267 Bromus erectus Huds.

This polymorphic species (four subspecies distinguished in Fl. Eur. 5/1980, p. 185) obviously originates from C. and S. Europe. From there it has been spread to N. Europe, S. Africa, N. and S. America and New Zealand. The closely related B. fibrosus Hack. (syn.: B. riparius Rehm.), occurring mainly in SE. Europe, is also mapped. Cf. also Meusel et al. 1965, map p. 43.
