8. Clidemia capitellata (Bonpland 1806: 5) Don (1823:310) . ( Figure 2 F .)

Raceme 7.3–11.8 × 3.5–6.1 cm, axillary, with simple stellate and glandular caducous trichomes; bracts linear, persistent, with simple trichomes; bracteoles with simple persistent trichomes. Flowers 4-merous, sessile; hypanthium 0.8–1.3 mm long, campanulate, smooth; calyx simple, persistent, external lacinia triangular; internal lacinia oval, glabrous; petals 4.1–5.5 × 3.1–3.5 mm, white, oval, symmetrical, apex rounded, base truncate, margins not ciliate, glabrous; stamens 10, isomorphic, anthers 1.6–2.2 mm long, oblong, straight, apex attenuate, 1 apical pore, connective not prolonged, filament 2.3–2.7 mm long, glabrous; ovary ca. 2.1 mm long, inferior, placentation axillary intrusive, 5-locular, with glandular trichomes; style 5.1–5.5 mm long, straight, glabrous.

Specimens examined: — BRAZIL. Amazonas , Manaus, RDS-Tupé, 12 November 2012, fl.fr., A. L. Corrêa 101 ( EAFM!, HUAM!, INPA!) ; 06 December 2012, fl.fr., A. L. Corrêa 117 ( EAFM!, HUAM!, INPA!) .

Distribution and habitat: —From Southern Mexico to Brazil ( Berry et al. 2001). In Brazil it occurs in Amazonian florest ( Michelangeli & Reginato 2015). In the reserve it occurs in “terra firme”, more precisely on slopes on clay soil and low organic matter.

Comments: —This species is rare in the reserve. It can be recognized by the suprabasal leaf veins and racemose inflorescences.
