Inflorescence arrangement

Acacia flowers are aggregated into heads or spikes which are usually borne on peduncles (peduncles rarely absent); the peduncles may arise directly from within the axil of the phyllodes or leaves (Simple) or may be arranged along a long or short, unbranched (Racemose) or branched (Paniculate) common axis.

This Feature is most easily determined when plants are in flower; in fruiting material care should be taken to ensure that the observed structures are correctly interpreted.

Paniculate. A branched raceme, i.e. a "raceme of racemes".

Panicles are not especially common in Acacia.
