From: The arrangement of lateral veins along the midvein of leaves is not related to leaf phyllotaxis
Lobation and lateral veins of Amur maple (Acer) (panels (a,b)) and Japanese white birch (Betula) (panels (c,d)). Several pairs of symmetrically arranged lateral veins often terminated at the tips of the lobes or serrations of the leaves (red circles in (a,c)). Note that even for the leaves of these species, asymmetrically arranged lateral veins (as shown in (b,d)) were also observed.
