Abstract

A new species of the genus Pleroma, endemic to the state of Paraná, is described. Pleroma joelsilvae is morphologically similar to Pleroma oleifolium and Pleroma ursinum. Here we present the taxonomic description for the species, taxonomic comments, distribution map, illustrations made with photos from herbarium specimens, photos of the species in vivo, and conservation status assignments. According to our assessments based on IUCN criteria, P. joelsilvae is Critically Endangered (CR), because its occurrence is very restricted, and its populations are small and occurring in unprotected areas. To facilitate its recognition, we present an updated identification key for the species of Pleroma that occur in Paraná. Pleroma joelsilvae is a tribute to Joel Morais da Silva, for his extensive work as a plant collector on the staff of the “Museu Botânico Municipal de Curitiba”.
