About Acacia triptera Benth.
Acacia triptera Benth. typically grows to around 2 metres (6 feet 7 inches) tall, with an erect to spreading growth habit and terete, glabrous branchlets. Like most Acacia species, it has phyllodes instead of true leaves. The evergreen phyllodes are decurrent, shaped either falcate or sigmoidal, with a length between 1.5 and 5.5 centimetres (0.59 to 2.17 inches) and a width between 2 and 10 millimetres (0.079 to 0.394 inches). The phyllodes have many very closely spaced longitudinal veins.
Bright yellow flowerheads emerge from August to November. These simple inflorescences occur in pairs in the leaf axils, forming cylindrical flower-heads 1.5 to 3 centimetres (0.59 to 1.18 inches) long, densely packed with golden flowers. After flowering, the plant produces curled or twisted brown seed pods that measure 3 to 8 centimetres (1.2 to 3.1 inches) in length and 2 to 4 millimetres (0.079 to 0.157 inches) in width.
This species is distributed across Victoria, New South Wales, and Queensland, where it grows on sandhills or rocky outcrops in mallee, woodland, or heath habitats. In cultivation, established Acacia triptera plants tolerate dry periods and moderate frost.
