In the Anti-tank Ditch ({\textquoteright}Antitankgracht{\textquoteright})  north-east of Antwerp a large population of Myriophyllum heterophyllum Michaux was discovered. Further research indicated this species is present at other locations in the province of Antwerp. Vegetative differences with native species of Myriophyllum are discussed.Myriophyllum heterophyllum, une nouvelle  plante aquatique invasive.
