Answer» The correct ANSWER is (d) GULMOHAR flower is an example of twisted aestivation To explain I would say: ARRANGEMENT of sepals or petals in a floral bud with respect to the other members of the same whorl is called aestivation. In valvate aestivation, sepals or petals in a whorl just TOUCH each other at the margin, without OVERLAPPING. In twisted aestivation, margin of a sepal overlaps with that of the next one and so on in either clock-wise or counter clock-wise direction. Gulmohar flower is an example of imbricate aestivation.
