Description Perennial herbs. Rhizomes short, ligneous, stiff. Culms caespitose, 30–60 cm tall, obtusely trigonous, glabrous,
scabrous on upper margins, with many grayish brown sheaths at base. Leaves longer than culms, or nearly equal in length; blades 2–5.5 mm wide, scabrous on dorsal surfaces. Involucral bracts foliaceous, or upper ones setaceous, shorter than inflorescence, sheathing the culms; sheaths 10–40 mm long, with the most proximal one longer than the others. Spikes 3 or 4; terminal spike staminate, clavate, 5–6 cm long, 3–6 mm wide, with a long peduncle at base; lateral spikes pistillate, cylindrical, 2.5–4.5 cm long, 4–5.5 mm wide, densely flowered, sometimes branched at base, with a few staminate flowers at the top. Staminate scales lanceolate, 8–8.5 mm long, yellowish brown, acute at apex, with costa green, 3-veined. Pistillate scales ovate, 2.5–3 mm long, acuminate at apex, laterally brown, with costa green, 3-veined. Perigynia nearly equaling pistillate scales (including beak), obovoid (excluding beak), obtusely trigonous, ca. 3 mm long (including beak), green, glabrous, thinly veined, attenuate and shortly stipitate at base, gradually contracted into a ca. 0.7 mm long beak at apex; orifice 2-lobed with minute teeth. Achenes loosely enveloped, obovoid, trigonous, yellowish brown, 2–2.5 mm long, with angles constricted at the middle and surfaces excavated both above and below the middle, discoid-annulate at apex; styles thickened at base; stigmas 3.
