The Rafflesia arnoldii is a parasitic plant genus Rafflesia , found in the rainforests of Indonesia (mainly in Sumatra and Borneo ) and in the jungles of Southeast Asia, developing the world’s largest flower. It was discovered in Sumatra in 1818 by Thomas Stamford Raffles and Joseph Arnold.
- The flowers can reach up to three feet in diameter and can weigh up to 11 kilograms, thus becoming the largest in the world. These fleshy flowers reddish or orange and five lobes that remain open between five and seven days. As with other plants with large blooms, they only occur every few years.
- The flowers, which emit a strong foul odor (similar to rotten meat), are capable of emitting heat. It is believed that both mechanisms are used to mimic the heat and the smell of a dead animal and attract the attention of carrion flies, which are insects that pollinate it.
- The plant has no leaves, shoots and roots (his only visible flower) and therefore does not perform photosynthesis .
- It is a parasitic plant trees, grow on its roots, from where it obtains nutrients.
- Their vegetative organs are reduced to a cellular network of fibers that are mostly between the tissues of the host plant or forming a body called rhizomatoide twisted underground.
