, etc. We have elsewhere remarked upon the Theophrastan classifying of all growths as tame and wild. The idea was deeply seated in the Greek mind; and for trees in general, wild as well as domesticated, he could not well have chosen any other term than dsvdpov, though it was more properly the appellation of the civilized, contingent of arboreal growths. Similarly da^vos, at least etymologically, signified a densely compacted woody growth, — and not necessarily of low stature. The full-grown olive tree was sometimes called a Qd^vo^, on account of the bushy density of its head. Also as looking to the distinction between bushes of cultivation and a wildwood thicket, the latter was also v\ri sometimes, if not even usually. Thus again as with dtvdpov the botanist selects for extended use that which signifies the cul- tivated and better known. Coming now to the class of suffrutescent plants — the half- shrubby, half-herbaceous kinds — it appears to me no less than certain that Theophrastus was first to discover, indicate, and name this particular category. There seems to have been no word for this kind of thing in the older Greek; for (ppvyavov meant nothing more than a bundle of faggots, dead and dry branchlets and twigs of trees which, either as windfalls or as left behind by the wood- chopper, were laid lengthwise and tied into bundles for fuel. There was, however, the old word 6 d prior, which one almost wonders he did not adopt for his category of the half-shrubby. It is but a diminutive of 6 a pros and means a little bush or small shrub. At second thought one perceives that it would not well answer the purpose. It gives no intimation of the true characteristic of the suffrutescent growths, which is this, that the lower and woody part represents a shrub, while the upper portion, that which bears more scattered foliage together with the flowers and fruits, is 1 See page 66 preceding. LANDMARKS OF BOTANICAL HISTORY — GREENE 109 herbaceous — that is, dies back every autumn after the fruiting and is renewed again in the summer. In late autumn and early winter, while the dead or half- dead upright and parallel summer branches are still present, surmounting the shorter tuft of truly woody lower branches, the bush would vividly enough recall a faggot bundle. Even where abounding, as such growths do on open plain or stony mountain slope throughout all half-arid regions of the world, they must have been used as faggots always. He who knows familiarly such ancient garden plants as the lavender and sage and rue, and the wild half-shrubby artemisias and other like composites of all dry climates, will perceive readily that (ppvyavov, the faggot bundle, lent itself to Theophrastus' scientific purpose in this instance. He might have created a new term; but the con- servative prefers to make new use and application of some old and familiar term. The public never takes kindly to new names. In distinguishing the category of the suffrutescent, the Greek had proceeded analytically. In establishing upon all herbaceous plants one comprehensive group under one name, his procedure was synthetic. It was not indicating a single new group hitherto unrecognized and naming it. It was the synthesis of a number of groups long recognized and separately named ; the putting together of such, to constitute a single more comprehensive assem- blage, and under one name. A glance at the actual situation in which we English-speaking people find ourselves as to our terminology of the herbaceous will help us to apprehend clearly the Theophrastan standpoint. We have no single word by which we venture commonly to designate the aggregate of things herbaceous. If in our fundamentals of botany we still follow Theophrastus in writing or speaking of tree, shrub, and herb, that is at once the beginning and the end of our using the term "herb" thus comprehensively. Thenceforward we ignore it and write or speak about "herbaceous plants"; this for the manifest reason that "herb" used by itself has almost universally a special meaning of which it seems impossible to divest it. An herb is some- thing, neither tree nor shrub, which is either medicinal, aromatic, or culinary. The other terms in common use for subordinate groups of herbaceous plants are vegetable, weed, grass, and worst of all the word "plant" itself; for this, as first introduced into our English speech, and as almost universally employed down to our day, signifies only things herbaceous, yet not all; for neither weeds nor grasses are commonly called plants, in our tongue, except technically. Thus our category of the herbaceous includes the IIO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 segregates herb, vegetable, weed, grass, plant. And the endeavors of our English scientific forefathers to make any one of those terms serve as the name for herbaceous growths in general have been unsuccessful. Theophrastus had been in the same pre- dicament as that which became theirs. In his mother tongue there was g)vrovt the herbaceous plant of cultivation, at least as to its most primitive signification; there were haxavov, the kitchen-garden vegetable, fiordi'i], the weed, and noa, the grass, the forage herb. The first of these terms tyvrov, the herbaceous thing that men plant and transplant and cultivate, was a term that he himself appears to have rendered unavailable. He had made it to include the whole vegetable kingdom from oak and pine to seaweed and fungus. The name that to him seemed most reasonably available for designating the sum of all things green — herbaceous — was the common name of the grasses and fodder plants, noa. When I say reasonably available, my thought is that the selecting of the term grass rather than the term herb for expressing the aggregate was most natural to any one who, like Theophrastus, had thought the matter over. The grasses form by far the greater proportion of that low-growing verdure which, outside of the forests and thickets, covers the whole earth in all temperate lati- tudes during half the year. It was therefore more true to nature — more scientific — to take up that term which came so near being synonymous with verdure. The term herb is comparatively unfit, as suggesting a much smaller aggregate, and that also of plants marked by odors, flavors, and other qualities which the eye can not detect. There are even modern languages in which the word for all green herbage is the correlative of our word ' ' grass ' ' : languages in the botanical vernacular of which, what we call herbaceous plants are known only as " grass." This was strictly true of our English of only a few centuries ago.1 Thus again how plain it is that the forefather of all botany produced this primal outline taxonomic only after the most careful weighing and considering of every point involved. Nor must our attention be called away from this first chapter of Theophrastus' classification without our having observed the sequence of the groups. Why does he begin with the Grand Division of the trees and proceed downward to that which 1 There is a familiar sacred verse that attests this: "All flesh is grass, and all the glory of man is as the flower of grass. The grass withereth, and the flower thereof falleth away. " — I Pet. i, 24. At the date of this translation gramineous plants were regarded as flowerless. Therefore in the minds of tfte learned translators even showily flowering herbaceous plants were a part of "grass. " LANDMARKS OF BOTANICAL HISTORY GREENE III will include such phytologic ambiguities — for such they were in his day and for ages afterward — as lichens and fungi? There is no room for doubt that one consideration was the very rational one, that botany may not safely begin at any point where doubt may arise as to what realm of nature the subjects of study belong to. The title of trees in general to be regarded a part of the plant world is secure; that of no other growths more so; while judged by his own criteria of phytologic rank, the very highest place must be accorded to trees. In his view they were the most perfectly organized of all. Inasmuch as the fourth and last Grand Division noa, the Grass Plants, i. e., the Herbaceous, is the largest of all as to numbers both of individuals and of species and as regards their almost universal prevalence, it will naturally be here that we shall look for further expression of taxonomic idea; suggestions of grouping subordinate to that of noa, the herb. The most comprehensive of his subordinate groups is that which he denominates Haha^GoSi]?^ which comes into Latin as Arundinaceae; its type being that superb grass Arundo Donax. In an author so primitive one does not look for any rigidly formal diagnosis of a group. Calamodes in itself is diagnostic. It will include all plants that recall calamus, that is, Arundo Donax. In one place he has written that the leaves of this, and other things which he cites, seem to be made up of nerves only, comparing them with those of the grape and fig, which he says have not only nerves but also flesh and epidermis in their make-up.2 The interpretation of this is that he has become aware of the differences of anatomical structure subsisting between the leaves of endogens and exogens. His group Calamodes — better written, after the usage of his Latin translators, Arundinaceae — embraces Arundo and the cereals Triticum, Secale, Hordeum, Oryza, and others; that is, he names these as types. By their leaf characters all other gramineous plants cultivated and wild, known or unknown, fall within the lines circumscribing his Arundinaceae. And what else besides the true grasses? In one place he names as among the arundinaceous certain plants the leaves of which in so far depart from the typical as to present an angular cross-section, and these seem to him as if made up of two leaves joined by their edges to something like a keel. It is the conduplicate and keeled leaves of such things as Cyperus and Sparganintn, as any botanist would know from the 1 Histt, Book i, ch. 10. 2 Ibid., ch. 17. 112 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 description of them, even without Theophrastus' having named those particular genera, adding that other denizens of marshy grounds have such foliage. Even the palms — of which he knew only Phcenix, pinnate-fronded — he cites by name as being arundi- naceous.1 Such reeds and rushes as to him seemed quite leafless would still vindicate to themselves places within the group by virtue of their altogether pithy or else hollow stems or culms. We are sure, then, that this assemblage of the Calamodes embraced all true grasses, all sedges, besides the juncaceous, typhaceous, spargan- iacous, plants, and palms. It will be observed that all are mono- cotyledonous ; that the group embraces by far the greater proportion of such; only the showily spathaceous and the really petaliferous genera being left out. Recalling here the circumstance that in all early taxonomy roots figure very conspicuously, it becomes inter- estingly significant that into this great class of the Calamodes, — a group which, as regards the number of species, comes near being the equivalent of our endogens — not a genus is admitted that has either bulb or corm. Every member of the vast assem- blage has copious fibrous roots ; these in moiety of the species sup- plemented, as Theophrastus might have worded it, by that which he had chosen to name the jointed root, i. e., the slender rhizome; a single sedge, Cyperus esculentus, bearing nut-like protuberances as if at the ends of some few of the root fibres. There is not the shadow of a doubt that this pristine plant anatomist and systematist recognized the structure of leaf-stalk and flower-stalk of Arum and Colocasia as at full agreement with that of half his Calamodes; and the same must have been familiar to him in the case of the grassy-leaved crocus and its allies; and the "roots" of these must have excluded them from taxonomic consociation with the rest, in all probability, even had their flowers been leafless and less in contrast to those of grass and reed and sedge. The aggre- gate of bulbous and cormose plants, the araceous I think excepted, were known and spoken of by him as poXficodijs — the Bulbaceae. As a group it contained, first of all and typically, the onion and its several congeners, even the leek, a plant that though alliaceous is not bulbous ; after these the bulbous Liliaceae, Amaryllidaceae, and the cormose iris allies. With the types and several of the species of all these he was familiarly acquainted. There are other natural families not a few of which Theophrastus apprehended with precision, even assigning names to several of them. Such are the Umbelliferae, for an example, to which as a i Hist., Book i, ch. 16. LANDMARKS OF BOTANICAL HISTORY GREENE 113 family he gives the name vapQrfxoadrjs, which in the Latin versions had to be written Ferulacsae, from ferula — in Greek vaptft/S, a stalk of fennel or of ferula — commonest umbellifers of the Mediter- ranean region. Plainly the thistles and their natural allies were accepted by him as constituting another such family group; for he often refers to them under the collective name of acHavOcoSijz, and twice mentions that all of them are prickly-leaved herbs whose flower consists of a head of florets, each floret sitting on the summit of a seed.1 In Latin versions these are the Acanaceae, fromCmcws Acarna, Linn., one of the most common thistles of Greece and Italy. Into this family Theophrastus admitted Dipsacus, the leaves of which are not prickly, as he concedes, but on account of its answering to the thistles in this, that its florets crown each its seed. And Eryngium also, and not unnaturally, with its spinescent foliage and capitate inflorescence, finds place among the thistles rather than with the umbellifers. The numerous cichoriaceous genera, with their peculiar habit, milky juice, and sameness of character as to flower and fruit, formed also a family with our Greek, who called it Hix^pioad^,2 which the Latins wrote Cichoraceas. These for examples of his having given to groups of genera class names and family names. Others need not be cited; but it should be mentioned that the family relationship of small groups of genera is in many an instance clearly seen by him when no group name is used. The pines, fir, spruce, and larch are discussed in a place by themselves; the various poplars, to- gether with alder and birch, occupy successively another place, and the same is true elsewhere in the dendrological chapters of the book. The intimate relationship between the poppies and the pond lilies was so clearly perceived by Theophrastus that, while in general he seems to Hke to group things ecologically, the aquatics in chapters apart from mesophytes, he nevertheless proceeds with- out a halt from the papaveraceous plants of the grain fields to their kindred of the lakes and rivers.3 He perceived upon them all, thi marks of one and the same family. It is again very interesting to note here and there a question: raised as to the extent of some family; whether such or such a genus is or is not of the same family with such another, for ex- ample: "Some affirm that cucumbers and squashes are as closely interrelated as radishes and turnips are; others deny it."4 The i Hist., Book i, ch. 22. 3 Ibid., ix, ch. 13. 3 Ibid., vii, ch. u. * ibid., vii, ch. 4. 114 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 passage reveals gardeners and botanists of remote antiquity in debate about the affinities of genera; and the man whose word of authority might or might not have ended the debate, diplomat that he is, as well as philosopher, expresses no opinion ; though none who have studied him well can doubt that he had one, and the correct one. This outlining of families of plants and giving them family names entails one extremely important logical sequence, which one must not fail to indicate. His Arundinaceae, Bulbaceae, Ferula- ceae, Acanaceae, Cichoriaceae, and all the rest, as established on certain organologic characters, are each and all logically and com- pletely subversive of that distinction which he formally keeps up, between things cultivated and things wild; for each such family necessarily includes both. The few historians who have not shrunk away from the time-consuming task of studying the Theophrastan volumes, have been perplexed by his seeming approval of ancient Hippon's theory about the origin of cultivated plants, which seeming approval is at once followed by a feeble argument or two against the theory. Here is what Meyer says, referring to the primary divisions of tree, shrub, half-shrub, and herb: "Each of these four is subdivided into the groups of the Cultivated and the Wild. Hippon's pronouncement, that every plant is at first wild, and then by cultivation made tame, is thus in a general way ap- proved, though Theophrastus immediately adds that certain wild plants are not at all amenable to cultivation, while others take to it readily, whence it will follow that such a. distinction is not altogether untrue to nature."1 This historian's difficulty arises through his having missed two items important to the understanding of the man Theophrastus. First, that the illus- trious Greek was as successfully a student of human nature2 as he •was an investigator of the plant world; and that he studied to avoid opposing with needless directness the prejudices of the multitude. If he should pay no respect to those time-honored categories of the tame and the wild, but should jumble them all together, and openly, forty-nine out of fifty among his readers would adjudge him not only a bold innovator, but perhaps also a godless heretic; for, as elsewhere intimated, the staple plants of agriculture, even in ancient paganism, were viewed as special •creations of the gods — their immediate gifts to men. Old Hippon 1 Meyer, Geschichte der Botanik, vol. i, p. 162. 2 See his Characters of Men, a work completed, as he tells us, in his ninety- ninth year. LANDMARKS OF BOTANICAL HISTORY — GREENE 115 the rhizotomos had been an outspoken heretic of this stamp. Theophrastus quotes his bold theory. In his secret soul he believes it sound; yet for the sake of avoiding scandal to the forty and nine or the ninety and nine, he veils his belief by admitting that some wild plants refuse to be tamed ; a fact which may innocently be construed as against Hippon's idea. The other fact which the historian failed to apprehend is that the Greek outlines, and gives names to, a half-dozen or more of large natural groups, every one of them embracing without discrimination plants domesticated and wild. He thus completely nullifies that distinction, yet it is all so quietly, and as regards the superficial reading so covertly, done as to escape the notice of the forty-nine out of fifty of his readers; even also of our latter-day botanical historians, learned men and able, yet with mental vision impaired by the strong light of those typographic pedantries — convenient and helpful, certainly — which the botany of the nineteenth century had as a legacy from that of the eighteenth; affected by a sort of botanico-literary dysopsia which is slow to perceive that such a name as ferulaceae is as per- fectly the name fof a natural family of plants as when printed FERULACE^. The recognition of genera — using the term in a modern sense — • is as informal with Theophrastus as that of families. However, when we come to the word itself, yevos, genus, it is employed variously — that is, with several different degrees of comprehensive- ness. Indeed every natural group is with him a " genus," whether it be of the whole assemblage of herbaceous growths, or a family group, or a genus in our sense, or a species, or a variety merely. It seems to be the exact equivalent of our English expression " a kind " ; and because such use of the word " kind " is not yet obsolete, at least surviving in rural districts, it will not be difficult to make plain its meaning. If a gardener or farmer of the present day mention to a botanist that he has in cultivation a strange plant of the squash, cucumber, and gourd kind, the latter understands perfectly that this is something belonging to the family of the Cucurbitaceae, though he can go no further. But if it now be said in rustic phrase that the plant is something in between the squash kind and the gourd kind, he has used the word in a different and much more limited sense; for now the skilled botanist at once puts out of mind seven out of the eight primary divisions — subfamilies — of the cucurbits, or, in other words, dismisses from his thought, we will say, sixty or more of the seventy genera of this family ; for he clearly understands the farmer to have that in view which must Il6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 lie close to the two nearly related genera Cucurbita and Lagenaria. Now for a third manner of using the word "kind," with a most dis- tinct third meaning, the farmer shall say that he has a new kind of squash. The botanist now has not the least doubt that the genus Cucurbita is meant ; whether a species or a variety he can not tell; but the expression "kind of squash" at once translates itself into the school-taught expression, " species or variety of Cucurbita." These three distinct old-fashioned uses of the word "kind" illustrate well the different ways in which ancient Greeks and Latins employed their word "genus." It is not a usage that makes for that perspicuity which a science calls for. For three meanings, three words are better than one. Nevertheless there is seldom room for doubt in Theophrastus' writings as to whether by " genus " he means such a group of species as we receive under that name, or a more comprehensive, or a less comprehensive group; any more than one well read in English fails to get the meaning of each of the uses I have brought forward of the equivalent word "kind." But the modern botanist who innocently should read into the term genus of an ancient author always the meaning which it has in modern botany would soon reduce his own mind to a state of utter bewilderment as to the ancient author's meaning. I have therefore been at the pains of making this attempt at an explana- tion. Upon this and many another important matter of termin- ology the historians have been silent. Employing now the word ' ' genus " quite as used in modern botany the genera of Theophrastus are numerous; most of them obtaining acceptance and holding their places in the systematic botany of the present, most of them also bearing the same names under which they were written about by him. This will be best shown by a few examples, which I select from under the letters A and C of any Latin index to his work: Abrotonum Calamagrostis Acanthus Calamintha Aconitum Cedrus ^gilops Celastrus Agrostis Cenchrus Aira Cerasus Alopecurus Ceratonia Althaea Cercis Anchusa Chelidonium Anemone Cissus LANDMARKS OF BOTANICAL HISTORY GREENE I 17 Anethum Colutea Anthericum Coriandrum Antirrhinum Coronopus Aparine Crataegus Aristolochia Cycas Arum Cydonia Asparagus Cyperus There must be more than a hundred Theophrastan genera the names of which are as familiar as these. A very considerable proportion of them were then known only as consisting of a single species, and are therefore of the kind which we speak of as mono- typical; others wrere made up of from two to several, and the species are mentioned by name at least, when not described. If he establishes no new genus, and all of them which he enumerates or describes were of common recognition, and under those same names, even before he had penned a line on botany, this fact of itself will demonstrate anew the truthfulness of the proposition that the perception of genera and the naming of them are older than history, and that plant names, generic and specific, are a part of human language always and everywhere. As to the grouping of his genera, almost the whole story has been told, at least by implication. There were the genera of trees, the genera of shrubs, etc., in places apart; and there were ecological groupings of wild plants and particular assemblages of genera of things cultivated in field and garden; as to these last, the mere retention of antiquated popular groupings which, in deference to the cultivators, he was unwilling to ignore or displace. There occur in Theophrastus a number of passages which seem like forecastings of a system based more particularly upon flowers and fruits; a system the development of which was of course im- possible then, or even at any later period preceding the invention of the microscope. But the very impossibility of his having been able to develop such a system is something which makes his few and faint adumbrations of it interesting and remarkable. I shall cite but two or three. Commenting on the cylindric spicate inflorescences of certain cereals and grasses, he recalls that those of the plantains are so like them and even the flowers so similar, and thinks it might not be presumptuous to regard them as being interrelated.1 To the average botanist of to-day the idea of any consanguinity as sub- 1 Hist., Book vii, ch. 10. Il8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 sisting between Plantago major and an Alopecurus or a Phleum will seem crude enough; and this partly because parallel- veined leaves do not indicate to a certainty that a plant is an endogen and therefore more or less allied to grasses, and partly because we with our hand lenses and microscopes perceive between the small apetalous flowers of Plantago and Alopecurus marked differences that were impossible of discovery by Theophrastus. But the one thing noteworthy is that the Greek thus makes flower and inflor- escence the criterion of natural relationship. He does not positively affirm it. It was but a pointed suggestion; and the suggestion passed unheeded during seventeen centuries. The true hellebore and the veratrum are not more closely allied than are alopecurus and plantago, but as to their flowers and more particularly as to their follicular fruits, there is a strong likeness between them. It may have been this circumstance which, along with their powerful medicinal qualities, led to their being named as of the same genus, Helleborus.1 More signally indicative of his regard for fruit characters as sometimes taxonomically outweighing the vegetative, is the fact of his having associated the yellow water lily with the poppies, rather than with nelumbo. Having given account of the wild poppies of the grain fields and stony uncultivated lands, he who is so apt to treat of plants in ecologic groups proceeds now to speak of the poppy "that is called nymphaea."2 Evidently its milky juice, the generalities of its floral structure, and above all the external form and the inner structure of the capsule, as well as the seeds themselves, constrained him to think of this and the poppies as congeneric. Also when this same chapter ends with an account of Aristolochia, the capsules of which are so much like those of poppies, one can assign no other reason for it than that by their fruits he guessed that Papaver and Aristolochia were interrelated. Other like instances need not be cited; though it should not here be lost sight of that his families, the Umbelliferse and the Carduacese, were in his mind characterized each by marks of flower and fruit. And so, when the antho-carpologic doctrine of affinities is traced to its beginning, one no longer may think of it as having originated with Cesalpino. The idea had been suggested to his mind, and most impressively, by Theophrastus. Nomenclature. No such thought as that of botanical nomen- clature finds expression with the Greek. When he wrote of any 1 Hist., Book ix, ch. n. 2 Ibid., ch. 13. LANDMARKS OF BOTANICAL HISTORY — GREENE lip tree or shrub or herb he used that name by which it was known in the everyday speech of Greeks. It does not appear that it ever occurred to him that a living thing, or any group of living things, required to be named otherwise than as commonly designated in his mother tongue. When in reading his books one encounters batrachium, erigeron, lithospermum, leucoium, myriophyllum, myrrhis, narcissus, and a hundred more as familiar, it is because he knew no other names for them. Nevertheless Theophrastus has great part in what is now come to be received as the scientific nomenclature of the genera and species of plants; and if this has come to pass without forethought or purpose on his own part, it is still natural and was inevitable. During some two centuries next succeeding the writing of it, this was almost the only treatise on botany that was extant, and the names of plants therein written about obtained by that very fact great prestige. When at length the Latins began to study plants, and would write about them, they had to learn Greek in order to be able to read the works of Theophrastus, for that was the one supreme treatise on plants. All well-known plants were therefore known to Latins by their Theophrastan and Greek names, as well as by their Latin names when they had such. Pliny, the supreme Latin writer about plants, in translating Theophrastan texts by the hundred into Latin for Roman readers, made use of familiar Latin names in place of the Greek names when there were such, e. g., instead of the Greek itea he wrote salix; in place of drys, quercus; Latin ulmus, sambucus, and ranunculus in place of Theophrastan ptelea, acte, and batrachium. There were still many scores of plant types which were known to Latins by no other names than those that had been assigned them in Greek; another evidence that Theo- phrastus by his books had been the one teacher and authority upon botany to Latins as well as Greeks. Platanus, cerasus, rhamnus, anemone, thalictrum, delphinium, helleborus, paeonia, and a host of other such remained the only names of the genera, whether one spoke or wrote botany in Latin or in Greek; and so during some seventeen centuries most of the plant names in use were quoted from Theophrastus. The popular fable about Linnaeus as first nomenclator of botany is not yet a hundred years old, and will need to be perpetuated for sixteen centuries yet to come if the years of his nomenclatorial fame are to equal those during which Theophrastus held the prestige. Early in the sixteenth century, when new impulses moved men everywhere to scientific research, Latin had now long been the I2O SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 universal language of the educated. Theophrastus had been translated into Latin for the convenience of those who had not learned Greek; but still, as to botanical nomenclature Greek held its prestige fully. When in the course of their herborizings the botanists found plants in no wise answering to any descriptions in the ancient books, and therefore adjudged new and nameless, under the conditions then prevailing it would have been the most natural thing in the world if all new plant names of the period had been made in Latin ; and this indeed often happened, e. g., Pulicaria and Fragaria, Brunfels (1531), Digitalis, Fuchs (1542), Sanicula, Tragus (1552), Bidens, Cesalpino (1593): yet Latin names for new genera are somewhat exceptional even for that period, Greek- made names being commonly preferred. The reason was simply this. The greater proportion of plant names then in use, even in Latin botany, was Greek, and that by unbroken tradition from the Greek father of all botany; and Greek-made names for new types were more in harmony with the general tone "of botanical nomenclature than Latin names. Thus has it come to pass that even down to our twentieth century the favorite etymology for new generic names is Greek. Such very modern names as Cal- liandra, Chimonanthus, Ckionanthus, Ckionophila, Chionogenes, Epigcea, and hundreds like them, all very modern, attest the perpetual influence of Theophrastus upon botanical nomenclature. In botany as elsewhere the genus presupposes species. A genus may consist of many species, of few, or of one only. Theophrastus had very many monotypic genera, at least as they were then known. The specific representative of a monotypic genus has with him but one name, commonly a one-worded name; that is, the one species constituting such genus lacks a specific name. It really has no need of any. Where there is but one thing of a kind, there is never in ordinary speech a second and qualifying name. If neither men nor things existed but in monotypes, language would not need adjectives, and there would be none. Had there been but one race of men on the earth, the name of that race would have been man simply, and the adjectives Caucasian, Mongolian, African, etc., would not have existed. The Theophrastan nomenclature of plants is as simply natural as can be imagined. Not only are monotypic genera called by a single name; where the species are known to be several, the type species of the genus — that is, that which is most historic — is without a specific name, at least very commonly, and only the others have each its specific adjective superadded to the generic appellation. The situation may best LANDMARKS OF BOTANICAL HISTORY — GREENE 121 be shown by examples. In giving these it seems advisable to present the Theophrastan Greek names in Roman type. Theophrastan Modern Clethra Alnus oblongata. Melampyron Melampyrum arvense. Dolichos Phaseolus vulgaris. Ostrya Ostrya vulgaris. Peuce Pinus picea. Peuce Idaia Pinus maritima. Peuce conophoros Pinus pinea. Peuce paralios Pinus Halepensis. Mespilos Mespilus Cotoneaster. Mespilos anthedon Crataegus tominalis. Oxyacantha. Mespilus Pyracantha. Syce Idaia Mespilus Amelanchier. Aria Crataegus Aria. Cydonion Pyrus Cydonia. Coccymeles Prunus domestica. Spodias Prunus institia. Cerasos Prunus Cerasus. Pados Prunus Padus. Oie Sorbus domestica. The first four names above are those of genera known to Theo- phrastus as consisting each of a single species. It is evident he saw no occasion for any second and qualifying name in any case of that kind. To have given such second names would very certainly have exposed him to the criticism of having abandoned the attitude of the philosopher, the man of literary taste and scientific brevity, and having assumed the role of the pedant. Why do botanists of a recent time invariably append the needless second name to every monotype ? I ask the question but to em- phasize this point in the history of biologic nomenclature. I recall no instances of the assigning of the useless specific adjective to a generic monotype until well toward the time of Linnaeus; and despite the weight of his authority in favor of it, the nineteenth century was on the dawn when there were no longer eminent botanists standing out against the practice. The assigning a species name in these instances is, of course, previsional. The monotypic genus may cease to be such; but even then, according to Theophrastan usage, the generic name alone might stand as that of the original and typical specific member; but that is too pro- 122 SMITHSONIAN" MISCELLANEOUS COLLECTIONS VOL. 54 vincial. Theophrastus' work, in as far as relates to taxonomy and nomenclature, is provincial; not a universal flora, but a somewhat local one. It was not a perfect pattern for the universal. There is also a certain lack of uniformity in a system of nomenclature which fails to provide every species with a distinctively specific name; and it was nothing more than the desirability of uniformity which brought about the modern usage. But, as we shall see, this question was long in controversy, and was settled late. Matters of nomenclature and taxonomy are almost inseparably connected. The name itself is but the expression of a taxonomic idea. Excepting those rare instances in which an individual historic tree has received a proper name, every plant name that ever was, in any language, is the name of a group. Naming is classifying. The Theophrastan names for pomaceous and dru- paceous genera have been above placed in close succession, and opposite them Linnaeus' disposal of the same type. By comparing those several names it is readily seen that the eleven species are distributed to five genera by Linnaeus, whereas by Theophrastus they had represented nine. In what may be called the average twentieth-century classification of them, — as far as the century has proceeded, — the same eleven species are ranged under about eight genera, namely Amelanchier, Cotoneaster, Crataegus, Cydonia, Sorbus, Cerasus, Padus, Prunus. If we of the present are correct, the mean between Theophrastus and Linnaeus is the happy one; and this in any case must be admitted, that every revulsion against the Linnaean taxonomy of these fruit trees is a step in return toward the Theophrastan. The same sort of departing and then returning finds illustration in the naming of water lilies as that was done formerly, and has been done over again of late. Theophrastan Linnaean Recent Nymphaia Nymphaea lutea Nymphaea lutea. Sida1 Nymphasa alba Castalia alba. Lotos Nymphaea Lotus Castalia Lotus. Cyamos2 Nymphaea Nelumbo Nelumbo speciosa. The Greek, it is thus seen, received the four species as representing each a genus. With Linnaeus the genus of them all was one ; while recent systematists have well-nigh completely returned to the Theophrastan view, in all save the names of the genera ; and the 1 Linnaeus, suppressing the white water lily genus, daringly transferred its name to that of a genus of insignificant malvaceous weeds. 