Plants perennial; rhizomes horizontal, elongate. Culms erect, slender, 15–65(–75) cm, hairy or glabrous. Leaves: sheaths green to brownish or reddish, not or scarcely winged, weakly ribbed, hirsute or glabrous; contra-ligule minute, obtuse, or absent; blades linear, ribbed, usually much shorter than inflorescences, 1.5–4(–5) mm wide, pubescent or more rarely glabrous. Inflorescences terminal, unbranched, glomerate-spicate, 4–8(–12) cm; glomerules 3–9(–11), inserted in longitudinal concavities in rachis, open, nodding or reflexed, greenish to reddish brown, 4–7 mm wide, each with 2–7(–8) spikelets; bract occasionally subtending proximalmost glomerule, attenuate, 1–2.5 cm. Spikelets bisexual and staminate, 4–5 mm; staminate spikelets many flowered; staminate scales lance-acuminate, pistillate scales ovate-acuminate. Achenes sordid white or gray, trigonous, ovoid to subglobose, 1–2 mm, smooth, shining, base broadly cuneate-attenuate, apex mucronate, hypogynium obsolete, represented by narrow brownish ridge or band at base of achene.
Phenology: Fruiting spring–fall.
Habitat: Moist sandy or sandy-peat soil in savannas, pinelands, or meadows, also in peaty bogs, seepage areas
Elevation: 0–100 m
Distribution
Ala., Fla., Ga., La., Miss., N.C., Tex., Mexico, West Indies (Cuba, Hispaniola, Jamaica), Central America, South America, Africa.
Discussion
Scleria distans is widespread in tropical America and Africa. Temperate North American material has often been called Scleria hirtella Swartz (J. E. Fairey 1967; J. W. Kessler 1987); E. A. Robinson (1964) used the name S. nutans for those plants. The name S. hirtella properly belongs to an annual species of tropical America (C. D. Adams 1994b).
