The species, now found to be common in the localites cited, resembles D. hirti pes 
(Bl) O. Ktze. in general habit, to which it has generally been referred, from which, how- 
ever, it differs in exindusiate sori, fewer and more distant lateral pinne with crenato- 
cuspidate serrature, thinner texture and sparingly fibrillose-scaly rachis and upper part of 
stipe. D. hirtipes (Bl.) has never been found in China, Himalayas and Tonkin and its 
report therefrom by authors in the past has chiefly been a mistake for the present fern.
