POLY PODIACEAE 
LEPISORUS SUBOLIGOLEPIDUS Ching, Bull. Fan Mem. Inst. Biol. 4: 77 (1933). 
Polypodium neurodioides C. Chr. var. 2. C. Chr. Contr. U. S. Nat. Herb. 26: 319 (1931). 
Rhizome creeping, thick, densely scaly; scales as in L. Thunbergianus (Kaulf.); 
frond rather distant, 20-30 cm long, 2-3 cm broad, lanceolate, long-attenuate towards 
apex, the broadest part being at the lower one-third, densely scaly on the under side 
and stipe; texture rigidly chartaceous or subcoriaceous; sovi medium-sized, medial, con- 
fined to the upper part of lamina. 
Yunnan: Mile District, A. Henry 10988A (type); between Tengyueh and Lung- 
ling, J.f. Rock 7113, on tree. 
Quite a distinct species, habitally resembling L. oligolepidus (Baker), differing in 
thinner texture, long-attenuate leaf-apex and the broadest part of the lamina being at, 
the lower one-third, as well as in much smaller medial sori.
