Rafflesia - the Largest Flower in the World

The family Rafflesiaceae (in strict sense) consists of three genera - Rafflesia, Rhizanthes and Sapria. These three genera containing over 20 species are confined to South-East Asia region. The genus Rafflesia is claimed to be the largest flower in the world - the flower of Rafflesia arnoldii measuring up to 150 cm in diameter. The three Rafflesiaceae genera (Rafflesia, Rhizanthes and Sapria) have been portrayed in postage stamps:
