Description
editThe low spreading multi-stemmed shrub typically grows to a height of 0.05 to 0.35 metres (0.2 to 1.1 ft)[1] with a Prostrate to semi-prostrate habit with a lignotuber and hairy branchlets that have oblong to widely ovate stipules. The leaves are composed of two or three pairs of pinnae where the proximal pinnae have a length of 3 to 7 mm (0.12 to 0.28 in) and the distal pinnae have a length of 7 to 20 mm (0.28 to 0.79 in). The proximal pinne and composed of two to three pairs of pinnules while the distal pinnae are composed of three to seven pairs of pinnules that are 4 to 6 mm (0.16 to 0.24 in) in length and about 1 mm (0.039 in) wide.[2] It blooms from November to January and produces yellow flowers.[1]
Etymology
editA. preissiana was first described as Acacia obscura var. preissiana by Carl Meissner in 1842,[3][4] but in 1975 Bruce Maslin elevated it to species rank, naming it Acacia preissiana.[3][5]
Distribution
editIt is native to an area in the South West, Peel and Great Southern regions of Western Australia where it is commonly found growing in lateritic based soils.[1] The range of the plant extends from north of Binddon in the north down to the Whicher Range in the south. A single collection of the species has been made from around Albany where it is usually a part of Eucalyptus marginata or Eucalyptus wandoo forest communities.[2]
