I am literally overwhelmed with specimens of this plant from almost all 

 the tropical parts of the world, and il' the peculiar structure of the fronds 

 be considered and allowance made for the usual variations, so general among 

 ferns, it is an easily recognized species. 



38. G. Klotzsc/iii, Hook.; stipes rounded, ultimate branch- 

 es with a pair of pinna; and a pair also at the base of the di- 

 chotomy, pinnie elongato-lanceolate acimiinate pinnatifid, 

 segments linear acute coriaceous glabrous glaucous beneath 

 where the costa is clothed with long ferruginous hairs, lower 

 external segments the smallest quite entire, capsules 4 — 6.

Hab. Brazil, Sellmv. — Perhaps this ought rather to be considered a va- 

 riety of the preceding than retained as a distinct species. My specimen is 

 but imperfect; but it evidently belongs to this section. The pinns are 

 about a foot long, rigid, coriaceous- The chief character of the species, if 

 species it may be called, lies in the copious long dark ferruginous hairs 

 which clothe the rachis of the segments beneath.
