 Hab. Tropical America, from Cuba and Mexico southward to Brazil and Peru ; Ceylon

 fr. 3-6 in. 1., 1-1^ in. br., with 12-18 pinnce in each side, which are J- j in. 1., 

 2-3 lin. br., bluntisb at the point, almost dimidiate, the upper edge inciso-crenate, 

 and narrowed suddenly at the base ; texture thinly herbaceous ; rachis slender, 

 green, compressed ; veins distant, once forked ; sori linear, oblique, falling short 

 of the edge, sometimes 1 or 2 almost parallel with the midrib on the lower side

 Fiji ; Mauritius, Seychelles, Bourbon, Angola, and Guinea Coast. — Sometimes the lower

Hab. Tropical America, from Mexico and Cuba southward to the Amazon. — Probably 

 this should be joined with the preceding, but the texture is usually firmer, and the pagina 

 is more developed on the lower side of the midrib, as in the cristatum form just 

 mentioned.
