Notes: FNA23: "Much too broad a range has been ascribed previously to this taxon. Reports from the Rocky Mountains are based mostly on misidentifications of Carex petasata and C. tahoensis, both of which differ in having reddish brown pistillate scales and larger perigynia that are distinctly veined adaxially."
