Loosely strongly stoloniferous, the culms phyllopodic, stiff, 

 sharply triangular and usually roughened above, exceeding leaves, 

 brownish at base, 2.5-6 dm. high. Culms developing some short 

 blades the first year, and in the flowering (second) year 2-4 

 erect blades, 2.5-4 mm. wide, fl-at, with revolute_ margins ; terminal 

 spike normally staminate, short-peduncled, 5-15 mm. long; lateral 

 spikes 2-3, pistillate or staminate above, approximate, sessile or 

 short-peduncled, oblong or linear-oblong, 5-15 mm. long, 4-6 mm. 

 wide, the perigynia 8-30, spreading-ascending, closely packed ; 

 bracts sheathless. the lower normally shorter than the inflorescence ; 

 scales ovate or lanceolate, obtuse to acuminate, exceeded by peri- 

 gynia, purplish-black, the midvein usually obsolete ; perigjmia 

 obovoid, plano-convex, not turgid, 3 mm. long, 1.75 mm. wide, 

 stramineous, often dark-tinged, nerveless except for the two 

 marginal ribs, membranaceous, granular, rounded at base, ab- 

 ruptly minutely beaked, the beak straight, 0.25 mm. long; achenes 

 lenticular ; style slender ; stigmas 2.

 culms 4-^ dm. high, rather slender, sharply triangular and very 

 rough on the angles, exceeding leaves, phyllopodic, strongly

 flat with revolute margins, the sheaths olive-tinged ventrally ; 

 terminal spike staminate, slightly clavate, 6-8 mm. long, sessile or 

 short-peduncled ; pistillate spikes mostly two, sessile or nearly 

 so, the lower separate, short-oblong, 7-10 mm. long, 4.5-6 mm. 

 wide, closely 10-25 flowered ; lowest bract shorter than culm, 

 purplish-black at base; scales ovate, obtuse, half width and half 

 length of perigynia, purplish-black, the midvein obsolete or nearly 

 so ; perigynia ascending or spreading, ovoid, mostly convex- 

 concave, 3.75 mm. long. 1.75 mm. wide, more or less turgid, dull 

 green below, purplish mottled above, sub-membranaceous, nerve- 

 less, granular, prominently sparingly serrulate above, rounded and 

 substipitate at base, tapering above, prominently short-beaked, the 

 beak black, entire, the middle -ones often excurved; achenes 

 lenticular; style slender, jointed with achene ; stigmas 2.

Rootstocks thick, the culms 5-9 dm. high, strongly aphyllo- 

 podic, narrowly wing-angled and very serrulate on the angles, 

 strongly reddish purple at base. Leaves 3-5 to a culm, clustered 

 well above the base, the blades flat, 4-5 mm. wide, very long 

 and scabrous, the sheaths strongly hispidulous and often red- 

 tinged ; terminal spike staminate, short-peduncled, 18-25 mm. 

 long; pistillate spikes 3 or 4, erect, sessile or short peduncled. 

 approximate or lower separate, oblong or linear_-cylindric, 1-2 

 cm. long, 3-4 mm. wide, closely flowered with 15-40 appressed 

 perig>-nia; lowest bract shorter than culm, dark auricled; scales 

 oblong-ovate, acutish or obtusish, half width but nearly length of 

 perigynia, blackish throughout or rarely with lighter midvein ; 

 perigynia obovate, much flattened, 2.5 mm. long, 1.5 mm. wide, 

 green, very obscurely nerved dorsally. round tapering and sub- 

 stipitate at base, abruptly rounded and minutely beaked at apex, 

 the beak 0.25 mm. long, black, entire ; achenes lenticular ; style
