green, glabrous above, moderately fibrillose-scaly on rachis, petiole and costa beneath; lateral 
veins distinct, oblique, flexuose, intervening veinlets anastomosing in I-rowed angular

Hiamalayas: Simla District of Bashahr State, R. N. Parker 3018. 
Japan, common. 
A large fern of the habit of C. caryotidewm (Wall.), from which it differs in general- 
ly larger, oblong-ovate pinnz with rounded or rotundo-cuneate and almost equal-sided 
base without deltoid auricle, subentire margin from base upward and a few remote 
small teeth towards apex, and in inducium with subentire margin. A very common fern 
in West China from where I have seen numerous specimens.
