Estudo taxonômico de espécies da Família Myrtaceae com vistas ao manejo da vegetação secundária, no Município de Bragança, Pará

Abstract

The Myrtaceae are found predominantly in tropical regions, with approximately 1,000 species occurring in Brazil. In secondary forest areas, the family can be of great economic importance and have a good potential for use. In the Amazon, in general, the Myrtaceae are little studied and there is a great need for taxonomic studies. This work, developed in the municipality of Bragança, Northeast Paraense, aimed to identify, describe and illustrate the species of Myrtaceae in three areas of successional forests. The collections of the MG and IAN herbaria were analyzed and new collections were made. All the material collected was identified, described and illustrated. The identified species received identification keys, geographic distribution, vernacular name, and taxonomic comments. Based on the literature survey, the species cited in scientific studies conducted in the municipality and their potential use were listed. Eleven species and four genera (Eugenia, Myrcia, Myrciaria and Psidium) were found. The genera Myrcia and Eugenia presented the highest number of species, four each. In the bibliographical survey 21 species and 8 genera were listed. Of these, 10 species were not found in herbaria, and two do not occur in the Amazon. Due to the number of species mentioned in scientific studies in the municipality and not located in herbaria, it can be assumed that the identification or collections of Myrtaceae from secondary forests are being neglected.
