Southern Texas. Apparently collected only by G. C. Nealley 

 at Brownsville in 1 889. Occurs also in the West Indies. Rick-

This, as indicated above, has been considered a variety of C. 

 aliata Sw., but according to our conception of that species, based 

 upon the descriptions of its author, this must be quite different. 

 In the original place of publication of C. ciliata* Swartz does 

 not give a very extended description, and if this were the only 

 source from which to draw the result would be rather dubious, 

 but in his subsequent work on the flora of the West Indies t a 

 much longer and more definite description is given, with a refer- 

 ence to the first place of publication. In this latter work the 

 sheaths are said to be villous at the throat, and the third scale 

 with an awn twice its length and the hairs as long as the scale. 

 In C. Tcxana, as will be noted above, the ligule is a mere ciliolate 

 scarious ring which could hardly be called villous under any con- 

 ception of that term, and the third scale has the awn much shorter 

 than itself and the hairs longer than the scale. What the C c0r 

 ata of Swartz is we do not know, no material that could be prop
