One of them (in the center) is already growing tube which will be supplied semen. Pollen from plants of other species (yellow and green) got here by mistake; genetic mechanism of protection will not allow her to participate in fertilization. (Martin Oeggerli)

Pollen flytrap (Dionaea muscipula) more than 15 times larger pollen forget-me: thus, the direct relationship between the size of the flower and the pollen grains do not. (Martin Oeggerli)

Sticky pollen levkofilluma (family Proteaceae) is transferred to the animals. (Martin Oeggerli)
