Leymus multicaulis
Also called Many Stem Wild Rye
Leymus multicaulis, also known as manystem wild rye or manystem lyme grass, is a species of the genus Leymus. The species name of manystem wild rye, multicaulis, suggests the “many stems” of the species. Leymus multicaulis is considered a type of grass. Manystem wild rye has only one cotyledon in each of its seeds. The xylem and phloem within the roots are arranged in a ring pattern. The vascular bundles are scattered throughout the stem. These traits make Leymus multicaulis a monocot. Leymus multicaulis is a flowering plant, or angiosperm.
Leymus multicaulis originates in Eurasia, its distribution extending from the Volga River Delta to Xinjiang, China. Only recently has Leymus multicaulis been introduced to the United States, particularly in the western regions, mainly Wyoming and Montana. Manystem wild rye is adapted to alkaline meadows and saline soils. It is also found growing as a weed throughout fields, roadsides and around human habitats. Leymus multicaulis is adapted to wet saline meadows, where there is heavy rainfall. From mountainous areas to bottomlands, Leymus multicaulis is able to grow productively. Unlike the other species of genus Leymus, L. multicaulis can tolerate harsh winter conditions.
