Description Rhizomes short. Basal sheaths prominent, pale brown to brown, dull, retaining dried leaf blades. Culms densely tufted, erect, obtusely trigonous, 2-15 cm tall, 0.8-1.5 mm in diam. Leaves basal, shorter than culms, sometimes recurved; blade flat, midrib distinct abaxially, folded at base, 1-2.2 mm wide. Inflorescence spicate, brown, densely cylindric, 0.8-1.7 × 0.4-0.6 cm, with up to 10 spikelets; lowest involucral bract glumelike, aristate. Terminal spikelets of inflorescence male, lower ones bisexual with 1 basal female flower and 2-7 distal male flowers. Glumes brown, with a yellowish green or green midvein, oblong, ovate-elliptic, or ovate, 3-5 × 1.5-2.5 mm, margin broadly hyaline, apex obtuse or rounded, sometimes aristate. Prophylls pale brown, oblong or elliptic, 3-5 × 1.5-2 mm, membranous, glabrous, 2-keeled, keels scabrid, margins open to base. Nutlets brown or grayish brown, narrowly obovoid or elliptic, trigonous, 2.5-3 × 1-1.5 mm, very shortly stipitate, shortly beaked. Stigmas usually 3. [details]
