more or less over tlie whole lower third of the peninsula. Most 

 of these species are restricted to the Cape May District, but a 

 few have spread norlliward in the lower Middle District, and 

 constitute the "Cape May element" referred to under that head — 

 i. e., Piniis scrotina, Paspalum membranaceum, Aristida lanosa, 

 Gymnopogon brcvifolius, Bleocharis tortilis, Hypericum odpres- 

 siim, Gratiola sphaerocarpa, Lobelia puberiila. In the same 

 category should probably be placed Cyperus pseud ovcgetiis, Poly- 

 gala incarnata, and a few other species rare in the Middle Dis- 

 trict and not yet detected on the Cape May peninsula, 



A few of the Cape May plants also spread northward along 

 the coast strip for a short distance. 



All of the plants peculiar to Cape May, which are of southern 

 affinities, are found immediately across the bay in Delaware, 

 where the flora is practically the same.* 



The Cape May flora numbers in all 658 species ; of these there 

 may be deducted as local intrusions 8, leaving 650 species. 



None of the Pine Barren species have been deducted, since 

 they vary so in their abundance in the Cape May district that it 

 is impossible to say which should be regarded as true members 

 of the flora and which as intrusions or relicts. 



Considering the general range of the si>ecies, they fall into the 

 following categories : 



WIDE RANGING. 



Throughout North America, 13 



Canadian Provinces to Virginia-Florida, 182 



Maine to Virginia-Florida, 164
