Rhizome short, erect, densely radicose, together with the stipe densely clothed in rufo-brown broadly 
ovate, caudate and fimbriate scales; fronds caespitose, stipe 8-10 cm long, rufo-stramineous, clothed in similar 
and persistent scales intermixed with some lanceolate-subulate ones of a brown color, lamina 30-35 cm long, 
23 cm broad, linear-lanceolate, gemmiferous and often radicant at about 4 cm below the apex, pinnate; 
pinnae 40-50 pairs, pectinately imbricate, subsessile, lower ones deflexed and slightly abbreviated, the middle 
ones 1.6 cm long, 7 mm broad at the base, triangular, aristately acute, base roundly cuneate below, and trun- 
cate above with a large deltoid aculeate-aristate auricle, margin repand, subentire with a few low stout 
decumbent teeth; zexture coriaceous, dry brown, rachis scaly, under side with sparse, lanceolate appressed 
scales especially in the young state; veins confert, forked, but pinnate in the auricle, distinctly impressed 
below, obscure above; sori small, medial between the margin and costa, terminating the anterior veinlet of 
each group, indusium round, entire, fallen off at last.

A very distinct and common fern in the wooded mountains in Southwestern China, westwardly to 
Upper Burma and Sikkim, where the species seems often to grow together with Polystichum Atkinsoni Bedd, 
The plant from Taiwan as figured by Ogata is typical of the species. The Japanese plant proves essentially 
the same, except smaller, the same form being also seen from West China.
