Internodes 1–1.5 cm. Stipules caducous, linear-triangular, 0.5 mm. Petiole glabrous, smooth surface, 2–3.5 mm (sinueux). Lamina elliptic, orbiculate (1:1) to oblong (1:2), 4–8.5 X, 1.5–4.5 cm, papyraceous to coriaceous, glabrous abaxially. Base cuneate to acute. Apex rounded, not mucronate. Apex acuminate or retuse (rarement). Acumen 1–2 cm. Margin revolute, entire (irrégulière). Midbrid adaxially raised, glabrous. Midbrid abaxially raised, glabrous. Secondary veins abaxially evident, 5–8 pairs. Tertiary veins abaxially evident. Ponctuation abaxiallly absent.
