Alectryon subdentatus is a tall shrub/small tree in the Sapindaceae family, and was first described in 1863 as Nephelium subdentatum by Ferdinand von Mueller,[2][3] and then in 1879 was assigned to the genus, Alectryon, by Ludwig Radlkofer.

[2][4] It is native to Queensland and to New South Wales in Australia, where it is found in the dry tropical biome.

[1] It grows as a shrub or small tree (to a height of 11 m).

Its bark is grey to brown which, smooth at first, becomes rough and scaly.

[5] The leaves are alternate and compound with four to six opposing leaflets, and the lowest pair is much smaller than the others.
