Are the curly structures stamens and what about the circular shell structure in the centre?
Actually, these are remains of the fallen Thumbergia Erecta flowers, quite a feature of this plant. The centre of gravity is far out of the erected flower and if there is extra mass or force on the outer flower such as wind and rain, the flower will detach from the sepals.
There may be some other purposes, evolution would have change this defect if it is detrimental to its survival. Can you figure out?
