Brickelliastrum
Introduction '''''Brickelliastrum''''' is a North American genus of flowering plants in the tribe Eupatorieae within the family Asteraceae. ''Brickelliastrum'' has at times been lumped with ''Brickellia'' or ''Steviopsis'', but chromosome number (''x''=10) and molecular data are in agreement in showing that it is distinct from either of these. Despite having the general appearance of ''Brickellia'', members of ''Brickelliastrum'' have cypselae that have only 5-7 ribs (vs. 10), funnel-shaped corollas, and a style with an unenlarged, glabrous base.There is only one recognized species, '''''Brickelliastrum fendleri'''''. It is native to the southwestern United States (Arizona, New Mexico, and western Texas) and northern Mexico (Coahuila). ;formerly included* ''Brickelliastrum nesomii'' (B.L.Turner) R.M.King & H.Rob., see ''Steviopsis nesomii'' B.L.Turner* ''Brickelliastrum villarrealii'' R.M.King & H.Rob., see ''Steviopsis nesomii'' B.L.Turner
