The remarkable gatherings of (sub-)tropical soya bean weeds in the vicinity of the Cargill-mill at Antwerp and the extreme richness of southern European cornfield weeds at G.G.T. at Ghent and near the paste-mill of Anco at Turnhout are noteworthy. Agrostis scabra - in the past misidentified as A. hyemalis in Belgium - has been found as an ephemerophyte at Ghent; the species is however also an established and expanding neophyte N of Antwerp.
Its local actual distribution is indicated.},
