About

Acacia coriacea, commonly known as wirewood, wiry wattle or desert oak, is a species of flowering plant in the family Fabaceae and is endemic to northern Western Australia. It is a spreading shrub or tree with thin bark, linear to very narrowly elliptic phyllodes, spherical heads of pale lemon yellow or cream-coloured flowers and twisted, curved or coiled pods resembling a string of beads. Indigenous Australians know the plant as Gunandru.

Where it grows

Wirewood is widely distributed in the north of Western Australia where it grows in sand or limestone on coastal dues and ridges, sandplains and along watercourses in the Avon Wheatbelt, Carnarvon, Gascoyne, Gibson Desert, Great Sandy Desert, Pilbara, Swan Coastal Plain, Tanami and Yalgoo bioregions. Subspecies coriacea has a near coastal distribution in the Avon Wheatbelt, Carnarvon, Gascoyne, Pilbara, Yalgoo bioregions and subsp. pendens in the Carnarvon, Gascoyne, Pilbara and Swan Coastal Plain bioregions.

Uses

Indigenous Australians used the seeds of this species as a food source, the wood for making spears and shields, and the ash produced from the wood was used with native tobacco (Nicotinia species) as a chewing quid.
