 flowered except at the base, i'-4' long, $"-%" in diameter, 

 the upper sessile or nearly so and erect, the lower slender- 

 stalked; perigynia ovoid, pubescent or glabrous, promi- 

 nently many-ribbed, 4"-s" long, if-2" in diameter, taper- 

 ing gradually into the stout conspicuously 2-toothed beak, 

 the teeth erect or somewhat spreading, 1" long; scales

Culms stout, erect, smooth, or roughish above, 

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

 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"-2i" 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
