Description Plants densely cespitose; rhizomes ascending, reddish brown, 0–10 mm, stout. Culms 3–12 cm, strongly scabrous distally; bases (remnants of old leaves) weakly fibrous. Leaf blades green, usually exceeding stems, 0.8–1.5(–2.6) mm wide, herbaceous, glabrous abaxially, glabrous or slightly scabrous adaxially. Inflorescences with both staminate and pistillate spikes; peduncles of basal spikes erect, elongate, slender; peduncles of staminate spikes 4–6.9 mm; proximal nonbasal bracts leaflike, exceeding inflorescences. Spikes: proximal pistillate spikes 2–3 (basal spikes 1); cauline spikes overlapping or somewhat separated, with 1–3 perigynia; staminate spikes 4.8–5.7(–8) × 0.7–1.5 mm. Scales: pistillate scales pale reddish brown with white margins, ovate, 2.9–3.6 × 1.4–1.8 mm, equaling or shorter than perigynia, apex acute to acuminate; staminate scales ovate to lanceolate, 3.9–4.8 × 1.2–1.8 mm, apex acute to acuminate. Anthers 1.2–2.1 mm. Perigynia green to yellowish brown, veinless, ellipsoid to ovoid, 3.3–4.4 × 1.4–1.6 mm; beak slightly bent, green to yellowish brown, often reddish brown at apex, 0.7–1.6 mm, smooth or weakly ciliate-serrulate, apical teeth 0.2–0.4 mm. Stigmas 3. Achenes brown, obovoid, obtusely trigonous in cross section, 1.9–2.1 × 1.4–1.6 mm. [details]
