Diplarrena moraea, commonly known as white iris (or butterfly flag in the UK),[1] is a member of the iris family, Iridaceae. It occurs in Australian heathland and forest in New South Wales, Victoria and Tasmania.[2]
The species was formally described in 1800 by French naturalist Jacques Labillardière in Relation du Voyage à la Recherche de la Pérouse .
Diplarrena moraea is included in the Tasmanian Fire Service's list of low flammability plants, indicating that it is suitable for growing within a building protection zone.[3]
