I (1807). 
Rhizome thick, creeping, densely scaly; scales shaggy, ovate-acuminate, den- 
ticulate, fuscous, concolorous, finely clathrate with medium-sized but clear, uniform 
lumine; frond rather approximate, narrowly linear-elongate, margin strongly revoluted, 
25-35 cm long, about 5 mm broad, gradually decurrent to the base; texture rigidly 
coriaceous, color greenish, sparcely scaly beneath; sori ovate, closely packed between the 
midrib and the revoluted margin, which completely conceals the sori, when young, and 
becomes somewhat dilated due to the expanding sori.

One of the most distinct fern of the genus Lepisorus, being unlike any other 
known species, except L. Lewisii (Baker), which is also provided with narrowly linear 
fronds with strongly revoluted margin and more or less concealed sori, but differs in 
decidedly smaller size, and entirely different type of scales on the rhizome.
