A little herb from central Peru is recognised as a new species of a new genus. Centenaria rupacquiana belongs to the tribe Eupatorieae, subtribe Piqueriinae. It has asymmetrical corollas with two inner lobes smaller, a flat and epaleaceous receptacle and the presence of pappus. In Peru, Centenaria is related to the genera Ferreyrella and Ellenbergia, but Ferreyrella is different by having no pappus and a paleate receptacle; and on the other hand, Ellenbergia is different by having symmetrical corollas.
