Summary. The sand-hill vegetation is more like that of the 

 dry pine-barrens than any other previously discussed. A little 

 more than half of the species in each of these habitats are com- 

 mon to both, but their order of abundance is very different in the 

 two lists, and if only the 25 most abundant species in each were 

 considered there would be very few in common. The proportion 

 of trees, shrubs, and herbs is almost identical in the two groups. 



Quercus Catesbcsi probably exceeds in numbers all other trees 

 on the sand-hills combined. It would be hard to find a Georgia 

 sand-hill without this tree and Eriogonum tomentosum, the most 

 abundant herb. An interesting feature of the sand-hill flora is 

 the occurrence of three rare shrubs, Chrysoma, Clinopodium, and 

 Polygonella Croomii, belonging to families which are mostly 

 herbaceous.
