Euthamia

Euthamia is a genus of flowering plants in the aster family, Asteraceae. They are known commonly as goldentops and grass-leaved goldenrods. The species were formerly classed in genus Solidago, the goldenrods. They were separated on the basis of morphological differences, such as the arrangement of the flower heads in the inflorescence and the glands on the leaves, and of DNA data. Authors have recognized 5 to 10 species. They are native to North America, but certain species are introduced in Europe and Asia.
