A revision and a morphological analysis of the Uruguayan species of Stevia (Compositae, Eupatorieae) were performed. Leaf, inflorescence, pubescence and pappus traits were identified as key to separate species. Stevia entreriensis, S. entreriensis var. minor, and Dissothrix hassleriana were considered synonymys of S. hirsuta, and S. opryodonta a synonym of S. veronicae. A lectotype for the name Stevia veronicae was designated. Stevia burkartii was excluded from the Uruguayan flora. As a result, 10 Uruguayan species of Stevia are considered: S. aristata, S. cinerascens, S. congesta, S. gratioloides, S. hirsuta, S. multiaristata, S. sabulonis, S. satureiifolia, S. selloi, and S. veronicae. A key to the Uruguayan species, descriptions, photographs and distribution maps are provided.
