It is generally accepted that Noogoora burr was first introduced to Australia at Noogoora Station in Queensland in the early sixties of last century, presumably as an impurity in imported cotton seed. Southern Europe and Central Asia are regarded as being the natural habitat of this plant, but it now occurs in many other widely-separated countries. In North America and South Africa, members of the genus Xanthium are referred to as cockle-burr or clot-burr.
