Previously, more species with [[disjunct distribution]]s were named as members of this genus ''Macadamia''.<ref name=Mastetal2008/> Genetics and [[Morphology (biology)|morphological]] studies published in 2008 show they have separated from the genus ''Macadamia'', correlating less closely than thought from earlier morphological studies.<ref name=Mastetal2008/> The species previously named in the genus ''Macadamia'' may still be referred to overall by the descriptive, non-scientific name of macadamia.

=== Etymology ===
The German-Australian [[botany|botanist]] [[Ferdinand von Mueller]] gave the genus the name ''Macadamia'' in 1857 in honour of the Scottish-Australian [[chemist]], medical teacher, and [[politician]] [[John Macadam]], who was the honorary Secretary of the [[Philosophical Institute of Victoria]] beginning in 1857.<ref>The proceedings of Philosophical Institute of Victoria, now the [[Royal Society of Victoria]] Rev: Mueller F (1857) Account of some new Australian plants.
