This blooming California Brickellbush, Brickellia californica, was in Ready Pay Gulch (Pink Canyon) east of Hillsboro, New Mexico in late September of 2014. It has a range which extends through most of the western United States (being absent in Oregon, Washington, and Montana) as well as Oklahoma, Texas, and Baja California. A description of the species can be found at Flora of North America.
This species was first described as Bulbostylis californica by John Torrey & Asa Gray, in Flora of North America, Part 2, page 79, in 1841. In their original description they raised the possibility that it was "perhaps not sufficiently distinct from Brickellia".
A cold infusion of the leaves of this plant was taken by the Navajo for colds and fever.
