has limited distribution in southern California, mostly along the western edge of the Mojave Desert. Stems are light brown in color, branched, and usually have a covering of short hairs. Leaves are irregularly pinnately lobed; divided almost to the midvein, and those at the base are up to 6 inches long; upper stem leaves are much shorter, and may be unlobed. Flowers are subtended by lance-shaped bracts, which may have a pair of small teeth, or lobes, near the base.
Flowers form in a small cluster at the branch tips, and they consist of five obovate, pure yellow petals, often greenish at the base, around a group of yellow stamens and styles. Petals are up to one inch in length, over twice as long as the stamens.
