The 53 species 50 of plants found in Magnolia bogs in the 

 vicinity of the District of Columbia added to the 71 occur- 

 ring elsewhere in the Coastal Plain region to the eastward 60 

 that are identical with species listed by Stone as character- 

 istic of the Pine Barren flora of New Jersey make up 70.5 per 

 cent 01 of that list (total, 173). 



58 Polygala lutea, Polygala cruclata, Rhexia mariana, and Xyris caro- 

 liniana are species recorded by Brereton, but included in the list of plants 

 not found by Ward (Flora pp. 12-13), which have since been collected in 

 Magnolia bogs. May we not also hope to discover in these bogs other 

 plants mentioned, and with little doubt seen, by the older writers such 

 as Chamaedaphne calyculata, Trichostema lineare, Arethusa bulbosa and 

 Pogonia divaricata? 



* A number of other characteristic species are found in eastern Virginia. 

 Three occurring in the Norfolk-Virginia Beach area may be mentioned : 

 Nymphaea americana (variegata), Hudsonia ericoides and Aster gracilis. 



«This fact undermines considerable speculation based on the supposed 

 absence of Pine Barren plants from Maryland and Delaware. For instance 

 the following from Harshberger (Dr. J. W., The Vegetation of the New 

 Jersey Pine Barrens, 1916, p. 2) : "This isolated island of pine-barren 

 plants was removed still further from contact with the Southern pine-bar- 

 rens by the unequal depression of the coastal plain, so that with the excep- 

 tion of the island vegetation, the typic coastal plain plants were extermi- 

 nated in the depressed portion of the plain in Delaware and Mary- 

 land • * * for Shreve has indicated the almost utter lack of pine- 

 barren plants in Maryland."
