1%. Polypodium fimbriatum Maxon, nom. nov. 
Polypodium villosum Karst. Fl. Columb. 2: 87. 1865-69, not L. 17538, Dulae, 
1867, nor Fée, 1872-73. 
TYPE LocaLity: “ Valador de Fuquene,” Cordillera of Bogotaé, Colombia, alti- 
tude 2,900 meters. 
DISTRIBUTION: Mountains of Colombia. 
ILLUSTRATION: Karst. op, cit. pl. 144. f. 1-7 (as P. villosum). 
Known to the writer only from the Lehmann specimen cited below, listed by 
Hieronymus* as P. villosum. This is only about half the size indicated by 
Karsten’s large illustration, but in its minute morphology it agrees absolutely 
with the excellent detailed figures. Unfortunately the name Polypodium vil- 
losum is invalid because of its earlier use for the large tropical American species 
now known as Dryopteris villosa (L.) Kuntze. The above new name, P. jimbri- 
alum, is therefore suggested. 
Mettenius* cites two additional Colombian localities for this species, and 
Christensen ascribes it also to Venezuela and Peru. Lehmann’s specimen, above 
mentioned, is: 
Cotompra: Near Facatativa, Province of Cundinamarca, alt. 2,600 meters, 
on sandstone rocks, Lehmann 2456. 
DOUBTFUL SPECIES, 
1. PoLypopruM LANOosUM Fée, Gen. Fil. 237. 1852. 
According to Christensen’s Index Filicum, Fée’s Polypodium lanosum, de- 
scribed from Chile, is referable to P. lepidopteris var. rufulum. If it should 
prove to be distinct and not to have been described under some other name 
since 1852, it must be renamed, on account of the earlier Polypodium lanosum 
Poir. (1804), applied to other plants. 
2. POLYPODIUM LONGICAULE (Fée) CG. Chr. Ind. Fil. 326. 1905. 
Judging from description this species, published originally as Goniophlebium 
longicaule Fée,* is of the P. squamatum group. It does not appear to have been 
mentioned by recent authors and is wholly unknown to the writer, The original 
specimens are from Rfo Hacha, Colombia, Schlim 847, and the species is 
ascribed only to Colombia. 
3. POLYPODIUM VEXILLARE Christ in Schwacke, Pl. Nov. Mineiras 2: 21. 1900 ; 
Bull. Herb. Boiss. II. 2: 873. 1902. 
Founded upon specimens collected by F. Miiller in Santa Catharina, Brazil. 
Though given a binary name it is described by Christ as a subspecies of P. lepi- 
dopteris, having the “ general aspect of P. moniliforme or of very small P. fur- 
furaceum.” It was collected also by Ule in the same region. Not seen by the 
writer.
