Salvia reflexa
Salvia reflexa Hornem. (N-Am.) – A rather rare and ephemeral alien. Probably first recorded in 1947 in the valley of river Vesdre (as a wool alien) (Lawalrée 1949). Soon afterwards observed in several, widely scattered localities, for instance in Antwerpen (1949, 1954), Charleroi (1952-53), Jemappes (1958), Mechelen (1952), Mons (1951), Namur (1955), Surdents (1958) and Temse (1952) (see also Lawalrée 1953). Many records were from dumps (see also Lebeau 1954) and probably associated with cereals (including bird seed). According to Hanson & Mason (1985) Salvia reflexa is a common impurity in American millet seed. In the past decades still regularly seen, mostly in port areas (especially Antwerpen and Gent). All recent records are obviously related with grain importation (e.g. Lambinon 1991, Verloove & Vandenberghe 1995).