2 Sir J. E. Smith, most ardent Linnaean though he was, restored Cyamus instead of Nelumbo, insisting on its right of priority. LANDMARKS OF BOTANICAL HISTORY — GREENE 123 restoration of even these will follow, under the law of priority. The shortcomings of Theophrastan nomenclature as to uni- formity have not all been indicated. There is one other. While something like half his plant species have but a single one-worded name and that the generic, there are not a few of his genera that are invested with a double — that is, a two-worded name. It is highly important that this be fully understood. This kind of name is frequent with every botanical author that I am acquainted with, between Theophrastus and Linnaeus; and with this fact overlooked there is no understanding any single pre-Linnsean author's plant names either generic or specific. Nor have I found any writer of botanical history making so much as a passing reference to this. I subjoin a very few such Theophrastan genus names as samples; giving, as usual, their equivalents, with also the specific names as now in use. Theophrastan Modern. Calamos Euosmos Acorus Calamus. Dios Anthos Agrostemma Flos Jo vis. Dios Balanos Castanea vesca. Carya Persica Juglans regia. Syce Idaia Amelanchier vulgaris. Ampelos Idaia Tamus communis. Most of the names in the left-hand column have exactly the form and structure of ordinary generico-specific binaries, one term being a noun, the other a qualifying adjective. Their respective equivalents placed over against them demonstrate beyond cavil that these particular binaries are not of the usual meaning of such two-fold names, but are purely generic. To take up the first on the list: Theophrastus has a genus Calamos, the great reed-grass arundo its type, phragmites also being included in the genus. It is not imaginable that a botanist of Theophrastus' ripe experience and great attainments should think those large grass-plants and the sweet-flag to be of the same genus. Beyond doubt, however, that name Calamos euosmos did originate in the notion that arundo and acorus are next of kin; for, however unlike they are as to size, foliage, and other particulars, there is a remarkably close similarity in their rootstocks, these being of almost the same size, form, and color in the two. The gatherers of roots and herbs, as we know, looked first of all to the "roots" of things, and these were their first criteria of plant relationships. To these it would be perfectly natural to place the sweet-flag alongside arundo, the true 124 SMITHSONIAN MISCELLANEOUS COLLLECTIONS VOL. 54 by its closely imitative "root," and then on account of the aro- matic properties of that root to call the plant ndXai^iog ivoff^og. It is equally incredible that Theophrastus should have adjudged the service tree which grew on Mount Ida to be a kind of fig tree. The country people who found the sweet fruits in some way sug- gestive of figs must have been the creators of that name GVHIJ 'Idrna. But the author who desires to conciliate the public will use great reserve in the matter of suppressing, altering, or even amending established and familiar names; and Theophrastus left plant nomenclature as he found it. And what reasonable objection could have been raised against such binary generic names? It can hardly have entered his mind that it made any difference whether such name were one-worded or two-worded. Outside the domain of our Latin-worded technicalities it makes not the least difference to any of us to-day how many words go to the making of a generic name. Ivy is a generic name, and as certainly such are Ground Ivy and Poison Ivy. Pine, Ground Pine, and Princes' Pine are names of three genera in no wise interrelated. The same may be said of the five following, Pink, Moss Pink, Squaw Pink, Mullein Pink, and Pink Root. We having no fault to find with such generic names as Star of Bethlehem, Lily of the Valley, Grape Hyacinth, Jerusalem Artichoke, Indian Turnip, American Cowslip, and some scores of others like them. We are a living illustration of Theophrastus in this regard, except that we have two languages for our botany, whereas he had but one. We have two languages in which we use botanical names, with a separate set of rules for each. Into our Latin nomenclature we do not admit any of these two-worded generic names which we use so freely and so readily in our vernacular. In this we differ from a very long and illus- trious line of our own botanical ancestry. It is less than two hundred years since what we know in English as Dogtooth Violet and in Latin as Erythronium was in all Latin botany the genus Dens Canis, Taraxacum was Dens Leonis, Convallaria was Lilium Convallium, Glechoma was Hedera Terrestris, Helianthus Flos Solis, Drosera Ros Solis, Centaurea was Centaurium Majus, % and the little gentianceous genus Erythrasa was Centaurium Minus. By the same token, Chelidonium was the genus Chelidonium Majus and Ficaria was the genus Chelidonium Minus. In a word, Latin botany for more than seventeen centuries admitted two-worded generic names as freely as the simpler kind ; and all after the ex- ample of Theophrastus and the prehistoric nomenclators. This is not the place in which to give the history of the elimina- LANDMARKS OF BOTANICAL HISTORY — GREENE 125 tion of binary generic names from Latin-written botany. But it was imperative to show that such names are common with Theo- phrastus, Dioscorides, Pliny, and thenceforward for well-nigh two thousand years. Without knowledge of this fact the ancient names can not be understood. Without understanding of names as applied during such period, its taxonomy is an enigma, and the setting forth of the history of taxonomy is impossible. To read into that ancient Greek name Aster Atticus, as has been done lately, the character of an ordinary binary plant name of the nine- teenth century, l — to fail to recognize in that a mere two-worded generic name — seems to evince a condition of bewilderment as to1 the whole subject of botanical nomenclature with ancient Greek and later Latin authors. That the term Aster is generic and Atticus specific can not well be believed to have been in the mind of Dioscorides; for the genus was monotypic, and they did not then give specific names to monotypes.2 Nevertheless, in genera of several species generico-specific binaries quite like Aster Atticus as to form were very frequent with Theophrastus; though he applied them to species and to varieties indiscriminately,3 as the subjoined Latin versions of some of his binary names will show: Salix alba Triticum agrigentinum Salix helix Triticum africum Salix nigra Triticum assyricum Papaver rhceas Triticum egyptium Papaver nigrum Triticum siculum. Papaver corniculatum Triticum thracium. Origanum album Olea domestica. Origanum nigrum Olea silvestris. Origanum creticum Phlomis alba. Origanum heracleoticum Phlomis nigra. Ecology. Among forecastings of method with Theophrastus, that of the natural associations of plants in particular places is very definitely presented. That which we have learned to desig- nate as the ecologic he accepts as being a very natural kind of grouping. "All are distinguishable as either terrestrial or aquatic, just as we also primarily distinguish animals; for there are some 1 E. S. Burgess, Memoirs of Torre y Club, vol. x, (1902), pp. 57 et seq. 2 Sixteenth-century botanical scholars knew this well. Cesalpino wrote the name always as one word, Asteratticus, or else Asteracticus. 3 It was the usage of nearly all authors down to and including Tournefort in the year 1 700. A binary name meant either a genus, a species or a variety. 126 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 plants which grow nowhere but in the sea; small ones in our sea (i. e., the Mediterranean), larger ones in the Red Sea. Others affect only marshes or other very wet places. Some can not live in very wet ground, but restrict themselves to dry ground. Certain others are littoral only. A few trees thrive in either moist land or dry; such are the myrtle, alder, and willow. " 1 In another place, having wild trees and the diversity of them under consideration, he affirms that they differ according to the different nature of the localities in which they grow. "There are lands that are over- flowed by water, there are marshes, and there is dry ground ; there are rocky places and smooth pasture lands and harder soils, besides other diversities. There are depressions in the landscape where all is tranquil, and there are elevated and wind-swept exposures; which varied conditions tend to the production of many different things." Hereupon follows a considerable catalogue of trees which in Macedonia he says occur nowhere but in the mountain districts: fir, wild pine, spruce, holly, linden, hornbeam, beech, box, arbutus, juniper, yew, wild fig, alaternus, phillyrea, walnut, chestnut and holly-leaved oak. Then there is given a list of such as are common to mountains and lowlands: tamarix, elm, poplar, willow, cornel, alder, oak (Q. robur), wild pear, wild apple, privet, hop-hornbeam, ash, hawthorn. As to these denizens of both high- land and plain he says that ' ' in general they are of larger dimensions and more comely form on the plains, but of better timber and better fruit in the mountains. To this rule the wild pear and wild apple are exceptions, both being of better timber and better quality of fruit on the lowlands ; for in the mountains the trees are gnarled and thorny. Even as to the peculiarly montane sorts of trees, those inhabiting the lower valleys are both the largest and the most copious; and on the highest summits everything is in its most stunted condition, excepting such as by nature require the cold."3 Reminding ourselves of this, that Theophrastus treats mainly of field and garden plants, giving much less space to the unculti- vated, it becomes particularly noteworthy that in one place eight successive chapters are given up to locating and describing aquatic and other hydrophilous growths ; 4 all of them, of course, wild plants. Without any formality of naming the distinctions, yet in practice 1 Hist.,' Book i, ch. 7. 2 Ibid., iii, ch. 3. 3 Ibid., iii, ch. 4. 4 Ibid., iv, chs. 7-14. LANDMARKS OF BOTANICAL HISTORY — GREENE 127 he distinguishes (i) marine aquatics, (2) marine littoral plants, (3) plants that grow in deep fresh waters, (4) plants of shallow lake shores, (5) those affecting the wet banks of streams and rivers, (6) and those of marshes. His marine herbaceous plants are mostly algae. The submerged trees, resembling in mode of growth and branching oaks, fig-trees, the palm, and the vine, and attributed to the Red Sea, are mostly corals; organisms that were still con- sidered to be plants, denominated lithophytes, until within the last two hundred years. The author, in describing the marine oak, marine fig-tree, etc., is careful to inform his readers that their resemblances to the trees of the land are only those of mode branch- ing; that they are smaller than their terrene analogues and have no leaves. In stagnant fresh waters several cubits deep thrive nelumbo, nymphaea and trapa. Along the shores, in shallow water are reeds, rushes, the papyrus, sparganium, and typha. The banks of running streams suit the poplar, alder, and willow, the roots of which only are laved by the flowing waters. In wet sandy soil not far from streams thrives the cyperus with nut -like edible roots. That ecology should have formed a sort of taxonomic basis for Theophrastus in his treating of wild plants was most natural. Such pronouncedly hydrophilous growths as reeds and rushes, coarse sedges and the largest grasses, phragmites and arundo, besides typha and sparganium — all are at agreement not only ecologically but in many respects also morphologically. They all have upright, smooth, and simple stems, filled with pith when young, some of them hollow when mature, but none ever woody- solidified; their foliage long, narrow, entire, never with any trace of the network of veins. Moreover, every one of the group was what would have been called flowerless, by all save Theophrastus and his students; because they had no flower-leaves. Other aquatics, such as nelumbo and the water-lilies, colocasia and sagittaria, were like the rest structurally except as to foliage, the leaves being large and ample, rounded rather than narrow-elongated, with radiating veins if any, and some of them with large flowers made up of showy leaves. The Greek, I say, might have written such a diagnosis of his aquatics as a group viewed morphologically. That he saw these marks none will doubt who reads his descriptions of the species. In the vegetation of the mountains he again lists the trees that grow on the exposed and sunward slopes, and those that flourish nowhere but upon cold northward declivities, and such as inhabit only the frigid summits. 128 SMITHSOXIAX MISCELLANEOUS COLLECTIONS VOL. 54 Dendrology. Almost an undue proportion of Theophrastus' space is given to the consideration of trees. He appears to have been a great lover of them ; and his knowledge of them is presented with so much system that at least a considerable dendrological paragraph becomes a necessity if one is to convey any adequate notion of his botanical work as a whole. He classifies them (i) as cultivated and wild. This is one of his general divisions of all kinds of plants ; one that has already been sufficiently discussed in another place. Trees are (2) deciduous or evergreen. Their diversity as to tenure of foliage is so thoroughly discussed, and withal so judiciously, that the more than two millenniums that have passed seem to have recorded but few and unimportant additions or amendments to the principles of this chapter as he left it. 1 Ad- hering to his classification of all things as cultivated and wild, he gives two lists of trees that are evergreen; the olive, palm, sweet bay, myrtle, the cypress, and our pine among the domesticated; for the wild, the fir and spruce, wild pine, certain kinds of oak, holly, box, and the arbutus tree. The last, he says, sheds the foliage from its lowest branches, while the head of the tree remains evergreen. This distinction of evergreen and deciduous he regards upon the whole as quite natural and valid, despite reports he has heard, and readily accepts as probably true, that in the warmest climates grape vines and fig trees shed their leaves so tardily as to seem almost evergreen. He has observed that, among perfectly familiar species, some regularly divest themselves of all foliage in earliest autumn, others later, while a few habitually retain it until winter has begun. He can therefore credit those who assert the existence, in other lands, of kinds that do not cast their old leaves until near the time of the development of the new in spring. He has even found out that the most strictly evergreen develop one new set of leaves, and as invariably lose one old set, every year. Upon deciduous trees and shrubs he seems to have kept phenologic records. He relates that certain kinds come into leaf early, others late; also that such as are first in leaf in the spring are not the first to shed their foliage in autumn, and it is equally established, that those latest in leaf do not retain them longer than others. He has likewise learned that trees in a moist climate and soil retain their foliage for the longest period, while deciduous things of a dry soil and poor shed their leaves earliest of all; and finally, that a young tree keeps its foliage until a later date than does an old one. The foliage of evergreens is usually narrower 1 Hist., Book i, ch. 15. LANDMARKS OF BOTANICAL HISTORY — GREENE I2Q than that of deciduous trees, is of a firmer texture, and in a much greater proportion of species is fragrant or aromatic. In respect to their modes of branching, trees are (3) regular or irregular. If at any time before having studied Theophrastus I had been asked who first taught the distinction between the ex- current and deliquescent in the forms of trees, I should have attrib- uted it by guess to some dendrologist of about the middle of the nineteenth century whom I could not name. Therefore nothing that I have come upon in this author of antiquity has more sur- prised me than his lucid setting forth of these two modes of tree dsvelopment. The differences seem to have forced themselves upon his notice while studying the fir tree. At least, he gives fir as the best type of what we call the excrescent; and the oak is his ex- ample of the other mode as to branching. The distinction (4) of flowering and fiowerless in trees did not imply the recognition of such as in modern botany are called cryptogamous. It was but a matter of the author's success or failure to find what he would have allowed to pass for flowers. And the classifying them as (5) fructiferous and sterile is not at all the equivalent of the flower- ing and flowerless division. There is one kind of sterility that is manifestly accidental only ; a consequence of something unfavorable in the environment. The palm is sterile in Greece; yet if trans- planted to Babylon from Greece, it becomes as fruitful as the Babylonian.1 Peach trees are sterile in Egypt. The wild sorbus of Greece, transplanted from its mountain habitat to the fervid low country, though flowering copiously in the new situation, never fruits there. The reason is plain to him. Its nature re- quires the cold climate of the mountains. But when he alludes to the black poplar of the island of Crete as sterile when introduced on the mainland, one may suspect that to have been owing to the possible circumstance of only male trees having been brought over. I do not think Theophrastus ever suspected the fact of dicecism in any plant or tree, however often we may find him speaking of them as male and female. Of this I have more to say in another place. Again individual trees according to their species have (6) certain of their branches fructiferous, certain others always sterile.2 He has observed that some, like the vine and the fig tree yield fruit on no branches but the newest, those of the season; that almond, apple, pear trees, and many more fructify upon no other branches than those that are one year old; 1 Hist., Book ii, ch. 3. 2 Ibid., i, ch. 23. 130 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 some like the carob (Ceratonia Siliqua, Linn.) produce their fruits both upon those of this season and the season before, with also a few at the same time upon old and thick branches. Some kinds are fruitful on none but their topmost branches; others are fruit- less at summit, and only fruitful on lateral branches. Another distinction is that of (7) the location of fruits in respect to foliage. Some trees bear their fruits beneath the leaves; on others it is borne above them; while in some, like the sycamore fig tree (Ficus Sycomorus, Linn.), >it grows down on the naked trunk.1 From our point of view this is a useless distinction ; but not so with Theo- phrastus, who seems to have been unable to attribute to the foliage of trees any more important function than that of a protection to the young and growing fruit or seed. Trees are extensively treated of (8) as to their ecology and geographic distribution. There are trees peculiar to mountain districts, and others confined to lowlands and plains. As of the former habitat he names the fir, wild pine, spruce, holly, box, walnut, chestnut, and many more. A still greater number of different kinds are of the plains only; among them are one of the elms, the ash, maple, alder, willow, poplar. A few kinds are common to mountain and plain.2 Among the montane some, like the wild pine, luxuriate on slopes that look southward, and will hardly grow at all in any other places, while the fir, on the contrary, attains perfection on the cool and shady sides, and if ever seen elsewhere, has an inferior growth and is unlike itself. The tallest and largest firs known occur in a deep valley in Arcadia where they say the sun never shines. He notes it as a general rule that the kinds of tree affecting shady and cool places are tall and straight, their trunks not forking or parting into subsidiary trunk-like branches ; but that arboreal growths of this latter description are those of open and sunny places. Certain trees are wont to grow nowhere but along watercourses ; and certain others belong exclusively to the highest elevations of the mountains near perpetual snow. It is evident that in those coniferous and hardwood trees belong- ing to cold northward slopes of southern mountains Theophrastus sees a sort of fringe, so to speak, of the great almost unknown regions of Europe northward; for what reports have been brought from that direction indicate that there, even the lower lands are clad with forests of fir, pine, oak, chestnut, and others known at the South only on the mountains; and he thinks it may be reasonable 1 Hist., Book i, ch. i. 2 Ibid., iii, ch. 4; also iv, ch. i. LANDMARKS OF BOTANICAL HISTORY — GREENE 131 to infer that the whole North has no other silva than that thus indicated. He has not been able to learn that it has kinds of trees peculiarly its own. 1 Southward, however, across the Mediter- ranean, and away up the Nile, are very different kinds of trees; many that can not be successfully transplanted from that dry and heated climate into regions where the/e are rains and cold weather at the winter season. There, in some localities where it never rains, the palms attain their greatest dimensions and their best quality of fruit; not, however as indicating that they have no need of moisture. On the contrary, wherever a grove of wild palms occurs water is sure to be found at no great distance below the surface of the ground, though it is usually subsaline, a circum- stance which, he says, has taught the cultivators to use a little salt with advantage in growing dates in other than their native soil.2 In Phoenicia and in Syria there are various kinds of palm; because these like other trees differ according to differences of region and climate as well as according to the culture given them. The palms as a group interest him deeply ; they are in many ways so very unlike other trees, in their best known type bearing every thing — leaves, flowers, fruits — in a single terminal tuft, the cau- dex being without a branch. Now, with Aristotle, father of biologic investigation, and with those of his school, there was much and serious inquiry into the question of a soul, and some particular seat of life in plants. The latter was hard to locate; so many are the trees which, as susceptible of propagation by mere cuttings, thereby proclaim it that their seat of life is everywhere, so to speak. But these palms were different. Cut off the leafy and fructiferous summit of the tree and the whole is killed, just as one kills an animal by decapitation.3 He was near thinking that in this kind of tree that one terminal part is the seat of life; but he knows of a smaller palm, native to the islands of Sicily and Crete (Cham&rops humilis), which, if the top be removed, or if even the whole tree be cut down to the ground, renews itself by shoots from the root. He has grown from seed the few kinds of palms available at Athens, knows all about their germination and early stages of development; finds no distinction of bark, wood, and pith in the structure of their trunks;4 recogni7,es in them the only 1 Hist., Book i, ch. 6. 2 Ibid., li, ch. 8. 3 Theophrastus had heard that at Babylon there were palms of some sort the top of which could be made to root and grow again.

(32 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 plants of which he dares to say that they exist in the two sexes, a male that flowers and is fruitless, and a female thit is Powerless but bears fruit 1 ; but a special seat of the vegetal soul, or life, evades him even here. That he admits trees into the alliance of the palms on vegetative characters alone, when the fruits are not in the least date-like, is seen in two instances. One such is so described as to have convinced some authorities that what he had in view must have been the cocoa-nut palm of the farther Indies ; but it is now no longer doubted that it is the Hyphcrne cor- iacea, and not Cocos nucifera. He also knew, and well described the type of the Cycadacese, Cycas circinalis, as a kind of palm. Theophrastus, like an ancient Humboldt, or Grisebach, takes pleasure in making comparisons between certain of those trees of arid northern Africa and certain others of southern Europe with which all his readers are well acquainted. There is the persea, as he calls it (Cordia Myxa, Linn.), which in some ways suggests to him the pear tree, a large and very handsome tree, in its mode of branching, its foliage, flower, and fruit externally resembling the pear; but it is evergreen and ripens fruit at all seasons, the fruit however possessing a nut at its core like that of a prune, etc.2 There are other Egyptian trees so unlike any known to his un- travelled countrymen that he can not contrast them with any familiar kinds ; but the competent botanist of t'o-day will recognize the genera and species of some of them by his descriptions. About Memphis are trees frightfully armed with thorns in every part except the trunk. It; is the arid subtropic region of several gum- bearing acacias and their allies. He attributes to all of them the leguminous fruit, napno? e AAo/Jo,, says the pods are gathered and employed as a substitute for galls in tanning leather, and also used medicinally. One kind he calls white thorn (Acacia Senegal, Willd.). To this he attributes flowers beautiful and fragrant, so that they make garlands of them. Another he denominates black thorn (Acacia Arabica, Linn.). Quantities of gum are gath- ered from this kind. It exudes from the trunk where incisions have been made, or even spontaneously without incision of the bark. In the vicinity of Thebes there are extensive forests of these trees, and that far away from the river, where they are never irrigated. Such pen pictures of foreign dendrologic scenes are not rare in Theophrastus; and they are always so vividly drawn that the reader inevitably thinks of him as writing from the very midst 1 Hist., Book i, ch. 22; also Book ii, ch. 8. 2 Ibid., iv, ch. 2. LANDMARKS OF BOTANICAL HISTORY — GREENE 133 of the things he is describing, whereas it is quite certain he is only compiling from travellers and historians. To this picture of Egyptian dendrology he will add yet another member of this same alliance of trees, and this the most remarkable one. Forbiddingly spinescent or thorny like the others, it has a more delicate foliage, like that of a fern. Whenever a branch of this tree is disturbed by a touch, all the leaves upon it seem very suddenly to wither away and collapse; then after a little time they revive and return to their former condition. This quaint description of what has been called sensitive foliage is probably the oldest extant. The species that was described by Theophrastus is doubtless Mimosa polyacantha. These and as many more kinds of tree and shrub he mentions by name and short description as "peculiar to that region." In succeeding chapters he dwells at some length upon the ligneous growths of the Arabian deserts, where it rains no oftener than once in four or five years, and trees are scarce and all of them spinescent 1 ; and describes the varied and often luxuriant silva of the more distant Indies.2 It is to be remembered here that Theophrastus was contemporary with Alexander the Great, whose expedition to the farther Orient was the first of its kind in all history to in- clude among its officials learned men whose duty it was to write up the geography, climatology, and even the zoology and botany of the regions traversed; an enlightened thought of Alexander's, beyond doubt suggested by his boyhood's illustrious tutor, Aristotle , father of all nature study.3 To the manuscripts brought back by this scientific staff of Alexander, Theophrastus was indebted for all that he knew of the farther Oriental plant ecology and geography; and all that remains of those reports is what the phi- losopher quoted from them. The originals were long since lost. In these chapters of Theophrastus we have the earliest, and very interesting and faithful accounts of the banyan tree (Ficus Ben- galensis, Linn.), citron (Citrus medica, Risso), the cactus-like euphorbia (E. antiquorum, Linn.), the oleander (Nerium Oleander, Linn.), the tamarind (Tamarindus Indica, Linn.), a tree which they reported to possess the singular faculty of folding up closely its pinnated leaflets at nightfall and going to sleep for the night; Book iv, ch. 8. 2 Ibid., ch. 5.

