Culms densely to loosely cespitose, 10–40 cm. Leaves: basal leaves 3.5–12 cm × 2–6 mm; cauline leaves equaling or exceeding inflorescences. Inflorescences: glomerules 3–16 (each with 8–16 flowers), 1–2 nearly sessile with others on evident peduncles, mostly cylindric; secondary branches sometimes present, usually straight, erect; proximal inflorescence bract barely as long as to exceeding inflorescence. Flowers: tepals pale brown to chestnut brown to blackish with clear margins, 2–4 mm; outer and inner whorl ± equal, or outer whorl slightly longer (outer whorl pointed, inner whorl pointed or truncate-mucronate); anthers not more than 2 times filament length; stigmas 0.8–1.5 mm; styles not persistent in fruit. Capsules pale to brown to black, globose, shorter than to ± equaling tepals. Seeds 1.1–1.7 mm; caruncles 0.2–0.6 mm.
