A SECOND CENTURY OF FERNS; BEING FIGURES WITH BRIEF DESCRIPTIONS or One Hundred NEW, OR RARE, OR IMPERFECTLY KNOWN SPECIES OF FERNS: FROM VARIOUS PARTS OF THE WORLD; BY SIR WILLIAM JACKSON HOOKER, K.H., LLD., F.R.A., AND LS. &e. &e, DIRECTOR OF THE ROYAL BOTANICAL GARDENS, KEW. LONDON. WILLIAM PAMPLIN 45, FRITH STREET, SOHO SQUARE. MDCCCLXI. ® ZCORN FILS % UNIVERSITY, \ LIBRARY 7 TO DR. GEORGE METTENIUS, PROFESSOR OF BOTANY, AND DIRECTOR OF THE BOTANIC GARDEN AT THE UNIVERSITY OF LEIPZIG, THE ABLE AUTHOR OF «“FILICES HORTI BOTANICI LIPSIENSIS,” AND OF VARIOUS MEMOIRS, “UBER EINIGE FARRNGATTUNGEN,” THIS CENTURY OF FERNS IS DEDICATED, IN TESTIMONY OF GREAT RESPECT AND ESTEEM, BY THE AUTHOR. Royat Garpens, Kew, May, 1861. PRHEFATORY NOTICKH. Or all the Families of plants, perhaps there is none that needs so much to be illustrated by figures as the FERNS. They are, from their variableness of character, and owing to the different forms they exhibit in different individuals of the same species, and even in different parts of the same individual, especially in the very compound kinds, exceed- ingly difficult of verbal definition, and hence the descriptions of writers have been so greatly misunderstood, even those that have been the most full and most accurately worded. It was the want of such Fern-figures, as helps to a more thorough knowledge of these lovely plants, that induced us to devote the whole of the last volume (the Tenth) of our *Tcones Plantarum,” exclusively, to this Family, and we think Mr. Pamplin did right in issuing copies of this volume separate, to those who might not care to possess the entire work, and under the title of a “CENTURY oF Frrns.” So favourably was this volume received that it has induced the Author to publish another and “Srconp Crnrury,” the volume now before us. There is indeed no scarcity of materials for many such volumes, could sufficient patronage be insured ; for the dis- covery of new species has of late years been quite extra- ordinary, im different parts of the world; and it would be still more extraordinary if we could persuade ourselves vill. that all that go by the name of new discoveries, were really so. If we take Mr. Moore’s useful and laborious “ Index Filicum ” as a test of the numerical statistics of Ferns, the number appears great indeed. The eleventh part of this “Index” has recently been issued, bringing the Catalogue down to the letter C, and to the end of the genus Cuspidaria. Thus the work at present only embraces the Genera (alpha- betically arranged) of the first three letters of the alphabet (A—C). These include 47 Genera and 1069 species!’ The total of such genera to be recorded are 186, of which about one-eighth only have been elaborated, so that if we consider the remaining seven-eighths of the genera to possess the same proportional amount of species, which may possibly be the case, this brings us to 8000 different kinds of Ferns described in books by persons worthy of credit from their name and character; to say nothing of the multitudes of synonyms, which are legion. But it must be recollected that Mr. Moore necessarily reckons, as species of authors, a great number which he has no means of verifying, nor of judging whether they ought, or ought not to be rejected, as he has done in the case of many others :—and of which there is too much reason to fear that a large proportion would come into the latter category. If we reckon the number of well-ascertained Ferns at half the amount enumerated in the “Index Filicum,” viz. at 4000 species, it will perhaps nearly accord with the truth. Nothing will so much tend to a correct knowledge of these as accurate figures, published on a cheap scale, as dre the two “ Centuries” now under consideration:—and we have had ix, the privilege of bringing into notice many novelties of great interest derived from the researches of our friends and corres- pondents in different quarters of the globe, from some coun- tries of which, till now, the vegetable productions were comparatively unknown to the man of science. We allude particularly to the Fiji Islands, to Japan and China, to Borneo, Tropical Africa, East and West, &c. &c.; the results of the labours of Brackenridge, Milne, Macgillivray, Harvey, Seemann (Fiji); Wright, Wilford, Urquhart, Alcock, Hodg- son (China and Japan); Low, Motley, Lobb (Borneo) ; Vogel, Baikie and Barter, Kirk, in Livingstone’s Expedition (Tropical Africa), and others too numerous to mention, but whose names stand recorded in these pages. Not a few we trust will be found faithfully and unmistakeably exhibited in our two Centuries; and many, for which we have no space here, will be received, and if possible figured in our “ Species Filicum,*” now in course of Publication.

