(AIIMS-2018)

Solution

Valvate petals are close to each other and do not overlap. In twisted, petals overlap each other regularly. In imbricate, there are five petals, arranged in such a way that one petal is completely external and one is completely internal. In quincuncial, two out of five petals are completely external and remaining $3$ are partially external and partially internal. In vexillary, the posterior petal overlaps the two smaller lateral petals and later in turn overlap the two anterior petals.
