Encelia farinosa (commonly known as brittlebush or brittlebrush), is a common desert shrub of northern Mexico (Baja California, Baja California Sur, Sonora, Sinaloa, and Hidalgo) and the southwestern United States (California, Arizona, Utah, and Nevada). The common name "brittlebush" comes from the brittleness of its stems. Other names include hierba del vaso (Spanish) and cotx (Seri). Another Spanish name for it is incienso because the dried sap was burned by early Spanish missions in the New World as incense.