Trichomanes Henzaianum, Parish in litt. Has. Detected by Mr. Henzai, and the Rev. C. S. P. Parish, partially clothing the trunks of trees at Moulmein, 1859. Dr. Van Den Bosch, of Leyden, distinguished by his wri- tings and admirable figures of Mosses, is now happily engaged on a monograph, with numerous figures on the beautiful family, among Ferns, of Hymenophyllacee. He has already given to the world a valuable “Synopsis” of the group, with full de- scriptions of new or critical species. Our present individual, will rank near to Tr. sublimbatum of Mueller, to which Van Den Bosch refers, and probably quite correctly, my Java form of Tr. muscoides, (Sp. Fil. i. p. 117). From that, however, our plant may be known by its much smaller size, and different form, greener color, more delicate texture; but, above all, by the involucre, of which the limb in 7. sublimbatum extends to the margin of the frond, while in our plant, the lobe of the frond extends much beyond the involucre; and has, indeed, the appearance of half an involucre attached to the frond, as occurs in not a few davalliaceous plants.

A very remarkable and very pretty Fern, for which I am indebted to Mr. Wright and Mr. Eaton, who observe (in litt.) that this ought, perhaps, to be made the type of anew genus; for that “the parts of the indusium imbricate over each other.” It is however, I think, very difficult, where the indusium (or involucre) is of so very delicate and fragile a nature, to say whether it is of the structure now mentioned, or whether, being first entire, it may not afterwards burst from the top into a few unequal valves, which may appear to be imbricated, and as is the case in the group or subgenus Physematium, Klfs. (Hymenocystis, C. A. Meyer), to which Mr. Eaton has, as it appears to me, properly referred it. Fig. 1. Fertile pinna, seen from beneath. f£ 2. Portion of the same. (f. 3.

A very peculiar looking Asplenium, entirely of a black colour in its dried state, having the short stipes and rachis clothed with patent, long-spreading, intensely black, palea- ceous flexuose hairs, or scales. The appearance of the entire plant is that of having grown in water, and the pinne and segments are more or less erose, and jagged at the margin, and the substance is formed of closely compacted cells, in the younger and subpellucid specimens exhibiting a minutely reticulated appearance, when held between the eye and the light.

Lady Lyell. Wako- dadi, Japan, C. Wright. A single glance at the fertile pinnz of this fine species, is sufficient to assure any one of its distinctness from S. Germanica, of Willdenow (Pensylvanica of the U. States Botanists); not only are they much longer and broader and flatter, (less cylindrical) and never moniliform; but the invo- lucre is of a very different nature, so broad as completely to cover the back of the pinnules, the entire edges meeting at the back, and never breaking up into uniform segments; and the texture is thin and membranaceous, but firm, very glossy, and of a very dark chestnut colour, suddenly con- duplicate, and pressed close to the sori on the back; whereas in S. Germanica, the moniliform fertile pinne have the invo- luere rolled back as it were, so as to cover the sori, and of the same texture and color as the pinna itself. The sterile frond too, which is much attenuated at the base, is here abrupt. As a species, it may probably be found to have as extensive a range in the Eastern, as S. Germanica has in the Western world, (including Europe in this region), for it has already been found in Sikkim Himalaya. I detected one specimen in a collection of Assam Ferns; and it appears again in the Northern Island of Japan, Hakodadi. fig. 1. Small fertile pinna. f. 2. Portion of a fertile pinna; magnified. f. 3.

