THE TRAILING LYCOPODIUMS. 97 



The most striking difference between these two 

 species, however, is found in the fruiting portions. In 

 Lycopodimn alpinutn they are raised somewhat above the 

 foliage on thick branch-like stalks with appressed leaves, 

 but in the present form they are borne on slender 

 peduncles two or three inches long, which bear only 

 scattered, slender, spreading leaves. In Lycopodium 

 alpinnni there may be some doubts as to 

 whether there is any peduncle at all to the 

 catkins ; but no doubt whatever exists regard- 

 ing their occurrence in Lycopodium sabincB' 

 folium. The spikes are an inch or less in 

 length, slender, and the whorls of leaves on 

 the peduncles below the spike have the odd 

 trick of producing sporangia. When the 

 spores are ripe the sporophylls are usually re- 

 flexed as in Lycopodium alpinum. The cat- 

 kins are usually borne singly, but there are Branch of 



Lycopodium 



occasionally tu'o or three together. Like sabin(efoiium. 

 Lycopodium complanatum, the old branches produce new 

 branchlets and new catkins for at least two years in suc- 

 cession. 



The savin-leaved club-moss is named for its resem- 

 blance to the juniper {Juniperus sabind). Its range is 

 given as from Prince Edward Island, northern New 

 England, and Ontario, northward. In geographical 

 position it lies between Lycopodium complanatum and 

 Lycopodium alpinum, and the three may not improbably 

 represent three strongl}^ marked races of the same 

 species. It is of interest to note that while Lycopodium 

 alpinum ranges around the globe in high latitudes, 

 Lycopodium sabincEfolium is not found in the Old World, 

 although there is a variety much like it in Japan called 

 Lycopodium Nikoense.
