LYCOPODIUM CLAVATUM (The Common 

 Club-Moss) 



SPOROPH YTE 



I. In a well-grown specimen of this plant, which is 

 commonly to be found on moorland hills, recognize the 

 following external characters : 



1. The stem, often extended to a great length, is 

 creeping, and frequently branched, apparently in a 

 monopodial manner (for particulars see p. 283) : the 

 stronger branches are also creeping, the weaker branches 

 ascending. 



2. From the under side of the stem roots are de- 

 veloped, which frequently, but not always, appear at 

 points where the stem branches. The roots them- 

 selves are branched dichotomously, but the limbs of the 

 dichotomy may develop either equally or unequally. 



3. The stem is covered with leaves, which are 

 simple in form, and linear, witli ciliate margin, and 

 have a long awn-like apex. The arrangement of the 

 leaves is complicated, and has been described as being 

 partly in whorls, partly spiral : the number of members 

 of the whorls is variable, as is also the angle of 

 divergence of the spirally-arranged leaves. 



4. The fertile branches or cones, which bear
