Description Loosely cespitose from hard, ascendent, branched rhizomes, the rhizomes ca. (0.3–) 0.5–2 (–4) cm long between shoots; fertile culms (3–) 8–87 cm long, at maturity erect, decumbent, or prostrate, usually much longer than the leaves, wiry and flexuous or not so, trigonous, 0.2–0.65 (–0.85) mm wide ca. 1 cm below the inflorescence, the angles acute, prominent, scabrous to ciliate; bladeless basal sheaths yellowish brown to red or dark purple, soon ruptured and fibrillous. Leaves 5–10, mostly on the lower 1/3 to 1/8 of the culms, occasionally one present a few centimeters below the inflorescence; blades 3.5–25 cm long, 0.8–3.8 mm wide, flat to conduplicate, pubescent basally or almost glabrous, scabrous to ciliate on margins and occasionally on the main veins; leaf sheaths 1–15 cm long, tight, dorsally pubescent or glabrous, green, the inner band membranaceous, pubescent to nearly glabrous, stramineous to pale brown, sometimes red- or brown-dotted, hyaline and easily ruptured, concave to truncate, ciliate at apex; ligules rounded to acute, 0.6–3.7 (–4.6) mm long, the free portion ciliate, 0.1–0.3 (–0.4) mm wide, whitish to brownish. Inflorescences (1–) 2.5–6.1 cm long, spikes (1–) 2–4, overlapping or the lowermost separated up to 3 cm, single at nodes, sessile or the lowermost sometimes on a filiform peduncle up to 12 mm long; a single pistillate spike is occasionally present on a filiform (0.2 mm wide) ciliate basal culm; the lowest bracts ± scalelike to filiform-triangular to foliaceous, scabrous distally, 0.25–8.5 cm long, 0.1–1.6 mm wide, shorter or longer than the inflorescence, sheathless or with a sheath 1–5 mm long, the upper bracts reduced, scalelike and sometimes awned; terminal spike gynaeandrous, (6–) 8–30 mm long, with an ovoid to cylindrical distal pistillate portion 4.5–16 mm long and 3.5–6 mm wide, 6–45-flowered, the staminate portion 2–22 mm long, 1.5–2.5 mm wide, 3–45-flowered, cylindric-obconic to turbinate; lateral spikes pistillate or gynaeandrous, 5–15 mm long, 3.5–6 mm wide, ovoid to cylindrical, with 6 to 35 (–50) perigynia. Pistillate scales 1.7–3.4 mm long, 1.1–2 (–2.2) mm wide, 1.2–2.2 times as long as wide, ovate to ovate-lanceolate, obtuse to acute, rarely with a minute mucro to 0.1 mm long, glabrous (rarely minutely scabrous), stramineous to brown or purple with a green or stramineous 3-nerved center and usually with narrow hyaline margins and apex; staminate scales 2.7–4.8 mm long, 1.2–2.3 mm wide, 1.7–3.2 times as long as wide, lanceolate to obovate, acute, stramineous to brown or purple with a green or stramineous 3-nerved center and narrow hyaline margins, glabrous or sparsely pubescent. Perigynia 2.2–4.1 (–4.6) mm long, 1.4–1.75 mm wide, widest at 1.4–2.3 mm below apex, ascending, trigonous to flattened-triangular with elliptic to rhombic-ovate sides, glabrous, firm-membranous, scarcely inflated, green to pale brown, sometimes red-dotted, faintly 6–16-nerved or with some nerves prominent, conically tapered to a truncate, entire, minutely erose, or emarginate apex; beak absent. Achenes 1.6–2.6 mm long, 1.1–1.5 mm wide, trigonous, ovoid, ellipsoid, or obovoid, brown with paler, yellowish angles, minutely puncticulate, pedicellate and apiculate. Style straight, withering; stigmas 3. Anthers 3, 1.4–2.3 mm long. [details]
