Abstract

In this study a list of species from the Melastomataceae family occurring in São José range, mostly located in Tiradentes and Prados municipalities, in the southeastern part of the state of Minas Gerais, Brazil, is presented. The samples were collected mainly in Campo rupestre and Cerrado formations. The list of genera and species found in São José range was compared with lists of Melastomataceae from some campo rupestre ranges published for Minas Gerais and Bahia states and the Guyana Shield. In this study 17 genera and 57 species of Melastomataceae were found, which is a considerable richness for an area of only 30 km². Thes following genera were registered: Miconia (15 species), Tibouchina (9), Leandra (8), Microlicia (7), Trembleya (3), Cambessedesia (2), Chaetostoma (2), Rhynchanthera (2), Acisanthera, Clidemia, Comolia, Lavoisiera, Macairea, Marcetia, Ossaea, Siphanthera, and Svitramia (one species each). Leandra australis (Cham.)Cogn., a species from Southern Brazil, was reported for the first time for the state of Minas Gerais; also, a new species of Cambessedesia was registered.
