Taxonomic Review of Leymus (Poaceae)

Abstract:

Leymus Hochst. is a genus with important economic value in Triticeae (Poaceae). Most of Leymus species are forage grasses for animal husbandry. Some species used as important germplasm resources for grass breeding and improving breeds of crops due to the characteristics of enduring cold, drought, and alkali. Many unresolved taxonomic questions are present in Leymus, such as the generic limit/circumstance, the species delimitation, and the interspecific phylogenetic relationships. A taxonomic review of the genus was provided in order to accumulate background knowledge for further utilization of Leymus.
