Description Perennial herbs. Rhizomes short, stiff. Culms loosely caespitose, central or lateral, 9–18 cm tall, trigonous, slender, white pilose, with grayish brown, persistent sheaths at base. Leaves shorter than to rarely longer than culms; blades 2.5–6 mm wide, flat, scabrous on distal margins, white pilose on both surfaces. Involucral bracts spathaceous, shorter than inflorescence, pale reddish brown, sheathing; sheaths 6–13 mm long, with the proximal one longer than the others. Spikes 3 or 4; terminal spike staminate, narrowly clavate, 9–13 mm long, ca. 1 mm wide, with a short peduncle at base; lateral spikes pistillate, remote, shortly cylindrical, 6–11 mm long, 2–3 mm wide, 5–8-flowered. Staminate scales narrowly ovate, 2.8–3 mm long, pale reddish brown, acuminate at apex, with costa green, 1-veined. Pistillate scales ovate, ca. 2 mm long, pale reddish brown, acuminate at apex, with costa green, 3-veined. Perigynia longer than pistillate scales (including beak), ellipsoid, trigonous (excluding beak), 3–3.5 mm long (including beak), pale yellow, densely white pilose, thinly veined, attenuate at base, gradually contracted into a ca. 0.5 mm long beak at apex; orifice 2-lobed with minute teeth. Achenes tightly enveloped, ovoid, trigonous, castaneous, ca. 2.5 mm long, shortly stipitate at base; styles glabrous, not thickened at base; stigmas 3. [details]
