A tribo Miconieae no Parque Estadual do Biribiri está representada por 23 espécies e cinco gêneros. Miconia é o gênero mais numeroso, com 14 espécies, seguido de Leandra com quatro, Clidemia com três e Tococa e Ossaea com uma espécie cada. As espécies ocorrem na maioria das fitofisionomias do parque, com um maior número de espécies nas formações florestais. Chave de identificação para as espécies, descrições e dados de distribuição geográfica são fornecidos, assim como ilustrações dos táxons pouco representados na literatura. Palavras-chave: Clidemia, Leandra, Miconia, Ossaea, Serra do Espinhaço, Tococa.
AbstractThe Miconieae tribe is represented by 23 species and five genera in the Parque Estadual do Biribiri. Miconia is the largest genus, with 14 species, followed by Leandra with four, Clidemia with three, Tococa and Ossaea with one species each. Species occur in almost vegetation types in the park, with a larger number of species occurring in forests. Identification key for the species, descriptions, and geographic distribution data are provided, as well as illustrations for the taxon poorly illustrated in the literature.
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.
