Plants densely cespitose, short-rhizomatous. Culms 5.5–20 cm. Leaves: basal sheaths reddish brown, blades mostly basal, pale green, shorter than culms, thin, 1–3.1 mm wide. Inflorescences: peduncles of proximal spikes short; peduncles of terminal staminate spikes 1–3.1 mm; proximal bracts short-sheathing; pistillate spikes 2–3, emerging from cauline nodes, aggregated, ascending, ovoid to ellipsoid; terminal staminate spikes 5–6.8 × 1.1–1.5 mm. Scales: pistillate scales reddish brown, ovate, apex obtuse, minutely ciliate. Anthers 1.3–1.4 mm; staminate scales dark reddish brown, ovate, margins white, apex obtuse to rounded, scarious. Perigynia ellipsoid, 2.3–3.3 × 1.1–1.4 mm, base cuneate, pubescent with coarse, wrinkled white hairs; beak straight, 0.3–0.4 mm. Stigmas 3, thin, flexuous, strongly papillose. Achenes ellipsoid, 1.7–2.1 × 1–1.3 mm. 2n = 54.

Discussion

Carex concinna is common in northern Canada and Alaska, particularly in the western mountains in the montane zone. It is often abundant, along with C. richardsonii, on open gravelly or sandy banks of spring flood channels. Superficially, C. concinna looks quite similar to C. deflexa Hornemann and C. rossii Boott of sect. Acrocystis. It differs from them in its strongly sheathing, short-bladed bracts, perigynium indument of coarse, wrinkled hairs, and minutely ciliate pistillate scale apices.
