Determined to be pollinated
Many orchids have distinct smells — from the notoriously bad-smelling Bulbophyllum species, including the peppery Bulbophyllum grandiflorum shown here, to sweet-smelling vanilla orchids. (That's right! Vanilla comes from an orchid plant.) Smells of rotting flesh attract flies, while pleasant scents clue in pollinators to sources of nectar.
