20. Titan Arum
The Titan Arum (Amorphophallus titanum) is a massive flower which can reach over 3m (10ft) in height. It is only found on Sumatra. Its odor is reminiscent of a rotting corpse, just like the corpse flower. The odor attracts insects which would normally feed on dead animals or lay their eggs in decaying flesh. The potency of the smell increases during the late evening until the middle of the night.
