The macadamia nut tree is part of the Proteaceae family of flowering plants and is native to the East coast of Australia, though it is also cultivated in Hawaii, New Caledonia and Indonesia now. Named after John Macadam, the macadamia, or macadamia nut, is also commonly called the Queensland nut, Bush nut, Maroochi nut and Bauple nut. Indigenous names for the species include gyndl and jindilli.
The trees can reach as high as 20m and have glossy leaves, but are most famous for producing the macadamia nut. In fact, they are the only Australian native species that is grown on such a large scale for food. As well as being a popular snack, the macadamia nut and macadamia seed oil (which is obtained by cold-pressing the seeds and then putting them through a refining process to produce a mildly-coloured oil that has a faint odour) are commonplace ingredients in the cosmetics industry because of their conditioning benefits.
