The main distinguishing characteristic of chrysothamnus depressus is its long, narrow involucre - up to 0.6 inches in length and less than 0.2 inches in width. This species is found mostly on the Colorado Plateau, extending to mountainous regions of the Mojave Desert.
Leaves are short, narrow, upwards pointing, held close to the stem. They, and the stems, may have a sparse covering of short, rough hairs, or be essentially hairless. Flowerheads are formed in small, tight clusters; they contain five or six disc florets, with spreading, sharply-pointed lobes and protruding, branched styles. Phyllaries are narrow, ribbed and pointed, often purplish; they are arranged in four to six rows and five vertical ranks, sometimes slightly spiral.
