Rafflesia arnoldii which then pollinate the rare plant. It is not to be confused with the titan arum, "Amorphophallus titanum", which is also commonly referred to as the "corpse flower" because of its repulsive odor. "Rafflesia arnoldii" is rare and fairly hard to locate. It is especially difficult to locate the flower in forests, as the buds take many months to develop and the flower lasts for just a few days.

The talipot palm bears the largest inflorescence of any plant, long, consisting of one to several million small flowers borne on a branched stalk that forms at the top of the trunk (the titan arum, "Amorphophallus titanum", from the family Araceae, has the largest unbranched inflorescence, and the species "Rafflesia arnoldii" has the world's largest single flower). The talipot palm is monocarpic, flowering only once, when it is 30 to 80 years old. It takes about a year for the fruit to mature, producing thousands of round, yellow-green fruit in
