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 dififi- 

 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. 



12. E. OVATA (Roth), Roem. & Schultes, Syst. ii. 152 (1817). 

 Scirpus ovatus. Roth, Catl., i. 50 (1797)- 



Scirpus capitatus, Walt. Fl. Carol, 70 (1788), not of Willd. 

 Scirpus obtusus, Willd. Enum. Hort. Berol. i. 76 (1809). 

 Eleocharis obtusa, Schultes, Mant. ii. 89 (1824). 

 Eleocharis diaiidra, C. Wright, Bull. Torr. Club, x. loi 

 (1883) appears to belong here rather than to the var. 

 Enzclinanni. 

 Common throughout eastern North America, extending to 

 New Brunswick, Fowler ; Florida and Texas; Lincoln, Neb., H. 

 J. Webber ; Agassiz and Pitt River, B.C., Macoun ; Multnoinali 

 Co., Oregon, Howell, 409 ; San Bernardino, A. Wood (?). 

 Not reported from the Rocky Mountain region. 

 The style of this species is occasionally three-cleft.
