Plants cespitose. Culms straight or arcuate, 2–85 cm. Leaves of flowering stems shorter than to exceeding culms, to 20 cm × 0.8–5.4 mm; ligules on distal cauline leaves usually obsolete (except in 414.b Carex viridula subsp. brachyrrhyncha). Inflorescences: peduncles of terminal staminate spikes 0–28 mm; bracts to 18 cm × 0.6–3.4 mm; inner band of sheaths concave or truncate. Spikes: proximal pistillate spikes 1–8, contiguous or proximal distant, sessile or short-pedunculate, globose to short-cylindric, 4–17.5 × 3–11 mm; terminal staminate spike sessile or pedunculate, 5–25 × 1–3.6 mm. Scales: pistillate scales pale brown to reddish brown, 1.4–3.2 × 0.8–1.7 mm, margins pale, narrow, hyaline; staminate scales reddish brown, lanceolate to ovate, 2.3–5.2 × 0.7–2 mm, margins narrowly pale hyaline, apex obtuse to acuminate. Anthers 0.9–3.1 mm. Perigynia spreading, yellow to dark olive, 1.8–4.2 × 0.8–2 mm, apex gradually or abruptly narrowed; beak straight or reflexed less than 20°, 0.3–2.1 mm, scabrous or smooth. Achenes 1–1.8 × 0.7–1.4 mm.
