Why are some flowers dark reddish brown with a scent like rotting meat?

Some flowers are dark reddish brown and emit a scent similar to rotting meat to attract specific pollinators, particularly carrion flies and beetles. These plants, such as those in the genus Amorphophallus or Rafflesia, mimic the appearance and odor of decaying flesh to entice these insects, which are naturally drawn to dead animals for reproduction. This adaptation helps ensure effective pollination, as the insects inadvertently transfer pollen while seeking out the deceptive floral offerings.
