POLY PODIACEAE 
LEPISORUS HETEROLEPIS (Rosenstock) Ching, Bull. Fan Mem. Inst. Biol. 4: 86 (1933). 
Polypodium lineare var. heterolepis Rosenstock in Fedde, Repert. Sp. Nov. 12: 247 (1913). 
Rhizome creeping, epigaeous, densely scaly; scales lanceolate-subulate from a 
broadly ovate base, atratous, margin hyaline with numerous irregularly protruding 
teeth, luminae opaque, very narrow with thick, dark-colored walls; frond rather appro- 
ximate, linear-elongate, 20-27 cm long, to 5 mm broad, margin narrowly reflexed; 
texture coriaceous, color greenish; venation entirely hidden; sori oblong, far apart, closely 
packed between the midrib and margin, which is more or less undulated due to the 
expanding sori.

In habit this fern is exactly identical with the narrow-leaved form of L. 
loriformis (Wall.), called Polypodium subintegrum Baker, which differs in fuscous, ovate- 
acuminate, concolorous and coarsely clathrate scales with large, clear, almost isodiame- 
trical luminae. The affinity with L. subconfluens Ching is very great, which differs in 
close, or subconfluent, longer sori and hardly wavy leaf-margin.
