1. Cota altissima (L.) J. Gay (syn.: Anthemis altissima L.) (S-Eur., Caucasus, C-As.) – A rather rare and always ephemeral alien. First recorded in 1869 in a road verge in Nessonvaux and in 1895 in Wilsele (grain alien). A scarce wool alien in the valley of river Vesdre between 1901 and 1908. In the past decades more often observed, always as a grain alien (incl. birdseed) in port areas, for instance in Antwerpen (1998), Gent (1999), Roeselare (1994, 1996, 2003), etc… Usually recorded by railway tracks or on unloading quyas, often with Cota austriaca, but much scarcer than the latter.
