Diagnosis

Leaves simple, unlobed; petiole short. Lamina elliptic, rarely obovate, occasionally asymmetrical. Base angle of lamina acute, rarely obtuse; base shape rounded, slightly cordate or cuneate, asymmetrical. Apex angle of lamina acute, rarely obtuse; apex shape rounded or straight, often mucronate, rarely spinose. Margin entire or serrate in upper part of lamina, rarely toothed from lower third part of leaf. Tooth spacing irregular, one order of teeth; sinus shape rounded, tooth shape concave/convex to straight/straight, tooth apex nonspecific. Primary venation pinnate brochidodromous, often semicraspedodromous in upper part of lamina or mix craspedodromous/brochidodromous. Secondaries alternate to subopposite, often irregular, with simple agrophic veins in middle part of lamina; intersecondaries rarely present. Tertiaries alternate percurrent to mixed opposite– alternate percurrent. Fourth order vein fabric reticulate. Ordinary epidermal cells of costal area of lower lamina surface with straight anticlinal walls of various sizes and shapes: square, polygonal, rectangular or with transverse anticlinal walls oriented obliquely to longitudinal axis of cell; stomata anomocytic, with four subsidiary cells. Epidermal cells of upper leaf surface rectangular, rarely polygonal, stomata and trichome bases absent.
