Distribution and habitat: — Eugenia platyphylla is known from collections from the state of Bahia and Espírito Santo the Atlantic rainforest of Brazil. In the RNV, the species is found in the Mata Alta vegetation and in the transition of this vegetation to the Muçununga.
Phenology: —Flowering in September through November; fruiting in November through February and April (Fig. 5).
Taxonomic comments: —The species is assigned to Eugenia sect. Excelsae. Eugenia platyphylla is morphologically similar to E. excelsa due to its inflorescences in fascicle, bracteoles deciduous at or after anthesis, and fruit globose, dark purple or whitish when ripe. The diagnostic features for both are presented in the comments under E. excelsa and in Table 1. Fruits dark purple and whitish were found in the field.
