Asia, Siberia; introduced in many temperate countries. Most Turkish specimens have rather narrow spikes (c. 10 mm broad). Some, marked with an asterisk in the above citations, have spikelets which are only slightly divergent from the rachis; they resemble A. desertorum (Fischer ex Link) Schultes, but their spikes are narrowly elliptic, not linear as in the latter. Bornm. 1892:3126 is characterised also by having shortly awned lemmas (awns c. 1 mm).
