Distribution and habitat: — Eugenia repanda is known from collections from the state of Mato Grosso do Sul, Minas Gerais and Espírito Santo through Rio Grande do Sul in the Atlantic rainforest of Brazil. In the RNV, the species is found in the Mata Alta vegetation.

Phenology: —Flowering in February; fruiting in June through August ( Fig. 5 ).

Taxonomic comments: —The species can be assigned to Eugenia sect. Racemosae due to its raceme inflorescence with pedicels up to twice as long as flowers internodes. Eugenia repanda is easily distinguished from the other species in RNV by its raceme never corymbose, short, up to 6.5 mm long including the inflorescence’s peduncle and rachis, bracteoles ovate or triangular with acute apex, sometimes apiculate, and flowers with pedicels up to 2 mm long.
