A species related to D. flaecida (Forst.) Bernh., of Samoa, characterized by 
its long and rather frequent villous hairs, the pinnules of the third order broad, 
irregularly parted and serrate-imbrieate, and a rather pronounced dimorphism 
between the fertile and sterile fronds. Texture thin. Racliis and costae covered 
with a reddish pubescence. It is distinguished from D. flaecida by its lobes and 
pinnules being narrower and in its shorter pubescence, otherwise very similar to 
that species.
