margins entire a little reflexed, costule aTid veins quite im- 

 mersed not apparent, sori 7-9 in two rows near the margin, 

 rachis slightly i)roniinent Ijeneath less so on the upper side.

Ilab. British Guiana, Schomburgk, n. 1031. — A most distinct and apparently 

 rare species, for I liave never seen any specimens save tliose collected by Schom- 

 burgk. In a young state, the white pulveraceous substance probably covers the 

 upper as well as the under surface, and in age disappears, 



G.5. P. (Eupolypodium) KeffcJianum, Kze. ; "frond small 

 lanceolate rather obtuse attenuate at the base decurrent sub- 

 coriaceous opaque vcinless, on each side especially beneath 

 and at the thickish subreflexed margin fusco-pilose pin- 

 natifid, segments triangulari-ovate obtuse entire with patent 

 sinuses, sori about five near the margin, stipes very short 

 and as well as the ccespitose caudex ferrugineo-setoso-palea- 

 ceous.'' Kse.in Linncea, xxi. p. 210. Mdten. Polyp, p. 47- 



Hab. Surinam, Kegel. — " Fronds copious, hygrometric, recurved, 2 inches long, 

 2-4 lines wide, pale-green, somewhat pellucid." — " P. discolor, Hook. Ic. n. 386, is 

 nearly allied to this, but abundantly ditfers in being twice larger, the fronds ses- 

 sile, more linear than lanceolate, obtuse, powderv, while beneath, glabrous above, 

 opaque, the lacinia; are longer, narrowcM-, the sinuses acute, and the sori 7-8 in 

 each segment. No other known to us approaches it." Kze. 



66. P. (Eupolypodium) lan/fferiim. Eat., an Desv. ?; "cau- 

 dex crespitose, stipes 4 lines to 1 inch long cano-villose, 

 fronds 3-8 inches long all over subvillose with whitish hairs 

 which are at length rufidulous lanceolate attenuated at both 

 extremities here and there lengthening by itmovations pin- 

 natifid to the costa, segments distinct subcontiguous larger 

 ones in the middle 6-8 lines long l-H line wide from an 

 equal base or above a little produced elongato-oblong obtuse 

 entire, lower ones abruptly decreasing oblong or ovate ob- 

 tuse, the lowest ones abbreviated rotuiidato-ovate distant, 

 veins scarcely manifest, sori 8-12 on each side the costule 

 intermediate between the costule and the margin, capsules 

 here and there with a single seta." Metten. — Eat. Jul. Wright,

Hab. Peru, Hanke, Pappig ? Venezuela, Fendler, n. 212. — My specimens of 

 P. lanigerum of Kuuze, collected by Fctppig, and trom Klotzsch, and from Jur- 

 gensen (Mexico), I am disposed to consider small states of P. cullratum. Fend- 

 ler's plant seems (piite ditfereut from these, and has, I believe, been authenticated 

 by Mettcnius, whose character I give above; and it is of a more rigid texture.
