Under the original name Lycopodium complanatum, this was an inclusive superspecies that included a number of other species now known to be biologically separate. DistributionAs the species is currently recognized, it has been found in Canada, Greenland, northern and central Europe including montane regions of the British Isles, Russia, China, Japan, India, Thailand, and the northern United States.[6][7][3][8] DescriptionDiphasiastrum complanatum is a perennial herb spreading by means of stolons that run along the surface of the ground. Above-ground stems tend to branch within the same geometric plane (hence the specific epithet "complanatum," meaning "same plane"). Strobili are vertical borne in groups of up to 4 at the ends of some of the branches.[9]References1. ^Tropicos {{Taxonbar|from=Q787930}}{{Lycophyte-stub}}2. ^The Plant List 3. ^1 Family Lycopodiaceae, genus Lycopodium; world species list 4. ^Holub, Josef Ludwig. 1975.
