 P. diforme, and No. 8 under his P. gracile, but a comparison of 

 the descriptions does not afford much satisfaction. Elliott 

 described eleven species of Paspalum, or thirteen, if we include 

 his Milium paspalodes and Ceresia fluitans. The monograph of 

 Le Conte enumerates eighteen species, of which four or five had 

 not been previously described and m^y be counted new species 

 or varieties. All these are indigenous to the Atlantic States ; 

 the additional ones of the Southwest had not, probably, been 

 collected at the time of this monograph.
