Abstract

Pleroma barbellatum P.J.F.Guim., D.Nunes & I.M.Araújo a new species of Melastomataceae (Melastomateae) from the Espinhaço Range of Minas Gerais State, Brazil, is described and illustrated, and their affinities and diagnostic characters are here discussed. Pleroma barbellatum is closely related to P. formosum, P. martiale, and P. riedelianum. They share a similar habit and leaves that are alike in size and shape. However, they can be distinguished by differences in the trichomes of the branches, leaves and inflorescences, in addition to other characters related to the type of inflorescence and size of the bracteoles. We recommend a conservation status of Endangered for P. barbellatum.
