Vedclass · Answer

(D) In $Alstonia$ and $Nerium$,more than two leaves arise at a node,which is known as whorled phyllotaxy.In alternate phyllotaxy,a single leaf arises at each node,as seen in Mustard,China rose,and Sunflower.In opposite phyllotaxy,a pair of leaves arises at each node,lying opposite to each other,as seen in $Calotropis$ and $Guava$ $(Psidium)$.Decussate phyllotaxy is a specific type of opposite phyllotaxy where successive pairs of leaves are at right angles to each other,as seen in $Zinnia$,$Ocimum$,and $Syzygium$.Therefore,the match in option $D$ is incorrect because $Zinnia$ and $Calotropis$ represent different types of opposite phyllotaxy (decussate and superposed,respectively),and the classification provided in the options is inconsistent with standard botanical definitions.