Plantarum is not without its chapters on the diseases of trees, and the influences of the seasons upon them1 ; the proper seasons of the year for felling timber of different kinds2 ; qualities and special uses of wood of different trees3; but space must not here be given to comment on these economic aspects of the subject. A more philosophic interest attaches to questions of longevity in trees. Under the caption of duration (9) he records a number of curious facts, and discusses briefly a question that may arise in reckoning the age of certain trees. He certifies that it is common with orchardists and vine growers of his time to renew, as it were, an old and moribund tree by cutting it down near the ground, and then training up in its place one of the new shoots that are thrown up from the base of the stump. How, he asks, is the duration of the tree upon this spot to be estimated? Do the old and new tree constitute two individuals or only one? If the main trunk be essentially the tree, then the new trunk is that of a new individual; and he adds that the very roots of the original tree perish, event- ually, and that the new one now has none other than its own.4 Yet individual grape vines the continual growing and fruiting of which during two centuries is perfectly authenticated have in this way been renewed by the cultivator's art, several times over within the two centuries. He finds it a prevalent opinion in the rural districts that all wildwood trees are long-lived and all the domesticated of short duration. This the philosopher does not think well grounded. It is true only in a very general way, and with many exceptions. Some kinds of forest trees live very long, others do not ; and the same may be said of the domesticated, though these, upon the whole, have a shorter period. And, universally, those that fruit copiously have a shorter time of life than the unprolific ; also the kinds of wild trees that affect low and wet land are shorter-lived than those occupying dry and barren ground. Even sweet-fruited and aromatic trees live longer than the sour- fruited kinds, he has observed. On the reputed great ages of certain individual trees still living in his day as well as carefully preserved and religiously venerated — such as the olive tree at 1 Hist., Book iv, chs. 16, 17. * Ibid., Book v, ch. i.

LANDMARKS OF BOTANICAL HISTORY — GREENE 135 Athens said to have been planted by Hercules, and the Caphian and the Delphic planes, both believed to have been planted by Agamemnon — he is somewhat incredulous. The traditions as to their origin have come down by some who also wrote fables. It might be well to investigate. He thinks it quite certain that olive trees and planes, as well as many other kinds, live a very long time. Beyond this platitude he will not go; but it is manifest that he is not in sympathy with the mind of the credulous multitude as to the extreme age of this or that individual and historic tree. He was rather skeptical on the subject, and probably would not have believed it possible that northward in Europe far beyond the Mediterranean oaks sometimes lived through ten or a dozen cen- turies ; nor that on another and unknown side of the world there were conifers1 of considerable dimensions then living which would be flour- ishing still, after the passing of twenty-two or three hundred years. Transmutation. In this twentieth century of our era there are farmers in the world, and not unintelligent, who believe that to some seed of wheat or barley after it has been sown in the field something may happen by which it comes to sprout and grow up into a plant of what they call chess, or cheat; a plant known to botanists as Bromus secalinus; this name itself now apparently destined to perpetuate forever that old opinion — older than his- tory, no doubt — that a grain of barley, secale, may become the parent of a plant of chess. The seemingly indicative facts upon which this transmutation theory appears as if it might have established itself in the minds of prehistoric grain growers were several. Neither chess nor darnel grew commonly elsewhere than in the low wet parts of grain fields. In these spots only very few, depauperate, and almost infertile were the stalks of wheat or barley, though the seed of one or the other had been sown there copiously. The explanation which a very primeval and elementary philosophy could offer was, that the grains of wheat, debilitated to the verge of decay by unusual cold and dampness, became unable to generate a better plant than the small-grained and worthless chess, or cheat, as the farmers still call it. Even Nature herself had taught them with what ease she can, and how every year she actually does effect more mar- vellous transformations, at least in the animal kingdom. The fish-like creatures that swim about in pond and pool in the spring 1 The conifers were favorite subjects of study with Theophrastus ; and if some of our Sequoias are rightly estimated to be twenty-five centuries old, they were not small trees in our philosopher's time. 136 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 months, they had seen come forth in summer, changed to such things as frog and toad. In their simple life, lived very much out of doors, the observingpand intelligent had taken note of how under- ground grub and tree caterpillar by and by assume a larval state, rest in that for months together, and then suddenly are born again, the one as beetle, the other as butterfly. In his environment, the primeval nature student would not doubt the easy possibility, or the apparently strong probability, of some kind of sudden trans- formation in the world of plants; and the well-known frequent ap- pearing of chess in wet ground instead of wheat where only wheat had been planted might be evidence enough of such transmutation. That the supreme philosopher of antiquity, the father of animal biology, who knew so nearly everything about metamorphosis in lower animals, also must have investigated the case of the sup- posed transmutations of plants, appears most probable. For this department of botanical history it may be thought partic- ularly unfortunate that Aristotle's botanical writings have not survived. Theophrastus does not formally and didactically discuss this question, though he makes a number of references to this changing of one plant into another as something universally believed in his day. I shall reproduce a number of them. Recording in one place the usages of his time as to the different seasons of the year and the several methods of sowing cereals, as well as giving a long list of leguminous plants that he names, he concludes the chapter with a remark like this : " None of the above are liable, on account of a bad condition of the seeds, to change into other plants except wheat and barley, which people say may change into darnel (lolium) ; more particularly wheat, and this being said to occur as the result of wet weather, and in muddy places of the fields."1 In the same connection he records it that "Some think flax also changes into darnel." Quotations like these read much as if the author had been unwilling to take the responsibility of either affirming or denying the proposition. "People say" that such metamorphoses occur. But in another paragraph, one relating to different kinds of wheat as imported into Greece from other parts, he affirms that from Pontus, from Egypt, and from the island of Sicily grain-growers of his time obtain seed wheat which matures crops free from lolium; though that from Sicily comes up infested by a different weed called melampyrum, 1 Hist., Book viii, ch. 6. 2 Ibid., ch. 7. LANDMARKS OF BOTANICAL HISTORY — GREENE 137 i. e., black wheat.1 In this report about certain of the imported seed wheat as immune from changeability into lolium, one almost reads between Theophrastus' lines that he regarded the absence from or presence of darnel in wheat fields to be due to the absence or presence of darnel seed in the seed wheat at its sowing. There is another passage in which the philosopher by implication seems to question the wheat-darnel metamorphosis. With the ancient husbandmen as with the modern it was usual to sow wheat either in autumn or in spring. Theophrastus records this, and also says that lolium always germinates in the autumn. He has investigated the case, and gives some points of diagnosis by which young plants of lolium may be distinguished from young plants of wheat.2 This autumnal germination and winter growing of the lolium almost forces upon the thoughtful reader the inference that if lolium occur in a field of wheat that was sown in spring, it was already up and growing at the time the wheat was sown. But there is one phase of this popularly credited metamorphosis doctrine of which Theophrastus is so impatient that he openly denies it. "Some say that barley changes to wheat sometimes, and wheat to barley, and that in the same field. Such statements are to be received as fables. Changes of that kind would be without a cause. It is diversity of condition that induces change." However skeptical Theophrastus may have been about all such pretended metamorphoses, he had doubtless the usual prudential reason for declining to assail them openly at every mention of them. The belief in them was universal; and the time for the elimination of such belief from even thoughtful minds was yet far distant. We find it persisting with men of intellectual attainments as late as the seventeenth century; at which time Scaliger, a most learned commentator on Theophrastus, avers that he himself has witnessed the transformation of wheat into barley and inti- mates that the Greek might have done better than to discredit the phenomenon.4 If it was the metamorphosis attending the development of the individual reptile, and the insect, which helped to elevate to the dignity of a quasi-rational belief the superstition about the change- ability of wheat into lolium, it must be allowed that the reasoning was not very cogent. The cases are not parallel. One is that of the changes in an individual between youth and maturity. In « Melampyrum arvense, ace. to Sprengel, Hist. Rei Herb., vol. i, p. 96. 2 Hist., Book i, ch. 7. 3 Hist., Book ii, ch. 3. * See Stapel's edition of Theophrastus (1644), p. 78. 138 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 the other it is the seed of one species which, ".between the sowing of it and the germination, mysteriously changes to that of another species. There is, however, a phase of transformation in plant life that runs parallel to the metamorphoses of lower animals. This has become generally known only recently, and by means of the com- pound microscope as applied to the making out of the life histories of ferns, liverworts, and other flowerless plants of lower organization. As illustrated in these plants, this kind of individual metamor- phosis could never have become known to the nature students of antiquity, or even to those of the earlier modern epoch, owing to their lack of the necessary optical aids. But somewhat analo- gous metamorphoses take place in the individual life histories of certain higher plants, even of trees; and this fact is not so com- monly known as it ought to be. In the family of the Mimosaceae there is a considerable list of trees which only in the state of seed- lings of a few years old exhibit the usual delicate fern-like doubly pinnated foliage of their family. Before the trees are old enough to flower they have divested themselves of every trace of that kind of leaf and are clothed instead with very narrow, simple, entire, firm and almost leathery organs, in cut somewhat recalling willow leaves, or perhaps better compared to those of mistletoe. Now it will not be in the least to the discredit of a circle of ex- perienced and quite skilful botanical amateurs of the Northern Hemisphere if, placing before them two branches of such an acacia, one from the ferny-leaved young tree, the other from the mature tree with its stiff phyllodes like mistletoe leaves, and stating that these two branches represent one and the same species of Australian acacia, the whole circle of them suspect at first that I may be jesting. Some of the Australian eucalyptus species undergo as complete a metamorphosis in the individual, with this difference that the adult tree, at least in the earlier stage of maturity, ex- hibits both phases of branch and foliage ; the lower and flowerless portion of the head of the tree seeming to represent one genus, the middle and upper branches — those that have the flowers and fruits — seeming as if they must be those of another genus, or even of another family. It is quite as if the tree at a point just below midway of its axis, had become by grafting from that point upwards a tree of another genus. Of \hese changeable acacias and eucalypts the ancient Greeks of course knew nothing; but they were familiar with a similar case, that of what is known in very modern botany as Hedera Helix, LANDMARKS OF BOTANICAL HISTORY — GREENE 139 the English ivy. This, as they well understood, is most commonly seen as a trailing or climbing shrub, the stems rooting everywhere, all the foliage leathery, of angular outline and dark green. In this phase the plant may pass the whole of its existence and remain flowerless. Occasionally, when very old and having climbed by wall or tree trunk to sunlight and upper air, a new thing happens. Out of the summit of this dark-green creeping ivy mass an upright bush appears; its branches not rooting, firm, independent, bearing leaves not leathery in texture, not in the least degree angled, and even of a decidedly light green; and this bush up at the top of the ivy will in course of time bear flowers and fruits. The ancients before Theophrastus had no difficulty in explaining this phe- nomenon. Their firm belief in all sorts of transmutations as taking place in nature saved them any perplexity. They held these two phases of the ivy to be generically distinct, and had their fully established names for the two genera: Helix for the rooting and climbing plant of dark angular foliage, Cissus for the upright bush of the pale thin ovate leaves, that into which the Helix sometimes in old age transformed itself. | Again Theophrastus fails to be satisfied with the popular philosophy, and suggests one that he thinks more rational. If every plant of Helix under the right conditions and with fair opportunity would develop a Cissus bush at summit in maturity or old age, which he says some agree to as being probable, then he would be of the opinion that the distinction between the two is not a generic one, but only a matter of the age of the individual.1 He who has taken note of this philosopher's way of advancing his most revolutionary propositions with urbane reserve will under- stand him as here pronouncing against the time-honored doctrine of a generic change from Helix to Cissus, and as averring that these are but the young and the old phases of one species. It was the inductive philosopher, the scientific botanist, undermining as it were by stealth an ancient botanical superstition, because he had a truly scientific proposition to put in place of it. In this instance Theophrastus was, as usual, far in advance of his own time. For centuries after him men still held to the bigeneric ivy. I should confidently expect to find this pre-Theophrastan view surviving still among the peasantry of some parts of Europe where Hedera Helix is common and well known. Living in the midst of a time when a thousand superstitions prevailed everywhere concerning plants, their origin, magic powers, 1 Hist., Book iii, ch. 18. 140 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 and their often grotesque metamorphoses, it is greatly to the credit of Theophrastus that he should have risked something of his own popularity as a teacher and author by expressing, even covertly, some of his own doubts and disbeliefs; even as to some, the truth of which seemed so probable that the belief in them is not yet in our time obsolete. Recapitulation. Certain opinions that are completely groundless respecting Theophrastus' merits as a botanist, opinions quite opposite to any that had ever before been expressed, and such as no man who had read three chapters of that author could have entertained, have been widely disseminated during the last thirty years. One such statement of opinion is before me and reads thus: " Greek authors built their views of the philosophy of botany on very weak foundations; scarcely a plant was known to them exactly in all its parts; they derived much of their knowledge from the accounts of others, often from dealers in herbs. From this scanty material, and from various popular superstitions had Aristotle formed his views on the nature of plants; and if Theo- phrastus possessed more experimental knowledge, he still saw facts in the light of his master's philosophical doctrines."1 Such reckless writing as that, betraying innocency not only of Theo- phrastus' work, but also of that high opinion of it which had been expressed by most accomplished botanists of the eighteenth century and the nineteenth, has been widely read by botanists -of the present generation. In view of this, it seems more than de- sirable that there be presented briefly and synoptically something like an enumeration of those items, or elements, of universal botany of which Theophrastus appears to have been the discoverer and first promulgator. In this recapitulation I shall employ a few modern terms, such as petal, corolla, and andrcecium, unknown to ancient Greek botany, that I may thereby both more clearly and more briefly express the fact of the Greek's having recognized, though under other names, the things themselves. 1. He distinguished the external organs of plants, naming and discussing them in regular sequence from root to fruit ; the natural- ness of which sequence was afterwards pointedly denied; but in modern botany it stands everywhere approved. 2. He classified such organs as (a) permanent, and (b) transient; a division of them which may yet be shown more scientific than the modern distinguishing of them as (a) vegetative, and (b) reproductive. 1 Julius Von Sachs, History of Botany, English edition, p. 16. LANDMARKS OF BOTANICAL HISTORY GREENE 141 3. The existence of aerial roots, as being of the nature of roots, and thus different from tendrils and other prehensile organs, was discovered by him and has never since been disputed. 4. He remarked upon the inconsistency of retaining in the category of roots certain enlarged, solidified, jointed, and otherwise peculiar underground parts ; a suggestion which lay unheeded during two thousand years of botanical history, and has only recently led to the open recognition of the category of subterranean stems. 5. He recognized, by differences of size, solidity, and other par- ticulars of structure, three classes of stems : the trunk, stalk, and culm. 6. By never speaking of calyx and corolla as peculiar and separate organs, but always referring to their parts as leaves merely, it is evident he regarded the flower but as a metamorphosed leafy branch ; to which forgotten Theophrastan philosophy of the flower1 neither Goethe nor Linnaeus had but returned, when each supposed himself the discoverer of a new anthogeny. 7. He divided the plant world into the two subkingdoms of the flowering and the flowerless. 8. The subkingdom of the flowering he again saw to be made up of plants leafy-flowered and capillary-flowered; really the dis- tinction between the petaliferous and the apetalous; one the deep import of which was first realized and taken advantage of by the systematists of some two centuries ago. 9. He indicated the still more important differences of the hypo- gynous, perigynous, and epigynous insertion of corolla and andrce- cium. 10. He distinguished between the centripetal and centrifugal in inflorescences. 11. He was first to use the term fruit in the technical sense. as applying to every form and phase of seed encasement, seed included; and gave to carpology the term pericarp. 12. He- classified all seed plants as (a) angiospermous and (6) gymnospermous . 13. Respecting the texture and duration of their parts he classified all plants as tree, shrub, half-shrub, and herb; also noted that herbs were of perennial, biennial, or annual duration. 14. He indicated with clearness several of those differences in the structure of stems, leaves, and seeds by which the botany of later times separates plants monocotyledonous and dicotyledonous. 15. He described the differences between the excrescent and deliquescent in tree development. 1 Reaffirmed and somewhat improved by Cesalpino in the year 1583. 142 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 1 6. He knew how the annual rings in the stems or trunks of certain woody growths were formed. 17. Theophrastus, with natural vision unaided by so much as the simplest lens, and without having seen a vegetable cell, yet distinguished clearly between parenchyma£ous and prosenchym- atous tissues; even correctly relating the distribution of each to the fabrics of pith, bark, wood, leaves, flowers, and fruits. This list of facts botanical which Theophrastus saw, and in the main discovered, is not complete, but it embraces well-nigh all the first rudiments of what even to-day is universal scientific botany. It illustrates superabundantly the fact that Theophrastus, and no man of any later time, is the father of the science as we now have and hold it. And in the light of the above partial recapitu- lation of his discoveries, what possible remark could be more inane than this? "If Theophrastus possessed more experimental know- ledge [than Aristotle], he still saw facts in the light of his master's philosophical doctrines. " When a man has firmly laid the foun- dations of a science, and then has added the suggestions of almost the whole superstructure, what faintest shade of pertinency can there be in asking what his philosophic doctrines were ? As reason- ably might one leave any scientific work, alive with new facts, quite unexamined because its author's philosophy was that of a school unpopular, or his creed unorthodox. The most generous interpretation of the words quoted would seem to be, that their author, having no knowledge of Theophrastus, thought to absolve himself from the task of acquiring it by trusting that the Greek would never again be found worth studying. To me it seems not improbable that historians of the future, learning to know this great founder's mind better than it is yet known, may agree in some judgment not unlike this: that all that has been added' to the understanding of plant life and form — to morphology, anatomy, physiology, perhaps even to taxonomy — within the last three centuries has been due to the inventions of the opticians, and to the increased number of students and inves- tigators, rather than to the appearing on the botanical horizon, within the modern period, of any one mind in powers of observa- tion, penetration, and sagacity superior to Theophrastus of Eresus. Plumier (1703) sought to commemorate Theophrastus in a newly discovered genus of West Indian shrubs, yet was so inconsiderate as to name the genus ERESIA. This Linnatus (1740) changed to THEOPHRASTA. CHAPTER III GREEKS AND ROMANS AFTER THEOPHRASTUS LEAVING Theophrastus, and going forth in search of the next landmark in the progress of our science, we seem at once to enter an almost boundless pathless waste. Or, as the outlook has been described by another: "If history be a connected succession of events, botany from Theophrastus forward to the sixteenth cen- tury has no history. Only isolated pieces of information, like bits of wreck half buried up and down stretches of seaside sand are left. These are connected with certain names; but, beyond that, are hardly of historic import. Of written monuments of real botany in the Greek language after Theophrastus there remains not one. For the small volume of Nicolaus Damascenus, known to us only by a translation into barbarous Latin, perhaps might, and possibly might not, have been reckoned such a monument."1 What is here understood is, that a great multitude of scattered fragments, together with several completed pieces of writing about plants that, out of the literature of antiquity, have been preserved do not afford material for the history of botany for so much as one only of the ten centuries that next succeeded the times of Aristotle and Theophrastus; and that this is true partly for the reason that the pieces and the fragments that have reached us are from men who were not botanists after the order of Theophrastus, but writers on medical, agricultural, and horticultural botany. That the whole number of Greeks who wrote of plants in one way or another was very great there is evidence enough. As many as three hundred and fifty years ago the learned botanist, zoologist, and bibliographer, Conrad Gesner, gave out a printed list of more than one hundred names of Greeks who, in his day, were known to have written more or less botany.2 Of ancient Latin authors of botanical works similar to those of the Greeks in kind, the same 1 Meyer, Geschichte der Botanik, i, 202. 2 This in one of the several valuable papers that are prefatory to Hierony- mus Tragus' De Stirpium Historia, 1552. 144 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 distinguished bibliographer enumerates ten or twelve; but does not seem to have quite finished that catalogue. As considerable a number of Arabian medical botanists of a less ancient period is also given. The best of those botanical fragments, gathered in as it were from the wreck of ages, were what really inspired the first begin- nings of modern botany in the sixteenth century. From the time of the establishment of universities and better schools of medicine in the middle ages, the best text-books of pharmacy were those of the ancients, Hippocrates, Nicander, Dioscorides, Pliny, Galen, and as many more less celebrated than they. The remedies in use were almost wholly vegetable, as were also the poisons and their antidotes ; and the old authors' books were the topics lectured on in every school, and their plant descriptions were trusted to for the correct identification of plants alimentary, medicinal, and poisonous. And so, not even from the simplest outline of botanical history may all mention of the old Greek, Roman, and Arabian agricultural, horticultural, and medical botanists be omitted. We are not indeed able to construct out of their literary remains' a botanical history of their period; but we know that they became at last, and inci- dentally, the inspirers of a new epoch which dawned upon botany a thousand years or so after the last of their line was dead. Sketches of the life and work of a few of them, and only such as came after Theophrastus, will here find place. NICANDER OF COLOPHON. — This Greek grammarian and poet flourished in the second century before the Christian era; was native of a small village, Claros, close by Colophon in Ionia, and was anciently known as the Colophonian Nicander by way of distinction from others of the name of Nicander. He was of great renown as a poet, and his topics were mostly such as invite to the consideration of the living things of field, forest, and wilderness. Evidently Nicander was a naturalist, also learned in pharmacy and toxicology, and chose to express himself in poetic measure. That which may have been his most elaborate work has been lost, that is, the Georgica, a versified treatise of agriculture praised by Cicero,1 and extensively quoted by Athenaeus,2 whose quotations are all that remain of the poem. Among these remnants, there is a long passage on flowers and other ornamental plants, an account of the Egyptian nelumbo, a dissertation on poisonous fungi — the earliest on record — and even another on the cultivation of edible 1 Cicero, De Oratore, Book i. 3 Athenaeus flourished some three centuries after Nicander. LANDMARKS OF BOTANICAL HISTORY GREENE 145 mushrooms, besides many things relating to various other food plants. 1 The only works of Nicander that have reached our time are two poems, under the somewhat lugubrious titles Alexipharmica, a treatise on poisons in general and their antidotes, and Theriaca, on poisonous animals. The first of these, according to Meyer,2 who appears to have read both of them carefully, is of 630 verses, and has under discussion 21 different poisons, of which 2 are mineral, 8 animal, and n vegetable products; and the remedies for them are with hardly an exception vegetable. The account of the symptoms of different poisonings is said to be both true to modern experience and vividly drawn, but the plants themselves, whether poisonous or antidotal, are hardly more than named, never described, and the book as a whole is devoid of matter properly botanical. In the Theriaca, a more extensive work of 958 verses, botany, as well as zoology, fares somewhat better. After a preliminary statement of means of frightening away poisonous animals or keeping them aloof, together with certain precautions to be ob- served by such as sleep out of doors at night, there follow some descriptions of certain more common and dangerous kinds which are often drawn with remarkable exactitude and faithfulness to nature. And here again, the bites and stings of these have always their remedies in certain plants, of which also in most cases only the names are given, though sometimes a few hints are given as to how the plant may be identified. The three particular plants, centaurea, aristolochia, and trifolium, are together efficacious against every poisonous animal's bite or sting. The identity of Nicander's centaurion is uncertain. It may have been Hypericum olympicum, but that of Theophrastus, whom Nicander often quotes, is Ferula opopanax more probably. The aristolochia is that of modern botany, the species either A. rotunda or A. longa or both. The only trifolium known to the Greeks was our Psoralea bitumi- nosa. In the two poems thus adverted to Meyer counted the names of 1 2 5 different plants. 3 Sprengel gives a list of some thirty species of Nicandrian plants which, though not in all cases identifiable with certainty, seem to have been first mentioned by this writer. 4 Adanson in 1763, resolving to dedicate a genus of plants to 1 Haller, Bibliotheca Botanica, vol. i, p. 54. 2 Meyer, Geschichte der Botanik, vol. i, p. 247. i Ibid., 248. 4 Sprengel, Hist., vol. i, p. 129. 146 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 Nicander, doubly distinguished himself in so doing; for NICANDRA not only commemorates a worthy name in old Greek plant lore, but the type that was to bear the name was with an exquisite sense of fitness chosen from out the family of the nightshades. MARCUS PORCIUS CATO (B. c. 235-150). — An illustrious Roman of vigorous mind and great originality, serving the public in the most exalted and responsible offices with great acceptance, affluent as to means, he lead a life of great simplicity, temperance, and frugality, delighting in nothing else so much as the training of his children in virtue, and cultivating flowers and fruits. Practically a philosopher indeed himself, Cato held in abhorrence the philoso- phies of the Greeks, was strongly averse to the introduction of Greek art and Greek customs into Rome, apprehending the destruction thereby of Roman valor and simplicity, and recalling his son from the study of Greek. Later in life Cato must have fallen captive to the charms of Greek erudition; for he himself mastered the language, and on a visit to Athens addressed a concourse of the people in their own tongue ; and it is observed that his own writings have quotations from Greek authors. The literary monument that immortalizes Cato the Censor is his De Re Rustica, a treatise on farming, gardening, fruit growing etc. It is the oldest book of its kind in Latin literature, and therefore is of botanical interest. We learn from its pages that almost every method of propagating choice varieties in use with twentieth-century pomologists and vineyardists was practised by Cato long before the beginning of our era, even to the different modes of grafting; and there is no intimation that any of those methods were other than ancient at that time. The number of named varieties of things which they had and were careful. to perpetuate is also sufficiently interesting to merit such exemplification as I here subjoin, culled from Cato's book: Brassica crispa Myrtus alba. Brassica erratica Myrtus nigra Brassica lenis Myrtus conjugalis. Brassica laevis Ficus marisca. Olea albiceris Ficus Africana. Olea Colminiana Ficus Herculana. Olea conditiva Ficus hiberna. Olea Liciniana Ficus Saguntina. Olea Salentina Ficus Telana atra. Olea Sergiana Vitis aminea majuscula. LANDMARKS OF BOTANICAL HISTORY — GREENE 147 Pirus Aniciana Vitis aminea minuscula. Pirus cucurbitina Vitis Apiciana. Pirus mustea Vitis gemina. Pirus sementiva Vitis helvola. Pirus Tarentina Vitis helvola minuscula. Pirus volena Vitis Lucana. Vitis Murgentina. All this would pass readily for good twentieth-century botanical nomenclature ; but these names are easily two-and-twenty centuries old. No fewer than five genera dedicated to Cato have been proposed, by as many different botanical authors, each apparently unaware of the attempts of the others. The CATONIA of Patrick Browne (1756) has priority. MARCUS TERENTIUS VARRO (B. c. 117-27). — In so far as the mastery of human learning gives distinction, Rome had in Varro the most distinguished personage of all whose names adorn the pages of her ancient history. One Symmachus, who lived four centuries later, and whose letters are extant, wrote to a friend: "You know the writings of Terentius, not the comedian, but the Reatine, the father of Roman learning." r This Terentius was sometimes called the Reatine in allusion to his birthplace, which was the small village of Reate — now Rieti — some ten miles north of Rome. The family was plebeian, but there had been gifted scions of it before this one, and there were others after him. A century before him there had been a consul Caius Terentius Varro, chosen by the tribunes of the people for the reason that he was of the common people.2 Concerning the childhood, youth, and even the early manhood of Varro, and under what conditions the passion for learning was developed, nothing seems to have been recorded; and we seem to obtain our first certain view of him as in the public service under Pompey in the war against Mithridates; but he is then fifty years of age. Also at seventy he is still a naval commander. Being a man of great wealth, owning extensive landed possessions in several provinces, and having acquired so costly a thing as a great library was at that time, the fact of his having devoted his energies to the military service of the Pompeys and Caesars for so long a period has not seemed easy to account for. In these chances of war certain of his richest estates were confiscated, and his library > Quoted by Meyer, Geschichte der Botanik, vol. i, p. 356. a Livy, vol. xxii, chs. 34, 35. 148 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 was plundered, this event entailing the loss of not a few of his own writings. And all the while his own tastes and preferences were for the life of quiet study, with rural avocations for his pastime. Varro was more than seventy years of age when Julius Caesar, returning to Rome as the great victor, recognized him as the most learned man of his time, and charged him with the work of collecting and arranging a great library; a noble scheme which Caesar's assassination a year or two later brought to naught. After that, under the triumvirate of Antony, Augustus, and Lepidus, Varro's name was placed on the list of the proscribed; but by help of his friend Calinus, who concealed him in his own villa, his life was saved until this storm was past. The remainder of his life was given undisturbedly to literary work. His industry as an author has made Varro a wonder to succeeding generations. He wrote long treatises on Antiquities, a History of Literature, another of Philosophy, another of primitive Rome, a History of Religion, a volume on Education, a Latin Grammar, a book on Navigation, and unnumbered other treatises, all, or nearly all, long since lost, though referred to by many contemporaries. His treatise on Agriculture, in three books, almost alone of all his writings, has survived. He tells us in the first chapter of the work that he begins the writing of it in his eightieth year. It is replete with learning of all kinds, and is still a practical treatise ; yet also evincing the author's familiarity with those Greek authors who, like Aris- totle and Theophrastus, wrote on the theories of plant life and form. As compared with Cato, the list of Varro's cultivated plants is not as long, and he does not enumerate as many varieties of Brassica, Pirus, Myrtus, and other genera. The choice varieties of cultivated cherries, long known in Pontus, Varro adds to the list of Roman fruits. He is first among Roman authors to take note of certain phenom- ena of plant life, such as the growth and development of leaves and flowers, and also certain movements. The leaves of the olive, white poplar, and willow, whitened underneath, are apt to become inverted so as to show the lower face, and this at about midsummer, which phenomenon they take for a sign of the arrival of the solstice. The flowers of heliotrope follow the course of the sun from morning until nightfall; and there are other kindred observations, with even a hint that there is a physiology of such things that it might be interesting to know something of. In a passage on cattle raising one of Varro's interlocutors is represented as saying: "The thing is so, but why it is so, that is your affair, you LANDMARKS OF BOTANICAL HISTORY — GREENE 149 who read Aristotle."1 By such tokens is Varro more a botanist than Cato. True, he has derived every one of these ideas from the Greeks, not one of the observations being original with himself; but it was something to have been first to call the attention of Romans to them. Patrick Browne (1756) sought to establish a genus VARRONIA. It seems that the name is untenable; the same genus having been named Cordia more than a half century earlier. PUBLIUS VIRGILIUS MARC (B. c. 71-19). — Virgil, who has often been designated the prince of Latin poets, was born at Andes, a small village near Mantua, some seventy years before the beginning of the Christian era. His early years were passed at Cremona, where his father had valuable landed possessions. These were among the lands which, after the battle of Philippi, Augustus Caesar confiscated, distributing them to his veteran soldiery. On this occasion the future poet was near losing his life through attempting to dispute with the soldiers, the possession of his fields. He escaped by swimming across a river, and then Virgil with his father repaired to Rome. It was .the beginning of his greatness. His presence, manners, and accomplishments recommended the young man to the great Mascenas, the power behind the throne of Augustus, and the latter soon restored to Virgil his lands; and the emperor's reward for this kindness was the ten pastoral poems (Bucolica) composed in the course of the next three years, and dedicated to the imperial benefactor. After these followed the Georgica, accounted the most perfect and finished of all Latin compositions. The simple narrative of the poet's career at Rome, and elsewhere until his rather early death, is one of the most fascinating and beautiful chapters in all history, but for several reasons must not here be presented anew. The Georgics, by which Virgil is even more favorably if less universally known than by his unfinished epic, the ALneid, treat of agriculture and gardening; but also again one must refrain from anything like a botanical analysis of the poems. It may suffice to indicate how prolific a field for botanical research the poems of Virgil long have been. The following list of works on the Virgilian botany is doubtless incomplete.

