Since then, a number of exotic species have been introduced, making considerable additions to the cultivated col- lections in this country, of which the names of many have from time to time been noticed in the Horti- cultural Journals and in Nurserymen's Catalogues. These I have collected and arranged under their respective genera and tribes, so as to form an Appendix to the present edition. I, however, deem it necessary to state, that shortly after the publication of the first edition in 1866, my sight entirely failed, and consequently I have not been able to follow up my rule, which was, not to enter a species on the list of living plants without first having seen it growing, or had specimens sent me taken from plants cultivated in this country. It being impossible for me now to do so, I have consequently availed myself of the great knowledge of Ferns possessed by Mr. William Grower, formerly foreman of the Fern collec- tion at Kew, whose name is already noticed in the Vlil PREFACE TO THE SECOND EDITION. • preface of the first edition, and who being well acquainted with the principal Fern collections in this country, makes it a special point to obtain a know- ledge of all new introductions. For my knowledge of the additions to the Kew collection since 1864, I am indebted to the kindness of Dr. Hooker for having mentioned to Mr. Baker, the Assistant Curator in the Kew Herbarium, my desire to obtain a list of the new introductions, which he readily furnished me ; and whom I have also further to thank for special information regarding certain species. The number of new species introduced since the last enumeration amount to 234, of which the names of about one-half are derived from Mr. Baker's list, some of which are specially interesting as consti- tuting several genera new to this work, which will be found noticed under their respective tribes. I continue to follow Sir William Hooker's " Species Filicum " * in the adoption of specific names and synonyms as far as possible ; at the same time availing myself of certain corrections, made by Mr. J. Gr. Baker in a work entitled " Synopsis Filicum," being an abridgment of the " Species Filicum," — this work was commenced by Sir William Hooker, the first part of which was published in 1865, only a few months before the death of that celebrated Pteridologist ; it was, however, taken up and completed by Mr. Baker, forming a volume of 482 pages, containing brief * A work in five volumes, being a description of all known ferns. PREFACE TO THE SECOND EDITION. IX descriptions of 2,228 species. A second edition of this work was published in 1874, with an Appendix, which contains the descriptions of 438 new species ; thus making the total number of known ferns, as identified by the Kew Herbarium, to amount to 2,646. In this work Mr. Baker has, however, made consider- able alterations in the nomenclature and synonyme, as given in the ts Species Filicum," which adds addi- tional testimony to what I have stated at page 56. The propriety of making such, whether right or wrong, is not necessary for me to comment on here,* for to do so would lead to this Appendix being much enlarged, and only burden genera and species with additional synonyms, which, for the sake of amateur cultivators of Ferns, I deem it prudent to avoid as much as possible ; it is only in a few special cases that I have thought it necessary to change or add synonyms to names in the original enumeration. I felt desirous to state the name by whom each individual species was introduced, but I found this to be a difficult task, and therefore deem it sufficient to state, that the principal introducers were the following nurserymen: — Messrs. Backhouse, York; Bull, King's Road, Chelsea; Henderson, Pine-apple Place, Edg- ware Road ; Jackson, Kingston ; Standish, Ascot ; Stansfield, Todmorden; Yeitch, King's Road, Chelsea; and Williams, Holloway. * For full particulars on this point see my " Historia Filicum," a work of 429 pages, with 29 lithographic plates, published by Macmillan & Co., 1875. 1X PREFACE TO THE SECOND EDITION. In consequence of trade collectors and importers of new plants being desirous of bringing them into early public notice, names are given them without having first taken the precaution to ascertain whether they are not already named and described in Botanical works ; thus names frequently appear in Nurserymen's Catalogues, as new, without descriptions, or even their native country given.* Many of such introductions are, however, from time to time described in the Gar- dener's Chronicle by Mr. T. Moore, whose knowledge and writings on ferns are sufficient to warrant their adoption as new species. I have, therefore, in the present addenda, omitted many of these provisional names. In the plant catalogues of Nurserymen who make ferns a special object of trade, besides the enumeration of specific names, a great number of what are called varieties are also recorded, and their prices affixed, of which Mr. Stansfield's Catalogue contains the names of nearly 500. These consist of abnormal forms of a few British species, principally of Asplenium FiliM-fcemina, Lastrea Filix-mas, PolysticJium aculeatum, Scolopen- drium vulgare, Lomaria Spicant, and Polypodium vulgare, to which numbers of new forms are yearly * It should be made a special rule that all importers or pos- sessors of supposed new plants, before offering them for sale, should have them examined by some competent authority, for which there is now ample means in the National Botanical Establishment of Kew, either by examining the living plants in the garden, or in the Herbarium, or by books in the library, or the Herbarium in the British Museum, which now contains my Fern collection. PREFACE TO THE SECOND EDITION. XI being added by cultivation, or found wild. The exhi- bition from time to time of these so-called varieties at the meetings of the Royal Horticultural Society, and the awarding of first-class certificates, are indicators of the great interest in which the curious forms are held by amateurs. Varieties are also found amongst exotic species, especially in the genera Gymnogramma, Adiantum, and Pteris ; but these are comparatively few to those native of this country. That ferns still continue to be in favour with the plant-loving public, is manifest by the frequent public sales of large importations from abroad, especially of tree ferns, some of which are of large size, and valued as ornamental plants for conservatories, and at public or private banquets or balls, the prices vary ing accord- ing to height, from £5 to £50, or even more ; high prices are also given for species of certain genera, such as Adiantum, Gleichenia, Todea, &c. With regard to cultivation, I have nothing to add to what I have already given in the first edition. J. SMITH, JKx-Curator, Royal Botanic Gardens, Kew. July, 1876. PREFACE TO THE HEST EDITION. NEAELY ten years have now elapsed since my " Catalogue of Cultivated Ferns " was pub- lished. During that period many new and fine species have been introduced to the gardens of this country. I have therefore been induced to draw up the follow- ing enumeration, including in it all the species that have come under my notice in a living state, either by the evidence of plants in the Kew collection or by specimens from living plants sent me from various sources. Thinking it might be interesting to Fern growers, I have drawn up a brief history of the introduction of Exotic Ferns from the earliest records to the present time. In order to assist students in the study of Ferns, an explanation is given of the principal organs and terms used in describing them, as well as remarks on their classification. I have also given an alpha- betical list of the generic names, accompanied with the derivation of each name. Great complaints are frequently made, and not with- xiv PREFACE. out good reason, of the many names given to the same plant ; to assist in correcting this, I have drawn up a complete Index of the species and synonymes noticed in this work ; therefore, by turning to the page referred to in the Index, the name will be found either with a number before it showing it to be the adopted name, or following the same as a synonyme, or what it has been and is still called by some writers and cultivators. Although this Index contains nearly three thousand names, yet, it must be understood, I have only taken up the synonymes that I consider most essential; those who desire to enter more fully into this subject, may consult the " Index Filicum" of Mr. T. Moore — a work which, when completed, will be a treasure to pteridologists. With regard to the wood-cuts, I have to explain that about half of the number were not specially pre- pared for this work; these, in general, represent a portion of the fronds of their natural size, in some cases without fructification, the venation only being given. The drawings for the other half have been made principally from specimens in my herbarium or from living plants. In many of them a magnified portion of the frond ia given, showing the character of the genus more distinctly. As a companion to the scientific enumeration, I have given a treatise on their cultivation, which occu- pies a considerable space in this book, and it is hoped will be of service to the Fern-growing public. PEEFACE. xv In drawing up this treatise I have been greatly assisted by Mr. Henry Prestoe and Mr. William Gower (both recently foremen in the Fern department at Kew), two highly scientific and nature-observing practical cultivators. In conclusion, I have to thank Dr. Berthold Seemann and R. Heward, Esq., for looking over the proofs as they passed through the press. Several causes have occurred to delay the publication of this work; the principal one being a partial failure of my sight, incapacitating me from much use of the pen and examination of new garden Ferns, which I trust will be accepted as my excuse for any errors or omissions that may be found in the following pages.

HISTORY OF INTRODUCTION OF EXOTIC FERNS. fin HOUGH Ferns now occupy a conspicuous place JL in our gardens, and are in high favour with cultivators, it is only in comparatively recent times that they have been brought into notice. During the last century certain classes of plants came into fashion, and after a season of popularity again fell into disrepute. Thus : Tulips were once the rage. At the time of the establishing of the several pro- vincial Botanic Gardens, all of which were founded upon a strictly botanical footing, though many of them have now, to a greater or less extent, degenerated into places of amusement, the plants in greatest demand were those of our New Holland and Cape colonies, principally the Heaths, Proteas, Aloes, and their kindred. In after-years dealers obtained large prices for Cactuses; but, with the exception of a few of the easily-grown and most showy kinds, these are now scarcely saleable. Still more recently the magni- ficent-flowering Orchids were promoted to the first place in our gardens ; and though these may still be said to maintain their position, the expense attending £S;&NS,:-: BRITISH AND FOREIGN. isv .so great that they are for the most part confined to the gardens of the wealthy. Ferns, on the contrary, may, as a general rule, be grown in a comparatively inexpensive manner. The discovery made by Mr. N. B. Ward, that these plants can be grown to great perfection in small ornamental closed cases (now well known as ' { Wardian Cases "), suitable not only for the drawing-rooms of the wealthy, but for humbler dwellings, renders it pos- sible for amateurs to indulge their love of Ferns without going to the expense of erecting hothouses and em- ploying a staff of gardeners; and it is to be hoped that this will be the means of retaining them in favour and spreading them still wider. The enumeration in the following pages shows that at the present time above nine hundred exotic species of Ferns are cultivated in the various public and private gardens in this country; and of these by far the greater number have been introduced during the last quarter of a century. A very large, indeed almost a complete, collection of them may at present be seen in the Royal Botanic Garden at Kew, where, during forty years, I devoted attention to their cultivation, and to the study of their generic and specific distinctions, using every endeavour in my power, assisted by the extensive influence of the eminent Director, Sir W. J. Hooker, to introduce new species, both by raising -them from spores taken from my herbarium, and through correspon- dence with persons residing in our Colonies and the Superintendents of Botanic and other gardens on the Continent. Being well acquainted with the latter branch of the subject, — the introduction of new HISTORY OF INTRODUCTION OF EXOTIC FERNS. 3 species, — I have thought that a few pages devoted to the history of these plants in its connection with our gardens might prove acceptable. My own personal knowledge dates from about the year 1822 ; and for information respecting those in cultivation previous to that time, I have taken for my guide the most im- portant and most reliable of the garden catalogues. The first work upon which dependence can be placed for the early-introduced species is the so-called second edition of the " Hortus Kewensis," published by the younger Aiton, in 1813; I say the so-called, for there were in reality two previous editions — one by Dr. John Hill, in 1768, and a second by William Aiton, in 1789. In the first of these only ten exotic species are recorded as being in the garden at Kew, which then belonged to the Princess of Wales, but the dates of their introduction are not given; and in the second, that of the elder Aiton, thirty-four, all of which have the name of their supposed introducer attached to them, and the date at which they were introduced. I here give preference to the last edition, as I know, from personal intercourse with the com- pilers, that great care was exercised in its prepara- tion, particularly with regard to the rectification of dates, and I shall take it as the basis of my remarks. But, in the first place, it is necessary to say a few words in defence of that work. It has been asserted that a considerable number of the plants enumerated in the ' e Hortus Kewensis " never existed in a living state, either in the garden at Kew or elsewhere in this country. This statement, however, is merely supposition, and rests upon questionable authority. In the early days of Kew Gardens, large B 2 4.« FERNS I BRITISH AND FOREIGN. sums of money were devoted to the payment of bota- nical collectors, and great exertions were made, under tiie patronage of Sir Joseph Banks, to stimulate the introduction of new and rare plants, by inducing the commanders of ships of war and East- Indiamen to take an interest in the subject. By these means a very large number of plants were actually introduced into the country in a living state ; but the Department under whose charge the garden then was, took no steps to provide proper accommodation ; and this, together with the very frequent change of foremen, led, as a natural consequence, to the death of the plants. Taking, then, the third " Hortus Kewensis," and excluding our indigenous species, I find that the total number of " Garden Ferns " introduced previously to the year 1813 amounts to as many as eighty-three. The merit of being the first introducer of these plants belongs to Mr. John Tradescant* the younger, who in early life made a voyage to Virginia ; and I find it recorded in Parkinson's " Theatrurn Botanicum," published in 1640, that upon his return from that country in 1628 he brought with him, amongst other rare plants, the Cystopteris bulbifera and Adiantum peddtivm. These, therefore, must be regarded as the nucleus of our present large collections. At first the progress seems to have been exceedingly slow, for between the time of Tradescant and the close of the seventeenth century, only five additional species were introduced ; viz., Asplenium rhizophyllum and Onoclea * John Tradescant had a Botanic Garden and Museum at LamLeth. HISTORY OF INTRODUCTION OF EXOTTC FERNS. 