Type:— BRAZIL, Pará, Almeirim, Gleba Monte Dourado, floresta secundária de terra firme, J.M. Pires & N.T. Silva 2015 (holotype: MG). (Fig. 2 E-F.)
Shrubs 2– 17 m. Twigs glabrous, sparsely pubescent when young, the indumentum whitish. Leaves with petioles 3–8 mm long, glabrous or puberulent, channeled or shallowly channeled; blades elliptic to broadly so, lanceolate, ovate or oblong, 5.2–14 × 2.5–6.3 cm, glabrous or sparsely pubescent, the indumentum brownish, chartaceous, concolorous; glands conspicuous; base rounded, cuneate or acute; apex acute or attenuate, rarely acuminate; midvein adaxially sulcate; lateral veins visible, not arched, 8 to 10 pairs; intramarginal vein 1–3 from the margin, margin revolute. Inflorescence axillary or terminal, raceme simple, the axis 4.2–10.4 cm long; bracts not seen, caducous before anthesis; pedicels 2–9 mm long, glabrous; bracteoles ovate to broadly so, or deltate, 1–2 × 1–3 mm, glabrous, persistent in the fruit; flower buds globose, 5 × 5 mm, not constricted above ovary; calyx-lobes free, four, orbicular, 2–3.5 × 3–4 mm, glabrous, not reflexed, persistent in the fruit; ovary 2-locular. Immature fruits oblong or ellipsoid, 1.4–1.7 × 1.1–1.3 cm, glabrous or puberulent, surface smooth.
Note:— Eugenia caducibracteata may be recognized by its adaxially sulcate leaf midvein; a simple raceme with a long axis; large flower buds (5 × 5 mm); and bracts that are caducous before anthesis.
Distribution and habitat:— Known from northeastern and northwestern Brazil (Amazonas, Maranhão and Pará states) (Mazine & Souza 2009). E. caducibracteata can be found growing in unflooded tropical moist forest (Mazine & Souza 2009) and in Amazonian Maranhão was found growing in secondary forest.
Phenology:— Flowering in February and December and fruiting in August.
