Description Culms round or trigonous, filiform, wiry, angles proximal to spike blunt or sharp, 5–22 cm, ± equaling leaves. Leaves: basal leaf sheaths only slightly fibrillose when old; blades bright green, involute-cylindric, quill-shaped, 3–18 cm, 0.2–0.6 mm wide near base. Spike 8–20 × 2–5 mm; staminate portion 4–8(–10) mm. Proximal pistillate scales pale red-brown or golden brown with white or gold margins, broadly obovate, 2–4(–4.7) × 1.7–3.3 mm excluding awns, apex obtuse to awned. Staminate scales red-brown with white margins and pale midstripe, oblong-ovate, apex obtuse. Perigynia 3–9, appressed to ascending, white, usually with golden brown to red-brown area near beak and/or near base, obovate (or elliptic), 2.5–4.4 × 1.2–2 mm, body usually glabrous or sparsely hirsute near base of beak; beak 0.4–0.8(–1) mm, style base not conspicuously exserted from beak; rachilla absent. Achenes obovate to ovate, 1.5–2.7(–3) × (1–)1.2–1.5 mm. Stigmas ± brown. [details]
