Description: Trees up to 12 m tall; young branches slightly flattened, with tiny interpetiolar ridges, densely covered by ferruginous or canescent, sessile-stelate to stipitate-stellate trichomes. Leaves discolorous; petioles 1–4 cm; blades 7.5–26 x 2.5–9 cm, elliptic to lanceolate, apex acuminate, sometimes caudate, base acute to shortly decurrent, margin entire, sometimes slightly repand, mainly in the superior third, membranaceous, very delicate, longitudinal nerves 3, with an additional faint, marginal pair, supra-basal, 3–13 mm above the base, abaxial surface with dense, rarely sparse, ferruginous or canescent, indument consisting of sessile-stellate trichomes, ca. 0.1–0.2 mm diam. Panicles 2–10 x 3–8 cm, glomerulate, terminal, usually with accessory branches, densely covered by sessile-stellate and stipitate-stellate trichomes ca. 0.1-0.2 mm diam.; bracts and bracteoles lanceolate, up to 2 mm long, caducous. Flowers 5-merous. Hypanthium 1.3–1.8 mm long, campanulate, inner surface glabrous, outer densely covered by sessile-stellate trichomes, ca. 0.1 mm diam.; torus glabrous. Calyx lobate, caducous in fruit, inner surface gabrous, outer with trichomes similar to the ones on the hypanthium; tube 0.3-0.4 mm long, inner lobes 0.1-0.2 mm long, outer teeth subulate. Petals 2-2.1 x 1.2 mm. Stamens white, isomorphic; filaments 1.7-1.8 mm long, glabrous; connectives up to 0.3 mm prolonged below the thecae, unappendaged; anthers 1.5-2 mm long, oblong, with a single terminal, ventrally displaced, moderate pore, ca. 0.2 mm diam. Ovary 0.7-0.8 mm long, 1/3 adherent to the hypanthium, 2-3-locular, apex covered by sessille-stellate trichomes; style 2.3-3 mm long, straight to curved, punctiform, glabrous. Fruits up to 3.4 x 3 mm, purple, 4-13 seeds.
