Description
Acacia aulacocarpa grows as a shrub with a height of {{cvt|0.5|to|2|m}} or as a small tree with a typical height of {{cvt|2|to|8|m}} but can reach heights of up to {{cvt|15|m}}. The bark is smooth, or cracked with shallow fissures on the largest trees. The phyllodes are dimidiate to more or less sickle-shaped, mostly {{cvt|50–125|mm}} long, {{cvt|7–35|mm}} wide, thinly leathery, glabrous and more or less glaucous. The flowers are bright golden-yellow and borne in one or two cylindrical spikes {{cvt|20–50|mm}} long on a peduncle {{cvt|4–8|mm}} long. Flowering occurs between January and June and the pods are narrowly oblong, sometimes twisted, {{cvt|15–80|mm}} long and usually {{cvt|8–15|mm}} wide, containing brown to black seeds {{cvt|3.5–5|mm}} long with a greyish-cream aril.{{cite web |last1=Maslin |first1=Bruce R. |last2=Kodela |first2=Phillip G. |editor-last1=Kodela |editor-first1=Phillip G. |title=Acacia aulacocarpa |url=https://profiles.ala.org.au/opus/foa/profile/Acacia%20aulacocarpa |publisher=Flora of Australia.

Taxonomy
The species was first formally described in 1842 by George Bentham, from an unpublished description by Allan Cunningham in the London Journal of Botany from specimens collected at Bowen.{{cite web |title=Acacia aulacocarpa |url=https://biodiversity.org.au/nsl/services/rest/instance/apni/463049 |publisher=Australian Plant Name Index |access-date=1 February 2025}}{{cite journal |last1=Bentham |first1=George |title=Notes on Mimoseae, with a synopsis of species. |journal=London Journal of Botany |date=1842 |volume=1 |pages=378–379 |url=https://www.biodiversitylibrary.org/item/40367#page/382/mode/1up |access-date=1 February 2025}} The specific epithet (aulocarpa) means 'furrow-fruit', referring to the markings on the pods.
Distribution
Acacia aulacocarpa has a discontinuous distribution, mainly in coastal areas and nearby tablelands from near Daintree to near Brisbane in Queensland, and near Grafton in New South Wales. It grows in clay or loam along watercourses, in sandy soil on rocky outcrops in forest and shrubland or in woodland on sandstone.
