10. Clidemia heteroneura ( De Candolle 1828: 506) . Cogniaux (1888: 506). ( Figure 3 E .)

Shrubs 1.1–1.4 m tall. Green and smooth rhytidome. Branches erect, cylindrical, not winged, greenish, with simple and glandular trichomes; petioles, leaves, hypanthium with simple trichomes. Leaves opposite isophyllous; petioles striate 13.2–36.9 mm long; leaf blades 14.8–21.7 × 4.7–7 cm, chartaceous, concolorous, symmetrical, oblong-lanceolate, or lanceolate, base attenuate, apex acuminate, margins entire and ciliate, leaf veins 6, suprabasal; ant domatia absent. Inflorescences axillary; bracts linear, persistent; bracteoles absent. Flowers 4-merous, sessile; hypanthium 1.2–1.8 mm long, oblong, smooth, with simple persistent trichomes; calyx simple, persistent; external lacinia triangular, with simple trichomes; internal lacinia in a membranous ring; petals 1.9 × 1.5 mm long, white, ovate, symmetrical, apex acute, base truncate, margins not ciliate, glabrous; stamens 8, isomorphic, anthers 1.6–1.8 mm long, white, oblong, straight, apex attenuate, 1 apical pore, connective not prolonged, filament 2–2.3 mm long, glabrous; ovary inferior, placentation axillary, 4-locular, with glandular trichomes; style 6.3–6.8 mm long, straight, glabrous. Berry 7.6 × 8.3 mm, unripe fruit green, ripe fruit blue, glabrous; seeds numerous, oblong-winged.

Specimens examined: — BRAZIL. Amazonas , Manaus, RDS-Tupé, 31 January 2013, fr., A. L. Corrêa 140 ( EAFM!, HUAM!, INPA!) ; 01 February 2013, fl., fr., A. L. Corrêa 145 ( EAFM!, HUAM!, INPA!) ; 27 April 2013, fr., A. L. Corrêa 211 ( INPA!) ; 27 April 2013, fr., A. L. Corrêa 213 ( EAFM!, HUAM!, INPA!) .

Distribution and habitat: — Colombia, Venezuela ( Berry et al. 2001). In Brazil it occurs in Amazonian forests ( Michelangeli & Reginato 2015). In the reserve, it occurs in “ campinarana”, in shaded environments with a lot of organic matter.

Comments: —This s pecies is common in the reserve. Among the species from the “campinarana”, it can be distinguished by the axillary flowers and the oblong-winged seeds.
