PREFACE TO THE PRESENT EDITION. HAVE endeavoured in this Edition to briefly characterize and fit into their places the new discoveries and the plants found upon fuller information to have been inadequately dealt with in the first. A con- siderable number of new species have been described by Fée and others, which are, in my view, mere forms or synonyms of plants already inserted. It was never intended to make this Synopsis a resumé of synonyms, because fern-synonyms are now so many that a mere catalogue of names and references would fill a book far larger than this ; but by far the greater part of the new names not cited here will be found to be dealt with in a paper of mine on Binilinn Ferns in the Proceedings of the Linnean Society, which is not printed yet, but I presume will be early in vol, xiv. J. G BAKER, Kaw, April 28th, 1873. MR. BAKER’S PREFACE TO FIRST EDITION. — Wuitst the sheet which terminates at page 48 was passing through the press, Sir W. Hooker’s long career of botanical authorship was somewhat unexpectedly terminated by his death. This is not the place to enlarge upon the services which in many different ways he rendered to botanical science, or to do more than allude to the regret which will be felt by many who had waited for this long-planned work, that he was not spared to complete it. I need only say that having been honoured by Dr. Hooker with the request that I should carry it out, and having been entrusted by him with the manuscript notes prepared by his father, and the copy of the “Species Filicum” annotated in contemplation of this work, and having had full access to the specimens from which the descriptions in the “Species Filicum” were made, I have done my best to carry out this “Synopsis” to a conclusion in strict accordance with the original plan. The principal collection which we have received at. Kew since the original preface was written is a beautiful series of the ferns of New Granada, gathered by MM. Lindig and Triana, for which we have to thank the authorities of the Paris Museum. This contained a considerable number of new species, which were described by Professor Mettenius, whose loss in the prime of life we have also had to deplore since the work was commenced, For other novelties we have also to thank Lady Barkly, Dr. Thwaites, and Mrs. Lyell. Partly in consequence of these additions, we have been obliged to extend the work to ten parts instead of nine, as was planned originally. The total number of species admitted and described is 2,235. A paper by myself, containing a summary of the leading features of fern-geography, based upon this work, will appear in the part for 1868 (vol. xxvi. part i.) of the “Transactions of the Linnean Society.” J. G, BAKER. Kew, February, 1863, SIR W. HOOKER’S PREFACE TO FIRST EDITION. Tue Author, having recently compieted his “Species Filicum,”* now offers to the public a “ Synopsis of all known Ferns,” which contains, besides brief diagnoses of the species described more in detail in that work, together with their geographical distribution as far as yet ascertained, such additions and corrections as have come to his knowledge, together with an account of the Sub-Orders OsmunpAcrE#, Scuiz#aces, MaraTTiIaAces, and Opuxto- GLossAcEH. He does not, however, propose to include the Lycopodiacee, Salviniacee, Marsileacecee, Isoetacee, and Hquisetacee, which differ much from these, and it may be said from each other, and which have of late engaged the study of several able monographers. He further intends to depart from the scope of the “Species Filicum” in another point, which requires a few words of explanation. In the Introduction to the “Species Filicum,” the Author stated that he had included in that work a considerable number of imperfectly described species, of which he had seen neither specimens nor figures, solely because they had been proposed by authors of reputation. These he now thinks it desirable to omit. No doubt many are described under different names ; of others there is no prospect of anything further being known; and of all the characters are so vague, or imperfect, or prolix, that it is impossible to define them by brief diagnostic characters, such as alone are suited to the pages of a Synopsis. After upwards of half a century, more or less continuously passed in the study of Ferns in the richest Herbarium of that Order in the world (his own), and latterly with the aid of the finest in cultivation (that of the Royal Gardens of Kew) ; + and after the devotion of fully half that number * In 5 vols, 8vo, with 300 plates representing upwards of 500 species, + The formation of this fine collection is mainly due to the exertions and ability of Mr, John Smith, who for forty-three years held an important position among the officers of the Royal Gardens. His knowledge of Ferns, and his writings upon them, justly entitle him to rank among the most distinguished Pteridologists of the present day. b x SYNOPSIS FILICUM. of years to the preparation and publication of the “Species Filicum” and other works on the same subject, the Author feels satisfied that these doubtful and imperfectly described species form the greatest obstacle to any satisfactory advance in descriptive Pteridology.