White Bursage, Burro Weed
Synonym: Franseria dumosa
Large parts of the Mojave and Sonoran Deserts are covered with open or very open stands of creosotebush and white bursage. The leaves of white bursage are small and deeply divided. They may become so dry that it is difficult to tell whether they are alive or dead. Like the triangle-leaf bursage, the white bursage produces a lot of pollen and has been associated with allergies.
