Rafflesia arnoldii: This parasitic plant develops the world's largest bloom that can grow over three feet across. The flower is a fleshy color, with spots that make it look like a teenager's acne-ridden skin. It smells bad and has a hole in the center that holds six or seven quarts of water. The plant has no leaves, stems or roots.

Hydnora africana, an unusual flesh-colored, parasitic flower that attacks the nearby roots of shrubby in arid deserts of South Africa. The putrid-smelling blossom attracts herds of carrion beetles.

Dracunculus vulgaris: smells like rotting flesh, and has a burgundy-colored, leaf-like flower that projects a slender, black appendage.

Amorphophallus: means, literally, "shapeless penis." The name comes from the shape of the erect black spadix.
