This poorly known species is perhaps better regarded as a northern variant of A. microbotrya from which it is distinguished most reliably by its slightly broader pods. Its phyllodes are more obtuse than those normally found on A. microbotrya , however, obtuse phyllode forms of A. microbotrya do occur, especially in the region N of Moora.
