Perennial, occasionally annual, tufted or rhizomatous, stout or slender herbs. Stems terete or 3-angled. Leaves flat or keeled with well-developed laminae, or filiform, reduced to basal sheaths. Inflorescence varying in number of spikelets and degree of branching, from a terminal, much-branched ± umbellate panicle with several leafy bracts, to an apparently lateral single spikelet or small cluster of spikelets, with subterete green bract appearing as a prolongation of the stem. Spikelets usually many-flowered. Glumes spirally imbricate round rhachilla, all floriferous or lower 1–(2) empty; flowers hermaphrodite. Hypogynous bristles c. 6, or often 0. Stamens 3 or fewer. Stigmas 3 or 2. Nut usually obovoid or ellipsoid, trigonous, plano-convex or biconvex.
