Inflorescences axillary or terminal, raceme with vegetative late proliferation, peduncle 1–4 mm long, rachis 4–14 mm long, puberulent; bracts 1–4 mm long, ovate, elliptic or oblanceolate, puberulent, deciduous at anthesis; 2–6 flowers; pedicels 5–11.5 mm long, puberulent; bracteoles 2–4.5 mm long, free, linear, apices acute, not reflexed, generally deciduous before anthesis; trichomes brownish or whitish. Flower buds 2.5–5 mm in diameter. Flowers with smooth, puberulent hypanthia; calyx lobes 4, free in the bud, 3–6.5 × 1.5–2.5 mm , elliptic or oblong, apices acute or obtuse, puberulent to glabrous; petals 4, oblong or obovate, oil glands inconspicuous; staminal ring puberulent; stamens with filaments 5–7 mm , anthers oblong or globose; style 5–7 mm , glabrous, stigma punctiform; ovary 2–locular, ovules 10–13 per locule, locule internally glabrous.

Distribution and habitat: — Eugenia bunchosiifolia is known from collections from the state of Espírito Santo to Paraná in the Atlantic rainforest of southeastern Brazil . In the RNV, the species is mainly found in the Muçununga vegetation, but also occurring in the Mata Alta . Phenology: —Flowering in August through November; fruiting in December through March ( Fig. 4 ). Taxonomic comments: —The species is assigned to Eugenia sect. Speciosae . Eugenia bunchosiifolia is morphologically similar to E. involucrata and E. puberula due to its raceme with vegetative late proliferation inflorescences, foliaceous calyx lobes (longer than 3 mm in length) but can be distinguished from both by its linear bracteoles which are deciduous before anthesis ( vs. bracteoles deltoid or wide-ovate and deciduous at or after anthesis). Eugenia bunchosiifolia is easily distinguished from all other species of the genus in RNV by its leaves with a yellow thickening margin. It is worth mention that these material were determined in herbaria as Eugenia dichroma O. Berg (1857: 290) , however, the type of E. dichroma does not present reproductive structures and as far as we are able to see it is a Eugenia sect. Umbellatae species, being morphologically distinct from the entity in RNV.
