1. 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.

2. 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.

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

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