| Plants loosely cespitose or short rhizomatous, with thick, dark, shallow rhizomes; culms 12–50 cm, triangular in cross section. |

1.1–3.5 mm wide; flat; evergreen; leathery; as long as or longer than the culms. |
0.6–1.8 mm wide. |
spike solitary, androgynous, lacking inflorescence bracts; male terminal portion 1–2.5 cm long, separated from the 1–3 perigynia by a short internode. |
(0.7)1–1.5(2) cm × 5–7 mm; spikes usually androgynous, or sometimes seemingly all female or all male but usually with a few, nearly undetectable flowers of the opposite sex mixed in the spikes. |
obovate, rounded at the top, 5–7(8.5) × 1.8–2.8 mm, green; whitish, or brown; beak small; stigmas 3. |

trigonous. |

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. |
Dry prairies, sagebrush steppes and open forests. 1400– 1500 m. BW, ECas. CA, ID; north to AK, east to MI, southeast to AZ; Asia, New Guinea. Native. Carex duriuscula is an inconspicuous sedge similar to C. douglasii but smaller and neater. It has been shifting its range north since the glaciers retreated. Not found in Oregon since 1940, it may be extirpated. |
