Venation is the arrangement of veins in lamina of the leaf. Two types of venation are reticulate venation and parallel venation.
(i) Reticulate Venation: When the veins are irregularly distributed to form a channel, it is known as reticulate Venation. Taproots are found in plants which have reticulate venation in their leaves. It can be seen tulsi, coriander (dhania), china rose, hibiscus, mango, etc.
(ii) Parallel Venation: When the veins are parallel and do not form a network, it is known as parallel Venation.Fibrous roots are found in plants which have parallel venation in their leaves. It can be seen in wheat, maize, grass, banana, bamboo, etc
