New Ferns from Brazil 



by 



Carl Christensen. 



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

 Museum at Copenhagen, I have found the following species oi- 

 varieties to be undescribed or not hitherto recorded from Brazil;

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

 Schwacke (vide: Christ in Bull. I'herb. Boiss. II, 2, 328 (1902)). All the 

 specimens are sterile.
