The spathe and spadix of Amorphophallus titanum by Kandis Elliot.

What is an Aroid?
Aroid is the common name for members of the Araceae family of plants, sometimes known as the Philodendron or Arum family. The occasionally beautiful and often bizarre combination of spathe and spadix called the inflorescence, sometimes referred to as a "flower", is a distinguishing feature of all aroids.
