Theriophonum

Theriophonum is a genus of flowering plants in the family Araceae. It is found only in India and Sri Lanka.^[2][3] The genus is closely related to Typhonium. The only apparent difference between the two is in how many ovules each have and the overall size of the plants. Typhoniums are bigger than Theriophonum.^[4]