5 seusibilis from North America, the former in 1680 and the latter in 1699, in which year also Adiantum reni- forme and Davallia Canariensis were brought from Madeira, while the fifth, Blechnum austrak, was, according to Plukenet, who figured it in the second part of his " Phytographia," cultivated in the King's garden at Hampton Court as early as the year 1671, when his work was published, the garden there containing a considerable collection of rare plants. During the next forty-two years no additions appear to have been made, excepting the Phlcbodiiim aureum, which was introduced by Lord Petre at some time prior to 1742, the date of his death, the precise year being unknown. Progressing onwards, I do not find any more recorded until the year 1 769 ; but between that year and the commencement of the following century sixty-eight species were added to the eight already existing in our gardens. Out of this large number, no less than thirty-seven were brought home by Rear- Admiral Bligh, in H.M.S. Providence, on his return, in 1793, from his second voyage, undertaken for the purpose of introducing the Bread-fruit and other useful trees into our West Indian colonies. And, finally, during the first few years of the present century, up to 1813, the date- of the publication of the "Hortus Kewensis," seven others were introduced. A summary of the foregoing shows that upwards of one-half of the Ferns known at the last-mentioned date were West Indian species, forty-four having been received at various times from those islands, the majority through Blights expedition. North America and Madeira, with the neighbouring islands, stand G FERNS : BRITISH AND FOREIGN. next as the largest contributors, fifteen having been introduced from the former and twelve from the latter country ; while of the remaining sixteen, four appear to have come from the East Indies, four from the Cape of Good Hope, three from New Holland, and one from St. Helena, — making in all eighty-three species. The next catalogue of garden plants worthy of notice is the "Hortus Suburbanus Londinensis," published in 1818, only five years after the " Hortus Kewensis," by Mr. Sweet, the Superintendent of the then celebrated nursery of Mr. Colville, at Chelsea. In it I find an enumeration of one hundred and eight exotic ferns ; but this work, like the similar more im- portant " Hortus Britannicus," brought out by the in- defatigable London in 1 830, and which contains no less than three hundred and thirty exotic Ferns, includes not only a considerable proportion of bad species, but also a large number that did not really exist in British gardens, many having been entered without authentic evidence, and others added upon the mere expectation that they might shortly be introduced, — expectations which, in many cases, have not been realized to this day. No reliance can therefore be placed upon either of these works, and I cannot accept them as authorities. During the latter part of the eighteenth century and the commencement of the nineteenth, the only pri- vate individuals who turned their attention, with any amount of energy, to the introduction of new and rare plants, were the long- and far-famed nurserymen at Hackney, the Messrs. Loddiges ; and ' to them we owe the greater part, if not the whole, of tho HISTORY OF INTRODUCTION OP EXOTIC FERNS. 7 Ferns existing at that period in British gardens, and not included in the " Hortus Kewensis." Speaking from my personal recollection of the im- portant collection of plants in the Hackney Nursery, as it existed in the year 1825, I think it contained about a hundred good species of exotic Ferns ; but I can obtain no earlier catalogue than one published in 1849, in which two hundred and fifty-one are enumerated. In the year 1822 I found the collection of Ferns at Kew extremely poor, especially as regards Tropical species, very many of those introduced in previous years having been lost, and very few new ones added. Any person who remembers the hothouses in existence forty years ago, will have but little difficulty in accounting for the falling off of the Fern collection. In those days hot-water pipes were unknown, and the houses were exclusively heated by means of brick flues, too often imperfectly constructed, and the excessively dry and ungenial atmosphere thus induced was quite unsuited for the good cultivation or even for the mere preservation of these moisture- loving plants. Nearly all the North American species enumerated in the ' ' Hortus Kewensis " were growing very finely in a north border, and most of the Madeira species were also in existence; but, including these and the few added since 1813, I cannot estimate the entire Kew collection of exotic Ferns at that period at more than forty species. Between 1813 and 1846, when my first Catalogue of the Ferns at Kew appeared, no reliable list was published in this country. Several, however, were brought out by Continental botanists, which 8 FEKNS I BRITISH AND FOREIGN. are of sufficient importance to be worthy of a passing notice. The first of these in point of date is the " Enumeratio Plantarum Horti Kegii Botanici Bero- linensis," by Wildenow, published in 1809, with a Supplement by Schlechtendal, bringing it down to 1813. We are thus enabled to compare the num- bers in the Kew and Berlin gardens at the same period; which were eighty-three in the former, and thirty in the latter, including eleven not known at Kew. During the succeeding nine years more atten- tion appears to have been given to Ferns at the Berlin garden ; for Link, in his first " Enumeratio," in 1822, describes ninety-one exotic species, which is more than double the number then existing at Kew. After this the increase in number was still more rapid; for in the second edition of Link's " Enumeratio," published in 1833, no less than two hundred and thirty-nine are described ; and in the third, in 1841, two hundred and fifty-eight, exclusive of varieties. By this time, however, the collection at Kew had received large additions, both through importations of living plants and by raising from spores. In 1845 it was so extensive that I was induced to draw up a classified enumeration, which was pub- lished as an appendix to the Botanical Magazine for 1846. The number of exotic species there enume- rated is three hundred and forty-eight, and I do not think many were to be found in other gardens in this country which were not at Kew, so that the Kew list may be taken as a guide to the number then in British gardens generally. Four years later, Kunze, of Leipzig, contributed to HISTORY OP INTRODUCTION OP EXOTIC FERNS. 9 the 23rd volume of the "Linnasa" an alphabetical index of the Ferns cultivated in European gardens, and in this the large number of eight hundred and forty-three exotic species are enumerated; but the authorities upon which a very considerable portion of these were inserted cannot be relied upon, many names having been taken from such catalogues as those of Sweet, Loudon, &c., and I am therefore obliged to con- clude that the number given by Kunze as living in Europe in 1850 is greatly exaggerated. This con- clusion, too, is confirmed by the fact that in 1857, after I had by correspondence become acquainted with the collections in the principal gardens on the Conti- nent, and after that at Kew had obtained most of their novelties by means of exchange, I could, in my " Catalogue of Cultivated Ferns," enumerate only five hundred and sixty exotic species as known in British gardens. Since the last-mentioned year, the con- stantly increasing demand for Ferns consequent upon their wider spread cultivation, has greatly stimulated the introduction of new ones, and our collections have increased at the rate of about fifty species a year. It now remains to say a few words regarding the means by which these plants have been obtained, and the persons who have been most active in introducing them, taking the Kew collection as a foundation. Firstly, with reference to the paid collectors employed in various parts of the world, directly or indirectly in the service of the Royal Botanic Garden, Kew, and to whom that garden is indebted for additions to its Fern collection. It would appear that so long back as the year 1775 Mr. Francis Masson, one of the earliest, if 10 FERNS: BRITISH AND FOREIGN. not the earliest, collector sent out from Kew, ancl who succeeded in introducing large numbers of Capo Proteacece and Ericaceae, sent home several Ferns from the Cape of Good Hope and Madeira. This col- lector proceeded to the Cape in 1774, and came home by way of Madeira about the year 1778, returning again in 1736, and remaining at the Cape during the nine following years. Early in the present century Mr. George Caley, who was originally a horse-doctor,, residing near Birmingham, but acquired a love for plants through collecting herbs, was sent out by Sir Joseph Banks to New South Wales, and to him we owe Platy cerium alcicorne, Doodia aspera, and Davallia pyxidata, the first introductions from Aus- tralia, received about the year 1808. The next col- lectors to whom the garden was indebted for Ferns, are the Messrs. Allan Cunningham and James Bowie. They left Kew in 1814, on a botanical expedition to Brazil, where they remained exploring the country and sending home large collections till 1816, when the former proceeded to New South Wales, and the latter to the Cape of Good Hope. No living Ferns appear to have resulted from the Brazilian ex- pedition ; but several Australian species and one or two from Norfolk Island were received from Mr. Cunningham, and two or three from Mr. Bowie from the Cape. Several other collectors were employed in the ser- vice of these gardens, when under the Directorship of Mr. Aiton, such as Messrs. Barclay and Armstrong ; but I can trace no Ferns to them, nor, with certainty, to David Lockhart, a gardener from Kew, who accom- panied the ill-fated expedition of Captain Tuckey up HISTORY OF INTRODUCTION OF EXOTIC FERNS. 11 the Congo, in 1816, though I believe it possible that some of the first-known Western- African species aro attributable to him. Lockhart was one of the few who did not fall a victim to the deadly climate of that country. After lying a long time in the hospital at Bahia, he returned to England, and shortly afterwards received the appointment of Superintendent of the- Botanic Garden in Trinidad, where he died in 1845r after a service of a quarter of a century in that island,, during which period he sent many fine plants to Kew. The principal collectors employed directly or indi- rectly in the service of Kew during the Directorship of Sir William Hooker, and to whom the garden is in- debted for any additions to its Fern collection, are Messrs. Pur die, Seemann, Milne, Barter, and Mann. The first of these, Mr. Y^illiam Purdie, was engaged as- collector in 1843, in which year he was despatched to Jamaica, and after spending several months in the- exploration of that island, and forwarding many valuable plants to Kew, he proceeded to Santa Martha, and was employed for more than two- years in various parts of New Granada. To him we are indebted not only for numerous showy flowering* plants, but for a considerable number of our garden Ferns. Upon the death of Mr. Thomas Edmonston,* Mr. (now Dr.) Berthold Seemann was appointed his suc- cessor, as botanist to H.M.S. Herald, and joined that vessel at Panama, in January, 1847, remaining with her until her return to England in June, 1851. Previously * Mr. Edmonston was shot by the accidental discharge of a rifle, at Sua Bay, Ecuador, January 24, 1846. 12 FERNS: BRITISH AND FOREIGN. to joining the Herald, he explored several parts of Panama and Veraguas, and while on board the Herald visited various parts of the western coast of America, between Lima on the south and California on the north, occasionally making long journeys inland, particularly in Peru, Ecuador, and Mexico. He likewise accompanied the Herald in her three voyages to the Arctic regions in search of the ill-fated Sir John Franklin ; visited twice the Sand- wich Islands ; and returned home by way of Hong- Kong, Singapore, and the Cape of Good Hope. Not- withstanding the few facilities afforded by surveying expeditions for collecting living plants, Dr. Seemann succeeded in introducing some interesting ones to our gardens ; and among Ferns we may mention two very remarkable ones, Deparia prolifcra from the Sandwich Islands, and Dietyoxiphium Panamense from Panama. On the Herald being recommissioned in 1852, Mr. William Milne was appointed assistant-botanist, for the special purpose of collecting plants for the Royal Gardens. During the six years he was attached to the Herald he visited New Caledonia, the Fiji, and other Polynesian islands, as well as many other places in the southern hemisphere. The Admiralty having, early in 1857, determined upon sending out a second exploring expedition up the Niger, under the command of Dr. Baikie, R.N., Mr. Charles Barter, a zealous and intelligent young gardener, was appointed to accompany him in the capacity of botanist, and to collect plants for Kew. The officers of the expedition proceeded by way of Sierra Leone., and joined the Day spring, a small HISTOEY OF INTRODUCTION OF EXOTIC FEENS. 13 vessel fitted for river navigation, at Fernando Po ; but, unfortunately, after they had penetrated up the river as far as Nupe, their ship was wrecked, and they were obliged to form a camp on the banks. Poor Barter, however, fell a victim to the deadly climate in July, 1859. As a collector he was indefatigable in the dis- charge of his duties, and discovered a large number of undescribed plants, including several new genera, one of which has been dedicated to his memory under the name of Barteria. But, owing to the mishaps attending this expedition, and the difficulties of transit, no living plants were received from the interior of the country, but several Ferns were trans- mitted from Sierra Leone and Fernando Po.* No sooner had the news of Barter's death arrived, than Mr. Gustav Mann, undeterred by his fate, volunteered to fill the vacancy, and was appointed accordingly. Being unable, from want of means of communication, to join Dr. Baikie, he was employed for three years in exploring the island of Fernando Po and the African coast, in the neighbourhood of the Camaroons and Gaboon rivers. In spite of the difficulties and dangers attending the under- taking, he made several ascents of the lofty Clarence Peak of Fernando Po and of the Camaroons moun- tain on the African mainland. On the former, at an elevation of 5,000 feet, he found a fine new Cyathea, forming groups, with stems rising to a height of 30 feet. We are likewise indebted to him * Since the above was written, news has reached this country of the death of Dr. Baikie at Sierra Leone, in January, 1865, whilst on his homeward voyage. 14 FEENS I BRITISH AND FOREIGN. for many other rare and interesting living Ferns, and fine sets of dried specimens. Besides contributions from special collectors, the Fern collection at Kew has been largely increased through the instrumentality of the officers of our numerous Colonial Botanic Gardens, and likewise by many private individuals residing in foreign countries ; and as the exertions of these gentlemen are worthy of being recorded, I give a few particulars respecting them, adopting a geographical arrangement for the sake of brevity. The first Colonial garden from which, so far as I am aware, Ferns were received at Kew, was that of Ceylon, Mr. Alexander Moon, the Director, having, in 1824, sent home a collection of plants, amongst which was Nipliobolus costatus. But the first person who forwarded any considerable number from that island was the lamented Mr. George Gardner, well known to botanists as a botanical traveller in Brazil, who was Director of the Ceylon garden between 1844 and his death in 1848. This gentleman was succeeded by Mr. (now Dr.) G. H. K. Thwaites, the present able Director, and to him also the Kew collection is greatly indebted for a large number of rare and beautiful species ; such as ficJiizoccena sinuata, Asplenium radiatum, Actinostacliys radiata, HelmintJiostacJiys Zeylanica, and many others. Though Continental India is extremely rich in Ferns, it has, singularly enough, contributed very few to our gardens, no persons in that country having devoted themselves specially to the subject ; indeed most of those received thence have been accidentally imported along with Orchids, including the half-dozen species HISTORY OP INTRODUCTION OF EXOTIC FERNS. 