Distribution and habitat: — Eugenia pisiformis is known from collections from the state of Bahia through São Paulo in the Atlantic rainforest of Brazil . In the RNV, the species is found in the Mata Alta vegetation and near to periodically flooded areas. Phenology: —Flowering in August through October; fruiting in October through December ( Fig. 5 ). Taxonomic comments: —The species is assigned to Eugenia sect. Umbellatae . Eugenia pisiformis is morphologically similar to E. pruniformis due to its leaf blades shape, size, apices and indumentum, as well as the discolour leaf blades. However, Eugenia pisiformis differs from E. pruniformis by its leaf blades with innermost marginal vein 0.5–1 mm from the margin ( vs. 2.5–8 mm from the margin) and inflorescences in fascicles ( vs. inflorescences in raceme, which sometimes can be corymbose). The species is easily distinguished from all other species of the genus in RNV by the combination of its brownish indumentum, leaf blades generally oblong or narrow-elliptic, discolorous and with innermost marginal vein 0.5–1 mm from the margin, and inflorescences in fascicles.
