1. Dasypyrum villosum (L.) P. Candargy (syn.: Haynaldia villosa (L.) Schur, Agropyron villosum (L.) Link, Secale villosum L., Triticum villosum (L.) Bieb.) (Medit.) – A rare and ephemeral alien. Probably first collected near a grain mill in Leuven in 1887. Furthermore seen in Quaregnon in 1892 and on a grain dump in Andrimont in 1955. Exceptionally recorded as a wool alien in the Vesdre valley near Verviers between 1893 and 1947 (Lambinon 1959). From 1995 onwards regularly seen by roadsides and railway tracks or on wasteland in port areas (especially Gent and Antwerpen) (see Verloove & Vandenberghe 1997). Probably most recently seen on an unloading quay for cereals in the port of Gent in 2011 (see also: http://waarnemingen.be/waarneming/view/55282264). All recent records are associated with grain importation.
In general appearance Dasypyrum villosum is very reminiscent of Secale cereale and is possibly overlooked. It is distinctive by its glume keels with hairs that are arranged in tufts.