15 recorded in my first Enumeration as coming from Dr. Wallich, the only Superintendent of the Calcutta garden who has the credit of having introduced any. Indeed, with the exception of those from Ceylon, Kew has received very few Ferns from Asia and the adjacent islands, most of those now in cultivation having been introduced by nurserymen or through Continental gardens. Two or three were brought from Hong-Kong, in 1850, by Mr. J. C. Braine, including one which proved to be a new genus, and to this I gave the name of Brainea in honour of its introducer. Another tropical island in the Eastern hemisphere, whence large additions have been made to the Fern collection at Kew, is the Mauritius. The Botanic Garden in that island has long enjoyed the reputation of possessing a fine set of plants ; but until the year 1852, when it came under the able management of the present Director, Mr. James Duncan, very little correspondence was kept up with the gardens of Europe. Mr. Duncan has, at considerable risk, ransacked the forests of the island in quest principally of Ferns, and has been very successful in transmitting living plants to this country, enriching our gardens with many fine species. The " Synopsis Filicum Capensis" of Pappe and Eawson shows that the Fern Flora of Southern Africa is extremely rich ; but up to the present time we possess scarcely a dozen Cape species in our gardens, and most of them have been raised from spores. Alsophila Capcnsis and Lomaria, Capensis were intro- duced in 1845 by Mr. Charles Zeyher, as also were Lastrca athmantica and Cyathea Dregei from Natal by Mr. J. Plant. 16 FERNS : BRITISH AND FOREIGN. Progressing westwards we come to the two strangely isolated islands in the Southern Atlantic, St. Helena and Ascension. From the former of these we have As- plenium compressum, introduced by Mr. Thomas Fraser in 1825, and Asplenium reclinatum, brought home by Dr. J. D. Hooker on his return from Sir John Ross's Antarctic expedition in 1844; together with Lomaria alpina and L. Magellanica from the Falkland Islands ; while from Ascension Mr. Wren sent numerous fine plants of Marattia purpurcscens in 1848. From Australia several individuals have been con- tributors. Grammitis Australis was received from the- Sydney garden in 1833, when under the direction of Mr. Richard Cunningham; and Mr. Charles Moore, the present Director of that garden, has also intro- duced several, including Trichiocarpa Moorei, from New Caledonia, while to Mr. Bidwill we owe the curious Platycerium grande. But some of the most beautiful of the Australian Ferns, such as the Glei- chenias, were transmitted to this country by Mr. Walter Hill, the able Director of the Botanic Garden of Brisbane, in the rapidly rising colony of Queensland, who obtained them during his stay in Sydney in 1850. Two species of Gleicheniacece were,, however, previously known in our gardens, — the Glei- chenia microphytta and G. flabellata, both of which, together with several other Ferns, were sent from Tasmania, in 1845, by Mr. Ronald Gunn. About the year 1841 or 1842, some very fine Ferns,, including two Tree-Ferns, the Dicksonia squarrosa and Cyathea medullaris, were brought from New Zealand, where they had been collected by Mr. J. Edgerly, a gardener, who had proceeded to that country on HISTORY OP INTRODUCTION OP EXOTIC PERNS. 17 speculation, and who was the first to introduce the beautiful Veronica speciosa. Others have also been sent from New Zealand by the Kev. William Colenso, and by the late Dr. Sinclair, K.N., the beautiful little TricJwmanes reniforme being one of those due to the latter gentleman. Turning next to the West Indies, we commence with the island of Jamaica, whence more Ferns have been received at Kew than from any other part of the Western hemisphere. The person to whose energy and perseverance this is mainly due is Mr. Nathaniel Wilson, the Island botanist and Director of the Botanic Garden. He has been a resident in the island for upwards of twenty years, and during that time has thoroughly explored the Blue Mountains and other districts rich in Ferns, liberally forwarding to Kew the results of his numerous journeys. Among his earliest contributions was the beautiful Tree-fern, Cyathea arborea, which, though recorded in the ' c Hortus Kewensis " as having been brought home by Admiral Bligh in 1793, had long been lost to our gardens. Within the last few years he has succeeded, after many failures, in transmitting numerous species of TricJwmanes and HymenophyUum, which now form so conspicuous a feature in the present rich collection. The other contributors from the same island are, in 1851, Mr. George Manson, and in 1854 and following years, W. T. March, Esq., the latter gentleman sending several arborescent species as well as Hymenophyllece, and others. Numerous fine species, including several Cyatheas and JisopMas, were received in 1855 and 1856 from the French island of Martinique, where they had been 18 FERNS : BRITISH AND FOREIGN. collected by the Director of the Garden, M. Belanger.. A considerable number of rare species were likewise* sent from Dominica in 1853, and several following years, by Dr. Imray ; such as Hemitelia Imray ana, Neurocallis 2ircestantissima, ElapJioglossum undulaium, and the true E. longifolium, &c. While from Trinidad we are indebted to the Island botanist, the late Dr. Criiger, for Schizcea elegans, Saccoloma elegans, Amphidesmium rostratum, Hymenostachys diver sifrons, TricJiomanes- pennatum, and other equally rare species. His suc- cessor, Mr. Henry Prestoe, who previous to his appoint* ment last year was foreman of the collection of Ferns at Kew, has already transmitted a large collection of rare Ferns, and in the finest condition, proving that they had been collected and put up by one who perfectly understood their nature. The situation he now holds will enable him to be of great service in transmitting new plants to this country. Comparatively few, considering the richness of its Fern Flora, have been received from tropical America; Dr. Gardner and J. Wetherall, Esq., in Brazil; H. Cadogan Kothery, Esq., in Guiana; Mrs. Colonel McDonald, in Honduras ; and Mr. Wagener, in Vene- zuela, being the principal contributors. From the above it will be seen that a large number- of Ferns have been introduced through the agency of the garden at Kew; but, besides these, a very con- siderable number are due to the exertions of some of our leading nurserymen, who, in consequence of the great demand for, and the large prices realized by, the finer and rarer species, have imported them, either- direct from their native countries, or from the Con- tinent, where, as will be presently noticed, a good HISTORY OF INTRODUCTION OF EXOTIC FERNS. 19 many species not previously known in the gardens of this country have been introduced. I have already alluded to the Messrs. Loddiges, of Hackney, as having at an early period turned their attention to Ferns, and as being the earliest to form a collection of them. But the only nurserymen whose names are recorded in the second edition of the " Hortus Kewensis " are the old-established firm of Messrs. Lee & Kennedy, of Hammersmith, who are stated to have introduced Polypodium asplenifolium and Asplenium monantJiemum in 1790 : in later times the Messrs. Lee have imported several from New Zealand. Other New Zealand species have been brought into notice by Mr. Standish, of Bagshot, they having been collected in New Zealand by Mr. J. Watson, now a nurseryman at St. Alban's, and who still continues to import. Several sent from Japan by Mr. Fortune have likewise been sent out from Mr. Standish's nursery. To the Messrs. Low & Sons, of the Clapton nursery, we are indebted for some rare Bornean and Malayan species, collected by Mr. Hugh Low, jun., and amongst others for the remarkable Arthropteris obliterata, called Lindscea Lowii in the gardens, and the little curious Leucostegia : parvula ; but more especially many rare species of Hymenophyllum and Tricliomanes, as well as the rare Thyrsopteris elegans, collected by Mr. Thomas Bridges in Juan Fernandez. But to the Messrs. Yeitch & Sons, of Exeter and Chelsea, among nurserymen, must be assigned the credit of having introduced the greatest number of these plants, the collectors employed by them in Chili and other parts of the American continent, in India, the Malayan continent c 2 20 FERNS : BRITISH AND 'FOREIGN. and islands, and in Japan, having sent home numerous fine species, while through other sources they have obtained many additions from Australia, New Zea- land, and other countries. Messrs. Rollisson, of Tooting, have likewise succeeded in enriching our collections with a considerable number, received principally from Mr. John Henshall, their collector in Java and the neighbouring islands. Mr. Robert Sim, of Foot's Cray, has an extensive collection, which he increases by importations, and is very successful in raising plants from spores ; and the Messrs. Back- house & Son, of York, the principal nurserymen cultivators of exotic Ferns in the provinces, have introduced a good many fine species of Trichomanes, and others from Chili and the West Indies. A few have likewise been introduced by other nurserymen, but the above are the principal of those who have obtained them from their native countries. I may, however, mention Messrs. Osborn & Sons, of Fulham, as having introduced one or two from Tasmania; Messrs. Jackson & Son, of Kingston, the Angiopteris Assamica, from Assam ; and Mr. B. Williams several from various parts ; while all these and some others have also imported considerable numbers from the Continental gardens and nurseries. In addition to all these sources, occasional intro- ductions have taken place through several other Botanic Gardens in this country, as well as through some of the numerous amateur cultivators ; but Fern amateurs have increased so largely during the last few years, that it is obviously impossible to mention them in detail. With respect to the former, the first; provincial Botanic Garden in which Ferns were brought HISTOEY OF INTRODUCTION OF EXOTIC FEENS. 21 into notice was that of Liverpool, under the Curator- ship of the late Mr. John Shepherd, more than thirty years ago; and the collection there has lately been considerably augmented by Mr. Tyerman. At Bir- mingham, too, Mr. David Cameron in early times formed a good collection, which, however, has now given place to gaudy florist flowers. A good deal of attention is at the present time paid to Ferns at the Glasgow Botanic Garden by Mr. Peter Clarke ; and also by Dr. David Moore, Director of the Botanic Garden of the Eoyal Society of Dublin, at Glasnevin, who has likewise introduced several new species from Trinidad and New South Wales. The Eoyal Horti- cultural Society of London must be mentioned as having introduced Cibotium Schiedei, and one or two other Mexican species, received from their collector, Mr. Theodore Hartweg. Want of space precludes my particularizing the numerous private growers of the present day; but I cannot altogether pass over one or two of the earlier ones who formed large collections of species, and did much to stimulate the taste for these plants. I more particularly allude to Mr. James Henderson and John Kiley, Esq. Under the patronage of the Earls of Fitzwilliam, to whom he had long been gardener, Mr. Henderson has for upwards of thirty years been a zealous cultivator of Ferns, and has been very successful in raising them from spores, adding by that means a good number of species to our collections. One of the earliest amateurs dis- tinguished for his love of Ferns, was John Kiley, Esq., of Papplewick, near Nottingham, who was also a successful raiser, and brought together a collection PERNS : BRITISH AND FOREIGN. containing nearly 300 species,, which, upon his death in 1846, was purchased by Dr. Forbes Young, of Lambeth, who considerably augmented it ; but unfor- tunately the death of its second owner, in 1859, caused its dispersion. Few amateurs at the present day study Ferns scientifically, or form collections numerically large in species, the principal of those in the neighbourhood of London devoting their atten- tion to a select number of the most beautiful ones, such as are well known to the frequenters of our metropolitan flower-shows. I must, however, except E. J. Lowe, Esq., of Beeston, near Nottingham, who formed a considerable collection, and published an illustrated work upon them in nine octavo volumes. In the public and private gardens on the Conti- nent Ferns claimed a large share of attention, and many of these possess fine collections of them, con- taining numerous species not yet known in British gardens, though our nurserymen are constantly on the look-out for novelties, and import a great number from these sources. I have mentioned above that the directors of the Botanic Garden of Berlin, at an early period, possessed an extensive collection, and many species are reputed to have been raised in this esta- blishment. The publication of the " Ferns of the Leipzig Garden," an illustrated work, in folio, by Dr. Mettenius, shows that the garden under his direction is exceedingly rich in Ferns, and the University fortu- nate in having a Professor so well able to do justice to the collection. At Vienna, also, a collection of Ferns has long existed under the direction of the late Dr. Schott. Several other German gardens, as those at Gcettingen and Herrenhausen, also possess a consider- HISTORY OP INTRODUCTION OP EXOTIC FERNS. 23 able number, some very interesting novelties in the latter having been obtained by M. Hermann Wend- land, during a journey through Central America ; and in many of these gardens species have been obtained by means of spores taken from dried specimens, while through the Dutch Botanic gardens, numerous rare Ferns have been introduced from Java, Surinam, and other Dutch colonies. Among private individuals on the Continent who have made large additions to our collections, by the introduction of species from their native countries, I cannot omit to notice M. J. Linden, of Brussels, who himself travelled in the West Indies, Venezuela, and New Granada, and who employed several enthu- siastic collectors in various parts of the same and neighbouring countries, by whom a great number of the new plants were brought into cultivation. But besides these M. Linden has also received several species new to our gardens, from New Caledonia and the Philippine Islands. About six years ago another private traveller in Venezuela and New Gra- nada, Dr. Karsten, likewise enriched continental gar- dens by the introduction of numerous fine species of tree and other Ferns, some of which have not yet been imported to this country. The total number of Ferns cultivated in our gardens at the present day may be regarded as forming about one-third of all the species known to botanists by means •of dried specimens, and described in the numerous works of pteridology. Among the remaining two- thirds are very many fine species, equal or supe- rior in merit, as garden plants, to any of those we already possess. It may be worth while to mention 24 FEENS : BKIT1SH AND FOREIGN. a few of the more striking of these, together with the countries in which they are found, in order to draw the attention of some of our enterprising nursery- men to them and induce them to take steps for their introduction. Assuredly in this fern-loving age many would prove of great commercial value. First, there is the magnificent Matonia pedinata, found only on Mount Ophir, in Malacca ; a Fern resembling the Gleichenias in habit, but rising to a height of five or six feet, with beautiful fronds, divided, like those of fan-palms, into numerous pectinate segments. Two other Ferns of much the same habit, the Dipteris Wallichii and D. Horsfieldii, are likewise worthy a place in our gardens. The former of these is found in the mountains of Silhet, and the latter in Java, Borneo, the Philippines, Fiji, and neighbouring islands. In the Philippine Islands, where the Fern Flora has about 250 representatives, there are numerous fine species, such as Dryostacliium splendent and Aglaomorplicu Meyeniana, both somewhat resembling Drynaria quer- cifolia in the general aspect and mode of growth of their barren fronds, both having rhizomes equally tenacious of life; Lomagramme pteroides, with large pinnate fronds three feet high, having long linear, lanceolate articulate pinnae, bearing amorphous sori; Phoiinopteris Horsfieldii, the glistening sterile fronds of which are pinnate and between two and three feet high, and have very broad elliptic-lanceolate pinna3, similar to the common laurel, while the fertile ones are very much contracted ; Gleichenia excelsa, a very strong-growing species with fronds five or six feet high, having spreading pinnse two to three feet in length. The beautiful Sckizoccena Brunonis of Penang and HISTOEY OF INTRODUCTION OP EXOTIC FEENS. 