What's the sources of Macadamia Oil?
Macadamia is a genus of four species of trees indigenous to Australia and constituting part of the plant family Proteaceae.They are native to north eastern New South Wales and central and south eastern Queensland. The tree is commercially important for its fruit, the macadamia nut or simply Macadamia Oil. Other names include Queensland nut, bush nut, maroochi nut, bauple nut, and Hawaii nut. InAustralian Aboriginal languages, the fruit is known by names such as bauple, gyndl, jindilli,and boombera.
Previously, more species, with disjunct distributions, were named as members of this genus Macadamia.Genetics and morphological studies more recently published in 2008 show they have separated from this Macadamia Oil, correlating less closely than thought from earlier morphological studies.The species previously named in this Macadamia genus may still be referred to overall by the descriptive, non-scientific name of Macadamia Oil; their disjunct distributions and current scientific names are:
Macadamia Oil species grow as small to large evergreen trees 2–12 m (6.6–39.4 ft) tall. The leaves are arranged in whorls of three to six, lanceolate to obovate or elliptical in shape, 6–30 cm long and 2–13 cm broad, with an entire or spiny-serrated margin. The flowers are produced in a long, slender, simple raceme 5–30 cm long, the individual flowers 10–15 mm long, white to pink or purple, with four tepals. The fruit is a very hard, woody, globose follicle with a pointed apex, containing one or two seeds.
