Vernacular names
English: Brickellbush

Asanthus is a small genus of flowering plants in the daisy family, found only in northern Mexico and the southwestern United States.[1][2][3]

Each of the species was originally named as a member of Brickellia, and later transferred when King and Robinson named the genus.[4] Asanthus and Brickellia both have cypsela (achenes) with 10 ribs, but in Asanthus the style is glabrous and narrow at the base whereas in Brickellia the style has a pubescent, enlarged base. Molecular phylogenetic analysis has provided support that the two genera represent phylogenetically distinct lineages and thus should be recognized as distinct.[5]

The genus is named for American botanist Asa Gray, 1810–1888. His name is added to the Greek word "anthos" meaning "flower."[6]
