The name is from the Greek leios (smooth) and calyx (a husk, or the cup or calyx of a flower), referring to the usually glabrous calyx (N. Hall & L.A.S. Johnson, The Names of Acacias of New South Wales, 1993). Related to Acacia concurrens and similar to A. crassa. Intermediates between A. concurrens and A. leiocalyx occur in northern New South Wales.
