Background and aims: The taxonomic location of the Potentilleae tribe speciesin Argentina was highly controversial and intensely debated by various authors,in such a way that some merged genera, while others recognized them as validtaxonomic entities. These conflicts show the need for an updated taxonomictreatment. The objective of this work is to present an updated taxonomic synopsisof the Potentilleae in Argentina.M&M: Taxonomic data from the literature were collected, including phylogeneticstudies, and specimens of the Potentilleae tribe of Argentine and foreign herbariawere analyzed; in addition to material collected in the field.Results and Conclusions: In Argentina, 3 genera with 5 species and 2 forms wererecognized for the Potentilleae tribe, differing in a dichotomous key by vegetative,floral and carpological characters. The name of the authors of a species waslegitimized and a form was lectotypified. The distribution of one species wasbroadened and the presence of another was rectified. The Potentilleae inhabit trails,pastures, herbaceous stratum of the Yungas, in open spaces and at elevationsfrom 600-2600 meters above sea level. They grow in riparian environments and inabandoned crops.
