 t 



roughened; sheaths longer than the stem, closed, glabrous; stlpulrt 

 membranous, ('alya- 2-valved, unequal, somewhat lanceolate, mem- 

 branous, expanding, persistent Florets 1—3 (4 Pursh,) caducous. 

 Corolla 2-valved ; the exterior valve lanceolate, rather obtuse, not 

 keeled, strongly- nerved; the interior impressed. 



My specimens were not perfect. All the spikelets which had not 

 been exposed, were triflorous; but the caljx was still remarkable for 

 want of connection with the florets. 



Fr m specimens sent from Columbia, by Mr. Herbemont.
