How imbricate aestivation affects pollination?

The pattern of imbricate aestivation can influence how flower segments open, how pollen is presented, and how pollinators access the flower. Overlapping petals can protect reproductive organs until a pollinator arrives, then open in a controlled way. They may guide pollinator movement, regulate timing of opening and closing, and help ensure that pollen release and stigma contact coincide with pollinator visit. Therefore the aestivation pattern indirectly influences pollination efficiency, pollen protection, and flower opening mechanics.
