It grows throughout Southern California to Texas and Mexico.[2] In the Mojave Desert, it grows in creosote bush scrub and Joshua tree woodlands.[2]
Growth pattern
It is a hairy, erect, annual plant growing between 2" and 12" tall.[2]

Its 1/2- to 3/4-inch-long leaves are attached to the stems without a little stem (petiole) at the bottom of the leaf (sessile).[2]