25 Malacca would also form a striking addition to our tropical ferneries, its pinnate fronds being from three to four feet long on stipes about half as long again, rising from an arborescent caudex. In Blume's ' ' Enumeration of the Ferns of Java " alone, no less than 460 species are described, of which about 300 are regarded as new. Many of them are, however, not distinct as species, but are fine and showy and well worth the cultivator's notice. Eemarkable for their structural characters, there are Sphceropl&ris larbata of Nepal, and Diacalpe aspidioides of Eastern Bengal and Java ; the fronds of the former resembling those of a Lastrea dilatata, but having globose sori with cup-shaped indusia elevated on distinct pedicels, while the latter has very similar sori not elevated. Another Fern of Eastern Bengal worthy of notice is the AcropTiorus nodosus, a species with large decompound fronds remarkable on account of their pinnaa standing out almost horizontally, or at right angles with the main rachis. The same district, including the Khasaya and Silhet hills, Assam, Bootan, Sikkim. &c., is extremely prolific in fine Ferns, which, though familiar enough in a botanical point of view, are still unknown in our gardens : they would yield a rich harvest to a collector of living plants; and it is not a little re- markable that so few of them have as yet been in- troduced through the Botanic Garden of Calcutta. The total number of known species of Indian Ferns* may be stated in round numbers to be 400 ; and what we have of these have been received from their other habitats. I cannot, of course, attempt to give a list of Indian desiderata ; but, in addition to the two or 26 FERXS : BRITISH AND FOREIGN. three above alluded to, I may mention Kaulfussia Asset - mica, a remarkable Marattiaceous Fern found in Assam, having ample trifoliate somewhat fleshy fronds, from eighteen inches to two feet in height, with the fructi- fication, which consists of hollow circular sporangia, scattered irregularly on the under surface. It is allied to the If. cesculifolia from the Malayan islands, in- cluded in the following enumeration, and which is extremely rare, if indeed it be not altogether lost from our gardens : Lomaria glauca, a Fern of Khasaya, "with pinnate fronds, fine glacous underneath, two feet high; and, finally, the Alsopldla gigantea, a native not only of Silhet, Nepal, and other parts of India, but of Ceylon, Penang, and other Indian islands, a magnificent Tree-fern with a trunk fifty feet high, bearing a crown of large bi- or tri-pinnate fronds, the segments of which are very variable. Dr. Thwaites, in his " Flora of Ceylon," enumerates 214 Ferns, of which about one-half are embodied in the following pages, but many are yet rare, and several have failed to become established. This is especially the case with Asplenium (Adiniopteris) radiatum, Actinostachys radiata, and the singular Polystichum anomalum, a most remarkable Fern, which bears perfect sori on both sides ; it is found at an elevation of from 5,000 to 6,000 feet, and no doubt our want of success in not keeping it, as well as the unhealthy look of other Ceylon Polystichums, is owing to their being placed in the tropical house, — their elevation and their resemblance to the European Polystichum aculeatum indicates that they would be more at home in the temperate house. Several interesting species have yet to be introduced, such as the small pinnatifid Poly- HISTOEY OP INTRODUCTION OF EXOTIC FERNS. 27 ?, including P. contignum and P. Emc-rsoni, which, oil account of their sporangia being seated in a deep cyst, and protruding outwards, are referred by some authors to Davallia. Two fine Tree-ferns are also worthy of notice, Alsophila crinita and Cyathea Wallteri. Many of the islands of the Eastern Archi- pelago likewise offer a fertile field for the fern collector, being rich in species of Hymenophyllum, and Trichomanes, Asplenium, Lomaria, as well as in Tree- ferns of the genera Oyathea and Alsophila. The one or more Surnatran Ferns yielding the singular styptic drugs brought to this country of late years under the un- couth names of Penghawa, Djambi, and Pakoe Kidang, would be of interest to cultivators from their beauty, and to pharmaceutists from their properties. Cibotium djambianum, Dicl'sonia chrysotricha, and two other species of Alsophila (A. lurida and tomentosa) have been mentioned as the sources of these drugs ; but very little is known respecting any of them, and more information is desired. Two singular and peculiar Ferns widely spread throughout this region are Tcenitis blechnoides and Osmunda Javanica, which, .although long known in herbaria, have not yet found a place in our living collections. The Moluc- cas and Celebes, especially, possess large numbers ; and among those in the former is the rare Cystodium sorbifolium, known only from a few imperfect spe- cimens from these islands, and from the island of Honimoe. Mauritius contains several which would be acceptable in our gardens ; but, with such an enthu- siastic explorer as Mr. Duncan in that island, it is to be hoped that they will not long be classed ;among our desiderata. I would particularly call atten- 28 FERNS : BEITISH AND FOREIGN. tion to Ocliropieris pollens, Antrophyum Boryanum, Ophioglossom palmatum. Cyathea canaliculata, and C. excelsa, as -well as Adiantum asari/olium and A. Mauritianum, — all found in that island, — are still scarce in, if not altogether lost to our gardens. I have already alluded to the paucity of species from Southern Africa at present in our gardens, although in the " Synopsis" of Pappe and Kawson, published in 1858, no less than 165 are described, and the localities where they are to be found given in detail. Not- withstanding that few of these are remarkable or striking in appearance, many would be prized on account of their small size and neatness, and they would be very suitable for Ward's cases. Even in European countries there are several Ferns which we do not yet possess in British gardens ; for instance, the Lastrea fragrans of the Arctic and sub- Arctic regions, said by Sir W. J. Hooker to be "one of the most beautiful of all ferns," is, as far as I am aware, known only from dried specimens ; while Asplenium fissum, found in several parts of Southern Germany and Italy, is rare even in herbaria, and altogether unknown in the gardens of this country. On the south-eastern confines of Europe, in the Caucasus, there is also the Woodsia Caucasica, an interesting species, closely allied to W. elongata, of Northern India. From the Western hemisphere, also, there are nu- merous fine species yet to be introduced. Fee's " Cata- logue of Mexican Ferns " shows that that country contains upwards of 300 not known in our gardens, though many of them would be very acceptable. Among these are several Tree-ferns, such as the remarkable Cyatkea Mexicana, found in the neighbourhood of HISTORY OP INTRODUCTION OF EXOTIC FERNS. 29 •Jalapa, Cordova,, and Oxaca, while the little tufted Schaffneria nigripes, found between Vera Cruz and Orizaba, would be an interesting acquisition to growers whose space is limited, being only three or four inches high, and having intensely black glossy stipes, and broadly obovate-cuneate fronds. There are also many very pretty species of Cheilanthes , — the Chei- lanthes speciosissima, with broad lanceolate multifid coriaceous fronds, measuring as much as two feet in length; and several very desirable species of Gleichenia, Trichomanes, and Hymenopliyllum ; of the latter genera, in particular, there are still many beau- tiful western species yet to be introduced. From the more northern countries of the American continent our hardy fern growers might obtain many additions. For example, it would be interesting to have the American Cryptogramme acrostichoides side by side with our British C. crispa ; and if to these the Hima- layan C. Brunoniana were added, we might then be able to ascertain whether they be really distinct species or merely forms of one and the same plant. The closely allied Pellwa gracilis, found in many parts of North America and also in Northern India, would be worth having on account of its remarkable resemblance to our C. crispa. Polystichum munitum, a Fern distributed over Western America, from California to as far north as Nutka, and, therefore, probably hardy, would be a fit companion for our own Polysti- chum Lonchites, though considerably larger. Lovers of golden Ferns would be glad of the Gymno- gramme triangularis, a species resembling Pellcea argentea in appearance, but much larger and covered with golden farina on the under- side ; and as this is 30 TEENS : BRITISH AND FOEEIGN. found as far north on the western coast as the Columbia river, it will, it may be presumed, prove hardy with us.. Did space permit, this list of desiderata from North America might be greatly extended; but I must pass on to the countries of the South, which offer a rich field to the fern-collector. In my enumeration of the Ferns of Panama, in Seemann's " Botany of the Voyage of H. M. S. Herald," I have described a very pretty Fern from Southern Darien under the name of GlypJiotcenium crispum, which would be an acquisition to those who grow Ferns in a natural manner, though not suited for pot culture. It is found on trees, from the branches of which its tufts of long and narrow wavy fronds hang down in a very graceful manner. In Darien, Panama, and the adjacent Pacific islands, also, there are several Tree-ferns which we have not yet got; such asHemitelia petiolata, a distinct species, with large pinnate fronds, having widely- separated petiolated pinnules; and Alsophila clongata, a very robust species. New Gra- nada, Venezuela, and other countries north of the equator, though explored by several collectors, would still yield a good many desirable novelties to our gardens. In the former country I may indicate the several species of the extremely curious genus Jame- sonia, with their very narrow, erect, rigid fronds, conti- nuously developing little orbicular, concave, imbricated pinnae, and densely clothed, while young, with fer- ruginous hairs ; and also Dryomenes Purdiei, a mag- nificent Fern with very deeply pinnatifid fronds from four to five feet long, having extremely broad segments, covered with numerous small sori, which may probably possess indusia ; but younger specimens than those in HISTORY OP INTRODUCTION OP EXOTIC PERNS. 31 my herbarium are required to settle this point. Ill- Venezuela there is the remarbable AmpJiiblestra lati- folia, a Fern resembling some of the larger species of Aspidium in habit and appearance, but having a line of confluent sori on the margin like the Pteridice, to which tribe it is generally referred, some authors retain- ing it under Humboldt's name, Pern's latifoliaj&nd also a species of Trichomanes of extraordinary size, T. Kun- zeamim, nearly allied to our own Irish species T. radi- cans, but with rather rigid fronds, from two to three feet in length. One or two species of Lindscea are also found in Venezuela, particularly the neat L. stricta, with fronds varying from pinnate to tri-pinnate, though most commonly bi-pinnate. But the head-quarters of the genus Lindscea in the Western hemisphere are Guiana, where is found the rare L. remformis* resem- bling in the general appearance of its fronds the well- "knownAdiantum reniforme}and. the yet to be introduced Gymnogramme reniformis of Brazil, a rare plant even in herbaria. The exceedingly beautiful L. trapeziformis,, which has bi-pinnate fronds two feet or more in height, is also found here, as well as in other parts of tropical America and the West Indies. I may remark that, notwithstanding that some of the loosely compiled garden catalogues in common us'e among gardeners mention as many as twenty-six species of this genus being in cultivation, I know of only two, and I have made many inquiries upon the subject. The genus contains upwards of sixty described species, dis- persed over the tropical and sub -tropical countries of * Lately introduced by Messrs. Backhouse of York, but yet rare. •32 FERNS : BRITISH AND FOREIGN. both hemispheres, and many of them would be highly prized by fern-growers. Amongst other Guiana Ferns worthy of notice there is one to which I would wish particularly to draw attention, not only on account of its singularity, but of the little that is known of it by pteridologists. I allude to the Dancea simplicifolia of Rudge, of which I have only seen two specimens, one in Rudge' s herbarium, and the other in Schomburgk's Guiana collection. In general appearance the sterile fronds of this Fern resemble those of Elaphoglossum lati/olium, being about eight inches in length (including the stipes) and of an ovate-lanceolate form, attenuated to the base, while the fertile ones are narrower, and still more attenuated downwards. Nor must I omit to notice the very remarkable Hewardia adiantoides of French Guiana, still very rare in herbaria. It would be a noble addition to our large species of Adicmtum, its fronds being two or three feet high, very broad, and irregularly bi-pinnate, with remote, alternate, petiolate pinnules from three to five inches long, and about two inches wide, and borne upon glossy black stipes. Closely allied to this is the Hewardia dolosa of Eastern Brazil, Surinam, and Ecuador, with much longer but comparatively nar- rower pinnules and rough hairy stipes. There is also in Dutch and British Guiana, as well as in Brazil (in the neighbourhood of Rio Janeiro), a species of the curious Schizceaceous genus, Actinostachys (A. pennula, Hook.), resembling the Ceylon A. digitata, already in our gardens, though extremely rare. While the beautiful Schizcea flabellum, with its fern-shaped fronds, cleft into two to form broad wedge-shaped segments, and upon stipes a foot or so high, is found HISTORY OF INTRODUCTION OP EXOTIC FERNS. 33 in British Guiana, and also on the banks of the Orinoco, Bio Negro, and Yapura rivers. Several other species of Schizaea are likewise worthy of a place in our gardens, such as the pretty Schizcea pectinata of the Cape of Good Hope, and Schizcea dichotoma, which is found not only in Guiana and Venezuela, but widely dispersed through the Pacific islands as far south as New Zealand, occurring also in Java, Mysore, the Mauritius, and other parts of the Eastern hemi- sphere. Allied to these, also, are the two Brazilian species of CoptophyUum described by Dr. Gardner, and likewise the Trochopteris elegans of the same author, all of which some pteridologists include under the genus Anemia, and perhaps rightly so with respect to the former, for they have the same relationship with true Anemia that Osmunda cinnamomea has with 0. regalis, their barren and fertile fronds being dis- tinct. Both species are found in the province of Goyaz ; one being named C. millefolium and the other C. buniifolium, from the general resemblance in the divisions of their barren fronds to the leaves of Achillea millefolium and Bunium. The Trochopteris elegans is an exceedingly curious little Fern, with flat, radiating fronds of a somewhat spathulate form but more or less five-lobed, the two lower lobes being deeper and bearing the sporangia, the entire plant resembling a rosette, and growing on rocks like a lichen. Dr. Gardner found it on the Serra de Nativi- dad, in the province of Goyaz. Amongst other Bra- zilian Ferns worth being looked after, I may mention two species of Antigramme — A. Brasiliense and A. Douglassiij the former having oblong-lanceolate fronds about a span long, tapering downward to a short 34 FERNS : BEITISH AND FOREIGN. stipe ; and the latter ovate fronds of the same length, but usually cordate at the base and upon long stipes. Lomaria zamioides of Gardner, a plant with a trunk four feet high, resembling a Zamia, found by Gardner in boggy places near the summit of the Organ Moun- tains, would also be a valuable addition to our small- growing Tree-ferns.