Name is from the Latin asper, meaning rough, uneven, harsh, rugged; referring to the roughness of the branches and phyllodes caused by the prescence of short, erect, stiff hairs (N. Hall & L.A.S. Johnson, The Names of Acacias of New South Wales, 1993). Specimens in New South Wales are referable to subsp. aspera. Allan Cunningham referred the narrow phyllode forms, occurring in the Harvey Ranges near Peak Hill, to A. erythrocephala.
