plant bases whitish or pale to medium brown; lower sheaths usually with blades; blades 1–3.5 mm wide, glaucous, channeled. |
spike solitary, androgynous, lacking inflorescence bracts; male terminal portion 1–2.5 cm long, separated from the 1–3 perigynia by a short internode. |
lateral spikes usually 1–2; female, 0.7–2.5 cm × 4–5.5 mm; terminal spike male, 1–3.3 cm × 1.4–5 mm, with 16–100 flowers. |

Well-drained soils in dry, open, conifer forests, aspen stands, and openings, rarely in sagebrush, on both serpentine and nonserpentine substrates. 100–2500 m. BR, BW, Col, ECas, Lava, Owy, Sisk. CA, ID, NV, WA; north to southeastern British Columbia, east to CO, PA. Native. Carex geyeri is a common ground cover in open forest, especially in northeastern Oregon, recognized by its tough, flat, evergreen leaves from dark, scaly rhizomes. Similar pinegrass, Calamagrostis rubescens, usually has hairy internodes and when in flower it is easily distinguished. Carex geyeri is important food for wildlife and livestock, especially in winter. In southwestern Oregon, C. geyeri can be confused with C. multicaulis, which is densely cespitose and has proportionately shorter, usually involute leaves, and longer, green, leaf-like, lower female scales. |
Bogs and fens with the water table at or close to the surface, usually with extensive peat deposits but sometimes on mineral substrates next to slow streams. 100–1400 m. Casc, Est. CA, WA; north to AK, east to Newfoundland, IL, NJ; South America; Eurasia, Panama. Native. From a distance, the grayish color of C. livida can give a bog a moldy appearance. This is a glaucous, narrow-leaved, rhizomatous sedge with pale, papillose, spindle-shaped perigynia. Similar C. klamathensis, of serpentine fens, has broader leaves and obovate perigynia with the apex usually bent to the dorsal side. |
