Sometimes considered native to Australia, but now largely beleieved to be widely naturalised in the northern and eastern parts fo the country (i.e. the northern parts of the Northern Territory, northern and eastern Queensland, and north-eastern New South Wales). Also naturalised on Norfolk Island.
Chinese burr (Triumfetta rhomboidea) is regarded as an environmental weed in Queensland.
