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.

A. 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]

[1] The range of the plant extends from north of Binddon in the north down to the Whicher Range in the south.
