The jabuticaba tree is considered one of the most typical Brazilian fruit trees. However, few studies of this plant are found in the literature and even its botanical classification is very controversial. The present research reports some comparisons between jabuticaba species, using morphologic (organography) and molecular markers techniques. The morphologic characteristics of the plant used as markers were compared with specimens of the herbaria from São Paulo and Minas Gerais States and with the descriptions reported in the literature. Molecular differences between the species were identified by the use of RAPD markers. The experiment was made in Piracicaba, Jaboticabal and Ituverava municipal districts in São Paulo State, Brazil. Morphologic and molecular differences between the studied plants were identified and four groups of species were defined: Myrciaria cauliflora (Mart.) O. Berg, M. coronata Mattos, M. jaboticaba (Vell.) O. Berg. and Myrciaria phytrantha (Kiaersk.) Mattos. Both molecular and morphologic markers techniques showed to be important tools for the identification of jabuticaba tree species.
