Acacia arrecta, commonly known as Yarnda Nyirra wattle or Fortescue wattle, [1] is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to arid areas in north western Australia.
The low dense spreading shrub typically grows to a height of 0.4 to 1 metre (1 to 3 ft) [2] and to a width of about 2 m (6 ft 7 in). It usually has multiple stems and can have few branches a ground level and has smooth, grey bark that can be fissured at the very base of the main stems. The branchlets have resinous ribbing. Like most species of Acacia it has phyllodes rather than true leaves. The grey-green, resinous and terete phyllodes narrow to a hard non-spiny point. The phyllodes are 15 to 40 mm (0.59 to 1.57 in) in length and have a diameter of around 1 mm (0.039 in) and have eight obscure nerves. [1] It blooms from January to December and produces yellow flowers. [2]
