Lenticels on current year's branchlets present. Internodes 0.2–1.5 cm. Stipules caducous, linear-triangular, 0.8–1 mm. Petiole glabrous, rough or grooved surface, 6–12 mm. Lamina elliptic, oblong (1:2), 5–13 X, 2–4.5 cm, papyraceous to coriaceous. Base acute or obtuse. Apex obtuse to acute, mucronate. Apex acuminate. Acumen 0.3–1.5 cm. Margin finement revolute, crenate, teeth conspicuous. Teeth 20–30 ca., over the entire length of the margin. Midbrid adaxially impressed, glabrous. Midbrid abaxially raised, glabrous. Secondary veins abaxially evident, 9–11 pairs. Tertiary veins abaxially evident. Ponctuation abaxiallly present.

Inflorescences.— Thyrsoid or thyrse, homocladic, with subthyrsoids alternate, proliferating.

Male flowers.— Thyrses axes solitary and axillary. Thyrses axes 0.3–4.5 cm. Cymes of order 1–2. Peduncles pubescent. Peduncles of order 1 1–1.5 mm. Pherophylls of order 1 at 0–3 tenth from the base. Peduncles of order 2 0.4–0.6 mm. Pherophylls of order 2 at 0–1 tenth from the base. Bracts linear-triangular, pubescent, 1.5–7 mm, margin entire. Pherophylls of order 1 opposite, linear-triangular, pubescent, 0.3–0.5 mm, margin entire. Male flowers 4 -merous. Calyx pubescent, 1.5–2.5 mm in diam., margin ciliate or dentate. Corolla 2.5–3 mm, petals connate on, petals 10–20 % of their length. Apex margin entire. Stamens at the anthesis equal to corolla. Rudimentary ovary pyramidal, glabrous.
