Diagnosis

Leaves simple, polymorphic, palmately lobed, rarely unlobed, wide-elliptic to elliptic. In lobate leaves, apices of lateral lobes directed upward or horizontally; apex angle of lobes acute, apex shape straight or acuminate; apex of unlobed leaves acute, straight, or convex. Base angle of lamina obtuse or reflex, rarely acute; base shape rounded or slightly cordate, rarely cuneate. Venation basally actinodromous, with three primaries; lateral primary veins straight, occasionally slightly curved, extending outward or upward; venation of unlobed leaves pinnate. Secondaries up to 8–10 pairs, alternate to subopposite, often irregular, semicraspedodromous or festooned semicraspedodromous, arching upward near the margin; branches from loops terminating in teeth; intersecondaries weak. Tertiaries alternate percurrent to mixed opposite–alternate percurrent. Fourth order veins alternate percurrent. Lamina serrate from base or slightly above. Teeth mostly regularly spaced, small, concave/retroflexed, with more prominent basal side, sinus shape rounded, tooth apex nonspecific.
