The Rafflesia Flower is thought to be the biggest flower on the planet. This flower does not grow a stem, leaves, or roots. It is parasitic, growing on a vine in the forests of Borneo and Sumatra.
The Rafflesia is found in southeastern Asia, Indonesia, Malaysia, Thailand and the Philippines. Most species are vulnerable to extinction because of habitat disturbance and host cutting from activities such as land clearing, logging, and ethnobotanical collecting
