Resumo

During the study of Brazilian genera of the Inuleae-Plucheinae (Asteraceae), we have encountered a specimen representing an undescribed species, here described as Tessaria andina. The new species is characterized by having puberulous, tomentose, lanate, or glabrescent indumentum on its branches, a tomentose abaxial leaf surface, leaves with an apically serrate margin, corymbiform inflorescences, a cream to yellowish involucre, erect inner involucral bracts, and the corolla of male flowers with short-stalked glands and trichomes. So far, only one collection of this new species has been made, and that was more than forty years ago. The new species is described, illustrated, and its affinities are discussed. Furthermore, during this investigation we found out that the name Tessaria boliviensis is a nomen nudum, applied to material here shown to belong to Tessaria fastigiata. An identification key to the species of Tessaria is also presented. (AU)
