THE second edition of Hooker and Baker's Synopsis
Filicum (now out of print) brings the enumeration of
genera and species up to the year 1874. Since that date
a large number of novelties have been discovered and described
and so much fresh light has been thrown by morphological
investigation on the taxonomic relations of the different groups
of plants included under FlLlCES that it is time for a new
handbook. As there is not any chance of this being produced
at present, I propose in this paper to attempt a general sum-
mary of what has been added to our knowledge in respect to
species during the last sixteen years. I do not intend to describe
again the plants that have been described already ; but merely
to indicate their position in the sequence followed in the
Synopsis, in the same way as in the supplement published in
the second edition. Most of the larger collections that have
been received at Kew have been already published in Britten's
Journal of Botany and in the Transactions and Journal of the
Linnean Society, but a considerable number of new species
which have been received from time to time are still unnoticed.
Of many of the plants which have been described by other
authors we possess authentic specimens. Some of these I can
only place as synonyms, and others, measured by the standard

2 Baker. — A Summary of the new Ferns

of specific difference adopted in Synopsis Filicum, as forms or
varieties. Of the distinctness of published novelties of which I
have not been able to see specimens, it is almost impossible
to judge, but I have indicated the position they would occupy
in the Synopsis as well as I could from the published descrip-
tions. In a few cases fresh material that has been received
shows that species that are passed over in the book for want of
knowledge ought to be maintained, or that species kept up as
distinct in the book ought to be combined.

Besides innumerable papers in journals, in the proceedings
and transactions of societies and in local floras that include
ferns (which I need not attempt to enumerate, as they will appear
in the citations), the two principal books that concern our
subject that have appeared since 1874 are Beddome's most
useful Handbook of the Ferns of British India, published at
Calcutta in 1881, and Father Sodiro's ' Recensio Cryptogama-
rum Vascularium Provinciae Quitensis ' published at Quito in
1883. The sixteenth century of Hooker's Icones is devoted
entirely to Ferns. The principal collections which contain
new species have been made in Madagascar by Pool, Miss
Gilpin, Kitching, Baron, Humblot, Hildebrandt and Last ; in
China by Henry, Faber, Ford, Hancock, Maries and Delavay ;
in Perak by Scortechini ; in Tonquin by Balansa ; in the Malay
archipelago by Beccari, Burbidge and Dr. Hose (Bishop of
Singapore and Sarawak) ; in New Guinea by Beccari and Sir
William Macgregor; in New Caledonia by Vieillard and
Balansa ; in Polynesia by Moseley (Challenger expedition),
Home, Sir J. B. Thurston and the Rev. R. B. Comins ; in the
Western United States by various collectors ; in Mexico by
Pringle, Parry and Palmer ; in Costa Rica by Harrison and
Cooper; in the West Indies byjenman, Hart, Nock, Sherring
and Fendler ; on the Roraima expedition by im Thurn ;
in New Granada by Kalbreyer ; in Ecuador by Father Sodiro ;
and in Brazil by Glaziou. In this enumeration the species
are numbered as in the Synopsis Filicum. Novelties are
indicated by an asterisk attached to the numbers of the
species to which they are most nearly allied.

GLEICHENIACEAE.

Genus 2. GLEICHENIA Sm.

3. G. circinata, S\v. I cannot separate specifically G. patens,

Colenso in Trans. New Zeal. Instit. 1888, 212.

4. G. rupestris, R. Br., must evidently be placed as a mere variety

of G. circinata.
8. G. littoralis, Colenso, in Trans. N. Zeal. Inst. 1883, 334, I

cannot separate from G. flabellata.
12*. Mertensia littoralis, Philippi, Descr. Nuev. Plant. 1873, 104.

Chili. Not seen.
15. G. subandina, Sodiro, Recens. 5, and G. hypoleuca, Sodiro,

Recens. 8, Andes of Ecuador, I should place as varieties of

G. revoluta.
17. G. seminuda, Moore, Ind. Fil. 383, Columbia, G. blepharilepis,

Sodiro, Recens. 6, and G. leucocarpa, Sodiro, Recens. 8, Andes

of Ecuador, I should place as varieties of G. pubescens.
17*. G. intermedia, Baker, in Journ. Bot. 1887, 24. Costa Rica,

Cooper, Intermediate between pubescens and dichotoma. There

are two varieties, flexuosa and dissitifolia.
19. G. Brackenridgei, Fourn. in Ann. Sc. Nat. sdr. 5, XVIII, 269,

New Caledonia and Fiji, and G. oceanica, Kuhn, Hook, and

Baker, Syn. Fil. edit. 2, 449, should probably be classed as

varieties of G.flagellaris.