* Brazil is rich in Tree-ferns, but only a few of them have as yet been introduced. I will mention only one or two. DicJcsonia Selloiviana, found 'on the Organ Mountains, is, like the Lomaria above men- tioned, remarkable for its resemblance to an extreme southern species, dried specimens being scarcely dis- tinguishable from the Dichsonia antarctica, though most probably if the two were cultivated side by side they would prove very distinct. Cyathea vestita and C. Schamschin appear to be very plentiful throughout Brazil, and both are very fine species, the former having a trunk from twenty to thirty feet high. The two species of Triclwpteris — T. excelsa and T. elegans — are also very graceful trees, found in Southern Brazil, and although the latter is included in the fol- lowing enumeration, it is still very rare in our collec- tions. Several special localities in Brazil may be men- tioned as abounding in Ferns, such as the Organ Mountains and St. Catherine's, in the east ; on the eastern slopes of the Andes, where at elevations of from fifteen hundred to four and five thousand feet, in some localities, they flourish in great luxuriance. At Tarrapota, in Peru, Dr. Spruce, in a diameter of fifty miles, collected no less than two hundred and * Fine plants of this Fern have been recently imported to this country by Mr. Low of the Clapton Nurseries. HISTORY OP INTRODUCTION OP EXOTIC FERNS. 35 fifty species, twenty of which were Tree-ferns, and many new and interesting species. Before leaving tropical America I must say a few words respecting the West Indies, • the Fern Flora of which is to a great extent identical with that of the countries on the Atlantic coast of South America. A tolerably accurate idea of the number of species indigenous to the West Indies may be obtained from Grisebaclr's Flora of the islands belonging to Great Britain, where three hundred and forty are described, and their particular localities noted. Out of these, two hundred and twenty will be found enumerated in the following pages as already in our gardens; and as our intercourse with most of these islands is now so frequent, and the voyage ac- complished with such rapidity, we may expect ere long to receive all the most striking types of the remaining ones. Indeed, the West Indian correspondents of the Royal Gardens at Kew, as well as those of several nur- serymen, and other private individuals, are continually forwarding Ferns to this country ; and under these circumstances I do not think it worth while to men- tion any particular species ; but it is worthy of remark that among our desiderata is the numerous group represented by Polypodium tricJiomanoides, Passing westwards to Ecuador and Peru, I might give a long list of desiderata, particularly of pretty little Alpine species from the Andes, belonging to Cheilanthes, Notholcena, Asplenium, and Polypo- dium, but want of space compels me to confine my remarks to a few of the most desirable ones. In his second century of Ferns, Sir W. J. Hooker has figured a beautiful Polylotrya, named P. Lech- D 2 36 TEENS : BRITISH AND FOREIGN. lermna, after its discoverer, Dr. Lechler. It has large, finely divided, somewhat membranaceous fronds, three or more feet in height, resembling a species of Darea, and thick scandent rhizomes. Cyathea micro- pliylla, fonnd by the same collector, and figured in the same work, appears to be a neat little Tree-fern, with stems four feet high and finely divided fronds, two or three feet long, ferrugineous from hairs on the under side. Some species of Gymnogramme are worthy of note, such as G. elongata, with narrow pinnate fronds a foot or more long, something like those of the well-known Notholcena trichomanoides, and clothed with copious longish hairs ; G. flabellata, the fronds of which are about a foot high, bipinnate, with dark shining stipes, and little flabelliform, dicho- tomously divided, green pinnules, and extremely neat ; G. incisa, which has bipinnate fronds a span or more high, and scarcely more than an inch wide, with the pinnules deeply incised. These Gymnogramms are also found in Venezuela, New Granada, and countries north of the equator, where there is also a remarkable scan- dent species, G. refracta, the finely cut fronds of which continuously increase to a great length, and ramble over the branches of trees. Our collections of Gleichenice- might be also enriched with several species from Peru and Chili, particularly G. simplex from the former, and G. pedalis from the latter. G. simplex having simple, pectinately pinnatifid fronds a foot and a half in length, with short stipes ; and G. pedalis fronds of the ordinary form, something like G. furcata, but smaller, neater, and more compact in its mode of growth. And, finally, the two singular Polypodice, with, dimorphous fronds, would be very pretty addi- HISTORY OF INTRODUCTION OP EXOTIC FERNS. 37 tions to our ferneries. One of these, Polypodium heteromorphum, Hook., was found by Dr. Jameson "upon the top of the mountain face of dripping rocks ; " and has simple fronds like those of Asple- nium Trichomanes, mixed in the same tuft with others which are repeatedly branched in a regular dichotomous manner like the Gleichenice ; while the other, Polypodium bifrons, Hook., found by the same botanist in Ecuador, growing on branches of trees partially immersed in water, has sterile fronds resem- bling oak leaves in their general outline, and narrow wavy fertile ones. To the creeping rhizomes of the specimens collected by Dr. Jameson there were attached curious bodies, resembling small potatoes . but these were most probably adventitious, and caused by some insect. Dr. J. W. Sturm, in his little work on the Fern Flora of Chili, enumerates one hun- dred and sixty-one species as found in that country and the adjacent island of Juan Fernandez ; but very few of these have as yet been introduced, though many of them would prove acceptable additions to our half-hardy collections. The numerous islands of the Pacific Ocean are, as a general rule, rich in Ferns, and worthy of being visited by a collector of living plants. The Hawaiian or Sand- wich Islands, for example, would afford three fine species of Cibotium. One of them, which has the stipes densely clothed with beautiful golden silky moniliform hairs, is so abundant that these hairs are collected as an article of commerce and are largely exported to California and Australia for the purpose of stuffing cushions, &c. ; Polypodium pellucidum, a creeping species, allied to our P. vulgar e, but differing in having pellucid strito 38 TEENS : BKITISH AND FOREIGN. between the fascicles of veins, and varying so mucli in the more or less compound division of its fronds, that one state of it was described as a distinct species by Sir W. J. Hooker, under the name P. myriocarpon ; Asplenium Sandwichianum, with large trip inn ate fronds three feet high, with numerous small segments, bearing some resemblance to a Mimosa leaf, and others too numerous to mention. The Galapagos, although not rich in Ferns, are worthy of notice, on account of a very rare and remarkable species, first described and figured by Sir W. J. Hooker, in the "Icones Plantarum," under the name of Acrostichum (Neuro call-is) aureo- nitens, and more recently in the fifth vol. of the " Species Filicum " as AcrosticJmm (Chrysodium) aureo-nitens. Judging by either of the sectional names, it might be supposed to have some resem- blance to the well-known AcrosticJmm aureum, but such is not the case, reticulated venation and appa- rent amorphous sori being the only characters that place it in that alliance ; in habit it is totally dis- tinct, just as distinct from Acrosticum (Chrysodium) aureum as Cetera cli officinarum is from Asplenium (Hemidictyon) marginatum. The plant has simplo barren and pinnate fertile fronds 6 to 10 inches in length, the whole plant being densely clothed with shining scales. To me its relationship seems to be with Hemionites vestita, a beautiful Fern of India, and also with another little-known species, the Gymno- gramme (Eugymno gramme) Muellerii, a native of north-eastern Australia, described and figured by Sir W. J. Hooker, in the fifth vol. of the " Species Fili- which also seems to me to be closely related to HISTORY OF INTRODUCTION OP EXOTIC PERNS. 30 Hcmionites vestita, but described as having free veins. Whatever difference then may actually be in the character of the venation of these three species there can be no doubt but that they are closely allied and constitute a very natural group. I have always considered that Hemionitcs vestita does not well asso- ciate with true Hemionites, but now, having found two companions for it, I view them as forming a natural genus, to which I apply the name Clirys- odium. I hope that ere long we may have the op- portunity of becoming better acquainted with them ; their silky appearance renders them worthy of being added to our living collections. In the Fijis again, Ferns form a conspicuous feature in the vegetation. During a visit of only six months, recently paid to these islands by Dr. Seemann, for the purpose of exploring them and investigating their Flora, he collected specimens of about 800 species of plants, a ad of these one-seventh were Ferns, very few of which are yet known in our gardens. A few of the desiderata are worth mentioning, particularly the graceful Todea Wilhesiana, found by the collectors attached to the United States' Exploring Expedition, and named by Mr. Brackenridge in compliment to Commodore Wilkes, who was in command of the expedition. It is spoken of by Brackenridge as the ' ' Little Tree-fern," and as being not more than three or four feet high ; but Seemann found it in the moun- tains of Somosomo, where it grows as underwood, attaining seven feet in height, and often with several crowns. The stem is as slender as a walking-stick, and the fronds bipinnate, and about two feet in length, with the ultimate pinnules thin, but not so delicate or 40 FERNS : BEITISH AND FOREIGN. so finely cut as T. hymenophyloides. Davallia Fejc- ensis is a species with, highly decompound fronds, a foot or so high, having the segments so narrow that they bear only a single sorus upon each. A species of Hemonites, H. lanceolata, and Syngramme pinnata, are found in these islands ; the latter having, on old plants, large pinnate fronds about one to two feet high, including the rather long stipes, the first simple lanceolate fronds from a foot to eighteen inches high, but it is questionable whether these simple fronds be not merely a state of the latter plant, for other species of Syngramme are known to have simple fronds as well as pinnate. Allied to Syngramme is the long and well-known Tcenites blech- noides, which has a wide geographical range, but is not yet introduced alive ; the form usually seen in herbaria from the Malayan islands has large simply pinnate fronds, with long tapering pinnae, like Blech- num orientale. There is also another Fijian Fern, desirable as much on account of its botanical character as from the singularity of its appearance, viz., Dididopteris angus- tissima, which grows epiphytically on trees, chiefly the Tahitian chestnut (Inocarpus edulis), in the manner of Vittaria, and has narrow, thin, grass-like fronds, varying from six inches to a foot in length. In all the Fijian specimens I have seen, the fructification is seated in a groove upon a vein running along the side of the midrib, and parallel with it, though in the generic character drawn up by Brackenridge, it is said to be normally in two rows, one on either side of the midrib ; but, as Brackenridge alludes to its being occasionally on one side only, I am not disposed to HISTORY OF INTRODUCTION OF EXOTIC FERNS. 41 consider it as a distinct species without further evidence, though it is worthy of remark that the specimens seen by that author were partly from the Samoan, and partly from the Fijian group ; and it is possible that the two forms are separated geographi- cally, as well as by their technical characters. Did space permit many others might be indicated — not only from these islands, but from other Polynesian groups ; though, as far as it is at present known, the Fern Flora is very uniform in species throughout. New Caledonia, the Soloman Isles, and others, have not, however, yet been well explored, either by botanical or horticultural collectors. As might be expected from the great intercourse that has been carried on of late years between this country and New Zealand, the greater part of the Ferns indigenous to that colony are now to be found in our half-hardy ferneries, only about 20 — a small number — out of the 120 species described by Dr. Hooker in his " Handbook of the New Zealand Flora," remaining to be introduced. One especially I should be glad to see in a living state : viz., the remarkable as well as handsome and very rare Loxsoma Cunninghamiiy found by Cunningham on the Keri Keri River, Bay of Islands, and by Sinclair on the Wangarei Eiver, in the Northern Island. This Fern possesses the habit of a Microlepia, and has broadly triangular decompound fronds, two to three feet high, glaucous below, with sori intermediate in character between Trichomanes and Davallia.* The Tasmanian Ferns are likewise nearly all intro- * This Fern was introduced, but has not become established. 42 TEENS I BRITISH AND FOKEIGN. duced; only one half-dozen out of the 52 species described by Dr. Hooker in his "Flora Tasmania" being unknown in our gardens, while of the Aus- tralian ones about a third are still wanting to complete our collection, and one of these is the extremely rare Platyzoma microphylla, found by R. Brown on the borders of the Gulf of Carpentaria during Flinder's voyage — an extremely neat little Fern, with rigid pinnate fronds a foot long, and hardly one-eighth of an inch broad, having minute oval pinnules, with revolute edges and powdery beneath, growing in tufts from short creeping rhizomes.* I have now traced the progress of the introduction of exotic Ferns to the gardens of this country, and shown that many novelties have yet to come. No doubt, more or less of them will from time to time be intro- duced, as they are eagerly sought after by nume- rous amateurs. Select private collections are thus formed, in many cases consisting of rare and unique plants ; but, in the course of time, changes in private establishments take place, and thus collections of Ferns get dispersed, and species are often lost to the country. It is, therefore, only to such public esta- blishments as that of Kew that we have to look to for the preservation of special collections. As there is no law or rule defining what kinds of plants should or should not be grown in public Botanic Gardens, the matter resting entirely with the Director or Curator, some families of plants are often more favoured than others, although all are of equal merit * Since the above was written about a dozen of the species named have been introduced, and will be found in the Appendix to the Second Edition. HISTOEY OP INTRODUCTION OP EXOTIC PERNS. 43 in a botanical point of view. To a certain extent, the Fern collection at Kew is a proof of this ; it so happens that both Sir W. J. Hooker and myself had an early predilection for Ferns, which has led to the gradual increase of the fine collection at Kew; and,, although I am now* incapacitated, by failing sight, from doing more in support of this collection, still, happily, it remains under the direction of Sir W. J. Hooker, who, doubtless, will not allow it to deteriorate, either in number of species or other- wise. One great means towards assisting in their preservation is continuing to view them as a scienti- fic collection. Scientifically-arranged collections are presumed to be the leading features of all Botanic Gardens. Unfortunately it is not the most showy or attractive. My long experience has shown me that as soon as a scientific arrangement in any family of plants is lost sight of, and showy cultivation made the first consideration, a rapid loss of species is the- sure consequence. For their proper maintenance it is most essential that the cultivator should view even the most humble species with a scientific and conservative eye. It is also much to be desired that an official rule should be made, requiring an in- ventory of the collections to be taken every few years, and the publication of a general catalogue ; or, in order to meet the various tastes of the public, separate- catalogues of special families, like the one I now publish of the Ferns, might be issued. * May, 186-1. 