Species of Lycopodium of North America 163 



part of Willdenow's original material from which he doubtless 

 drew the description of L. sabinaefolinm. The description of the 

 latter with its expression "foliis lanceolatis acutis quadrifariis M in- 

 dicates clearly the form Willdenow had in mind in naming the 

 plant. 



The plants of the Northeast are usually somewhat more slender 



and delicate in habit, with short (2—5 mm.) peduncles. The 



strobiles are sessile upon stronger leafy branches in the North- 

 western forms ; these leafy branches may readily be mistaken for 

 peduncles.
