Culms mostly phyllopodic, with dead leaf remains at base, 10–80 cm. Leaf blades 1–4 mm wide, margins revolute, scabrid. Inflorescences: proximal bracts 3–15 cm, equaling or exceeding inflorescences; lateral spikes, at least the proximal, usually with 1–3 staminate flowers at base, 6–22 × 4–8 mm, with 5–20 perigynia; terminal spikes occasionally gynecandrous with 1–8 pistillate flowers, 7–20 × 1–4 mm. Pistillate scales lanceolate, 2.8–7 × 1.1–2 mm, longer, narrower than perigynia, apex acute to acuminate, often awned to 3 mm. Staminate scales oblanceolate to obovate, 4–6 × 1–1.6 mm, apex obtuse to acute. Anthers 1.6–2.5 mm. Perigynia 2.5–3.6 × 1.8–2.5 mm, apex rounded; beak absent or to 0.2 mm. 2n = ca. 60.
