Malpighiaceae Juss. na Serra dos Carajás, Pará, Brasil.

Abstract

The Serra dos Carajás is located in the southeastern region of the Pará state, and comprise a group of plant formations with predominantly dense ombrophilous forest and cangas areas. This group contains a diversity of native and endemic plant species that need to be studied by the science because of the intense antropic action in the region, which over the course of time has devastated the landscape in the south region of Pará state through deforestation due to the livestock production and the extraction of mineral resources, causing major environmental impacts. Malpighiaceae presents incipient studies when it comes to the Brazilian Amazon, and even less in the Pará state. In this context, this study presents the Malpighiaceae species occurring in Serra dos Carajás, Pará, Brazil, with the purpose of know the diversity of the species in the study area, contributing to the flora of Pará state and the Amazon Biome, in addition to supporting actions for the conservation and preservation of rare or endangered species. Due to the research, were searched by the family exsiccates where are incorporated at the BHCB, CEPEC, HCJS, IAN, INPA MG and RB herbarium, as well as collection expeditions in the study area. This resulted in the confirmation of 39 species distributed in 17 genera occurring in the study area.
