Abstract: This study deals with the geographical distribution of Eupatorieae species in South-eastern and Southern Brazilian mountain ranges, with special emphasis on the Mantiqueira range (Serra da Mantiqueira). In the Mantiqueira range, five localities were sampled for two years during the flowering period of the plants. Species composition in the Mantiqueira localities was then compared to data from a central range (the Espinhaqo) and a southern coastal range. Cluster and ordination analyses showed clear floristic differences among the three ranges. Nearer localities were more similar floristically only within the Espinhaqo range and across all ranges, as shown by Mantel tests. The dendrogram in the Mantiqueira range clustered Itatiaia and Campos do Jordao, two non-adjacent localities with similar environment, landscape and topography. Different processes may be influencing the structure and composition of the Eupatorieae flora at different geographical scales. Historical and biogeographical processes may be more important in determining community composition of different mountain ranges, whereas factors such as climate and human impact may be determining differences among localities within each mountain range.
