The base chromosome number is x=10, which distinguishes it in part from the morphologically similar Brickellia. The genus is endemic to Mexico. TaxonomyThe genus was originally described by King and Robinson[1] as part of the splitting of Eupatorium into monophyletic units. The distinctiveness and circumscription of the genus were recently assessed using molecular phylogenetic approaches [4][5] Species[6][7]
