Similar to A. frigescens in having broad, 3-veined phyllodes with the tips often callose, heads in short racemes, similar perianth and bracteoles and seeds with a fleshy funicle. The 2 species differ in the shape of the phyllodes and the twisted and coiled legumes of A. implexa. See also notes under A. melanoxylon.
