Description Plants not cespitose; rhizome internodes 2–3.4 mm thick. Culms strongly purple-red or yellow-brown tinged with purple-red to 4.8–10.4 cm high at base, 20–60(–68) cm. Leaves: sheaths glabrous; blades green, widest blades 2.4–5.1(–6.7) mm wide, smooth abaxially. Inflorescences 0.21–0.57(–0.95) of culm height; peduncles of lateral spikes scaberulous; peduncles of terminal spikes (2.5–)18–121 mm, usually much exceeding lateral spikes; proximal bract with sheaths tight, abaxially glabrous, sheath front apex concave, elongated 0.2–2.5 mm; ligules 0.2–4.3 mm; distal bract shorter than terminal spike. Spikes 1–3, widely separate; lateral spikes pistillate or androgynous, with 3–13(–22) perigynia, (19–)13–39 × 3.9–8.3 mm, ratio of spike length (in mm) to flower number = 1.7–3.4; terminal spikes (16–)20–43 × (2.8–)3.3–4.5(–5.4) mm. Pistillate scales 3.3–11.1(–17.9) × 2–2.8 mm, margins entire, whitish, apex with awn 0.2–8.3(–13.7) mm. Staminate scales 4.2–5.7 × 1.2–1.6 mm. Anthers 2.4–4.4 mm. Perigynia spirally imbricate, 42–65-veined, unwrinkled, obovoid or narrowly obovoid, obtusely triangular in cross section, 3.4–5.1 × 1.5–2 mm, 1.8–2.5(–3.2) times as long as wide, dull, base gradually tapered, apex gradually or abruptly tapered to subacute; beak absent or excurved, 0–0.4(–1.2) mm. Achenes obovoid, 2.6–3.4 × 1.4–1.8 mm, tightly enveloped by perigynia; stipe 0.1–0.3(–0.6) mm, bent 30–60°; beak bent 35–80°, 0.25–0.45 mm. [details]
