Stigmaphyllon mikanifolium (Malpighiaceae), a new species from Espírito Santo State, Brazil

SummaryStigmaphyllon mikanifolium is described and illustrated and its distribution, conservation status, and taxonomy are presented. S. mikanifolium can be distinguished from S. auriculatum and S. macedoanum by its leaf laminas with lobate margins, and filiform glands on the apex of each lobule, sessile discoid glands between the lobules, a petiole apex with a pair of cupulate glands, yellow posterior petals with reddish veins, and the styles parallel and straight.ResumoStigmaphyllon mikanifolium é descrito e ilustrado, e sua distribuição, status de conservação e taxonomia da espécie são apresentados.

An Unexpected Mcvaughia (Malpighiaceae) Species from Sandy Coastal Plains in Northeastern Brazil

Abstract Mcvaughia sergipana is described and illustrated. It differs from the single other species in the genus by the metallic-sericeous, and soon deciduous indumentum on the leaves, small glands scattered throughout the lamina, lateral cincinni with 1–2 flowers, and larger posterior petal. This new species is only known from sandy coastal plains in Sergipe State, Brazil, and is critically endangered. Its distribution is estimated to be less than 100 km2 in a region of extremely disturbed environments.

First records of Tovomita stergiosii Cuello (Clusiaceae: Clusieae) in Brazil

New records of Tovomita stergiosii Cuello, a species previously recorded for Peruvian and Venezuelan Amazon, are presented for Brazil. We present a distribution map, besides comments and illustration on taxonomic related species.

Taxonomic revision of Neotropical Murdannia Royle (Commelinaceae)

Abstract This study provides a taxonomic revision for the Neotropical species of the genus Murdannia. Six species are recognized as native, including a new species and a new combination, while two Asian species are recognized as invasive. We present an identification key, a table summarizing the morphologic differences among the species, a new synonym, six lectotypifications, a distribution map, and descriptions, comments and photographic plates for each species. We also provide comments on the morphology of the Neotropical species of Murdannia, comparing them with the Paleotropical species, and a discussion of inflorescence architecture in the genus as a whole.

An illustrated checklist of Malpighiaceae from the Chapada dos Veadeiros region, Goiás, Brazil

An updated checklist of Malpighiaceae from the Chapada dos Veadeiros region, Goias, Brazil, is presented. We recorded 78 species of this family of plants, which represent a higher diversity than previously reported for the region. About one third of all the Malpighiaceae species recorded for the Cerrado are found within the area, which shows the important role of the Chapada dos Veadeiros region in the conservation of this family in Central Brazil.
