| Plants loosely cespitose or short rhizomatous, with thick, dark, shallow rhizomes; culms 12–50 cm, triangular in cross section. |
Plants cespitose or short rhizomatous, 10–95 cm tall. |
1.1–3.5 mm wide; flat; evergreen; leathery; as long as or longer than the culms. |
1–2.4(2.7) 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. |
spikes separated, usually gynaecandrous, sometimes female, with perigynia widely spreading or reflexed at maturity; lateral spikes 3–9.5 mm long; terminal spikes 5.2–20 mm long, with a narrow 2.2–14.5 mm long male portion. |
obovate, rounded at the top, 5–7(8.5) × 1.8–2.8 mm, green; whitish, or brown; beak small; stigmas 3. |
1.9–3(3.3) mm long; reddish brown to dark brown, sometimes green, usually veinless on the ventral surface over the achene; base somewhat swollen; pithy when mature; beak 0.4–0.9 mm long, 20–40(43)% of perigynium length; margins usually serrulate; stigmas 2. |
trigonous. |
lenticular. |
the lower longer than the perigynia; the upper reduced; more or less brown with paler midrib and margins, pointed to awned. |
inconspicuous; shorter than the mature achene. |

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. |
Springs, wet canyon walls and seeps. 600–2200 m. BW, Casc, ECas, Lava. CA, ID, NV, WA; north to AK, east to Newfoundland and VA, southeast to AR, AZ, and Mexico. Native. Carex interior is an inconspicuous, slender-leaved, cespitose sedge with an interrupted inflorescence, the star-like spikes with widely spreading perigynia that taper abruptly to the short beak. Carex echinata has longer, gradually tapering perigynia. In southwestern Oregon, C. interior perigynia tend to have longer beaks than is typical, more similar to those of C. echinata. |
