Resumen

Pleroma eglanduliferum, Justino & P.J.F. Guim. sp. nov. a new species of Melastomataceae (Melastomateae) from the Atlantic Forest of Minas Gerais State, Brazil, is described and illustrated, with their affinities and diagnostic characters discussed. Pleroma eglanduliferum is closely related to P. heteromallum (D. Don) D. Don and P. tedescoi Meirelles, L. Kollmann & R. Goldenb.) P.J.F . Guim. & Michelang. by plant architecture, with quadrangular branches and similar leaf in shape and indument. However, they can be distinguished by the variation in the stamens morphology and sizes of bracteoles. Pleroma eglanduliferum must be included in Critically Endangered category, since it is known only from one population, in a restricted area.
