AVH map***

Acacia beckleri is superficially similar to A. notabilis which has shorter and wider phyllodes and to A. gladiiformis. There are doubtful records from the Dubbo (CWS) and Cobar (NWP) areas which were probably cultivated or naturalised; there is a single uncertain record from Jerilderie (SWP). A. beckleri subsp. megaspherica O'Leary (from the Flinders Ranges, S.A.) has larger flower heads (74-140 flowers per head) and thicker peduncles (2-4 mm wide).
