Description Plants cespitose or not, short-rhizomatous. Culms solitary or not, erect, (15–)30–80(–140) cm. Leaves 6–12; basal sheaths purplish red; sheath of distal leaf 0–1(–2.5) cm; ligules rounded, 1–8 mm; blades 8–27 cm × 3.5–8 mm. Inflorescences 2–15 cm; peduncles of proximal pistillate spikes 0.3–1.5 cm, basal 2 peduncles 0.2–2.1 cm apart; of terminal spike 0.5–4 cm; bracts leafy, sheathless, blades 6–21 × 2–6 mm. Spikes: proximal pistillate spikes 1–4, often closely aggregated and difficult to distinguish, 1–12-flowered, ovoid to obovoid, 1–2.7 × 1–2.8 cm; terminal staminate spike 1, 1–5 cm × 1–3 mm.
