Description erennial, rhizome rather long, obliquely ascending, slender stoloniferous. Culms loosely tufted, 13–20 cm tall, slender, acutely triquetrous, minutely scabrous, lurid and bladeless sheathed at base, rudimentary sheaths usually disintegrating into fibers. Leaves shorter than or nearly longer culm, blades 1–1.5 mm wide, conduplicate or involute, scabrous on upper surface and margins; sheaths pallid, with distinctly pallid veins. Involucral bracts shortly sheathed, lowest involucral bract leaflike, upper ones setiform. Spikes 2 or 3, lowest spike rather remote, upper ones rather approximate; terminal spike male, clavate-linear, 1.5–2 cm, with a slender peduncle; lateral spikes female, oblong, 8–13 mm, densely few- to several-flowered, with a slender peduncle. Male glumes yellowish brown, oblong-ovate, ca. 4 mm, membranous, with white or pale-green midrib, apex acute. Female glumes ochroleucous-brown, ovate, ca. 3 mm, membranous, with a white or pale-green midrib, apex acuminate or acute. Utricles brownish, obliquely patent, equaling or slightly shorter than glume, elliptic, obtusely trigonous, 2.5 mm, leathery, glabrous, apex abruptly contracted into a short beak, emarginate. Nutlets obovate-lliptic, trigonous, 1.5 mm; style base slightly thickened; stigmas 3.  [details]
