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.

They rely entirely on their host plants for both water and nutrients, and only then emerge as flowers from the roots or lower stems of the host plants. Rafflesiaceae flowers mimic rotting carcasses in scent, color, and texture to attract their pollinators, carrion flies. For this reason, some flowers
