Acacia jonesii is a species of Acacia native to eastern Australia.
The spreading slender shrub typically grows to 0.4 to 4 metres (1 to 13 ft) in height with an erect to spreading nature usually with a slender to straggly habit.[1] It has smooth brown to grey-green often mottled bark, terete and glabrous branchlets and subsessile leaves that are 1 to 6.5 centimetres (0.4 to 2.6 in) long.[2] The rachis are 1 to 7.5 cm (0.39 to 2.95 in) in length and hold 2 to 11 pairs of pinnae that are 0.4 to 4 cm (0.16 to 1.57 in) in length with 4 to 21 pairs of pinnules. The pinnules usually have an oblong or oblanceolate shape and will tend to incurve as they dry and are 2.5 to 6 mm (0.098 to 0.236 in) in length and 0.8 to 1.8 mm (0.031 to 0.071 in) wide.[1]
It has a limited distribution in coastal regions in central and southern New South Wales. It is restricted to the area between Bargo in the north out to Goulburn in the east and down to around Nowra in the south where it is still considered to be rare. It grows in clay soils often over or around sandstone as a part of dry sclerophyll woodland and forest communities.[1]