Caudice crassiusculo repente, frondibus vix stipitatis digitali- bus firmis rigidis dense cespitosis lineari-lanceolatis pin- natis, pinnis remotis patentibus apice piliferis, steribus angustissime linearibus, fertilibus spathulatis acutis margine superiore reflexo, vena (seu costa) solitaria infra apicem terminante clavata sorifera, soris solitariis oblongis apicem dilatatum pinne occupantibus, rachi angusta lineari-suba- lata patentim villosa, Has. Kina Ballu, Borneo, Hugh Low, junr. Esq. As far as I can judge from Fée’s figure and description of his Plectopteris gracilis, it is identical with the Calymmodon cucullata of Presl, and the Grammitis cucullata of Blume, and of J. Smith; and no less so with Grammitis denticulata of Blume, (Polypodium cucullatum of Nees and Blume in Nov. Act. Acad. Nat. Cur., and P. denticulatum of Bl. Syn. Fil. Jav.) If this be correct, this genus (or section of Polypodium or Grammitis, according to the views of Botanists,) is reduced to a solitary species; but to this I have added the very elegant Fern now before us, which I prefer retaining in Grammitis. Jt is readily distinguished by the more slender habit, and deeply and narrowly divided frond, rather pinnate (with the rachis narrow-winged) than pinnatifid; the sterile pinne are narrow linear almost acicular, while the fertile ones are truly spathulate or claviform, and mostly confined to the middle or upper part of the frond. I may observe that the Grammitis cucullata, of an un- usually large size, is also found on Kina Ballu, by Mr. Hugh Low, junr. Fig. 1. Portion of a fertile frond, seen from beneath. f 2.

Haz. Andes of Quito, on the banks of the river Hondacha, Jameson, n. 780. On Mount Picdte, near Moyobambu; Peru, C. W. Nilson (in Spruce’s Plants of Peru, n, 4780 ). A very pretty and very peculiar species of the extensive Genus Polypodium, of which I do not find any description, and which seems confined to the Andes of Ecuador and Peru; at least, I have seen it from no other quarter. It is remarkable in the almost ligulate form of the small thin and membranaceous fronds, cut at the margin, with great regu- larity, into very short and obtuse lobes; the whole, on both surfaces, and at the margin, clothed with long, but rather sparse fulvous hairs. The color is pale green; in the older specimens stained with yellow and brown. The fronds seem destitute of stipes, and are decurrent to their very base, where the costa is often blackish. It may rank near the West Indian P. Serricula of Fée, but that has much narrower fronds, deeply pinnatifid, the lobes 1-veined, and the sorus placed within the lobe. Fig. 1.

Kunze, and following him, all succeeding authors have pronounced that the admirable figure of Gymnogramme “ cordata,” of Dr. Greville in Ic.

We maintain, that it perfectly accords with all the essential characters and full descriptions of the illustrious Swede: but it ill accords with what Kunze figures and describes as the G. Capensis ; nevertheless, we are quite willing to declare our opinion that the two are varieties of each other, for we can trace them through their several stages in our Herbarium, in the following forms or varieties. 1.

Brazil; dense woods on Mount Cupati, near the River », Japura, Martius, Near Tarapota, Eastern Peru, on Mount Guayrapurima, Spruce, 1856. One of the rarest and most beautiful of Ferns, with its undivided reniform fronds, and the curious crescent-shaped mass of sori, and the glossy ebeneous stipites. I am not aware that it has ever been gathered, but by the two eminent Botanists and 8. American travellers just mentioned. Mr. Moore, in adopting the Genus Perozonium, does not fail to remark, that it is “technically not very different from Gymnogramme, but the aspect of the plant is so peculiar, that the parallel contiguous receptacles, from which result a broad submarginal confluent sorus, may well be considered sufficiently distinctive.” I am not aware that its habit is more peculiar in the genus than the Gymnogramme figured in our preceding plate, which, nevertheless, Mr. Moore properly retains in that genus, rather than adopt J. Smith and Fée’s Hecistopteris. At any rate, our present Fern is not more remarkable among the species of Gymnogramme, than Adiantum reniforme and asarifolium and Parishti, Trichomanes reniforme, and Lindsea reniformis, are in their respective genera. ee appears to have gathered specimens nearly a foot tall.

A. trapezoides, indeed, is a more appropriate name than A. trilobum ; but the latter has the right of priority. Our Aspi. parvulum of the Icones Plantarum, is merely a smaller and young state of this; we were the more disposed to think it distinct, from its being detected on the Atlantic side of America: having been previously known only on the Pacific coasts.

This is one among the many Andinian Ferns, which, as far as my researches extend, I take to be new, and for which I am indebted to Prof. W. Jameson’s zeal and kindness. It is a graceful Fern, probably pendent in its native locality, judging from the slenderness of the stipes and a peculiar curvature in many of the specimens at the setting on of the frond upon the stipes. ig. 1.

