Distribution and habitat: — Eugenia punicifolia is a widespread species known from collections in the whole Brazilian territory and surrounding countries. In the RNV, the species is found in the Muçununga, where it grows in the understory and can reach the canopy, and Campo Nativo vegetation, predominantly grassy vegetation.

Phenology: —Flowering in June through September; fruiting in August through October ( Fig. 5 View FIGURE 5 ).

Taxonomic comments: —The species is assigned to the Eugenia sect. Umbellatae . Eugenia punicifolia is morphologically similar to E. arenaria due to its size of leaf blades and floral features, and lack of indumentum (except on its staminal disk). The diagnostic features between both can be see in the comment under E. arenaria . Although the specimen D.A. Folli 6911 is morphologically identical to the others, it presents 23 m of height, a discordant value from which is commonly found among the records for the RNV (up to 6 m high). As the Muçununga ’s canopy usually reaches 10 m of height, being unusual plants emerging from it ( Simonelli et al. 2008), we believe that a field misannotation could have happened. Therefore, this variation was not included in the description herein presented.
