70 THE PLANT LIFE OF MARYLAND 



The Coastal Zone. 



Among the plants of the Coastal Zone above listed a few are quite 

 common throughout the Zone and leave off abruptly along its inner 

 edge, for example, Liquidambar styraciflua, Magnolia virginiana, 

 Clethra alnifolia, and Quercus digitata. Other species are less 

 abundant than these but nevertheless occur throughout the Zone and 

 are limited quite as sharply in their distribution by the "Fall-line.'' 

 The only Coastal Zone plants which occur throughout the Zone are 

 the following : 



Woodwardia virginica 



Woodwardia areolata 

 Lycopodium inundatum 

 Eriocaulon decangular e 

 Myrica carolinensis 

 Quercus digitata 

 Quercus jjhellos* 

 Magnolia virginiana 

 Itea virginica 

 Liquidambar styraciflua 

 Euphorb ia ipeca cuanhae 

 Ilex opaca 

 Ilex glabra 

 Clethra alnifolia 

 Leucothoe racemosa 

 Pieris mariana 

 Sabbatia dodecandra 

 Tecoma radicans* 

 Viburnum nudum 

 Lonicera sempervirens 

 Eupatorium hyssopifoliu m 



Since the entire length of the "Fall-line" in Maryland is but Da 

 miles, it becomes of interest to inquire into the distribution of the 



♦Species thus designated occur for ]n to 20 miles above the "Fall-line" 

 along the Potomac River.
