Eugenia dittocrepis O. Berg (1857–1859: 292). Type :— BRAZIL . “Habitat in silvis ad villam Ega in prov. do alto Amazonas”, Pöppig 3109 ( syntypes : P [01902445], image, G [00223425], image, BM [000953773], image). ( Fig 3 AB) FIGURE 3. A–B.

Twigs glabrous. Leaves with petioles 9–10 mm long, glabrous, unchanneled or shallowly channeled; blades elliptic, oblong, or oval, 10–12.1 × 3.6–5.1 cm , glabrous, chartaceous, discolorous; glands not seen; base cuneate or rounded; apex acute, cuneate, rarely rounded; midvein adaxially flat; lateral veins visible, not arched, 10 to 15 pairs; intra-marginal vein 1–3 mm from the margin, margin revolute. Inflorescence axillary, a fascicle, the axis 1–2 mm , glabrescent; bracts orbicular, 0.5 × 0.5 mm , glabrous, persistent in the fruit; pedicels 4–9 mm long, glabrous; bracteoles ovate, 1.5 × 1 mm , glabrous, persistent in the fruit; flower buds globose, 3–4 × 5–6 mm , not constricted above ovary; calyx-lobes free, four, orbicular, 1.4–2 × 1–2 mm , glabrous, not reflexed, persistent in the fruit; ovary not seen. Immature fruit globose, ca. 1 cm diameter, glabrous, surface smooth. Note:— E . dittocrepis may be recognized by its leaves, which are green-yellowish adaxially and reddish-brown abaxially in the dried material, with revolute margins; its inflorescence, which is a glabrescent fascicle with persistent bracteoles in fruit; and its globose, glabrous, and smooth fruit. This species is morphologically related to E . stictopetala but can be distinguished by its revolute leaf margins (vs. flat) and its discolorous leaves (vs. concolorous leaves). Distribution and habitat:— Known from Colombia , Ecuador , Peru , Venezuela and northeastern and northwestern Brazil ( Acre , Amazonas, Maranhão , Mato Grosso and Pará states) (POWO 2020, Flora do Brasil 2020 ). In Amazonian Maranhão , E . dittocrepis was found growing along waterways. Phenology:— Fruiting in April. Specimens examined:— BRAZIL .
