We have some doubts as to whether the A. Martinicense of Will- 

 denow be specifically distinct from the present plant.

Hab. Sandwich Islands : in forests-. 



Stipes about 12 inches long, of a dingy brown colour, half-round, 

 with two ribs in front, hirsute with scattered slender pa leas, which ex- 

 tend to the rhachis. Fronds bipinnate at the base, and narrowing 

 gradually into a simply pinnate point. Pinnos with a petiole 6 lines 

 long, alternate, ovate-oblong and acuminate, pinnate or deeply pinna- 

 tifid at the base, and terminating in an incisely serrate point Pinnules 

 half an inch to an inch long, smooth, coriaceous, striate on the upper 

 surface, obovate-cuneate and decurrent, the rounded point doubly-toothed. 

 Secondary rhachis compressed and, with the primary one, proliferous 

 on the upper side near the apex. Veins radiating from the base of the 

 pinnules, and forking once or twice before reaching the margin. Sori 

 4 to 6 on each pinnule, long, linear, and diverging from the evanescent 

 costa. Indusium coriaceous, entire, of a light brown colour.
