Description Rhizome short; shoots densely tufted. Culms erect, terete to trigonous, smooth or scabrous, 3–10(-20) cm long, c. 0.7 mm diam. Leaves exceeding culms, to 35 cm long; blade 2–3 mm wide; sheath yellow-brown; ligule obtuse to truncate. Inflorescence erect, narrow, c. 4 cm long, with 2–5 spikes solitary at nodes; lowest involucral bract exceeding inflorescence. Spikes sessile, contiguous, erect at maturity, 1.2–1.8 cm long; uppermost spike male; lower spikes female. Glumes obtuse to acuminate, often long-mucronate (mucro to 2 mm long), whitish to pale brown with green midrib; female glumes 2.5–4.5 mm long. Perigynia (utricles) ellipsoid, prominently numerous-nerved, 2–3.3 mm long, 1.0–1.5 mm diam., hispid, pale green to yellow-brown; beak c. 0.5 mm long, with apex notched. Anthers 1.8–2.5 mm long excluding appendage to 0.1 mm long. Style 3-fid. Nut obovoid to ellipsoid, trigonous in cross section, pale yellow, with enlarged disk-like junction with persistent style base. [details]

Description Rhizomes short, woody, sometimes with stolons. Culms tufted or densely tufted, lateral or central, 8–40 cm tall, obtusely trigonous, slender or somewhat robust, smooth, with pale brown or brown persistent leaf sheaths at the base, splitting into fibrous strands. Leaves shorter than the culms; leaf blades 0.5–6 mm wide, herbaceous, rarely leathery, flat or margins revolute, abaxially and marginally scabrous. Lowest bract leaf-like or short-leaf-like, longer than the spikes; upper bracts usually bristle-like, with a short sheath 1.5–6 mm long, sometimes the lowest sheath up to 2.2 cm. Spikes 2–5, the upper ones close together, the lowest slightly distant; terminal spike male, clavate-cylindrical or short-cylindrical, 1–1.5(3) cm long, 2–3 mm wide, nearly sessile or shortly pedunculate; lateral spikes female, sometimes with a terminal portion of male flowers, short-cylindrical or rarely cylindrical, 0.3–1.5(4) cm long, 3–4(5) mm wide, flowers densely arranged or with only 3–8 flowers; peduncles usually hidden within bract sheaths, rarely slightly exserted. Male glumes oblong-obovate or narrowly obovate, 3.5–4.5 mm long, green-white or yellow-white, apex gradually acute or sharply acute, dorsal surface with 3 green midveins, sometimes extending into a short to long awn. Female glumes ovate, obovate or oblong-obovate, 2–2.5 mm long (excluding awn), green-white or yellow-white, apex gradually acute or slightly emarginate, with 3 green midveins extending into a 2–3.5 mm scabrous awn, sometimes short-awned. Utricles obovoid-globose, obtusely trigonous, 2–3.5 mm long, nearly equal to or slightly longer than the female glumes, pale green or yellow-green, membranous or papery, with multiple fine veins, sparsely or densely short-pubescent, sometimes very sparsely puberulent or glabrous, base gradually narrowed into a short stipe, apex gradually constricted into a 0.2–0.3 mm conical beak, sometimes with a 0.5–1 mm beak, beak aperture slightly concave or with 2 small teeth. Nutlets tightly enclosed in the utricle, obovoid-globose, trigonous, (1)1.5–2.5 mm long, chestnut-colored, apex sharply contracted into an annular disk, base gradually narrowed; style base thickened; stigmas 3. [details]
