Formerly included species
Botanists now regard many species as better suited to other genera:[4] Arrhenatherum, Crithopsis, Dasypyrum, Elymus, Eremopyrum, Hordelymus, Leymus, Psathyrostachys, and Taeniatherum.
Etymology
The name Hordeum comes from the Latin word for "to bristle" (horreō, horrēre),[8] and is akin to the word "horror".
Distribution
Ecology
Hordeum species are used as food plants by the larvae of some Lepidoptera species, including the flame, rustic shoulder-knot and setaceous Hebrew character.
Some species have become weeds introduced worldwide by human activities, others have become endangered due to habitat loss.
