lanceolatis, obtusis, usque ad 7 cm longis; pinnulis u majoribus brevistipi-

Very near the Indian species, P. cyatheoides Don, but differing from that as 
described and figured, in the broader paleae, more dissected frond, and nowhere 
glabrous pinnules, and the sori much larger in proportion to the fertile pinnae. 
Specimens from western China, leg. Wilson 5371f are referable to the Indian 
species.
