Salvia viridis L. (syn.: S. horminum L.) (Medit., SW-As.) – A very rare and ephemeral alien. Formerly recorded at the railway station of Statte near Huy (1916), with several other southern European grain aliens. Since 2009 more regularly seen, for instance in Antwerpen, Burg-Reuland and Ghlin. Recent records are probably mostly escapes from flower seed mixtures.
