Brazil nut (Bertholletia excelsa) refers to a South American tree of the monotypic genus Bertholletia in the family Lecythidaceae as well as the tree's commercially-harvested edible seeds. It is one of the largest and longest-lived trees in the Amazon rainforest. The fruit and its nutshell – containing the edible nut – are relatively large and weigh as much as 2 kg (4.4 lb) in total. As food, Brazil nuts are notable for diverse content of micronutrients, especially a high amount of selenium. The wood of the Brazil nut tree is prized for its quality in carpentry, flooring, and heavy construction.
