Anuales o perennes, la mayoría pequeñas. Tallos solitarios o próximos entre sí, brotando de un rizoma rastrero, o cespitosos, erectos, teretes, acostillados, filiformes, rígidos, foliosos en la base. Hojas más cortas que el escapo floral, espirales, filiformes, aplanadas o acanaladas, el margen abierto en la garganta de la vaina, generalmente largamente ciliado. Inflorescencia una sola espiguilla terminal o un corimbo umbeliforme simple o compuesto, abierto o subcapitado; brácteas 1 o más, foliiformes. Espiguillas bisexuales, sésiles o pediceladas, cimosas en el desarrollo cuando no solitarias. Glumas espiraladas o raramente subdísticas, deciduas, las inferiores generalmente estériles, la costilla media prominente y generalmente formando una quilla curvada verde, con o sin un mucrón excurrente; raquilla persistente. Flores bisexuales; perianto ausente; estambres 1-3; estilo terete o triquetro, liso, la base hinchada y generalmente persistente sobre el aquenio; estigmas 3. Aquenios trígonos a subrotundados o aplanado-convexos, redondeados u obtusos en la punta, la base del estilo (tubérculo) más o menos persistente, los ángulos frecuentemente redondeados, las caras transversalmente ruguladas, papilosos o reticulados, frecuentemente con diminutas papilas o puntos verticalmente orientados. 80 o más spp. Latitudes templado cálidas a tropicales.

Hojas con láminas alambrinas, generalmente escábridas o hírtulas; vaina cerrada, ápice piloso-ciliado. Escapos filiformes, más largos que las hojas; espiguillas amontonadas en capítulos terminales o cimas paniculiformes difusas de espiguillas o glomérulos de espiguillas, o solitarias y terminales, espiguilla con escamas imbricadas en espiral, todas fértiles excepto las 1 ó 2 inferiores; cerdas del perianto ausentes; anteras 1–3, 2- ó 4-loculares; carpelos 3, estigmas lineares y subiguales. Fruto mayormente triquetro, ápice con la base abultada y persistente del estilo.

    Herbs, annual or perennial, cespitose, scapose, not rhizomatous. Roots diffuse, very fine. Culms stiff or flaccid, usually terete, ribbed. Leaves basal, polystichous, spreading to ascending; sheaths open apically, apex fimbriate-ciliate, rarely entire; ligules absent, lateral tufts of hair at junction of blade and sheath; blades mostly linear or filiform, coarsely ribbed, usually longer than sheaths, 1 mm wide or less, mostly strongly involute, margins variably scabrid-ciliate. Inflorescences terminal on slender scapes, rarely axillary to culm leaves, simple or compound anthelae or spikelet solitary; spikelets 1–50+; involucral bracts (1–)2–8, spreading or erect, leaflike or scalelike. Spikelets mostly ovoid to lanceoloid or lance-cylindric; scales 6–50, spirally arranged, rarely nearly distichous, each subtending flower or 1–2 proximal scales empty. Flowers bisexual; perianth absent; stamens 1–3; styles slender, (2–)3-fid, glabrous, base enlarged, persistent in fruit. Achenes trigonous or 3-lobed, rarely biconvex, usually 3-ribbed.

    "Spikelets mostly in simple or compound, often umbelliform cymes (or virtually a head) forming a terminal infl subtended by 2–several slender, ± lf-like invol bracts; scales spirally imbricate; fls perfect; perianth none; stamens 1–3; style trifid, the unbranched portion smooth, the base enlarged and usually persistent on the trigonous achene as a tubercle (minute in our spp.); radicle basal; herbs with mostly basal, filiform to narrowly linear lvs, the sheath long-ciliate or fimbriate at the top. 80+, mainly trop. B. stenophylla (Elliott) C. B. Clarke, a coastal plain sp., closely approaches our range in N.C. and may be sought in se. Va. The stems have a single dense terminal cluster of virtually sessile spikelets, subtended by elongate, setaceous invol bracts."
