Where does the rafflesia flower grow?

Rafflesia arnoldii produces the largest single flower in the world, up to about 1 metre across and weighing up to around 10 kilograms. The plant is a parasite with no leaves, stems or roots of its own, living inside Tetrastigma vines. It gives off a smell of rotting meat, earning it the name 'corpse flower', which attracts carrion flies to pollinate it. A flower bud can take many months to develop but blooms for only about five to seven days. The genus is named after Sir Stamford Raffles, founder of modern Singapore, who was on the 1818 expedition that brought it to Western attention.
