Hab. Kauai, Sandwich Islands : on open mountain ridges. 



Plant tufted, from 25 to 30 fronds in a tuft. Rootstock globose 

 and densely imbricated with slender, attenuated, black, reticulated 

 scales. Stipes one to 3 inches long, and a little thicker than the quill 

 of a sparrow, of a dull brown colour, terete, margined. Fronds 10 to 

 12 inches high, erect, linear-lanceolate, rather rigid, and bipinnate to 

 the very apex. Pinnce alternate, sessile, spreading, from 8 to 10 lines 

 long, oblong-lanceolate, unequal at the base. Pinnides obovate or 

 oblong, obtuse; the lower and terminal one the largest and deeply 

 pinnatifid, outwards bifid or trifid; the 2 or 3 next the point entire 

 and falcate. Rhaclds margined throughout. Sori submarginal, solitary 

 on the superior or inner side of the pinnules, with an entire, oblong, 

 or lunate, somewhat coriaceous, straw-coloured indusium, which ex- 

 tends beyond the margin. 



This is closely allied to the A. ( Cosnopteris) rliizophyllum of Smith. 

 But the fronds are longer, narrower, more erect, and destitute of 

 bulbs at the point, while the pinnules are more contracted, and the 

 sori nearer to the margin than in that species.

Asplenium foeniculaceum, Humboldt & Kunth, ex Hook. & Grev. Ic. Fil. t. 92. 



Hab. Organ Mountains, Brazil. 



All the specimens in our possession are young, yet we feel satisfied 

 of its being the A. foeniculaceum of Humboldt and Kunth, as figured 

 by Hooker and Greville.
