32 VEGETATION OF BLAKENEY POINT. 



wanting. A similar phenomenon is presented by a small area 

 on the crest of the eighth bank, which lies a little below the 

 general level, and has not yet become a closed turf ; here we 

 find Statice binervosa, Frankenia Icevis and the usual 

 associates, together with Spergnlaria salina. It would appear 

 that the amount of soil accumulated on the shingle was as 

 potent a factor as the actual level, and such accumulation will, 

 naturally, be greatest on the flat expanse which forms what we 

 have termed the crest, where the soil reaches a depth of 

 about two inches. 



In the following list of plants observed in the Crest 

 association, the numbers indicate the banks on which the 

 species occur ; where no number follows, presence on all the 

 banks (with the exception of No. 5) is implied.

(5.) The High Elbow. 



The association of the high elbows, whilst including several 

 of the species found on the major part of the crest, comprises 

 many which do not grow elsewhere, and we shall include in 

 this category the high ridge-like portion of bank one, which,
