Notes: FNA23: "Carex exsiccata is regarded by some authors, with some justification, as C. vesicaria var. major. It is a coarser plant with leathery, lanceolate perigynia gradually tapered to the apex that occurs at lower elevations and is usually readily distinguishable although some plants from the Cascades are difficult to place. In the west, typical C. vesicaria occurs mostly above 1400 m. Some authors (B. Boivin 1967–1979; T. M. C. Taylor 1983) treat all western plants as C. exsiccata, distinct from the eastern North American and Eurasian C. vesicaria. The Rocky Mountain, Cascade Range, and Sierra Nevada plants do not differ substantially from eastern plants, except that sometimes they have darker perigynia and scales."
