The Rafflesia flower is a genus of parasitic flowering plants found in Southeast Asia, including 28 species. It was first discovered in 1797 on Java by a French explorer but officially named in 1818 after British explorer Sir Stamford Raffles discovered a species on Sumatra. The Rafflesia is famous for having the largest single flower in the world, with some species reaching over 1 meter wide and weighing over 6 kg.
