Basically Venation means the way the veins and veinlets are arranged on a leaf. One of the two types of venation is Reticulate venation. In this type of venation there is a network of veins which originate from each other. This is found in most dicotyledons. They are commonly called dicots. The dicots are known as reticulate or net because they have this kind of venation. The dicots have their veins in different sizes in cross sections. Some of the leaves which have Reticulate venation are Phaseolus, Anthurium, kalo and Aranda.
