Venation refers to the pattern of distribution of the veins in the lamina of a leaf. Two types of venation are found in plants:

(a) Reticulate: The veins are irregularly distributed to form a network. This type of venation is a characteristic of dicots such as peepal and mango.

(b) Parallel: In this type of venation, the veins run parallel to each other and no network is formed. This type of venation is a characteristic of monocots such as wheat, rice, maize and grass.
