24 POLYPODIUM, § GONIOPHLEBIUM. 



Ilab. On trees, Panama, Seemann, n. 25. — Habit of P. trilobum of Chili, and 

 P. ensiforme of the Cape, but quite different from both. 



266. P. (Goniophlebium) attenuahim, H. B. K.; caudex 

 stout short creeping paleaceous, stipes rather stout a span 

 and more long reddish-brown, frond coriaceo-membranaceous 

 10 inches to 2 feet long 8-10-12 inches broad subdeltoid- 

 ovate acuminate deeply to the rachis pinnatifid leaving only 

 a very narrow wing at the broad sinuses, segments very dis- 

 tant elongato-lanceolate acuminate or obtuse entire 4-6 

 inches long \ an inch to nearly an inch wide usually at- 

 tenuated at the base and slightly decurrent, terminal one 

 similar to the rest sometimes bi-trifid, veins forming three or 

 four series of areoles of which the costal ones and frequently 

 the next series are soriferous, sori subrotund. — H. B. K. in 

 Wi/hl Sp. PL y.p. 191. Kze. in Linnaa, xxi. p. 219. P. 

 dissimile, Schk. Fil. p. 14. /. 14. P. xiphophoron, Kze.

 Fee. 



Hab. Tropical America: Caripe, Humboldt; Venezuela, Fendler, n. 490; 

 Guiana, abundant, Parker, R?c/iard Schomburgk, n. 1669, Robf. S., n. 460, Le 

 Prieur ; Brazil, Spruce, n. 736; Orinoco, Spruce, n. 3575; Central America, 

 Cumin;/, n. 1265 ; Ecuador, Jameson, n. 565, Seemann, n. 980. — I think a well- 

 marked species, well figured by Schkuhr, but which Mettenius seems to confound 

 with P. (Eupolypod.) sororium, which has free venation and oblong sori. 



267. P- (Goniophlebium) amcenum, Wall. ; caudex creep- 

 ing densely paleaceous with ferruginous subulate scales, sti- 

 pites a span to a foot or more long stramineous or brown, 

 fronds 1 to nearly 2 feet long 6-10 inches wide glabrous or 

 subpubescent ovate terminating in a lanceolate acuminate 

 subentire segment, deeply pinnatifid to within 2-3 lines of 

 the costa, segments horizontal more or less approximate 

 3-6-8 inches long ^-^ an inch wide subfalcate from a broad 

 base ensiform gradually acuminate entire or coarsely dentato- 

 serrate, lowest pair deflexed, veins forming one costal series 

 of moderately sized soriferous areoles and sometimes two 

 (the second not soriferous), marginal veinlets free, soriferous 

 veinlet always arising from the vein at a distance from the 

 costa, sori subglobose sunk (papillose on the upper side). — 

 Wall. Cat. n. 290. Metten. Polyp. p. 80. Marginaria, Pr. Go- 

 niophlebium, /. Sm. 



Hab. Nepal, Br. Wallich, and Khasya {Griffith), and northern and north- 

 western India, Bootan, Kumaon (alt. 6000-8000-10,000 feet), etc., Hooker and 

 Thomson, Lady Dalhousie, Edgexmrth, Col. Bates, and others. Mussoorie, Dr. 

 Bacon. — This may assuredly be considered the representative in India of the P.
