Notes: FNA23: "Carex nebrascensis is a common low- to mid-elevation western species that is morphologically somewhat similar to C. aquatilis; it differs in the obovoid, distended, veined perigynia with a bidentate beak and the awned scales. The amphistomatous leaves of the species are glabrous and often glaucous even when mature. Cattle frequently graze on C. nebrascensis."
