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). |
