Pollination syndromes are a phenomenon witnessed in many species of plants. Essentially, a pollination syndrome entails a plant possessing traits that perfectly suit it to being pollinated by a particular type or species of pollinator.
A good example is the hummingbird pollination syndrome. These plants are typically red, tubular and have large amounts of dilute nectar.
