Dracontium is a genus of flowering plants similar to those of Amorphophallus. It is native to South America, Central America, southern Mexico, and the West Indies.[2][3][4]

Dracontium species can be distinguished from related genera by their inflorescence, which is smaller and unisexual.[5] The plant has a large tuber similar to that of Amorphophallus, but rounder, and with no central and circular scar mark. When Dracontium plants begin to flower, the tuber swells and smoothens.[5][6]
