It was described as a new species in 1996. It became known to science when some grasses were collected in Turkey in 1979 and one type was successfully bred out, proving to be a natural hybrid. ''E. hoffmannii'' is derived from this hybrid between ''Elymus repens'' and the bluebunch wheatgrasses (''Pseudoroegneria'' spp.) of Turkey,〔Jensen, K. B. and K. H. Asay. (1996). (Cytology and morphology of ''Elymus hoffmanni'' (Poaceae: Triticeae): A new species from the Erzurum Province of Turkey. ) ''International Journal of Plant Sciences'' 157(6) 750-58.〕 such as ''Pseudoroegneria spicata''.〔(''Elymus hoffmannii''. ) USDA NRCS Plant Guide.〕 This is a rhizomatous perennial grass with stems up to 1.35 m tall. The spikes are up to half a metre long with spikelets up to 2.7 cm in length. This species can be distinguished from its relative, ''E. repens'', by its smaller rhizomes, longer leaves, and shorter awns.〔 This grass is used for grazing livestock. There are several cultivars available, including 'NewHy', which combines "the vigor, productivity, salt tolerance and persistence of quackgrass with the drought resistance, growth habit, seed quality and forage quality of bluebunch wheatgrass."〔Gordon, K. (Forage Focus NewHy offers more than salt tolerance. ) ''Beef Magazine'' December 1, 1999.〕 It remains edible for livestock later in the season than other wheatgrasses, and it withstands grazing pressure.〔('Newhy' Hybrid Wheatgrass Long Range Field Planting Plan. ) USDA NRCS.〕 It can produce two or more hay harvests.〔 Another cultivar is 'AC Saltlander', which is especially tolerant of higher soil salinity.〔 ==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「Elymus hoffmannii」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
