Habit, vegetative morphology.— Shrub, evergreen, 2–3 m tall. Current year's branchlets glabrous. Branchlets older than one year smooth or furrowed or rough, brownish or reddish (jaunâtre), glabrous. Lenticels on current year's branchlets absent or hardly visible. Internodes 0.01–0.5 cm (les feuilles se recouvrent). Stipules caducous, linear-triangular, 0.4–1 mm. Petiole glabrous, smooth surface or rough or grooved surface, 1–2 mm. Lamina ovate to elliptic, orbiculate (1:1) to oblong (1:2), 0.6–1.4 X, 0.4–0.8 cm, coriaceous, glabrous abaxially (jeunes feuilles poilues sur la marge). Base acute to rounded (décurrente). Apex rounded to acute, mucronate or not mucronate. Apex rounded. Margin plane (mais munie d'un bourrelet), entire or dentate (sur certaines feuilles, rares), teeth inconspicuous or conspicuous. Teeth 2–6 ca., on the distal half of the margin. Midbrid adaxially impressed or flat, glabrous. Midbrid abaxially raised, glabrous. Secondary veins abaxially obscure, 3–4 pairs (mais parfois invisibles). Tertiary veins abaxially obscure. Ponctuation abaxiallly absent (parfois incolores).

Inflorescences.— Solitary dichasium.

Male flowers.— Cymes of order 1–2. Peduncles glabrous. Peduncles of order 1 4–5 mm. Pherophylls of order 1 at 1–3 tenth from the base. Peduncles of order 2 2–3 mm. Pherophylls of order 2 at 0–1 tenth from the base. Pherophylls of order 1 opposite, linear-triangular, glabrous, 0.7–1 mm, margin entire. Male flowers 5–6 -merous, white. Calyx glabrous, 5–8 mm in diam., margin entire. Corolla 5–6 mm, petals connate on, petals 20–30 % of their length. Apex margin entire. Stamens at the anthesis shorter than corolla. Rudimentary ovary subglobulous or flattened, glabrous.

Female flowers.— Cymes of order 1. Peduncles glabrous or pubescent. Peduncles of order 1 0.5–3 mm. Pherophylls of order 1 at 2–4 tenth of the base. Pherophylls of order 1 opposite, deltoids or linear-triangulate, glabrous, 1–1.5 mm, margin entire. Female flowers 5–6 -merous, white. Calyx glabrous, margin entire, 4–7 mm in diam. Corolla 5–6 mm, petals connate on, petals 30–40 % of their length. Apex margin entire (possibly beaded). Staminodes sagittate, glabrous. Ovary ovoid or spherical, glabrous, stigma mamillate, stigma glabrous.

Fruits.— Fruit spherical, 5–8 mm in diam., 5–10 mm.

Distribution, ecology.— South America, Peru Bolivia, 3200–4000 m, Forêt.

Flowering.— March to April or October.
