Schaller and collaborators then identified what kicks off the corpse flower’s thermogenesis, as well as the specific chemical culprits behind its smell. RNA analysis detected the presence of enzymes called alternative oxidases that grew in number during Morphy’s flowering, as well as genes necessary in the metabolization and transport of sulfur.

When it blooms, this stinky flower releases chemicals that smell like rotting flesh to attact pollinators, such as carrion beetles and flies.

The corpse flower is infamous for its rare blooms and its signature odor, which mimics the stench of rotting flesh.
