Upright or spreading shrub or small tree to 6 metres in height. The drooping ‘leaves’ (phyllodes) are long (to 16 centimetres), straight or slightly curved and usually somewhat rounded at the tip. Unlike A. implexa, which it often resembles, A. difformis has two long-itudinal veins, though the midvein is more prominent. The globular yellow flower heads are produced in clusters from the phyllode bases or (rarely) the ends of branches. The pods reach 20 cm in length but are usually around 0.5 cm in width. They may be straight or slightly curved and are said to resemble strings of beads (moniliform).
Seed is protected by a hard seed coat which must be broken (either by nicking, abrading, or soaking briefly in near-boiling water) before it will germinate. Germinates readily after treatment. May also grow from cuttings.
Generally December and January.
Uncommon but locally abundant, often forming dense stands. The largest populations occur in The Rock TSR and along Junee Reefs Rd. Smaller populations occur on The Gap Rd.
