113. Dryopteris illicita Christ, Bull. See. bot. Genève II. 1: 225. 1909. 



Type from Costa Rica, La Palma, Wercklé (not seen). 



To this species I refer specimens from Candelaria, Costa Rica, A. et C. Brade 

 nr. 410 (R). It is a very large species remarkably resembling a glabrous form of 

 0. patens, but the venation and the decrescent lamina show that it is a member 

 of the subgenus Lastrea. The thick, quadrangular, stramineous rachis and the 

 costæ are sparsely pubescent above, otherwise the leaf is quite glabrous and 

 eglandulose, but the costæ and costulæ bear beneath some thin, light-brown scales. 

 Segments close, subfalcate, acute, the basal ones both prolonged and parallel to 

 rachis as in D. patens. Veins about 10 to a side. Sori supramedial with sub- 

 persistent, glabrous indusia.