John Martyn was a physician, and Professor of Botany at Cambridge, the friend of Sherard, Sloane, and Dillenius, and was the first to establish the fact of this poet's profound knowledge of plants. Both the works named were in so great demand among men of erudition as to have been several times reissued, and in octavo form. A German translation of Martyn's edition of the Georgica was published at Hamburg in 1759. 1 (3) Flora Virgiliana. Eller forsok at utreta de waxter som utforas i P.

Although Virgil was by profession a man of letters and a poet, he nevertheless exceeds the other agricultural writers of Roman antiquity in the number of different plants which he knows, and of which he makes mention; for Cato (B. c. 235-149) knew 125 kinds, Varro (B.C. 117-27) mentions 107, Virgil (B.C. 70-19) 164. Yet the sum total of the plants of these Romans, 245, is only about half the number that had been known by Theophrastus some 300 years earlier. The celebrated Lamarck (1793) dedicated to Virgil a new genus of African trees under the name VIRGILIA. Lucius JUNIUS MODERATUS CoLUMELLA. — This very celebrated Latin writer on agriculture and horticulture nourished in the next generation after Virgil, during the reign of Tiberius Caesar, and may have been in the midst of his years at the opening of the Christian era. He was a native of Cadiz in Spain, and was educated by his father, whom he characterizes as having been a man of erudition and also an experienced practical farmer. 2 The son declares himself to have been what one would now call an omnivo- rous reader, and before settling in Rome had travelled somewhat widely in Greece and Syria. Columella is the most voluminous of all the classic Roman authors on rural topics. There are thirteen books, and these » Haller, Bibl.

LANDMARKS OF BOTANICAL HISTORY — GREENE 151 aggregate some two hundred and sixty chapters, mostly long ones, and if none of the chapters are very strictly botanical, the whole work is a treasury of information about ancient husbandry, and the treatment of cultivated plants and trees. From him we have the earliest account of the device called a hot -bed, heated from beneath by a mass of fermenting manure, and protected from the rigors of winter weather by panes of glass. He reports that by these means Tiberius Caesar raised cucumbers all the year around. i To Columella we are again indebted for a complete account of the methods of grafting as practised by the ancients.2 Sprengel has given a considerable list of plants and trees that are first brought to notice by this author.3 Near the end of the eighteenth century two distinguished botan- ists almost simultaneously bethought themselves of the propriety of consecrating a genus to Columella. The COLUMELLIA of Ruiz and Pavon (1794) appears to have the priority. PEDANIOS DIOSCORIDES (about A. D. 64). — If to have written the most practically serviceable book of botany that the world of learning knew of during sixteen centuries were the best title to botanical greatness, to Dioscorides would readily be conceded the absolute supremacy over all other botanists, not only of antiquity but of all time. Concerning the duration and the absoluteness of his supremacy Sprengel has the following : ' ' During more than sixteen centuries he was looked up to as the sole authority, so that every- thing botanical began with him. Every one who undertook the study of botany, or the identification of medicines swore by his words. Even as late as the beginning of the seventeenth century both the academic and the private study of botany may almost be said to have begun and ended with the text of Dioscorides."4 Almost volumes have been written in controversy as to the time when Dioscorides lived; though the extremes of opinion do not assign him an earlier date than B. c. 30, or a later than A. D. 98 5 ; and the most probable seems to be that which locates him in about the middle of the first century of our era. That he lived in the time of Nero is inferred almost to a certainty from remarks of Tacitus and of Galen. 6 1 De Re Rustica, Book xi, ch. 3. 1 Ibid., iii, ch. n. 1 Hist.

Rei Herb.t i, 152. 152 SMITHSONIAN' MISCELLANEOUS COLLECTIONS VOL. 54 Though in relation to this author biographic dates fail us, the land of his nativity does not. It is well established that he was a Cilician Greek, his native city being Anazarbos; for in order to distinguish between him and others named Dioscorides, eminent writers referred to him as Dioscorides Anazarbaeus, the Anazarbean Dioscorides. It is clear also from his own writings that he was a learned physician and practised medicine; also that he had travelled widely to study plants, and obtain knowledge of other than vegetal remedial agents. In these travels he came to know many plants before unknown to Greek and Roman physi- cians, and was at the pains of describing many such; that is, of indicating not only their qualities and remedial effects, but also something of their aspects and morphology as living plants ; describ- ing their roots, stems, foliage, and even sometimes their flowers; and the number of plants and plant products of which he gives account is about 600. Such a list of merely medicinal and alimentary plants is by more than 100 greater than the sum of all plants known to Theophrastus three centuries before Dioscorides. And it was because he had described so many, and often so well, that in after ages he came to be regarded as the supreme botanist. The usefulness of his medical botany, from the phytographic point of view, was not only fully realized, but also enthusiastically somewhat overestimated. The scientific botanist among the Greeks was Theophrastus ; and there is no comparison between him and Dioscorides, whose theme was medical botany; but, quite as usual, the man of "applied science" was the one to meet with general appreciation and approval. So highly esteemed was Dioscorides during the middle ages, that early after the invention of printing, his work, though in Greek, obtained an editor and a publisher at Venice as early as the year I499-1 This edition must have obtained a ready sale, for in 1518 it was repeated. A third Greek edition appeared at Basle in 1529.2 Latin being the universal language of the schools, Latin versions of Dioscorides were in demand, and early became rather numerous. The very first of these, a book rare and obscure, purports to bear the date I478,3 thus antedating the first Greek prints. But from the year 1516, when the first excellent translation by Ruellius appeared, Latin versions became numerous ; and for a whole century thereafter the most voluminous and most useful books of botany were in the 1 See Pritzel, Thesaurus, 2d ed., p. 84. » Ibid. 3 Said to bear the name of Petrus Paduanensis; see Pritzel, ad ed., p. 85. LANDMARKS OF BOTANICAL HISTORY — GREENE 153 form of commentaries on Dioscorides. Such in large part are the works of Anguillara, Matthiolus, Maranta, Dodonaeus, Cesalpinus, Fabius Columna, and the Bauhins. In several of these the annota- tions and comments quite exceed in bulk the Dioscoridean text, and are replete with new botany; that is, they contain the names and descriptions of many plants which the commentators are con- vinced Dioscorides did not know, and which they therefore judge to be new. One may fairly say that the greater part of all the new botanical matter published during the whole of the sixteenth century, and a part of the seventeenth, came out in the form of annotations upon the text of Dioscorides. Thus it appears that the Greek, who only meant to provide medical students with a full compend of remedies, and of the marks by which to know them,1 became incidentally the first master of phytography ; the one every line of whose plant descriptions has been more attentively studied word by word, and that by a greater number of erudite men than any other book about plants that has yet been written ; unless one should possibly be obliged to make an exception of Bauhin's Pinax. But even that is, first of all, a compend of Theophrastan and Diosco- ridean phytography, together with such augmentations and im- provements as in the year 1623 were found necessary. Latin editions of Dioscorides are too numerous to be given a reckoning; and almost the same may be said as to early translations of him into modern tongues; for between the years 1555 and 1752 there were at least twelve Spanish editions, as great a number in Italian, and there were editions in French in 1553, 1559, and 1580. There was one translation into German as early as 1546, another in 1610, and this last appears to have been issued again in 1614. i Little in the way of botanical taxonomy will be looked for in a work on pharmacy that is nearly nineteen centuries old. The most comprehensive of his groups are formed according to properties ; thus his Book I is devoted to the consideration of plants that are of merely aromatic rather than medicinal qualities; growths that furnish oily, gummy, or resinous products, such as enter into the composition of salves and ointments; and after these follow the trees that yield fleshy fruits of grateful though not specifically aromatic flavors. Book II, beginning with animals, and animal products that are of dietetic and medicinal use, ends with the cereals, the leguminous, malvaceous, cruciferous, and other garden herbs. Then Books III and IV deal with a vast number of plants more distinctively medicinal. 1 Pritzel, Thesaurus, 2Bibliotheca Botanica, vol. i, p. in. 2 Meyer, Geschichte der Botanik, vol. ii, p. 191. LANDMARKS OF BOTANICAL HISTORY — GREENE 163 endeavor to familiarize himself with the medicinal plants of different climes, and when one has marked the keenness of his powers of observation everywhere, it is impossible to agree with the learned Haller that in botany Galen was inexpert ; nor can it reasonably be questioned that had he betaken himself to phytography, he would have laid all botanical posterity under deep obligations to himself. Now, that he did not describe plants, but was accustomed to give their names only, or but little more, one might have been disposed to charge to the fact of his having flourished in the very next century after Dioscorides whose 600. species, embracing the whole vegetable materia medica, may have been for the most part well identified at Galen's period, so that the mention of a name only would suffi- ciently recall a species. But such apology for Galen would be super- fluous. The truth seems to be that he had next to no faith in phytography at all. He takes openly the ground that " The identi- fication of plants is better accomplished by the actual observation of them under the help and guidance of a teacher, than by that method which may be likened to the attempting to learn to navigate the seas by studying books on navigation."1 This, then, is the main reason why Galen almost abjured plant description. The passage is luminous with historic information about the study of botany in the Rome of eighteen centuries ago. We know already that at this period the occupation of a well trained physician is lucrative. There are many of them; therefore the candidates for the profession are not few. The remedies in use are almost all botanical, and they all study botany; quite otherwise, by the way, than botany is studied in twentieth-century schools of medi- cine, and less perfunctorily. Unless in their practice of medicine they are to be at the mercy of the unscrupulous among herb gather- ers and drug vendors, they must know the marks of the genuine thing. Therefore important among their regular exercises is that of identifying plants, the book open before them, the specimen it may be a withered and shrunken root or rootstock, not improbably supplemented by a fresh one newly brought in from its native soil, or from some drug garden. The standard botanical work, descrip- tive and pharmaceutical, is Dioscorides — its author hardly a century dead — and there are others. The descriptions are mostly brief and often inadequate, so that mere guesses at the identity of things frequently pass instead of certainty, and about the identity of some that are of remedial importance the whole fraternity — Galen himself perhaps excepted — is wrong. At all events none 1 Galen, ed. Kiihn, vol. xi, p. 96. 164 SMITHSONIAN MISCELLANEOUS COLLLECTIONS VOL. 54 but he is so discouragingly aware of the multitude of errors that have originated through placing dependence on descriptive botany. He thought there was a better way; but this proposal of his seems to imply on his part an overweening confidence in the perpetuity of things. He did not foresee a time when the race of capable phytognosts would fail, and when in default of such teachers for the identifying of plants there would be no other dependence at all but the old and often imperfect descriptions. Men follow great leaders when the leaders are in the wrong, about as faithfully as when in the right; and if, during several centuries after Galen, lesser lights continued to mention plants hardly more than by their names and remedial qualities, it was after the example of his authority as supreme. In such manner may the most expert man of science chance to antagonize the best interests of that science, and heavily impede its progress along one line while advanc- ing it in a different direction. His indifference to phytography notwithstanding, Galen has been credited with having made some few additions to the list of known plants by new name, and by some sort of description. Michel Adanson attributed the discovery and the naming of two new genera to Galen. They are Lycopersicon 1 and Arctostaphy- los.2 Both names are now in use for genera, but it is impossible to identify either one with the type which Galen had in hand; but from such description as the Greek gave out, his Arctostaphylos would be V actinium Arctostaphylos rather than Arctostaphylos wua ursi. • In the year 1737 Linnasus dedicated a genus GALENIA to the memory of Galen. 1 Adanson, Families des Plantes, vol. ii, p. 572.

CHAPTER IV INTRODUCTORY TO THE SIXTEENTH-CENTURY GERMAN FATHERS / THAT long course of ages intervening between the last decline of the Roman empire and the revival of learning in the fifteenth century is chiefly distinguished botanically by what we do not know about it. Even the historians of botany, with hardly more than a single exception,1 instead of making intelligent and unimpassioned use of the scattered fragments of botanical record for the period, have done what they could to perpetuate their own hereditary prejudices against the whole period. 2 However, he who is in quest of landmarks chiefly will be absolved from the task, interesting though that would be, of following the vicissitudes of botany through the middle ages. The period has not apparent landmarks of botanical history. /The tenor of the German waiting of its history is, that the science of botany was born again, as it were, in the year 1530 and in Germany, by the publication of Otho Brunfelsius' folio entitled Herbarum Viva I cones — Living Pictures of Herbs. The Germans have always been and are the chief historians of botany. I pay full tribute of acknowledgment to their supremacy in this field of high endeavor when for the heading of this chapter I adopt what is become their own favorite caption. All of them use it: Kurt 1 Meyer alone (Geschichte der Botanik, vols. iii and iv) has treated the subject of botany in the middle ages with impartiality. 2 Emphatic examples of this kind of writing in the name of history are in Sprengel's Historia Rei Herbarics, vol. i; particularly his chapter on "Monastic Botany," pp. 222-228, and on the " Latinobarbarous Age," pp. 274-299; wherein even concerning the botanical volume of Albertus Magnus he says, "Let him read it who has time to throw away"; though Meyer, only a half-century after Sprengel, and as much an antimonachist as he, devotes seventy serious pages of his history to the merits of this same Albertus of the middle ages. 165 {66 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 Sprengel, 1 Ernst Meyer,2 Emil Winckler,3 Julius von Sachs.4 All of them name Brunfels, Fuchs, and Tragus (Bock) as the fathers of the new botany of modern times. It has been indicated in a preceding chapter of these Landmarks that the real father of botany as a science was Theophrastus of Ere- sus. If he is the father of the science he is the father of even modern botany, though not of those developments of it that have been the peculiar achievement of modern botanists. Science is truth. The foundations of a science are its fundamental truths, and so the foundations of a science once laid are laid forever. These things are self evident. We shall not be able to realize in how far the "German Fathers" contributed to the superstructure of modern botany until we have examined with great care and diligence their best works; and this is something which, I shall make bold to say, not even the German historians have been at the pains of doing; though Sprengel, first of their lineage, did much and well in this direction, while also leaving very much for others to accomplish. Julius von Sachs, the latest in the line, copied Sprengel's caption " The German Fathers," etc., but knew next to nothing of their works, even rating as unimportant Valerius Cordus,5 who was immeasurably the greatest of them all. The four now named represent two rather distinct kinds or grades of botanical work. Brunfels and Fuchs busied themselves almost wholly with medical botany. It is a rare thing with either of them to mention a plant of unknown or even uncertain medicinal or alimentary qualities; and their plant descriptions are almost as uniformly either compiled or literally copied from authors of centuries and even almost thousands of years before them. The books of Tragus and of Cordus abound in new and original descrip- tions. These demonstrate that these two men examined plants with their own eyes, and for the love of them as plants, and that they saw many things about the structure and the behavior of them to which the other two men, and even all botanists before them, had been blind. There is another contrast. Brunfels and Fuchs, realizing the defects of many of the ancient descriptions, sought to render the • Historia Ret Herbaria, 2 vols., 8vo, 1807-1808. 2 Geschichte der Botanik, 4 vols., 8vo, 1854-1857. 3 Geschichte der Botanik, i vol., 8vo, 1854. « Geschichte der Botanik vom 16 Jahrhunderl bis 1860, i vol., 8vo, 1875. * Geschichte der Botanik, p. 31. LANDMARKS OF BOTANICAL HISTORY GREENE 167 identification of remedies more easy and certain by supplying engravings of ths plants. This idea was very far from being new; indeed, it was almost as old as botany. Pliny knew as many as three Greek authors who, before the Christian era, had illustrated their manuscripts by paintings of the plants.1 The traditions of still others have been brought to light. In the middle ages early and late rare manuscripts of old botanical authors illustrated by draw- ings or paintings of plants were known and referred to. The most noted of such ancient manuscripts, now some thirteen centuries old, has been reproduced photographically, and in this way actually pub- lished since the beginning of the twentieth century.2 Even forty or fifty years before these fathers of plant iconography, there were printed copies of the Hortus Sanitatis,3 and of its German version, Gart der Gesundheit, illustrated by some five hundred wood engrav- ings of plants. Doubtless the wretched character of those first printed plant pictures, along with the fact of the great popularity of the books containing them, were what moved Brunfels to undertake the production of the Herbarum ^riv& Icones; and the success of his enterprise stimulated Fuchs to inaugurate a larger one. These two might worthily have been styled Fathers of Plant Iconography, but to name them the German Fathers of Botany is superlative ; for it will have to be admitted that the mere publish- ing of plates of plants, with names of said plants and their uses, is not in itself the setting forth of any scientific principles beyond the few taxonomic ideas which the mere grouping of the plates may chance to indicate. What are plant picture-books for? In the case of the authors of them, they may be the refuge of those who can not describe, or, with such as can describe, they are a condescension to such as can not read; also to others who are 1 Plin., Hist. Nat., Book xxv, ch. 2; see also Meyer, Geschichte, vol. i, 250. The names of the ancient painters were Cratevas, Dionysius, and Metrodorus. 2 A celebrated Greek manuscript of the Materia Medico, of Dioscorides, known as the Codex Anicics Juliana, in which each plant is represented by a painting of natural size. The manuscript dates from the sixth century and was done at Constantinople. It has long been in the Imperial Library at Vienna. The whole has lately been reproduced photographically. The title page of the published work has the following: " Dioscurides. Codex Aniciae Julianas picturis illustratus, nunc Vindo- bonensis Med. Gr. I. photographice editus. Moderante J. Karabacek.

