86 THE PLANT LIFE OF MARYLAND 



in the true Pine Barrens are not found beyond their limits. Pine 

 Barrens occur in the Coastal Plain of New Jersey and Long Island 

 which differ from the true ones in the replacing of Pinus palustris 

 by Pinus rigida, and of the grassy herbaceous vegetation by shrubs. 

 However, many of the plants characteristic of the true Pine Barrens 

 are found in the Barrens of New Jersey, and there, or in Long 

 Island, find their northern limit. 



Neither the true nor the New Jersey type of Pine Barrens is found 

 in Maryland. In the sandy portions of the Western Shore District 

 of the Coastal Zone are areas which resemble the New Jersey 

 Barrens in physiognomy, and in the southern Eastern Shore District 

 are areas which resemble the true Pine Barrens in physiognomy, but 

 nowhere is the characteristic floristic element present. The follow- 

 ing are the species which are, in the main, confined to Pine Barren 

 habitats and are found both in the true and the New Jersey Barrens:
