8. Odontosoria gymnogrammoides Christ, Bull. Soc. Bot. Genéve II. 1: 228. 
1909. PLateE 5, 
TYPE Locality: Estrella, province of Cartago, Costa Rica (Cooper). 
Distrisution: Confined to the interior mountain region of Costa Rica, at 1,400 to 
1,800 meters elevation. 
The type collection of this species has not been seen by the writer. Agreeing with 
the description, however, are Costa Rican specimens, collected by the writer and 
cited by Doctor Christ. The species has some resemblance to O. fumarioides of Jamaica 
in cut of leaf and particularly in texture. 
The following specimens are in the U. S. National Herbarium: 
Costa Rica: Estrella, province of Cartago, alt. 1,320 meters, Cooper (J. D. Smith 
6015), the type collection. Without definite locality, Cooper; A. de Zeledon.

British Honduras, ascending to 1,000 meters.

As noted above in the discussion of this genus as here restricted, the present species 
is wrongly placed by Diels with those species of small size and erect determinate 
growth, which properly constitute a separate genus, Sphenomeris. Nor is there 
warrant for using the name divaricata for this plant, since Schlechtendahl’s publica- 
tion of it is antedated two years by that of Blume. 
Odontosoria schlechtendahlii finds its nearest ally in O. guatemalensis and is like that 
species in being wholly unarmed throughout. 
The following specimens are in the U. 8S. National Herbarium:
