Inflorescencia un fascículo de espiguillas simple o terminal, o una o más cimas densas compuestas de glomérulos, o a veces espiguillas pinnadas; espiguillas lanceolado-ovoides o cilíndricas, de muchas escamas suaves, marcadamente acostillado-cuspidadas, imbricadas en espiral, delgadas, verdosas, todas fértiles excepto unas pocas inferiores; flósculos perfectos, perianto en 2 series de cerdas, las 3 internas variadamente laminadas, las exteriores simples o, menos frecuentemente el perianto de una sola serie laminada o sin láminas; estambres (1) 2 ó 3 (–6); carpelos 3, estilo trífido, estigmas lineares. Fruto mayormente triquetro y estipitado con un rostro delgado pronunciado, éste articulado al ápice terete y deciduo del estilo.

    Herbs, perennial or annual, sometimes with a creeping rhizome. Culms tufted or solitary, usually pubescent, nodose. Leaves mostly cauline, pubescent or glabrous; sheath usually completely surrounding culm; ligule tubular, hyaline; leaf blade usually elongate, linear to lanceolate. Involucral bracts leaflike, sheathing at base. Inflorescences paniculiform, with few to many glomerulate clusters or sessile spikelets at few to several nodes. Spikelets ovoid to ellipsoid, terete, many flowered, usually pubescent. Glumes spirally imbricately arranged, obovate, broadly elliptic, or oblong, each subtending a bisexual flower but basal 1 or 2 empty, apex obtuse and awned. Perianth bristles 3 or 6, 3 outer ones needlelike (sometimes reduced or absent), 3 inner ones squamellate and alternate with outer whorl. Stamens 3. Style not or hardly dilated at base, continuous with ovary, glabrous; stigmas 3. Nutlet ± stipitate, obovoid to ovoid, 3-sided, ± smooth or tuberculate.

    Herbs, annual or perennial, cespitose or not, rhizomatous or not, variously pubescent. Culms solitary or not, 3–5-angled in cross section. Leaves all cauline, polystichous, usually hairy, hair sometimes confined to junction of blade and sheath; sheaths closed, tubular; ligules tubular, scarious; blades sometimes absent or reduced to mucro or cusp, flat, or those mid culm strongly formed. Inflorescences of spikelets sessile in clusters of 2–5 (rarely solitary), the clusters sessile or pedunculate and terminal or racemose; spikelets to 150. Spikelets: scales 20–50, spirally arranged, proximal 1–2 scales empty, others subtending flower, some distal scales empty. Flowers bisexual; perianth (3–)6 in sets of 3, outer set of stout, sharp bristles shorter than inner set of stipitate-bladed, spatulate scales, rarely inner set forked or pinnately lobed; stamens 1–3(–6), long-exserted; styles linear, 3-fid, articulate well distal to base, base usually persistent. Achenes trigonous-rhomboid.
