Universidad Nacional Autónoma de México, México, D.F..〕 One species, ''H. vulgare'' (barley), is of major commercial importance as a cereal grain, used as fodder crop and for malting in beer and whiskey production. Some species are nuisance weeds introduced worldwide by human activities others endangered due to habitat loss. ''Hordeum'' species are used as food plants by the larvae of some Lepidoptera species, including the flame, rustic shoulder-knot and setaceous Hebrew character. The name comes from the Latin for bristle, and is akin to horror. ;Species〔〔(Biota of North America Program 2013 county distribution maps )〕〔(The Plant List search for ''Hordeum'' )〕〔(Atlas of Living Australia )〕 # ''Hordeum aegiceras'' - Mongolia, China including Tibet # ''Hordeum arizonicum'' USA (CA AZ NV NM), Mexico (Baja California, Sonora, Durango) # ''Hordeum bogdanii'' - from Turkey and European Russia to Mongolia # ''Hordeum brachyantherum'' - Russia (Kuril, Kamchatka), Alaska, Canada including Yukon, USA (mostly in the West but also scattered locales in the East), Baja California # ''Hordeum brachyatherum'' - Chile # ''Hordeum brevisubulatum'' - European Russia; temperate and subarctic Asia from Turkey and the Urals to China and Magadan # ''Hordeum bulbosum'' - Mediterranean, Central Asia # ''Hordeum californicum'' - USA (CA OR NV) # ''Hordeum capense'' - South Africa, Lesotho # ''Hordeum chilense'' - Argentina, Chile including Juan Fernández Is # ''Hordeum comosum'' - Argentina, Chile # ''Hordeum cordobense'' - northern Argentina # ''Hordeum depressum'' - USA (CA OR WA ID NV), British Columbia, Baja California # ''Hordeum distichon'' - Iraq # ''Hordeum erectifolium'' - northern Argentina # ''Hordeum euclaston'' - Brazil, Uruguay, Argentina # ''Hordeum flexuosum'' - Uruguay, Argentina # ''Hordeum fuegianum'' - Tierra del Fuego # ''Hordeum guatemalense'' - Guatemala # ''Hordeum halophilum'' - Argentina, Chile, Bolivia, Peru # ''Hordeum jubatum'' (foxtail barley) - widespread in USA and Canada; Asiatic Russia, Inner Mongolia, Central Asia, Caucasus # ''Hordeum × lagunculciforme'' - Iraq, Turkmenistan, Himalayas, western China # ''Hordeum lechleri'' - Argentina, Chile # ''Hordeum marinum'' (sea barley) - Europe, North Africa, southwestern and central Asia # ''Hordeum murinum'' (wall barley) - Canary Islands, Europe, North Africa, southwestern and central Asia # ''Hordeum muticum'' - Argentina, Chile, Bolivia, Peru # ''Hordeum parodii'' - Argentina # ''Hordeum patagonicum'' - Argentina, Chile # ''Hordeum × pavisii'' - France # ''Hordeum procerum'' - Argentina # ''Hordeum pubiflorum'' - Argentina, Chile # ''Hordeum pusillum'' (little barley) - widespread in Canada and USA; northern Mexico, Bermuda, Argentina # ''Hordeum roshevitzii'' - China, Korea, Primorye, Mongolia, Siberia, Kazakhstan # ''Hordeum secalinum'' - Europe, Mediterranean, Caucasus # ''Hordeum spontaneum'' - from Greece and Egypt to central China # ''Hordeum stenostachys'' - Brazil, Argentina, Uruguay, South Africa # ''Hordeum tetraploidum'' - Argentina, Chile # ''Hordeum vulgare'' (barley) - native to Middle East, now cultivated in many countries ;formerly included〔 Many species now regarded as better suited to other genera: ''Arrhenatherum, Crithopsis, Dasypyrum, Elymus, Eremopyrum, Hordelymus, Leymus, Psathyrostachys,'' and ''Taeniatherum'' ==References== * * * * * * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hordeum」の詳細全文を読む スポンサード リンク
