Steviopsis is a genus of Mexican plants in the boneset tribe within the sunflower family.^[2]^[3]^[4]

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]
