Description Plants without conspicuous rhizomes. Culms 20–90 cm, 1.5–3 mm wide basally, 0.9–1.1 mm wide distally. Leaves: sheaths tight, green, fronts hyaline, yellowish and thickened at mouth; ligules to 3 mm, as long as wide; widest leaf blades 2.5–4.5 mm wide, sometimes papillose adaxially. Inflorescences with (3–)5–10 spikes, 1.5–3.5 cm × 8–15 mm; proximal internodes equaling or shorter than proximal spikes; proximal bracts 1–5 cm; spikes with 8–20 ascending or spreading perigynia. Pistillate scales hyaline or brown with green, 3-veined center, ovate, (2.4–)3–4.3 × (1–)1.6–3 mm, body slightly shorter to longer than perigynium and as wide, apex awned to 1.5–3.5(–4) mm. Anthers 2.2–2.5 mm. Perigynia pale green, pale yellow, or pale brown, 9–15-veined abaxially, 3.5–5 × 2.2–3 mm, margins serrulate distally; beak 0.8–1.2 mm, apical teeth 0.4–0.6 mm. Achenes suborbiculate, 1.9–2.5 × 1.5–2 mm. [details]
