Microlicieae (Melastomataceae) no município de Mucugê, Chapada Diamantina, Bahia, Brasil

Abstract

This study provides a taxonomic survey of Microlicieae tribe in the Mucugê municipality, Chapada Diamantina, Bahia, Brazil. We identified 27 species belonging to three genera: Lavoisiera (L. harleyi and L. nervulosa), Microlicia (24 species) and Trembleya parviflora. Except for Microlicia fasciculata, M. viminalis and Trembleya parviflora, the others species found in Mucugê are endemic to Chapada Diamantina, Bahia. Among the species of Microlicia, four were recently described, and four others still require further studies for its identification. Polysporangiate anthers were described for the first time for 11 species of Microlicia. The species of Microlicieae are found mainly in rocky field vegetation, between 900-1.500 m altitude, in sandy or rocky soils, sometimes associated to water streams.
