LIST OF BALANSA'S FERNS OF PARAGUAY, WITH 

 DESCRIPTIONS OF THE NEAV SPECIES. 



By J. G. Bakee, F.R.S. 



As very little has been known about the Ferns of Paraguay, 

 and the i^lants recently collected there by Balansa have l)een 

 widely distributed amongst the princiiml European herbaria, I 

 send a list of the determinations of those included in the set which 

 I have had the opportunity of studying. The numbers prefixed to 

 the names are those under which the plants were sent out, and the 

 second number in brackets indicates the position of the novelties, 

 according to the sequence followed in our ' Synopsis Filicum.' 

 Excluding of coiu-se the novelties, all the species are known 

 ah-eady either in Brazil or the Argentine territory, except 

 Gymnogramme leptophijlla, which has been collected by Spruce and 

 others in the Andine region but is new to the east side of Tropical 

 America.
