	abstract = {Petasites japonicus is naturalizing in the south of the province of Hainaut (Belgium). Petasites japonicus subsp. giganteus was discovered in a small waste ground (probably an old garden) along a former railway line at Sivry-Rance (Walloon province of Hainaut, Belgium). Only male plants were found. An identification key to the four species of the genus Petasites occurring in Belgium, phenological observations, a description of the habitat of this neophyte, and an overview of records in Belgium are provided. The mode of introduction and its status in Wallonia are discussed.},
