    Note
    Eugenia salacifolia is related to E. macrantha O. Berg (E. sect. Umbellatae O. Berg), however the new species has auxotelic (vs fasciculate) inflorescences, larger (3.4 – 11.9 mm long vs c. 2 – 4 mm long), persistent bracteoles (vs caducous) and larger calyx lobes (10.6 – 14.4 mm long vs 4 – 8 mm long).

    Eugenia salacifolia belongs to Eugenia sect. Phyllocalyx which is characterised by showy calyx lobes and bracteoles and fruits with persistent bracteoles. This section has auxotelic inflorescences in which the axis of the inflorescence continues growth beyond the flowering region. Eugenia sect. Phyllocalyx is also distinct in the degree of branching and/or number of internodes or their inflorescence elongation. In young branches, species have 2 – 4 or even more flowers united in lateral or terminal “inflorescences”. But, when the shoots are well developed, these appear as solitary flowers along the branch. This inflorescence arrangement is particularly important to distinguish E. salacifolia from E. macrantha which belongs to Eugenia sect. Umbellatae. The latter species has flowers arranged in determinate inflorescences: fascicles, glomerules or racemes. Besides the morphology of the inflorescence, E. salacifolia differs from E. macrantha in having larger bracteoles (3.4 – 11.9 mm long vs c. 2 – 4 mm long) and larger calyx lobes (10.6 – 14.4 mm long vs 4 – 8 mm long).

    Eugenia salacifolia is so named in recognition of its leaves that are similar in shape and size, to the leaves of species of Salacia (Celastraceae).

    Distribution
    Eugenia salacifolia occurs in the municipality of Itamarandiba, Minas Gerais, Brazil (Map 1).
    Ecology
    Between 1000 – 1135 m a.s.l. in the north-centre of the state of Minas Gerais, Brazil. This region is tropical with two rainy periods during the year (IBGE 2016). The municipality of Itamarandiba forms part of the central portion of the Espinhaço Range and is heavily influenced by the Cerrado biome.
    Conservation
    Specimens of Eugenia salacifolia, collected as E. magnisepala, were found outside a protected area surrounded by Eucalyptus plantations. Eugenia salacifolia is considered Endangered (EN) under the IUCN (2016) conservation status criteria B1ab(iii). Criterion B1 recognises an extent of occurrence of less than 5,000 km2, criterion “a”, occurrence in less than five localities and “b(iii)”, a continuing decline in the area and quality of the habitat.
    Phenology
    Eugenia salacifolia is known to flower in January and fruit in August.
