Eugenia stictopetala Martius ex De Candolle (1828: 270) . Type:— BRAZIL . Habitat in campis inter. Provinciae Minar, C. F. P. Martius s.n . ( holotype : M [0171122]). ( Fig 2 N-P) Shrubs 0.2– 8 m . Twigs glabrous. Leaves with petioles 8–10 mm long, glabrous, channeled; blades elliptic to broadly so, oblong, oval or rounded, 6.5–13.1 × 4.3–6.4 cm , glabrous, chartaceous, concolorous; glands conspicuous and dark; base cuneate or rounded; apex acute or rounded; midvein adaxially impressed; lateral veins visible, not arched, 5 to 15 pairs; intra-marginal vein 1–5 mm from the margin, margin flat. Inflorescence axillary, a fascicle, the axis ca. 1 mm long or less; bracts orbicular, 0.6 × 2.4 mm , glabrous, persistent in the fruit; pedicels 5–19 mm long, glabrous or sparsely pubescent; bracteoles elliptic or oblong, 0.7–1 × 2–5 mm , glabrous, persistent in the fruit; flower buds globose, 4–6 × 2–5 mm , not constricted above ovary; calyx-lobes free, four, orbicular or oblong, 0.5–2.5 × 1.5–3 mm , glabrous, not reflexed, persistent in the fruit; ovary 2–locular. Immature fruit globose, 0.9–1 × 0.6–0.8 cm , glabrous, surface with glands marked. FIGURE 4. A–D. Eugenia polystachya . A. Habit. B. Inflorescence in a simple raceme. C. Flower bud. D. Fruit. E–G.

Note:— Eugenia stictopetala may be recognized by its glabrous chartaceous leaves with dark glands visible; and its orbicular or oblong calyx-lobes; and globose fruit. This species is morphologically related to E . dittocrepis but can be distinguished by its flat marginal leaf vein (vs. revolute) and concolorous leaves (vs discolorous leaves). Distribution and habitat:— Known from Costa Rica , French Guiana, Guyana , Panamá , Peru , Suriname , TrinidadTobago, Venezuela and Brazil , where it is widely distributed (POWO 2020, Flora do Brasil 2020 ). In Amazonian Maranhão , E. stictopetala was found growing in secondary forests and along roads. Phenology:— Flowering from March to July and fruiting in April. Specimens examined:— BRAZIL .
