Description Rhizome long, woody, covered with dark brown fibrous remnants of basal sheaths. Flowering culms arising from axils of leaves, 12-30 cm tall, compressed trigonous, scapelike, flaccid. Leaves longer than culm, blades 6-15 mm wide, flat, smooth, leathery, margins scabrid. Involucral bracts bristlelike, sheathed, sheath 5-15 mm. Spikes 6-10, nearly all (at least terminal one) androgynous, oblong or cylindric, 8-25 mm, loosely flowered; male part short, 3-5 mm; peduncle 7-25 mm, slender. Female glumes pale brown to yellow-green, ovate-oblong, ca. 2.2 mm, costa green, apex acute or mucronate. Utricles yellow-green, longer than glume, oblong-rhombic to obovate-fusiform, obscurely trigonous, 4-5 mm, membranous, densely puberulent above and ciliate on margins, many veined, base cuneate, with a stipe ca. 1 mm, apex attenuate into a short beak, orifice minutely 2-toothed. Nutlets trigonous, rhombic, 2.5-3 mm, faces excavated in both upper and lower parts, angles constricted at middle; style base persistent, bent; stigmas 3. [details]

Taxonomy Rhizomes elongated, woody, robust; culms lateral, 10–35 cm tall, flattened-trigonous, flexible, slightly scabrous, bases covered with pale brown to brown sheaths splitting into fibers; leaves longer than the culm, blades 6–16 mm wide, coriaceous or subcoriaceous, spreading, both surfaces smooth, margins and apex scabrous; bracts shortly setaceous with sheaths 5–18 mm long, sometimes with a lateral inflorescence on the lower bracts; spikes 6–10, androgynous, cylindrical, 9–25 mm long, flowers moderately dense, male portion 3–5 mm long; peduncle 7–20 mm, hidden or slightly exserted; male scales ovate to broadly ovate, 2–2.5 mm long, yellowish-brown, apex rounded, with 3 pale green veins; female scales broadly ovate, 2.2–2.5 mm long, yellowish-brown or yellow-green, apex rounded or acute, with 3 pale veins; perigynia rhomboid-obovoid or obovoid, obtusely trigonous, 3.5–4.5 mm long, membranous, with numerous fine veins, apex and margins densely pubescent; achenes rhomboid-ellipsoid or rhomboid-obovoid, trigonous, lateral faces convex and upper and lower faces concave, 2.5–3 mm long, style persistent, twisted or straight, stigmas 3.
