Phyllotaxy
is the arrangement of leaves on the stem in plants. It is of 3 types,

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.'
