§ 2. Stigmas 3. 
* Terminal spike 
sterile, the rest andro- 
gynous.

approximate, elliptic, 
sessile; fruit ovate, 
compressed, glabrous, 
about as long as the 
ovate acuminate scale. 
Mich. 2. p. 170. 
Stem twelve to eighteen inches high, acutely triquetrous, scabrous along 
the margins, slender. Leaves linear, slightly scabrous on the edges, scarcely 
longer than the stem, a little pubescent near the sheaths. Spikes generally 
four, three larger, approximate, whence the name given by Michaux, the 
fourth smaller, and a little remote, all sessile, or on very short peduncles, 
the base of the upper spike surrounded with male florets. Scales ovate, 
slightly acuminate. Corolla of the female florets ovate, somewhat com- 
pressed, not pointed at first, shorter than the scale, when old quite as long. 
Stigmas three. Seeds triquetrous. 
Nearly allied to C. Ylrescens, from which it appears to differ by its cylin- 
drical or elliptic spikes and glabrous corolla. 
Grows in damp soils. 
Flowers April— May.
