|Descrição:||In this study 26 distributed fragments of native forest in four located hydrographical Basins in the northeast region of Minas Gerais had been showed, with the purpose of analyzing the floristic similarity exists between 26 forest fragments native inserted in four basins in the northeast of the state of Minas Gerais and the diversity and evenness of physiognomies studied and groups of fragments formed. Systematic sampling with units was used shows of 1000 m² each, where the sample area varied of 1 the 6 has, as the area I break up of it. We measured the circumference at 1.30m (CAP) and the total height and collected botanical material of all individuals with CAP greater or equal to 15.7 cm. Six groups were formed according to the floristic similarity coefficient Sorensen, with four groups there was an association of more than a physiognomy, showing regions of transition within the area. The Shannon diversity index, ranged from 2.236 in deciduous forest to 4.523 in Semideciduous Forest. The maximum and minimum values of evenness index Pielou were 0.850 and 0.616 , respectively. The floristic group 2 (Semideciduous Forest and Cerrado sensu stricto) had the highest average value of diversity (3.585 ) and evenness (0.750 ), and group 1 (Deciduous Forest) had the lowest values (H’: 2.426 and J’: 0.687 ).|
