Many of the above species are more common southward and 

 westward, and do not range much farther northeast than Athens. 



At many points in the gray gravelly and sandy lands the under- 

 lying rock is hard enough to resist disintegration and becomes ex- 

 posed on the surface. On these granite outcrops, and particularly 

 around their edges, where there is apt to be more or less moisture, 

 are found some rather interesting plants, among them being the 

 following : 



Cheilanthes lanosa (Mx.) Watt. Arabis Virginiea (L.) Trel. 



Woodsia obtusa (Spreng.) Torr. DiamorpJta pusilla Nutt. 



Fimbristylis autuuuialis (L.) R. & Saxifraga Virginicusis Mx.

Plantago elongata Pursh. 



Valerianella radiata (L.) Dufr. 



Still another peculiar flora is found in deposits of dry sand along 

 the rivers at a few points. The species frequenting this sand are 

 quite few, on account of the very small relative extent of these 

 deposits. I have noticed the following psammophiious species 

 along the two rivers in Clarke Co.: 



Pteris aquilina L. 



* Yucea filamentosa L. 

 Lupinus perennis L. 

 Aseyrum hyperieoides L.

I have found all of these, with the exception of Lupinus, much 



more abundant in south Georgia, where the soil is nearly all sand. 



Lastly may be considered the plants of fields, roadsides and
