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 philippensis and that of Dr. Domingo Madulid. Thus, the two later names, "R. banahawensis" and "R. banahaw" are synonyms of "R. philippensis". Rafflesia philippensis Rafflesia philippensis is a parasitic plant species of the genus "Rafflesia" that was named by Blanco in his Flora de Filipinas in 1845. "R. philippensis" is known only from a mountain located between the provinces of Laguna and Quezon, Luzon where it was first discovered. Its plant host is "Tetrastigma pisicarpum". This species went unnoticed since its first description by Blanco but was rediscovered in 2003 by members of the Tanggol Kalikasan, a local environment conservation group
