Hab. Sandwich Islands ; in moist shady forests ; frequent. 



Although very distinct, this nevertheless possesses a habit and 

 aspect a good deal like the preceding species ; but on examination it 

 is readily recognised by its densely paleaceous stipes, larger fronds, 

 broader segments, and the reniform indusium seated on the costa of 

 segments, not on the teeth.

(Asplenii Spec. Linn. & Auct.) 



Presl, in his Tentamen Pteridographige, divides the genus Asple- 

 nium into two sections ; the first section, " Thamnopteris" embracing 

 only the A. Nidus of Linnaeus. On this and some other closely allied 

 species Mr. J. Smith subsequently founded the genus Neottopteris ; 

 and we are also of the opinion that they ought to be separated from 

 Asplenium, on account of the apices of the venules being combined 

 by a transverse marginal vein.
