Rafflesia Park where the flowers are numbered and monitored by the park rangers. "Rafflesia" are also remarkable for showing a large horizontal transfer of genes from their host plants. This is well known among bacteria, but not higher organisms. The name "corpse flower" applied to "Rafflesia" can be confusing because this common name also refers to the titan arum ("Amorphophallus titanum") of the family Araceae. Moreover, because "Amorphophallus" has the world's largest unbranched inflorescence, it is sometimes mistakenly credited as having the world's largest flower.

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
