Related rather to Schizoloma, gnerinianum Gaudich., than to S. cUvergens 
(Wall.) Diels, which has comparatively long and narrow pinnae and pale foliage. 
The pinnae are articulate to the rhaehis, but rarely separate from it. About one 
pinna in ten shows an anastomosis of veinlets. It is smaller than S. pellaeiforme 
(Christ) Christen. {Lhidsaya pellaeiformis Christ, Fil. Saras. 287 ; Ann. Jard. Bot. 
Buitenz. 15 (1898) 102. pjl. IJ^. f. U/.), and has comparatively much deeper pinnae.

A distinct species, but of rather uncertain generic affinity. Athyrium seems 
to me the most natural place; but ferns I can not distinguish from Nephrodium 
distans (Don) Diels sometimes have athyrioid indusia.

A very distinct species, conspicuous in the field for the pubescent appearance 
of the upper surface, caused entirely by the very sharp, elevated or reflexed teeth.
