SHORTER NOTES 



Lycopodium cernuum in Georgia. — While walking from Cuth- 

 bert to Fort Gaines, Georgia, on October 28, 1902, I was sur- 

 prised to find that curious tropical club-moss Lycopodium cernuum 

 L., growing in springy places along the sides of several railroad 

 cuts southwest of Coleman. It was fairly abundant, and though 

 the specimens were rather small (none over a foot in height), 

 many of them were fruiting. As the occurrence of the plant in 

 this manner was of little or no significance from a phytogeo- 

 graphical standpoint, I sought at once to determine its natural 

 habitat, and many promising-looking localities along the railroad 

 for the next few miles were explored, but without success. So 

 how this species came to adopt such an artificial habitat, so 

 remote from any place where it is known to grow naturally, is 

 still a mystery. This branch of the railroad has been in existence 

 for many years, but the country traversed by it is still sparsely 

 settled. 



Lycopodium cernuum does not seem to have been previously 

 reported north of latitude 31 , and it is possible that its native 

 range may be confined to still narrower limits.
