Culms 35–90 cm, scabrous on angles. Leaves: proximal sheaths red-brown, fronts with (red) pale brown spots, prominently ladder-fibrillose, bladeless, glabrous, backs scabrous; leaf blades 3–6 mm wide. Perigynia ellipsoid to obovoid, apex acute. 2n = 74.
Phenology: Fruiting Jul–Aug.
Habitat: Wet subalpine meadows
Elevation: 1000–1400 m

Discussion
Carex scopulorum var. prionophylla usually occurs at somewhat lower elevations than var. bracteosa. Where the two are sympatric, they can be distinguished by the bladeless, ladder-fibrillose basal sheaths and the narrower ellipsoid perigynia of var. prionophylla.
