Macadamia nut

Macadamia is a genus of four species of trees in the flowering plant family Proteaceae. They are indigenous to Australia, native to northeastern New South Wales and central and southeastern Queensland specifically. Two species of the genus are commercially important for their fruit, the macadamia nut /ˌmækəˈdeɪmiə/ . Global production in 2015 was 160,000 tonnes (180,000 short tons). Other names include Queensland nut, bush nut, maroochi nut, bauple nut and, in the US, they are also known as Hawaii nut. It was an important source of bushfood for the Aboriginal peoples. The nut was first commercially produced on a wide scale in Hawaii, where Australian seeds were introduced in the 1880s, and for some time, they were the world's largest producer. South Africa has been the world's largest producer of the macadamia since the 2010s.
