Notes: FNA23: "Carex tahoensis resembles C. phaeocephala somewhat, but often occurs at lower elevations, has longer achenes, and more coriaceous perigynia that are clearly veined adaxially.
Carex tahoensis was orginally described as a California endemic, but is much more widespread. The precise distribution is as yet unclear because of confusion with C. phaeocephala and C. petasata. Many reports of C. xerantica from the Rocky Mountain region are based on this species."