* He may, indeed, point with satisfaction to the fact, that before he undertook his work their number was many times greater than that still cumbering the volumes. But there is little satisfaction in the reflection that for the identification of a great majority the Author is indebted more to some happy accident, to the possession of copious and varying suites of specimens, or to circumstances connected with the history or locality of the species, than to their published descriptions or to scientific evidence. There have been two fruitful sources of these “bad species” :—the first, the idea that geographical limits must limit the dispersion of species ; the second, that any single characteristic, however minute, if only either con- stant or prevalent in a given area, is of specific value. Such arbitrary conclusions have led to the well-known Osmunda regalis receiving different names in many different countries, and to the forms of our Aspidium (Polystichum) aculeatum having even more names in our own country, and still others in exotic regions. The errors arising from the first are corrected as rapidly as botanical and geographical discoveries advance together ; but it is not so with those due to the second source, for the difficulty of limiting these variable species is so great, that it often becomes impossible to frame such diagnoses as shall include all the varieties of one species, and exclude the varieties of another closely allied species. In all these cases we must trust to time and experience to test our conclusions ; and such difficulties should teach us to look with indulgence on the views of those who differ in opinion from ourselves. The same remarks apply to the genera as to the species of Ferns; the former having been, in the Author’s opinion, unnecessarily multiplied. It * Tn connection with Fern history, Mr. Thomas Moore undertook the publication of an extremely useful work under the title of “Index Filicum,” to consist of a Synopsis, with characters of the genera, and an enumeration of the species of Ferns, with synonyms, references, &c., &c., accompanied by excellent outline figures of the genera. It is compiled with great industry and ability, and enumerates in an alphabetical arrangement of the genera, from Acrophorus to Goniophlebium inclusive, 1,730 species of true Ferns, The list of synonyms, both of genera and species, shows at a glance how much Pteridologists have been at variance on these points. The species enumerated in our “Species Filicum” amount to 2,401 ; according to Mr. Moore, the number of known Ferns would be 2,482. PREFACE. xi is the case here as with other scientific systems; those are the best cha- racters which lead to a knowledge of the object sought for in the nearest and clearest way, keeping in view also as much as possible its natural affinities. The difficulties certainly are greater in the cryptogams than among the flowering plants, because their characters are fewer, and the forms of their organs more variable as regards size and shape. In regard to the genera, the publisher has judiciously desired that nine plates should be devoted to their illustration. They are all drawn from nature by the talented Mr. Fitch, F.L.8., and on the same plan as the plates of Ferns in Hooker and Arnott’s late editions of the “ British Flora.” References are given to the volumes and pages of the “Species Filicum” for fuller characters of the genera and species, as well as for figures, more precise localities, and more copious observations ; and it is hoped that the present volume will form a useful vade-mecum for the travelling botanist and the cultivator of Ferns, and for ready consultation in the Herbarium. : The Author cannot close these introductory remarks without expressing his acknowledgments to numerous friends and correspondents for their valuable communications of specimens (often accompanied by notes) from various parts of the world. Many of these are recorded under their habitats (or localities) in his former work ; and a repetition of them would be out of place in this. But space must still be found for the names of those persons to whom we are indebted for the discovery of any new species, or any new or interesting locality in connection with the geographical distribution of plants. The commencement of the Author’s formation of a Fern-Herbarium dates as far back as 1811, with the correspondence of the illustrious Swartz, only four years after the publication of his invaluable “ Synopsis Filicum ;” a model for future works of the kind. It is, however, from comparatively new and distant regions, which have been within the last half-century so extensively explored by our men of science, that the most important collec- tions have been derived, and to these botanists and travellers he is anxious thus to express his obligations :— From the Last Indies, including the Malay Peninsula and Islands :— From Wallich, Buchanan, Hamilton, Hooker fil. and Thomson, Gideon Thomson, Beddome, Lady Dalhousie, Anderson, Falconer, Jamieson, Edge- worth, Sir Frederick Adam Jacquemont, Blume, Miquel, De Vriese, Teijsmann, Sir William Norris, Thomas Lobb, Cuming, Wallace, Low, xii SYNOPSIS FILICUM, Hindes, Barber, Parish, Teschemacher, Motley, Millett, Wight, Stocks, Helfer, McIvor.

