Brickellia lemmonii (Lemmon's brickellbush) is a North American species of flowering plants in the daisy family. It is native to northeastern and north-central Mexico (Chihuahua, Coahuila) and the southwestern United States (southern New Mexico, southeastern Arizona, western Texas). Brickellia lemmonii is a shrub up to 50 cm (20 inches) tall. It produces many small flower heads with pale yellow-green disc florets but no ray florets. The species is named for John Gill Lemmon (1831–1908), husband of American botanist Sara Plummer Lemmon (1836–1923).
