Rhizome short, oblique, densely scaly at apex; scales small, brown, ovate- 
acuminate, subentire; fronds cespitose, 10-18 together, stipe to 13 cm long, 
straminous, terete, firm, sparcely clothed in small, ovate-acuminate, uniform 
scales, lamina slightly oblanceolate, 15-25 cm long, 4-7 cm broad, acuminate, 
finely tripinnate; pinne numerous, close, alternate, subsessile, patent, lanceolate, 
2-3 cm long, lower ones somewhat shoitened and deflexed; pinnules 6-12-jugate, 
oblong-ovate, base long-attenuate and decurrent along deeply grooved and nar- 
rowly winged costa; wltimate pinnules 2-3-jugate, generally deeply bifid into linear- 
subulate uni-nerved segments, hardly over 1 mm broad, with sharp point; texture 
herbaceous, green, underside sparcely scaly; sori small, one to each segment, 
terminating the veinlet some distance below the apex of segment, indusium 
large, rounded, membranaceous, as brcad as segment, soon falls off.

This is one of the most distinct species of the group of Polystichum from 
West China and Himalaya, which is characterized by finely dissected fronds with 
linear-subulate uni-nerved entire and sharply pointed ultimate segments. 
P. alcicorne (Baker) from the same locality is a very close relative, which differs, 
however, in more coarsely dissected frond of a much stouter habit and in the 
presence on the stipe and rachis underneath of the large ovate, sO SO DEINE aT 
brown persistent scales.
