''Asanthus'' is a small genus of flowering plants in the daisy family, found only in northern Mexico and the southwestern United States.〔〔 D.J.N.Hind & H.E.Robinson. 2007. Tribe Eupatorieae In: ''The Families and Genera of Vascular Plants'' vol.VIII. (Joachim W.Kadereit & Charles Jeffrey, volume editors. Klaus Kubitzky, general editor). Springer-Verlag. Berlin, Heidelberg. 〕〔(Tropicos, ''Asanthus'' R.M. King & H. Rob. )〕 Each of the species was originally named as a member of ''Brickellia'', and later transferred when King and Robinson named the genus. 〔 R. M. King & H. Robinson. Phytologia 24(2): 66. 1972.〕 ''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. 〔 Schilling, E. E., J. L. Panero, B. S. Crozier & P. Davila. 2013. Relationships of ''Asanthus'' (Asteraceae, Eupatorieae). Systematic Botany 38: 253-258.〕 The genus is named for American botanist Asa Gray, 1810–1888. His name is added to the Greek word "anthos" meaning "flower."〔(Flora of North America, ''Asanthus'' R. M. King & H.
