The objective of this work was to carry out the floristic survey of phanerophytes along a gradient of "cerrado sensu stricto " and "cerradão" in an area of 2,600m² in the FLONA (Floesta Nacional - National Forest) of Paraopeba, MG, Brazil. A total of 91 species pertaining to 71 genera and 41 families were found. The most representative families were Leguminosae, Myrtaceae, Malpighiaceae, Vochysiaceae, Rubiaceae and Melastomataceae. Miconia, Myrcia, Erythroxylum and Qualea were the richest genera. Magonia pubescens was outstanding in number of individuals. The floristic similarity showed the separation of the plots in two groups, the first one showed a similarity level around 45%, and the second group was divided into two large groups, the first one showed a similarity level around 38% and the remaining plots did not form definite groups. The species ordination by canonical correspondence analysis suggests that Magonia pubescens, Bauhinia holophylla and Terminalia brasiliensis tended to be most abundant species in areas with higher values of pH, Mg, H+Al. The non-explained variation for the other species could be associated to other non-analyzed variables as well as to a complex set of factors that are involved in the vegetation composition determination.
