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.
