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, wet meadows, wet edges of lakes and streams. 1400–2800 m. BR, BW. CA, ID, NV, WA; north to British Columbia, east to CO. Native. Carex praeceptorum is a small, cespitose plant with brownish inflorescences with overlapping spikes. The dorsal suture of the perigynium is about as long as the beak, dark brown, and darker than the rest of the perigynium. Compare to C. canescens. |
