Description Rhizome short, stoloniferous. Culms 40-50 cm tall, slender, smooth, clothed at base with brown, bladeless, lustrous sheaths. Leaf blades 2-2.5 mm wide, flat, margins scabrous. Involucral bracts leaflike, equaling or slightly longer than inflorescence, sheathless. Spikes 3 or 4; terminal spike male, linear, 1-2.5 cm; remaining spikes female, slightly overlapping, cylindric, 1-2 cm, densely many flowered, subsessile. Female glumes brownish purple-red, light green abaxially, oblong-ovate, 1.5-1.7 mm, 1-veined, apex obtuse, sometimes with mucro. Utricles longer than glume, broadly obovate or suborbicular, rarely ovate or elliptic, plano-convex, 2-2.5 mm, thinly membranous, 3-5-veined, base very shortly stipitate, apex abruptly contracted into a short beak, orifice emarginate or 2-toothed, rarely apex beakless. Nutlets tightly enveloped, obovate, ± biconvex; style base not thickened; stigmas 2. [details]