44 FERNS : BEITISH AND FOREIGN. II.— ORGANOGRAPHY. FOR the purpose of rendering the technical descrip- tions occurring in the following pages intelligible to those not well acquainted with botany, I have thought it necessary to devote a preliminary chapter to organo- graphy, being the explanation of the various terms in common use among pteridologists. I adopt this course in preference to giving an ordinary glossary, because I think a better idea of the structure of the plants, and the relation of one organ to another, and of the relation of the terms to the organs themselves, may be conveyed by it ; but for convenience of refer- ence I append an alphabetical list of the terms, paged so that they can be easily found in the explanatory chapter. In the generic characters I have endeavoured to avoid needless technicalities, though I have not attempted to frame them in what is commonly called a " popular " style, and I hope that with the aid of the following explanations, persons of ordinary abilities who have not made botany their study, will be able to understand them. In many cases, espe- cially in describing the form and shape of the fronds, the same terms are employed as in flowering plants ; but as now and then they have special significations, I have briefly explained all that occur in this work. Ferns (Filices) are flowerless plants, and form the highest order of the division of the vegetable kingdom termed Cryptogamia. Their most evident organs consist of the stem and the leaves, the OEGANOGEAPHY. 45 latter of which are always called fronds, and are variously traversed by veins, ramifying in a determinate manner in the different genera. Upon certain definite parts of these veins, generally on the under side of the frond, termed the receptacles, clusters or lines of free one-celled spore-cases (sporangia) are produced, or occasionally many-celled ones (synangia), and in these cases the reproductive spores are contained. The clusters are called sori. VERNATION. The word vernation, as employed by me, designates the mode of growth of Ferns, or, in other words, the manner in which their fronds are developed and connected with the stem. VERNATION is either — Articulated when the fronds are attached to the stem by a joint,, and leave a clean scar when they fall away ; or, Adherent when no such joint exists, and the bases are continuous with the stem. And it is either — Uniserial when the fronds are produced one after the other, in a, single lineal series, sometimes close together (contiguous], and at other times far apart (distant) ; or, Fasciculate when they surround a central axis, upon the top of which they form a crown. STEM. In a large number of Ferns the stem is not at first sight very evident ; and even when plainly visible, it is frequently confounded with the root by the unlearned (as, for example, the underground stems of Pteris aquilina) ; but in others, as in Tree-ferns, it is very marked. It is an organ of considerable importance for classifying purposes, and often affords valuable distinctive cha- racters. The principal modifications of the stem are the — Rhizome, a brittle, fleshy, prostrate stem, producing roots along its. under side, mostly growing above ground (epigceous), and then furnished with scales (squamose), but occasionally under ground (hypogceous), and then destitute of scales. It 46 FERNS : BRITISH AND FOREIGN. varies greatly in length, and is either simple or branched ; when very short and branched it forms tufts (ccespitose), and when very long (surculose) it usually climbs on trees (scandent). Very rarely it is erect (subfrutescent). Its point of growth is always evidently (often considerably) in ad- vance of the undeveloped fronds ; and the fronds themselves are produced singly from special, more or less distant, points on its sides, termed nodes, at which they are arti- culated. Sarmsntum, a tough slender running stem, rooting like a rhizome, and either epigaeous or hypogaeous, but differing in having the bases of the fronds adherent and continuous with it, and in its point of growth being coincident with, or scarcely ever in advance of, the undeveloped frond. Caudex, an erect or reclining (decumbent) stem, either simple or tufted (caspitose), through the growth of offsets, or rarely sending out long running shoots, which root at their ex- tremity (stoloniferous). It is often very small, scarcely rising above the earth, but generally more or less elevated, and sometimes forms a cylindrical trunk (arborescent), oc- casionally 50 or more feet high, which, in many species, is thickened by the growth of numerous aerial, outgrowing, wiry roots. And it bears a crown of usually adherent fronds, developed in a spiral series, upon its apex. FHONDS. The fronds of Ferns are either barren or fertile. In the great majority the latter do not differ very much from the former, though they are generally rather narrower in all their parts. But some- times they are very evidently different on the same plant, the barren presenting the ordinary leafy appearance, and the fertile being decidedly contracted, occasionally so much so that the leafy part is entirely absent, or in some the two kinds are combined in the same frond, the fertile portion being contracted, and the barren leafy. When young the fronds are involutely coiled, in the manner of a watch-spring, and gradually uncurl during the period of growth (circulate) ; rarely straight, as in Opliioglossece. OEGANOGEAPHT. 47 Fully developed fronds vary in size from less than an inch to 15 or 20 feet in length, and from a line, or even less, to 10 or 15 fee* in breadth. They also vary in form, in circumscription, and in texture ; and they are either furnished with a leaf-stalk (stipes) or are leafy to the base (sessile). In describing the form, circumscription, texture, and surface of the fronds of Ferns, the same terms are' employed as in the case of the leaves of flowering plants. They vary from simple entire to decompound-.multifid. In compound fronds the primary divisions are termed pinnce, and when more than once divided, the ultimate ones pinnules ; and the terms applied to simple fronds are equally applicable to these divisions. The divisions or branches of their stipes also are termed the rachis. Their texture is very different in different species. Some being thin, membranous, and even pellucid, while others are thick and coriaceous, or fleshy, rigid or flaccid. The surfaces of the fronds are either quite smooth, or furnished with different kinds of hairs, glands, or scales (the latter have received the name of ramenta, and are generally membranous and deciduous), or they are covered, particularly the under surface, with white or yellow farina. The plants called Fern Allies differ entirely in habit and mode of growth from true Ferns ; that the word fronds is not applicable ; but as the genus Selaginella is called " fern-like plants," I there- fore apply the term "frondules" to the species with distinct stems, and to the main branches of the surculose species. VEINS. In Ferns the mode in which the veins are disposed in the sub- stance of the fronds, or the venation, as it is termed, is of more importance than in flowering plants, the characters relied upon for distinguishing the genera depending more or less upon it, and there are numerous terms applied to it. The midrib of simple fronds, or of the pinnse or pinnules of compound fronds, is called the costa, and is in the former a con- tinuation of the stipes, gradually decreasing in thickness towards the apex, or altogether disappearing (evanescent), and in the latter 48 FERNS : BRITISH AND FOREIGN. a continuation or branch of the ultimate rachis with which it is either adherent or articulated. It is generally central ; but is sometimes excentric, or even quite on one side (unilateral), or some- times there is no costa at all. From the sides of the costa veins are produced at more or less distance from each other, generally equal on each side, except when the costa is excentric or the frond or segment has a radiating axis. The direction of the first or primary veins is, as in the leaves of other plants, towards the margin and apex of the frond or segment, forming a more or less acute or obtuse angle, or sometimes nearly a right angle with the costa. In describing venation the words veins, venules, and veinlets are employed, each successive one of which is intended as a diminutive of the preceding ; " veins " being applied to the first ramification of the midrib, "venules" to the branches, and "veinlets" to the branches of the venules. Some fronds have veins only, others, veins and venules, and others again all three. Terms are occasionally employed to express the relative distinct- ness of the venation, particularly when any marked peculiarity exists : thus it is said to be — Elevated, or external, when they are so thick that they are readily seen and felt on the under surface of the frond ; and — Internal when very much sunk in the substance of the frond. The primary veins are — Costceform when very strong and well defined, more or less re- sembling the costa in general appearance ; Undefined when of the same size as and not distinguishable from the venules and veinlets ; and — Evanescent when they gradually disappear towards the margin. Veins are spoken of as — Free when each vein proceeding from the midrib, however much it may be divided, is entirely unconnected with the neigh- bouring ones ; and — Anastomosing when the venules of one vein are in some way con- nected with those of the next. A fascicle comprehends a single vein with all its venules and veinlets. OEGANOGRAPHY. 49 Free veins are — Simple when each vein proceeds from the costa to the margin without branching (83). Forked when they divide at an acute angle into two or more branches after leaving the costa (51). Simply forked, or dichotomous, when the division is into two branches (96). Pinnately forked when the primary veins are scarcely defined, and branch several times one after the other on both sides (75). Pinnate when the primary veins that run from the costa to the margin are distinctly defined, and produce venules in regular order on both sides, so that the fascicles have a feather-like appearance (121). Radiate when the veins spread out from a definite point at the base of the frond or segment (93). The simplest form of anastomosing venation is when the apices of the veins are combined or connected by means of a marginal vein (113). In the more complicated forms it is spoken of as — Angularly anastomosing when the venules of one vein join those of the next, and form an angle at their point of junction (65) ; when the angle is very acute the term acutely anastomosing is employed, or sometimes called cathedrate. Arcuately anastomosing when the venules of one vein join those of the next, and together form an arch or curve (63). Transversely anastomosing when the venules of one vein join those of the next, and together form a nearly straight line (104). Distantly anastomosing when the venules are parallel with the costa, close together, and joined at long intervals by short cross veinlets. Compoundly anastomosing when the venules are irregularly con- nected in a more or less net-like manner, and have variously directed free or conniving veinlets in the areoles (21-28,43). Reticulated when the veins, venules, and veinlets are all connected together in a more or less net-like manner : uniform is used in reference to reticulated venation when there is no apparent difference between the veins, venules, and veinlets (31, 55). 50 TEENS : BRITISH AND FOREIGN. Areoles are the spaces formed by the anastomosing of veins, and are of various shapes and sizes : those next the costa are called costal areoles. In speaking of the venules of forked and pinnate veins it is- sometimes necessary to indicate a particular one in the fascicle : thus, the — Anterior venules are those on that side of the vein next the apex of the frond or segment ; and the Posterior venules those on the opposite side farther from the apex. Venules and veinlets are likewise said to be — Excurrent when directed towards the margin of the frond or segment ; and Recurrent when directed from the margin ; And their apices are said to be Clavate when thickened like a club. PHUCTIFICATION. As a general rule, what is called the fructification of Ferns is seated on more or less regularly arranged points or lines on the under surface or margin of the fronds, and is usually of well- defined form. There are, however, some variations from this. For example, in Acrosticliea it either covers the whole under surface of the fronds, or is in irregular undefined patches, and in some other cases, as Botrychium, Osmunda, &c., where the fertile fronds are- much contracted^ it assumes a spike-like or racemose form. The terms used in describing the fructification may be classed under four heads : — 1st. Those relating to the receptacle ; 2nd. those relating to the sporangium and synangium ; 3rd. those- relating to the sorus; and 4th. those relating to the indusium. 1. Receptacle. The receptacles are the sites upon which the sporangia are seated,, and are generally either thickened points on, or long thickened portions of, some part of the venation. In position they are — Terminal when on the points of the veins or their branches (5, 7). Basal when close to the costa (1), ORGANOGRAPHY. 51 Axillary when on the point where the veins fork (131). Compital when on the angular crossings or points of confluence of two or more venules or veinlets. Medial when in none of the above positions, but some intermediate part of the veins or the branches (21, 28). They are superficial, or immersed in the substance of the frond, or elevated above its surface, and then columnar (plate I. fig. 9) or globose. In form they are — Punctiform when small and dot-like. Elongated when long and line-like. Amorphous when of no denned form (46). 2. Sporangium. The spore-cases, or sporangia, are the organs which contain the reproductive spores, and are borne in masses upon the receptacles. They are thin and transparent, or horny and opaque, unilocular jvnd globose, oval or pyriform, usually pedicellate, which is articulate, but sometimes sessile, and either furnished with a more or less complete articulated elastic ring (annulate) (plate I. fig. 1), or destitute of a ring (exannulate) (plate I. fig. 4). In annulate sporangia the ring is said to be Vertical when it rises immediately from the apex of the pedicel (of which is a continuation), and passes vertically over the apex of the sporangium (plate I. fig. 1). Horizontal when it passes horizontally round the sporangium either at or about its middle (plate I. fig. 2), or at the apex (apical) (plate I. fig. 3.) Ollique when it has neither of the above directions, but passes round the sporangium in some direction intermediate between them. When the sporangia arrive at maturity and are under certain favourable conditions as to dryness, the elasticity of the ring causes them to burst open with force and sound sufficient to be heard, and this takes place in a direction at or very near to a right angle with the direction of the ring. In exannulate sporangia the opening takes place by a simple slit or pore (plate I. figs. 4 and 5). E 2 52 PERNS I BRITISH AND FOREIGN. Synangium* The synangia are formed by the union of a greater or lesser number of exannulate sporangia, arranged side by side, forming a series of cells, disposed in a circle, or in two rows side by side, united in one mass, which either remain united (plate I. fig. 5), or separate longitudinally in two valve-like lobes (plate I. fig. 6). The cells open for the escape of the spores by a slit on their inner side or by a pore at their apex. In Lycopodiaceae and Marsileacese there are two kinds of sporangia, the one containing numerous small spores, the other only a few — considerably larger. Some authors consider them to represent different sexes, and therefore named the first Antheridangia, the other Oophoridangia. The large spores are known to vegetate, and some say the small ones also ; the large ones are called Corpuscules. In the genus Marsilea the sporangia are called conceptacles, because they contain free vesicles of two kinds, one containing small spores, Antheridangia, the other large ones, Oophoridangia. 