Only two species seem incontrovertible: A. arenaria and A. breviligulata.
• A. arenaria - European Marram Grass or European Beachgrass. Native to coasts of Europe (north to Iceland) and northwest Africa. Inflorescence to 25 cm long; broad.
• A. baltica has now been identified as a natural hybrid, × Ammocalamagrostis baltica, between Ammophila arenaria and Calamagrostis epigeios. The hybrid occurs in parts of northern Europe, mainly from the Baltic Sea west to eastern England.
• A. breviligulata - American Marram Grass or American Beachgrass. Native to coasts of eastern North America, including the shores of the Great Lakes. Inflorescence to 30 cm long; narrower than A. arenaria.
