Abstract
Psidium species of Macaé de Cima, Rio de Janeiro, Brazil were revisited after just over 20 years since the publication of the Myrtaceae study for this area of Atlantic forest, which currently constitutes an Environmental Protection Area. The species identification was based on analysis of herbarium collections, and observation of individuals in the field. The results include the taxonomic treatment, identification key, comments and photographic record of the species. The number of species of Psidium in the study area was expanded to three for six species, one of which P. ovale represents a new record for the state of Rio de Janeiro. The results showed the need for continued studies of flora, especially in high-diversity areas, and its importance for conservation of species and protected areas management.
