Hordeum distichon s.l.
The common cultivated barley, occurring frequently but rarely persisting in waste places, fields, waysides and around farm buildings. It is mainly a relic of cultivation, but also occurs on roadsides from spilt grain and as a casual from wool shoddy and bird-seed. Lowland.
Barley has been cultivated in Britain for thousands of years, but was not recorded from the wild until 1908. This map includes records of the commonly cultivated H. distichon sens. str. and the rarer H. vulgare, which is also mapped separately. The species have sometimes been ignored by recorders, and are certainly under-recorded in some areas.
Unknown as a wild plant; widely cultivated in temperate regions throughout the world.
