MARYLAND WEATHER SEEVICE 77 



coastal plants of Maryland in the neighboring states, in order to see 

 in how far the same relations of distribution may hold to the north 

 and south. Of the species coextensive with the Coastal Zone all but 

 three are found to the northward only in the Coastal Plain portions 

 of New Jersey and Long Island or in analagous regions in southern 

 New England. The three excepted species are Woodwardia virginica, 

 Lycopodium iiuindatum and Myrica carolinensis, which range west- 

 ward in the northern states as well as southward along the Coastal 

 Plain.* 



To the south, the somewhat scant literature as to the occurrence 

 and distribution of plants would indicate that Clethra alnifolia, 

 Leucothoe racemosa, and Ilex glabra are confined to the Coastal Plain 

 as far as Alabama. A number of others appear to be common in the 

 ( loastal Plain and rare in the Piedmont, as Magnolia virginiana, Ttea 

 virginica, Pieris marianu. Viburnum nudum and Lonicera semper 

 virens. Others range inland above the "Fall-line" in undiminished 

 abundance, as for example Quercus phcllos. Quercus digitata, Her 

 opaca and Liquidambar styrat Iflua, all of which arc found through 

 out the Piedmont of North Carolina (according to Ashe) and 

 throughout Alabama (according to Mohr). 



Of those species which are confined to the Coastal Zone in Mary- 

 land, but are found only in the southern or southeastern part of it. 

 the majority range to the north of Maryland in the Coastal Plain of 

 New Jersey or to Long Island or even as far north as New England. 

 Following are given the northern limit and the known range in 

 Maryland of these species: 



( 'hamaecyparis thyoides 



Northern limit: Massachusetts. 



Maryland: Worcester, Wicomico and Dorchester counties. 



Sagittaria subulata 



Northern limit: New York.

E rin ii Ih us compactus
