It is believed that long before Australia was mapped by European explorers, Aboriginal people would congregate on the eastern slopes of Australia's Great Dividing Range to feed on the seed of two evergreen trees, one of which they called 'Kindal Kindal'.
In the 1850's these trees were noticed by a British botanist and the Director of the Botanical Gardens of Brisbane, Australia. The two men were struck with the majestic beauty of the specimens found growing in the rain forests of Queensland. A distinction was made between Macadamia integrifolia (smooth shelled) and Macadamia tetraphylla (rough shelled) which also produces a nut that is edible, although not as good for roasting as Macadamia integrifolia. The genus Macadamia was named after a prominent scientist of that time, Dr John McAdam.
Macadamia trees grow slowly to heights of 12 to 15 metres. They have shiny dark green leaves, and bear sprays (racemes) of long, delicate, sweet-smelling white or pink blossoms. Each spray of 40 - 50 flowers produces from four to fifteen 'nutlets' which will eventually ripen into nuts.
The nuts themselves grow encased in a hard, woody shell, which is protected by a green-brown fibrous husk. In its natural state a macadamia tree will have flowers, nutlets and mature nuts growing simultaneously, in profusion for much of the year. The nuts fall to the ground between March and September each year and are harvested by pin wheel harvesters at regular intervals.
