Field Notes
Description:
They are small to large evergreen trees growing to 2–12 m 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.
Habitat:
The two species of edible macadamia readily hybridize, and M. tetraphylla is threatened in the wild due to this. The seed was first described by Europeans south of Brisbane in 1828 by the explorer and botanist Alan Cunningham. One of the locations where wild macadamia trees were originally found was at Mount Bauple near Maryborough in southeast Queensland, Australia. The macadamia seed is the only plant food native to Australia that is produced and exported in any significant quantity
Notes:
The genus is named after John Macadam, a colleague of botanist Ferdinand von Mueller, who first described the genus. Common names include macadamia, macadamia nut, Queensland nut, bush nut, maroochi nut, queen of nuts and bauple nut; Indigenous Australian names include gyndl, jindilli, and boombera.
