Hordeum distichon, the common barley or two-rowed barley, is a cultigen of barley, family Poaceae. It is native to Iraq, and is widely grown throughout temperate regions of the world. ^[1] Some authorities consider it a subspecies of six-rowed barley, Hordeum vulgare . ^[2] It is the principal raw material for malting and brewing beer in Europe, as it is lower in protein than the six-rowed barley usually used in North America. ^[3]
