^ Fronds pinnatifid or somewhat pinnate at the base only. 
1. GoNioPHLEBiUM AM^NUM. ( Wall.) Caudcx 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 i to nearly 2 feet long, 
6-10 inches wide, glabrous or sub-pubescent, 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- 8 inches long, \-\ inch wide, subfalcate from a broad base, 
ensiform gradually acuminate, entire, or coarsely dentate-serrate, 
lowest pair deflexed, 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 sMe.) Hook. Sp. Fil. v. 24. Wall Cat. n. 290.

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 pinn?e 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, /. 82,/ 2. 
Very nearly allied to amsenum, 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- 
12,000 feet elevation, very abundant.
