The iris family contains about 800 species with genera including iris crocus and gladiolus. Irises, named from Greek rainbow, vary in color and are widespread in the north temperate zone. The fleur de lis may derive from the white iris, though some dispute this link, noting ancient use in Indian Egyptian and Etruscan decoration.
The iris uses large petals and a curved stance to guide bees to pollen and nectar. As bees enter to tap nectar they brush the stigma and pollen transfers occur from flowers already visited to ensure cross pollination. Bees exit by the same path, touching a non receptive stigma area to prevent self pollination.
