Description Plants densely to loosely cespitose, forming tufts up to one m in diam. Proximal sheaths scaly, bladeless, red to dark purple, smooth to scabrous on the prominent nerves, veins sometimes persisting and ladder-fibrillose. Distal sheaths with translucent faces, often red-streaked, apices concave; ligules obtuse, mostly longer than wide, margins scabrous; distal sheaths bearing blades.Leaves in numerous sterile rosettes, 4-10 on proximal 1/4 of stem, some blades taller than fertile stems, blades 6-42 mm long, 1.7-3. 8 mm wide, V-shaped in cross-section, often folded, green not blue-green, 5-10 prominent veins, scabrous adaxially, blade margins scabrous, tips filiform- triangular, densely scabrous, apex blunt or truncate, bristly (20 X), Stems (culms) 9.5- 35 cm tall, triangular, scabrous. Inflorescences with 1-3 basal spikes 7-11 mm long, on erect filiform scabrous peduncles 1-7.5 cm long, 0,3- 0.4 mm wide, the basal spikes with 2-5 perigynia, mostly pistillate, occasionally androgynous with 2-3 terminal staminate scales; non-basal portion of the inflorescences on elongate stems comprised of 1-4 spikes, the spikes 13-38 mm long, overtopped by foliage; lowest non-basal inflorescence bract often emarginate and purple at base, blade green, leafy, 8- 45 mm long, often shorter than inflorescence; lowest non-basal lateral spikes pistillate, each with 1-5 perigynia, sessile or on peduncles to 5 mm long; distal spike staminate, 12-21 mrn long, 2. 0-3.0 mm wide, 8-17 flowered; stamens 3 per scale, filaments white, anthers yellow, linear, 2. 7^.2 mm long, apical appendage 0.1 mm long, bristly (20x). Staminate scales 4.8- 7.1 mm long, dark purple, sometimes scabrous or sparsely pubescent, with prominent or keeled pale midveins, and 2-15 usually inconspicuous fine parallel lateral veins, apex acute, occasionally rnucronate, mucro to 0.3 mm, often bristly (20x). Pistillate scales ovate to broadly ovate, clasping at base, 3.2-4-.9 mm long, 2. 8^.0 mm wide, glabrous, scabrous, or sparsely pubescent, green central band with (l-)3 strong midveins, the midveins often keeled and scabrous, the broad dark purple lateral bands with 6-12 inconspicuous fine parallel veins, distal margins entire to sparsely ciliate, apex acute, or emarginate and mucronate, the mucro to 0.7 mm and scabrous or ciliate. Perigyeia obovate, pubescent, 3. 4-4.9 mm long, 1.4— 2.1 mm wide; stipe fleshy, oily, turgid and pale when fresh then shriveling, 0.9-1.9 mm long; body plump, rounded-trigonous, usually with 10-16 prominent veins when mature; beak distinct, slightly flattened, erect or slightly incurved, scabrous and pubescent, measured from inflection point 0. 5-0.9 mm long, including teeth 0. 1-0.4 mm long. Acheees obovoid, rounded-trigonous, papillose (20 X), brown, 2.0-2.5 mm long, 1.4— 2.0 mm wide. [details]
