Venation

The arrangement of veins and the veinlets in the lamina of leaf is termed as venation

Venation

When the veinlets form a network, the venation is termed as reticulate that possesses in dicotyledonous plants

When the veins run parallel to each other within a lamina, the venation is termed as parallel is the characteristic of most monocotyledons.
