The limits of this species, P. podophylla, and P. kunzeana are obscure, and the 
synonymy of the three species is confused.

Pteris nemoralis, Willd. ; Liebm. Mexicos Bregner, p. 74? 
A very widely dispersed fern in the tropical zone, and recorded by Fournier from 
many localities in Mexico and CunTraL America; but there are no specimens bearing 
this name in the Kew Herbarium from within our limits, though Litobrochia galeottii 
is cited in the ‘ Synopsis Filicum’ as a probable synonym of P. biaurita. It appears, 
however, that Fournier’s idea of this species differed from Hooker and Baker's, as 
several of the collectors’ numbers referred by him to P. biaurita are named P. quadri- 
aurita in the Kew Herbarium, and P. edentula, Kunze, is indicated in the ‘Synopsis’ 
(p. 159, sub P. pungenti) as normal P. quadriaurita.