By the large picture-books of Brunfels and of Fuchs all sorts and conditions of men, lettered and illiterate, could identify some hundreds of useful plants ; a thing which never had happened in the world before that day. For this they deserve only praise. Nevertheless, had no books of botany been issued in the sixteenth century essentially different from those of the two authors named, it is difficult to see how botany could have progressed a single stage within that century. In the works of Tragus and of Valerius Cordus we have books in character essentially different from those of the two aforenamed. Both these were deeply interested in plants of all kinds ; were given to examining their organs minutely and marking the behavior of certain growths at different stages, and all this before ever having thought of writing books thereon. Also when they betook themselves to writing it was without any purpose of calling upon artists to make pictures remedying the defects of their descriptions. They were under the inspiration of a new idea in botany, namely, that plants might be so described as to be identifiable by description. Galen's dream about a kind of apostolic succession of living teachers, one generation of whom should forever teach the next to know the medicinal plants by their right names1 — all that had proven a very idle dream. Thirteen changeful, turbulent centuries had now passed since Galen. The succession had been obsolete a thousand years, and the world botanical was far at sea as to the true identity of many important plants. There must be descriptions; and they must be better than those handed down from ancient times. I should not venture to credit the erratic and garrulous Tragus with having known the history of botany so well, or having planned the opening of a new era in descriptive botany. We shall probably see, by the perusal of his book, that what he achieved here, and it was not a little, was but the spontaneous outcome of his admiring curiosity about plant structures. On Cordus' part, it is un- mistakable, there is the deliberate plan of creating a new phy- tography. Therefore, and by a study of the men and their books, I think we shall perceive that in the Germany of the first half of the sixteenth century, there were two fathers of plant iconography and two fathers of descriptive botany. 1 See page 165 preceding. CHAPTER V OTHO BRUNFELSIUS, 1464-1534 FIRST in point of time among the German botanical reformers of the sixteenth century, Brunfels is also easily first in rank respecting those educational and literary qualifications which go to the making of what one calls a scholarly book. In this particular his one botanical treatise, the Herbarum Vivas I cones, is peerless among the several books of botany that appeared in middle Europe within the first half of the sixteenth century. Others produced more and better botany; but there are marks of a dignified and conserv- ative erudition that are characteristically Brunfels' own. Life. His career was a long one, at least for a consumptive,1 and was singularly varied. One need not here analyze the motive of that countryman of Brunfels who pretended that the man's professional life might be summed up in one sentmce like the following: "At first a schoolmaster at Strassburg, then a physician at Berne." 2 This would be good language in which to epitomize the professional life of one who had been at the early outset a school- master, after that a university graduate in medicine, and then a practitioner. Such would be the natural interpretation of a sentence like that quoted; and the trouble with this pretended epitome is, that it leaves completely out of view Brunfels' occupations during the first fifty years of his life, revealing only the last twenty; for certain it seems to be, that when in default of other means of a livelihood he opened at Strassburg a school for boys, he was well past fifty years of age; also that when at the University of Basle he won the degree of Doctor of Medicine, he was sixty-five. In the history of botany Brunfels will hold in the future, as he has done in the past, a somewhat distinguished place among the notabilities belonging to his century; and we must review, as well 1 Brunfels died of consumption at Berne, Switzerland, probably at the age of about seventy years. a Sprengel, Hist. Rei Herb., vol. i, p. 311. 169 170 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 as at the distance of four hundred years we may, the incidents that had to do with the moulding of the youth, and helped to establish the character of the man. The birthplace of Otto Brunfels was Mayence, or Mainz. The family had taken its name from Castle Brunsfels1 not far from Mainz where the earlier ancestry of the botanist had lived. At Mainz, John Brunsfels, the father, was in the business of a cooper; appears to have been in comfortable if not affluent circumstances; was well known and much respected as a man of character and high integrity; also, as we learn by his opposition to young Otto's plans, a man with a will and purposes of his own; qualities inherited by the son, as we shall see. Otto was the only son, and entertained the thought of devoting himself to the service of the Church. At that time Martin Luther was yet unborn and all Germany was Catholic.2 A Catholic father of that period, if rich or well to do, would have been a marvel of pious unworldliness, if he had been willing that his only son should become a clergyman; for that would mean the immediate extinction of his own branch of an ancestral line. This father of young Otto Brunfels was resolute and persist- ent in his opposition to the son's wish; and naturally so; and this must have continued until the son was of legal age; for at last, hope- less of otherwise attaining to the priesthood, he left home and became a novice in the Carthusian monastery that was in his native town. This he would not have been permitted to do had he been a mere youth, unless the father had given consent. Meyer's inference that Brunfels remained but three or four years an inmate of the monastery 3 proceeded from several misunderstand- ings, one of which was that the man had not been born until a little before the year 1500. But there is now good authority for our accepting 1464 as the year of the botanist's nativity; so that in 1500 he was already thirty-six years old. Then, since to assume a part in the new Lutheran movement was the object of his secret flight from the house of the Carthusians, and that movement was hardly well under way before 1517, it becomes highly probable that the man was fifty-three years of age when, renouncing monasticism and giving his learning and talents to the support of Luther's cause, he took up the sojourn at Strassburg. He betook himself i Brunsfels, rather than Brunfels, was the family name. In some of our author's earlier works he wrote it Brunsfelsius; but later he appears to have changed it to Brunfelsius. » Otto Brunfels was born in 1464, Martin Luther in 1483. 3 Geschichte der Botanik, vol. iv, p. 296. LANDMARKS OF BOTANICAL HISTORY — GREENE 171 to school teaching only after his voice had failed him, so that he could no longer preach. Here again the historian Meyer draws an inference. It is this, that his school must have been a financial success, because at the end of nine years at teaching he had saved money enough to pay the expenses of his degree at the University of Basle. Without doubting the financial success of Brunfels' school it is next to certain that he realized a much more considerable income from the sale of his rather voluminous Protestant theological writings; for these included, besides learned commentaries on certain books of Scripture, pamphlets for popular reading, and a catechism for children. There is a long list of them in Conrad Gesner's Biblio- theca Universalis. Altogether his two vocations of teacher and theological author must have yielded him a very fair income during these first nine years at Strassburg; for he was able to give employment to the best engraver of Strassburg, Hans Weydiz (Latinized Guiditius) , who did the engraving of the I cones, and is a man of distinction in the history of wood engraving. It must have been after having taken his degree in medicine, and within two or three years from the time of his death, that Brunfels made a journey from Strassburg to Hornbach for the purpose of personally urging Jerome Bock (Tragus) to write a book of botany for German readers. For the record of this visit history is indebted to Tragus himself. In the thirteenth chapter of his preface to the Stirpium Historia he says: 'When information about the labors and the journeyings which I had undergone in behalf of plants had in some way been conveyed to the most learned Otto Brunfels of pious memory, he himself came journeying all the way from Strassburg to Hornbach, that he might see my gardens and collections. These things pleased him so much that from that day forward he ceased not to exhort, as did also others by letter, that I would reduce all this matter to order, and give it to the German public." Not one of even the compatriot German historians of botany, in so far as I am aware, has set before us this evidence that it was to Brunfels' personal influence over Tragus that the writing and publishing of Tragus' work was due. How much botany owes to Tragus' unusual powers of observation and description we shall learn later; for the half of that story has never yet been told. It is well worth noting that this visit to Tragus, with its fruitful consequences, was the last service which Brunfels rendered to botany. The visit must have been made as late as the year 1532; for not until that year was Tragus settled at Hornbach; and in the 172 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 next year Brunfels, now newly-appointed physician to the city of Berne, removed thither; where also after only a year and a half of service he died in 1534. After having ceased from theological authorship, and subse- quently to his having taken a degree in medicine, Brunfels pub- lished several medical works; but both theology and medicine appear to have forgotten his name. In the history of botany only is he immortal; and this because he was intensely a lover of nature and of plants. His book gives proof of this, although the figures are the best part of it. It was because his love of plants could not tolerate the absurd pictures then common, that he resolved to produce something in that line true to nature, despite the cost; for the employing of the best artist of his time can not have been less than very expensive to him, and there may have been no clear prospect of any return, even of that which the plates cost him. Indeed no one can assert that there ever was any. But here was devotion to an ideal; a love of plants that was bent upon procuring faithful representations of them in books. And so a well marked epoch in the study of the plant world dates from Brunfels and the year 1530. To the botanical memory of this ex-Carthusian, the Franciscan monk Charles Plumier dedicated the genus BRUNFELSIA in the year Phytography. If by a man's phytography is meant his manner of describing plants, that is his word-picturing of them, it cannot be said of Brunfels that he has any; and Julius von Sachs was never farther from writing history than when he set this man forth as among those who "went straight to nature, and described the wild plants growing around them." 1 Brunfels publicly disclaims all purpose of writing verbal descriptions of any plants whatever, and in the following terms: " In this whole work I have no other end in view than that of giving a prop to fallen botany; to bring back to life a science almost extinct. And because this has seemed to me to be in no other way possible than by thrusting aside all the old herbals, and publishing new and really life-like engravings, and along with them accurate descriptions extracted from ancient and trustworthy authors, I have attempted both; using the greatest care and pains that both should be faithfully done."2 His meaning as to phytography is plain. He will describe 1 Sachs, Geschichte der Botanik, p. 4. * Epistle Dedicatory, to the Senate of Strassburg, second page. LANDMARKS OF BOTANICAL HISTORY — GREENE 173 nothing anew. He will ignore the contents of wretched mediaeval herbals like the Hortus Sanitatis. He will reproduce the standard descriptions of classic Greek and Roman authors. For an example, take his presentation of the two water lilies, the white-flowered kind and the yellow. He figures them admirably, and, not having a word of his own to add to that knowledge of them which has been the common property of botanists for a thousand years and more, he supplements the two plates by three folio pages of quotations about them, taken from a list of eleven of the most approved botanical authors, ancient, mediaeval, and contemporary. Here is the list: Theophrastus Serapion Dioscorides Simon Januensis Plinius Rases Apuleius Joannes Vigonius Georgius Valla Hieronymus Herbarius Avicenna And what is true as to his presentation of the water lilies holds good in the case of almost every other genus that he takes up . Rarely does he append to such a succession of quoted paragraphs a few remarks of his own; and these always indicated as his by the special caption, " Sententia nostra," or " Sententia Othonis;" nor are such original paragraphs really of the nature of descriptions. They usually express some opinion as to the identity of the plant in question; have reference to the correct application of a classic plant name. As to phytography, therefore, the Brunfelsian vol- umes are a treasury of select quotations from a long line of books many of which are now seldom seen. But there are no new descrip- tions in his volumes ; and it may be doubted whether upon the whole he directly advanced the art of plant description by a syllable. It is no impeachment of his erudition to question that he had the ability to describe plants well. There is evidence that he had not the faculty of mentally imaging an unknown plant from its de- scription; and the ability to describe, and that of making effective use of a description are twin accomp ishments, if indeed they be not almost one and the same, so that he who has the one has also the other. Certain it is that Brunfels read and studied here and there a classic plant description to little purpose. Bringing together in one chapter the classic descriptions of Aristolochia, the figures by which he illustrates the genus are Corydalis bulbosa and C. Halleri. So gross an error explains tself in this way. The aristolochias were of southern Europe and not found in Germany. Here, however , 174 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 the roots of the fumariaceous perennials, not so unlike those of the principal aristolochia, had usurped in medicine both their place and their name. Brunfels, though professedly reforming German pharmacy by the correcting of just such blunders, did not detect this one Yet the very descriptions of aristolochia which he re- prints from Dioscorides and Pliny must have shown, had he really read them, that these things could not be aristolochias. Other such errors also remained undiscovered by him, and as inexcusably ; so that when his countryman and contemporary Fuchs remarked that in Brunfels the descriptions and the plates accompanying them are not in all cases at agreement,1 he was passing but a gentle criticism on his neighbor's phytographical shortcomings. Anthology. I have met with no evidence that during the fifteen centuries intervening between Dioscorides and Brunfels there had been any progress made in the knowledge and understanding of floral structures. There were several of Brunfels' younger con- temporaries who, after the year 1530, added somewhat to anthology; but the time was yet more than two generations distant when the science of the flower was to become so far developed as to begin happily to revolutionize plant classification. There is no sign in Brunfels that such a day is near its dawning. In his attempts to range plants in groups he is no more influenced by considerations of floral structure than were the medical botanists of remote anti- quity; even less so than Dioscorides, who, as we shall see, could not abide the placement of the bilabiate-flowered dead nettles in the same genus with real nettles, but segregated them, on account of their two-lipped corollas, and assigned them a new generic name of their own, and framed to express the peculiarity of their flowers. It is possible to rate the Brunfelsian anthology as more antiquated and imperfect than that of Dioscorides; for he of the sixteenth cen- tury less openly recognizes as generically distinct the Galeopsis and Lamium "nettles" and the proper Urtica2; and if he figures the thistles, the anthemideous composites, the principal borragineous plants, the bulk of the labiates, and some other such, each as a group by itself, it is done without any particular reference to floral structure, at least on Brunfels' part; for in all these instances he is but continuing groupings which the ancients themselves had indi- cated as being natural, and had well established. Taxonomy. Brunfels adopts without hesitancy the ancient pri- mary classification of growths as herbaceous and woody. When, « Epistle Dedicatory, in Fuchsius Hist. Stirpium. 2 Herbarum Vivas Icones, vol. i, pp. 151-154. LANDMARKS OF BOTANICAL HISTORY — GREENE 175 however, it comes to that apparently quite as ancient division of the vegetal kingdom into things cultivated and things wild, he de- liberately ignores it. His first three plates represent three most common and homely wayside weeds, members of the genus Plantago; and thenceforward throughout his volumes he deals much more extensively with wild plants than with the domesticated. Now this eliminating of the distinction referred to is not to be at- tributed to any following of the suggestions of Hippon, who some two thousand years before had declared plants wild and domesticated to be all of one lineage. There is no intimation that Brunfels had made tests, and proven out of the book of nature that this old-time grouping must be abandoned. The thought had come to him solely as a deduction from theological premises. The polytheistic ancients had held that the different alliances of cultivated plants and trees were each the creation of some beneficent particular divinity; and that the less useful or the altogether useless had hardly been created at all. The theology which Brunfels accepted, and, as a profession, taught, was monotheistic. One Divinity had made all the plants that are — the wayside weeds, the homely remedial herbs, as well as the beautiful things of the field, the garden, and the orchard. Such doctrine of the equality of all plants as to one divine origin finds expression in the last one of Brunfels' several prefaces, which contains a prayer, after which one reads his apology for giving to those common, lowly, and weedy things, the plantains, the foremost place in his system of botany. ' They are the very commonest of plants," he says, " and are known to everybody; and being both lowly and also singularly useful, they are most apt to recall to mind the thought of God, whose way it is to work wonders through means that are usually accounted insignificant, passing by such as make more display, and which men therefore hold in more esteem." l This is even showing a preference for wild growths be- fore those that have undergone domestication ; a kind of preference that has been felt by the great majority of philosophic botanists from Brunfels' time to ours; and by virtue of his being the first propagandist of this new idea he sets up another landmark in the history of botany. This idea of the equal genetic dignity of all plants seems to have come to Brunfels as a deduction from a theologic principle, rather than inductively from the study of nature; but whence he derived it signifies nothing to the disparagement of the idea itself; especially now, after all the world has come to concede its truthfulness. But 1 Herbarwn Vivae Icones, vol. i, p. 22. 176 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 it was not at once approved in Brunfels' time. There were learned men among his contemporaries who were at first startled by, and then made light of his having brought forward some of the most plebeian and beggarly roadside pe'sts, and introduced them as upon an equality into the company of the nobler growths of the fields and meadows, and of the vegetable and drug gardens. Among the more serious faults that his contemporary Fuchsius found with Brunfels' work, one was 'That he sometimes takes for subjects the most common weeds." l By at least one other item of his method, over and above this of ignoring the old distinction between things as domesticated and wild, does Brunfels commend himself as a believer in some kind of a natural classification. He declines to adopt anything like an alphabetic sequence of genera; a kind of arrangement which was adhered to by several of his noted botanical contemporaries, as we shall see. He prefers freedom to express, if but tacitly, some ideas of a more rational grouping, such as the alphabetic succession of names almost wholly precludes; and, with the medical botanist, that arrangement may be most convenient, if not even in a sense natural, in which plants, whether alike or unlike as to morphology, are held in juxtaposition by agreement as to what are taken to be their medicinal virtues. For an example of this kind of classifying carried to an extreme, take his two genera of liverworts, Hepatica and Jecoraria. The former is that anemoneous herb that has retained in later times the name Hepatica; the other is the common Marchantia polymorpha, a cryptogam. The two are figured and described on opposite pages, and their medicinal uses are said to be the same.2 It may be noted that each bears alike, even in our time, thecommon name of liverwort. Before Brunfels Hepatica usually meant the plant Marchantia, which was also called Jecoraria, and the restriction of the name Hepatica to the genus of anemone allies, and of Jecoraria to the lichenoid hepatic, seems to date from Brunfels, and was a distinctly taxonomic movement on his part; as if his judgment had been that types so very unlike morphologically ought not to be treated of under one and the same generic name. Because of their having been employed interchangeably in medicine, under the common designation of Verbena, our medical botanist figures and discusses, one next after the other, Verbena officinalis and Senecio vulgaris.3 Ths botanist of a later time will 1 Fuchsius, Hist. Stirp. in Epistola Nuncupatoria. 2 Herb. Viv. Icon., vol. i, pp. 190, 191. 3 Ibid., pp. 119-123. LANDMARKS OF BOTANICAL HISTORY — GREENE 177 see no likeness or other sign of true affinity between these; and it is very probable that Brunfels himself realized how very distinct they are when considered from the morphological rather than the remedial point of view; for when he formally designated one of them Verbena mas and the other Verbena f&mina it is beyond question that he was purposely indicating the morphological dis- tinctions between them; quite as he had done in assigning to those two morphologically dissimilar liverworts each a generic name of its own. And according to the usage of Brunfels' time, as well as for two centuries later, binary generic names like Verbena mascula and Verbena jcemina were thought as suitable, and were as freely made and admitted, as those of one word only. Of such attempted improvements in classification by appeal to considerations of morphology, one may come to a fuller appreciation by looking into Brunfels' way of presenting those many herbs which, in his time, had long been reputed to be good vulneraries, and had therefore passed under the medico-generic name of Consolida, with which Symphytum, Sanicula, Vulneraria, and Solldago were synonymous, each such name indicative of the property which these plants all had, or were believed to have, of promoting the closing-up and healing of cuts and wounds. Here is a partial list of these plants under their mediaeval names, with their equiva- lents in modern nomenclature: Mediaeval Modern Consolida major Symphytum officinale Consolida media Ajuga reptans Consolida minor Sanicula Europaea Consolida petraea Coris Monspeliensis Consolida regalis Delphinium consolida Consolida rubea Tormentilla erecta One thus gains an idea of how great a diversity of plants passed with mediaeval pharmacists and physicians under the generic name Consolida. And the list must now be given again, that the Brun- felsian taxonomic betterment of it may as readily be seen: Mediaeval Brunfelsian Consolida major Consolida major Consolida media Consolida media Consolida minor Diapensia Consolida petraea Symphyton petraeum Consolida regalis Consolida regalis Consolida rubea Tormentilla 178 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 5 4. One observes that out of the six Consolida names, three have been eliminated, and others brought forward to take their places. I say brought forward; for neither Diapensia, nor Symphyton petrceum nor Tormentilla is coined and proposed as new by Brunfels. He picked them up every one out of the ancient and mediaeval synonymy of the vulnerary herbs; from which also it will appear that other men who lived and wrote botany in times long forgotten — but the history of which times must none the less some day be written — thought as Brunfels did, that plants totally unlike in appearance, i.e., morphologically very different, ought to be invested with names more than partially different, even when as to qualities and uses they were very similar. And these group names established upon the merely remedial virtues of things visibly most dissimilar must have been misleading and confusing in the extreme. It seems as if Brunfels realized this, and intended to suggest improvement when he set aside three out of the six Consolida genus names and wrote others in place of them. It is as if he had thought it out, that since the different kinds of plants can only be well distinguished and scientifically grouped through attending to their morphology, it is not well that they should bear names that point to their qualities rather than to their forms. Therefore, in the interests of a more sure identification of important plants, as well as at the same time encouraging the appeal to morphologic marks in classifying, it would be a good thing to at least place a check upon this multitudinous repetition of pharmaco-generic names, the first half of which is the same for a half-dozen very dissimilar genera. If it be asked why he did not, while he was about it, proceed to the suppression of as many as five out of the six Consolida genus names — leaving perhaps one of the genera to bear the simple name Consolida — the right answer will seem to be that Brunfels was not of the temperament of the taxonomic revolutionist but only a reformer, and disposed to be somewhat conservative even as a reformer ; between which character and that of the bold iconoclastic revolutionist there are differences. Entirely consistent with his aversion for genera made up of plants qualitatively alike but morphologically unlike, is Brunfels' approval and adoption of some in which the species are qualitatively unlike, and at agreement morphologically. Such a genus as this is that which he fully illustrates under the classic name of Urtica,1 which in the botany of to-day comprises only the true » Herb. Viv. Icon., vol. i, pp. 151-157. LANDMARKS OF BOTANICAL HISTORY — GREENE 179 nettles. The specific constituents of his Urtica seem to be Urtica dioica, Lamium maculatum,1 Galeopsis Tetrahit, Urtica urens, and this, too, is the order in which they succeed one another in the book; first a real nettle, then two so-called dead nettles, the line closing with a second true nettle; a genus composed of two nettles, and two or three members of the very different family of the Labiatse. And this, as intimated above, is a genus not qualitatively but morphologically constituted; a fact easily demonstrable when it is remembered that Brunfels had no anthology; that the flowers of plants not only were not at all understood by him, but were the least and the last parts of them to receive any consideration. So long as two or three herbs were alike as to roots, stems, and leaves, they might easily be designated by the same common, i.e., generic, name. Forgetting, then, all anthologic differences between nettle and dead nettle, note how remarkably they are at agreement. The roots in all are small, fibrous, and not deep-seated. The stems of all are upright, almost or quite without a branch, con- spicuously quadrangular, and the leaves they bear are opposite. 'The leaves in all are short-stalked, their blades of the same ovate or oval outline, serrate as to their margins, and are of much the same texture as well as form. The seeds in all — for though anciently flowers were neglected, seeds never were — the seeds were black, and were always clustered together in the axils of the leaves all up and down the stem. All these quite marked characteristics of all their vegetative organs Urtica and Lamium and Galeopsis have in common. Since the thought is one far from being familiar to the botanical mind of the present, it must here again be insisted on, that the grouping together of several plants upon vegetative characters only, but under a generic name, is as exactly of the nature of a generic concept as that group which is rested on characters of flower and fruit only. By either method a genus may be circumscribed which shall be unnatural ; and the idea is equally the idea of a genus in either case. I do not see what chapters of any history of botanical science should be more profoundly significant, or of a more general interest, than those touching upon the development of men's ideas of a plant genus ; for the idea of the genus seems to be first and last the type- ' But this one not figured, though by implication included, as quoted from Hermolaus Barbaras by Brunfels, on page 154. Z8o SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 idea, if one may intelligibly so speak, of taxonomy. It was because this seemed to be true, that in our Introductory on the Philosophy of Botanical History, the earliest available expressions of such idea by even the primitive and the unlettered were dwelt upon somewhat at length; and for the same reason, one desires to examine with the utmost care leading expressions of the idea of a generic group as they occur in this almost the earliest propagandist of what has slowly de- veloped into the thing known as modern botany. Brunfels was of thoroughly well educated mind, even a profound scholar, also natur- ally endowed with a keen insight into the beauties and the harmonies of plant life and form. On all these accounts it would be exceedingly interesting, if it were possible, to know just what his own opinion really was as to the philosophic tenability of such a genus as this which we have been inspecting; a genus Urtica, by name, but made up of species some of them urtical, but as many others labiate. If he has any taxonomic opinion different from that which, in as far as we have proceeded, he seems to have expressed, we shall be likely to find, the evidence of it, if there be any, by reading as it were between the lines; for even a botanical genius, if writing as Brunfels professes to write, in the interests of medical botany only, inditing a work the readers and students of which are to be the physicians and the pharmacists, must not yield to every impulse he may feel to improve taxonomy; for such improvement commonly involves changes in nomenclature, and there is nothing of which the druggist, or other plant industrialist, is more intolerant than changes in names of his commodities. The opinion, if Brunfels held it, that nettles proper and labiate- flowered nettles are generically distinct, was not original with him. We observe that Dioscorides as long ago as the first cen- tury of our era segregated the dead nettle as a genus, and under a name which pointed to the character of its flower, the name Galeopsis; and this proposition had evidently been acceded to by some of the mediaeval Latin botanists, who, instead of the Greek yaXioipig, had employed such Latin equivalents as Urtica mortua, Urtica inersand Urtica labeo, the last a most significant appellation, "nettle with a lip," evidently taking cognizance of the floral character, while the other two refer merely to the lack of stinging hairs. Now this mediaeval synonymy of the plants is perfectly familiar to Brunfels. He formally quotes every item of it; and his approval of Galeopsis * as a proper genus comes out plainly enough, 1 In modern botany the genus is written Galeopsis. Dioscorides (Book x, ch. 80) wrote it Galiopsis, as did also Brunfels. LANDMARKS OF BOTANICAL HISTORY — GREENE l8l at least to the careful reader, and on this wise. In reproducing what Dioscorides had said about the labiate nettles he does it under the following caption: " De GALIOPSI simili Urticis herba, DIOSCORIDES." 1 Of such a caption the English version is, "Con- cerning GALIOPSIS of Dioscorides, an herb resembling the nettles." Of course, that which resembles another thing is not that other thing which it resembles; and nothing that was ever printed in a book is plainer than that this author did not regard Galiopsis as congeneric with Urtica. When in his Icones he sandwiches the dead nettle in between two real nettles, and when as a heading to his Chapter XXIII., in which both kinds are discussed, he places that simple " DE URTICIS," he is purposely adapting himself to the understanding of the half -taught root and herb dealers, and the untaught old women, who call them all nettles indiscriminately. In a word, Brunfels is a man of some learning and insight in matters botanical, and also a man of discreet conservatism ; holding it un- wise to lay too openly before the general public every advanced taxonomic view that is his own. In his indubitable though dissembled accepting of Galiopsis as distinct from the nettles he cannot but have been impressed by the fact that Dioscorides in making the segregation had done so in deference to its flowers, which he described as being " slender and purple"; and it may or may not have been in deference to similarity in floral structure that closely appended to the Urtica- Galiopsis series comes an unbroken line of three other galeate- flowered labiate types. If, however, this be an example of guidance by anthology to the recognition of affinity, still it is a guide which Brunfels is as far as possible from following steadily. The flowers of orchidaceons plants have as much agreement in character as have those of labiates; but when he comes to the grouping of what are known to us as the orchid genera we find that all those which have two or three large tuberiform roots are gathered into one place by themselves,2 while their merely fibrous-rooted kindred form a group quite apart from these,3 various wholly unrelated types intervening between the two orchid groups. This is all. quite after the method of antiquity; the method of those who, heedless of flowers, to the knowledge of which they had not advanced, concluded things to be allied because they were alike as to roots, and, it may be, as to stem and foliage also. 1 Herb.

