The Brazil Nut tree is the only species in the monotypic genus Bertholletia. It is native to the Guianas, Venezuela, Brazil, eastern Colombia, eastern Peru, and eastern Bolivia. The Brazil Nut is a large tree, reaching 50 m tall and with a trunk 1 to 2 in diameter, making it among the largest of trees in the Amazon rainforests. It may live for 500 years or more, and according to some authorities often reaches an age of 1,000 years.

In Brazil, it is illegal to cut down a Brazil Nut tree. As a result, they can be found outside production areas, in the backyards of homes and near roads and streets. The fruit containing nuts is very heavy and rigid, and it poses a serious threat to vehicles and persons passing under the tree.

The fruit takes 14 months to mature after pollination of the flowers. The fruit itself is a large capsule 10 - 15 cm in diameter, resembling a coconut endocarp in size and weighing up to 2 kg. It has a hard, woody shell 8 - 12 mm thick, which contains eight to 24 triangular seeds 4 - 5 cm long (the "Brazil Nuts") packed like the segments of an Orange. Around 20,000 tons of Brazil Nuts are harvested each year, of which Bolivia accounts for about 50%, Brazil 40%, and Peru 10%.