3. Sorus. The sori are the masses of sporangia borne upon the recep- tacles, and are either naked or furnished with variously shaped hairs and scales, or with membranous or rarely coriaceous covers of various forms (indusia) ; their form and position correspond with and are dependent upon those of the receptacles, which are their foundations. Thus, when the receptacles are punctiform, the sori are always round (5) or globose, while elongated receptacles bear sori of many forms, oblnng ovate, oval, elliptical, arcuate, linear (50), reticulated (54), &c. When situated on the margin of the frond or segment (marginal), a little wiihin the margin (antemarginal), somewhere between the margin and the midrib (intramarginal), close to the midrib (costal or basal), or sometimes on a pedicel, and pro- jecting slightly beyond the margin (exserted or extrorse} (73). In some cases they are irregularly scattered, but in others they are arranged either in rows (serial) (7) or in continuous lines, and when these diverge at an angle from the midrib they are said to be oblique (110) ; und when parallel with either the margin or the costa, transverse (96 and 100). As a general rule, each sorus is distinct and well- OEGANOGEAPHT. 53 defined, but in many cases the receptacles are so very close to- gether that one sorus runs into another (confluent], or sometimes the receptacles themselves are joined and form a more or less perfectly united simple sorus, or when not perfectly joined (as in Cryptogramme and Platyloma) a compound linear sorus. 4. Indusium. As stated above, the sori of some ferns are naked while those of others are furnished with a kind of cover, to which the name indusium is given by some authors, and involucre by others. The indusia present many well-marked forms, and often afford valuable characters for distinguishing genera, though they are by no means constant. Three kinds are distinguishable : special, accessory, and universal. True or special indusia are of a cellular membranous nature, and are produced from the receptacles to which they are attached in different ways. In some cases they are in the form of an orbicular disk, and then rise from the centres of the receptacles to which they are attached by their own centres, their edges being free all round ; this form is called peltate or central (plate I. fig. 7). More frequently, however, the indusia are more or less elongated, and are then attached to the sides of the receptacles (lateral) (plate I. fig. 8). In this case their attachment is either on the side next the costa (interior), or on that next to or at the margin (exterior), and is either by a point or sinus on their side, in which case their form varies from reniformto oval and oblong, or it is by the entire length of one side, when they are linear (110). Their surface is flat (plane), arched (vaulted), or hood-like (cucullate), and their edges are either entire or variously laciniated or fringed. Besides these two modes of attachment, there is a third kind where the indusia are attached all round the base of the receptacle, and they are at first globose and entire, but ultimately their apex opens, and then they assume a cup-like (calyciform) form with the margin more or less entire (plate I. fig. 9) ; sometimes the attachment is only half round the receptacle (semi-calyciform). Accessory indusia, sometimes in addition to the true indusia, portions of the margin of the frond are changed in texture and form, what are here termed accessory indusia, and which resemble the true indusia in appearance. These connive more or less with 54 FERNS : BRITISH AND FOREIGN. the true indusia, which in these cases are always attached on the interior side of the receptacles, and the two combined indusia form continuous or interrupted grooves, or urceolate, bilabiate, or tubulose cysts, open exteriorly and containing the sporangia (plate I. figs. 10 and 11). Universal indusia occur in cases when the segments of the fertile fronds are contracted. They consist simply of the margins of the segments being more or less changed in texture, and rolled inwards so as to include all the sori upon the segment (plate I. fig. 12). There is also another kind of indusium, called " indusoid scales ;" they only occur in a few species of the division Eremobrya. In Pleopeltis this consists of orbicular, peltate, glistening imbricate disks, covering the sporangia ; in Hymenolepis they are very thin and membranous ; in Schellolepis they are very irregular in form, and seem to be imperfect sporangia ; their deformity being caused by the excessively crowded immersed sporangia ; they are also found in Tcenitis and Vittaria, and have received the name of paraphyses. I however do not use this term in describing those genera. The orbicular disks of Pleopeltis, however, seem to be more special organs, particularly in the smooth-fronded species. I liave now explained the terms of the chief organs and structure of Ferns made use of for their classifi- cation. I fear a beginner will say it is quite enough to deter any one from entering upon the study of Ferns ; but he should bear in mind that it is quite as impossible to read a language without first learning the alphabet as to understand botanical descriptions without first mastering the technical terms employed in them. He will be further impressed with the difficulty of study when he finds that the very first point of inves- tigation is to determine whether the fern before him has or has not a ring to its spore-cases. He presumes that a microscope is required to determine this first starting-point ; but such is not actually the case, for with the aid of a pocket lens he will be able to detect the presence or absence of a ring, and as annulate OKGANOGRAPHY. 55 and exammlate Ferns in cultivation in this country are in proportion to one another as one to forty-five, he may soon become aware that the great majority of Ferns belong to the annulate section. But the best way for a beginner is to procure a few correctly- named species of each tribe, and carefully compare them with the characters given in the following pages. He will soon overcome the dread of technical phrases, and before long will be able to refer his unnamed species to their respective tribes and genera. EXPLANATION OF THE PLATE.

ON THE GENERA OF FERNS AND THEIR CLASSIFICATION. flTEE systems for the classification of Ferns are ••- almost as numerous as pteridologists themselves; indeed, nearly every author, from Linnaeus downwards, who has written upon the subject, has propounded his own views, and these have generally differed "both from his predecessors and from his contemporaries. But the point upon which pteridologists appear to differ most, and on which their only agreement seems to be an agreement to differ, is the definition of genera and their limits. I say emphatically appear to differ, for in the works of those most at issue, the differences are not so much in the limits of the groups themselves as in the relative importance assigned to them. For example, while some, as Presl, Moore, and myself, break up the old Linnsean genera, Poly podium, Aspi- dium, &c., into a greater or lesser number of smaller genera, others, as Hooker and Mettenius, prefer ad- hering to the Linnaean genera, without greatly altering their characters, and adopting the modern generic names as sectional ones for such divisions as they find themselves compelled to make. It would occupy too much space to enter fully upon this subject, and I must leave it for a more extensive work upon the genera of Ferns, long contemplated by me,* con- tenting myself here with a brief mention of the organs more or less employed by pteridologists in establish- ing and classifying genera. * See "Historia Filicum/'— Macmillan & Co. 1875. GENERA OP FERNS AND THEIE CLASSIFICATION. 57 An examination of the works of Linnaeus shows that he was acquainted with about one hundred and eighty species, and these he classed under eleven genera (viz., Osmunda, Onoclea, Acrostichum, Hemionitis, Poly podium, Asplenium, Pteris, Blechnum, Lonchitis, Adiantwn, and Trichomanes) , which were founded upon purely artificial characters, derived solely from the shape and position of the fructification. This system was amply sufficient for the limited number of species then known • indeed? the proportion of genera to species was much larger in Linnaeus's days than in our own; but when the number of species had been greatly augmented, it became obvious that, in order to avoid genera of unwieldy dimensions, if not for other reasons, addi- tional characters must be sought for ; and these have gradually been introduced. It is a remarkable fact, however, that although the number of species now known exceeds by about twenty-fold that known to Linnaeus, it is quite possible to arrange them all under the eleven genera established by that author. After the time of Linnaeus, the first additional organ relied upon for generic characters was the indusium, which was employed by Sir J. E. Smith and Pro- fessor Roth, and afterwards more fully by Swartz, who divided the twenty-five genera known to him into " naked " and ' ' indusiate." Linnaeus noticed the fact of the sori following the course of the veins in his character of Hemionitis, but, in 1810, Kobert Brown first specially employed characters taken from the position of the sori upon the veins. This was the next important step in advance. The same learned botanist was also before anybody else to point out the im- portance of venation as an aid to classification, but <58 FERNS I BRITISH AND FOREIGN. the credit of being the first to employ characters from venation upon a large scale is due to Professor Presl, who,, in 1836, published his celebrated "Tentameii Pteridographise," where he described one hundred and fifteen genera of Polyp odiacese alone, in the characters of all of which the venation holds the most prominent place. Several years before seeing Presl' s "Tenta- inen," I had been engaged in working out, and had completed, a treatise upon the same subject, which, T/ith a few necessary alterations in nomenclature, I afterwards published.* My views for the most coincided with those of Presl, but I had paid more attention to forming natural groups and bringing together species agreeing in their mode of growth, •and vegetative organs; for it appeared to me that pteridologists did not give sufficient importance to that point, and even now it is not taken into considera- tion as much as it deserves to be. With the exception of my own more recent efforts to obtain characters from the mode of growth presently to be explained, the only further suggestion of any importance remaining to be noticed is that of M. Fee, who, in his work on the Polypodiacece, introduced characters taken from the form and structure of the sporangia, the number of articulations in their rings, and the form of their spores. The form of the sporangia, and direction of their rings, had previously been adopted by Presl and myself for distinguishing the main orders or sub-orders of Ferns, and I, in common with all modern pteridologists, still rely upon those organs for that purpose ; but I cannot consent to their introduction into generic and specific characters, as proposed by Fee. Even were the dif- * Hook. Journ. Bot, 1841. GENEKA OF FERNS AND THEIR CLASSIFICATION. 59 ferences pointed out by Mm constant, which they are not, the organs themselves are so minute that the study of Ferns would be impeded rather than facili- tated by the laborious microscopic examination de- manded. The spores also vary at different ages, and are thus apt to mislead. No practical advantage is gained by the introduction of such characters ; and natural groups and alliances can be established without them, by employing such tangible characters as do not require much aid from the microscope for their observation. I now come to consider the characters taken from mode of growth. My long connection with the Eoyal Botanic Garden at Kew, where an unrivalled collection of Ferns exists, has given me abundant facilities for the observation of growing plants, and after an atten- tive study and close examination of many years I am induced to attach a higher value for systematic pur- poses to the different modes of growth than my con- temporaries may be disposed to do. My views upon this subject were first published in Seemann's "Botany of the Voyage of H.M.S. Herald" (p. 22G), and subsequent observations have but confirmed them. Ferns present two very distinct modes of growth, the one of which I term Eremobrya, and the other Des- mobrya, and these are comparatively as distinct as the primary divisions of flowering plants ; but I do not, as has been suggested, consider that there is any analogy between the structure of the stems of Eremobrya -and Endogens, and Desmobrya and Exogens, that their respective modes of development are identical, or that Eremobrya and Desmobrya are of equal value in a general systematic point of view with Exogen and 60 FERNS : BEITISH AND FOREIGN. Endogen. The terms equivalent to the two latter are Pleurogen and Acrogen. In Eremobrya the fronds are produced singly from the sides of a rhizome, which has its growing-point always evidently in advance of the young developing frond. Each frond springs from a separate node, more or less distant from its neighbour, and is there articulated with the rhizome, so that when it has passed its maturity it separates at the node, and leaves behind a clean concave scar. The rhizome is solid, fleshy, and brittle, and when young always- densely covered with scales (excepting in hypogeous rhizomes), which seldom, except in the very few scaly- fronded species, extend higher than the node ; but it varies in some respects, being in some cases long and slender, and either simple or branched, and in others short and thick. The essential distinction between Eremobrya and Desmobrya rests in the fronds of the- former being articulated with the axis, while those of the latter are adherent and continuous with the axis. In Desmobrya the fronds are developed in two modes. In a large number of Ferns belonging to this division they come out from the apparent apex of the axis in a spiral series, and form a fascicle or corona. In this case the axis or stem is an erect or decumbent caudex, very variable in size, being sometimes scarcely elevated above the ground, and sometimes, in extreme cases, rising to the height of fifty or more feet. Almost an equally large number, however, have their fronds de- veloped in a single alternate series, and their stem forms a sarmentum, in which the point of growth is in most cases scarcely at all in advance of the develop- ing frond, and would appear to be coincident with GENERA OF FERNS AND THEIR CLASSIFICATION. 