General Description
Densely caespitose. Stems erect, 15–90 cm. Leaves basal and cauline; blades 1–5 mm wide. Inflorescence of 4 to 10 sessile spikes densely clustered into a globose to ovoid head; lowest bract scale-like. Spikes 4–10 mm long, all similar; female flowers above male. Perigynia ascending, green to brown, narrowly ovate, flattened, wing-margined, 3–4.5 × 1–1.5 mm, the beak, 1–1.5 mm long, serrulate below, entire above; stigmas 2. Female scales brown sometimes with a pale midstripe and margins, shorter but nearly as wide as the perigynia. Achene 2-sided, much smaller than the perigynium (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press. Fort Worth, TX).
