Packera breweri
Packera cana
Packera breweri is known only from Coast Ranges from San Francisco Bay to Los Angeles County and along the eastern edges of the San Joaquin Valley. Populations are relatively small and sporadic; the plants appear not to hybridize with other species of Packera.

Packera cana is found in a wide variety of habitats and in a wide range of elevations throughout the western Cordillera and into the High Plains. Morphology is relatively uniform throughout its range except that alpine specimens are notably dwarfed and are often mistaken for P. werneriifolia, which differs by its consistently scapiform habit.
