Composição florística de dois remanescentes de Mata Atlântica do sudeste de Minas Gerais, Brasil

Abstract

(Floristic composition of two remnants of Atlantic forest in the Southeastern Minas Gerais State, Brazil). This study have revised collections deposited in the BHCB Herbarium from two Atlantic forest fragments in Minas Gerais State, the Biological Station of Caratinga (EBC), in the municipality of Caratinga, and the State Park of Rio Doce (PERD), among the municipalities of Marliéria, Timóteo and Dionísio. 3366 samples of 1048 species were found, grouped in 538 genera and 123 families. In the EBC there are 513 species not occurring in PERD, where there are 242 species not occurring in EBC; 293 species are common to the two areas, with a similarity coefficient of 64%. The five families with highest number of species were Leguminosae (125), Rubiaceae (69), Asteraceae (51), Bignoniaceae (49), and Myrtaceae (39). The number of species from these fragments of Atlantic forest is higher to other recorded numbers from surveys from other Atlantic forests or the Amazonian basin.
