9. Clidemia epibaterium De Candolle (1828: 157) . ( Figure 2 D ; 3 D, N .)

Lianas over decomposing logs. Green and smooth rhytidome. Branches prostrate, cylindrical, not winged, greenish,; branches, petioles with simple and dendritic trichomes, leaves both sides and fruits whit simple trichomes. Leaves opposite isophyllous; petioles circular 2.8–4.6 cm long; leaf blades 10.1–13.2 × 4.8–6.4 cm, chartaceous, discolored, symmetrical, elliptical, base rounded, apex acuminate, margins erose and ciliate, leaf veins 7, basal; ant domatia absent. Flowers axillary, solitary; bracts 0.5–0.9 mm long; bracteoles absent. Flowers 5-merous; pedicel 1–2, 4 mm long; hypanthium ca. 3 mm long, oblong, smooth; calyx simple, persistent; external lacinia linear ca. 1.6 mm long, internal lacinia in a membranous ring; petals 3.8 × 2.4 mm, white, ovate, with glandular trichomes, symmetrical, apex acute, margins not ciliate; stamens 10, isomorphic, anthers ca. 2.7 mm long, oblong, straight, apex attenuate, 1 apical pore, white, connective not prolonged, filament ca. 1.6 mm long, glabrous; ovary 2.6 mm long, inferior; style 5.3 mm long, straight, glabrous. Berry ca. 11 × 7.2 mm long, unripe fruit red, ripe fruit blue; seeds numerous, triangular.

Specimens examined: — BRAZIL. Amazonas, Manaus, RDS-Tupé, 27 April 2013, fr., A.L. Corrêa 215 (EAFM!, HUAM!, INPA!).

Additional specimens examined: — BRAZIL. Amazonas, Manaus, 20 June 1993, fl., J.EL. S. Ribeiro 932 ( INPA!).

Distribution and habitat: — Colombia, Guyana, Peru ( Berry et al. 2001). In Brazil it occurs in Amazonian forests ( Michelangeli & Reginato 2015). In the reserve it occurs in “terra firme”, on plateaus on shaded areas, and on decomposing logs.

Comments:— This s pecies is rare in the reserve. It can be easily recognized by the lianescent habit, the simple trichomes on both sides of the leaf, and the blue axillary fruits.
