Acacia anfractuosa is a shrub or tree of the genus Acacia and the subgenus Plurinerves that is endemic to Western Australia.
The spindly to diffuse or weeping shrub or tree typically grows to a height of 1.3 to 4.5 metres (4 to 15 ft). [1] The pendulous, flexuose and glabrous branchlets have resinous new shoots. The green to grey-green, linear phyllodes are widely and strongly incurved. They are 5.5 to 23 cm (2.2 to 9.1 in) on length and 1 to 2 mm (0.039 to 0.079 in) wide with a wide yellowish central nerve and one to three finer parallel intervening nerves. [2] It blooms from July to December and produces yellow flowers. [1] The simple inflorescences occur singly or in pairs in the axils. The spherical to widely ellipsoid shaped flower-heads contain 22 to 32 densely packed golden flowers and are around 7 to 12 mm (0.28 to 0.47 in) in length with a diameter of 6 to 8 mm (0.24 to 0.31 in). The linear, curved, dark brown seed pods with yellow margins form after flowering. The pods are raised and constricted between seeds and have a length of around 12 cm (4.7 in) and a width of 1.5 to 2.5 mm (0.059 to 0.098 in). The glossy mottled brown linear-elliptic shaped seeds within the pods are 4.5 to 5 mm (0.18 to 0.20 in) in length. [2]
The species was first formally described by the botanist Bruce Maslin in 1976 as part of the work Studies in the genus Acacia (Mimosaceae) - Miscellaneous new phyllodinous species as published in the journal Nuytsia . It was reclassified as Racosperma anfractuosum by Leslie Pedley in 2003 and then transferred back to the genus Acacia in 2006. [3] It is quite closely related to Acacia sciophanes and also similar in appearance to Acacia heteroneura and Acacia merinthophora . [2]