Tropical and subtropical regions, almost universal, in the New and in the Old Worlds ; Pacific Islands, and as far north as Japan.—As G. pectinata is a solitary species of its section, so is G. dichotoma of the present one. Besides being most extensively geographically distributed, it is very variable in the size of the pinnz and in the shape of the segments, and in being more or less glabrous or densely tomentose beneath, green or glaucous, and very variable in the ‘texture of the frond: but the pairs of accessory pinne at the base of a fork are invariably present. There are also abnormal or aberrant forms. Among them I have specimens with lobes of the pinnz free (pin- nules) and more or less deeply pinuatifid, from Penang and Java. I have others from Java, which Mettenius (Ann. Mus. Bot. L.

But his views, and their practical carrying out with regard to the limitation of genera and species, were the very opposite of those of Sir William Hooker, as may be judged from the fact that in his Synopsis and Supplement, 450 so-called species are given, and that out of what are here considered two genera, he makes twenty-four. Upon this point Sir William Hooker wrote : ‘‘ This genus and the following one have had their Species multiplied to an extent with which I cannot at all concur. The late learned Dr. Van den Bosch, in his widely-scattered publi- cations, has no doubt described many new species, which-it has not been in my power to identify ; but having been favoured with his opinion on a large portion of my collection, I regret to be compelled to join with my friend Dr. Grisebach in the opinion expressed in his ‘Flora of the British West-Indian Islands,’ that many of the species are not well tounded.” 16.

China, Malayan Peninsula, and Tropical America from the West Indies southward to Brazil.—This differs only from P. guadriourita in the pinne being less deeply pinnatifid, and the bases of the midribs of the segments being _ connected by an arching vein. This arch springs normally from the bases of the midribs, but sometimes begins and ends at points between them. It is sometimes triangular, but sometimes very low, and in what Agardh considers as P. nemoralis, Willd., we have the venation considered as characteristic of biaurita combined with the entirely free vena- tion considered as characteristic of qguadriaurita in one and the same frond, so that they must be regarded as very doubtfully distinct. P. Galeotti, Fée; P. amena, Blume; P. Mettenti, Kuhn ; and P. armata, Presl, are apparently allied plants ; and C.

America—Sitka and Labrador to Cuba, Caraccas, and Venezuela. Of the common European forms 4. Filix-farmina is a large plant with narrow lanceolate deeply pinnatifid pinnules ; 4. rheticum, Roth, is smaller, with the pinnules broader, and not so deeply cut; A. molle, Roth, thinner in texture, with oblong rhomboidal pinnules } in. broad ; and A. latifolium, Bab.

Indian A. pectinatum, Wall., is very thin in texture, and has deeply-cut pinnules, with narrow spreading segments. A. tenutfrons, Wall., is like A. molle, but with the midrib of the pinne and pinnules beset with firm yellow spines or strigillz ; as is also the case with various Indian, Ceylonese, and Javan forms, with narrower, more slender, and more straggling pinne and pinnules,—as A. gracile, Don; A. stramineum, J.

The two genera thus obtained have a closely similar range of variation in cutting and venation, and it is by no means clear in which of the two several species should be placed. It is perhaps scarcely needful to warn the young student to bear constantly in mind that an Aspidium with an abortive or obliterated involucre is not distinguishable from a Desmobryoid Polypodium. The number of species which have been originally described as non-indusiate, in which a more or less (often very slightly) developed involucre has been afterwards found to exist, is very considerable, and no doubt more will be added to the list. : 260 44, NEPHRODIUM, § LASTREA. naked ; veins in pinnated groups, casually anastomosing ; soré large, in rows near the main veins.—Hk&.
