Dodonaea microzyga, commonly known as brilliant hopbush, is a dioecious spreading shrub in the family Sapindaceae.

[3] Two varieties are recognised:[4] The species was first formally described by Victorian Government Botanist Ferdinand von Mueller in 1863 based on plant material collected in the vicinity of Neales River in South Australia during an expedition of John McDouall Stuart.

[3] New South Wales is the only State government jurisdiction in Australia with a conservation status applied to D. microzyga F.Muell.

[6] Feral goats specifically have been listed by the NSW Scientific Committee as a key threatening process to habitat degradation.

[7] New South Wales has the largest population of feral goats in Australia,[8] preferring the semi-arid rocky rangeland habitats shared with D. microzyga, being more secure from predators and human disturbance than the treeless plains.
