Northern Hemisphere , temperateSouth America , and alsoSouth Africa .One species, "H. vulgare" (
barley ), is of major commercial importance as acereal grain, used as fodder crop and formalting inbeer andwhiskey production. Some species are nuisanceweed s introduced world-wide by human activities others endangered due to habitat loss."Hordeum" species are used as food plants by the
larva e of someLepidoptera species including The Flame,Rustic Shoulder-knot andSetaceous Hebrew Character .Species
