Melastomataceae from the “Parque Estadual do Guartelá”, Tibagi, Paraná, Brazil: species list and field guide

We studied an area with “Cerrado” associated to other vegetation types at the “Parque Estadual do Guartelá”, Tibagi, in the state of Paraná, Brazil. Herein, we have a list with all species of Melastomataceae recorded in the area with an illustrated guide including all of them. Despite the small area of this Conservation Unit, the park hosts a large number of species (36), in the following genera: Acisanthera, Chaetostoma, Lavoisiera, Leandra, Miconia, Tibouchina and Trembleya. The region where the park is located is considered the southern limit of the “Cerrado” biome, and also the limit of distribution of many Melastomataceae species. The distribution of the Melastomataceae species along the different vegetation types in the PEG seems to be a pattern for the family in general, registered also for other areas of “Cerrado” in Brazil
