Cespitose, growing in beds (not in dense tussocks), freely long- 

 stoloniferous, the culms aphyllopodic, 3.5-9 dm. high, erect, 

 slender, sharply triangular, 3.5 mm. wide at base, 1.5 mm. above, 

 very rough above, purplish tinged at base, exceeding leaves, the 

 basal sheaths hispidulous, strongly filamentose. Lea\'es with 

 well-developed blades three or four to a fertile culm, the blades at 

 first glaucous-green or in age light green, revolute margined, 

 fiat to base, 2.5-3.5 mm- wide, mostly 2-4 dm. long, the margins 

 very rough, the sheaths strongly yellowish-brown tinged ventrally. 

 Terminal spike staminate, strongly peduncled, linear, 2-3 cm. 

 long, 3 mm. wide, the scales oblong-obovate, obtuse, purplish- 

 black with lighter center and narrowly hyaline margins. Lateral 

 spikes mostly three, pistillate, approximate and sessile or nearly 

 so-, or the lowest often remote and slender long-peduncled, linear, 

 4-5 mm. wide, 1.5-3 cm. long, with very many ascending peri- 

 gynia, closely (or at base more loosely) packed in several ranks. 

 Lowest bract leaflet-like, about length of culm, sheathless; the 

 upper much reduced. Scales lanceolate or oblong-lanceolate, 

 obtuse or acute, narrower and from slightly shorter to slightly 

 longer than perigynia, purplish black or in age deep reddish 

 brown with lighter center. Perigynia plano-convex, ovate, 

 closely enveloping achene, light green, granular-roughened, 

 puncticulate, reddish dotted, obscurely few-nerved, 2.25 mm. 

 long, 1.5 mm. wide, two-edged, not serrulate, rounded and sessile 

 at base, abruptly very minutely beaked, the orifice entire. Achenes 

 lenticular, light brown, oblong-obovate, 1.75 mm. long, 1.25 mm. 

 wide, minutely apiculate, the short slender style tardily deciduous; 

 stigmas two.
