Plants annual, cespitose, to 30 cm, base soft, not bulbous; rhizomes absent. Leaves nearly distichous, mostly spreading, to 2/3 length of culms; sheaths ciliate, sheath backs often pilose-hirsute; ligule present, complete; blades narrowly linear, 1.5–2.5 mm wide, flat or shallowly concave, margins scabrid, abaxial surface scattered-pilose, hirsute-ciliate at least proximally. Inflorescences: anthelae simple or compound, open, divaricately branched, mostly as broad as long; scapes slender, 1 mm wide, distally slightly compressed; proximalmost involucral bract exceeding or shorter than anthela. Spikelets pale brown or red-brown, ovoid to lanceoloid, 5–6 mm; fertile scales broadly ovate, 1.5–2 mm, acute-to obtuse-angled, midrib short-excurrent as mucro. Flowers: stamens 1–2; styles 2-fid, flat, fimbriate. Achenes whitened-iridescent to brown, lenticular or pyriform-obovoid, 1 mm, cancellate, each face with 5–12 vertical rows of transversely oriented rectangular pits, achene margins distally papillose. 2n = 20.
