Steviopsis
Introduction '''''Steviopsis''''' is a genus of Mexican plants in the tribe Eupatorieae within the family Asteraceae.
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 as part of the splitting of ''Eupatorium'' into monophyletic units. The distinctiveness and circumscription of the genus were recently assessed using molecular phylogenetic approaches : Species* ''Steviopsis amblyolepis'' (B.L.Rob.) R.M.King & H.Rob. - Guerrero, Morelos, Michoacán* ''Steviopsis arsenei'' R.M.King & H.Rob. - Michoacán* ''Steviopsis dryophila'' (B.L.Rob.) B.L.Turner - Jalisco, Nayarit, Zacatecas, Sinaloa* ''Steviopsis nesomii'' B.L.Turner - Nuevo León* ''Steviopsis rapunculoides'' (DC.) R.M.King & H.Rob. - Jalisco, Guanajuato, Nayarit, Morelos, Michoacán* ''Steviopsis vigintiseta'' (DC.) R.M.King & H.Rob. - Oaxaca, Puebla, Morelos, México State; formerly includedsee ''Asanthus Brickelliastrum Dyscritogyne''
