About plant names...

Cheesebush is native to the Sonoran, Mojave, and Colorado Deserts of Baja California, southern California, southern Nevada, the southwestern corner of Utah, Arizona, and northwest Mexico. The name comes from a disagreeable cheeselike odor given off when the leaves are crushed.

Identification: Cheesebush is a rounded, often disheveled shrub 3-8' (91-243 cm) in height and 6-24' (1.8-7.3 m) around. It is a perennial, but it drops its leaves during periods of drought. It has thin branches and needle-like leaves ¾-3" (1.9-7.6 cm) long, but only ¹/₃₂-¹/₁₆" (1-2 mm) wide. It has multiple white male flowers about ¼" (8.3 mm) in diameter. It is an early colonizer of disturbed sites, being replaced in time by plants such as creosotebush.
