THE FERNS OF NICARAGUA. 20J 



Addendum. 



Since the first forms of this paper were printed, a number 

 of additional reference-works have been received. While 

 these were not consulted for the earlier determinations as they 

 appear in the paper, they were so employed in the latter part 

 of the work, and in order that the references to the Xicara- 

 guan species discussed in these works mav be complete as far 

 as possible, the following additional list of references, which 

 should have appeared under the species listed, is here appended. 

 For convenience the genera and species are alphabetically 

 arranged. The ferns listed in Bommer and Christ's paper are 

 from Costa Rica, unless otherwise specified.
