How the corpse flower came to be so weird

  • The titan arum, also known as the corpse plant, blooms with a large spike and red spathe, emits a rotting flesh smell, and the bloom lasts about 36 hours, occurring every 7+ years.
  • It attracts scientific and public interest due to its unique traits, including evolutionary mimicry to attract carrion insects as pollinators with appearance and sulfur-based compounds like putrescine.
  • The plant generates heat by metabolizing starch into sugar and releasing energy as warmth to disperse its odor, enhancing pollination chances.
  • Endangered with fewer than 1,000 wild plants, its odor emissions can be affected by air pollution, potentially reducing pollinator visits.
  • Evolutionarily, it shows a mismatch: gigantic inflorescence but dwarfed individual flowers, with small flowers ancestral and leading to selection for larger overall blooms rather than bigger flowers.
