Typhonodorum is a monotypic genus of flowering plants in the family Araceae.

The genus is native to Madagascar, the Comores, Zanzibar, Réunion and Mauritius.

[1] This genus is believed to be closely related to Peltandra even though Peltandra is only found in North America and there don't appear to exist closely related genera in the African mainland.

The African mainland genus spread to North America and to Madagascar 50 million years ago before it broke off.

Then the African genus became extinct and the North American and Madagascan genera remained.
