Acacia triquetra, also known as the gold dust wattle,[1] is a shrub belonging to the genus Acacia and the subgenus Phyllodineae native to southern Australia.
The shrub typically grows to a height of 1.5 metres (4.9 ft) and has a glabrous and spreading habit. It has acutely angled branchlets that are ribbed below phyllodes. Like many species of Acacia it has phyllodes rather than true leaves. These appear on stem-projections and are patent to erect but usually inclined to ascending. The dark green phyllodes have a narrowly oblong to oblanceolate shape and can be straight or slightly curved. They have a length of around 10 to 25 mm (0.39 to 0.98 in) and a width of 2 to 6 mm (0.079 to 0.236 in) with an obscure midrib and lateral nerves.[2] It blooms between July and October usually mostly in September[3] and produces rudimentary inflorescences with spherical flower-heads that contain 10 to 18 golden flowers. After flowering firmly chartaceous seed pods form with a linear shape that are straight to shallowly curved. The pods have a length of up to 6 cm (2.4 in) and a width of 3 to 4 mm (0.12 to 0.16 in) with the seeds arranged longitudinally inside. The dark brown seeds are normally found to have an oblong shape with a length of 2.5 to 3.5 mm (0.098 to 0.138 in) and are ridged around the periphery.[2]
