Explanation
Solution
In alternate (or spiral) phyllotaxy, only one leaf is borne on a node and the leaves of the adjacent nodes roughly lie towards the opposite sides (e.g., Hibiscus). In opposite phyllotaxy, two leaves are borne on the opposite sides of a single node, e.g., guava in whorled or verticillate phyllotaxy, three (e.g., Nerium) or more than three (e.g., Alstonia) leaves develop from a single node.