The group is Brunfels Modern Scrophularia major Scrophularia nodosa Scrophularia media Sedum Telephium Ficaria Ficaria ranunculoides The point that is of special interest here is, that for the third member of the group Brunfels rejects that which was one of its common mediaeval names, that is, Scrophularia minor; though more anciently, even with Dioscorides, it was called Chelidonium minus. What he did with this third plant of the list seems to at- test that there was in him, botanically, as there was ecclesiastically, something of the spirit of the revolutionist, or reformer. If there had not been, he would have been almost sure to have called this ranunculeous herb by one or other of its ancient and mediaeval names ralher than startle the herbalists and pharmacists of his time by that new name, Ficaria, for a type so long known under very different appellations. We shall also, I think, miss a part of what was in his mind, if we do not read here the expression of an objection on his part against the old way of naming and grouping of plants conformably to their medical qualities rather than according to their morphology. All three of the plants had been called kinds of Scrophularia, because they were believed to be efficacious against ;crofula; and there is with me no doubt that Brunfels in dis- placing one of the old Scrophularia names by the new generic name Ficaria is to be understood as mildly protesting against qualita- tive criteria of plant affinities, and affirming the need of appealing to the morphologic. We were observing above how Brunfels might be said to have limited his group of the orchids to such genera of them as have a certain kind of underground organ; that he excluded from the group such as have only fibrous roots, himself all the while oblivious — as all the world before him always had been — of the flowers by the structure of which all stand at agreement. Let us now observe him locating as far away from each other two groups of genera known to us as borragineous plants. In this instance he does not separate on ground of differences as to roots, or form of leaves, but of pubescence only, that is, over and above certain qualities common to all. Upon such principles are Echium, Cynoglossum, LANDMARKS OF BOTANICAL HISTORY — GREENE 183 and Borrago made to form a group of genera.1 We of to-day, after four centuries of taxonomic progress, concede that Brunfels was correct in apprehending a very intimate consanguinity between the three. But we hold them in juxtaposition on quite other grounds than those which had weight in the early sixteenth century. We judge them near allies because the plan of their flowers, and the common characteristics of their fruits are the same. With Brunfels the flower was so a' most wholly unknown that no such thing as the plan of a flower had been thought of. And, viewed superficially— the only view that had yet been taken of flowers at all, — they were very notably dissimilar. The corollas of the genera are of remark- ably distinct types, that of Echium being narrowly tubiform below, with an irregular almost bilabiate limb ; that of Cynoglossum is short- salverform, perfectly regular; that of Borrago broadly and flatly star-shaped. Few families of plants present three genera so unlike as to the cut of their respective corollas as these three. We there- fore seem to infer to a certainty that in collocating these three generic types, he had had the utmost regard to their likeness as to roots, stems, foliage, and especially to that armature of harsh somewhat stinging bristles wherewith all three alike defend them- selves; and that in the process of his reasoning the corolla, i.e., the "flower," was not at all considered. And, as if to place this beyond dispute, two other borragineous types are relegated to another part of the book. One is a Cynoglossum, the other a Myosotis.2 Both differ from the other group in that they show no trace of the stinging-bristly or any other rough indument. They are almost silkily soft-hairy. Had he not held such differences to be most significant, taxonomically, it is impossible to see why he separated so widely these two groups of what we of to-day understand to be near allies. If one is to follow the progress of plant taxonomy from the year 1530 forward, it will be needful to bear in mind such things as Brunfels' failure to apprehend the consanguinity of all the borragineous genera that he knew; as well as to note, if perchance one may discover the reason, why he failed. Then afterwards it must be observed how those who came after him, one after another and little by little, brought the other genera of such a family into a continuous sequence ; also all the while attending to — even carefully noting — the development of new principles, whatever they may have been, in accordance with which the better taxonomy of more i Herb. Viv. Icon., vo!. i, pp. 111-113. *Ibid., 175-177. 184 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 recent centuries has been attained to. Thus may we learn, and thus only, the lesson of the modern development of the very old idea of plant families. Nomenclature. All plant names are names of groups; and to group things together under a common name is to classify. No- menclature and classification are therefore so intimately connected that neither topic can be fully discussed apart from some consider- ation of the other. They can not be completely divorced ; and so it was inevitable that something in relation to Brunfels as nomencla- tor should be brought out under the heading of taxonomy. It will be useful, however, to epitomize his work as nomenclator, and particularly since he now and then evinces a disposition to amend and improve upon ancient and mediaeval names and name-making methods; or, it might perhaps better be said, a disposition to return from mediaeval to ancient methods; for what I have in mind is something like a distinction which, in a general way, holds between what may be termed the ancient and the mediaeval plant naming. It is, however, not much more than a difference between the genius of the Greek language and that of the Latin as to manner of fram- ing distinctive names for things. In Greek the noun and adjective readily combine to form a single word, such word beginning with the adjective part and ending with the noun; whereas in Latin noun and adjective are kept as distinct words, even with the noun rather than the adjective standing first. To make this as plain as possible let us use a few examples : Greek Latin Leucoion Viola alba Melanion Viola nigra Chrysion Viola aurea Herpetion Viola repens Chelidonion Viola hirundinaria By many scores of such one-worded Greek plant names which by translation into Latin become binaries, there is revealed one of the misfortunes under which mediaeval and early renaissance botany labored everywhere — for mediaeval botany was Latin botany — that of having in its employment hundreds of binary names, some of which were of specific import, while as many more were but the names of monotypic genera. The continual perplexities involved in this phase of nomenclature seem to have exercised the mind of Brunfels to a degree, so that LANDMARKS OF BOTANICAL HISTORY — GREENE 185 he made bold to displace here and there some binary generic name, substituting one of a single word. A few examples of such action on his part were brought forward under the heading of his taxonomy . A more considerable exemplification of this practice is given below, in a selection made from the first volume of the Viva I cones: Early binary generic names Fumus terras Fumaria herba . Ferraria major Consolida minor Testiculus canis Testiculus vulpis Lingua bubula Sacra herba Verbenaca supina Cincinnalis herba Lacryma Junonis Herba sanguinalis Sanguis Mercurii Mustelse sanguis Crista gallinacea Trixago minor Quercula minor Scrophularia minor Chelidonium minus Herba Apollinaris Faba suilla Brunfelsian substitutes Capnos Sanicula Satirion = Borrago Verbena Chamaedrys Ficaria Hyoscyamus The credit of having reformed the nomenclature of genera by the exclusion of names made up of two distinct words has been given to Linnaeus, who, in the year 1751, is thought first to have laid down such a principle.1 But the actual reform had been quietly inaug- urated by Brunfels two hundred and twenty years before Linnasus came forward with his Philosophia Botanica. Sprengel, the one nineteenth century author of a Genera Planta- rum who has observed the law of priority in the crediting of generic names, ascribes to Brunfels the authorship of the following: Ammi Fragaria Pyrola Calendula Linaria Sanicula i Nomina generica ex duobus vocabulis integris, ac distinctis facta, e Republica Botanica releganda sunt." Linn., Philosophia Botanica, Art. 242. l86 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 Carthamus Melissa Spinacia Castanea Parietaria Scrophularia Euphrasia Potentilla Valeriana To this list of fifteen, credited to this author by Sprengel, I find two more to be added, namely Hepatica and Ficaria. Sprengel's reason for not taking them into the reckoning was simply this, that he did not admit the types as worthy of generic rank, but held with Linnaeus that the former was but an Anemone and the latter a Ranunculus. Now when Sprengel and other advocates of priority credit such genera to Brunfels, it is not to be understood as their meaning that in his book these types are for the first time named and defined. The truth is, that all of them had been known before Brunfels, and some of them had been much written about, under different names. For a heading to each chapter in which a genus is discussed, Brunfels selects, out of the several names current for that genus, the one that pleases him best; and, by virtue of the great prestige which his book obtained, the plant names in it were continued in use by other authors. Therefore they who credit Sanicula, Potentilla, Fragaria or Hepatica to Brunfels affirm no more than this, that each such name, as the fixed appellation of a certain generic type, is traceable back to Brunfels. In his researches upon native German plants he came to know here and there a type which, after the most diligent comparison with all the classical plant descriptions, he felt certain had not been known to the ancients, neither been described by any one. They were new generic types; and to such he never assigns any name at all, other than that by which it is known to German peasants. There is beautifully figured in one place a flowering plant of Carda- mine pratensis.1 Above the figure the German name Gauchbluem is inscribed; beneath it the statement in Latin that the plant was unknown to the ancients, though common enough in Germany, and native. One page is occupied by a most accurate and life-like representation of Anemone nemorosa, with the legend: " A wildwood herb, the name of which is unknown."2 Nor is there any other mention of the plant ; not so much as a record of its being known by a vernacular name. This is doubtless the earliest publication of the Wood Anemone. Out of such namelessly figured types there might here be gathered surprising items of plant history. For one instance: any one 1 Herb. Viv. Icon., vol. i, p. 218. J Ibid, vol. ii, p. 80. LANDMARKS OF BOTANICAL HISTORY — GREENE 187 informed as to how familiarly hundreds of useful plants were known two thousand years before Brunfels would expect to find so common and important a plant as Trifolium repens among that number. Nevertheless, it is one of the things which Brunfels presents as new to botanists.1 He says it is well dispersed through- out Germany, chiefly in meadows, and is known to the common people by the name of Weiss Fleischbluem ; also that his engraver brought him the plant under that name. That Old German name of the plant, and Brunfels' brief remark upon it, both printed on the plate page, seem to constitute the earliest publication of Trifolium repens.2 Both the botanist and the artist seem to have agreed in the opinion — a purely philosophic one — that no little weed was beneath botanical notice, and between them they have given us the beginning of the history of Draba verna. The plant is elegantly figured under the vernacular designation of Gensbluem; but not another word is said about it.3 It is, however, the first record, and a perfectly definite record, of an interesting though diminutive type; one that within the last century has been much discussed by very able botanists who have investigated it morpho- logically, taxonomically, and even as to its rightful name; and that Old German popular name Gensbluem — in later German Gansblum — has proven a somewhat fateful appellation. More than two centuries after Brunfels had printed it, Michel Adanson pro- posed its adoption as being by right of priority the lawful generic name .^ For two reasons, not calling for mention here, Adanson 's movement failed of any public approval. Yet once again, in the end of the nineteenth century, Otto Kuntze renewed he Adan- sonian proposition;5 but the attempt to reinstate Gansblum was again fruitless, at least as to gaining public approval. It was not a Latin-made name. Probably it did not occur to Brunfels' mind that a little weed, of no use in medicine or any art, needed to be dignified by any other name at all than that by which the country people of Germany knew it. To the nomenclature of species it is evident Brunfels gave no thought ; nor was there any reason why he should have given it any attention. Most of the genera, with him as with the botanists of antiquity, were monotypic, and the generic name was all that was 1 Herb. Viv. Icon., vol. ii, p. 55. 2 The botanists of remote antiquity knew but one plant which they called Trifolium. It figures in modern nomenclature as Psoralea bituminosa. 3 Herb. Viv. Icon., vol. ii, p. 34. 4 Adanson, Families des Plantes, vol. ii, p. 420 (1763). 5 Kuntze, Revisio Generum, vol. i, p. 29 (1891). l88 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL 54 needed. There was not the shadow of a reason for appending a second name; and he, no more than hundreds of botanical writers before his day, ever thought of such a thing. Sometimes when there are one or more notable modifications of a type — varieties or species of it — the original goes by the generic name only, while the others have each its own cognomen. Of this sort is his nomenclature of three buttercups which he figures and gives account of.1 In the nomenclature of to-day they are (i) Ranunculus acris, (2) its double- flowered garden variety, and (3) Ranunculus bulbosus. The generic name which Brunfels adopts is Pes coruinus, i.e., Crowfoot, turned into Latin. With him the first species is simply Crowfoot, its variety of the gardens is Full-flowered Crowfoot, the third plant is Lesser Crowfoot. This early practice of leaving the one original representative of a genus without any cognomen, even after said genus has ceased to be monotypic, is a practice doubly suggestive in relation to the philosophy of nomenclature ; for, in the first place it plainly reveals the antiquity of the idea of generic types, and emphasizes it. In the second place, the failing to assign a cognomen to the type species entails a difficulty; becomes a possible source of ambiguity and perplexity; for, Pes coruinus being mentioned, the question may chance to be asked: Which one of the three? That question is virtually a demand, and a most reasonable one, that the type species have also its particular cognomen. That botanists of fifteen centuries anterior to Brunfels had seen this to be desirable, one may infer from the nomenclature of Plantago. Two species of this genus were known to Pliny; and he had a specific cognomen for the type species as well as for the other. They were Plantago major and Plantago minor; and Brunfels follows Pliny in this. His type species is not simply Plantago; it is P. major, which name, as well as P. minor, the German father duly credits to the Latin author of the olden time. He uses, then, a specific name for the orig- inal representative of a genus when there is classic authority for so doing; but I have not observed him taking the initiative in this course by actually himself assigning to the type species of any genus a cognomen. These paragraphs on Brunfels as nomenclator ought not to be concluded without our having taken a briefly comprehensive survey of his principles. These principles, such as he was more or less ruled by, will be all the more suggestive to us from the very fact that he did not professedly have any; for doubtless he had never 1 Herb. Viv. Icon., vol. i, pp. 143-150. LANDMARKS OF BOTANICAL HISTORY — GREENE 189 so much as heard, or even thought the phrase "botanical nomen- clature." The laws governing the naming of plants were not different from those observed in the naming of other things. All that we may gather by observing his procedure along these lines may be the course which a cultivated and philosophic mind, unhampered by prejudices, will naturally take. But such a study will be well worth while ; because one does not often meet with an author who so nearly antedates all our stereotyped conventionalities, and takes his own course so little influenced by traditions and prejudices. Without having enunciated one of them, he seems to have been more or less under the guidance of principles like the following : 1. That for the science of botany there is an initial book; that is the Historia Plantarum of Theophrastus of Eresus. He quotes that work constantly, but never, I think, any earlier book or author. Others of Brunfels' time and a little later we shall find citing Moses, Solomon, and other Hebrew writers as if these had been botanists; but not so Brunfels, who, notwithstanding his train- ing in theology, and the distinction he had won as a Biblical scholar and commentator, does not intimate that he has found botany in Holy Scripture, and never cites an author who antedates Theo- phrastus. It will not, however, follow that he must adopt The- phrastan generic names in such wise as to make that author's monumental work the point of departure for nomenclature. The existence of an historically first book of botanical science is one thing. The having a starting point for an universal nomenclature of botany is quite another; and the two are both logically separ- able and historically separate. Brunfels was well informed about the historic beginnings of botany; but the idea of an universal system of nomenclature for groups of plants had not in his day been conceived. 2. Brunfels writes in Latin. The text of his book is for those who know Latin, and, knowing it, know things by their Latin names. The writer is under the necessity of using the Latin names of plants rather than those by which the same plants are known in Greek or Hebrew, Arabic or Persian. If a man pretending to write in Latin about animals should write hippos instead of equus, or alopex in place of vulpes, he would stultify himself; would be writing unintelligibly, absurdly, and ridiculously. It is not imagin- able that Brunfels, in a Latin book of botany, should have done so insanely as to write drys instead of quercus, or kittos in place of hedera, ion rather than viola, or arnoglossa rather than plantago. SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 Nevertheless he might have done so and most reasonably; indeed he must have done so, had the ideas of universality and priority in nomenclature been conceived and approved by him; because botany is of Greek rather than Latin origin, and so the Greek names of plants happen to be older than the Latin names. It was needful here to take a survey of the whole situation; for from Brunfels forward we must be looking for adumbrations of any of those prin- ciples which in our time have come to rule — or misrule — biologic nomenclature. 3. Even as a Latin writer, and using none but Latin generic names as headings for his chapters, Brunfels does not pay respect to priority. He readily adopts, out of several Latin names, an- cient and mediaeval, not the oldest, but the one that best suits his own purpose or fancy. From before the Christian era until six or seven centuries after it the water lilies had been known as the genus Nymphcea. Then from the eighth century forward to the thirteenth and later the Arabic name Nenuphar had usurped its place in Latin botany generally. Brunfels adopts Nenuphar and writes Nymph&a down among the synonyms; this manifestly for the reason that most of the botanists and druggists of his own time knew the plants as Nenuphar and would be disturbed if he should restore the classic name. Here, then, we have 4. The principle that the name by which a genus is known to most of one's contemporaries is the one to be taken up, there being no other objection against the name. 5. That a later name consisting of one word only is commonly permitted by Brunfels to supplant a very ancient one made up of two words has been already quite clearly demonstrated. 6. A species name, or cognomen, is not assigned the type which alone represents its genus. 7. While plainly favoring the selection of the best of several names as the one to be perpetuated, Brunfels, as if realizing the inconvenience of having many synonyms, is moved to use the greatest care and caution against creating them; that is, against creating Latin synonyms. This is well shown by his great aversion to assigning Latin names to types which to him appear undescribed. He publishes freely the engravings of such, but is careful to label them with no other than the German vernacular names. I have not found him once deviating from this very conservative practice. And, under his beautiful plate of Pulsatilla, in a long paragraph he explains why he holds to such a course. In none of the authors whom he has been able carefully to study has he found any descrip- LANDMARKS OP BOTANICAL HISTORY —GREENE 191 tion of this sort of plant. It may have been named and described somewhere nevertheless. He is resolved to print the figure, and leave it to others who have more leisure than he, to study it in the light of all descriptions to them accessible.1 Meanwhile the thing may be known by one or other of those German names by which the common people know it. 8. The student of botanical nomenclature should here note well the distinction which Brunfels tacitly makes between the Latin names used by Latin botanical writers, and those invented in their mother tongue by the common people. It is plain that with him they have not the same status. The vernacular name cannot figure among the Latin synonyms. It is upon no equality with them. His action and his words together bring it out clearly that, in his mind, there is a botanical nomenclature, and synchronously with it a kind of plant naming that is not valid scientifically. The botanists of antiquity had not, and hardly could have had this thought. Is the expression of it new with Brunfels ? He who is to answer this question must first learn pre-Brunfelsian and mediaeval botany. The prevalence of that opinion is long since become universal, despite its having been ably disputed two centuries after Brunfels. It will be important to the history of nomenclature that one trace its progress from Brunfels forward. 9. In respect to the nomenclature of species it should be observed that what is often spoken of now as the phrase name, or more unadvisedly the "polynomial," and commonly attributed to all botanists preceding Linnaeus, is a thing unknown to Brunfels. In genera of several species I have not found him using in a single in- stance any name that is more than binary. Where there are three words to a name the first two are the generic name. 1 Herb. Viv. Icon., vol. i, p. 217. CHAPTER VI LEONHARDUS FUCHSIUS, 1501-1566 AN early and a clear vindication to Brunfelsius of the honor of having made an epoch in the history of botanical iconography is the fact that his Herbarum Viva Icones inspired a younger coun- tryman of his to embark at once in a still larger enterprise of the same kind; this with the manifest purpose of outdoing the originator of the movement. Brunfelsius and Fuchsius were alike in that they were college bred Germans and university graduates; their early and also their later academic and professional training having been acquired in Catholic schools, and mostly while they themselves were yet Catholics ; and they were witnesses of the beginnings of the Lutheran movement, and both became partisans of the Augustin- ian; Brunfels with voice and pen actively and zealously furthering the movement, and Fuchs so expressly in sympathy with it as to have forfeited thereby the professorial chair with which his alma mater had early honored him. Both were regularly graduated medical practitioners, and both eminently successful, even famous, as physicians; though this good fortune came to the elder of the two only very late in life, and after he had abandoned theology and polemics. Life. Fuchsius was a native of Memmingen, Bavaria. The father died when the child was in his fifth or sixth year. The small boy must have been precociously intelligent. The care and cost which the widowed mother bestowed on his education, and the academic honors conferred on him in boyhood, youth, and very early manhood attest this. At the age of ten he was sent away to a noted school at Heilbronn, at eleven to Erfurth where, after a year and a half of very special and zealous devotion to what were already his favorite studies, the ancient languages, the university conferred on him the degree of Bachelor of Philosophy; this before he had completed the thirteenth year of his age. During a year and a half, and that while he was somewhere between the ages of 192 LANDMARKS OF BOTANICAL HISTORY GREENE 193 fourteen and eighteen years, he was master of a private school in his native town; to the success of which undertaking on the part of one who was a mere boy in years, a precociously large stature, quiet seriousness of mind, and a manly dignity of bearing are said to have contributed.1 At the age of eighteen he again left home, and this time to enter the university at Ingolstadt, where at first he applied himself to advanced classical studies, and two years later obtained the degree of Master of Philosophy. Entering at once upon the study of medicine at the same institution he won the doctorate in the year 1524, at the age of twenty-three. He under- took to establish himself in the practice of medicine at Munich ; but after a residence there of some two years, within which time he had married, he was called to the Professorship of Medicine at Ingolstadt. Here another and more honorable place was soon tendered him, and he became physician to the Margrave George of Brandenburg. During an outbreak, at Anspach, the residence of this prince, of that very fatal epidemic which one reads of as the plague, Fuchsius acquired reputation by the success that at- tended his treatment of the disease. He remained physician to George of Brandenburg some five years, and it was during this period that his career as an author began. He published a Com- pend of Medicine, then a translation from the Greek of one of the books of Hippocrates. He was now called a second time to the Chair of Medicine at Ingolstadt. The call was accepted; but again the stay was short. This university still remained one of the strong- holds of the old faith. Doctor Fuchsius let fall expressions of sympathy with Luther's movement. Within less than a year he withdrew, returned to Anspach, where the Margrave George gave him welcome, and reappointed him body physician. The next year witnessed another outbreak of the plague, and this time Doctor Fuchsius with his wife and children fled the place. In the year 1535 he received a call to the Chair of Medicine in the then newly established Protestant university of Tubingen. Here he remained to the end of his life, that is, for thirty-one years ; and they appear to have been years of the most arduous and unremitting activity. His lectures on medicine were extraordinarily popular, and the intervals between lectures were occupied by the duties of the practitioner. He declined one offer of a professorship in the celebrated University of Pisa, and another to the office of Physician to the King of Denmark.2 1 Melchior Adam, Vitas Germanorum Medicorum. J Meyer, Geschichte der Botanik, vol. iv, p. 311. SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 As to when, and amid what surroundings Fuchsius became in- terested in botany, I have met with no record. It may, however, safely be assumed that no passion for nature study, or for plants in particular, was congenital with him. There is internal evidence in his book that as a botanist he was not born but made. The curricula of the schools of medicine at that period offered the possi- bilities, at least, of the making of botanists. The medicines in use were still chiefly plant products, either native or imported from Asia. The names of them were plant names. Each was the sub- ject of a chapter in the standard books of the materia medica. Those books were all ancient, and had been written by the Greeks, Hippocrates, Theophrastus, Dioscorides, Galenos. Their chapters were the texts on which university professors of medicine lectured to their students; and the identification of the plants more or less succinctly described in those classic chapters was a part of the regular work. It was the examination of plants in the light of what purported to be the original and authentic descriptions of them. Critical work of this kind may be done by a student as a piece of drudgery, or it may become an inspiration. To those not too sluggish it must have been stimulating to be able to demon- strate by Greek texts ten or fifteen centuries old that the vendors of drugs were selling important medicines under wrong names; that what they sold under the Greek name aristolochia, for example, was not in the least like what the great Greek physicians had used under that name either morphologically or qualitatively. And if such questions took them to the drug gardens, or led them afield into wild places in search of medicinal plants in their fresh and growing condition, all this would tend to the fuller development and the deepening of a sincere interest in botany. There is every reason for believing that Fuchsius' interest in botany was* thus awakened. His earliest botanical publication fully substantiates this view. It was issued by Brunfels as an ap- pendix to the second volume of his Icones in 1531, that is, ten or eleven years earlier than the appearing of his principal botanical work. Its title translated is Leonard Fucks' Notes on certain Herbs and Simples not yet rightly understood by the Physicians.^ It consists of thirty-fottr long chapters upon more than as many plants and plant products then in use ; dealing mainly with the right application of ancient names; often quoting the language of authors whom he 1 " Leonard!

