Professor Raddi, in his Synopsis of the Ferns of Brazil, 
mentions the Grammitis serrulata as an inhabitant of that 
country ; but if I may judge from the plant which he has been 
kind enough to send me under that name, it is the same with 
the G. myosuroidesy likewise a native of Brazil as well as of 
the West Indies. 
This last differs from our plant in the pinnatifid, not den- 
tate frond, and is certainly very closely allied to it, if it be not 
in reality a variety.
