2. Cota austriaca (Jacq.) Schultz-Bip. (syn.: Anthemis austriaca Jacq.) (E-, C- and SE-Eur.) – A rather rare and probably always ephemeral alien, sometimes more or less persisting for some years. Formerly recorded as a wool alien in the Vesdre valley, at least between 1887 and 1901. Furhermore seen as a grain alien in Wilsele in 1894. From 1997 onwards frequently seen on unloading quays, along railway tracks,… in port areas, always associated with cereals (Verloove & Vandenberghe 1998), for instance in Antwerpen, Gent, Izegem and Roeselare. In some years, for instance 2011, exceedingly common and recorded nearly where-ever large amounts of cereals are transported.
Possibly under-recorded (see also Oesau 1978) and confused with native Anthemis arvensis.
