Description Plants densely cespitose; rhizome internodes 1.2–2.8 mm thick. Culms yellow-brown to dark brown at base, 2–75 cm. Leaves: sheaths glabrous; blades green, widest blades (2.3–)3–3.9(–5.6) mm wide, smooth abaxially or sparsely antrorsely scaberulous on main veins. Inflorescences (0.12–)0.21–0.91(–0.99) of culm height; peduncles of lateral spikes scaberulous; peduncles of terminal spikes 2.9–71(–103) mm, barely exceeded by to much exceeding lateral spikes; proximal bract sheath loose, abaxially glabrous, sheath front slightly convex, elongated 0.5–1.6 mm beyond apex; ligules 0.8–2.9(–3.7) mm; distal bract slightly shorter than to much exceeding terminal spike. Spikes (2–)3–6, widely separate or distal 2–4 overlapping or rarely all congested; lateral spikes pistillate, with (6–)18–37(–86) perigynia, 5–29 × 3.1–10.2 mm, ratio of spike length (in mm) to flower number = 0.51–0.95; terminal spikes (5–)8–26(–30) × 1–3.3(–4.2) mm. Pistillate scales 2.4–4.7 × 1.4–2.1 mm, margins red-brown to whitish, entire, apex with awn 0.2–2.7 mm or rarely awnless. Staminate scales (2.3–)2.9–4.5 × 1–1.6 mm. Anthers 1.8–3.6 mm. Perigynia spirally imbricate, 17–25-veined, unwrinkled, oblong-ovoid to oblong-obovoid, orbicular or suborbicular in cross section, (2.5–)2.8–3.6(–4.3) × (1.2–)1.3–1.7(–1.8) mm, (1.7–)1.9–2.5(–2.8) times as long as wide, lustrous, base very gradually tapered, apex gradually tapered; beak absent or straight, 0–0.2 mm. Achenes obovoid, 1.8–2.6 × (1–)1.2–1.4 mm, loosely enveloped by perigynia; stipe straight 0.1–0.3(–0.4) mm; beak straight, 0.2–0.4(–0.5) mm. [details]