Andes of Quito, Prof. W. Jameson. That the species of the Genus Xtphopteris are very vari- able, is notorious to every student of Ferns; and, I be- lieve that the X. myosuroides and .X. serrulata are now gene- rally looked upon as forms of one species. It may, there- fore, be considered a bold step to constitute a species of the present singular and particularly neatly formed kind, which, at first sight, and independent of its fertile caada, has more the appearance of some neckeroid moss, or some delicately pinnated Jungermannia, than a Fern. Instead of being only strongly “toothed” as is characteristic of Xiphopteris gene- rally, it is so deeply pinnatified, nearly to the rachis, that it might almost be called pinnate: and im an advanced state of the plant, these segments or pinne, fall off partially or en- tirely, leaving the rachis like a long, stout, naked bristle. Mr. Moore, whose views always deserve attention, observes, that to him the sori of the genus appear to be produced in a line contiguous to the mid-rib, and seem little different from Pleurogramme. To me, they appear to be decidedly on the lateral thickened veins, extending from the costa to the apex, just within the margin: so difficult is it for all to see with the same eyes, and so much is there yet to learn, in the structure of the fructification of Ferns, Fig. 1.

This is, doubtless, a very sportive plant, but its main feature is occasioned by its extraordinary tendency to send out new plants from axillary and terminal gemmz, which take root, cover a great extent of ground, and hinder the real form and structure of the frond from being distinctly seen. One can hardly conceive, why so many names should have been adjudged to this plant, and even the honor of a new genus. Fig. 1. Base of a pinna, seen from above. Jf. 2.

This fine Fern has been largely distributed by the late Dr. Wallich, under the name of Asplenium (Diplazium) Sfraxinifolium ; and I am desirous of making it known to the botanical world ; for as far as I am aware, it has been noticed by no Fern-author in any way, save that, in Moore’s Index Filicum, Wallich’s Asplenium fraxinifolium is called “ Di- plazium fraxinifolium.” My impression is that this Fern, with its free venation will prove specifically identical with Diplazium (Oxygenium) elegans, figured in Hook. Ic. Pl. t. 939-940, notwithstanding the anastomosing venation of the latter. I would observe, too, that the Diplazium alternifolium, Bl. (and Hook. Fil. Exot. Tab. 17) has, though possessing much broader pinne, great affinity with this; but the whole group of diplazioid Asplenia require a careful study and revision, which we trust to attempt ere long.

Acad. 1. p. 268; though it is quite clear that Linneus had quite another Fern in view, since he says of it, in Sp. Plant p. 1523, “ fructificationes sunt puncta confertissima, versus apicem frondis,” and he refers to Hort. Malab. 12. t. 27. But Swartz, long ago, showed that the Linnean plant was the Polypodium acrostichoides of Forst. Prodr. now generally referred to Miphobolus. Feée afterwards in his Genera Filicum refers Linneus’ Acros- tichum lanceolatum to Dendroglossa ; while Moore places it in his Gymnopteris, among the Pleurogrammee. Fig. 1.

Late events have contributed to the opening up to us of the Botany of N. China and Japan, whose geographical position naturally led us to expect European forms of Ferns. The present species was at first considered by me to be a state of Aspl. lanccolatum, while Mr. Eaton looked upon it as more related to Asp/. fontanum. More copious specimens have satisfied me it is truly distinct from both. The young fronds are simply and closely pinnated, with obliquely ovate pinne. Fertile Fronds :—nat size. Fig. 1.

Siberia, River Angara, Steller; Kamtschatka, Georgi, Island of Tsus Sima, Strait of Korea, Wilford, n. 790. Linneus gives “ Siberia” as a locality for the N. American Asplenium (Camptosorus) rhizophyllum. The Siberian plant is however since acknowledged to be a new species, distinguished by the entire absence of lobes or auricles at the base of the frond, which are so characteristic of the United States. But even in Siberia the present species appears to be of very rare occurrence, insomuch that the late learned author of the Flora Rossica (Ledebour) was obliged to declare “species mihi ignota.” Only two stations for it have been yet re- corded in all the Russian dominions; and now that it has been detected in the island of Tsus Sima, off the coast of Korea, the discoverer there accompanies his specimen by the remark “ the only specimen found ;” and that is the one here represented. Camptosorus and Antigramme only differ from Scolopen- pendrium by the partial anastomosing of the veins; in the former next the costa; in the latter next the margin. To me it seems most natural to unite both with Scolopendrium. Fertile and barren fronds. F%g. 1.
