Summary
Microlicia D.Don is a predominantly Brazilian genus composed of ca. 240 species (Versiane et al 2021), with most species occurring in the campo rupestre from Minas Gerais, Bahia and Goiás States (Romero 2003a, b; Romero et al 2020) and about 49 species occurring in the cerrado phytophysiognomy. Its central portion has an important fragment of vegetation inside a private club, the Clube Caça e Pesca Itororó de Uberlândia, in Uberlândia Municipality This area has 127 hectares of well-preserved vegetation composed of cerrado, campo sujo, vereda, forest (Apolinário and Schiavini 2002) and a considerable area of campo úmido and campo limpo (Bacci et al 2016). The inventory of the Melastomataceae from Clube Caça e Pesca Itororó de Uberlândia catalogued 28 species (Bacci et al 2016); the authors were unable to fit some collections of Microlicia under any of the existing names in the genus. The identification key for the species of Microlicia in the Clube Caça e Pesca Itororó de Uberlândia is updated
