China, and Formosa.* From China the following specimens have 
been examined :—

17. P. hymenodes, Kunze. 
The identity of Wallich’s P. hymenodes with Leptochilus 
axillaris, Kaulf. perhaps requires no commen 
Kunze’s P. hymenodes, on the other hand, has long been 
unrecognised, and, according to Christensen’s Index Filicum, 
it is regarded as a synonym of P. superficiale B1.t It is, however, 
difficult to understand why such a mistake has arisen. Even a 
glance at Blume’s excellent figures of P. superfictale, Bl. and 
Mettenius’ careful illustrations of P. hymenodes, Kze. is sufficient 
to make out the distinction between these two totally distinct 
species. 
Our plant resembles P. normale, Don in having a thin ob- 
lanceolate frond, which is acuminate at the apex and towards the 
base gradually decurrent into a very short stipe, and in having 
the sori irregularly scattered over the greater part of the under- 
surface of the frond. It can be, however, distinguished from 
the other by the nature of the ramenta on the rhizome, which 
are ovate-lanceolate, long-acuminate, ciliate-denticulate on the 
margin, and bear no bristles on the back. 
The frond of the typical form of this species bears sori 
scattered over the whole under-surface, whilst that of the variety 
has sori situated near the margin, leaving a naked portion 
along the mi 
This species is is distributed over the northern parts of India, 
Western China, Melanesia, and Formosa. The synonymy and
