Leaf commonly trilobate, rarely bilobate or unlobed; base ranging from acute to obtuse and tending towards cuneate, with the basalmost portion of the lamina decurrent on the petiole; margin entire; apex of lobes acute to rounded; unlobed leaves broad elliptic to obovate, with rounded apex. Primary venation basal to suprabasal actinodromous in 3-lobed leaves, pinnate in unlobed leaves; midvein moderate; lateral primary veins similar to midvein in thickness, at lower angle than superadjacent secondary veins and tending to be recurved, commonly decurrent on midvein, producing one to three festooned brochidodromous external branches. Secondary venation festooned brochidodromous; secondary veins thin or moderate relative to primary veins, three to six pairs along midvein, with one pair of basilaminar secondary veins present in all leaves, alternate, moderate acute, straight to apically curved, tending to be festooned brochidodromous except near sinuses. Tertiary venation reticulate; tertiary veins thin relative to secondary veins, opposite to alternate, closely but somewhat irregularly spaced, originating at acute to right angles. Quaternary venation intergrading with tertiary veins, generally unbranched; quaternary veins opposite to alternate, non-orthogonal, enclosing somewhat elongate, 4-sided regions. Quinternary venation highly irregular, both ramified and reticulate, arising both from thick lateral branches of the quaternary veins and from the sides of lower order veins; quinternary veins weak, curved, often producing branches to form an open venation. Areolation poorly developed. Marginal venation consisting of a thin fimbrial vein.
