context_page_description: Rafflesia arnoldii, commonly called the corpse lily or stinking 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 Borneo. Although there are some plants with larger flowering organs like the titan arum and talipot palm, those are technically clusters of many flowers.
  Rafflesia arnoldii, also called kerubut, is one of the three national flowers in Indonesia, the other two being the white jasmine and moon orchid. It was officially recognized as a national "rare flower" in Presidential Decree No. 4 in 1993.
context_section_description: The flower of Rafflesia arnoldii grows to a diameter of around one meter (3.3 feet), but the greatest measurement from a reliable source is 105 centimeters (3.44 feet) for one at Palupah Nature Reserve near Bukittinggi, Sumatra measured by Prof. Syabuddin of Andalas University. R. arnoldi weighs up to 11 kilograms (24 lb). These flowers emerge from very large, cabbage-like, maroon or magenta buds typically about 30 cm (12 in) wide, but the largest (and the largest flower bud ever recorded) found at Mount Sago, Sumatra in May 1956 was 43 cm (17 in) in diameter.  It lives as a parasite on several vines of the genus Tetrastigma, which grow only in primary (undisturbed) rainforests. Rafflesia lacks any observable leaves, stems or even roots, yet is still considered a vascular plant. Similar to fungi, individuals grow as thread-like strands of tissue completely embedded within and in intimate contact with surrounding host cells from which nutrients and water are obtained. This plant produces no leaves, stems or roots and does not have chlorophyll. It can only be seen outside the host plant when it is ready to reproduce. Perhaps the only part of Rafflesia that is identifiable as distinctly plant-like are the flowers, though even these are unusual since they attain massive proportions, have a reddish-brown coloration, and stink of rotting flesh. This scent attracts insects such as flies which then pollinate the rare plant. It is not to be confused with the titan arum, Amorphophallus titanum, which is also commonly referred to as the "corpse flower" because of its repulsive odor.
