BOTANICAL SURVEY OF DISMAL SWAMP REGION. 



The respectively chiefly tropical ami chiefly extratropical families 

 of the flora are indicate*] in the table, the former by an affixed (T), 

 the latter (E). Families of which the majority of species are Ameri- 

 can are designated (TA) or (EA) as the case may be. Extratropical 

 families that are more strongly developed in the northern than in the 

 southern hemisphere are marked (Eli). It may be mentioned that 

 the number of families and of genera recognized in the following list 

 is somewhat larger than would be the case if the limits of families 

 and genera, as defined in most standard systematic works, had been 

 followed.
