 (1846). Polypodium semicordatum Sw. Prodr. 132 (1788).

Cystopteris Bernh. 



C. fragilis (L.) Bernh. in Schrad. Neues Jour. Bot. I. pt. 

 2, 26, 49, t. 2, f. 9 (1806). Polypodium fragile L. Sp. PI. 

 1091 (1753). C. fragilis Bernh. I.e.; Rob. (1), 109.— 

 Charles Isl. : ace. to Wolf. Robinson 1. c. has already ex- 

 pressed some doubt about the identity of the Galapagos Island 

 specimen. As this was one of the islands most thoroughly 

 explored by our party, and as this species does not appear in 

 the collection, it seems very likely that Wolf was wrong in 

 his determination. Widely distributed.
