New Ferns from Brazil 



l'y 

 Carl Christensen. 



In working out a critical list of the ferns in the Botanical 

 Museum at Copenhagen, I have found the following species or 

 varieties to be undescribed or not hitherto recorded from Brazil; 

 in a few species of Fée I have altered the name, when the name

 sched.). It is also recorded from Ouro Preto: Serra das Gamarinhas, leg. 

 Schwacke (vide: Christ in Bull. Therb. Boiss. U, 2, 328 (1902)). All the 

 specimens are sterile.
