Rafflesia arnoldii of Sumatra and Borneo. To help counter the over-collection of this rare plant, residents that have "Rafflesia" on their private property are encouraged to save the flowers and charge a small fee to see them. 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
Rafflesia tuan-mudae flower are flies. All "Rafflesia" flowers emit a rotting meat stench attracting pollinators, although the smell of "R. tuan-mudae" is comparatively mild. However, they are no less effective at attracting these flies, upon whose back pollen is deposited. Male and female flowers can only be identified by fingering under the central disk for the anthers. However, visitors are encouraged not to touch or handle the buds in particular, as they are fragile and may die. In Sarawak, one of the easiest locations to see "R. tuan-mudae" is at Gunung Gading National Park, at the park headquarters or near Waterfall 7.
