Description Rhizome short, obliquely ascending, woody, hard. Culms tufted, lateral, 20–60 cm tall, bluntly trigonous, smooth or slightly rough, at the base with brown or dark-brown persistent leaf sheaths split into fibrous strips. Leaves longer than the culms; leaf blades 3–9 mm wide, herbaceous, flat-spreading, rough on the back and on the margins. Bracts leaf-like or short leaf-like, longer or shorter than the spikes, with a sheath, sheath 1–2.5(4) cm long. Spikes 4 or 5, distant from each other; terminal spike male, club-shaped cylindrical, 2–4 cm long, 2–4 mm wide; lateral spikes female, often with several male flowers at the apex and at the base, cylindrical or long-cylindrical, 2–5 cm long, 4–5 mm wide, flowers densely arranged, peduncles of spikes protruding from the bract sheaths, sometimes the uppermost ones enclosed in the bract sheaths. Male glumes long-elliptic-oblanceolate, lanceolate or narrowly ovate-lanceolate, 6.5–8 mm long, yellowish-white or pale yellowish-brown, apex rounded-obtuse or gradually acuminate, with 3 yellow mid-nerves on the back, extending into a short awn to a long awn. Female glumes ovate, long-ovate or obovate, 3–3.5 mm long (excluding awn), greenish-white, apex gradually acuminate, truncate or slightly emarginate, with 3 greenish-white mid-nerves on the back, extending into a rough long awn. Utricles rhomboid-ovoid-globose, bluntly trigonous, 2.8–4 mm long, shorter than the female glumes, pale yellowish-green, membranous, with many fine veins, sparsely covered with short soft hairs, base gradually narrowed into a short stalk, apex gradually narrowed into a beak 0.8–1 mm long, beak mouth with 2 small teeth. Nutlets tightly enclosed in the utricles, rhomboid-ovoid-globose, trigonous, 1.8–2.5 mm long, pale yellow, apex abruptly constricted into an annular disc, upper and lower faces of the angles depressed, base with a short stalk; base of style thickened; stigmas 3.

Description Rhizome short, obliquely ascending, woody. Culms tufted, 20-55 cm tall, slender, obtusely trigonous, clothed at base with brown sheaths disintegrating into fibers. Leaves longer than culm, blades light green, linear, 3-9 mm wide, leathery, margins scabrous. Involucral bracts shortly bladed, long sheathing. Spikes 4 or 5, distant; terminal spike usually male, rarely gynaecandrous, narrowly cylindric, 2.5-4.2 cm, peduncle 2.5-3.5 cm; lateral spikes female, usually with several male flowers at apex or base, subdensely flowered, peduncles erect, slender. Female glumes pale, oblong-lanceolate, rarely obovate-oblong, ca. 3 mm, green 3-veined costa excurrent into a scabrous long awn, apex truncate or sometimes emarginate or acuminate. Utricles yellow-green, longer than glume, obliquely patent, rhomboid or obovate, subinflated trigonous, 3-4 mm, membranous, sparsely puberulent, many veined, base gradually narrowed into a stipe, apex abruptly contracted into a beak of medium length, orifice 2-toothed. Nutlets tightly enveloped, rhomboid, trigonous, faces concave, apex abruptly contracted into a short beak, beak annulate at orifice; style base thickened; stigmas 3. [details]
