THE TRAILING LYCOPODIUMS. 93 



the -ground to the exclusion of all else. Because of its 

 use in decorations it is probably oftener seen than any 

 other species. 



Among its common names are " trailing Christmas 

 green," " running-pine," "ground-cedar," and "festoon 

 ground-pine." It shares the name of " creeping jenny," 

 with the common club-moss, and is also known as " hog- 

 bed " and "liberty." Occasionally it is called "princess 

 pine," but this name belongs by right to one of the 

 heathworts. 



The ground-pine is found in the North Temperate 

 Zone of both Hemispheres and has been reported from 

 Madeira, the Azores, Madagascar, Java, Sumatra, New 

 Guinea, and other tropical islands. It is also found in 

 the Andes. Some of the forms from tropical coun- 

 tries are very different in appearance from ours and will 

 doubtless some day be considered distinct species. In 

 North America the plant ranges from the mountains of 

 Georgia to Labrador, Iowa, Washington, and Alaska. 

 In the United States the greater part if not all of the 

 plants belong to the variety flab e Hi for me. As Canada 

 is reached it fades gradually into the type. The range 

 of the variety chdm&cyparissus is usually given as from 

 Maine to Georgia and Minnesota, but it will probably 

 be found to be coextensive with that of the type when 

 it is better known. The plant loves moist, shady 

 woodlands, but may also be found in thickets and 

 pastures, and along roadsides, often in dry situations, 

 especially in upland regions.

In the northern parts of our continent there grows a 

 species of Lycopodium that much resembles Lycopodium
