Abstract
Nomenclatural updates are presented for the genus Myrcia. New combinations are presented for Myrcia antonia, M. eugeniopsoides, M. reitzii and M. cionei (based on Marlierea antonia, M. eugeniopsoides, M. reitzii and Myrcianthes cionei), and four new names are proposed: Myrcia ferruginosa, M. vellozoi, M. multipunctata and M. insigniflora (based on Eugeniopsis silvatica, Myrtus racemosa, Eugenia laevigata and Marlierea glazioviana). Distribution data of the species are provided. The genus Myrcia currently comprises ca. 400 species, distributed from Mexico and the Caribbean to northern Argentina. All the species presented here are endemic to Brazil.
