Diphasiastrum sitchense, common names Sitka Clubmoss (in English) or Lycopode de Sitka (in French), is a plant species native to northern North America and northeastern Asia. It is known from every province in Canada, plus the US States of Alaska, Oregon, Washington, Idaho, Montana, Maine, New Hampshire, Vermont, and New York.[2] It is also found in Greenland, St. Pierre and Miquelon, Yukon, Japan, and the Kamchatka Peninsula of Asiatic Russia. It can be found in alpine meadows, open rocky barrens, and coniferous woodlands.[3][4]


Diphasiastrum sitchense is a terrestrial herb spreading by stolons running on the surface or the ground or just slightly below the surface. Leaves are appressed, broadly lanceolate, up to 3.2 mm (0.13 inches) long. Strobili are solitary on the ends of shoots.[3][5]
