It is commonly known as blue heronsbill in Western Australia,[1] and blue storksbill in South Australia.[2] In the United States, where the species is cultivated as a garden plant, it is commonly known as Australian stork's bill[3] and Australian filaree.[4] In the British Isles, it is commonly known as western stork's-bill.[5] DescriptionIt grows as an annual or perennial herb up to 60 centimetres high, with blue, purple or pink flowers.[1] TaxonomyThis species was published in 1845, based on a specimen collected from the vicinity of Perth, Western Australia by Ludwig Preiss in 1839. In 1958, Roger Charles Carolin published a subspecies, Erodium cygnorum subsp. glandulosum, but this has since been promoted to species rank as E. carolinianum.[6] No infraspecific taxa of E. cygnorum are currently recognised. Distribution and habitatIt is native to Australia, occurring in Western Australia, South Australia and the Northern Territory.[7] The National Herbarium of New South Wales lists E. cygnorum as also occurring in New South Wales,[8] but they further identify their specimens as E. cygnorum subsp. glandulosum;[9] that is, E. carolinianum. It favours red sand or clay loam, occurring in low-lying flats, along creeklines and on the margins of salt lakes.[1] References1. ^1 2 {{FloraBase | name = Erodium cygnorum Nees | id = 4335}} {{Taxonbar|from=Q5395277}}{{Geraniaceae-stub}}2. ^{{GRIN | name = Erodium cygnorum | id = 318212}}, citing {{cite book | author = Jessop, J.
