Paniculate 4.7–8 × 2.4–4.2 cm, terminal or pseudoaxillary; bracts 1–1.6 mm long, lanceolate, caducous; bracteoles 0.2–0.7 mm long. Flowers 5-merous; pedicel 1.9–4.1 mm long; hypanthium ca. 1.7 mm long, urceolate, smooth; calyx simple, persistent; lacinia triangular; petals 3 × 3.6 mm, white, obovate or ovate, symmetrical, apex rostrate, base truncate, margins not ciliate, glabrous; stamens 10, isomorphic, anthers 1.6–2.6 mm long, white, oblong, curved, apex attenuate, 1 apical pore, appendaged, filament 3–3.6 mm long, glabrous; ovary ca. 1.8 mm long, inferior, placentation axillary intrusive, 3-locular, with simple trichomes; style 7.1–7.8 mm long, curved, glabrous. Berry 9.2 × 9.5 mm, unripe fruit green, ripe fruit purple; seeds numerous, triangular.

Distribution and habitat: — Nicaragua, Costa Rica, Bolivia, Colombia, Ecuador, Guyana, Peru, Venezuela, Suriname ( Berry et al. 2001). In Brazil it occurs in Amazonian forests ( Michelangeli & Reginato 2015). In the reserve, it occurs in “terra firme”, in secondary vegetation and trail edges, on clay soil and low organic matter. Comments: —This species is frequent in the reserve. It can be easily recognized by the asymmetrical leaf base.
