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".

Rafflesia lobata diaphragm curves inward and may be 3- or 6-lobed. Note the 6-lobed flower also has 6 perigone lobes. It remains to be seen whether flower merousity has phylogenetic significance that should be taxonomically recognized. Some populations of R. manillana, such as one at Bolos Point, Cagayan Valley, Luzon, also have flowers with lobed, outwardly curving diaphragms. The name of the species was derived from its distinctive lobed diaphragm. The first population of "R. lobata" was discovered by the local conservation group studying Philippine Spotted Deer ("Cervus alfredi").
