Description Rhizome slender, clothed with dark brown, bladeless sheaths, stoloniferous. Culms tufted, 10-30 cm tall, slender, obtusely trigonous, scabrid on upper part, brown sheathed at base, sheaths disintegrating into fibers. Leaves slightly shorter than culm, blades 1-2 mm wide, flat, scabrous on upper surface and margins, sometimes slightly revolute on margins when dry, long sheathed. Involucral bracts scalelike, rarely lowermost one subulate, green, long aristate. Spikes 2 or 3, congregated at top of culm, sometimes lowermost one slightly remote; terminal spike male, linear or fusiform, 0.7-1.5 cm, nearly sessile; lateral spikes female, globose or ovate, 4-7 mm, few flowered, sessile. Female glumes brown laterally, ovate, ca. 2.5 mm, with a pale midrib, hyaline on upper margin, apex acuminate, mucronate. Utricle yellowish green, slightly brown on upper part, obliquely patent, nearly equaling glume, elliptic or obovate, plano-convex-trigonous, 2.5-3 mm, laxly hispidulous, not veined, base cuneate, apex abruptly contracted into a short beak, hispidulous on margins of beak, orifice emarginate. Nutlets tightly enveloped in utricle, broadly obovate, trigonous, ca. 1.7 mm; style base not thickened; stigmas 3. [details]