61 it, though sometimes the prelongation is evidently in advance, and then the mode of growth appears to agree with Eremobrya ; but the non-articulation of the stipes at once distinguishes it. Whatever the character of the stem of Desmobryous Ferns, it is always formed of the united and adherent bases of the fronds, and increases by the successive evolution of fresh fronds, each succeeding one of which is produced on the interior side of the bases of the preceding ones. All Ferns are referable to one or other of these two divisions, and in general the difference between them is readily seen, particularly when living plants are examined ; but, as in all attempts to generalize from special organs or structures, there are exceptions. For example, in Elaphoglossum the fronds are neither strictly adherent nor strictly articulate, but have a swelling some distance up the stipes, at which point, though there is no change in structure, the vascular bundles are so weak that the fronds ultimately sepa- rate there; and hence I regard the genus as an aberrant form of Desmobrya (?). In Woodsia, again, the stipes has an elevated articulation ; but the axis is a caudex formed of the adherent bases of the stipes, and this, together with its fasciculate frond, indicates its true affinity to be in Desmobrya. A few also occur, as in the section Ctenopteridece of the tribe Polypodies, in which the articulation is obscure, and a careful examination is required to detect it. Notwithstanding these few exceptions, there can be no doubt that the two modes of growth above de- scribed are widely distinct, and the two groups into which Ferns are thereby divided are quite distinct in habit and appearance. The plants too seem to be 62 FERNS : BRITISH AND FOREIGN. endowed with very different natures, for the vitality and tenacity of life is much greater in the Eremo- bryous than in the Desmobryous division ; and it is not a little remarkable that so far as observations upon cultivated plants enable me to ascertain, the latter are freely reproduced from spores, while the former are in proportion rarely reproduced by that means. In confir- mation of this tenacity of life in Eremobrya I may men- tion that in importations of Ferns from distant countries those belonging to that division generally arrive in a living state, while Desmobryous ones, particularly those with sarmentum, are often killed in the transport. I have now briefly reviewed in chronological order all the organs or structures upon which pteridologists rely for the formation of genera. Unfortunately, scarcely two can be found who agree as to the principles upon which genera of Ferns should be founded, or as to the value of the several organs for generic purposes. Some apply to Ferns the princi- ples which characterize the genera among flowering plants, depending for the most part upon characters taken from the organs of reproduction. Others place great reliance upon the different modifications of venation ; whilst I believe I stand alone in endeavour- ing to obtain natural genera, that is, genera having species associated by general habit and appearance, and by employing auxiliary characters taken from the modes in which the plants grow. Habit is not excluded from generic characters of flowering plants ; indeed numerous instances might be quoted in which it is allowed by eminent botanists to constitute the chief distinction between allied genera, and by intro- ducing it into the characters of Fern genera, more GENERA OP FEKNS AND THEIR CLASSIFICATION. 63 natural groups aud sequences are obtained than by a, strict adherence to the artificial characters afforded by the fructification and venation. Among Ferns no single organ alone affords characters sufficient for general systematic purposes. Were the principle- upon which Linnasus acted — that is, a strict adherence to the fructification alone — applied in its integrity to the enormous mass of Ferns now known, — and it- would be quite possible to do so, the most incongruous plants would be associated under one genus, and the magnitude of the genera would be quite overwhelming. The same would be the case were venation alone or habit alone to be taken into consideration. In somo instances, however, a marked difference in one set of characters indicates well-defined groups; but as a general rule a combination of differences in two or more sets is requisite. Great difference of opinion exists as to what is and what is not a genus ; but so long as plants are distributed into well-circumscribed groups of not too great an extent, it appears to me that it is a matter of little importance whether those groups be termed genera, sub-genera, or sections. For my own part I prefer regarding them as genera. It has not been without due consideration that I have- arrived at this conclusion. It also saves a great deal of unnecessary trouble, both in speaking and writing about Ferns, it being more easy to say and write Elaplioglossum conforme, than Acrostichum (Elapho- glossum) cow forme, or Gymnogramme tomentosa, than Gymnogramme (Eugymnogramme) tomentosa, &c. Also by studying the character of the smaller groups indi- vidually, and treating them as genera, their nature is- at once brought to the mind, without having to think 64 FERNS I BRITISH AND FOEEIGN. of their association with a host of species of quite dis- tinct characters. It also leads to investigation, and, accordingly, to a better knowledge of the structure of Ferns. With regard to the characters that define the limits of species, as much uncertainty prevails amongst authors as with genera. This is owing to several causes ; such as many species being normally hetero- morphous, presenting at the same time different forms, which again vary at another period of growth ; and in many instances authors have described the different states as distinct species ; and in some cases different fronds of the same plant, and even portions of the same frond, have been placed under separate genera. It also frequently happens that two or more presumed species present so many intermediate gradations of form, that only the most extreme states appear suffi- ciently distinct to warrant their adoption as species, the numerous intermediate forms seeming to set specific distinctions at defiance. It therefore becomes a question what is the limit of form or of structure that constitutes a species. Generally understood, a species is an organized structure endowed with an essence or quality peculiar to itself, and possessing the power of multiplying and transmitting its type to new genera- tions without change, ad infinitum. Admitting this definition as correct, it seems to be beyond human power to ascertain whether the serial gradations of form are genuine descendants of original creations, or only deviations from one original, brought into exist- ence during the lapse of ages by the different climatic and local influences they have been subjected to. It is well known that phsenogamous plants assume differ- GENERA OP FERNS AND THEIR CLASSIFICATION. 65 ent forms and aspects, effected by the agency of man and by various natural causes ; the difference from the original types being often so great, that if evidence of the change were not on record, the botanist of the present day would be justified in describing them as distinct originally created species. With Ferns we possess but little evidence of new forms having come into existence, the chief examples being found in sev- eral intermediate states in the genus Gymnogramme, which of late years have made their appearance in gardens, and seem to have as good right to be re- garded as species as the original typical forms first known. If such changes do actually take place, and we are to deduce from them that races of intermediate forms originate in the progress of time and through the causes above alluded to, then great difficulty must attend any attempt to define species of Ferns. This is espe- cially applicable in determining species from extensive suites of herbarium specimens. The number of species will be diminished or increased in accordance with the botanist's idea of specific differences : he will either amalgamate a number of allied forms under one specific name, or separate more or less of them as distinct species. On inspecting living examples of allied forms, the latter view seems to claim adoption ; for although words often fail to convey the differences between individuals, still the eye readily detects them, and knowing that each maintains its own peculiar phase or habit from year to year, the scientific observer con- siders himself justified in naming them distinct species. It is a botanical rule to retain the names under which species are first described, whether continued in their original genus, or in whatever genus they may after- 66 TERNS ! BRITISH AND FOREIGN. wards be placed. But as many species of Linnseus, Swartz, and other old, as well as modern authors, are but indifferently described, many being derived from imperfect specimens, and with nothing but the meagre description left us for their identification, it frequently happens that some modern author detects, or supposes he has found out, that the new species of his contemporary is one of the Linnaean or Swartzian doubtful species, and faith in his decision being admitted, familiar names become changed, thus bur- dening the science with additional synonyms, and rendering it in many cases impossible to reconcile one author's views with another. As an instance of the different views of authors on the identification of species and their synonyms, the genus Asplenium is a good example, it having within these few years, and near about the same time, been revised by Dr.Mettenius, Sir W. J. Hooker, and Mr. Moore. The two latter had the advantage of profiting by Dr. Mettenius's views, but in a great many cases I find it quite impos- sible to reconcile or agree with the views of either. As an example of the different views, I will cite the plant known in gardens for the last forty years by the name of Asplenium Shepherdii. The above-mentioned authors place it as a synonym, each under a different species and with different synonyms. To show the impossibility of reconciling one with the other, it will be sufficient to notice that in the Index Filicum it is found as one of twenty-three synonyms under Dipla- stium ro.dicans. Believing as I do that these synonyms represent several distinct species, and the plant in question being one of them, I deem it best to retain it under the name it has been so long known by, and GENERA OP FERNS AND THEIR CLASSIFICATION. 67 which is very well represented in "Lowe's Ferns/' vol. v. p. 47. These observations briefly explain a few of the causes of the plurality of names possessed by most Ferns, also the difficulty of arriving at satisfactory conclusions respecting their generic and specific distinctions, affording little hope of an early unanimity amongst authors, and fully justifying every one who has studied Pteridology in giving his own views. This being the case, I have to explain that, some important changes in the relative position of tribes and genera have been made in the following enumera- tion, in order to bring natural allied genera together ; thus Oleandra and the articulated Davallia, are now placed in Eremobrya, which is their proper place. The tribe Aspidiece I now make a section of the tribe Phegopteridece, their former separation being entirely dependent on the presence or absence of indusia, an organ not to be depended on in this tribe, when in many cases I am doubtful even of its value as a generic distinction, such as between Dictyopteris and Aspidium, Goniopteris and Nephrodium, PJiegopteris and Lastrea, these genera containing species perfectly analogous to one another in general habit. The fugaceous nature of the indusium also makes it an organ of less import- ance than it is generally considered. In many species it is very small, and is soon lost or obliterated by the swelling of the sporangia; it is therefore only by watching living plants while the sori are yet young, that many species can be proved to be indusiate or non-indusiate. I have long been dissatisfied with the position of Hymenophyllece as a section of the tribe Dicksoniece, it F 2 FERNS I BRITISH AND FOREIGN. having no natural affinity with the typical representative of that tribe. I have, therefore, characterized them as a distinct sub-order. Mettenius, in his work on Hyme- nophyllece, published in 1864, removes them from the position they have hitherto held between Gyathece and Gleiclienicce, and places them before Polypodiece, as- signing to them the lowest rank amongst the Ferns ; in their downward relationship they would border an mosses. It, however, appears that as far back as the year 1828 the elder Reichenbach regarded the Hy- menoplujllcce as the lowest group of Ferns, and indi- cated their relationship to be with Hepaticce. But to •discuss the views of these two authors on this subject would require more space than this work will allow. These, with a few others, are the principal changes ^1 have introduced; more might be made, but as, without being accompanied with full explanations showing my reasons, they might be considered un- necessary, I defer my views on the subject for -another and more general work on the genera of Ferns, already alluded to. The limited size of this book does not permit me to give descriptions of the species; but in order to assist in referring species to their respective genera, I have given the general characters and a woodcut of each genus, and also the principal synonyms, with refe- rences to one or more published figures. The native •country of each species I have given only in its widest sense, as many species have a wide geographical distri- bution, and to state their precise localities would require much space, and is the less necessary, as the special localities of each species are given by Sir W. J. Hooker in his great work, the " Species Filicum," now happily GENERA OP FERNS AND THEIR CLASSIFICATION. 69 brought to a close after twenty years' arduous and patient study. Another work has also been compiled during the last few years : I allude to "Lowe's Ferns.-" It consists of nine volumes, with 550 plates, containing figures of about two-thirds of the species in cultivation, with vague descriptions and many erroneous synonyms. This is a remarkable work in its way, but devoid of scien- tific merit ; the figures being the only part worthy of notice; many of them are good representations of species — all such I have quoted ; others are not to be relied upon, and tend rather to mislead. In the following pages I have classified Ferns and certain other Cryptogamic plants, called Fern allies,, under five orders, viz. : — Order I. Filices. Annulate, or true Ferns. „ II. Marattiaceoe. Exannulate. Ferns. „ III. Ophioglossacece. Adder's-tongue. Fern Ally. „ IV. Lycopodiacese. Lycopods. Fern A lly. „ V. Marsileaceoe. Khizocarps. Fern Ally The two first of these orders agree in having cir- cinate unfolding fronds, but differing essentially in habit and nature of their spore- cases; in the first, the spore-cases being membranous, and girded by an ar- ticulate ring, and the other firm and coriaceous, and destitute of a ring ; they also differ in the nature of their roots, true Ferns having slender filiform, often soft, mossy roots, or they are hard and wiry, whereas in Marattiaceoe. they are thick and fleshy, indicating quite a distinct habit of growth from that of true Ferns. The third order, Ophioglossacece, seems to possess some affinity to Marattiacece in the nature of its roots and spore- cases, but its straight vernation marks it as quite distinct. With Lycppodiacecc it is connected 70 FERNS : BEITISH AND FOKEIGN. through Pliylloglossum Drummondii, a singular little plant, having the appearance of a small plant of Ophio- glossum Lusitanicum, but with a spike formed of small bracts containing sporangia in their axis, analogous to Lycopodiacece ; otherwise the family of I/ycopods stands quite isolated, appearing to have no very evident transition forms connecting it with any other except the extinct order Lepidodendrece : the same may be said of the last order, Marsileacece. The most important of the above orders is Filiees. Sir W. J. Hooker, in the " Species Filicum," describes two thousand five hundred species of annulate Ferns, which, with those described since the first publica- tion of that work, twenty years ago, may now be considered to amount to no fewer than three thou- sand. To arrange and classify this mass of species is no easy task. The chief writers on Ferns adopt the difference in the position and direction of the ring, as the first important character for subdividing the order. This, however, divides it very unequally, the greater mass having the ring of the spore-case vertical, which characterizes the sub-order Polypodiacece ; this I have in the following arrangement subdivided into eleven tribes, as follows : — CONSPECTUS OF ARRANGEMENT OF ORDERS, SUB-ORDERS, AND TRIBES. .— Sporangia furnished with an articulate elastic ring.

OBS. — This genus probably consists of only a single species, and in affinity it may be ranked with Syngramma (not yet in cultivation), and is readily distinguished by its continual linear sorus, which is formed by the confluence of numerous short, oblique, sporangiferous receptacles. Specimens from the Fiji Islands exhibit fructiform or ovate scattered sori, which I consider to be only abnormal conditions, consequent on local influences affecting development. The name is derived from Tcenia, a tape or riband, in allusion, to the narrow pinnae. AN ENUMEKATION OP CULTIVATED FEUNS. 301 56. VITTABIA (p. 130). 2. V. remota, Fee; Hook. Sp. Fil t. p 185.— "W.
