Range DescriptionThe species is a predominantly a temperate Old World species, but occurs from Macaronesia and North Africa north to Scandinavia, east through Siberia, the Caucasus, Turkey, Iraq, Iran, Palestine, Afghanistan, Pakistan, (Dandy 1971, Ghafoor accessed through www.efloras.org), the western Himalayas (The Board of Trustees of the Royal Botanic Gardens, Kew 2010) to China (Wang Quingfeng in prep.). It is naturalised in New Zealand (Allan Herbarium 2000), the west coast of North America (Oregon, California) and Chile (Haynes and Barre-Hellquist 2000).
It is widespread in north and central Europe, but most abundant in the Mediterranean basin. It has an interesting relationship with A. plantago-aquatica with which its range overlaps throughout much of Europe, but the latter species is increasingly relatively abundant in the north, whilst A. lanceolatum more or less replaces A. plantago-aquatica in the south.
