Macadamia integrifolia is a small to medium-sized tree, growing to 15 metres in height. Native to rainforests in south east Queensland and northern New South Wales, Australia. Common names include macadamia, smooth-shelled macadamia, bush nut, Queensland nut and nut oak.[2]

Macadamia integrifolia leaves are simple, oblong in shape, glossy, entire with wavy leaf margins and are 20 cm long and 10 cm wide.[3] The flowers are white or pink followed by woody, edible rounded fruits[4] which are 2 to 3.5 cm in diameter.

This tree is rarely cultivated for ornamental purposes.[2]

It has been introduced to Mexico and has done well in the states of Michoacán and Jalisco.[5]
