Amorphophallus titanum (from Ancient Greek amorphos, "without form, misshapen" + phallos, "phallus", and titan, "giant"), known as the titan arum, 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 like the smell of a rotting animal, 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 can be translated as corpse, cadaver, or carrion). 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, Indonesia and Malaysian Borneo in Sabah and Sarawak.
Amorphophallus titanum is native solely to western Sumatra, where it grows in openings in rainforests on limestone hills. Some claims of appearance in Cabanatuan City, Philippines, have not yet been confirmed. However, the plant is cultivated by botanic gardens and private collectors around the world.
The titan arum's inflorescence can reach over 3 metres (10 ft) in height. Like the related cuckoo pint and calla lily, it consists of a fragrant spadix of flowers wrapped by a spathe, which looks like a large petal. In the case of the titan arum, the spathe is a deep green on the outside and dark burgundy red on the inside, with a deeply furrowed texture. The spadix is hollow and resembles a large loaf of French bread. Near the bottom of the spadix, hidden from view inside the sheath of the spathe, the spadix bears two rings of small flowers. The upper ring bears the male flowers, the lower ring is spangled with bright red-orange carpels. The "fragrance" of the titan arum resembles rotting meat, attracting carrion-eating beetles and flesh flies (family Sarcophagidae) that pollinate it. The inflorescence's deep red color and texture contribute to the illusion that the spathe is a piece of meat. During bloom, the tip of the spadix is approximately human body temperature, which helps the perfume volatilize; this heat is also believed to assist in the illusion that attracts carcass-eating insects.
