Hab. Columbia, Moritz, 408, Fendler, 159. Distinguished by its herbaceous texture 

 and broad lobes, not reaching much more than halfway down to the midrib.

 lower pinnae dwindling down gradually to mere auricles; texture herbaceous, 

 under side naked ; veinlets 8-9 on a side ; sori near the midrib ; invol. prominent, 

 glandular. Hk. Sp. 4. p. 100. 



Hab. Venezuela, Moritz, 409, Fendler, 472. Deeper cut than the last, and nearly 

 naked, with a more prominent and persistent involucre. A . decrescens and cheilanthoides,
