1. D. simplicifolia, Rudge ; st. of the barren fr. 2-12 in. 1., with 0-2 nodes, 

 slightly scaly below ; barren fr. 6-12 in. 1., 2-4 in. br., ovate-oblong, the apex 

 acuminate, the edge entire, the base' rounded or cuneate ; texture subcoriaceous ; 

 midrib beneath naked ; veins close, usually once forked ; fertile fr. similar but 

 smaller, and the st. longer. Rudge, t. 36. Kunze, t. 50. 



Hab. Guiana and North Brazil. One of our specimens is partially fertile only. There 

 are about 100 capsules in the central synangia, and 30,000 to an entire frond.

 scaly below ; barren fr. with an oblong-lanceolate entire terminal pinna 8-12 

 in. 1., 3 in. br., and one or two pairs of similar but smaller lateral ones ; texture 

 coriaceous ; surfaces glossy, the rachis naked, not winged, swollen at the nodes ; 

 veins close, usually once forked, casually anastomosing ; fertile fr. on a longer^., 

 the pinnae smaller. Kze. Anal. 4. t..2.
