 throughout into blunt entire lobes with parallel sides, 2 lin. br. ; texture 

 herbaceous ; both surfaces pubescent ; veinlets simple, regularly pinnated ; sori 

 oblong, falling short of both edge and midrib, the lower ones curved. — Hk. Sp. 3.

Hab. Brazil, Lindberg, 620. — Very like the preceding in habit and cutting, but the

 subcoriaceous ; racliis firm, naked, proliferous ; veins conspicuous, once pinnate

 veinlets of the pinnl. sometimes forked ; sori small, linear-oblong, 2 to 12 to a 

 pinnl. — Athyrium, Moore. 



Hab. Guatemala. — Perhaps thi§ ehould be joined with the next, but the pinnse and
