Charles Darwin, author of On the Origin of Species, loved flowers. He wrote to the English botanist Joseph Dalton Hooker: “I never was more interested in any subject in all my life than in this of Orchids.” The morphological structure of orchid flowers is simple—three sepals, three petals, and a “column” that contains the reproductive parts—but these flowers lure insect pollinators by many clever mechanisms, such as color, mimicry, scent, deception, and traps.
