Lomariopsis vcstita Fourn., Sertum Nic, p. 250. 



Climbing on trunks of trees to a height of 2 to 7 feet. The 

 rootstock retains its connection with the soil, and is crowned 

 with a tuft of fronds, the lower and outer of which are sterile. 

 Similar tufts sometimes appear on short branches of the root- 

 stock at some distance from the tip. 



Some of the sterile fronds exceed 2 feet in length, and they 

 are but 3 to 6 inches wide. The pinnae are mostly sessile, 

 and vary somewhat in the depth of the marginal denticula- 

 tions, and in the length of the acuminate apex. One of the 

 fertile fronds is sterile in its lower half. 



Common in the higher woods near Castillo, where the fer- 

 tile fronds were just beginning to appear at the time of collect- 

 ing, and along the Deseado River above Camp Menocal. 



Reported from Chontales by Fournier ^as L. vcstita), and 

 by Hemsley.

Acrostic/ium cylindncum Hook., Sp. Fil., vol. V, p. 246. 



With the habit of growth of A. sorbifolium. The rootstock 

 is 3/g of an inch thick. In the specimen in the collection the 

 scales have all fallen away, leaving irregular tubercles. Only 

 one specimen with both fertile and sterile fronds was found in 

 the woods near Castillo.
