- Diagnosis
- Leaves simple, palmately lobed. Lamina symmetrical
or asymmetrical with medial or base width asymmetry. Petiole
long, slender. Base angle of lamina obtuse, base shape convex,
cuneate, rounded or slightly cordate. Apices of lateral lobes
directed upwards or horizontally; apex angle of lobes acute, apex
shape straight. Deep sinuses between lobes angular or rounded
in shape, untoothed. Leaf margin serrate from the base, frequently
leaf base partly untoothed. Teeth irregularly spaced,
concave/retroflexed, sinus shape rounded, tooth apex nonspecific.
Venation basal or suprabasal actinodromous, with three
to four primary veins; lateral primary veins extend outward or
upward. Secondaries up to 6–10 pairs, alternate to sub-opposite,
rarely opposite, often irregular, semicraspedodromous or festooned
semicraspedodromous, arching upward near the margin;
intersecondaries weak. Tertiary veins alternate percurrent or
mixed opposite–alternate percurrent. Fourth-order veins alternate
percurrent.
