Term Definition
Leaf venation actinodromous Referring to a type of leaf venation in which three or more primary veins diverge radially from a single point either at (basal actinodromous) or above (suprabasal actinodrmous) the point of attachment of the petiole. The primary veins can either converge at the apex (perfect actinodromous) or not converge at the apex (imperfect actinodromous). Based on Hickey, 1973.
