numerous specimens of Scleria. Michaux does not notice the 

 fruit, and I did not particularly examine his specimens. He 

 states that it grows in the woods of Carolina. Elliott has a 

 variety of this species, which he calls strigosa, and which 

 differs from the ordinary form in being " less hairy, excepting 

 along the angles of the culm and margin and midrib of the 

 leaves ; its spikes also are larger and more numerous ; its 

 glumes fringed, of a light chestnut colour ; and the nut rather 

 roughened by distinct tubercles than by transverse lines." It 

 was collected by Dr. Baldwin on the confines of Georgia and 

 Florida ; and Mr. Elliott thinks it may be a distinct species.
