Rhizome hypogaeous, 2 mm thick, wide-creeping; scales sparce, dark brown, ovate, 
acuminate; frond distant, erect, stipe 10-14 cm long, naked, shining castaneous on the 
lower side and so is the rachis, lamina lanceolate, 22-30 cm long, 7-10 cm broad, simple 
pinnate; pinnae 20-30-jugate, patent, lanceolate, acute, distantly inciso-serrate, basal 
pinnae hardly abbreviated, but free from those next above, which are connected by a 
narrow wing along the rachis; texture membranaceous, green, lucide, naked on both sur, 
faces; veins distinct on both sides, areolae uniseriate, generally close, but some are open- 
particularly towards apex; sovi small, oblong, medial, far apart.

A pretty species endemic in the Himalayas. It differs from other species with 
goniophlebioid venation in almost membranaceous, lucide, naked leaves with castaneous, 
shining stipe, and the remotely inciso-serrate pinnae. The venation in this species is 
generally of goniophlebioid type, but some of the areolae are open, particularly towards 
the apex of pinnae.
