Description Perennial herbs with short, woody, stiff rhizomes. Culms central, loosely turfed, 2.5–11 cm tall, trigonous, with brown fibrous sheaths at the base. Leaves much longer than culms, blades 1.5–3.5 mm wide, flat, leathery, scabrous on the upper part and margins. Lowermost bract leaf-like, longer than the inflorescence, base with a 1–2 mm long sheath or sheathless; other bracts setaceous, shorter than the inflorescence, sheathless. Spikes 3 or 4, aggregated; terminal spike staminate, narrowly linear-cylindrical, 6–20 mm long, 1–1.5 mm wide, base with 1–3 mm long peduncles; lateral spikes pistillate, cylindrical, 4–13 mm long, 2.5–3 mm wide, loosely 9–14-flowered, with peduncles slightly exserted from sheaths. Staminate glumes broadly ovate, pale yellow-brown, ca. 1.5 mm long, apex obtuse, with 3-veined yellow costa. Pistillate glumes ovate, pale yellow, 1–1.2 mm long, apex acuminate, with 3-veined yellow costa. Utricles yellow-green, narrowly fusiform, obtusely trigonous, 2.5–3 mm long, longer than pistillate glumes, membranous, obliquely patent, distinctly thinly veined, sparsely pubescent, base gradually cuneate, short-stipitate, apex gradually contracted into a ca. 0.5 mm long beak, orifice 2-lobed with minute teeth. Nutlets tightly enveloped, brown, narrowly ovoid, trigonous, 1.5–1.9 mm long, with 3 sides slightly concave above and below, base with a ca. 0.2 mm long stipe, apex contracted into a 0.2–0.4 mm long cylindrical beak, truncate and shallowly concave at top; style base slightly thickened; stigmas 3.
