Unknown species of Goniopteris. 
1. Goniopleris macrocladia Fée, Cr. vasc. Brés. 1: 106 tab. 33 right-hand figure 
(“fig. 1”). 1869 — Brazil: Sta Catharina, ALBURQUERQUE. It seems to be 
distinct from all Brazilian species known to me. 
2. Nephrodium nemorale Sodiro, Cr. vase. quit. 267. 1893; Dryopteris nemoralis 
C. Chr. Ind. 279 — Ecuador. 
3. Polypodium Urbani Sod. 1. c. 301; Dryopteris Urbani C. Chr. Ind. 299 — Ecuador. 
4. Aspidium hemiotis Christ, Hedwigia 45: 191. 1906 — Amazonas. 
Subgenus 10. Meniscium (Schreber). 
The old genus Meniscium is a well-known and apparently one of the most 
distinct groups of ferns. The species from the Old and the New World referred to 
it are, however, certainly not very close relatives, and I now firmly believe that 
they are even not congeneric, and, moreover, that the American species can not be 
generically separated from Goniopteris. In this view I agree with MrETTENIUS (see 
Fil. Lechl. II. 19). Within the second group of Goniopteris, Eugoniopteris, we find 
an unbroken row of species, from free-veined species to such species as D. Ghies- 
breghtii and D. meniscioides, the venation of which is perfectly meniscioid. The other 
important character of Meniscium: the confluent sori, also is insufficient as distin- 
guishing mark between Goniopteris and Meniscium. Two species as D. meniscioides 
and D. ensiformis described below are really so closely related that it should be 
very unnatural to place them in two different genera. Still I have failed to find 
stellate hairs in all species of Meniscium and this together with the whole uniform 
character of the species justify the segregation of the species from the subgenus 
Goniopteris and the referring of them to a proper subgenus, Meniscium. If one should 
prefer to separate both these subgenera from the others, they should certainly be 
united into a single genus. 
The Old World's species of Meniscium, as commonly understood, are con- 
siderably different from the American ones, and I have no doubt that they must 
be referred to Cyclosorus being a specialized group of that subgenus. Thus the two 
subgenera (or genera) Cyclosorus and Goniopteris includes each a series of species, 
from free-veined forms to such having meniscioid venation. The American species 
of Cyclosorus do not show a venation intermediate between the simple, goniopteroid 
venation of D. mollis and meniscioid veins, but such forms we find in Asia. I shall 
here only refer to such forms as Polypodium urophyllum Wall. and Meniscium cu- 
spidatum Bl. 
My material of the American species of Meniscium is not so comprehensive as 
that of the other subspecies of Drygopleris. I can not, therefore, give here a review 
of the- species. The group is represented in America by perhaps a dozen species,
