Stapelia is a genus of about 50 species of clump-forming stem-succulents from southern Africa. The leafless four-angled stems have toothed edges and can be pubescent. Stems grow erect, branching mainly from the base, and develop a reddish color in strong sunlight.
Stapelias have unusual, often large, five-lobed flowers that may be red, purple, or yellow, often with interesting banded patterns. The surface can be brightly polished or matted with hairs. Most species produce a putrid odor of rotting carrion to attract blowflies as pollinators, which explains their popular common name, Carrion Flowers. Stapelia erectiflora and Stapelia flavopurpurea have sweetly scented flowers.
