Two new species and an updated key: Melastomateae from the Serra da Canastra National Park, Minas Gerais, Brazil.

Here we describe and illustrate and two new species of the Melastomateae tribe from Serra da Canastra National Park, Minas Gerais, Brazil. We also provide an updated identification key for the members of the tribe that occur in this Protected Area. has coriaceous leaves, broadly ovate to orbicular leaf blade, entire and adpressed-strigose margin, 11-17 basal acrodromous veins, and flowers with white petals.

Chemical Composition of Extracts and Fractions from Miconia Ibaguensis (Melastomataceae) Leaves and Evaluation of Biological Activities.

The study aimed to assess the chemical composition of Miconia ibaguensis leaves extracts and fractions obtained from the ethanolic extract (EE), along with evaluating their antifungal, antibacterial, antidiabetic, and antioxidant activities. The ethyl acetate fraction (EAF) exhibited potent antifungal activity against Candida spp (1.95-3.

and (Melastomataceae), two new species from the Brazilian Cerrado.

and are described, illustrated and an updated identification key for the species of from Clube Caça e Pesca Itororó de Uberlândia is provided. occurs in Minas Gerais and Goiás States and is characterised by its linear-lanceolate and deflexed sepal on flower and immature fruit, long pedicel and indumentum of glandular trichomes, mixed with spherical, golden glands. is endemic to Uberlândia and characterised by having indumentum of setose trichomes and spherical, golden glands, magenta petal with greenish abaxial surface at the apex and dimorphic stamens with bicolorous and tetrasporangiate anthers.

Two new species of D.Don (Melastomataceae, Microlicieae) from Chapada dos Veadeiros, Goiás State, Brazil.

and , endemic to Chapada dos Veadeiros, Goiás State, Brazil, are described, illustrated and the conservation status is also provided. Both species resemble and that are also endemic to Goiás, by having sessile leaf with serrate and ciliate margin, pedicellate flower, triangular and short sepal and dimorphic stamens with bicolorous and polysporangiate anthers. However, differs by the long internode (2-4 mm long), concolorous, semi-amplexicaul and lanceolate leaf, and petal acuminate at the apex.

A new species of (Melastomataceae): first record of the genus for Colombia.

(Melastomataceae) is a Neotropical genus nearly restricted to southeastern Brazil, and the Guiana Shield in Venezuela, with a few species in some places in the Andes of Bolivia and Peru. A new species of endemic to the mountains of eastern Andes of Colombia is described and illustrated. Its affinities with other morphologically similar species from Venezuela are also documented.

Reproductive biology and species geographical distribution in the Melastomataceae: a survey based on New World taxa.

Background And Aims: Apomictic plants are less dependent on pollinator services and able to occupy more diverse habitats than sexual species. However, such assumptions are based on temperate species, and comparable evaluation for species-rich Neotropical taxa is lacking. In this context, the Melastomataceae is a predominantly Neotropical angiosperm family with many apomictic species, which is common in the Campos Rupestres, endemism-rich vegetation on rocky outcrops in central Brazil.
