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, 2013), Gent (1999), Roeselare (1994, 1996, 2003), etc… In 2015 also seen near a small grain mill in Moen. Usually recorded by railway tracks or on unloading quays, often with Cota austriaca, but much scarcer than the latter.
