 Aspid. Desv. Hk. Sp. 4. p. 46. A. trifoliatum, A uct. (in part}. 



Hab. Mauritius and Bourbon. Differs from A . trifoliatum by its ebeneous stems and

 side, the lowest 3-4 in. 1., long-stalked, deltoid, cut down below into dis- 

 tinctly separated, deeply pinnatifid pinnl. with blunt linear-oblong lobes ; texture 

 subcoriaceous ; veins beneath prominent, anastomosing principally in large 

 costular arches ; areolce large, with free included veinlets, depressed so as to 

 form a cavity, in which on the end of the free vein the large copious sori are 

 placed. Asp. Kze. A. immersum, Hk. Sp. 4. p. 58. Phlebigonium, Fee.

 pairs of lateral pinnce, the lowest much the largest, sometimes cut down to the 

 rachis at the base with a deeply pinnatifid pinnl. ; texture papyraceo-herbaceous ; 

 primary veins distinct ; areolce rather large, with free veinlets ; sori large, in 

 rows near the veins, terminating free veinlets. Asp. Wall. Hk. Sp. 4. p. 51. 



Hab. N. India and Malaya. This has quite the habit and texture of N. subtriphyllum, 

 differing in sori and venation.
