THE FERN'S OF NICARAGUA. 213 



2. The following species, similarly reported as new to 

 Nicaragua, are given in Bommer and Christ's list as occurring 

 in Nicaragua (without exact locality). The correction should 

 be made on the page opposite each name. 



Adiantum platyphyllum Swz. (as seemanni), p. 147. 



Adiantum obliquum Willd. (the var. intermedium reported by Bom. et Ch. 



as a species), p. 145. 

 Davallia inequalis Kze., p. 153. 



3. Trichomanes membranaceum L., recorded by mistake 

 on p. 129 as new to the Central American region, is listed by 

 Fournier as Lecanium membranaceum Presl, in Bull. Soc. Bot. 

 Fn, vol xv, p. 144. 



4. The form of Nephrodium conterminum (Willd.) Desv. 

 described on p. 173 as "copiously clothed with white hairs," 

 is probably the same as Aspidium conterminwm var. -pilosulum 

 (Kl. et. Karst.) Bom. et Ch. of Bommer and Christ's list. 



5. The following more exact data may be of interest in 

 connection with the discussion on p. 120.
