|discussion=<p>Eurybia merita occurs mainly from the Interior Mountains and Plateaus system to the Rocky Mountains, and is disjunct to the Black Hills of South Dakota. It reaches California in Siskyou County; the species has been overlooked in this state (e.g., G. A. Allen 1993) because of misidentification with E. radulina. S. L. Welsh et al. (1987) reported E. sibirica from the Uinta Mountains of Utah (Summit County), which A. Cronquist (1994) attributed to var. merita.</p>
