Hab. Tahiti, Society Islands. 



Stipe smooth and of a straw-colour. Frond membranaceous, bipinnate. 

 Pinnules oblong -lanceolate, petiolate, sinuately pinnatifid, cordate at the 

 base; the segments oblong-lanceolate, acuminate, and somewhat repand. 

 Sori small and scattered. 



In the outline of the segments a considerable variety of forms is 

 found to exist. Mr. John Smith, in his Enumeratio Filicum Philip- 

 pin arum, refers this species to the genus Aspidium of Schott. We 

 have searched in vain for what might be considered a proper indu- 

 sium, but find nothing resembling it ; neither can we detect any cha- 

 racter that would warrant the removal of the plant from Drynaria, as 

 that genus is now characterized.
