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]
