132 FERNS AND THEIR ALLIES 



The leaves are about eight-ranked, rigid, dark 

 green, glossy, entire or sometimes slightly 

 toothed, ascending, pointed and somewhat 

 crowded. 



Fir Club-Moss is usually found only in high 

 altitudes, and can be termed rare. 



It somewhat resembles Swamp Evergreen ; 

 but in Fir Club-Moss, the forking of the stems 

 near the top, and the level-topped clusters, to- 

 gether with its smaller size, may aid in deter- 

 mining the species. Its leaves also are more 

 nearly uniform in size. 



The leaves of this and L. lucidulnm often 

 bear gemmae, or buds, by which the plants are 

 propagated. 



The spore-cases are borne in the axils of the 

 ordinary leaves ; they mature from August to 

 October. 



COMMON CLUB-MOSS. 



Lycopodium davatum. 



Stems creeping on the surface of the ground ; 

 branches similar, ascending, short, and crowded 

 with linear-awl-shaped, incurved or spreading 

 light green leaves, which are tipped with a fine 

 bristle. 



This species grows in dry, shaded pastures 

 and woods, and is very common. It is some- 

 times called Running Pine.
