Description Rhizomes short. Basal sheaths few, pale brown, dull, not retaining dried leaf blades. Culms tufted, erect, trigonous or subterete, (1.5-)6-45 cm tall, slender, 0.5-1.1 mm in diam. Leaves basal or sub-basal, shorter than or equaling culms, sometimes curved; blade V-shaped in transverse section, inrolled, 1-2 mm wide, midrib not distinct abaxially. Inflorescence a loose or sometimes slightly compact panicle, yellowish brown, or green and partly brown, linear or narrowly cylindric, sometimes curved, 1-8 × 0.2-0.7 cm; branches mainly androgynous, subequal in length, appressed or slightly spreading; lower inflorescence branches compound or simple, linear-oblong to ovate; lowest involucral bract leaflike, usually surpassing inflorescence. Spikelets usually unisexual (occasionally bisexual); glumes pale yellow to brown, sometimes marked with brown spots and lines, ovate or oblong, 2-3.5 × 1-1.7 mm, midvein green, broad, margin hyaline, apex aristate, acute, or rounded. Prophylls pale yellow or pale green, sometimes with reddish brown spots and lines, utriculiform, oblong, narrowly elliptic, or narrowly ovate to lanceolate, 2.4-3.5 × 0.8-1.5 mm, membranous, 2-keeled, keels slightly scabrid or smooth, margins fused to apex. Nutlets pale yellow or brown, narrowly oblong or elliptic-obovoid, trigonous, 1.5-2.5 × 0.5-1 mm, shortly beaked. Rachilla in female spikelets longer than nutlet, included in prophyll, green, flat, margins scabrid. Stigmas 3. Fl. and fr. Jun-Sep. [details]
