Due to its odor, which is like the smell of a decomposing animal, the titan arum is called a 'carrion flower', or 'corpse flower', or 'corpse plant'. For the same reason, the name 'corpse flower' is also used for the genus "Rafflesia" which, like the titan arum, grows in the rainforests of Sumatra. The function of the smell is to attract insect pollinators.
