Description Rhizomes long-creeping. Culms solitary (rarely 2–3 together), 10–56 cm. Leaves light green, cauline blades 5–36 cm × 2.1–5.9(–8.3) mm, widest leaves 2.8–8.3 mm wide. Inflorescences: peduncle of terminal spike 0.1–9.6 cm (2.6–9.6 cm if staminate spike 1); ligule of proximal bract 1.6–7.4(–9.4) mm; bracts shorter than to overtopping culms, longest bract blade (per plant) of distal lateral spike 6.2–18 cm. Proximal spikes sometimes staminate at apex, usually arising from proximal 1/2 of culms, (9–)13–37 × 4.8–7.8 mm. Terminal spike often with 1–3 much smaller staminate spikes near its base, 18–45 mm, separated from distal lateral spike (unless staminate). Pistillate scales triangular, elliptic, or ovate, 1.6–3.6 × 0.8–1.7 mm. Staminate scales with apex acute to awned. Anthers 2.4 4.6 mm. Perigynia olive green, ovoid to oblong-ovoid, 2.8 4.2 × 1.4–1.8 mm, 1.9–2.5 times as long as thick; beak 0.3 0.9 mm, bidentulate, teeth 0.1 0.3 mm. Achenes 1.9–2.7 × 1.2–1.6 mm. 2n = 64. [details]
