This well-marked species was rather common near Camp 

 Menocal, climbing on the trunks of trees by its slender, black 

 rootstocks. 



Some of the fronds have a distinct lobe on the lower side 

 of the lowest pinna at the base. This is somewhat developed 

 in specimens from Guadaloupe and Surinam with which com- 

 parison was made, but is not so prominent in them as in the 

 frond from Nicaragua figured on plate 11. The involucres are 

 very slender, prominently exserted, and often deflexed. 



The species has not been heretofore reported from the 

 Central American region.

Some of the fronds in the collection are almost identical 

 with those figured by Hooker and Greville, though smaller, 

 while others are shorter, broader, and more divided. In all 

 other details, including texture and the broad undivided mouth 

 of the involucre, they are the same. The stipes vary from 

 }i to 1 inch, and none of the fronds (without stipe) exceed 2 

 inches in length. 



Growing with T. kraasii near Castillo. Not common. 



The only record of its occurrence in Nicaragua is in Four- 

 nier's Sertum JYicaragucnsc, where it is listed without locality.
