Description Rhizome short. Culms densely tufted, 5-20 cm tall, slender, smooth, compressed trigonous, 2-leaved in lower 1/3. Basal sheaths with blades, pale brown, not split into fibers; blades slightly shorter to slightly longer than culm, linear, flat, ca. 1 mm wide, smooth, margins scabrid. Inflorescence 1-spiked, terminal, androgynous, pale brown, ovate-elliptic, 1-1.3 × ca. 0.5 cm; male part short, 3-6-flowered; female part longer than male part, densely many flowered, bractless at base. Female glumes pale brown, oblong, ca. 3.5 mm, 1-veined. Utricles ovate-elliptic, ca. 4 mm (including stipe ca. 1 mm), membranous, not distinctly veined on both surfaces, apex gradually attenuate into a short beak, orifice subtruncate. Nutlet elliptic-orbicular, ca. 1.5 mm, lenticular, without or with a very short rachilla at base; stigmas 2. [details]
