|discussion=<p><i>Calamagrostis cinnoides</i> is found on roadsides, in ditches, pond edges, and boggy streamhead seepages, and along streams in oak or oak-pine woods on sandy to peaty soils, at 5-1100 m. Its range extends throughout eastern North America, from Nova Scotia and Maine to Georgia and Louisiana. It is adventive in Ohio.</p><!--
--><p>Since <i>Arundo</i> canadensis Michx. was cited as a synonym for both <i>Arundo</i> cinnoides Muhl. and <i>Calamagrostis cinnoides</i>, both of these latter combinations are considered to be superfluous—and thus illegitimate—names, even though they differ taxonomically from <i>A. canadensis</i> Michx. A proposal is in preparation to conserve the name <i>C. cinnoides</i> over the less frequently used, but legitimate, combination C. coarctata Eaton.</p>
