blade elliptic or obovate, symmetric. Leaf base cuneate, rarely rounded. Leaf apex acute. Leaf margin
irregularly serrate, entire in the lower 1/3 (or 1/2) part
of leaf blade. Teeth small acute broadly-triangular. Venation pinnate, craspedodromous in the upper part
and brochidodromous or semicraspedodromous in the
