Flowers 5-merous, sessile; hypanthium ca. 1.9 mm long, oblong, smooth, with stellate-stipitate persistent trichomes; calyx simple, persistent; petals ca. 3.5 × 1.7 mm, white, obovate, symmetrical, apex rounded, base truncate, margins not ciliate, glabrous; stamens 10, heteromorphic, smaller anthers 2–2.2 mm, larger anthers 2.7–3 mm long, white, linear, straight, apex truncate,1 apical pore, anther base with 4 lobes, connective not prolonged, smaller filaments 3–3.5, larger filaments 4.4–4.6 mm long, glabrous; ovary 1.5–1.9 mm long, half-inferior, placentation axillary, 3-locular, glabrous; style 8.2–8.3 mm long, straight, with trichomes.

Specimens examined:— BRAZIL. Amazonas , Manaus, RDS-Tupé, 05 December 2012, fl., A. L. Corrêa 106 ( EAFM!, HUAM!, INPA!) ; 01 February 2013, fl., A. L. Corrêa 143 ( EAFM!, HUAM!, INPA!) .
Distribution and habitat:— Colombia, Venezuela, Guyana, French Guiana, Bolivia ( Goldenberg et al. 2013). In Brazil it occurs in Amazonian forests ( Goldenberg & Caddah 2015). In the reserve, it occurs in “terra firme” plateaus, on well drained, clay soil with a lot of organic matter.
Comments:— This species is rare in the reserve. It can be recognized by the light gray and smooth rhytidome, spicate-whorled and terminal inflorescences and anther base with 4 lobes.
