Description Plants loosely cespitose, often in large clumps; rhizomes slender, long. Culms arching, weak, 20–70 cm. Leaves: sheaths pale brown abaxially, inner band tight, thin, hyaline, truncate at summit; ligules as wide as long; blades green, flat or channeled, 5–20 cm × 0.25–2 mm. Inflorescences nodding, 5–10 cm × 3–4 mm; proximal bracts bristlelike, 3–10 cm, exceeding inflorescences. Spikes 1–3, remote, 2–4 cm apart, containing 1–5 perigynia, ovoid, 4–6 × 3–4 mm. Pistillate scales whitish with green, 3-veined center, ovate, subequal to perigynia, apex acute (mucronate). Perigynia ascending, pale green or brownish in age, finely many-veined, ovate-elliptic, 2.5–3.7 × 1.5–2 mm, subcoriaceous; beak entire or with few small teeth. Achenes brown, elliptic-oblong, 1.75–2 × 1.25(–1.5) mm, glossy. 2n = 60. [details]
