Province of Zaniboanga, San Ramon {Copeland) May, 1905, alt. 850 in. 
A species related to D. flacdda (Forst.) Bernh., of Samoa, characterized by 
its long and rather frequent villous hairs, the pinnules of the third order broad, 
irregularly parted and serrate-imbricate, and a rather pronounced dimorphism 
between the fertile and sterile fronds. Texture thin. Rachis and costse covered 
with a reddish pubosconee. It is distinguished from D. fUwcida by its lobes and 
pinnules being narrower and in its shorter pubescence, otherwise very :^imilar to 
that species.
