Plants with short-creeping rhizomes, forming dense colonies. Culms brown to chestnut at base, surrounded by remains of old leaf-bases, but not conspicuously fibrillose; flowering culms 30–80 mm, usually longer than leaves at maturity, 1–2 mm thick, glabrous but finely scabrous within inflorescence. Leaves: sheaths glabrous, basal ones dark chestnut, grading to light-brown and green on back, all bearing blades, sometimes very reduced in size on basal ones; sheath fronts brown-hyaline or membranous, darker brown and often red dotted toward apex; blades rigid, flat or channeled near base, 2.5–7 mm wide, glabrous but margins, edges of adaxial surface, and midrib of abaxial surface finely scabrous. Inflorescences: peduncles of lateral spikes slender, to 100 mm (proximal spikes) or to 30 mm (distal spikes), minutely scabrous; of terminal spike 3–20 mm, glabrous; proximal bracts much shorter than inflorescences; sheaths 10–75 mm; blades 1.5–3.5 mm wide. Lateral spikes 4–12, 1–3 per node; proximal spikes well separated, arching, pistillate with 20–50 perigynia attached 1 mm apart, cylindric, 15–45 × 6–9 mm; distal spikes androgynous or staminate, usually crowded near apex. Terminal spike staminate, sometimes compound at base, 20–60 × 2.5–4 mm; the set of predominantly staminate spikes usually conspicuously raised above predominantly pistillate ones. Pistillate scales pale hyaline tinged with light-brown, with midrib green to golden green, ovate to elliptic, nearly as long as mature perigynia, gradually narrowing to acuminate or short-cuspidate apex, glabrous except scabrous midrib. Perigynia green to straw colored, sparsely red dotted, 2-ribbed and finely 7–10-veined, slightly inflated around achene, ovoid, 5–6.5 × 1.5–2.5 mm, membranous, base rounded, apex gradually tapering to beak, glabrous; beak bidentate, 2.5 mm including teeth, teeth hyaline, narrow, to 1 mm. Achenes substipitate, 2–2.5 × 1.2–1.7 mm.


Phenology: Fruiting late spring–early summer.
Habitat: Floodplain forests, mesic deciduous forests, wet clearings and swamp forests, stream banks, acid seeps, margins of sinkholes, dolomite glades
