Description Plants with loose, branching system of slender, pale brown rhizomes. Culms very slender, nodding, 15–60 cm, exceeding leaves, scabrid. Leaves: basal sheaths pale brown abaxially, inner band white-hyaline, truncate at summit; ligules broader than long; blades mid to dark green, flat, 15–30 × 0.75–1.5 mm, scabrid. Inflorescences 1.5–2.5 cm × 3–5 mm; proximal bract 5–20 mm; distal bracts scalelike. Spikes 2–4(–5), proximal separate, distal aggregate, globose, 3–5 × 2–4 mm. Pistillate scales white-hyaline with green center, ovate, narrower and shorter than perigynia, apex acuminate. Perigynia 1–6, pale green, often brown or even purplish in age, plump, 2.25–3 × 1.3–1.5 mm, membranous, shiny. Achenes red-brown, oblong-elliptic, 1.5–1.75 × 1 mm, glossy. 2n = 70. [details]
