The Rafflesia Arnoldii, also known as the stinking corpse lily, is the world’s largest individual flower and truly a wonder of the plant kingdom. It has been called the giant panda of the plant world. It has been called the “giant panda of the plant world” because this rare and endangered species only occurs in the rain forests of Sumatra and Borneo in the Malay Archipelago.
Rafflesia Arnoldii Is In The Parasitic Family
Rafflesia arnoldii is in the parasitic family, and therefore does not have any roots, stems or leaves. Instead, it grows within the woody stems of the vine Tetrastigma, a relative of the grape. Occasionally a large Rafflesia Arnoldii flower bud, resembling a pale orange cabbage, breaks through the bark of the host vine and expands into an enormous blossom that’s up to 3 feet in diameter, and weighs up to 25 pounds!
The gigantic unisexual flower has five fleshy red lobes (sepals) spattered with raised white spots. With an odor reminiscent of a stinking corpse, (thus it’s common name, the Stinking Corpse Lily) the blossom attracts carrion beetles and flies which shuttle the pollen from male to female flowers.
Up To Four Million Seeds
A single female flower may produce up to four million seeds which are dispersed by a variety of animals, from ants, tree shrews and squirrels, to the feet of wild pigs and Asian elephants. If a seed becomes lodged in a moist crevice on its host vine, it germinates and penetrates the host tissue where it proliferates into a network of microscopic filaments of cells.
These fungus-like networks of vascular tissue eventually give rise to a mammoth blossom that pushes out through the host stem, making Rafflesia one of the most intriguing and unusual plants on earth. The chances of a seed finding a host vine are slim, and massive deforestation has further decreased the odds of this remarkable event. Recently the governments of Indonesia and Malaysia have begun to recognize the marketable curiosity value of this plant and ecological preserves are being established.
