Rhizome short, oblique, densely scaly and setose hairy ; scales lanceolate, rufo- 
brown, rigid, opaque, provided with gray, needle-like setose hairs on the margin; 
fronds cespitose, stipe 12-30 cm long, angular, straminous, sparcely scaly at base, 
setose hairy throughout the rachis, lamina deltoid to oblong-ovate, 15-30 cm long, 
12-18 cm broad, deeply pinnatifid to pinnate under the deltoid acuminate pinnatifid 
apex, base cordate; pinne free, 1-6-jugate, sessile lanceolate, 8-10 em long, 2.5-4 
cm broad, entire or slightly wavy, acuminate, base rounded, densely setose hairy 
underneath, sparcely and shortly so above; texture harsh-herbaceous, opaque upon 
drying; lateral main veins distinct to the edge, intervening veinlets anastomosing 
in 8 rows of hexagonal or quadri-angular and exappendiculate areole; sori inde- 
finite, reticulated, following the course of veinlets; sporangia globular, shortly 
Stalked, provided with a few setose hairs near the top.

A peculiarly distinct genus of one single species with pinnatifid or pinnate 
fronds. Hemionitis Wilfordii represents a pinnatifid form of the fully pinnate 
Himalayan type; both forms are often seen from the same locality. The affinity of 
the genus to Bolbitis Schott and Stegnogrjamma Bl. seems to be most probable.
