Trachyspermum ammi (L.) Sprague ex Turrill (syn.: T. copticum (L.) Link) (As.) – A very rare and ephemeral alien. Formerly recorded as a wool alien in Ensival and Nessonvaux in the valley of river Vesdre (1892-1896; see Fabri & Lambinon 1991). Also seen on the bank of river Zenne south of Brussel in 1985, apparently as a food refuse alien.
