Common throughout in moist pine-barrens, branch-swamps, 

 and cypress ponds, usually with Pinus Elliottii. Noted in 

 every county in our territory; least abundant in screven, 

 emanuel, Montgomery, and the upper part of bulloch, 

 where there are few or no cypress ponds and where this 

 species does not grow in most of the branches as it does 

 on the other side of the Altamaha River. Ranges through- 



. out the pine-barrens of Georgia, including Okefinokee 

 Swamp, and known from a few outlying stations in the 

 upper fourth of the coastal plain. 



Virginia (Dismal Swamp) to Florida and Mississippi, in the 

 coastal plain.

tattnall: Along the Ohoopee River near Ohoopee; coffee: 

 Along Ocmulgee River near Lumber City. More common 

 in the upper third of the coastal plain and northward, 

 particularly in the lime-sink and Palaeozoic regions. 

 Widely distributed in the Eastern United States, but often 

 as an escape from cultivation, so that it is difficult to deter- 

 mine its natural range accurately.
