Description Perennial herbs. Rhizomes indurate, with slender stolons. Culms 40–60 cm tall, acutely trigonous, scabrous, with brownish bladeless sheaths at base (aphyllopodic). Leaves shorter than culms, or nearly equal in length; blades 3–6 mm wide, flat, scabrous on upper margins. Involucral bracts leaflike or shortly leaflike, lower ones longer than spikes, uppers nearly equaling spikes, not sheathed. Spikes 3 or 4, remote; terminal spike staminate, clavate, 3–4.5 cm long, ca. 3 mm wide, with a 3–5 cm long peduncle at base; lateral spikes pistillate, cylindrical, 2.5–5 cm long, 6–8 mm wide, densely flowered, the lowest long pedunculate, upper ones shorter. Staminate scales oblong-oblanceolate, pale brown, 4–4.5 mm long, acute at apex, green 1-veined costa. Pistillate scales oblong-ovate, pale green or whitish green, 2–2.5 mm long, acuminate at apex, green 1-veined costa excurrent into a mucronate. Perigynia longer than pistillate scales, horizontally patent at maturity, ovoid, trigonous, slightly inflated, 3.5–4 mm long, yellowish green, glabrous, distinctly veined, base broadly cuneate, gradually contracted into a short beak at apex; orifice 2-lobed with short teeth. Achenes loosely enveloped, obovoid-ellipsoid, trigonous, castaneous, ca. 1.5 mm long, not stipitate at base; style not thickened at base; stigmas 3, slender, 1.5–2 mm long, persistent. [details]
