Stipules caducous, linear-triangular, 0.5–0.8 mm. Petiole glabrous, rough or grooved surface, (2–)5–12(–15) mm. Lamina elliptic or obovate, oblong (1:2) or lanceolate (1:3), (2.5–)5–10(–11.8) X, (1–)2–4.5(–5) cm, coriaceous, glabrous abaxially. Base cuneate to acute. Apex obtuse. Apex rounded or acuminate. Acumen 0.5–1 cm. Margin revolute, crenate or dentate, teeth conspicuous. Teeth 8–14 ca., over the entire length of the margin. Midbrid adaxially impressed to flat, glabrous. Midbrid abaxially raised, glabrous. Secondary veins abaxially evident, 6–11 pairs. Tertiary veins abaxially obscure. Ponctuation abaxiallly absent.

Inflorescences.— Thyrsoid, heterocladic, with subthyrsoids alternate (parfois quelques axes à dichasium subopposés).

Bracts deltoids, glabrous, 0–0.5 mm, margin entire. Pherophylls of order 1 opposite, linear-triangular, glabrous, 0.3–0.5 mm, margin entire. Male flowers 4–5(–6) -merous. Calyx glabrous, 2–2.5 mm in diam., margin entire (très finement denticulé à la loupe). Corolla 2–3 mm, petals connate on, petals 10–15 % of their length. Apex margin ciliate (?). Stamens at the anthesis equal to corolla. Rudimentary ovary pyramidal, glabrous.

Female flowers.— Thyrses axes solitary and axillary. Thyrses axes 0.5–4.5 cm. Cymes of order 1. Peduncles pubescent (poils très courts). Peduncles of order 1 2–5 mm. Pherophylls of order 1 at 0–2 tenth of the base. Bracts linear-triangulate, pubescent (poils très courts et peu nombreux), 0–0.5 mm, margin entire. Pherophylls of order 1 opposite, linear-triangulate, pubescent (poils très courts et peu nombreux), 0–0.3 mm, margin entire. Female flowers 4–5(–6) -merous. Calyx pubescent (poils peu nombreux et courts), margin ciliate or dentate (visible à la loupe), 2–3 mm in diam. Corolla 2–3 mm, petals connate on, petals 20–30 % of their length. Apex margin entire (possibly beaded). Staminodes sagittate, glabrous. Ovary spherical, glabrous, stigma capitate, stigma glabrous.

Fruits.— Fruit red to black (violacé sombre), spherical, 4–5 mm in diam., 4–5 mm.

Distribution, ecology.— South America, Brazil (DF, Goiás, Paraná, Bahia, S¦o Paulo) Paraguay (San Pedro, Amambay, Canindeyú), 950 m, Habita terrenos húmedos( riberas de arroyos, isla de monte en campos). Frecuente en vegetación de tipo cerrado.

Flowering.— January to April or October to December.
