Oss.—This genus consists of the following species, all 
natives of India, China, Malayan Peninsula and Islands, 
The first, D. piloselloides, has the sorus when young fur- 
nished with stellate pubescence, similar to Niphobolus, 
while D. carnosum has the line of sporangia covered with 
orbicular scales, analogous to Hymenolepis. This difference 
led Presl to characterise this latter species as a distinct 
genus, under the name Lemnophyllum, but I do not think 
the character is of sufficient importance to warrant its 
adoption as a genus. 
Sp. D. piloselloides (Linn.) (v v.) ; D. carnosum ( Wall.) 
(Lemnophyllum, Pr.) ; D. Cunninghami, Moore (D. carnosum, 
J. Sm. non Wall.); D.? rigidum, Hook. Sp. Fil. Ic. Pl. t. 
996. This is a native of Borneo, and on account of its 
having no free veinlets, is probably not a true Drymoglossum. 
Moore refers it to Schizolepton.
