I2 8 NATURAL HISTORY BULLETIN. 



and with the descriptions and figures cited, leaves but little 

 doubt of the correctness of the determination. 



Compared with Cuban specimens, and with the figures, the 

 specimens are broader, and more nearly deltoid, but the pinnae, 

 though recurved, agree in the mode of division and the 

 character of the segments. 



Hooker (in Sp. Fil., vol. i, p. 107) says: "The fronds are 

 not only variable in general form and circumscription, but also 

 in the direction of the primary divisions, sometimes being 

 curved downwards." 



Most of our specimens have the lower and middle pinnae 

 recurved. 



The species is reported from Chontales, Nicaragua, by 

 Hemsley and Fournier, and from Realejo by Hooker as JV. 

 -protrusum. 



Rather common near Camp Menocal, creeping along the 

 trunks of small trees.

Our specimens are small, the fronds scarcely exceeding 

 two inches in length, and the stipe in most of them is less 

 than an inch long. The fronds are broader and somewhat 

 less ciliate than represented in Hooker and Greville's figure. 



This species has not heretofore been reported from Nica- 

 ragua. Not rare, creeping on the trunks of small trees near 

 Camp Menocal.
