Plants perennial; rhizomes clustered, nodulose, rather slender, to 3 mm thick, hard. Culms in tufts, usually filiform, very slender, 35–80 cm, base 1–2 mm thick, glabrous or nearly so, somewhat scabrous toward apex. Leaves: sheaths purple tinged, scarcely winged, glabrous or minutely pilose; contra-ligules ovate, quite short, rigid; blades attenuate, keeled, shorter than culms, 1–2.5 mm wide, usually glabrous or nearly so. Inflorescences axillary and terminal, fasciculate; fascicles (1–)2(–3), 10–18 × 4–8 mm, each with 1–5 spikelets, the lateral on long filiform peduncles; bracts subtending inflorescence leaflike, lanceolate, 3–9 cm, long acuminate-attenuate, usually glabrous. Spikelets bisexual and staminate, brown, 3–6 mm; staminate scales lanceolate-acuminate, pistillate scales ovate, midrib excurrent, awnlike. Achenes brownish gray or with dark longitudinal bands, ovoid, 1.5–2 mm, smooth, shining, apex distinctly umbonate; hypogynium somewhat reduced, obscurely 3-angled, low, covered with whitish siliceous, papillose-spiculose crust.
More
Very slender, to 8 dm, from long rhizomes; main blades 1–3 mm wide, long-attenuate, usually wholly glabrous; cymes 1, occasionally 2 or 3, the lower short-peduncled; bracts foliaceous, the lowest erect, 1–2 mm wide; scales as in no. 1 [Scleria triglomerata Michx.]; achenes white, apiculate, 1.5–2 mm, the body about as thick as long. Damp sandy or peaty soil on the coastal plain; L.I. to S.C. Perhaps better treated as S. triglomerata var. minor Britton. (S. triglomerata var. gracilis)
