A member of the ‘A. wilhelmiana group’ and similar to A. barattensis in its long, narrow, flat but thickened phyllodes with two obscure nerves on each face. Acacia barattensis, however, has 4-merous flowers and obscurely 3-nerved phyllodes lacking a longitudinal medial groove. Thought to hybridise with A. paradoxa in S.A.
