|discussion=<p><i>Calamagrostis canadensis </i>var.<i> macouniana</i> is common in marshes and mud flats. It ranges eastward from Saskatchewan to Prince Edward Island and Nova Scotia, and from North Dakota and Missouri to New Jersey and Virginia. According to C.L. Hitchcock (Hitchcock et al. 1969), it may extend as far west as Idaho.</p><!--
--><p>Vernon Harms (pers. comm.) reports that in the southern grassland region of Saskatchewan, intermediates between <i>Calamagrostis canadensis </i>var.<i> macouniana</i> and <i></i>var.<i> canadensis</i> appear to be more common than plants that fit <i></i>var.<i> macouniana</i> well. Some specimens that seem nearest to <i></i>var.<i> macouniana</i> stretch across southern Saskatchewan south of 51° N latitude, from the Cypress Hills in the west to the Souris Valley in the east. Harms' observations suggest that it may not be practical to recognize this variety.</p>
