E apresentado o tratamento taxonomico para os generos Aciotis , Acisanthera , Marcetia e Pterolepis . (Melastomeae, Melastomataceae) no estado do Rio de Janeiro. Cada um dos quatro generos apresentados esta representado por uma unica especie no estado: Aciotis paludosa , Acisanthera variabilis , Marcetia taxifolia e Pterolepis glomerata . Com este estudo se atualizou a lista de especies para a flora do estado do Rio de Janeiro, removendo seis especies equivocadamente listadas. Um tratamento…

A new species of Pleroma (Melastomataceae, Melastomeae) from southeastern Brazil

Towards a new understanding of the division of labour in heterantherous flowers: the case of Pterolepis glomerata (Melastomataceae)
TLDR
This work presents a new strategy based on a high investment in reward production and thus attraction, in the heterantherous Pterolepis glomerata to overcome short flower longevity and maintain reproductive success and demonstrates that the division of labour might have different outcomes.

Three new Brazilian species in the genus Marcetia (Melastomataceae, Melastomeae)
TLDR
The new species Marcetia shepherdii and M. lychnophoroides, together with M. luetzelburgii Markgraf, constitute a group of closely related species that are endemic to Bahia.
Taxonomic Novelty and Typifications in Microlepis (Melastomataceae)
TLDR
Molecular phylogenetic studies in the Melastomeae indicate that Microlepis is nested within Pleroma D. Don, and therefore the new combination is provided as P. oleifolia (DC.) R. Romero & Versiane.
A revision of Pterolepis (Melastomataceae: Melastomeae)
TLDR
The main diagnostic feature of the genus are branched emergences in the intercalycine sinuses but these are variable among the species and also occur in many paleotropical and two neotropical species, casting some doubt on their taxonomic value above the species level.
Taxonomia de Melastomataceae no Brasil: retrospectiva, perspectivas e chave de identificação para os gêneros
TLDR
A historical framework on the study of Melastomataceae taxonomy in Brazil is presented, as well as an identification key for the genera occurring in Brazil and perspectives for future studies are discussed.
Henrietteeae (Melastomataceae): A New Neotropical Berry-Fruited Tribe
TLDR
Based upon a series of presumably synapomorphic anatomical and morphological characters, e.g. megastyloid crystals, absence of both medullary and cortical vascular bundles, plinerved leaves, axillary or cauliflorous inflorescences, three additional genera are considered to belong to this clade, a newly recognized tribe, Henrietteeae, which is neither nested within nor sister to the Miconieae.
Molecular phylogenetics of Melastomataceae and Memecylaceae: implications for character evolution.
TLDR
Parsimony and ML analyses of cpDNA sequences from the rbcL and ndhF genes and the rpl16 intron generate congruent topologies that place Memecylaceae as sister to Melastomataceae, implying, for example, that berries evolved from capsules minimally four times, stamen connectives went from dorsally enlarged to basal/ventrally enlarged, and loss of an endothecium preceded poricidal dehiscence.
