Flora : Rafflesia Arnoldii

Rafflesia arnoldii 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 horrible odour of decaying flesh, earning it the nickname "corpse flower". It is endemic to the rainforests of Sumatra and possibly Borneo.Although there are some plants with larger flowering organs like the titan arum (Amorphophallus titanum) and talipot palm (Corypha umbraculifera), those are technically clusters of many flowers.

Rafflesia Arnoldi is known as the biggest flower in the world. The name is derived from the British governor General, Sir Thomas Stamford Rafflesia , who gave attention to the botanical garden in Bogor.
The Rafflesia Arnoldi consists of two parts: the stick-like part which grows in the middle and the petals around and below it. It is unusual flower because of its large size. The flower can be 1 meter in diameter and 1.40 meters in height.
The Rafflesia plant begins to flower in its tenth year. It blooms three or four times a year. Before it begins to flower, the leaves and the stem become dry and look dead, but the main root in the ground is still alive. When it blooms, it has an unpleasant smell which attract insect. But when they touch the bottom part, they die.
