PRAXELIS CLEMATIDEA (ASTERACEAE, EUPATORIEAE, PRAXELINAE) IN URUGUAY: FIRST RECORD OF THE GENUS AND THE SPECIES.

During the revision of the southern South American species of Praxelis, populations of P. clematidea were found in northwestern Uruguay. In this study, we provide the first record of the genus and the species for the Uruguayan flora, along with taxonomic and morphological analyses based on herbarium specimens and field observations. In addition, uses of P. clematidea, its distribution and habitat, common names, an illustration and a key to differentiate the species of Praxelis of Uruguay and surrounding areas of Argentina and Brazil are presented.
