The extensive range which the above-cited localities indicate 

 would appear to show that this species may be more common 

 than we now know it to be. Dark glumed forms are with diffi- 

 culty separable from E. ovata. Dr. Torrey reports it from 

 Georgia, but there are now no specimens of it from that state in 

 his herbarium, nor have I been able to trace his var. /? (Ann. 

 Lye. iii. 305) ; the plant referred by me to this (in Bull. Torr. 

 Club, xi. 87,) is E. albida, which long headed forms of the 

 present species closely simulate.