LANDMARKS OF BOTANICAL HISTORY — GREENE 195 charges with having brought in this confusion under which the pharmacy of his time is laboring, and denouncing the errors of such authors with scathing sarcasms. The aim of the essay is the elimination of gross errors from the pharmacopeia, and all the subjects are plants that have been in use for ages. Nothing new is added; neither is there any trace of the philosophic investigation of the plant world as such; or the revelation of any interest in plant life and form in themselves considered. But this is Fuchsius' juvenile botanical production. Will there be awakened within him later an interest in plants as plants rather than as drugs? There is no evidence that such an awakening ever came ; or that any considerable part of his work with plants had other than utilitarian ends primarily in view. In the last chapter of this earliest piece of his botanical writing he expresses the design of going through the whole of Greek and Latin botany, correcting errors and giving the right identification of everything, after the method exemplified in the treatise he is now concluding; even adding that he has been urged to do this by those fully convinced of the great need of such a work. But this promise remained un- fulfilled. The twofold duties incident to a professor's chair and an extensive medical practice claimed his energies, and the twofold emoluments enabled him to undertake a line of botanical work — botanical recreation, rather — which it is improbable he ever would have thought of but for the great success which had promptly attended the publication of Brunfels' I cones. He employed two painters, and also the best engraver in Strassburg,1 and set them to work figuring plants. Thus within seven or eight years after the appearing of Brunfels' work Fuchsius had ready for the press his great volume of the Historia Stirpium; though it was not is- sued from the press until some four years later, that is, in 1542. Its success seems to have been speedily assured, and was really wonderful. To a generation that had been accustomed to such books as the Hortus Sanitatis, filled with the most wretched carica- tures of plants in place of true representations of them, this great book by Fuchsius must have appeared as nothing less than luxur- ious; and the epoch which, ten years earlier, Brunfels had introduced by his 135 good illustrations of as many plants, was strongly ac- centuated by the appearing of this new volume with upwards of 500 large plates more than equaling, on the average, those of Brunfels. 1 The portraits of these artists, with their names, Heinrich Fullmaurer, Albert Meyer, and Veit Rudolf Speckle, are appended to the first edition of the Historia Stirpium. 196 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 Within a year, or a little more, there was issued an edition in German, this augmented by six more plates. Then in 1545 there came out, as if in condescension to the class of the unlettered, an inexpensive edition of the plates only, and this was so successful that a second issue was made in that same year; both these were in octavo. After that there were not a few small-sized and cheap editions brought out, with Latin text, but with figures so greatly reduced in size as to be of little use. With these, however, Fuchsius had nothing to do. During the long tenure of the professorship at Tubingen, which covered nearly half his lifetime, there was no return to that critical work upon the history of medicinal plants with which he had inaugurated his career as botanical author; nor were there any more than casual questionings of nature even as to the affinities of plants. But the botanical artists were kept at work. To have more plants figured, and to formulate a page of text to accompany each plate, gave him pleasant respite from professional work, and promised greater fame and fortune. Before his death he had ready for the press the plates and descriptive texts of fifteen hun- dred plants; a work which, if it had been printed, would have made three folio volumes as large as the Historia Stirpium. But when all was done, no publisher could be found who would undertake the issuing of so vast a work without the advance of a considerable sum of money. This the author would not — perhaps could not — accede to, and the manuscript remained unpublished.1 In the original Latin edition of 1542, the Introductory Epistle, addressed to the Margrave of Brandenburg, is a document deserving fuller notice than can here be given it. It is a rather lengthy discourse, but withal instructive as to the condition of botany at the time, and exceedingly well written; amounting to something like an abstract of the history of medical botany from the earliest times down to his own date. As a piece of writing it reveals in its author general abilities altogether superior to what I can not but consider the mediocrity of his gifts as a botanist. It is in these introductoiy pages that he earns for himself the praise of being a fair and equitable judge and critic of the work of others, of whatever race, religion, or nationality.2 At a time when it was usual in Germany to depreciate, if not to denounce, all French and Italian efforts to restore botany, Fuchsius proclaims it that they are all inexpressibly indebted to such great scholars as Hermolaus 1 Meyer, Geschichte der Botanik, vol. iv, p. 313. 1 "^quissimus majorum suorum judex." Sprengel, Hist., vol. i, p. 324. LANDMARKS OF BOTANICAL HISTORY — GREENE 197 Barbarus, Marcellus Virgilius, Ruellius, and others who, through corrected texts and Latin versions of the Greek fathers, first placed them at the service of the botanists of every country. He takes pains to defend them one and all against aspersions that have been cast upon their works by men incompetent to criticise them, and recommends the study of them to all. When, in their turn, his own countrymen and contemporaries, Brunfelsius, Cordus, Tragus, come up for mention, it is always most respectful and even honorable mention; and this despite the fact that among them there is a rival or two whom he fears, and has good reason to fear, still is he solicitous to be just to each, and to speak out the favorable things concerning their work which may be said. A representation which he makes in this preface, of the low estate into which the pharmacy of his time had fallen, I must in substance reproduce. "The times once were when not only great philosophers and poets but kings and princes both investigated plants, and favored others so occupied. But in our day even the physicians are so much averse to that kind of study that you will hardly find one among a hundred of them who has correct knowledge of even a very few kinds. They appear to think that this kind of information does not belong to their profession, and to judge tha^; it would be condescending from their proper dignity to entertain doubts about the accuracy and trustworthiness of those who buy and sell such things. And so it comes to pass that the druggists • — God knows that they themselves are for the most part an illiterate set — leave all this to the foolish and superstitious old women who gather herbs and roots. Error is therefore heaped on error, and will be so long as the identification of vegetable medicines is left to rustic and vulgar ignorance." The superb South American genus FUCHSIA was dedicated to this, the second father of plant iconography, by Plumier in the year 1703. Vegetative Organography. Fuchsius has a very instructive and useful introductory chapter which he styles " An Explanation of Difficult Terms. " From the historian's point of view this will be re- garded as most valuable. It is the earliest vocabulary of botanic terms that I have met with thus far; and no historian that I know of has made mention of it. One gathers from this vocabulary good information of progress gained — and also of retrogressions made — in descriptive and organologic botany in the seventeen centuries and more between Theophrastus and Fuchsius. True to his title, our author omits all easy and familiar terms ; does not define anew Ip8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 the root, the stem, the leaf, the flower. By this we know that he has nothing to add to the ancient and classic diagnoses of these organs. He does, however, define a bulb. " Bulbs are roots that are round and tunicated; such are those of the hyacinth, asphodel and colchicum. " There is here a retrogression from Theophras- tus, who doubted that the tunicated mass ought to be considered a root, and who also mentioned that the tuft of fibres descending into the ground from underneath are undoubted roots. Neither of these considerations affects the mind of stolid Fuchsius. Bulbs are roots that are rounded and tunicated. I do not recall having met with an earlier use of the word tunicated as describing certain bulbs. It is very apt, and has now long been everywhere in use as definitive of one kind of bulbs. With him. however, the em- ployment of it is unfortunate ; for it makes the tunicated structure to be characteristic of all bulbs, which is a bad mistake, as ex- cluding the scaly kind, like that of lilies, from the category of bulbs; for not the crudest morphologist could call a scale a tunic. And Fuchsius proves his definition fallacious by stating, when he comes to the figuring and describing of the true lilies, that they have bulbs.1 His referring to the asphodel as an example of a bulbous plant will be misunderstood. He has not at all in mind that plant which in later times has been identified as the famed asphodel of antiquity, the underground parts of which have nothing that is in the nature of a bulb of any kind. That which Fuchsius believes to be the asphodel, and figures for it, is a lily, and its scaly bulb is well shown.2 If his third familiar example, colchicum, illustrates to us what we distinguish now as a corm, it is at least fibrous-coated on the outside, and would therefore answer at least to the letter of his diagnosis of a bulb. There is one term in use in the sixteenth century in connection with certain bulbous plants which has not survived; that is, the neck (cervix). Fuchsius defines the cervix as "an elongated and cylindric body intervening between the summit of a bulb and the tuft of leaves, and has the appearance of a neck." From its position, and its external appearance as cylindric and supporting leaves in onions, leeks, daffodils, and their kindred, one might have expected to find it designated as a stem. That it was not, is a circumstance that must convince us of two things: first, that Theophrastus' immortal definition of a stem as made up of bark, wood, and pith, was a part^of the very alphabet of botany in Fuch- 1 Hist. Stirp., p. 366. 2 Ibid., p. 115. LANDMARKS OF BOTANICAL HISTORY — GREENE 199 sius' time as it is in ours; and second, that the stem-like cylinder surmounting onion, leek, and daffodil bulbs must have been ex- amined in cross section and found completely destitute of every characteristic of stems in general; discovered to be made up of nothing else but the compacted bases of the leaves themselves. It looked much like a stem. Investigation proved it wanting every claim to that title; and they named it cervix, the "neck" of a grow- ing bulb. The word was not destined to a permanent place in the vocabulary of the science. When at length it came to be seen that the bulb itself, as well as the cervix, was also but a mass of leaf-bases, and therefore no root at all, the term lost its particular significancy and disappeared. And this very fact of the invention of a new word that seemed to be called for, and its later passing into desuetude, is an interesting kind of episode in the history of morphology, and well merits notice in a place like this. We shall meet with other instances. Respecting that more marked phase of underground stem, the rhizome, or rootstock, Fuchsius appears quite securely to rest in a position which Theophrastus had held with wavering. Fuchsius denominates them all radices geniculata . The Greek had realized that they have rather too much in common with stems. In his treatment of stems in general, one observes in Fuchsius some divergencies from, even here and there some little advance ment beyond, the status of these things in the minds of the ancient authors. The word culmus, modified from the Greek calamos, is his term for the stems of grass-like plants. The first and largest divisions of tree trunks are denominated brachia, arms, though not unless such diverge from one another rather strongly, suggesting, as he says, arms of the human body when extended. Others had always noted what they called the knots, or nodes, of stems. Fuch- sius uses, and even defines, the good term internodium, internode; though I much doubt his having invented it. He also observes in trees and shrubs the occasional development of long and vigorous- shoots from trunks and main stems ; points at which branching is unusual if not abnormal. He names such shoots adnates. Botanjr still recognizes this class, and knows them as adventitious shoots,, from adventitiously formed buds One reads in this author and in others of his time of such things as the al(E of stems. The usual meaning of alae is wings, as of a bird; but in ancient Latin the term also meant the armpits; and quite like this is the sixteenth-century use of it in botany. Fuchsiu? defines the alas of stems as being a kind of sinuses from which new 200 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 growth proceeds; they are the axils of modern terminology. It is also here that I meet with scape as a botanic term; and the application is just that now in use, designating an elongated peduncle arising from under the ground; though neither Fuchsius nor his contemporaries so understood it. They regarded it as a true stem without nodes. But Fuchsius' " scapus" was not at once adopted ; until long after his time it was usually denominated a stylus. Two of the several modes of leaf arrangement are named and denned in this vocabulary, the decussate and the verticillate ; but there is yet no one word in use by which to distinguish leaves as opposite. A phrase is required to express that. Any leaf margin that is evenly indented is described as crenate, or as serrate, quite indiscriminately, the terms being treated as synonymous; but if serratures be quite deep and close, as in the nettles, the leaf is fimbriate. Pediculus and petiolus, i.e., peduncle and petiole, are employed as indiscriminately, either one applying to leaf-stalk or to flower-stalk. The word stipula also makes its appearance in Fuchsius' vocabulary, but with nothing like its meaning in more recent botany. His definition proves it to have been in his mind merely a special name for the peculiar leaf of grass-like plants, not a part of such leaf, but the whole of it.1 It is a definite proposal that, since the stems of grains and grasses have the special name of culm, the leaves of the same class of plants ought not to be called leaves, but should have their own special designation — should be called stipules; and this is perfectly logical and consistent; for the leaves that grow on culms are quite as unlike all other leaves as culms are unlike other sorts of stems. It will be recalled that Theophrastus had named this entire group the Calamophylli in allusion to the remarkable characteristics of the foliage. But Fuch- sius does not seem to have met with success in this endeavor to have grain leaves and grass leaves become known by the name of stipules; and, more than two centuries later, Linnaeus picked up the old term siipula and applied it anew, and with perfect success. Fuchsius tried also to invest the compound leaf with a name of its own, as a thing too different from the simple leaf. The dis- tinction itself, as we know, was perfectly and for all time made by Theophrastus, who discovered things and left them nameless. The German father would have the compound leaf called a frons, i.e., frond, thus restricting the other Latin word folium to the simple leaf and the individual leaflet of the compound. But this also fell short » "Stipulse sunt folia culmum ambientia. " Fuchs. LANDMARKS OF BOTANICAL HISTORY — GREENE 2O I of general adoption; and long after Fuchsius, frond came into use as designating the peculiar foliage of ferns. It must be said of Fuchsius' application of frond that it was the more correct; for frons with the old Latins meant the leaves of trees, or even leafy twigs of trees, such as, anterior to Theophrastus, and by thousands in later times, the compound leaf was believed to be. Inflorescence. The term inflorescence of course did not appear in botany until long after Fuchsius; but the thing had been of necessity both observed and discussed. The using of words de- finitive of the various clusterings of fruits and flowers must be older than history. Perhaps few if any of those defined by the German father were newly coined, or even otherwise applied than they had been in far earlier times. But here in the Historia Stirpium we have a goodly number of them brought together, along with not indefinite statements of what that author understood to be their meanings. And what must vouch for the importance of this para- graph of history is the fact that not one of Fuchsius' terms relating to inflorescence bears with him the meaning which the same term has in the botany of our own time. Take the word thyrsus, which at its first origin in Greek and Latin was but a synonym of caulis, any stalk or stem; though later, and still in ancient times, it acquired a special significance; while with botanists of our time it means a particular kind of inflores- cence. There is with Fuchsius no kind of a flower clustering that is called a thyrse; yet he essays to define the term as if in the botanical terminology of his time it had gained some new shade of meaning. From his definition itself nothing of the kind is apparent ; but at definition Fuchsius is no adept ; and when he says a thyrsus is a straight wand-like or arrowy stalk he has hardly departed from the earliest of ancient definitions. But wThen we make search for his practical use of the term we find that it has with him a meaning which he had not indicated or intimated in his definition. In the description of the hyssop he uses the expression: "Flowers purplish-blue, investing the thyrses like a spike."1 Here it is plain that the thyrsus is the axis of a spicate inflorescence; that which in much later botany is become the rachis. But it is only now and then that he notes the arrangement of flowers; though the clustering of fruits is much more frequently taken into account. The term racemus occurs not infrequently; but I think only as specifying the arrangement of some berry-like kinds of fruits. The type of the raceme is the grape-cluster; but in his definition 1 Hist. Stir p., p. 840. 202 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 of racemus he says it is the fruit cluster not of the grape only, but also of the ivy and of any kind of herbs or shrubs that have bunches of berries. In practice we shall find him writing of the compactly spicate berries of the arum as forming a racemus. As with the ancients, so with Fuchsius the spike is rather more a taxonomic than morphologic term. His definition of it is the most concise of all. " A spike is that which a culm bears at its summit. ... It consists of three parts, grain, glume, and beard. A muticous spike is one that is beardless." Plainly, then, the spike with him is the peculiar inflorescence of grains and their natural allies. The typical form of a spike, that in which as in wheat and barley there is a simple rachis — thyrsus, he would have called it — up and down which the several parts are sessile, is not alone a spike. The one prerequisite of a spike is, that it shall crown the summit of, or at least be connected with, a culm. And so we find him naming as spikes the inflorescences of broom corn,1 and also of maize.2 In modern botany they are panicles. Only thus far, however, does he abide by his own diagnosis of the spike as the fruiting cluster of grass allies ; beyond this point, and lere and there, we find him overstepping the bounds which he himself has set to the application of that term. Lavandula stoechas, an aromatic shrub common in European gardens of that time, is of the family of the labiates, the flowers of which are congested within a somewhat elongated and cylindric involucre of chaffy and overlapping scales. This involucre vividly recalls the head or ear of some short-spiked kind of wheat; and Fuchsius transgresses his definition boldly enough by calling the involucre of this inflorescence a spike.3 In justice to the botanist it must, however, be admitted that he was following popular precedent. The inflorescences of not only this but a number of other labiates had long been called spikes. There is then traceable in Fuchsius a tendency toward a point that was not actually gained until more than two centuries later, of defining terms by morphologic rather than any other characteristics; of naming a raceme from its structure rather than from the fact of its bearing berries and not capsules ; and a spike not as the fructiferous terminal of a culm, but as an axis, bearing up and down its length sessile flowers or fruits, this irrespective of the family of plants in which it may occur. The panicula is almost unique among Fuchsian inflorescences in i Hist. Stir p., p. 772 ' Ibid., p. 824. *Ibid., p. 777. LANDMARKS OF BOTANICAL HISTORY — GREENE 203 that it is not made the mark of any particular taxonomic group, and is defined in quite strictly morphologic terms. As far as possible from the panicle of modern vocabularies, it consists of almost any very compact cluster that is somewhat elongated and, at the ends, well rounded. The first example given is that of the cones of spruces, which are not conical, and therefore would not have been called cones by botanists of antiquity, nor by their disciples of the sixteenth century. But it is said by our author that the Latins applied panicle mostly to such as, being of the requisite form and density, were also appendaged by some sort of coma ; and so, among the Fuchsian panicles, one finds the bristly hairy spikes of millet, and the elongated furry heads of the mouse-ear clover, otherwise called lagopus, i.e., Trifolium arvense. Also individual spikes of scirpus, eleocharis, and others of their tribe — the indi- vidual spikes, I say, and not the whole inflorescences — are panicles. The umbel, though defined morphologically as a flower and fruit- cluster constructed upon the plan of an umbrella, would never be applied to an umbel of berries. The umbels with Fuchsius are the inflorescences of the family of umbellifers, or at least of dry- fruited plants, exclusively. The flat-topped clusters of certain anthemideous composites like millefolium he speaks of as umbels; though they are not really umbels, but corymbs; a distinction that had not then been made. Anthology. In the vocabulary of Fuchsius there is vouchsafed a perfectly intelligible definition of what he calls the calyx. It is a kind of "bag within which at first the flower, and after that the seeds are enclosed." Note first of all, that such a calyx as this can be no part of a flower. It can not be determined to be a calyx until it has shown itself permanent ; until the seeds have ripened. A deciduous calyx would be a contradiction in terms. A circle of green sepals behind a flower, even though at first enclosing the "flower" does not constitute a calyx; at least if it fail to persist and to enfold the seeds after the other parts have fallen. Under this definition all mintworts and sages, the borrageworts and other syn- sepalous things have a calyx, while the poppies and the buttercups and their allies have none. The pomegranate and all pomaceous fruits are furnished with that organ; the olive and all drupe bearing trees are destitute of it. This appears to be the earlier idea of a calyx; the first movement toward the bringing in of that green-leafy circle close behind what was called the "flower," to where it should be recognized as a part of the flower. But his having technically defined the calyx does not preclude his occasional 204 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. $4 employment of the term in an untechnical sense, that is, as de- signating some other organ that happens to be shaped like a cup; thus we find him calling the lily flower a calyx,1 i.e., a chalice-shaped flower. His doctrine of the flower in general is that of Theophrastus hardly improved upon. There are two kinds, the leafy and the capillary; but both are united in, for example, the rose. The term petal is still wanting in botany. Its introduction into the vocabulary will not be proposed until two generations after Fuchsius. The foliar parts of a flower are still leaves only. Yet what is curiously interesting is, that already as the green leaf is seen to have usually that which they have called its petiolus, or pediculus, so the flower leaf is credited with having its unguis, or claw; the more or less narrowed basal part by which it is attached to its receptacle. Fuchsius defines well enough this unguis, even remarking that in the flower of a red rose this claw is white. And so the distinguishing of the two parts, blade and claw, in this organ historically antedates the naming of the whole organ as petal; and Fuchsius, so far from affirming this to be a new distinction of his own making freely attributes it to "the ancients." In this Fuchsian vocabulary occurs what is perhaps the earliest botanical definition of stamens. There is so much of history in it that one must reproduce it as literally as may be. " Stamens are those apexes that come forth from the middle of a flower-cup ; and are so called because they rise up like filaments out of the inmost bosom of the flower." As a definition this is illogical and bungling; for both the anthers and the filaments are separately called the stamens; not by any means the two parts that go to the making up of stamens ; either one alone is stamen according to his absurd statement. In the first clause the anthers, apices, are the stamens; in the second, the filaments are the stamens. That what he de- nominates apices are the anthers is clear as day from his description of the flower of the common white lily, where he remarks that in this the apices are yellow ; for no other parts of the lily blossom are yellow but the anthers.3 The term filamenta by its very mean- ing applies to no other organs but the filaments and styles. Let us note here that there is yet no description of a stamen. The author neither thinks nor speaks of the thing but in the plural. What he > Hist. Stirp., p. 363. 2 " Stamina sunt qui in medio calycis erumpunt apices; sic dicta, quod veluti filamenta ab intimo floris sinu prosiliant." Fuchs, in the vocabulary. J Hist. Stirp., p. 363. LANDMARKS OF BOTANICAL HISTORY — GREENE 20$ has seen, and what all the botanical authors before him had seen, is a tuft of delicate things standing up from the midst of the circle of colored flower leaves. The ancients had written of them as •flocci, or as capillamenta, still only in the plural. No one had ever looked into the individuality of one of those flocci or capillamenta. To have done that would have been to lead the way to the discovery that the members of the filamentose tuft are not all alike; that at least the one central member — if not the whole central membership of the tuft — is different from those that stand between them and the circumference of the flower. There would soon have been two kinds of Stamens to describe if one stamen had been defined, because of those — the styles and their stigmas — which would not have answered to the definition. Now Fuchsius in practice writes of these tufted things in the middle of a flower as the apices. This is a distinct departure from the terminology of antiquity, and is withal a departure in the right direction; for the ancients had seen and written of flocci, capillamenta, and the German had seen — perhaps by some unknown mediaeval botanist had been taught to see — the little knots that surmount the outer set of the flocci, and from these little apical knots the whole stamen-tuft had been named anew, "apices." This term, whensoever it made its appearance, came in like a kind of prophecy that the terminal knots were one day to be received as the only essential parts of the tuft. One would willingly concede to Fuchsius the invention of this term which shows that anthers are being noticed; but he was in no sense a botanical discoverer, and he availed himself of many an old book and manuscript of which we have no knowledge. For the staminate tassels of hazel, walnut, and oak trees he has also now a name; whereas the ancients seem to have had none. But he has no more idea what these tassels are for than the ancients had; though he ventures the guess that they are instead of flowers; thereby proving that he had never seen the pistillate or real flowers of any of them. He calls the pendents nucamenta, nut-tassels, and describes them in language borrowed from Theophrastus who, as we have been learning, had a much better knowledge of nut-tree flowers then Fuchsius ever attained to. Fruit and Seed. The Greek ^philosopher's comprehensive and classic definition of a fruit is either unknown to Fuchsius, or else he purposely condescends to the popular notion; for he says that a fruit is something made up of flesh and seeds. This is quite in keeping with his definition of a raceme as being a cluster of fruits. 206 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 i.e., fleshy fruits, rather than a particular mode of clustering in both flowers and fruits. Seed coverings other than fleshy are dis- posed of by him under two or three distinctive terms. There is the silique, the vasculum and the capitt as well as its diminutive, the capitulum. The legumes he says are siliques, and yet many other herbaceous plants and even shrubs bear siliques; and we infer his silique to be any kind of an elongated and two-valved pod. He ventures upon no definition of what he calls vascula, beyond this, that they are the coverings of seeds. His account of head and capitulum is, that they apply to any well rounded and solidified part of a plant, whether basal or terminal. An onion-bulb, resting wholly above ground and therefore not a root, is a head, a caput; and so is the head of a cabbage, and also the round indurated capsule of a poppy. If he knew anything of Theophrastus' technical de- finition of a fruit as composed of pericarp and seed, he does not appear to me to have made use of it, or of the term pericarp. The seed is not defined in our author's vocabulary, or even mentioned there otherwise than incidentally. Phytography. There has already been cited this opinion of phytography from Brunfelsius,1 that the best way to reform and improve upon mediaeval plant description would be to restore word for word the descriptions of the ancients. At a later time it was thought — and the thought was carried into action — that the only possibility of improvement in phytography lay in wholly disregard- ing the classic texts, and writing all plant diagnoses anew. Such a proposal as this last would have filled either Brunfelsius or Fuchsius with amazement; and also not unreasonably, for neither of them had in view the reformation of botany in general. Both were aiming at the correction and improvement of that which we of to- day would speak of as the botanical part of the pharmacopeia. They were interested in phytography, because it is one of the necessi- ties of medical botany. The most trying part of their work was that of the identification of ancient remedies; and their only clues to the identity of any of them were in the ancient descriptions. We have followed Brunfelsius in his giving, for some plant newly figured, page after page of different descriptions literally quoted from those whom he regards as standard authors, not willing to divert the attention of the student by a single line of his own; willing that they who study his book shall judge for themselves whether what he has figured under a given Theophrastan, or Dioscoridean, or Plinian name has been rightly identified. 