Stem twelve to eighteen inches high, slender, acutely triquetrous, glabrous. 

 Leaves linear, glabrous, shorter than the stem, scabrous along the margin, 

 sheathing at base. Spikes lateral and terminal, the lateral commonly two, 

 on long, slender, pendulous peduncles, the lowest frequently bearing only 

 sterile florets. Bracteal leaves slifrhtlv frinfrpfl. Innapr '

Glumes of all the florets ovate, carinate, slightly acuminate, glabrous, ferru- 

 ginous. Stamens three. Stigmas three. Nut globular, roughened with 

 elevated points and transverse irregular lines, mucronate at the summit. 



I have a variety from Florida in which the stem appears more rigid, and 

 the nut not so conspicuously roughened. 



Grows in damp pastures and pine barrens. 



Flowers May; probably through the whole summer.
