See also 'Nomenclature' re the different species of barley, and that Hordeum distichum is the same as H. vulgare... Under H. distichum, it is noted that the six-row barley (which would be H. vulgare) is thought to be the barley of biblical times. Present in Egyptian heieroglyphs from 5000 BC and Sumerian cueiform tablets of 3,500 BC. Used as a currency in the code of Hammurabi in 1700 BC. Mentioned in the Bible, Exodus 9:31; Ezekiel 4:9 and Ruth 1:22. The classical Greeks had it as their major food source. In reign of Edward II (England) three grains of barley laid end to end made up the official inch (=2.5cm). WHile there were other methods of indicating the length of these measurements, 'the Israelites' ... [used] ... 'twenty-four barley corns' [presumably side by side] to measure a 'span' and forty-eight were 'a cubit'. A span is elswhere regarded as a hand span (thumb to little finger, outstretched) and a cubit was two spans or the distance from the tip of the middle finger to the point of the elbow.

Prescription only medicine: lignocaine
Hordeum vulgare Lignocaine. Hordeum vulgare, barley was the source of isogramine, synthesised by mistake when Erdtman, Hans von Euler's assistant in the 1930s was trying to make gramine as an nematocide. Erdman found that isogramine numbed his tongue and this led to the discovery of lignocaine, the local anaesthetic. In cardiovascular medicine lignocaine is given intravenously to treat arrhythmias.

Cultivated barley is homozygous for a mutation (sometimes two) that prevents the seeds from separating ('shattering') and other mutations which increase the number of rows of seeds. "In traditional classifications of barley, these morphological differences have led to different forms of barley being classified as different species. Under these classifications, two-rowed barley with shattering spikes (wild barley) is classified as Hordeum spontaneum K. Koch. Two-rowed barley with nonshattering spikes is classified as H. distichum L., six-row barley with nonshattering spikes as H. vulgare L. (or H. hexastichum L.), and six-row with shattering spikes as H. agriocrithon Åberg. Because these differences were driven by single-gene mutations, coupled with cytological and molecular evidence, most recent classifications treat these forms as a single species, H. vulgare L."
