7. Psilogramme refracta (Kunze) Maxon. 



Gymnogramma refracta Kunze; Klotzsch, Linnaea 20: 410. 



1847. 

 Anogramma refracta Fee, Gen. Fil. 184. 1852. 

 Type locality: Sierra Nevada, Colombia {Moritz 359). 

 Distribution: Colombia and Costa Rica, ascending to 2,300 



Illustration: Fee, op. cit. pi. 19. A.f. 2 (^s A. refracta). 



The present species is here determined solely from the original 

 description and the small detailed figures by Fee. Without an 

 examination of the Moritz type specimen it cannot be shown posi- 

 tively that Kuhn erred in referring this form to P. flexuosa, yet 

 from the data at hand this seems almost certain. In any event, 

 the Costa Rican plant mentioned below is not referable to P. 

 flexuosa. Of published species it seems to agree only with the 

 South American P. refracta; and if it is not really of that species 

 it must subsequently be described as new. Its distinctive char- 

 acters are indicated in the key.

One of the smallest species of the genus, and the only North 

 American member of the group in which the veinlets do not extend 

 to emarginate apices of the teeth. It has previously been com- 

 pared with P. hispidula (Klotzsch) Kuhn, which is probably its 

 nearest relative.
