Description Perennial herbs. Rhizomes woody, obliquely ascending. Culms lateral, 45–60 cm tall, trigonous, smooth, base with short leaves and brown fibrous sheaths. Leaves longer than culms, blades flat, leathery, 4.5–9 mm wide, scabrous on upper surfaces and margins. Bracts leaf-like or shortly leaf-like, base with 1–2.5 cm long sheath. Spikes 6; terminal spike staminate, cylindrical, 5–7.5 cm long, 4–5 mm wide, base with 8–20 mm long peduncles; lateral spikes pistillate, cylindrical, 2.5–4.5 cm long, 3–3.5 mm wide, densely flowered, with peduncles exserted from or enclosed in sheaths. Staminate glumes elliptic-lanceolate or oblanceolate, pale brown, 7–7.5 mm long, apex acuminate, with 3-veined yellow-brown costa. Pistillate glumes ovate-elliptic or obovate, pale yellow, 2.5–3 mm long, apex acuminate and mucronate, or acute, with 3-veined yellow-brown costa. Utricles yellow-green, narrowly ellipsoid-ovoid, obtusely trigonous, 4–4.5 mm long, longer than pistillate glumes, membranous, obliquely patent, distinctly thinly veined, nearly glabrous, base gradually cuneate, short-stipitate, apex gradually contracted into a ca. 1 mm long beak, orifice 2-lobed with short teeth. Nutlets tightly enveloped, brown, ovoid, trigonous, 2.5–3 mm long, with 3 sides slightly concave below, base short-stipitate, apex contracted into a ca. 0.5 mm long cylindrical beak; style base slightly thickened; stigmas 3.
