THE TRAILING LYCOPODIUMS. 



species, tlie supply coming mostly from Sweden, Russia, 

 and Switzerland. It is obtained by gather- 

 ing the spikes just before the spores are 

 shed, and collecting the powder in papers. 



Occasionally a form of this species is 

 found in which there is but one strobile 

 on each peduncle. This has been named 

 variety monostacJiyon. It is usually found 

 in dryish situations, and its form is appar- 

 ently due to a lack of some of the normal 

 plant's requirements. While the variety 

 usually produces but one strobile to each 

 spike, it is possible to find plants with 

 single strobiles near the growing end, and, 

 farther back, peduncles bearing two or more 

 strobiles. 



This plant is one of those in greatest 

 demand for holiday decorations, and the 

 ^ij demand for it has made it rare in many 

 localities. Fortunately, owing to its 

 manner of rooting, the whole plant is 

 seldom pulled up, and the fragments 

 left behind may ultimately produce 

 thrifty plants, so that it is likely to be 

 a long time before it entirely disappears 

 from a locality. 



This is the club-moss par excellence, 

 as its specific name indicates. In 

 America, however, it is better known 

 as " groimd-pine," "running-pine," or 

 " trailing Christmas green." Among Old 

 World names for it may be mentioned
