Corpse Flower: The Living Dead

Today’s plant costume is an odiferous disguise instead of a visual one. Its common name is also appropriate for the Halloween season- The Corpse Flower. It only pretends to be dead by giving off a rank odor of rotting flesh when it blooms. Again the reason is pollination. This horrible smell to us calls to every beetle and fly around that supper’s on. While they root around in the tight dark spaces of the bloom trying to find a decent place to feed and lay their eggs, they become covered in pollen. These pollen-covered insects then fly off to another bloom to pollinate another plant.

This species, Amorphophallus titanum*, is also a superphotosynthesizer in the plant world. As you may have noticed from the pictures and videos, the blooms can be as large as 10 feet tall. This makes the corpse flower the world’s largest inflorescence. Notice I didn’t say flower. Ah, botanical anatomy semantics! The images may look like a giant flower with burgundy petals surrounding a central stigma on steroids. Not so. The ‘petal’ portion of the flower is actually a bract structure called a spathe (plant biology word of the day). The tall central feature is called a spadix (bonus plant biology word of the day), and it is this structure on which the true flowers of the plant (separate male and female flowers) are arranged. The entirety of this plant reproductive structure is the inflorescence and there isn’t a bigger one in the plant world. The world’s record for a corpse flower bloom is nearly 11 feet tall. After flowering, the plant then makes the world’s largest leaf structure. It may look a tree in its own right, but developmentally, it’s just a compound leaf.
