Rafflesia arnoldii Rafflesia arnoldii Rafflesia arnoldii, commonly called the corpse lily, is a species of flowering plant in the parasitic genus "Rafflesia". It is noted for producing the largest individual flower on Earth. It has a very strong and unpleasant odour of decaying flesh, earning it the nickname "corpse flower". It is endemic to the rainforests of Sumatra and possibly Borneo. Although there are some plants with larger flowering organs like the titan arum ("Amorphophallus titanum") and talipot palm ("Corypha umbraculifera"), those are technically clusters of many flowers. "Rafflesia arnoldii" (), also called Kerubut (Devil's Betelnut Box), is one of the three
Rafflesia easily in Sumatra and Borneo. Species native to Borneo include "Rafflesia arnoldii", "Rafflesia cantleyi", "Rafflesia hasseltii", "Rafflesia keithii", "Rafflesia kerrii", "Rafflesia pricei", and "Rafflesia tengku-adlinii". "R. arnoldii" boasts the world's largest single bloom. Some endemic Borneon species, such as "R. keithii", begin blooming at night and start to decompose only two to three days later. The time from bud emergence to flowering is six to nine months. Male and female flowers must be open simultaneously for pollination to occur, hence successful pollination and fruit production are quite rare. In addition to habitat loss, these reproductive limitations are contributing factors to
