Psilostrophe cooperi is a flowering plant in the daisy family known by the common names Cooper's paper daisy and whitestem paperflower. It is native to the Mojave and Sonoran Deserts of California , the Southwestern United States, and northwestern Mexico.
Description
P. cooperi is perennial shrub with stems rising from a woody base to form that a nearly spherical form.[1] It is a low, spreading bush with pale green, hairy foliage. It is drought deciduous, dropping its leaves in times of drought.[1] The linear leaves are alternate.[1]
The daisylike flower heads have 3 to 8 deeply toothed golden-yellow ray florets. The flower heads are often bunched together at the tops of the stems in a rounded spray. The ray flowers persist for a time and then dry and become papery while maintaining their yellow color. The 3 toothed corollas of the dried ray flowers fold back over the phyllaries.[1]
Several related species are poisonous to livestock.[2]
