Description Plants perennial, densely cespitose, 30–50(–70) cm; rhizomes absent. Culms erect to excurved, filiform, leafy, stiff to lax. Leaves mostly slightly exceeded by culm; blades ± filiform, proximally flat to concave, distally tapering, to 1 mm wide, margins involute, apex trigonous, subulate. Inflorescences terminal; spikelet clusters 1(–2), dense, broadly turbinate to hemispheric; longer leafy bracts 1–2(–several), setaceous, overtopping inflorescence. Spikelets light brown, narrowly ovoid, 2–2.5(–3) mm, apex acute or acuminate; fertile scales 1.5–2(–2.5) mm, apex acute, midrib excurrent as cusp or awn 0.5–0.9 mm. Flowers: bristles absent, rarely reduced to nubbins, or rarely 1, then shorter than fruit body. Fruits 1 per spikelet, 1–1.8 mm; body with dark brown ends, broad pale midzone, lenticular, ± orbicular, 1–1.2 × 0.8–1 mm, surfaces smooth; margins sharp, flowing to tubercle; tubercle lowtriangular, 0.2–0.3(–0.5) mm, sometimes apiculate.
