Encelia ravenii is a multi−branched perennial shrub, reaching 1–3 feet (0.30–0.91 m) in height. The branches are lined with oval to roughly triangular leaves a few centimeters long, that are gray-green and woolly in texture.

The inflorescence is a solitary daisylike flower head 1–2 inches (2.5–5.1 cm) in diameter, on a tall, erect peduncle. The head has a center of many yellow disc florets surrounded by up to 25 white ray florets. The involucre consists of long, prominent phyllaries. It blooms in the Spring.^[1]

The fruit is an achene about half a centimeter long, usually lacking a pappus. The fruits have ciliate margins

Distribution[]

The plant is native to Baja California in México, where it is known only from one small granite hill near the Gulf Coast town of San Felipe.
