Polynesia. 
A species still more pubescent than the preceding, and a tliird or one-half 
i 
smaller, fronds somewhat abrupt below by the pinnje gradually becoming shorter, 
but without auricles, the pinjta; somewhat distant, narrow, the lobes triangular, 
the texture more coriaceous, the color a light yellowish green. Nerves forming 
one areola, the sori larger, bro\\-nish, the sporangia hairy. I have identified the 
above specimens with this species after the description given by Baker in Synopsis 
Filicum 290 under Nephrodium hwisum Carruth. Copeland in his Polypodiaceae 
of the Philippines, 30, accepts this species, and repeats Baker's description with 
a slight modification "sori in rows close to the midribs," while Baker says "sori 
midway between the midrib and edge," the latter being the case with our 
specimens. Baker also says "common in the Polynesian Islands." I have but 
one specimen from the Solomon Islands leg. Betclie, which agrees well with the 
description, but in which the base of the frond is abrupt, not narrowed, and with 
one auricle on the stipe. A critical species.
