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.
Distribution
As 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]
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.[9]
