Carrion flower

Carrion flowers, also known as corpse flowers or stinking flowers, are flowers that emit an odor that smells like rotting flesh. Carrion flowers attract mostly scavenging flies and beetles as pollinators. Some species may trap the insects temporarily to ensure the gathering and transfer of pollen.

Many plants in the genus Amorphophallus (family Araceae) are known as carrion flowers. Titan arum (Amorphophallus titanum), which has the world's largest flower head, is also called "carrion flower". Rather than a single flower, the titan arum presents an inflorescence or compound flower composed of a spadix or stalk of small and anatomically reduced male and female flowers, surrounded by a spathe that resembles a single giant petal. This plant has a mechanism to heat up the spadix enhancing the emission of the strong odor of decaying meat to attract its pollinators, carrion-eating beetles and "flesh flies" (family Sarcophagidae). It was first discovered in 1878 in Sumatra.

Flowers of plants in the genus Rafflesia (family Rafflesiaceae) emit an odor similar to that of decaying meat. This odor attracts the flies that pollinate the plant. The world's largest single bloom is R. arnoldii. This rare flower is found in the rainforests of Borneo and Sumatra. It can grow to be 3 feet across and weigh up to 15 pounds. R. arnoldii is a parasitic plant on Tetrastigma vine, which grows only in primary rainforests. It has no visible leaves, roots, or stem. It does not photosynthesize, but rather uses the host plant to obtain water and nutrients.
