Culms stout, erect, smooth, or roughish above, 

 sharp-angled, 2-5 tall. Leaves elongated, 2i"-6" 

 wide, more or less scabrous, often pubescent beneath 

 and on the sheaths; bracts similar, the lower often 

 overtopping the culm ; staminate spikes as in the pre- 

 ceding species; pistillate spikes 3-5, remote, cylindric, 

 sessile or the lower short-stalked, loosely flowered 

 at the base, dense above, ii'-4' long, sometimes 8" 

 in diameter ; perigynia ascending, lanceolate or ovoid- 

 lanceolate, glabrous, conspicuously many-ribbed, 4"- 

 6" long, gradually tapering into the conspicuously 

 2-toothed beak, the teeth widely spreading, i"-2" 

 long; scales oblong-lanceolate, strongly rough-awned, 

 thin-margined, one-half to two-thirds as long as the 

 perigynia ; stigmas 3.

Rootstocks extensively creeping, culms rather slen- 

 der, erect, nearly smooth, 6'-2 tall. Leaves flat, pubes- 

 cent, especially on the sheaths, rough, i"-2$" wide, the 

 basal ones much elongated, often exceeding the culm, 

 the upper and the similar bracts shorter ; staminate 

 spikes 2 or 3, stalked, their scales ciliate; pistillate 

 spikes 2 or 3, widely separate, erect, oblong-cylindric, 

 7"-i8" long, 3"-4" in diameter, rather loosely lo-many- 

 flowered ; perigynia oblong-ovoid, green, ascending, 

 densely pubescent, ii" in diameter, 2i"-4" long, few- 

 ribbed, tapering into a stout prominently 2-toothed 

 beak, the teeth often as long as the beak; scales mem- 

 branous, lanceolate, aristate, 3-nerved, somewhat
