Rafflesia arnoldii, “monster flower” of Indonesia. The world's largest flower (the size of an automobile tire) takes several months to develop the bud while the parasitic plant obtains nutrients within the woody tissue of a Tetrastigma vine. <~-- A single female flower may produce up to 4 million seeds. The flower attracts carrion flies as pollinators with an odor reminiscent of a decaying corpse.
