ABSTRACT
Myrtaceae is a pantropical family with around 5500 species and 132 genera and is highlighted by its complex (cryptic characters) and difficult taxonomy. In Brazil, Myrtaceae is represented by 23 genera and 974 species and is one of the most representative in the Espinhaço Range. The main goal of this work was the floristic survey of Myrtaceae in Jacobina, Chapada Diamantina, Bahia. Five expeditions were conducted between June/2011 and April/2012; herbaria materials were examined in the State; and specialized references and Myrtaceae experts were consulted. Seven genera and 32 species of Myrtaceae were found andMyrcia DC. (14 spp.), Eugenia L. (nove spp.), and Psidium L. (quatro spp.) were the most representative, corresponding to 87% of total species. Myrcia blanchetiana (O. Berg) and Mattos is endemic to Bahia, two species (Eugenia rostrata O. Berg and Psidium brownianum DC.) are new occurrence to Jacobina and a new species ofMyrcia has been recognized. Generic and specific keys are presented, as well as discussion about the morphology and geographical distribution of the taxa.
