Plants cespitose. Culms straight, 10–50 cm, tallest ones 25–50 cm. Leaves of flowering stems usually shorter than culms, 5–20 cm × 1.5–2.9 mm; ligules on distal cauline leaves truncate or rounded. Inflorescences: peduncles of terminal staminate spikes 0.5–8 mm, 0.2–0.5 length of staminate spikes; bracts to 20 cm × 1.1–2.9 mm, 1.5–4 times as long as inflorescences; inner band of sheaths concave or truncate. Spikes: proximal pistillate spikes (1–)2–5, approximate, subsessile or short-pedunculate, globose to elliptic, 8.5–19.9 × 4.1–9.8 mm; terminal staminate spikes pedunculate, 12–21 × 1.3–2.7 mm. Scales: pistillate scales yellowish green, inconspicuous among perigynia, 1.7–2.6 × 0.8–1.2 mm; staminate scales yellowish green, ovate, 2.9–4.4 × 0.8–1.6 mm, apex obtuse or acute to acuminate. Anthers 1.1–2.9 mm. Perigynia reflexed, yellowish green, 3.5–4.8 × 1.1–1.7 mm, apex gradually narrowed; beak 1.4–2.5 mm, forming an angle of 13–48° with body, smooth. Achenes 1.2–1.5 × 1–1.2 mm. 2n = 64.

Densely cespitose, not stoloniferous, the rootstock very short-prolonged, the culms 2-6 dm. high, erect, slender, exceeding the culm-leaves, but mostly exceeded by leaves of sterile shoots, phyllopodic, smooth or very nearly so, obtusely triangular below, acutely triangular above, light-brown and more or less fibrillose at base; leaves 4-6 to a fertile culm, on lower fourth, but not bunched, light-green, the blades erect, flat, usually 0.5-2.5 dm. long, 1.5-3 mm. wide, roughened toward apex, not septate-nodulose, the sheaths conspicuously dull-whitehyaline ventrally, not prolonged upwards at mouth; sterile shoots phyllopodic, conspicuous, the blades averaging longer; staminate spike subsessile to strongly peduncled, 7-18 mm. long, 2-3 mm. wide, occasionally partly pistillate at base, its scales oblong-lanceolate, acute, greenishyellow, with 3-nerved green center; pistillate spikes 3 or 4, the upper 1 or 2 approximate, the next strongly separate and the lowest often very strongly separate, mostly staminate at apex, sessile or the lower exsert-peduncled, oblong, 10-20 mm. long, 7-10 mm. wide, closely 15—35flowered in many rows, the upper perigynia ascending, the middle spreading and the lower obliquely attached and conspicuously deflexed; bracts leaf -like, the lower long-sheathing, the upper short-sheathing, convex at mouth, the lower with erect, the upper with widely spreading blades; scales lanceolate or ovate, acute, greenish-yellow, with 3-nerved green center, not or but very little reddish-tinged, narrower than and about the length of body of perigynium, concealed and inconspicuous at maturity; perigynia 3.5-4.5 mm. long, the body obovoid, 1.75 mm. wide, inflated, triangular-suborbicular in cross-section, the upper part empty, light-green or yellowish-green, or at maturity yellowish, about 10-ribbed, round-tapering at base, sessile, abruptly slenderly beaked, the beak nearly as long as body, straight or the lower bent, smooth or very nearly so, prominently bidentate, the teeth smooth, closely contiguous to one another, whitish at top or in age slightly tawny-tinged; achenes small, obovoid, 1.5 mm. long, 1 mm. wide, triangular with concave sides, blackish, slightly silvery-shining, prominently pitted, very short-apiculate, jointed with the slender, bent, at length deciduous style; stigmas 3, slender, light-reddish, short; anthers 2.5 mm. long.
