|discussion=<p>In Northwest Territories, <i>Ceratodon heterophyllus</i> is found only on Prince Patrick Island.</p><!--
--><p><i>Ceratodon heterophyllus</i> has also been treated as <i>C. purpureus</i> forma heterophyllus (Kindberg) Britton, and R. R. Ireland (1980) considered it to be a variety of <i>C. purpureus</i>, but J. S. Burley and N. M. Pritchard (1990) provided ample evidence that it is a distinct species. The broadly ovate leaves of <i>C. heterophyllus</i> grade into some alpine variations of <i>C. purpureus</i>.</p>
