Kearney, T. H m Report on a Botanical Surveyof the 

 DismalSwamp Region. (Contrib. U. S. Nat. Herb. 

 V. 6. Nov. 1901. p. 321—550. pl. 65—77. figg. 51—89. 

 2 maps.) 



This paper describes very thoroughly the climate, geography 

 physiography, geology, soils and the Vegetation of that unique region, 

 the Dismal Swamp, which comprises the whole of Princess Anne and 

 Norfolk counties and the eastern portion of Nansemond county in Virginia, 

 and Currituck, Camden, Pasquotank and Perquimans counties in North 

 Carolina. 



The climate, with the exception of a strip along the outer coast 

 where local conditions produce a desert like Vegetation, is highly favo- 

 rable for plants not adapted to very extreme conditions. It is a „forest 

 climate". 



The physiographic features are beaches and dunes, salt marshes, 

 an area of piain, and an extensive morass region, 3, 900 Square kilo- 

 meters in extent, of very irregulär outline, and partially or totally 

 submerged. 



The striking features of the soil are its high percentage of organic 

 matter and its great acidity, making neutralization necessary for cultural 

 purposes. 



The salt-marsh formations are characterized by Spartina stricta, 

 Juncus roemerianus, Typha, Spartina patens and Baccharis-Hibiscus 

 associations. The sand Strand formations have the following associations. 

 Ammophila-Uniola, occupying the beach and outermost dunes; Myrica 

 (in dry soil) and Juncus dichotomus (in wet soil) on the middle dunes ; 

 and the Quercus virginiana and Strand pine on the inner dunes.
