Cotyledons elliptic to orbicular, midrib raised on the upper surface. First pair of leaves with teeth on the upper part of the leaf blade margin, midrib raised on the upper surface. At the tenth leaf stage: leaf blade elliptic, apex shortly acuminate, base attenuate, margin toothed, teeth small, serrate, confined to the upper part of the leaf blade; midrib raised on the upper surface; stipules small, elongate-triangular.
