Corymbia aparrerinja, commonly known as ghost gum,[2] is a species of tree that is endemic to Central Australia.

[2][3] Corymbia aparrerinja was first formally described in 1995 by Ken Hill and Lawrie Johnson from specimens collected on Gosses Bluff by Herbert Basedow in 1925.

[3][5] Ghost gum occurs in arid areas of Central Australia on rocky slopes, red sand flats and dry creek beds.

It is found from near Giles in Western Australia, through the south of the Northern Territory as far north as Tennant Creek to near Mount Isa and Barcaldine in Queensland.

[7] In 1891 in Barcaldine, a ghost gum known as the Tree of Knowledge was the focal point of a gathering of striking sheep shearers, a key event leading to the formation of the Australian Labor Party.
