The common name for this genus is "[[wild rye]]"; however, members of the genus ''[[Elymus (genus)|Elymus]]'' are also sometimes given the same common name. The two are closely related and sometimes combined into one genus. The two names are [[anagrams]] of each other. GA3 and KNO3 have been shown to increase the effects of germination in a species of this genus known as ''leymus chinensis.''<ref>{{cite journal|last1=Wen Hu|first1=Xiao|title=Seed Dormancy, Seedling Establishment and Dynamics of the Soil Seed Bank of Stipa bungeana (Poaceae) on the Loess Plateau of Northwestern China|journal=PLoS|date=Nov 14, 2014|volume=9|issue=11|doi=10.1371/journal.pone.0112579|pmid=4232413|url=http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4232413/|accessdate=7 October 2015}}</ref><ref>{{cite journal |url=http://www.amjbot.org/cgi/content/full/88/4/553 |title=Genomic and genetic relationships among species of ''Leymus'' (Poaceae: Triticeae) inferred from 18S–26S ribosomal genes |journal=American Journal of Botany |volume=88 |pages=553–559 |year=2001 |last1=Anamthawat-Jónsson |first1=Kesara |last2=Bödvarsdóttir |first2=Sigrídur K. |doi= 10.2307/2657053|issue=4}}</ref><ref>{{cite web |title=PLANTS profile for ''Leymus'' (wildrye) |work=[http://plants.usda.gov PLANTS Database] |url=http://plants.usda.gov/java/profile?symbol=LEYMU |publisher=United States Dept. of Agriculture |accessdate=2011-04-09}}</ref>
