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 Spergitlaria 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. 
Agrostis maritima (v.c.) 
Arenaria peploides (7 and 8) (r.) 
Arenaria serpyllifolia (c.) 
Armeria maritima (v.c.)

Cerastium tetrandrum (8, 7, 6, 3 and l) (f.) 
Desmazeria loliacea (3,4, 7) (loc.)

Trifolium striatum (7 and 8) (loc.) 
(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,
