 acuminate, the edge slightly toothed towards the point, the base rounded equally 

 on both sides ; texture very coriaceous ; rachis strong, erect ; veins simple, close, 

 parallel ; sori beginning at the midrib, but falling short of the edge. Hk, Sp. 3.

 zium, Fee, Gen. Fil. 214. Fil. Ant. tab. 10. fig. 2. 



Hab. Cuba, Linden ; Guadeloupe, L'llerminier ; Tarapota, Peru, Spruce, 4760. This 

 rivals Lechleri in size and texture, differing totally in venation.
