The ancestor of two-rowed barley. It is considered poor fodder and can become a serious weed of cereal crops. It is not always easy to distinguish it from two-rowed barley, particularly when the latter is self sown in ruderal sites.

Annual; culms up to 70 cm high, erect or geniculately ascending. Leaf-blades 5-16 cm long, 4-8 mm wide, glabrous or scabrid and sometimes sparsely hairy. Spike laterally compressed, 4-9 cm long (excluding the awns); rhachis densely hairy on the margins, fragile. Central spikelet sessile; glumes narrowly linear-lanceolate, long-awned, 13-23 mm long including the awn, densely silky hairy; lemma ovate-lanceolate 12-14 mm long, glabrous; awn 4-14 cm long, stout, very scabrid; anthers 23-3 mm long. Lateral spikelets male or vestigial, sessile; glumes like those of the central spikelet; lemma rounded-obtuse at the tip, 7-9 mm long.

Wilde gerst

fornì da wikipedia NL
Wilde gerst (Hordeum spontaneum, synoniem: Hordeum vulgare subsp. spontaneum) is een voorouder van gerst en behoort tot de familie Poaceae. Wilde gerst komt van nature voor in Noord-Afrika, het Midden-Oosten, India en zuidwest China. Domesticatie heeft plaatsgevonden op twee tijdstippen. De eerste domesticatie vond 10.000 jaar geleden plaats in de Vruchtbare Sikkel en later nog een keer in een gebied verscheidene duizenden kilometers meer naar het oosten. De gerst geteeld in Europa en Amerika stamt af van de eerste domesticatie en die in Centraal Azië en in delen van het Verre Oosten van de tweede.[1]
Wilde gerst is een eenjarige plant, die sterk op gerst lijkt, maar iets smallere bladeren, langere stengels, langere naalden, langere en slankere aar met een broze aarspil en kleinere graankorrels heeft.[2] De aar is tweerijig. De kafjes zijn net als bij gerst vergroeid met de graankorrel.
