Dauresia flava B. Nord. is described from southern Namibia as new to science. The two species of Dauresia are allopatric, D. alliariifolia being distributed in northern and central Namibia, whereas D. flava is restricted to the southernmost area close to the Orange River and belongs to the Gariep floristic element. The new species differs inter alia by the yellow floret colour, smaller few-dentate leaves, and lack of woolly indumentum in the leaf-axils.
