Harper : Flora of Middle Georgia 



about 955b are known from the region of the northern manuals, 

 and the remaining 556 are mostly either recently described or re- 

 cently introduced, or species of very restricted range. 



A little study of the plants of the region under consideration 

 shows that they may be divided according to habitat into seven or 

 eight well-marked principal groups. These groups overlap each 

 other somewhat, but not as much as might be expected. In the 

 following lists of plants I have prefixed an asterisk to those species 

 which are mentioned in more than one list, to give some idea of 

 the extent of overlapping. 



Taking up the various floral areas in the order of their humid- 

 ity, the swamps, bogs, meadows and marshes may be considered 

 first. In the region about Athens these are of very small extent, 

 owing chiefly to the narrowness and steepness of the valleys, and 

 the number of hydrophytic species is correspondingly small. The 

 following have been observed mostly in the meadows along Tan- 

 yard Branch in Athens and in the Sandy Creek marsh just north 

 of the city :
