Kaunia is a small genus of eleven species which play an important role in Andeanecosystems, either by dominating specific vegetation units or as subdominant species at boundaries of alder communities and ―pino del cerro‖ forests. The species of Kaunia are shrubs or small trees with commonly pinkish or white, usually tubular-funnelform corollas of internally smooth, not papillate lobes, uniformly wide styles and 20-26 chromosomes. In the frame of a lacking complete and exhaustive treatment of Kaunia, its taxonomy is herein revised. As results of this work, together with those of previous statistical studies, ten species of Kaunia are recognized. Kaunia ignorata is placed under synonymy of K. camataquiensis and a lectotype for Eupatorium hosanense is designated. Our studyprovides the first morphological and anatomical studies of Kaunia. A key to the species, detailed descriptions, illustrations and distribution maps for each species are also provided.
