Scleria microcarpa var. foliosa, Clarke in Urban, Symb. 

 Ant. II : 149. 1900. 



Damp field near Port Antonio (Fredholm 3298). Not otherwise 

 known from Jamaica. The var foliosa, Clarke, is said to differ 

 from the species in the less ciliate margin of the disk, but this 

 appears to be a very variable character, and I do not regard it as 

 important in this plant. Widely distributed in Tropical Ame- 

 rica.
