Rhizome short, the scales brown, narrowly subulate, subentire. Stipes 

 ±15 cm. long, densely scaly like the rachis; scales partly long, subulate, 

 spreading, reddish-brown, entire, partly minute, subadpressed, irregularly 

 fimbriate, ferrugineous. Fronds lanceolate, 45 cm. more or less long, + 

 15 — 20 cm. broad at the middle, acuminate. Pinnae somewhat remote, 

 spreading or horizontal, to + 10 cm. long and 1 '/, cm. broad, acute, the 

 lower gradually abbreviated, deflesed, more remote. Pinnulae linear- 

 oblong, approximate, nearly horizontal, the largest + '/^ — 1 cm. long by 

 ± 3 — 4 mm. broad, connected at the base by a very narrow wing, 

 subentire or indistinctly crenulate or hardly toothed, the apex rounded 

 or truncate, the base broadly adnate; lowest pinnulae rather narrowly 

 adnata at the base. Texture subcoriaceous ; surfaces sparingly flbrillose 

 or hairy on the costulae and veins; costae (secondary rachises) fibrilloso- 

 pilose above, scaly beneath; costulae flexuose; veins simple or forked. 

 Sori medial; indusium reniform, persistent, at length deflexed and 

 crisped. — An alpine species.

Fronds 2-pinnatifld, probably 2-pinnate at the base, the apex acuminate, 

 deeply pinnatifld, the main rachis livid-brown, rather naked l^eneath and 

 deciduously flbrillose above, as are the costae. Pinnae ascending; central 

 pinnae alternate, shortly petiolate, hnear-lanceolate, +11 cm. long, ± 

 2'/, cm. broad, broadly cuneate and unequal-sided at the base, the upper 

 base the broadest, the edge cut down nearly to the costa; lower pinnae 

 probably pinnate. Secondary segments ascending, linear, subfalcate, ± 

 l*/4 cm. long and 4 mm. broad, approximate, acute, somewhat narrowed 

 near and slightly dilated at the base, the lowest anterior the largest,
