A flower with two petals and one sepal removed to show the corolla interior. A pollinator entering though one of the five circular holes immediately touches the stigma -- located at the same level -- with pollen from the previously visited flower. When the pollinator exits the flower, now with the flower's own pollen, a bell-shaped ovary shields the five-lobed stigma below. This flower structure appears to encourage cross-pollination.
