The name refers to the strap-shaped phyllodes. The Aborigines made a flour from the seeds and used the gum as a food source. The roots are a host for the witchety grub (Xylentes leucomochla). Related to Acacia salicina, the pods of which do not break readily between the seeds. (T. Tame, Acacias of Southeast Australia, 1992).
