False-colour scanning electron micrograph of the reproductive structures of a flower of the chickweed, Stellaria media. The bulbous carpel, with the short-stalked female stigmas emerging from it, is at lower centre. Two of the long- stalked male anthers have closed in to contact the stigmas; a third remains separate at right, its tip covered with pollen. The droplets in the bottom right & left corners (blue) are nectar to attract pollinating insects. Chickweed is also self-pollinating. The round pollen grains on the stigmas show that this flower has been pollinated, probably by the anthers in contact with the stigmas. Magnification: x12 at 6x4.5cm size.
