The area of the extreme North of Minas, due to your character ecotone, involves a large number of physiognomies and floristic complexes, but presumably unknown. Thus, the aim of this research was to determine the structure and the floristic composition of an area of arboreal caatinga in Juvenília, Minas Gerais. Hopes to contribute with information that allow, in the future, that is arrived to a classification it aims at and coherent of this vegetation. A sample of 10 (20x20m) plots was allocated (400m2), distributed on a parallel transect to the largest axis of the fragment, and to each 20 meters in this transect two plots were allocated, distanced 10 meters to each other, totaling 0.4ha. All the individuals were registered with CBH (circumference at breast height) > 10cm. In the structure, 36 species with diversity of H' = 2.4 and eqüability of J' = 0.67 were sampled, values middlemen if compared with results of other works developed at Brazilian deciduous seasonal forests. Acacia martii, Caesalpinia pluviosa, Eugenia uniflora and Tabebuia impetiginosa presented the largest values in all the structural parameters analyzed. This links with the high abundance of those species. The community's diameter distributions tended to the normality with smaller amount of individuals in the classes smaller and larger diametric.
