Typhonodorum lindleyanum - back side, Andasibe, Madagascar Sometimes called the "Elephant ear plant" but this term is very ambiguous, used to refer to multiple species and even multiple genuses. This particular species,  Typhonodorum lindleyanum, is endemic to Madagascar, like pretty much anything in Madagascar. Not visible on the photo is that it grows in water.

Evolution

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. There isn't fossil evidence to link the two genera so it has been proposed that there once was a genus in Africa from which the two genera had originated. 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.
