A low growing, yellow-flowered annual plant. It is native to the desert and scrub habitat of the region where Arizona, California, and Nevada meet. It is a roughly hairy annual herb growing in a low patch on the ground, sometimes producing an erect stem from the basal rosette. The herbage is gray-green to reddish green. The leaves are lance-shaped and up to 3 centimeters long. The nodding inflorescence produces flowers with yellow petals 2 to 13 millimeters long, each with small red markings near the bases.
