The mode of arrangement of leaves on the shoot is called phyllotaxy. It is very important to the plant because the leaves are arranged in such a way that there is maximum exposure of leaves to sunlight with minimum overlapping. It may be alternate, opposite or whorled. In alternate phyllotaxy only one leaf is borne on a node as in China rose. In opposite phyllotaxy two leaves arise in one node as in Calotropis. In whorled phyllotaxy more than two leaves arise in each node as in Nerium.
