Description Rhizome short. Culms 10-20 cm tall, trigonous. Basal sheaths dark brown, split into fibers. Leaves longer than culm, blades 4-7 mm wide, flat, smooth, leathery. Involucral bracts leafy, much longer than inflorescence, sheathed. Inflorescence 3-5-noded; spikes many, 3-5 at each node; terminal spike male, linear, 17-45 × 1-1.5 mm, shortly pedunculate; lateral spikes female or mostly with male part at apex, narrowly cylindric, 3-4.5 cm, ca. 3 mm thick, subloosely flowered, sessile or shortly pedunculate. Female glumes ovate-oblong, 2.5-3 mm, ciliate, apex rounded. Utricles green, longer than glume, rhombic-fusiform, trigonous, 3.5-5 mm, membranous, many veined, glabrous or puberulent above, base cuneate, stipitate, apex gradually attenuate into a conic beak, beak ca. 1 mm, 2-toothed at orifice. Nutlet brown to dark brown, tightly enveloped, rhombic, trigonous, 2.5-3 mm, faces excavated in both upper and lower parts, base cuneate, shortly stipitate, apex with distinct short neck ca. 0.3 mm, neck shallowly concave at top, neck and angles yellowish white; style base slightly thickened; stigmas 3.

Description Rhizome short, woody. Culms lateral, hidden among the leaves, 8–20 cm tall, trigonous, smooth, with brown or gray-brown persistent leaf sheaths at the base, sometimes splitting into fibrous strips. Leaves longer than the culms; leaf blades (3)4–7 mm wide, nearly leathery, spreading, smooth. Bracts leaflike, longer than the spikes, with sheaths up to 1 cm long. Spikes 7–12, sometimes fewer, borne on 3–5 nodes, with 2 or 3 spikes inside each bract sheath arranged in a short raceme, sometimes solitary; terminal spike male, clavate, 1.5–4.5 cm long, 1–1.5 mm wide, with a short peduncle or nearly sessile; lateral spikes androgynous or female, the male portion having only several male flowers, long-cylindrical or cylindrical, (1)1.5–5 cm long, 3–4 mm wide, flowers sparsely arranged, spike peduncle usually exserted from the bract sheath. Male glumes ovate-elliptic, about 3 mm long, pale brown, apex rounded, ciliate, dorsal surface with 3 yellow mid-nerves. Female glumes obovate or obovate-elliptic, 2.5–3 mm long, pale yellow-brown, apex rounded, ciliate, dorsal surface with 3 green mid-nerves. Perigynia fusiform-ovoid, obtusely trigonous, 3.5–4 mm long, longer than the female glumes, pale yellow-green, membranous, with many fine nerves, glabrous, base cuneate, apex gradually narrowing into a conical beak 0.5–1 mm long, beak orifice with 2 small teeth, upper margins of the beak slightly hairy. Achenes tightly enclosed in the perigynia, rhomboid-ovoid, trigonous, 2.5–3 mm long, chestnut-colored, apex contracted into a short necklike beak about 0.3 mm long, the beak yellow, top surface flatly concave, the middle of the lateral faces convex forming a waistlike swelling, upper and lower faces concave, base with a short stipe; style base slightly thickened; stigmas 3.
