Acacia barattensis, commonly known as Baratta wattle, is a shrub of the genus Acacia and the subgenus Plurinerves that is endemic to a small area in South Australia where the species is considered to be rare. [1]
The glabrous and viscid shrub that typically grows to a height of 2 to 3 m (6 ft 7 in to 9 ft 10 in). It has slender branchlets that are often coated in a black powdery substance. Like most species of Acacia it has phyllodes rather than true leaves. The slender and erect phyllodes have a narrowly linear shape and are usually shallowly incurved. The resinous and pungent phyllodes have a length of 5 to 10 cm (2.0 to 3.9 in) and a width of 1 to 1.5 mm (0.039 to 0.059 in) and have three obscure nerves per face. [2] It blooms between April and December producing simple and axillary inflorescences with spherical pale yellow coloured flower-heads. Following flowering dark brown seed pods form that are flat and straight with thick straw coloured margins. The pods are around 15 cm (5.9 in) in length and 3.5 mm (0.14 in) wide and contain hard brown to black coloured seeds with an ovoid shape that are about 6 mm (0.24 in) in length and 2 mm (0.079 in) wide. [1]
The shrub was first formally described by the botanist John McConnell Black in 1932 as part of the work Additions to the Flora of South Australia. No. 30 as published in the Transactions and proceedings of the Royal Society of South Australia. It was reclassified as Racosperma barattense by Leslie Pedley in 2003 then returned to genus Acacia in 2006. [3] It belongs to the Acacia wilhelmiana group. The specific epithet is taken from the name Baratta Station, the pastoral lease where the type specimen was collected from. [2]
It has a limited distribution in the Flinders Range of South Australia and is considered to be a rare species which was previously thought to be extinct. It is commonly situated among outcropping areas of quartzite along the lines of watercourses and on the slopes of rocky gulleys growing in skeletal soils in open woodland or shrubland communities often in association with Eucalyptus camaldulensis , Eucalyptus flindersii and Callitris glaucophylla .
