	abstract = {Hydrocotyle ranunculoides L. f., an invasive neophyte in the surroundings of Ghent (East-Flanders, Belgium). Hydrocotyle ranunculoides {\textemdash} a North American troublesome aquatic weed species {\textemdash} is rapidly spreading in ditches and small streams in the vicinity of Ghent. Obviously, the species has been introduced intentionally for horticultural purposes and for experimental waterpurification and escaped with rapidity ever since. Its actual distribution pattern is drawn, an identification key for the genus Hydrocotyle in Belgium is proposed and further ecologie and taxonomie notes are provided.},
