Spicis distinctis ; staminifera unica ovato-oblonga parvi-bracte- 

 ata cum squama oblonga obtusa margine fusca; pistilliferis biriis 

 ovato-cylindraceis superne substaminiferis tristigmaticis peduncu- 

 latis sublaxifloris, inferiore longo-pedunculatis basi vaginatis ; 

 fructibus obovatis subrotundis obtusis nervosis perbrevi-rostratis 

 et retrocurvis, squamam late-ovatam acutam vel obtusam et brevi- 

 mucronata superantibus. 



Culm eight to sixteen inches high, erect, leafy towards the 

 base, glabrous, slightly scabrous above ; leaves shorter below, 

 linear-lanceolate, flat, smooth, pale green ; staminate spike ob- 

 long, large, with an oblong obtuse scale tawny on the margin ; 

 pistillate spikes two, sometimes one, oblong, round, rather loose 

 flowered, sometimes staminate at the apex, upper short-peduncu- 

 late, lower quite long-pedunculate, and both with leafy bracts 

 sheathing at the base ; fruit rather loose, obovate, obtuse, nerved, 

 with a very short beak recurved at apex, and orifice closed ; pis- 

 tillate scale ovate, broad, acute, or short mucronate, reddish on 

 the edge and green on the heel ; pale green. 



This Carex has a remote resemblance to 0. panicea, and C. 

 binervis ; differs in several particulars, as well as from C. poly- 

 morpha. Found by Dr. S. B. Mead at Augusta, 111.
