Abstract: Kielmeyera coriacea is one of the most characteristic entities of the Cerrado, a savanna vegetation of Central Brazil and it is a morphologically highly variable polyploid species. In the revision of the genus, an earlier variety was elevated to a related species. However, this proposal has not been accepted by the scientific community and the problematic taxonomic circumscription of the group raises doubts about various scientific studies on plants identified as K. coriacea. In the present study, we investigated the subject by a population genetics approach using eight microsatellite markers in an attempt to understand better the relationships between the proposed species. Like morphological and anatomical observations, molecular studies of highly polymorphic markers showed a great similarity between K. coriacea and K. grandiflora. However, this tool could effectively screen the boundaries of the species complex and, in addition, detect an introgressive hybridization process.
