POLY PODIACEAE 
LEPISORUS PSEUDONUDUS Ching, Bull. Fan Mem. Inst. Biol. 4: 83 (1933). 
Rhizome wide-creeping, densely scaly; scales ovate-lanceolate, acuminate with 
rounded base, margin with protruding teeth, concolorous, fuscous, clathrate with large, 
clear, rather uniform luminae; frond about I cm apart, 20-25 cm long, about 1.5 cm 
broad, elongate-oblanceolate, gradually attenuate to a short but distinct stipe, apex 
caudato-acuminate, quite glabrous on both sides; texture subcoriaceous: venation com- 
pletely hidden; sori medium-sized, rounded, medial, extending halfway downward.

A well marked fern, somewhat resembles L. nudus (Hooker) in general habit, 
differs, above all, in dense, spread, fuscous, lanceolate, long-acuminate scales with 
dentate margin, clear, quite uniform lumine, and in rather suddenly caudato- 
acuminate leaf-apex; from L. loriformis (Wall.) it differs in oblanceolate, stipitate leaves 
with suddenly caudato-acuminate apices and rounded medial sori. 
This is a common fern in the mountains in western Szechuan and Yunnan and 
generally considered by previous authors as Polypodium lineare Thbg., or some other 
closely related species.
