Ferns of British India and Ceylon. 317 



* Fronds pin?iatifid or somewhat pinnate at the base only. 



1. Goniophlebium A3VLENUM. {Wall.) Caudex creeping, 

 stout, densely paleaceous, with ferruginous subulate scales, which 

 are sub-adpressed, never hair-pointed ; stipes a span to a foot or 

 more long, stramineous or brown ; fronds 1 to nearly 2 feet long, 

 6-10 inches wide, glabrous or sub-pubescent, ovate, terminating in a 

 lanceolate acuminate subentire segment, deeply pinnatind to within 

 2-3 lines of the costa, segments horizontal, more or less approximate, 

 3-8 inches long, £-4- inch wide, subfalcate from a broad base, 

 ensiform gradually acuminate, entire, or coarsely dentate-serrate, 

 lowest pair deflexerl, veins forming one costal series of moderately 

 sized soriferous areoles, and sometimes two (the second not sori- 

 ferous), marginal veinlets free, soriferous veinlet always arising from 

 the vein at a distance from the costa ; sori subglobose sunk (papil- 

 lose on the upper s ; de.) Hook. Sp. Fil. v. 24. Wall. Cat. 11. 290. 

 Bedd. KB. L t. 5. 



Himalayas, from Gurwhal to Bhotan, 4,000-11,000 feet ele- 

 vation, common ; Khasya 3,000-6,000 feet. (Clarke's var. 

 tonglensis from Tonglu near Darjeeling, appears only to differ in 

 the pinnae being blunt at the apex, there is, however, only one poor 

 specimen known of it.) 



2. Goniophlebium subama:num. {Clarke) Rhizome slender, 

 densely clothed with grey-brown lanceolate-subulate scales, which are 

 subadpressed, never hair-pointed, near the base of the main rachis 

 are sometimes ovate or lanceolate scales ; stipes about 2 inches long ; 

 fronds 6 inches long, deeply pinnatifid nearly to the rachis, lower 

 segments much abbreviated and deflexed, all serrated at the margins ; 

 costal arches of the main rachis continued nearly or quite to the base 

 of the frond ; main rachis above glabrous or puberulous. Clarke, 

 F. N. I. p. 550, t. 82,/ 2. 



Very nearly allied to amocnum, and perhaps only a form of it, 

 differs in its slender rhizome and small size. 



Himalayas, on the ridge between Sikkim and Nepal, 11,000- 

 1 2,000 feet elevation, very abundant.
