which is found on Long Island, N. Y., southern Connecticut 

 and Rhode Island and eastern Massachusetts — ^479 species, f 



(4) Species of local distribution, restricted to New Jersey 

 and portions of the immediately adjacent States lying within the 

 coastal plain — 31 species. 



Plants op Wipe Range. — These species may be divided into 

 three groups, as follows : 



Ranging throughout North America, • • 22 



Newfoundland — New Brunswick on the north to Virginia— Florida ..on 



the south, 420 



Maine — Vermont to Virginia — Florida, 300 



As already said, many of these plants barely enter our region 

 on the northwest, so that the lower part of New Jersey is really 

 on the southern boundary of their range, although since they 

 follow the trend O'f the mountains to the southwest the actual 

 southern limit of their range, given in the Manuals, is far down 

 in the southern States. The most surprising fact in the study of 

 these ranges is the large number of plants which range from the 

 far north all the way to Florida and yet are rare or absent in the 

 lower part of the New Jersey coastal plain, but the brief data 

 of the Manuals is hardly sufficient for detailed studies of distribu- 

 tion and many of them may be quite as scarce in Florida as they 

 are in southern New Jersey. 



The Northern Element. — ^A second group of our New 

 Jersey coastal plain plants includes those which find the absolute 

 southern limit of their range in this region or close to it, while 

 they extend north to Maine or the Canadian provinces. They 

 may be divided as follows : 



Canadian Provinces to New Jersey, 60 



Maine to New Jersey, 18 



Vermont or New Hampshire to New Jersey, 3 



Canadian Provinces to Delaware or Maryland, 27 



Maine to Delaware or Maryland, 13

as I have employed in the following pages. He likewise considers all the 

 species native to the region, which, as I have stated elsewhere, is the only 

 way to logically discuss the floral relationship of a district.