23. G. linearis, Clarke, in Trans. Linn. Soc. ser. 2, I 428, (Poly-
podium lineare, Burm.), is a synonym of G. dichotoma, Hook.

CYATHEACEAE.

Genus 4. CYATHEA Sm.

Bommer proposes to divide Cyathea into three genera, viz. i,
Cyathea, indusium of one single indehiscent piece; 2, Eatoniopteris,
indusium of one piece, membranous, breaking up into fragments;
3, Fourm'era, indusium formed of a number of narrow hyaline im-
bricated scales. For my own part, I feel more inclined to unite
Hemitelia to Cyathea than to divide Cyathea as it now stands.

bipinnatifid, subrigid, glabrous. Pinnae oblong-lanceolate, i-i£
ft. long. Pinnules lanceolate caudate, 2^-3 in. long, £- f in.
broad, cut down by a broad wing into oblong tertiary segments

fronds, the plants which have been widely spread in gardens
under the names of Ahophila Malzinei and A. Vangeertii are
forms of this species.

In the second edition of the ' Synopsis Filicum,' in 1874, about 200

tree-ferns are described as distinct species. Since that date upwards

of eighty new ones have been found.

Genus 8. MATONIA R.Br.

M. sarmentosa, Baker, in Journ. Linn. Soc. XXIV, 256 (see Plate
XIV). Rachis slender, terete, with long internodes. Segments
3-4 from each internode, linear, rigid, glabrous, simple or forked,
4-5 in. long, £ in. broad. Veins indistinct, simple, or forked.
Indusium globose, rigid, superior, attached by a short central
stipe, splitting by circumscissile dehiscence, so as to leave a
patelliform persistent base. Sporangia 8-10 in a cluster, with
a short stipe and incomplete vertical ring. Niah, Sarawak,
Borneo, collected by Mr. Charles Hose in 1887, sent to Kew
by the Bishop of Singapore and Sarawak.

This is the most interesting novelty that has been found
during the period which this paper covers. It has entirely the
indusium and sporangia of the old well-known Matonia pecli-
nata, on which this genus was established by Robert Brown,

12 Baker. — A Summary of the new Ferns

but the habit of the plant is entirely different. Matonia ought
clearly to form a tribe by itself, not to be united with the
Cyatheaceae.

POLYPODIACEAE.

I should like to separate Hymenophyllaceae from Polypodiaceae as
a distinct sub-order, and divide the latter into four tribes as follows :
viz. (i) Indusium none (e. g. Acrostichum, Polypodiujn) ; (2) Indusium
formed only from the altered margin of the frond (e. g. Adi'an/um,
Pteris) ; (3) Indusium formed in part from the altered margin of the
frond, with an inner valve in addition (e. g. Dtcksonia, Lindsaya) ;
and (4) Indusium truly dorsal (e. g. Aspidium, Asplenium).

Genus 14. DEPARIA Hook, et Grev.

1. D. prolifera, Hook. A plant lent to us by Sir F. Mueller, from

Genus 14*. LECANOPTERIS Blume.

I now think this will have to stand as a distinct genus in the
neighbourhood of Dtcksom'a, from which it differs by having the in-
dusium formed from a single valve, and curious tuberous rootstock,
with species as follows, viz. : —

1. L. carnosa, Blume, Fil. Jav. tab. 94 A. Perak and Philippine and

Malay Isles.

Genus 21. ADIANTUM Linn.

Kuhn, in Jahrb. Berlin. Bot. Gart. vol. I. p. 337, has published a
valuable monograph of this genus. He characterises briefly 113

rangia confined to the veins ; and (2) Adiantellum, sporangia
occupying the intervening parenchyma as well as the veins.

discovered or described since 1874. 53

Genus 41*. TRIPHLEBIA, Baker.

Differs from Scolopendrium and agrees with Diplora in having
a prominent receptacle running down the centre of the sorus.
Here it arises from a sort of adventitious vein, not always
produced beyond the sorus, but in Diplora the receptacle runs
along the proper vein, and the two valves of the indusium do
not spring from veins.

Four species are known, as follows : —

1. T. pinnata. Baker, in Malesia, III, 41 : Hook. Ic. t. 1652 =

Scolopendrium pinna/urn, J. Sm. Philippines, Cuming, 137, 311.

Maximowicz, Moseley, and Dickins.

