Description

Members of Steviopsis are perennial herbs that have heads composed entirely of disk flowers, a pappus of capillary bristles, narrow corollas with spreading lobes, and glands on the cypselae (achenes). The base chromosome number is x=10, which distinguishes it in part from the morphologically similar Brickellia. The genus is endemic to Mexico.

Taxonomy

The genus was originally described by King and Robinson[2] as part of the splitting of Eupatorium into monophyletic units. The distinctiveness and circumscription of the genus were recently assessed using molecular phylogenetic approaches [5][6]
