Sporobolus anglicus (common cordgrass) is a hybrid-derived species of cordgrass that originated in southern England in about 1870 and is a neonative species in Britain. It was reclassified as Sporobolus anglicus after a taxonomic revision in 2014, but its previous name, Spartina anglica is still in common usage. It is an allotetraploid species derived from the hybrid Sporobolus × townsendii, which arose when the European native cordgrass Sporobolus maritimus (small cordgrass) hybridized with the introduced American Sporobolus alterniflorus (smooth cordgrass). Common cordgrass is a herbaceous
