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 verrucosa the plant. "Rafflesia verrucosa" has very distinctive raised warts on its perigone lobes and diaphragm. The warts are non-uniform in shape or size. The warts extend to the diaphragm rim of the plant; this characteristic is unique to "R. verrucosa", while all other "Rafflesia" species lack warts on their diaphragms. Another unique characteristic of "R. verrucosa" is the anastomosing plate-like processes on the plants disk. The hair like ramenta are longer (7 mm) when compared to other small "Rafflesia". Compared to other smaller-sized "Rafflesia", the anther number of "R. verrucosa" is much greater (20-21). The anthers size and disk size
