Inflorescencia corimboso-paniculada; brácteas foliiformes, desiguales. Espiguillas bisexuales, numerosas, generalmente más bien pequeñas, ovoides a elipsoides, agrupadas o solitarias al final de rayos primarios y secundarios, o los rayos obsoletos. Glumas espiraladas, ovadas o lanceoladas, deciduas, redondeadas por el dorso o superficialmente carinadas con una fuerte costilla media, las nervaduras laterales inconspicuas; raquilla persistente.

    Herbs, perennial, cespitose or not, rhizomatous or not. Culms solitary or not, ± trigonous. Leaves basal and cauline or all cauline; sheaths not fibrous; ligules present, rarely absent; blades flat or V-shaped in cross section, prominently keeled abaxially. Inflorescences terminal, sometimes also axillary in 1–3 distal leaves, subumbellate or corymbose-paniculate; spikelets 50–500; involucral bracts usually 3, leaflike. Spikelets less than 3.5(–5) mm diam.; scales 10–50, spirally arranged, each scale subtending flower, glabrous. Flowers bisexual; perianth of (0–)3–6 bristles; bristles straight or strongly curled, smooth, or variously toothed, or barbed, shorter to much longer than achene, not obscuring scales in fruit; stamens 1–3; styles (2–)3-fid, linear, base persistent. Achenes trigonous, biconvex or plano-convex, 0.6–1.8 mm, minutely papillose. x = 14.

Glumes spirally arranged, deciduous, each subtending a flower. Flowers bisexual. Perianth bristles 3-6, as long as to much longer than nutlet, deciduous with nutlet. Stamens 1-3.

    SCIRPUS L.

    Por Robert Kral

    Anuales o perennes, arrosetadas o caulescentes, cespitosas y/o rizomatosas o estoloníferas, culmos y escapos teretes o triangulares, sólidos; plantas hermafroditas. Hojas con o sin lámina; lígula presente o ausente. Inflorescencia variadamente involucrada, capitada o difusa, básicamente paniculado-cimosa; flósculos unibracteados, numerosos, las escamas imbricadas en espiral; cerdas del perianto ausentes a varias; estambres 1–6; carpelos 2 ó 3, ovario atenuado hacia el estilo pero no articulado con éste, entonces el cuerpo del fruto continuo con el rostro.

    Género con ca 300 especies de ambientes muy húmedos, en ambos hemisferios, pero la mayoría en áreas templadas y subtropicales; 3 especies se han colectado en Nicaragua y 1 más se espera encontrar. Los límites genéricos aún son discutibles.

    Annuals or perennials, the culms leafy below, or the leaves often reduced to sheaths; flowers perfect, the spikelets terete or slightly compressed; scales spirally imbricate; perianth of 1-6 bristles, or lacking; stamens 2-3; style 2- to 3-cleft, frequently deciduous; achene triangular or lenticular.

    "Scales spirally arranged, ± scarious; fls perfect, each in the axil of a scale; perianth of (1–)3–6 short to elongate bristles, or seldom obsolete; stamens 3, or sometimes fewer; style 2–3-cleft, either completely deciduous or more often deciduous above the base and leaving a slender tip on the achene; herbs, mostly of wet places, with variously arranged spikelets. 200+, cosmop. The diffuse centromere may contribute to the frequent interfertility of plants with different numbers of chromosomes."
