SPECIES MORE OR LESS ABUNDANT IN BOTH ZONES : Populus

 Quercus nana (Marsh.) Sarg., Sassafras Sassafras (L.) Karst., 

 Liquiddmbar Styraciflua L,., Prunus serotina Ehrh., Acer 

 rubrum L., Nyssa sylvatica Marsh. 



It may be noted that three species (Quercus alba, Q. coccinea 

 and Q. velutina) are listed as characteristic trees in both zones. 

 This means that they are so abundant in both that any descrip- 

 tion of the prevailing vegetation in either would be incomplete 

 unless they were mentioned. On the other hand, the species 

 listed as abundant in both zones are equally wide in their distri- 

 bution, but none of them is so abundant as to be characteristic,
