Common on the steep, rocky, wooded banks of the San 

 Juan River, and rare in deep woods near Moyogalpa on Ome- 

 tepe. The latter specimens are smaller. The specimens are 

 typical and in fine fruit. Some of the sterile fronds seem to 

 be proliferous. Several specimens from the banks of the Los 

 Sabalos River resemble those from Ometepe, but the fertile 

 pinna; are shorter, blunter, and wider, and the margins of the 

 sterile fronds are scarcely repand, being almost entire. 



Reported from Chontales (as G. irregularis) by Fournier, 

 and from Granada and Chontales by Hemsley.
