First record of Iris pseudacorus L. (Iridaceae) in natural and artificial wetlands of western dryland, Argentina

Abstract

Iris pseudacorus is an invasive macrophyte in wetland ecosystems around the world. In Argentina, its distribution range covers the eastern and central regions, registering its presence in protected, natural and artificial wetlands. We report its presence in desert natural wetlands and artificial irrigation systems (Mendoza River and Tunuyán River basins, Mendoza). We provide a description of the specimens and photographic material, adding new georeferenced records and the first specimens to scientific reference collections of drylands in western Argentina.
