Subspecies parishii is found in coastal ranges in southern California and Baja California, and inland to areas south of the Great Basin. It has been distinguished traditionally by the presence of drooping flowering branches and hairy cypselae, characteristics found on the type specimen. These characteristics occur sporadically in populations of other subspecies throughout the warm desert regions of southern California, Nevada, and Utah; the characteristically longer leaves and distinctive aroma support recognition of this subspecies. This treatment is the first to include Mojave Desert, Owens Valley, and Colorado Plateau populations within subsp. parishii.
