The effect of variable mois- 

 ture supply and highly acid 

 soil is seen in the stunted 

 and rather defective stands 

 of cypress occurring in the 

 ponds distributed thickly 

 over the region from South 

 Carolina to Florida. Here 

 the starved cypress hi its 

 extreme form occurs and is 

 commonly known as the 

 "pond" cypress. In these 

 situations cypress has practi- 



cally no compe titor, although

 & spruce pine.
