Rafflesia is the world's largest, the heaviest, the rarest and the one of the most stinkiest flowers in the world. It grows to 1 meter wide and weighs about 10 kgs. Rafflesia is native to the rainforests of Sumatra and Borneo in the Indonesian Archipelago. Rafflesia is a parasitic plant without any leaves, stems and roots (It has only nutrient-absorbing threads to absorb nutrients from the host on which it lives).
Why It Is Endangered
It is found in a very small part of the world. It is totally dependent on other plants because it is a parasite ,and it lives on the slopes of mountains in the tropical rain forests.
