The Cumaru (Dipteryx odorata), also known as the Tonka bean tree, is a tree native to the Amazon rainforest, particularly associated with upland forests. It is a large tree that can reach approximately 30 meters in height, with a straight trunk and broad crown.

Its fruits contain an aromatic seed, internationally known as the tonka bean, valued for its distinctive fragrance. The species also has ecological importance, being visited by native bees, while its fruits and seeds can be dispersed by wildlife, including bats.

Its wood is heavy, strong and durable, giving the species economic and cultural importance in the Amazon region.

Curiosity: the scientific name odorata refers to the strong fragrance of its seeds.
