- Diagnosis
- Small, broadly ovate or suborbicular, moderately or deeply bilobate leaves. Petioles glabrescent or hairy, bearing thicken upper and lower pulvini. Lobe apexes slightly acuminate, obtuse or rounded. Laminar bases shallowly to deeply cordate. Margin entire. Primary veins basal actinodromous, 7-9 in number. The midvein terminated in a short or long spine within a narrow or flaring sinus. Lateral primary veins straight or curved, branched or unbranched, approaching to the margin. Secondary veins eucamptodromous. Intersecondary veins present. Tertiary veins percurrent or ramified, mostly convex, sinuous or rarely straight. Quaternary veins percurrent, forming irregular polygons. Aerolation well developed. Freely ending veinlets mostly unbranched. Marginal ultimate veins absent.
