The arrangement of veins and veinlets on the lamina of a leaf is called Venation. It is two types – Reticulate venation and Parallel venation.
- Reticulate venation: The veins and veinlets of some leaves are irregularly distributed over the entire lamina and forming a net like network is called Reticulate venation. The leaves of peepal, guva and mango are the some example of this venation.
- Parallel venation: The veins of some leaves are run parallel to each other is called the Parallel venation. The leaves of banana, wheat, grass etc are the some example of this kind of venation.
