Acacia jonesii

Acacia jonesii is an erect or spreading, often slender or straggling shrub that typically grows to 0.4–4 m (1 ft 4 in – 13 ft 1 in) high, and often reproduces by suckering. It has smooth brown to grey-green often mottled bark, and glabrous, terete branchlets. The leaves are bipinnate, subsessile, with 2–11 pairs of pinnae 5–40 mm (0.20–1.57 in) long and decreasing in size towards the leaf base, each pinna with 4 to 21 pairs of narrowly lance-shaped or narrowly oblong pinnules. The rachis, is 10–55 mm (0.39–2.17 in) long, there are minute glands at the base of all or most pairs of pinnae, and the midvein is closer to the edge of the pinnules. The flowers are mostly borne in racemes of spherical heads in axils on an often zig-zag peduncle 1–6 mm (0.039–0.236 in) long. Each head is 5–8 mm (0.20–0.31 in) in diameter, with 8 to 15 yellow to bright yellow flowers. Flowering occurs from July to October, and the pods are straight to slightly curved, 20–70 mm (0.79–2.76 in) long and 5.5–8 mm (0.22–0.31 in) wide and black or dark brown, straight sided or slightly constricted between some seeds.

This species of wattle has a limited distribution on the central and southern coast and tablelands of New South Wales between Bargo, Nowra and Goulburn where it grows in forest and woodland on sandstone and in clay soils.
