Diphasiastrum complanatum,[4] common names groundcedar,[5] creeping jenny, or northern running-pine, is a species of clubmoss native to dry coniferous forests in colder northerly parts of the world. Under the original name Lycopodium complanatum, this was an inclusive superspecies that included a number of other species now known to be biologically separate. This plant is an evergreen, perennial pteridophyte. The spores are produced June to September.[6]

Description
Diphasiastrum 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.[7] The stem can reach even over 100 cm in length with offshoots of 5-30 cm long which are upright that are flat at the top. The leaves are scale-like small and parallel to the stem. The sporangium are in long-stalked densely cylindrical spore cones.[6] The shoots on the horizontal plane can take root and eventually form large colonies. Eino Oinonen studied a clonal colony in Finland which measured 250 m (820 ft) in diameter.[8]
