Description Rhizome short. Culms tufted, 25-50 cm tall, slender, trigonous, slightly scabrid. Basal sheaths bladeless or with short blades, usually split into fibers. Leaves longer or shorter than culm, blades 1.5-2(-3) mm wide, flat. Basal involucral bract leafy, rarely shortly leaflike, longer than subtending spike, sheathed, sheath 1-2.2(-3) cm. Spikes (3 or)4 or 5; terminal spike male, linear-cylindric, 15-60 × 2-3 mm, with exserted peduncle 0.8-5 cm; lateral spikes female, cylindric, 1-3.5 cm, 2-3 mm thick, rather densely or loosely flowered, lower ones pedunculate, upper ones subsessile. Female glumes pale, obovate or oblong, 2-2.5 mm (excluding awn), green costa 3-veined, excurrent into an awn 1-2.5 mm. Utricles green, longer than glume, rhombic-elliptic, 3-3.5 mm, membranous, sparsely puberulent, many veined, irregularly excavated, base attenuate, shortly stipitate, apex contracted into a short conic beak, orifice 2-toothed. Nutlet tightly enveloped, ovate, trigonous, ca. 2 mm, with angles contracted at middle, with faces excavated both in upper and lower parts, base shortly stipitate, apex discoid-annulate; style short, base conically thickened; stigmas 3.

Description Rhizome short, woody. Culms tufted, 15–50 cm tall, trigonous, scabrous, base with gray-brown or brown persistent sheaths splitting into fibers. Leaves shorter or longer than culm; blades 1.5–3 mm wide, herbaceous, flat, lower margins scabrous. Bracts leaflike or short-leaflike; lower ones longer than spikes, upper ones shorter, with sheaths 5–25 mm long. Spikes 3–5, upper ones close together; terminal spike male, clavate-cylindrical, 1–3 cm long, 1.5–3 mm wide, with short peduncle; lateral spikes female, narrow cylindrical, 1–2.5 cm long, 2–3 mm wide, flowers somewhat densely arranged, spike peduncles hidden in bract sheaths. Male glumes obovate-oblong, 4–5 mm long, pale yellow or pale brown, apex rounded, back with 3 green-brown midveins, extending into a short point or rough short awn. Female glumes obovate or obovate-oblong, 2–2.5 mm long (excluding awn), pale green or whitish, apex shallowly emarginate or rounded, back with 3 green midveins extending into a rough awn 1.5–4 mm long. Utricles fusiform-ovoid, obtusely trigonous, 3–3.5 mm long, shorter than female glumes, green or yellow-green, membranous, with many fine nerves, sparsely short hairy, base gradually narrowing into short stipe, apex tapering into beak 0.5–0.7 mm long, beak orifice with 2 small teeth. Nutlet tightly enclosed in utricle, rhombic-ellipsoid, trigonous, 1.8–2.2 mm long, chestnut-brown, apex abruptly contracted into annulate disc, mid-section of angles constricted, upper and lower faces concave, base with short stipe; style base thickened; stigmas 3.
