nervosis in margine senulatis ore bidendatis, squamae ovatse acutae 

 subsequalibus. 



Culm three to six inches high, smooth leafy ; leaves sheathing 

 towards the base, narrow, longer than the culm ; spikelets androgy- 

 nous, staminate above, several, aggregated into a roundish head ;

Spicis distinctis, staminifera solitaria, pistilliferis subbinis tristig- 

 maticis, sessilibus approximatis subrotundis parvifloris ; fructibus ob- 

 ovatis brevirostratis subtriqaetris-globosis ore bilobis, sqij^mse ovatse 

 acutse vix sequantibus. 



Culm six to eight inches high, triquetrous, scabrous, stiff; leaves 

 sheathing, longer than the culm, but lower ones abbreviated, chan- 

 neled, nearly flat, and scabrous on the edge ; one staminate spike 

 oblong and cylindric, with oblong and acutish scales brown, and white 

 on the edge ; stigmas three ; pistillate spikes one to three , sessile, 

 nearly ovate-globose, few flowered, with an ovate and cuspidate 

 bract and sometimes leafy under the lowest spike ; fruit obovate, 

 globose, slightly triquetrous, short-rostrate, orifice two-lobed, scale 

 ovate, acutish, brown, white on the edge, a little shorter than the 

 fruit ; color a bright green. 



This species Vv^as found originally at the Caspian Sea. It was 

 found also by Dr. Richardson at Lake Winipeg. According to 

 Willd., the spkes have three or six fruit, sometimes two or three. 

 Its resemblance to C. supina, described in Vol. XXVI of this Jour- 

 nal, is remarked by Willd., and Sclik. Both the plants are unlike 

 others in our country, and so near these descriptions, that there can 

 be no doubt of their identity.