1 See page 172 preceding. LANDMARKS OF BOTANICAL HISTORY — GREENE 207 The ideal of Brunfelsius is high. His book is for scholars; but Fuchsius plans to be more popular. He will publish twice as many plates as the former had done, and for the sake of economy must reduce the number of pages of printed matter. The average is not much more than a half-page to a plate; yet the descriptive part of Fuchsius' volume is not in all respects insignificant when compared with that of Brunfelsius. There is a falling off in the bulk of interesting and useful matter; but some good phytographic distinctions are made which do not appear in Brunfelsius. Every chapter of Fuchsius is divided into separate and separately named paragraphs, of which always the first, headed Nomina, is devoted to the name and synonymy of the genus, and con'ains nothing else. In the case of every monotypic genus the second paragraph is headed Forma. In this we read always the morpho- logic marks of this type ; at least such of them as Fuchsius can copy out of standard authors. When, however, a generic type is known to be made up of two or more species or varieties, then this morpho- logic paragraph is not second in order but third; the second being now given to the naming and defining of the species or varieties; and this occasional second paragraph is always under the caption Genera. In an earlier chapter an explanation has been given of the primitive use of the term genus, and its plural genera, as meaning nothing more nor less than the kind or kinds of a thing.1 It is plain that Fuchsius' "genera" are the species and varieties, while under Forma he gives the morphology of the genus as a whole. The placing of the descriptions of species and varieties first, and that of the genus next below is illogical in the extreme; but there are still other intimations that a logical mind was not among the learned Fuchsius' natural endowments. But this segregating of the morphology, the ecology, and the properties of a plant, and the relegating of each to its own paragraph is definitely an improve- ment in phytography, and is perhaps an invention of his own. Taxonomy. We are learning that there was in Fuchsius nothing of the plant anatomist or physiologist, something of the organ- ologist, but that he was in no wise given to philosophizings about plant life and form in general; that he was a medical botanist, dealing with plants from the utilitarian point of view. He would not have appeared as a taxonomist had not taxonomy been in- evitable wherever more than one individual plant is treated of. Concerning the larger and more comprehensive groups, the 1 See pages 115, 1 1 6 preceding. 208 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 genera major a of the botanists of a somewhat later period , the orders or families of to-day, there is little to be read in Fuchsius; for his sequence of genera is alphabetic, a kind of arrangement which pre- cludes the grouping of genera into families. It does not, however, in any way influence the definiteness of the genera themselves, or of the species composing them. The work is divided into 343 chapters, and each chapter is devoted to one genus and no more; so that the number of genera treated of is the same as the number of the chapters. Many of the genera are represented by only a single species, many by two or three, several by four or five, and one has seven species, all described and figured. But one must not pass to the study of his genera without noting certain lapses from the alphabetic arrangement which are made in deference to what are held to be the affinities of a genus. These are not numer- ous, but they are enough to show Fuchsius as susceptible of being influenced by the idea, even in his time an old one, that some genera are interrelated. Here it must also be observed that the alphabetic order he follows is that of the Greek rather than Latin names of genera. For medical botany, all through the ages and down to Fuchsius' time, Greek rather than Latin was the preferred language of nomenclature, at least with those best educated; because all three of the most venerated authorities upon that part of botany, Hippocrates, Dioscorides, and Galenos had been Greeks and had written their treatises in Greek. Now while in his Latin text Fuchsius uses the Latin names of things, quite as he ought, the generic names heading the chapters are the Greek generic names; and the sequence is that of Greek letters of Greek names; so that the chapter on the genus of the elder trees or bushes is headed not Sambucus but Acte, and that of the plantains not Plantago but Arnoglosson. Now for a sequence of genera in a book of sixteenth-century botany, the choice of the Greek alphabetic order left its author certain liberties. All Latin names are naturally exempt from such a rule ; and there were now in Fuchsius' time not a few plants holding places in the pharmacopeia which had not been known to the Greeks of old, and which therefore had only their Latin and their vernacular appellations. Since the Latin names of these may not consistently head chapters where the headings are professedly Greek, Fuchsius is apt to use these as occasions for giving ex- pressions of opinion about natural affinity by placing them in the line of what he conceives to be their real kindred. For one instance, take his placing of Datura ^tetel, a plant then newly LANDMARKS OF BOTANICAL HISTORY — GREENE 209 introduced into Europe, where it was known only by the Italian name of Stramonia. Since it has no Greek name he locates it where he will; and we who have been taught that there was no natural classifying of plants until well toward the end of the eighteenth century may well be surprised that Fuchsius places this at the end of a line which begins with Solanum nigrum, such perfectly solana- ceous types Solanum melon gena, Phy sails somnifera, and Atropa Belladonna intervening. That very early in the sixteenth century there was already in exercise the taxonomic skill to put together as under one com- prehensive natural genus such diverse-looking consanguinities as the five plants here named is something that merits more than passing notice. It is another -of those forceful intimations that much of the botanical history we once learned must be unlearned. Let us remember that we are now at a point more than one hundred and fifty years anterior to those great lights, Morison, Ray, and Tournefort, and some two hundred anterior to Haller, Jussieu, and Adanson, to which latter trio is usually accorded all the glory of having first outlined such natural groups as this. But Fuchsius himself intimates that from very ancient times there had been a somewhat familiar knowledge of four out of these five plants, and says that both Dioscorides and Galenos had held them to be kinds of ffrpi'xvov, i.e., Solanum.1 But the referring of so marked a new type of plant as Datura to the anciently recognized group of the Solanum allies by men of the sixteenth century will hardly fail to suggest to some that there must have been, after all, some appeal to anthology. Certainly the conventional nineteenth-century botanist finds no stronger links uniting these two plants to one family than the symmetrical pentamery of the flower, coinciding with a plicate praefloration and superior ovary. It is none the less well beyond question that not a single point anthological had in- fluence in determining the affinities of Datura. The corolla has not yet, at this period obtained its name. It is still the "flower'* simply. Neither stamen nor style had been taken note of as an individual organ; much less had the two been distinguished, or the members of either set been counted. Floral symmetry was yet unnoticed; and, marked as is the aestivation, or praefloration of solanum and all its allies, the very topic of praefloration was not yet heard of in Fuchsius' time, nor did it begin to figure in taxonomy until some two centuries after his demise. According to Fuchsius, 1 Hist. Stirp., p. 691. 210 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 his best reason for locating this type in the line of the nightshades is the fact that its herbage exhales the narcotic odor characteristic of all other nightshade allies. Plant classification, then, in Fuch- sius' time has not yet emerged from the period of antiquity ; and botanists are still considering agieement among plants as to their vegetative and qualitative characteristics, giving little heed to those of flowers or fruit. And a fair measure of success not rarely attended taxonomic effort guided by these criteria. But the success, however marked in the case now in mind, was not quite complete. Capsicum is undoubtedly a solanaceous type, but this fact Fuchsius failed to apprehend; yet the failure is not unaccount- able, notwithstanding that, viewed morphologically, capsicum is much more plainly akin to nightshade than is Datura. The plant was a new one in German gardens of the sixteenth century as was also Datura. It had been as unknown to the ancient Greeks, and had no Greek name ; therefore Fuchsius could have placed it next Solan- urn. The fact is, no one had yet seen its relationship. The plant lacks the narcotic odor. Every part from leaf to seed is of a peppery odor; and this quality, amounting to a burning pungency of taste, joined to the peculiar medicinal qualities, blinded every one to that affinity for Solanum which every one now sees in Capsicum. It must not, however, be inferred that this principle of qualita- tive agreement is held an inviolable rule in this early taxonomy. "With botanists of that time, quite as with those of every later generation, the endeavors to form groups are dominated sometimes by one principle, sometimes by another. It is easy to bring forth outjrf Fuchsius instances of putting things together as of the same genus regardless of odors and flavors and of almost all other marks save those of roots and leaves and general mode of growth. Under the genus Verbena he figures two species. There is the most decep- tive likeness between the two as to roots, stems, leaves, and a slenderly spicate inflorescence of small flowers; but one of these verbenas is Verbena supina, the other is Sisymbrium L&selii; a true verbena and a crucifer made congeneric; in the Fuchsian binary nomenclature Verbena recta and Verbena supina.1 It will not be easy for the systematist of to-day to imagine so natural an alliance as that of the crucifers remaining unrecognized by those who had already recognized the solanaceas; yet as to roots, foliage, and habital characteristics the crucifers differ among themselves a hundred-fold more widely than do the solanaceae. « Hist. Stirp., pp. 59 1-593 • LANDMARKS OF BOTANICAL HISTORY — GREENE 211 Despite what we of later times perceive to be the naturalness of the cruciferous group, its recognition had to await the development of anthology; and I have met with no evidence that up to the time when the career of Fuchsius was ended there had yet lived a botanist who had known the floral structure of a crucifer. Even the Theophrastan elements of anthology seem to have been sunken in oblivion ages before the birth of Sprengel's and Meyer's and Sachs' " German Fathers of Botany," one or two of whom were to renew the investigation of floral structures; though Fuchsius was hardly one of these. The contemplation of these quaint herbalistic genera based on vegetative characters and ignoring flowers and fruits is both en- tertaining and instructive. It is as if one had discovered in these antiquated tomes a fossilized and now extinct system of plant classifying; and the reader will not fail to be interested in glancing at the outlines of other such genera. Fuchsius has one little genus for which he brings forward into print, from out an unpublished manuscript, the name Pilosella. Here is the composition of the genus : 1 Fuchsian Recent Pilosella major Hieracium Pilosella. Pilosella minor Antennaria dioica. He has tried to make one of the plants answer to the Myosotis of Dioscorides. It does not well agree, and he is confident that neither of the two was known to the ancients. Both are well known in Germany, and of repute as vulneraries, on which account he must not omit them. The German herbalists of his time know one of them by the name Pilosella. That will suffice for a formally generic name, and with it he has already headed his Chap, ccxxx. 'Two kinds of it are found, differing in nothing but the flowers. One of them has leaves that are larger, and do not lie flat upon the ground. Its flowers are yellow, and it is named Pilosella major. The other has smaller leaves that lie flat upon the ground, and purple flowers which disappear with a pappus. The Germans have for this the names Little Mousear and Rabbitsfoot. In a manuscript herbal I find these plants disposed of as Pilosella major and minor." I thus present a literal version of what our author had to relate respecting the components of this his genus Pilosella, even to the interesting admission that the whole chapter had been borrowed ' Hist. Stirp., pp. 604-607. 212 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 from an old herbal in manuscript — illustrated by drawings, no doubt — which had been available to him. Even the specific names P. major and P. minor were from said manuscript. Contemplating these two plates, whether the proposed genus consisting of a hieracium and an antennaria seem rational or absurd will depend entirely upon whether one view the types with the eye of the modern botanist, or with that of him of Fuchsius' time. The modern, taught by the traditions of not more than five or six generations of his more recent botanical ancestry, looks at the flowers only, and in consequence realizes only that the two must be regarded as of widely separate genera; for one has the flower head of a hawkweed, the other a congested bunch of cudweed heads; and as to the structure of their individual flowers they represent something like two extremes. But it will be both illogical and unfair to test the consistency of the earlier classification by pre- suming to hold it amenable to modern taxonomic principles ; though this seems to be about what the readers of old botany, and even the historians, have always hitherto been doing. The consistency of the Fuchsian Pilosella is readily seen if, blinding ourselves as he and his forbears were blind to small floral structures, we look at and compare those parts of the two plants which tbey looked upon as bearing marks of consanguinity. Both the antennaria and hieracium are small perennial herbs of one and the same mode of growth, and that mode rather exceptional. Each has its leaves most- ly in a basal tuft, and bears its flowers at the summit of scapiform stems. A number of depressed stolons leafy with a smaller foliage radiate from the base of the stem of each, so that both in the same fashion propagate vegetatively and form colonies. Add to these and other points of morphologic agreement the consideration that both were received as possessing the same remedial virtues, and we have a rational genus according to all the leading principles of sixteenth-century taxonomy. Thus comprehending the situation — realizing that these groups that look so strange and motley have not been formed at random, but rather under guidance of definite principles — every such group acquires a new and even a lively interest. Let us open the book at its initial chapter. The name of the first genus is Absinthium. Three species are described, two of them figured well. They are: Fuchsian Recent Absinthium vulgare Artemisia Absinthium. Absinthium Seriphium Sisymbrium Loeselii. LANDMARKS OF BOTANICAL HISTORY— GREENE 213 Thus a cruciferous plant, common in German vineyards and hedge- rows, is made congeneric with wormwood because it has similar foliage, and also is thought to answer to Seriphium in several other particulars. It is a good example of futile effort to identify with the Seriphium of Dioscorides a very different plant of central Europe which Dioscorides never saw, and which, by the way, if he had seen it, he would never have thought of as a kind of worm- wood; for, as we have seen, the Greek did not quite disregard floral structures, but could distinguish genera by anthologic marks.1 But Fuchsius' disregard of flowers in these generic groupings is manifest again close by Absinthium, in his Anthemis. The name of the genus and those of all three species are taken up from Dioscorides, as he says, and the following is his identification of them, the names at the right being those now in use. Fuchsian Recent Anthemis leucanthemon Matricaria chamomilla. Anthemis chrysanthemon Anthemis tinctoria. Anthemis eranthemon Delphinium Consolida. Judged by the modern and improved standards, the locating of a larkspur as congeneric with chamomile is the worst of conceivable taxonomy; and it is impossible that in this Fuchsius interpreted Dioscorides otherwise than erroneously and even almost stupidly. The Greek had habitually looked at the flowers of things, and had shown clearly a tendency to regard the forms of flowers as taxono- mically significant. Concerning Anthemis in particular he declares that the flowers in the three species differ only as to the color of the little leaves that encircle the centers of the flowers, which central part he says is yellow in them all.2 Now concerning the identity of the white-rayed and the yellow-rayed Anthemis species of Dioscor- ides there never had been any doubt; therefore as to these two Fuchsius was but reiterating the expression of a common opinion. The third member, however, that is, the purple-rayed anthemis, was problematic ; for there is not known in those regions where the ancients botanized a purple-rayed composite having the foliage of an anthemis. But there need not be; for any ranunculus- flowered or anemone-flowered branching herb, if it had the foliage of anthemis might have been relegated to that genus. It is only to the trained eye of the modern botanist that the rayed head of a 1 See page 180 preceding. 2 Dioscorides, Book iii, ch. 130. 214 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 composite and a ten-petalled flower of an anemone or a buttercup seem very unlike. By the ancients, and by everybody down to Fuchsius' time and much later they were not regarded as being different. The superficial likeness between the two is great. In either type there is a yellow center made up of little things com- pacted together, and this is encircled by rather many narrow leaves apt to be different in coloring from those of central tuft, or mat, or cone. The different constituency of those yellow centers in anthe- mis and anemone no one had yet perceived, even in Fuchsius' time. With him, as with all botanical antiquity, the yellow middle part was made up of the "stamina," the " capillamenta, " the "flocci," in anthemis as in anemone : and that the circle of colored leaves is a circle of ray-flowers in anthemis, and of petals or sepals in a*nemone and buttercup — that is a refinement anthological of which neither Dioscorides in his day, nor Fuchsius fifteen centuries later, had ever dreamed. But in the grain fields of Greece and Italy there grew in abundance one anemoneous herb with perfectly anthemideous habit and foliage, and flower leaves dark-red — easily within the wide range of the purples of the ancients. Must not this have been the Anthemis eranthemon of Dioscorides? Its modern name is Adonis cestivalis.1 Certainly this, rather than Delphinium Con- solida, is the third anthemis of the Greek physician. And the fault of Fuchsius is his utter disregard of those floral marks in respect to which the Greek had said that all three species of an- themis were at agreement; though as to mere foliage, and the annual root as well as more of growth, the larkspur-anthemis of Fuchsius answers well enough to the other kinds; and this would have been the apology for Fuchsius' erroneous determination of the plant, had he not virtually disclaimed it for himself by attributing it to some unknown earlier botanist whose anonymous manuscript has been at his disposal. In this manuscript he says, "there is an exquisite drawing of this plant, which is commonly called consolida regalis, " and then he proceeds to quote, from this unknown author, the following: " Some call the herb Monachella or else Capuciaria, doubtless in allusion to the hood of the monks, which the flower recalls. Dioscorides calls it Eranthemon, and it is one of the kinds of Anthemis, having the foliage of the chamomile, though of a darker green ; but the flower is rather like that of a violet. " 2 Evidently the author of that unpublished commentary had been i See Matthiolus, Comm. (ed. of 1565), pp. 904-906, with fine plate of Adonis, in between two plates of anthemids. ' Hist. Stir p., p. 28. LANDMARKS OF BOTANICAL HISTORY GREENE 215 too superficial in his knowledge of the wild plants of Mediterranean fields to well interpret Dioscorides. But his identification of the third anthemis appears to have suited the fancy of Fuchsius and he approved it. His former rival, Brunfelsius, a dozen years earlier had maintained that the Consolida regalis was sui generis, and did not think it had been known to any of the botanists of antiquity.1 There seems to be evidence within the book of Fuchsius itself that the work was long in preparation, and the middle and later chapters printed so much later than the earlier as to bear intimations of his mind's having changed somewhat in the direction of an ap- preciation of floral structure as having some value in the de- termining of plant relationships. While his contemporaries Brunfelsius and Tragus hesitated to distinguish generically be- tween the real nettles and the labiate-flowered dead nettles, Fuch- sius separates them widely, and under the names of Urtica and Lamium2 ; this, however, not as an original proposition, but as adopted from Dioscorides and Pliny. In his description of the genus Pisum, the garden pea, he says that its flower is shaped like a butterfly; but I do not find him using the expression in describing other plants of that family; and while this is the earliest mention of the papilionaceous corolla form that I have met with, I still think it improbable that it was original with Fuchsius. Among several new genera proposed by this author there is one, namely Digitalis, which he establishes almost upon the form of the corolla alone.3 This genus of two species, which he names re- spectively D. purpurea and D. lutea, practically concludes this volume of more than 900 pages ; and so a course that began in almost total disregard of anthological considerations, ends in the admission that floral structure may upon occasion be of such high taxonomic import as to furnish the most essential character of a genus. Con- trasted with the beginnings of the volume, this conclusion of it is taxonomically very significant; even prophetic. It forecasts the time a hundred and fifty years later when Tournefort, running to another extreme, would essay the systematization of all petaliferous plants, almost by the corolla alone. Nomenclature. All the unconventionality, simplicity, and brev- ity of a primitive and even a classic nomenclature marks the 1 Brunfelsius, vol. i, p. 84. * Urtica, Hist. Stirp. pp. 105-109, three species; Lamium, Ibid., pp. 468, 469, also three species. » Hist. Stirp., pp. 892-894 2l6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 plant-naming of Fuchsius. As already indicated he heads each chapter with the Greek name of the genus, unless perchance the plant was unknown to the Greeks and has no Greek name; then the Latin name is used. For every one the Latin and the German synonyms are given, and that in the first paragraph of the chapter, under the caption " NOMINA. " Still more carefully considering the convenience of pharmacists and the untutored collectors of simples, he causes to be printed on each plate the Latin name of the species at the lower left-hand corner, and at the right-hand corner the Ger- man. Quite as we expect to find it, we read on plates representing monotypic genera no name at all but the generic. Commonly such names consist of but one word. Such are Adiantum, Alth&a, Anethum, Asarum, Asparagus, and scores of others as familiar and as ancient. But there is also no dearth of purely generic names for monotypic genera that are of two terms. There are Acorus officinarum, Tagetes Indica, Plantago aquatica, .Aster Atticus, Barba Capri, Vitis vinifera, Vitis alba, Vitis nigra, Viola pur pur ea (= Viola), Viola alba (=Matthiola), and very many more like these. There is no ground for questioning that every one of these names is purely generic. There is no warrant for denominating so much as one of them "a pre-Linnaean binomial," that is, a name of which the first word is, in the accepted sense, generic, the second specific. Names binary, and of just this last named quality do also abound in Fuchsius ; but these now cited, and also a host of others like them, have nothing in them of the generico-specific meaning which all binaries in use to-day convey, and are understood to convey. Now that Fuchsius does not mean by Plantago aquatica any species of the genus Plantago is put beyond all doubt or cavil by the facts, first, that he takes it as the topic of a chapter apart from that in which Plantago proper is discussed1 ; and second, that the officinal, or more properly scientific (Greek) names heading the chapters are totally distinct, the one being Arnoglosson, the other Alisma. Concerning Vitis vinifera, now long in the status of a generico- specific binary, it is as readily demonstrable that with Fuchsius it is purely generic. Assuming that in primitive times the one word Vitis — in Greek a ^TteAos — was, as it now again is become, the generic name for grape-bearing shrubs, there came in later such two-worded generic names as Vitis alba, Vitis nigra, Vitis Idcea, etc., each standing for a completely and widely different genus. It is easy to see that such multiplication of generic names beginning i Plantago (of two species) is the topic of ch. xi, pp. 40, 41; Plantago aquaiica (monotypic) is of ch. xii, pp. 42, 43. LANDMARKS OF BOTANICAL HISTORY GREENE 217 with Vitis rendered it needful that the original Vitis should receive also a second and modifying term in order to avoid confusion; and thus there came into existence, and of necessity, the generic name Vitis vinifera instead of the simple and primitive Vitis. Let us see what Fuchsius' genera of which this term is a part of the name, really are : Fuchsian Recent Vitis vinifera Vitis Vitis alba Bryonia Vitis nigra Clematis Specific names, with this German father, quite as with all his forbears that I know aught about from Theophrastus forward, are strictly binary. One simple word, almost always adjective, constitutes the specific term of such binary, and is the cognomen, as some called it. It happens, indeed, with many a such binary name that it is composed of three separate words ; but that is always for the reason that the generic name is of two words. Not much less than a hundred of Linnaeus' trivial names of plants are of three distinct words; but this is because he makes the specific part of such names to consist of two words, and never the generic part. This is precisely the difference between the Fuchsian and the Lin- naean binary nomenclature; and there exists no other difference. We amend Linnaeus by connecting by a hyphen his two-worded specific names. This is done in order to preclude if possible any questioning of the fact that the two words which we have hy- phenated are to be thought of as one. It were equally in place to hyphenate the terms of Fuchsius' two-worded generic names. This done, he who ran might read the truth that all Fuchsian plant names not those of monotypic genera are as strictly binary as those of Linnaeus; with even this one difference in Fuchsius' favor, that he has no two-worded specific names. As to general principles of botanical nomenclature, those of Fuchsius seem few, and easily ascertained. Those principles appear to be convenience, etymological suitability, brevity. If all his names are binary, and, as being the mere names, hold places entirely apart and distinct from the descriptive paragraphs, as they always do, then there is not even the suggestion in Fuchs- ius of those "phrase names," so called, which became a burden upon the phytography of two centuries later ; and it may be said of his work that it is quite a model of brevity in nomenclature. Inasmuch as the Greek names of genera are older than the Latin, 2l8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 54 and he gives to them a kind of precedence, making them the head- ings of his chapters, there might arise a question whether the Greek names were preferred on account of their right of priority. But there is other evidence that the principle of priority in nomencla- ture obtained no recognition with him; was perhaps never once thought of. The standard works on the materia medica in use everywhere in Fuchsius' day had been written in Greek; which fact alone would give the highest prestige to Greek plant names. Their Latin names, needful to be used for the convenience of the many who knew Latin but not Greek, were in every way as valid as the Greek names. Both were used, chiefly as a matter of the greater convenience to readers and students as a body. That he never thought about rights of priority as worth contending for comes out as clearly as possible in his presenting a new genus with the new generic name Digitalis. :< We make use of this name, until we ourselves or some one else shall have invented a better one."1 The above remark attests its author's opinion that there could be appropriate names and inappropriate, and that names either bad, or even not very good, might well be suppressed in favor of new ones more suitable. Even the principle of convenience, which always favors the retention of an established name whether bad or good, may be overruled for the rejection of a name that is ill constructed, and the substitution of a new and better one. There is one generic name that had held good for some fifteen centuries, a Greek name too, which he declines to adopt as the heading of its chapter, evidently because etymologically distasteful to him. The name in Greek is Ocimoides, formed by the addition of aides to the generic name Ocimum. Instead of the ancient and established Ocimoides he writes for a heading to the chapter the new name Ocimastrum2; an initiative in the reform of generic nomenclature which Linnaeus two centuries later was to carry forward with universal approval. He who thinks that nomenclature, like the science itself, should be subject to advancement and improvement, must be believed to have his reasons; though Fuchsius does not appear to have declared his. One thing, however, we observe, and that is that all the names he uses have their meanings. A genus is named in allusion to some morphologic or qualitative characteristic; or else in honor of some personage who had to do with botany; or rarely, iHist. Stir p., p. 892. 'Ibid., p. 895. LANDMARKS OF BOTANICAL HISTORY — GREENE from some foreign country whence the plant or tree had been in- troduced into Europe. But there is nothing of the meaningless and cabalistic in any of the 343 generic names that head as many Fuchsian chapters. The meaning is not in every instance plainly to be 'read in the name itself. That which it once had when newly coined, has now and then become obscure, if not quite lost, through the lapse of ages. But there are not yet in botany anagrammatic names, nor any that had been framed by the putting together of two or three meaningless though perhaps euphonious syllables. The beginnings of such an epoch in nomenclature we shall not Jook for until after the time of Linnaeus. In specific nomenclature, however, we note in Fuchsius a free use of cabalistic names. In genera of two species one is very apt to be named mas, the other fasmina, and since at that time nothing was known about sexuality in plants, such names had little mean- ing. But quite as frequently the first species is called prima, the other altera; and in the case of his fine plates of six species^of Geranium, they are named G. primum, G. alterum, G. tertium, G. quartum, G. quintum and G. sextum.1 Though without a trace of diagnostic significancy, and purely cabalistic, we shall find that this kind of specific adjective came into use very extensively in the works of botanists of a generation later than Fuchsius. 1 Hist. Stirp, pp. 204-210. CHAPTER VII HIERONYMUS TRAGUS 1498-1554 AN original and even eccentric character, singularly gifted as a botanist, was Hieronymus Bock, whose names in literature are several ; for his earliest publications were made in Latin, under the name Hieronymus Herbarius. Brunfels in his first volume publishes a number of paragraphs the manuscript of which had been furnished by his friend Bock, and these are all credited to him as Hieronymus Herbarius — Jerome Botanist, or Jerome Herbalist, as you like. So again, in the Appendix to Brunfels' second volume, there is a document of some length, entitled Apodixis Germanica.1 This is in German, and is by Tragus, but still under the name Hieronymus Herbarius. In the numerous German issues of his principal work he figures as an author whose name is Hieronymus Bock. When the great botanical merit of this work had been intimated abroad, and a Latin edition of it was thereby called for, in this he appeared under the Graeco-Latin name Hieronymus Tragus. By this name therefore is he known in the botanical world in general. The genus that was dedicated to him by Father Plumier therefore necessarily took the form of TRAGIA. Life. No adequate biography of this interesting character seems to be known. We trust that we have to a certainty the year of his birth ; we have the date of his marriage, the maiden name of the bride, the names of her parents, and even the number of guests that were in attendance ; and all this out of Tragus' own diary.2 Neither is there any disputing the date of his death, the place of his burial, or the name of the preacher who delivered the funeral pane- gyric. But all these are matters which, in the biography of a reputed scholar, a practicing physician, and the beneficiary of a lucrative parochial endowment, are of subordinate interest. What one most wishes to know are the names of the colleges and universities at which the man studied, the schools whence he had his 1 Brunfels, Viv.
