| Plants cespitose, 9–40 cm tall. |
1.5– 4 mm wide. |
1.1–2.1 cm × 13–18 mm; dense and head-like, with a fine texture because the perigynia are many and thin, not spreading; spikes gynaecandrous. |
flat except over the achene, 4–6.5 × 1.5– 2.6 mm; light to dark brown (occasionally greenish) with dark to black tips, with several light dorsal veins and 0–3(8) ventral veins; wings 0.3–0.6(0.8) mm wide; beak tip unwinged, brown; and parallel-sided for at least the distal 1 mm; entire for the distal 0.3–0.6 mm; (2.3)2.6–3.8 mm from achene top to beak tip; stigmas 2. |
lenticular; (1.2)1.4–1.8 × 0.8–1.1(1.3) mm, 0.3–0.5 mm thick. |
3–4.8 mm long; shorter and narrower than the perigynia, generally brown or purplish, sometimes with a paler mid-stripe. |

Moist or mesic, gravelly or rocky, subalpine or alpine slopes and flats, often in snowmelt zones. 1500–3100 m. BR, BW. CA, ID, WA; north to British Columbia, east to CO, southeast to NM. Native. This “ball-headed” sedge grows near or usually above timberline. Its dense, black or blackish green heads resemble those of C. microptera, a close relative with shorter perigynia that grows at lower elevations. |
