Description Plants with short-creeping rhizomes to 6 cm. Culms 20–70 cm, 1.2–1.8 mm wide basally, 0.4–0.7 mm wide distally. Leaves: sheaths tight, green, fronts hyaline; ligules less than 2 mm, wider than long; widest leaf blades 1.5–2.2 mm wide. Inflorescences with 3–5 spikes, 2.5–5 cm × 4–6 mm; proximal internodes more than 2 times as long as proximal spikes; proximal bracts to 5 cm; spikes with 4–9 ascending to spreading perigynia. Pistillate scales hyaline with green midvein, ovate, 1.5–2.3 × 1–1.5 mm, body 1/2–3/4 length of perigynium, apex acute to awned. Anthers 1 mm. Perigynia green, usually 7–11-veined abaxially, 3.2–4.2 × 0.7–1.3 mm, base of body spongy, thickened, longitudinally striate adaxially, spongy region 1–1.5 mm, margins serrulate distally; beak 0.7–1 mm, apical teeth 0.2–0.4 mm. Stigmas straight or slightly twisted or coiled, 0.03–0.06 mm wide. Achenes elliptic, 1.8–2.3 × 0.8–1 mm. 2n = 58. [details]
