Fronds pinnate; leaflets alternate, linear, smooth, entire, 

 emarginate, fertile and barren alike. 



Nat, of the Delta of the Ganges. Fructifies in the rainy 

 season. 



Roots fibrous, issuing from a firm, subrotund head, even 

 with the earth, round which the stipes are attached. 



Stipes in bundles, straight, smooth, polished, green, with 

 remote thorny points on the margins of the furrow, which runs 

 up the forepart ; length about one, or one and a half foot. 



Fronds pinnate, from 2 to 4 feet long, leaflets generally 

 alternate, about 12 or 14 on each side, short-petioled, linear, 

 entire, smooth, emarginate, /l^r/i/^ leaflets like the abortive, 

 and are the most exterior; general length about 6 inches, 

 and about 1 broad.

Fronds pinnate, (12 inches high,) the barren pinnas alter-

 there enlarged at the upper angle ; fertile pinn^ very minute, 

 linear-oblong, on distinct stipes which are rather longer than 

 those of the barren fronds. 



Nat. of the Malay Islands. 



7. A. seetacoonense, R. 



Fronds (18 inches high,) suboppositely pinnate ; bar-
