Description Rhizome short. Culms tufted, 20-45 cm tall, slender, obtusely trigonous. Basal sheaths dark brown, split into fibers. Leaves longer than culm, blades 1-2.5 mm wide, flat, margins scabrid. Lowest involucral bract leafy, longer than subtending spike, shortly sheathed, sheath 1-1.5 mm. Spikes 2 or 3; terminal spike male, clavate, 8-15 × 3-4 mm, with peduncle 5-9 mm; lateral spikes female, orbicular to ovate or oblong, 4-7 × 3-4 mm, densely flowered, with short peduncle 2-4 mm. Female glume pale brown, broadly elliptic or obovate-oblong, ca. 2.5 × 1.2 mm, membranous, green costa 1-veined, excurrent into a scabrid mucro. Utricle pale yellowish green, longer than glume, rhombic-elliptic or broadly ovate, obtusely trigonous, ca. 2.5 mm, puberulent, distinctly veined abaxially, faintly veined adaxially, base abruptly contracted into a very short stipe, apex abruptly contracted into a conic beak, orifice 2-toothed. Nutlet pale brown, tightly enveloped, ovate, trigonous, ca. 1.5 mm, apex discoid-annulate; stigmas 3. [details]
