Rhizome epigaeous, wide-creeping, densely shaggy scaly; scales rufo-brown, clath- 
rate, iridescent, broadly ovate, cuspidate or gradually attenuate with long subulate and 
spreading apices, margin with long or short teeth; frond rather close, stipe short, 
generally 6-10 cm long, naked, straminous, lamina narrowly lanceolate, 30-50 cm long, 
about 7 cm broad, pinnatifid down quite to the rachis into numerous, spreading, close, 
remotely crenato-serrate, subacuminate pinnae, texture papyraceo-herbaceous, glabrous 
above, densely scaly and sparcely hairy along rachis and costa underneath; veins hardly 
visible but distinct against light, areolae uniseriate; sori in a single row on each side of 
costa, densely scaly when young.

A very slender fern, endemic in the Himalayas, characterized by relatively short 
stipe and narrowly lanceolate, elongate lamina, dark-colored almost orbicular or ovate 
dense, finely reticulate scales having a long cuspidate or setiform spreading point, and 
consisting of large, clear, iridescent luminae. The sparcely pubescent underside of leaves 
may be a cause of confusion with the pilose form of P. amoenum, common in Yunnan 
and other parts of West China, which differs, however, in much broader leaves, decidedly 
stouter habit and thicker texture.