316. P. glabrum, Mett. Authentic specimens from R. Brown's

323, on which Gymnosorium samarense, Presl, Epim. 140, is
founded, is Niphobolus van'us, to which it was long ago referred
by John Smith ; but I do not think the plant, of which a scrap

21. A. Phyllitidis, Sw. Mr. Carruthers tells me that the type

specimen of A. hirsuta, Sw. in the herbarium of the British
Museum ranges here.

22. A. aurita, Sw. Has now been found in Porto Rico.

Genus 66. MOHRIA, Sw.

1. M. thurifraga, Desv. Has now been found in Angola, the

Zambesi highlands, and on Mount Kilimanjaro.

2. M. vestita, Baker, in Hook. Ic. t. 1696. Mount Kilimanjaro,

in crevices of rocks at 6000 feet, H. H. Johnston.

3. M. lepigera, Baker; Notochlaena lepigera, Baker, in Journ.

Bot. 1884, 53. Mount Dzomba, Zambesia, alt. 6000-7000
ft., Sir John Kirk.

Genus 68. LYGODIUM, Sw.
5*. L. hians, Fourn. in Ann. Sc. Nat. ser. 5, XVIII, 355. New

Caledonia, Balansa, 1564, 2737, Vieillard, 2606. Near Z.

articulatum, A. Rich, of New Zealand.
7*. L. gracile, Baker, in Journ. Bot. 1888, 35. San Domingo,

Baron Eggers, 2536.

11. L. polystachyum, Wall. Has lately been found in Anam by

Dr. Kuntze.

12. L. subalatum, Bojer=L. Kerstenii, Kuhn. The latter name

having a short priority in publication.

Prantl transfers the name of Z. pinnatifidum, Sw. to Z. poly-
stachyum, Wall., on the ground that it was Willdenow's Hy-
droglossum pinnatifidum, in part. : he divides L. pinnatifidum of
our Synopsis into two species, calling the Asiatic plant
Z. salicifolium, Presl, and the African Z. smithianum, Presl.

MABATTIACEAE.
Genus 71. DANAEA, Sm.

5*. D. serrulata, Baker, in Journ. Bot. 1881, 208. Hook. Ic. t.
1699. Antioquia, New Granada, Kalbreyer, 1352.

8. D. moritziana, Presl. Has lately been found in Jamaica and

Costa Rica.

11*. D. polymorpha, Leprieur. Stipe long, i -jointed. Sterile
frond oblong, a foot long; rachis not winged; pinnae 7-9,
petioled, oblong-cuspidate, the end one the largest, 5-7 in.
long, 2-2 \ in. broad; veins distinct, erecto-patent. Fertile
frond with a jointed stipe \\ ft. long and 9-11 narrower
pinnae. Guadeloupe, MazS; Grenada, Shern'ng. Perhaps a
mere variety of D. elliptica. D. oligosora, Fourn., also
gathered by Fournier in Guadeloupe, has about the same
number of pinnae as D. polymorpha, but they are only \\-\\
in. broad, and narrowed more suddenly at the base.

OPHIOGLOSSACEAE.

Genus 73. OPHIOGLOSSUM, Linn.

The genus is monographed very carefully by Prantl, in Jahrb.
Bot. Gart. Berlin, III, 297, tabs. 7-8. He admits 29 species,
dividing into several our 0. lusitamcum, nudicaule, and vul-
galum, on characters furnished by the rootstock and the
venation of the barren frond.

1*. O. minimum, Armstr. in Trans. New Zeal. Instit. 1880, 342.
New Zealand. I have not seen a type-specimen, but suppose
it to be identical with O. coriaceum, A. Cunn., which is kept
up as a species by Prantl.

5*. O. costatum, R. Br. Prodr. 163, should clearly be kept up as
a primary species. It is spread from North Australia to
West Africa and under it range O. brevipes, Beddome, O.
Wightii, Hook, et Grev., O. aphrodisiacum, Welw., and
O. flbrosum, Schum. et Thonn.

7. O. intermedium, Hook. Further material shows this a mere
form of O. pendulum.

9. O. palmatum, L. Has now been found in Florida and

Madagascar.

Genus 74. HELMINTHOSTACHYS, Kaulf.

1. H. zeylanica, Hook. Has now been found in the Solomon
Islands and New Guinea.

discovered or described since 1874. 117

Genus 75. BOTRYCHIUM, Sw.

Monographed by Prantl along with Ophioglossum, as above cited.
He admits 15 species out of substantially the same materials
as our six.

3. B. Lunaria, Sw. Has now been found in New Zealand and

the Northern United States.

4. B. ternatum, Sw. The New Zealand B. biforme, Colenso, in

Trans. New Zeal. Instit. 1885, 223, exactly matches the
North American B. dissecium, Muhl.
