The flowers of different species of Loasaceae, shown above, have developed impressive techniques to lure pollinators. Initially, the stamens are hidden in the boat-shaped petals, and upon stimulus by a pollinator, rapidly move towards the center of the flower to present the pollen (e.g. Fig. 1 B, E).
This stunning flower morphology and function allows the plants to avoid pollen loss in the absence of pollinators, and to increase their breeding success.
