(Crinum flaccidum)
Crinum flaccidum, known variously as the Darling lily, Murray lily or Macquarie lily, is a species of the family Amaryllidae native to inland Australia. The Darling river people — the Paakantyi — called this plant paalampaltharu. In the 1889 book The useful native plants of Australia, the botanist Joseph Henry Maiden wrote: "This exceedingly handsome white-flowered plant, which grows back from the Darling, has bulbs which yield a fair arrowroot. On one occasion, near the town of Wilcannia, a man earned a handsome sum by making this substance when flour was all but unobtainable. South Australia, Victoria, New South Wales, and Queensland."
