Abstract
Spreading fleabane is widely distributed throughout the western United States and northwestern Mexico (Nesom 2015) and is most widespread in the interior West (Cronquist et al. 1994). Populations occur in British Columbia and Alberta south through all states west of North Dakota and Texas. In Mexico, populations occur in Baja California, Chihuahua, Coahuila, Durango, Sonora, and likely in the more southern states (Nesom 2006). In the United States, distribution is limited at the eastern edge of its range with populations occurring only in the western parts of the Dakotas, Nebraska, Kansas, Oklahoma, and far west Texas (USDA NRCS 2024). Diploid forms of the species are scattered through at least the southern part of the species’ range (Nesom 2015).
