A systematic revision including the geographic distribution of the taxa pertaining to the Chilean Mutisioideae (tribes Mutisieae, Nassauvieae and Onoserideae) has been undertaken. The study has been done by means of the revision of available monographs and the most recent regional checklist, together with the examination of exemplars from SGO and CONC herbaria. Results show the presence of 28 genera, 192 species, and 22 other infraspecific taxa in Chile. Seven of these genera, 77 species, and 12 infraspecific taxa are endemic to the country. The revision suggests two additions and two subtractions from the Chilean flora. Furthermore, the geographic distribution in Chilean regions of 47 taxa was corrected. Finally, the implications of an adequate geographic knowledge of these species are discussed, in relationship to the biogeography and the conservation of the Chilean flora.
