Specimens examined: — BRAZIL. Espírito Santo: Linhares, Reserva Natural Vale – Estrada Braúna Preta , 27 May 1980, fl., I.A. Silva 168 (CVRD!, RB!, RBR!, SORO!) .

Distribution and habitat: — Eugenia handroi is known from collections from the state of Espírito Santo to 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 May ( Fig. 4 ).

Taxonomic comments: —The species is assigned to Eugenia sect. Hexachlamys . Eugenia handroi is easily distinguished from all other species of the genus in RNV by its generally pentamerous flowers, varying from 4 to 6 in the same plant. The specimen I.A. Silva 168 is the unique gathering of the species in the Espírito Santo state, collected more than 20 years ago, and presently represents the northern limit of distribution of Eugenia handroi .
