|discussion=<p>Cyrtomnium hymenophyllum often grows in pure stands in circumarctic and subarctic regions, in far northern North America, central west and central east Greenland, Europe, and Asia. It is readily recognized in the field by flat, bluish green leaves that are appressed against the dark brown stems. Plants growing in less optimal dry tundra are shorter and usually not matted together. The leaves are strongly heterophyllous, reflecting periods of fast and slow growth. Female plants are common throughout the range, and male plants occur more widely than those of C. hymenophylloides. Sporophytes are rare and have only been found in the Yukon (D. H. Vitt and D. G. Horton 1979), Northwest Territories, and British Columbia.</p>
