CLUB-MOSS FAMILY 131 



The fertile spikes are sessile, scaly, one inch 

 long, solitary, and several on each plant. They 

 mature in July. 



SWAMP EVERGREEN. 



Lycopodium lucid ulum. 



Stems ascending, from five to ten inches long, 

 and two or three times forked, usually below the 

 middle. 



The leaves are minutely toothed, pointed, 

 spreading or often defiexed, and in eight rows. 

 They are arranged in alternate series of longer 

 and shorter lengths, and are somewhat larger 

 than is common to this genus. 



It is sometimes called Shining Club-Moss, pre- 

 sumably because of its glossy, dark green leaves. 

 Swamp Evergreen grows in cold, damp woods, 

 and although it can be found usually in its favor- 

 ite haunt, it is not so common as some others 

 of this group. 



The spore-cases are borne in the axils of the 

 leaves near the summit of the stem. They can 

 be found in good condition from August until 

 October, and frequently persist a year or two. 



FIR CLUB-MOSS. 



Lycopodium Selago. 



Stems erect, forked by pairs, forming a level- 

 topped cluster from three to six inches high.
