Bromus danthoniae
Bromus danthoniae, the oat brome or three-awned brome, is a species of flowering plant in the family Poaceae, native to Turkey, Cyprus, the Caucasus region, the Middle East, Central Asia, Afghanistan, Pakistan, the western Himalayas, and Tibet. It is rarely discovered growing in other locations, but apparently not in sustained populations. It grows in a wide variety of habitats, and shows morphological variation due to the differing conditions in those habitats. References
