Recent field work revealed the probable naturalization of Conyza sumatrensis and C. bonariensis in Belgium, two species previously considered as ephemerous in Belgium. The present Belgian distribution pattern of both taxa is provided and compared with that of the adjacent territory in France. A key for the species of the genus Conyza in Belgium is proposed. The resumed hybridization and/or the presence of other taxa of the genus Conyza in the studied area is discussed.Conyza bonariensis et Conyza sumatrensis : en voie de naturalisation r{\'e}cente en Belgique 1 Des recherches r{\'e}centes r{\'e}v{\`e}lent la naturalisation probable de Conyza sumatrensis et de C. bonariensis en Belgique, deux taxons consid{\'e}r{\'e}s jusqu{\textquoteright}{\`a} pr{\'e}sent comme seulement adventices.
