The world's biggest flowers are in
danger: the mottled orange-brown & white parasite Rafflesia arnoldii. The plant attaches itself to cissus vines in the jungles of Southeast Asia. It's blooms are as much as 3 ft across with petals ¾ of an inch thick and weigh up to 36 lb. Rafflesias produce a corpse-like sent to attract carrying eating insects
for pollination; they are also known as corpse lilies. Many of the 42 species of Rafflesia are endangered due to habitat loss & poaching. It's buds are harvested for medicine. Like other parasitic plants, it can't be framed. Even in the wild, it doesn't succeed at being pollinated that often.
