At the tenth leaf stage: leaf blade obovate, apex acuminate, base cuneate, upper surface glabrous, midrib and lateral veins raised on the upper surface of the leaf blade; two glands present on the upper surface of the leaf blade at its junction with the petiole; petiole hairy towards the apex; stipules caducous, small, triangular, hairy.
