Derivation of the botanical name:
Macadamia, after John Macadam (1827 – 1865), a Scottish-Australian chemist, medical teacher, Australian politician and cabinet minister. Honorary Secretary of the Burke and Wills expedition. The genus Macadamia was named after him in 1857. He died in Australia aged 38.
integrifolia, from Latin integer, entire and folium, a leaf, referring to the leaf margins which do not have teeth.
  • The standard author abbreviation Maiden is used to indicate Joseph Maiden (1859–1925), a botanist who made a major contribution to knowledge of the Australian flora, especially the Eucalyptus genus.
  • The standard author abbreviation Betche is used to indicate Daniel Ludwig Ernst Betche (1851, in Potsdam – 1913, in Sydney), a German-Australian horticulturist and botanist.

Macadamias were introduced into Israel in the 1950s; some of the first trees were planted in the experimental plot on the grounds of the Weizmann Institute, Rehovot.
