This member of the
Araceae family
was given this name by Dan Henry Nicolson in 1977. It is found in
Andaman Islands, Assam, Bangladesh, Borneo, Cambodia, China, East
Himalaya, Hainan, India, Indonesia, Laos, Lesser Sunda Islands, Malaya,
Maluku, Myanmar, New Guinea, Philippines, Sri Lanka, Taiwan, Thailand
and Vietnam. It might have been introduced to some of these, and for
sure to Comoros, Cook Islands, Fiji, Madagascar, Marquesas, New
Caledonia, Niue, Samoa, Seychelles, Society Islands, Trinidad-Tobago,
Vanuatu. It is growing in a rich soil with plenty of water and not that
much sun if any. The corm can grow to
20-30 centimetres in diameter and 25 Kg, the entire plant
to 200 centimetres in height. The flowers are deep purple and smelly for a short
period. The female flowers open at first.
An interesting technique used in Indonesia is to dig up the tuber after
one year and then replant it upside down. This stimulates the lateral
buds into growth and increases the overall size of the tuber
The genera name from ancient
Greek amorphos, 'without form, misshapen' and phallos,
'penis',
referring to the shape of the prominent spadix. The species name
from Latin: paeonii; 'Peony-like' (genus Paeonia) and folius;
'foliage'. |
