Leaves of hazardia whitneyi, or adeia whitneyi, are quite distinctive, being holly-shaped in outline; oblong to broadly oblanceolate, lined by sharp, well separated teeth. Leaf surfaces are rough in texture, tapering at the base, and glandular towards the tips. Leaves are stemless.
Flowerheads are single, held in open clusters on thick stalks. The bell-shaped involucre is lined by glandular, lanceolate, pointed-tipped phyllaries, often recurved. The narrow yellow ray florets number zero (var discoidea, in Oregon and northern California) or from five to 18 (var whitneyi, in the Sierra Nevada). There are between 15 and 30 orange-yellow disc florets, the corollas around a third of an inch long, slightly shorter than the ray corollas.
