Rhizomes short, stocky. Culms cespitose, 8–40 cm ×1 mm, base thickened, glabrous. Leaves: basal leaves to 13 cm; cauline leaves 1–3, mostly less than 5 cm × 5–10 mm, apex involute, glabrous. Inflorescences compact, irregular in shape; glomerules 6–10, sessile; branches few or none; proximal inflorescence bract conspicuous, leaflike, lanceolate, equal to or exceeding inflorescences; bracteoles clear, 1/2 tepal length. Flowers: tepals shining brown, with thin clear margins, 1.5–2 mm; outer and inner whorls nearly equal, (outer whorl slightly keeled); anthers longer than filaments; stigmas much longer than styles. Capsules deep purplish brown at maturity, globose (apex rounded), ± equaling tepals, apex rounded. Seeds brown, cylindric, 1.3 mm; caruncle absent.
Phenology: Flowering and fruiting summer.
Habitat: Subalpine and alpine bogs
Elevation: 3200–3700 m
