16 POLYPODIUM HEMIONITIDEUM. 



Fronds glabrous, simple, broadly lanceolate in form, undula- 

 ted, unusually membranous, attenuated at the base.

 to Mr. Sim, of Foot's Cray; Mr. Henderson, of Wentworth; 

 Dr. Hooker, of the Royal Gardens, Kew; Mr. Norman, of 

 Hull; and Messrs. Booth, of Hamburg.
