374 PROCEEDINGS OF THE ACADEMY OP [Aug., 



the same type of salt marsh vegetation exists as far north as New York 

 City. 



Early in the field work it became apparent that my entire time and 

 attention could be devoted to the salt marsh and pond vegetation of 

 the region covered by this phytogeographic survey, for a study of the 

 flora of the sea beaches and sand dunes, which are not extensive on the 

 northern New Jersey coast, revealed the fact that the same association 

 of shore and dune plants existed north of Manasquan Inlet as south of 

 it as far as Cape May. The vegetation of the salt marshes, salt ponds 

 and fresh water ponds of the northern New Jersey coast present so 

 many features of interest that it was fortunate that my undivided 

 attention could be given to its study, so that the dune flora will be 

 mentioned in what follows only when necessary in elucidating the 

 composition of juxtaposed plant formations. 



Physiography of the Region. 



No mention is made of the ponds which are characteristic of the 

 northern shore of New Jersey in the works that have been published 

 on the physiography of New Jersey. Several of them at Ocean Grove 

 and Asbury Park have been surrounded by embankments, and are 

 used for pleasure craft and for winter and summer carnivals. Begin- 

 ning at Manasquan Inlet in the south and traveling northward, one 

 encounters the following bodies of water, which will be designated as 

 open or closed to the ocean, and therefore fresh or salt : 3 



Manasquan Inlet (open and salt). 



Newberry Lake = Stockton Lake (open and salt, connected with 

 Manasquan River). 



Wreck Pond (open and salt in 1908; closed during the summer of 

 1909 and fresh until August 13, 1909, when it was opened to let in 

 the salt water). 



Spring Lake (closed and fresh). 



Como Lake (closed and fresh). 



Silver Lake (closed and fresh; pleasure lake). 



Shark River Inlet (open, with strong tidal movement to and from 

 the sea; closed on July 23, 1909, by the formation of a sand bar during 

 a southeast storm; opened again August 12, 1909). 



Sylvan Lake = Duck Pond (closed and fresh, but connected with 

 sea at very high tides). 



3 The following maps, published under the auspices of the Geological Survey 

 of New Jersey, will be found useful: Atlas Sheet No. 9, Monmouth Shore, 1902; 

 Navesink Sheet, 1901; Long Branch Sheet, 1901; Shark River Sheet, 1903.
