Diphasiastrum alpinum, the alpine clubmoss, is a species of clubmoss.[2] It was first described by Carl Linnaeus in his Flora Lapponica, 1737, from specimens obtained in Finland.
It has a circumpolar distribution across much of the northern parts of the Northern Hemisphere: much of Canada, the northwestern United States, northern and central Europe, Russia, China and Japan. It is an indicator of alpine tundra and boreal climates.[3] It is found in mountains and moors often with Calluna and grasses.[1][4][5]
Diphasiastrum alpinum grows 10 to 20 cm (4 to 8 in) tall from stems which grow just under the surface of the ground. The leaves are hollow at the bases.[3] The female stems produce strobili up to 3 cm (1 in)long.[6][7][8]
Diphasiastrum alpinum may hybridize with Diphasiastrum sitchense.[3]
