The nati\'es in northwest Georgia commonly call R. glabra 

 " red sumac " and R. copalliiia " black sumac," doubtless on ac- 

 count of the difference in color of the fruit. 



Ilex mvrti folia Walt. 



In the swamp of the Suwannee River (rather an unusual habitat 

 for it) in Clinch County I noticed in February, 1904, some speci- 

 mens of this handsome little tree about thirty feet tall, with 

 trunks a foot in diameter, though this species has not hitherto been 

 recognized as a member of our sylva. During the same winter 

 and following spring I noticed other arborescent specimens of it, 

 in pine-barren ponds, in Sumter, Berrien, Lowndes, Clinch, Ware, 

 and other counties in the coastal plain. 



A characteristic feature of this species is that its trunk is never 

 strictly erect, but always ascending or curved. 



Staphvlea tkifolia L. 



This too does not seem to have ever been credited with becom- 

 ing a tree. On January 7, 1904, I found one specimen on the 

 right bank of the Etowah River in Floyd County about four miles 

 above Rome, on the Knox Dolomite (Lower Silurian) formation, 

 which had a straight erect trunk five or six inches in diameter, 

 with the lowest branches about si.x feet from the ground. There 

 were a few shrubby specimens of it near by, but apparently no 

 other arborescent one. 



Specimens of these four little trees formed part of Georgia's 

 exhibit at St. Louis last year, and are now presumabh' in the 

 forestry collection in the state capitol in Atlanta.
