330 HARPER 



The following genera are represented in the Eastern United 

 States (including South Georgia) by a single widely distributed 

 species which seems to be absent from the Altamaha Grit region. 



Catalpa Negundo 



Phryma Platanus 



Epiphegus Penthorum 



Oxydendrum Fagus 



Decodon Hexalectris 



Sassafras Medeola 



The genera Aster, Solidago, Viola, Acer, Cratcegus, and Scirpus 

 probably have fewer representatives in this region than in any 

 other area of equal extent in temperate Eastern North America, 

 with the possible exception of parts of Florida for Aster and 

 Viola and some of the mountainous regions for Scirpus. 



The following species, not included in the genera in the second 

 list, are known in the upper and lower thirds of the coastal plain 

 of Georgia, but not in the Altamaha Grit region, which is the 

 middle third.
