Titan arums are true giants amongst flowering plants: the circumference of their huge flowers can be over three metres and they stand three metres high and the single leaf grows to the size of a small tree. Their smell, likened to rotting meat, is so bad it led to the common name 'corpse flower'. Both the 'fragance' and the flower's meat-colouration attract pollinators - carrion flies and beetles.
The titan arum or Amorphophallus titanum (from Ancient Greek amorphos, "without form, misshapen" + phallos, "phallus", and titan, "giant" [Giant Misshapen Penis]) is a flowering plant with the largest unbranched inflorescence in the world. The titan arum's inflorescence is not as large as that of the Talipot palm, Corypha umbraculifera, but the inflorescence of the Talipot palm is branched rather than unbranched.
Due to its odor, which is reminiscent of the smell of a decomposing mammal, the titan arum is characterized as a carrion flower, and is also known as the "corpse flower", or "corpse plant" (Indonesian: bunga bangkai – bunga means flower, while bangkai means corpse or cadaver). For the same reason, the title "corpse flower" is also attributed to the genus Rafflesia which, like the titan arum, grows in the rainforests of Sumatra.
