Montane marshes, streamsides, wet meadows, bogs. 1100–2800 m. BR, BW, Casc. CA, ID, NV, WA; north to British Columbia, east to CO. Native. This “ball-headed” sedge has a dark, compact, often pyramidal inflorescence and wingless perigynia. It looks like a young or depauperate C. microptera, but it lacks perigynium wings and grows in wetter habitats. |
Seasonally moist scablands, open conifer forest, and ephemeral watercourses. 1800–1900 m. ECas. CA, WA. Native. Carex davyi is a rare sedge with large perigynia and female scales that reveal most of the perigynium beak. Carex petasata, a widespread species of sagebrush steppe, has similar large perigynia, but its female scales are nearly as long as the perigynia, concealing most of the beak, and have wide white margins (0.2–0.7 mm wide). |
