위키 설명
Amorphophallus titanum, the titan arum, is a flowering plant in the family Araceae. It has the largest unbranched inflorescence in the world. The inflorescence of the talipot palm, Corypha umbraculifera, is larger, but it is branched rather than unbranched. A. titanum is endemic to rainforests on the Indonesian island of Sumatra.
Due to its odor, like that of a rotting corpse, the titan arum is characterized as a carrion flower, and is also known as the corpse flower or corpse plant as translated from the original Indonesian word bunga bangkai (bunga means flower, while bangkai can be translated as corpse, cadaver, or carrion).
The titan arum's berries arrange in a regular cylindrical form that resembles the packing of spheres inside a cylindrical confinement. Those structures are also called columnar structures or crystals.
Etymology
A. titanum derives its name from Ancient Greek (ἄμορφος amorphos, "without form, misshapen" + φαλλός phallos, "phallus", and Τιτάν Titan, "titan, giant").[2]
Description
Its corm is the largest known, typically weighing around 50 kg (110 lb).[3] When a specimen at the Princess of Wales Conservatory, Kew Gardens, was repotted after its dormant period, the weight was recorded as 91 kg (201 lb). [4] In 2006, a corm in the Botanical Garden of Bonn, Germany, was recorded at 117 kg (258 lb),[5] and an A. titanum grown in Gilford, New Hampshire by Dr. Louis Ricciardiello in 2010 weighed 138 kg (305 lb).[6][7] However, the current record is held by a corm grown at the Royal Botanic Garden Edinburgh, weighing 153.9 kg (339 lb) after 7 years' growth from an initial corm the size of an orange.[8] The tallest documented inflorescence was recorded at the Botanical Gardens Bonn (Germany) in May 2013 and reached 3.20 m.[9][10]
Flowers
The titan arum's inflorescence can reach over 3 m (10 ft) in height.[11][9] 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 almost hollow and resembles a large baguette. 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 odor ("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 roughly human body temperature, which helps the perfume volatilize; this heat is also believed to assist in the illusion that attracts carcass-eating insects.[9]
Both male and female flowers grow in the same inflorescence. The female flowers open first, then a day or two following, the male flowers open. This usually prevents the flower from self-pollinating.
After the flower dies back, a single leaf, which reaches the size of a small tree, grows from the underground corm. The leaf grows on a somewhat green stalk that branches into three sections at the top, each containing many leaflets. The leaf structure can reach up to 6 m (20 ft) tall and 5 m (16 ft) across. The stalk, or petiole bearing the leaf can be up to 15-16 inches (38-41 centimeters) thick at soil level and still 12-13 inches (30-32 cm) at breast height (D.B.H.).[12] Each year, the old leaf dies and a new one grows in its place. When the corm has stored enough energy, it becomes dormant for about four months. Then the process repeats.
Distribution
A. titanum is native solely to western Sumatra,[11] where it grows in openings in rainforests on limestone hills.[13] However, the plant is cultivated by botanical gardens and a few private collectors around the world.[11]
