Identify the order where plants show alternate, opposite and whorled phyllotaxy.
China Rose, Calotropis and Nerium
Phyllotaxy is the arrangement of leaves on the stem in plants. It is of 3 types, namely alternate, opposite and whorled. In alternate type, leaf arises at each node in an alternate manner. Examples include china rose, sunflower, grass. In opposite type, pair of leaves arise at each node and are opposite to each other. Examples include Calotropis, guava. In whorled type, more than two leaves arise at a node and form a whorl. For example Alstonia, Nerium. Thus, the correct answer is 'China Rose, Calotropis and Nerium.'
