Diagnosis
Herbaceous plant with leaves arising directly from a rhizome. Leaves alternate, simple, petiolate, peltate (attachment of lamina very eccentric). Base wide obtuse, lobate. Apex obtuse, rounded. Primary venation actinodromous, 9 primary veins radiating from the base. Secondary venation festooned brochidodromous with excostal venation in the outer 1/4 of the lamina. Agrophic veins compound. Spacing of secondary veins increasing toward the base. Angle of secondary veins: one pair of acute basal secondaries. Course of secondary veins mostly zig-zag, due to deflection at origin of tertiaries, curved upward. Intersecondaries weak. Tertiary veins mixed opposite/alternate near mid-vein and random reticulate near margin. Tertiary veins convex and sinuous. Angle of tertiary veins to primary veins obtuse. Angle variability of tertiary veins inconsistent. Quaternary veins regular polygonal reticulate.
