Rhizomes to 1.5 cm or shorter, knotty. Culms loosely cespitose, 15–45 cm, base sometimes swollen. Leaves: basal leaves 4–15 cm × 2–7 mm, margins pilose to sparsely hairy, apex not callous. Inflorescences: glomerules 4–15, central glomerules sessile or nearly sessile, broadly conic or globose (often loosely flowered); peduncles straight, divergent by as much as 90°, to 9 cm; proximal inflorescence bract leaflike, not longer than inflorescence; bracts and bracteoles clear, variously cut. Flowers: tepals greenish to pale or dark brown, usually with clear margins and apex, 2.8–4 mm; anthers ca. 2–5 times filament length; stigmas 2–3 times length of styles. Capsules pale to dark brown, obovoid to subglobose, usually shorter than tepals. Seeds dark brown, globose, 1.2–1.6 mm; caruncle 0.5–0.6 mm. 2n = 12.
