Crinum flaccidum, known variously as the Darling lily, Murray lily or Macquarie lily, is a species of flowering plant in the family Amaryllidaceae. It is native to inland Australia. The Darling river people — the Paakantyi — called this plant paalampaltharu.
Crinum spp. are found in tropical and subtropical regions throughout the world including Africa, Australasia and India. Crinum spp. is found in all mainland states of Australia. C. flaccidum is found broadly scattered along floodways of inland river systems, primarily on the eastern half of Australia. These areas include eastern Northern Territory, Queensland, New South Wales, north-eastern Victoria and eastern South Australia. Additionally, disjunction populations can be found in the north-west corner of Western Australia.
