The tribe Mutisieae sensu lato (Asteraceae), with 85 genera and ca. 960, species is extremely diverse morphologically. Its basal position enhances the tribes´s value as a key for understanding the systematics, evolution, and biogeography of the whole family. Since the elevation of Barnadesiinae to subfamily status, the Mutisieae became constituted by three subtribes: Mutisiinae, Gochnatiinae, and Nassauviinae; then the fist two were joined in  Mutisiinae sensu lato. Nassauviinae is monophyletic but Mutisiinae is taxonomically complex, constituted by generic groups, isolated genera, and taxa of dubious position. Molecular phylogenies exclude Ainsliaea and relatives, Dicoma and relatives, Gochnatia and relatives, Brachylaena and Tarchonanthus, Hesperomannia, Oldenburgia, and Hecastocleis, but a final resolution of the tribe taxonomy has not been achieved. The last morphological studies of  Mutisieae agree with the exclusion of  many of these taxa, but not with the exclusion of Gochnatia and relatives, Ainsliaea and relatives, Oldenburgia, and  Hecastocleis. The value of the style and pollen morphology  in the classification of Mutisieae is emphasized.
