Habit, vegetative morphology.— Tree or shrub, evergreen, 5–15 m tall. 10–20 cm dbh. Current year's branchlets glabrous or pubescent or hirsute (surtout à l'extrémité). Branchlets older than one year smooth or furrowed (parfois profondément cannelé), brownish or reddish (noirâtre), glabrous or pubescent, sparse trichomes or dense short trichomes or dense long trichomes. Lenticels on current year's branchlets present or absent or hardly visible. Internodes 0.4–2.7 cm. Stipules persistent, deltoid or linear-triangular, 0.5–3 mm. Petiole glabrous or pubescent (chez certaines feuilles de l'année), smooth surface or rough or grooved surface, 5–25 mm. Lamina ovate or elliptic or obovate, orbiculate (1:1) or oblong (1:2), 2.3–15 X, 1.5–9 cm, papyraceous or coriaceous, glabrous abaxially (les jeunes feuilles sont souvent couvertes de longs poils épars). Base acute or obtuse or rounded. Apex rounded or obtuse or acute, mucronate or not mucronate. Apex retuse or emarginate or rounded or acuminate. Acumen 0–0.8 cm. Margin plane or revolute (légèrement surtout à la base), crenate or dentate, teeth conspicuous. Teeth 4–26 ca., over the entire length of the margin. Midbrid adaxially impressed or flat, glabrous or pubescent on proximal half (entièrement pubescente chez les jeunes feuilles). Midbrid abaxially raised, glabrous or pubescent. Secondary veins abaxially evident, 4–12 pairs. Tertiary veins abaxially evident. Ponctuation abaxiallly present.

Inflorescences.— Solitary dichasium.

Male flowers.— Cymes of order 3–6 (les 3 à 4 premiers ordres sont avortés). Peduncles glabrous or pubescent (plut"t glabre, mais avec de longs poils par endroits). Peduncles of order 1 6–23 mm. Pherophylls of order 1 at 8–10 tenth from the base. Peduncles of order 2 3–15 mm. Pherophylls of order 2 at 8–10 tenth from the base. Peduncles of order 3 2–7 mm. Pherophylls of order 3 at 5–10 tenth from the base. Peduncles of order 4 1–3 mm. Pherophylls of order 4 at 5–10 tenth from base. Peduncles of order 5 1–2 mm. Pherophylls of order 5 at 5–10 tenth from the base. Bracts deltoids (une seule inflorescence avec bractée), glabrous, 3 mm, margin ciliate or dentate. Pherophylls of order 1 opposite, linear-triangular (avec comme deux stipules à leur base), glabrous or pubescent, 2–7 mm, margin entire or margin ciliate. Male flowers 4 -merous, white. Calyx glabrous or pubescent, 1.3–3.5 mm in diam., margin entire or margin ciliate or dentate. Corolla 1.5–3.5 mm, petals connate on, petals 30–50 % of their length. Apex margin entire or ciliate. Stamens at the anthesis shorter than corolla. Rudimentary ovary subglobulous or flattened, glabrous.

Female flowers.— Cymes of order 2–5 (ordres un à trois souvent avortés). Peduncles glabrous or pubescent. Peduncles of order 1 7–22 mm. Pherophylls of order 1 at 6–10 tenth of the base. Peduncles of order 2 2–10 mm. Pherophylls of order 2 at 7–10 tenth of the base. Peduncles of order 3 2–7 mm. Pherophylls of order 3 at 5–10 tenth of the base. Peduncles of order 4 1–3 mm. Pherophylls of order 4 at 5–9 tenth of the base. Peduncles of order 5 0–1 mm. Pherophylls of order 1 opposite, deltoids or linear-triangulate, glabrous or pubescent, 1–4.5 mm, margin entire or margin ciliate. Female flowers 4 -merous, white. Calyx glabrous or pubescent, margin ciliate or dentate, 2–3.5 mm in diam. Corolla 2–3 mm, petals connate on, petals 15–25 % of their length. Apex margin ciliate. Staminodes sagittate, glabrous. Ovary spherical, glabrous, stigma mamillate or capitate or columnar, stigma glabrous.

Fruits.— Fruit black or green, ovoid or spherical, 1.5–5 mm in diam., 2–6 mm.

Distribution, ecology.— South America, Colombia Ecuador, 1500–2800 m, Forêt à brouillard, forêt à brouillard humide, forêt tempérée humide, forêt primaire.
