|discussion=<p><i>Calamagrostis epigejos</i> is an introduced Eurasian species that was first found in North America in the 1920s. It grows in waste places, along roadsides, in juniper swamps, sandy woods, and thickets, and on rehabilitated tailings and cinders of railway beds. It is known from scattered locations in southern Canada and the contiguous United States. It is probably more widespread than shown. In 2005, it was collected from the west coast, in southwestern British Columbia, for the first time.</p><!--
--><p>In Ontario, <i>Calamagrostis epigejos</i> became established from impurities in seed mixtures used for highway roadcut revegetation. Rhizomes purchased from Manitoba have been used to stabilize gold mine tailings in Ontario. In Wisconsin, it was planted for erosion control at least as early as 1950. The Idaho record is from reseeded rangeland plots, and the Wyoming one from plants grown from purchased rhizomes.</p><!--
--><p>Greene (1980) stated that almost all plants from the Flora region fit <i>Calamagrostis epigejos</i> var. georgica (K. Koch) Griseb. Because there is notable variability and overlap in the characteristics used to distinguish the varieties in Eurasia, no attempt has been made to provide a varietal treatment for the Flora region. Hybrids of <i>C. epigejos</i> with <i>C. arundinacea</i> (L.) Roth are called <i>C. xacutiflora</i> (p. 721).</p>
