Rafflesia arnoldii, commonly known as the corpse flower, is the biggest flower on earth. It received its nickname "corpse flower" as a result of its characteristic odour.
There are approximately 17 different species of Rafflesia. Most of these Rafflesia species tend to grow in south-east Asia, mostly in Borneo, and most of them bloom in different shades of red, although some flowers appear pink or brown.
This parasitic plant shows no roots or leaves and radiates the smell of a decaying corpse. This attracts pollinators which in return pollinate the flower. The Rafflesia is the largest flower known on earth, measuring up to 90 cm across and having a weight up to 11 kg. Image: Rafflesia 3 by MaewNam under Creative Common license (CC BY-SA 2.0).
