 Lonchitis repens L., — Linne, Syst. Nat., vol. 11, p. 689. 



Although this species was quite common near Camp Meno- 

 cal along the Deseado River bottoms, only one specimen was 

 collected. 



The fronds measured 8 to 9 feet in total length, being larger 

 than stated in Hooker and Baker's Synopsis Filicum. The 

 fronds are broadly triangular, 3 to 4 pinnate, with spiny stipe 

 and rachis. 



Not heretofore reported from Nicaragua. 



2. H. hostilis Prcsl. PI. v, Fig. 3. 



Hook., Sp. Fil., vol. 11, p . 69; Hook, and Bak., Syn. Fil., p. 130; Hemsl., Biol. 

 Cent. Am., vol. 111, p. 6j2. 



A specimen which was collected near Camp Menocal is 

 referred to this species. It answers well to the descriptions 

 cited but there is some question as to the distinction between this 

 and the preceding form, as has already been noted by Baker. 1 



Since the material is scant, no attempt is here made to deter- 

 mine the relationship and synonymy of the members of this 

 group of the genus. 



The species is new to the Nicaraguan list.
