|discussion=<p>Variety densifolium is absent from the Arctic, but widespread across northern North America. Most of the eastern North American plants that have been called Polytrichastrum formosum probably belong to this variety, although many of the older herbarium specimens so named are P. ohioense. Variety densifolium is evidently monoicous (see T. Osada 1966), although admittedly this is difficult to demonstrate.</p>
