The Largest Flower - Rafflesia arnoldii

There are over 20 Rafflesia species in the world. Rafflesia arnoldii is the largest flower species among the Rafflesia species. In fact, R. arnoldii is the largest flower in the world with diameter of the flower measuring up to 150cm. I recently acquired a stamp of Indonesia showing R. arnoldii. The stamp is part of the 10 stamp set of Indonesia-Japan joint issue released on April 15, 2008.
