Scientific name: Dodonaea stenozyga
Conservation status in NSW: Critically Endangered
Commonwealth status: Not listed
Gazetted date: 11 Dec 2009
Profile last updated: 18 Oct 2022


Desert Hopbush is a rounded shrub to 2 metres high, with sticky leaflets and 4-angled branchlets. Leaves are 1 to 3.8 centimetres long including the stalk, and are composed of 2 to 6 linear leaflets, each 8 to 13.5 millimetres long and 0.5 to 2 millimetres wide. The unisexual flowers are hairless and inconspicuous. Fruit is a 4-winged capsule, 8.5 to 14.5 millimetres long and 10 to 17 millimetres wide, with the wings 3 to 6.5 millimetres wide and leathery.


Presumed extinct in NSW (with the only record from the Darling River prior to 1859) until recorded in 1998 from Nanya Station, north west of Wentworth in far south-western NSW. A recent record of two plants from a property to the west of Lake Victoria have yet to be confirmed. Widespread in southern Australia, from southern Western Australia, through South Australia to western Victoria.

Habitat and ecology

  • A shrub of semi-arid mallee scrub or open eucalypt woodland, usually on sandy soil.
  • At its NSW locality, a single shrub was recorded growing in Eucalyptus oleosa shrubland on a sandy swale, with Acacia colletioides, Eremophila glabra, E. scoparia, Maireana pentatropis, M. pyramidata, Olearia muelleri, O. pimeleoides, Grevillea huegelii and Senna spp.
  • Grows on a variety of soil types over its range and with a number of different dominant species. In eastern areas it occurs with Alectryon oleifolius, Senna sturtii, S. artemisioides, Scaevola spinescens, Olearia magniflora and mallee eucalypts.
  • Flowers in spring to early summer (September to December) and mature capsules are usually present at the same time.
  • Studies into the influence of fire and edaphic factors on the germination of Dodonaea viscosa revealed that seeds were killed by hot, slow-burning litter fires but germination was somewhat enhanced following cooler fire treatments. The fire response of Dodonaea stenozyga may be similar but has not been investigated.
  • Recorded in populations as occasional small shrubs, dense undershrubs, locally abundant and frequent. A single plant two metres high was recorded at the NSW site.
