brown, thin, clathrate, ovate, acuminate, fallen off at last; frond 2-3 cm apart, 
lanceolate, 10-20 cm long, 2-3 cm broad, gradually attenuate upwards, suddenly narrow- 
ed at base, thence decurrent either nearly down to the base of the short stipe, or leaving 
a rather distinct wingless stipe to 3 cm long, margin often slightly wavy; texture firmly 
chartaceous, color brownish; veins hardly visible but distinct under strong light; sovi 
small, scattered over the entire under surface, naked.

A very common fern in South China, particularly in the province Kwangtung; 
generally epiphytic on the trunk of trees or over rocks under forests. Authors on 
Chinese and Japanese ferns have generally taken this for Malayan Polypodium super- 
ficiale Blume, with which it has in fact little in common, except the general outline. To 
M. hymenodes (Kze.) this species is very closely related, differs but in suddenly narrow- 
ed leaf-base, thicker texture and consequently less visible venation, and in smaller, 
denser sori.
