which the succeeding generation is born. These minute 
     
     vehicles of generation are produced in flattened, kidney- 
     
     shaped, leathery sporanges or seed cases (Figure I) situated 
     
     in the axils of the simple leaves, and when ripe separating 
     
     into two valves, thereby liberating the tiny yellow spores. 
     
     These spores, being rich in oil, are highly inflammable, and 
     
     are in consequence used in stage effects to produce mimic 
     
     lightning. 
     
    

    
     The several species are arranged in three groups 
     
     according to the shape of the leaves protecting the 
     
     spore cases, and their position on the plant. 
     
    

    
     In the first class are those species in which the 
     
     leaves covering the spore cases are similar to those 
     
     of the stem. Of these we have two on Prince Edward 
     
     Island - (l) the Shining Club—moss (Lycooodium 
     
     lucidulum, Michxi) (Pig. 2) with its dark green, 
     
     shining leaves, turned downwards, and arranged in 
     
     alternately longer and shorter 
     
     series -and, (2) the Brittle-stemmed 
     
     Club~moss (E. inundatum, inundatus - 
     
     over-flowed) of the bogs. In this 
     
     latter the leaves at the end of the 
     
     branches are gathered into a 
     
     slightly club—shaped spike, suggest- Fk"LFME£$::¥E:mL‘

     moss." (I may here say that the botanical name, Lycopodium, 
     
     meaning wolf's foot, is supposed to have been given to the . \ 
     
     family because of the fancied resemblance of the ‘ 
     
    
   
   
    
     branching roots of some of the speCies to a wolf's 
     
    

    
     foot — an evidence of an easily satisfied imagination.) 
     
     In the remaining species the spore cases are in 
     
    

    
     the axils of yellowish, scale-like leaves, broader and 
     
    

    
     shorter than those of the stem, and arranged in cone-

     the fertile branches have minute leaves, and hence the 
     
     spore-bearing spikes appear long stalked. Illustrating 
     
     the second class, and represented in Figure 3, is the Ground Pine (§_obscurum E.) 
     
     a bushy little growth like a miniature tree, so often associated with mayflowers 
     
     in bouquets. Our Figures 4 and 5 represent the third and last division. The 
     
     former is the Running Pine, our commonest one like long, thick wooly cords, irreg- 
     
     ularly and coarsely branched, the fertile part like two or more elongated cones. 
     
     This plant is well named a clavatum E. ("set with studs of gold.") 
     
    

    
     The last species illustrated (Fig.5) is the Trailing Christmas-green, which 
     
     might well be called Cedar Club—moss because of its flattened fan-shaped branches 
     
     by which it is easily distinguished.
