This plant is perhaps generally known by the name of 
Lycopodium selaginoides, which it formerly bore. It has 
a slender, procumbent, often branched stem, the barren 
branches short and sinuous, the fertile ones ascending or 
erect, and from two to three inches high. They are 
clothed with lance-shaped leaves, of a delicate texture, 
jagged along the margins with spiny teeth ; those on the 
decumbent' stems being shorter, as well as more distant and 
spreading, than those of the fertile branches.
