Brazil nut, Bertholletia excelsa, is a tropical evergreen in the family Lecythidaceae grown for its edible seeds (nuts). The brazil nut tree is very large with a long straight trunk which is 1–2 m (3.3–6.6 ft) in diameter. The
tree only branches in the upper regions and the long branches are covered in large, leathery, oblong shaped leaves which form a spreading canopy. The tree produces large, pale yellow or greenish flowers and a round fruit which
is approximately 15 cm (6 in) in diameter. The fruit has a thick hard shell and contains 18 to 24 angular seeds (nuts). The large edible kernel is protected by a thin, woody shell which has a wrinkled appearance. Brazil nut
trees can reach a height of 25–56 m (82–184 ft) and can live for well over 500 years. Brazil nut may also be referred to as cream nut or butter nut and originates from the Amazonian rainforest.
