Drakaea glyptodon: an orchid. It is the color of, and smells like, raw meat. Pollinated by male wasps.
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.
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.
Welwitschia mirabilis consists of only two leaves and a stem with roots. Its two leaves continue to grow until they resemble an alien life form. The stem gets thicker rather than higher, although this plant can grow to be almost six feet high and twenty-four feet wide. Its estimated lifespan is 400 to 1500 years. Mirabilis grows in Namibia, and is thought to be a relic of the Jurassic period.
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.
