Treculia is a genus of trees in the plant family Moraceae that is native to west and central Africa and Madagascar. The best-known member of the genus, Treculia africana, commonly known as the African breadfruit, is used as a food plant.
The fruits are hard and fibrous, can be the size of a volleyball and weight up to 8.5 kg. Chimpanzees have been observed to use tools to break the fruits into small pieces that they can eat.
