Description Rhizomes stout, horizontally creeping. Culms erect, green, 1-2.5 m tall, ca. 2(-3) cm thick, terete, smooth. Leaves mostly reduced to a sheath, glabrous; basal sheath brownish; apical 2 sheaths with leaf blades; leaf blade subulate to linear, 1-10 cm. Involucral bract 1, culmlike, subulate, as long as to slightly overtopping inflorescence. Inflorescence a pseudolateral simple or decompound anthela; rays 2-8, unequal in length, 5-8 cm. Spikelets reddish brown, oblong to ovoid, 0.6-1.5 cm, apex acute. Glumes ovate, abaxially glabrous, margin ciliate, apex emarginate with a 1-veined costa excurrent into a short awn. Perianth bristles 5 or 6, slightly longer than nutlet, retrorsely scabrous. Stamens 3; anthers linear, 1.5-2 mm; connective apex with a pyramidal-ovoid bearded appendage. Stigmas 3. Nutlet grayish, obovoid, ca. 3 mm, compressed 3-sided (ridge evident on abaxial surface when immature). Fl. and fr. Jun-Aug. 2n = 38, 42, 80. [details]

Description Rhizomes creeping, >10 mm thick. Stems up to 350 cm × 5–15 mm, terete, smooth, spongy, green to blue-green, with base thickened by leaf-sheaths. Leaves mostly reduced to bladeless sheaths; blade sometimes formed when plants submerged, 3–100 cm × 1.8–2.5 mm, linear-subulate; sheath up to 40 cm long, purplish-brown to mid brown, membranous and splitting early; ligule present, membranous, brown. Inflorescence terminal (often appearing to be lateral when young), compound, usually lax, with 3–10 flattened, scaberulous primary branches up to 10 cm long, sometimes with secondary branches up to 1.5 cm long; branches terminating in 1 to several spikelets; involucral bracts 2, subulate, with a membranous base, the lower up to 10 cm long, shorter to longer than inflorescence, erect and stem-like. Spikelets 6–15 × 3–5 mm, ovoid to ovoid-ellipsoid, acute to subacute, mid brown to dark reddish-brown. Glumes 2.5–4 × 1.5–3 mm, spirally arranged, broadly ovate, nerveless, mid brown to reddish-brown, with hyaline ciliate margins; surface with no or few papillae; apex emarginate with a substantial mucro; lateral lobes acutely pointed. Flowers bisexual; perianth bristles 4–6, ± equalling nut, retrorsely scabrid; stamens (2–)3, with anthers 2–2.5 mm; stigmas (2–)3.

Description Rizoma de entrenudos largos, hasta de 18 mm de diámetro. Tallos (30)50-200(300) cm × (1)3-12(15) mm, de sección circular, verdes o glaucos. Hojas reducidas a vainas, herbáceas o algo escariosas, frecuentemente teñidas de color púrpura oscuro, que cuando se deshacen forman una estructura fibrosa de apariencia pinnada, a veces con una lámina hasta de 30 cm, de menor longitud que su vaina, anchamente acanalada. Inflorescencia (1,5)2-8,5(15) cm, con (5)12-75(100) espiguillas dispuestas en glomérulos ± laxos, fascículos o formando una antela simple o compuesta; en este último caso, las ramas terminales llevan (1)2-4(6) espiguillas; ejes de la inflorescencia acanalados, con los bordes antroso-escábridos; bráctea inferior (5)10-40(60) × 1-4,5 mm, por lo general de menor longitud que la inflorescencia, erecta, oblicua o raramente patente, cilíndrica hacia el ápice; espiguillas (3,5)5-18(23) mm, de contorno ovado a ovalo-lanceolado, a veces subglobosas, con (6)12-44(50) flores. Glumas 2,5-4,3(4,5) × (1,3)1,6-2,8(3) mm, ovales, de ápice generalmente emarginado y mucronado, con la escotadura de (0,1)0,2-0,6(0,9) mm; ápice de los dientes agudo y mucrón sinuoso o recto de (0,2)0,4-0,8(1,3) mm, frecuentemente antroso-escábrido; superficies lisas o con indumento espinuloso-papiloso; bordes glabros o ciliados; de color pardo-rojizo oscuro o pardo anaranjado, a veces hialinas o casi de ordinario finamente punteadas, por lo general con una banda central más clara y en ocasiones con el margen escarioso. Anteras 1,4-1,9 mm, frecuentemente enrolladas en espiral, amarillas o anaranjadas, apiculadas; estilo con 2-3 estigmas, a veces ambos tipos en la misma inflorescencia. Aquenios (1,7)1,8-2,8(3) × (1,3)1,5-2,2 mm, de contorno generalmente obovado u obpiriforme, obtusamente trígonos o plano-convexos, lisos o, excepcionalmente, con alguna espínula dispersa, amarillentos cuando jóvenes, grisáceos o negruzcos en la madurez, mates o poco brillantes; cerdas periánticas 4-7(8), menores o iguales que el aquenio, más raramente algo mayores, a veces 2 o 3 de menor longitud que las demás, filiformes, retrorso-escábridas, con los acúleos de similar longitud, de pardo-rojizas a doradas. 2n = 38, 42, 44. [details]

Translation Rhizome with long internodes, up to 18 mm in diameter. Culms (30)50–200(300) cm × (1)3–12(15) mm, circular in cross section, green or glaucous. Leaves reduced to sheaths, herbaceous or somewhat scarious, frequently tinted dark purple, which when disintegrating form a fibrous structure of pinnate appearance; sometimes with a blade up to 30 cm long, shorter than the sheath and broadly grooved. Inflorescence (1.5)2–8.5(15) cm, with (5)12–75(100) spikelets arranged in ± loose glomerules, fascicles, or forming a simple or compound anthela; in the latter case, terminal branches bear (1)2–4(6) spikelets; inflorescence axes grooved, with antrorse-scabrous margins; lower bract (5)10–40(60) × 1–4.5 mm, usually shorter than the inflorescence, erect, oblique or rarely spreading, cylindrical toward the apex. Spikelets (3.5)5–18(23) mm, ovate to ovate-lanceolate in outline, occasionally subglobose, with (6)12–44(50) flowers. Glumes 2.5–4.3(4.5) × (1.3)1.6–2.8(3) mm, ovate, apex generally emarginate and mucronate, with a notch (0.1)0.2–0.6(0.9) mm deep; teeth apex acute with a sinuous or straight mucro (0.2)0.4–0.8(1.3) mm long, frequently antrorse-scabrous; surfaces smooth or with spinulose-papillose indumentum; margins glabrous or ciliate; dark reddish-brown to brownish-orange in color, sometimes hyaline or usually finely punctate, generally with a paler central band and occasionally with scarious margins. Anthers 1.4–1.9 mm, frequently spirally coiled, yellow or orange, apiculate; style with 2–3 stigmas, sometimes both types present in the same inflorescence. Achenes (1.7)1.8–2.8(3) × (1.3)1.5–2.2 mm, generally obovate or obpyriform in outline, obtusely trigonous or plano-convex, smooth or exceptionally with a few scattered spinules, yellowish when young, grayish or blackish at maturity, dull or slightly glossy; perianth bristles 4–7(8), shorter than or equalling the achene, more rarely slightly longer, sometimes 2 or 3 shorter than the others, filiform, retrorsely scabrous, with aculei of similar length, brownish-reddish to golden. 2n = 38, 42, 44. [details]
