Distribution and habitat: — Eugenia beaurepairiana is known from collections from the state of Bahia to Rio Grande do Sul in the Atlantic rainforest of Brazil . In the RNV, the species is mainly found in the Mata Alta . Phenology: —Flowering in December through January; fruiting in April through May ( Fig. 4 ). Taxonomic comments: —The species is assigned to Eugenia sect. Pilothecium . Eugenia beaurepairiana is morphologically similar to E. supraaxillaris due to its size and shape of leaves and determinate inflorescences. However, Eugenia beaurepairiana can be distinguished by its pubescent abaxially leaves with midvein sulcate adaxially ( vs. glabrous abaxially and midvein slightly raised adaxially in E. supraaxillaris ), and the pubescent inflorescences ( vs. glabrate or glabrous). The combination of thyrsoid inflorescences and yellow fruits when ripe distinguish the species from all other of the genus in RNV.
