Numerous well-fruited specimens were found on a prostrate, 

 rotten log near the La Juana River. The fronds were so 

 closely crowded together that they formed a dense, moss-like 

 covering on the log. Very few of the fronds reach a length 

 of 1 ^2 inches. Not heretofore reported from Nicaragua.

Very common near the foot of the volcano Ometepe, being 

 gregarious on otherwise barren surfaces. Also on sides of 

 bluffs of volcanic rock. The pinnules, segments, etc., are 

 mostly very obtuse, being often dilated toward the apex, this
