Polynesia. 



A species still niore pubescent than the preceding, and a third or one-half 

 smaller, fronds somewhat abrupt below by the pinnae gradually becoming shorter, 

 but witliout auricles, the pinn.ne soniewhat distant, narrow, t])e lobes triangular, 

 the texture niore coriaceous, the color a light yellowisli green. Nerves forn)ing 

 one areola, the sori larger, brownish, the sporangia hairy. I have identified the 

 above specimens with this species after the description given by Baker in Synopsis 

 Filicum 290 under Nephrodiiim imismn Carruth. Gopeland in his Polypodiacefe 

 of tlie Philip))ines, 30, accepts this species, and repeats Baker's description with 

 a slight n)odification "sori in rows close to the midribs," while Baker says "sori 

 midway between the midrib and edge," the latter being tlie case with our 

 s])ecimens. Baker also says "common in tlie Polynesian Islands." I have but 

 one specimen from the Solomon Islands leg. Betche, w])ich agrees weil witii t])e 

 description, but in wl)icl) t])e base of the frond is abrupt, not narrowed, and witli 

 one auricie on tlie stipe. A critical species.
