Diagnosis

Lamina ovate-elliptical or elliptical in outline, shallowly to moderately bilobate, with pulvinate petiole and untoothed margin. Laminar base slightly or shallowly cordate, lobe apex acute. Primary venation basal actinodromous with 7–9 basal veins. Midvein terminated at the bottom of a narrow sinus. Lateral primaries straight or curved, and the innermost pairs reaching the lobe apex and outer pairs approaching to the laminar margin. Secondary veins craspedodromous. Intersecondary veins present. Tertiary veins opposite and alternate percurrent. Quaternary veins forming irregular polygons. Areolation well developed. Freely ending veinlets unbranched. Marginal ultimate veins absent; leaves hypostomatic. Epidermal cells on both surfaces, similarly quadrangular or pentagonal, with straight or slightly curved anticlinal walls. Stomatal complexes paracytic, randomly oriented.
