Type:— BRAZIL. Mato Grosso. Chapada dos Guimarães, Parque Nacional da Chapada dos Guimarães, Véu da Noiva, ao longo do rio Coxipozinho, trilha para a base da cachoeira, F. F. Mazine et al. 1072 (holotype: ESA; isotype: K [001018882], image). (Fig. 2G)

Shrubs 3– 15 m. Twigs densely pubescent, the indumentum whitish. Leaves with petioles 2–13 mm long, glabrous, channeled; blades oblanceolate, oblong,obovate or elliptic, 2.5–20× 1.8–8.5cm, glabrous, chartaceous or subcoriaceous, discolorous; glands conspicuous; base cuneate, acute or obtuse; apex acute, acuminate or cuspidate; midvein adaxially flat; lateral veins visible, not arched, 8 to 13 pairs; intra-marginal vein 1–3 mm from the margin, margin revolute. Inflorescence axillary, raceme simple, the axis 1.8–6 cm long, sparsely pubescent or densely pubescent, the indumentum whitish; bracts ovate to broadly so, or deltate, 0.1–0.2 × 0.3 mm, pubescent, persisting in the fruit; pedicels 2–10 mm long, pubescent; bracteoles ovate or deltate, 0.2 × 0.5 mm, glabrescent or densely pubescent; persisting in the fruit; flowers buds globose, 1–2 × 2 mm, not constricted above ovary; calyx-lobes partially fused in the lower third of the bud, four, orbicular, 0.3–2 × 0.5–1.9 mm, glabrescent or densely pubescent, not reflexed, persistent in the fruits; ovary 2-3-locular. Immature fruits globose, 0.6–1.1 × 0.5–1.7 cm, glabrous, surface smooth.

Note:— Eugenia densiracemosa may be recognized by its chartaceous or subcoriaceous leaves; with intra-marginal vein 1–3 mm from the margin; long simple racemes (1.8–6 cm), generally with a long pedicel (2–10 mm long). This species is morphologically similar to E. florida, but can be distinguished by its 8 to 13 pairs of unarched lateral veins (vs. arched) that are visible adaxially and abaxially (5 to 8 pairs, visible abaxially).

Distribution and habitat:— Known from French Guiana and central, northeastern and northwestern Brazil (Acre, Ceará, Goiás, Maranhão, Mato Grosso, Pará and Tocantins states) (POWO 2020, Flora do Brasil 2020). E. densiracemosa grows in forest formations along rivers and streams borders, in Cerrado and Amazonia biomes (Mazine & Faria 2013). In Amazonian Maranhão it was found in “terra firme” and secondary forests.

Phenology:— Flowering in January, August and October to December and fruiting in March and August.
