It is endemic to California in the United States, where it is known only from Kern County. It grows along a 21-mile stretch of the Kern River. Heterotheca shevockii is a perennial herb growing 28 to 131 centimeters (11. 2-52. 4 inches) in height, often with many erect stems. The stems are hairy to bristly. The lance-shaped leaves are up to 6. 5 centimeters (2. 6 inches) long by 1. 6 cm (0. 64 inches) wide. The inflorescence contains 3-70 flower heads borne on hairy, glandular peduncles. Each head contains up to 18 yellow ray florets each up to a centimeter long, and many disc florets at the center. The fruit is an achene which may be over a centimeter (>0. 4 inches) long including its pappus. Flowering occurs mostly in August and September, but it may be seen in flower between January and November.
