508 VEGETATION OF BLAKENEY POINT. 
the majority of localities but also the bulk of individuals, were 
all on the landward edge of the nearest line of Suceda bushes, 
and in most' cases quite close to them. 
To anticipate slightly with respect to the lateral hooks (cf. 
p. 514); the distribution of the Artemisia there is in general 
very clearly and sharply defined, forming a zone between the 
outer edge of the Suceda bushes and the salt marsh itself, with 
a few plants occasionally intermingled. The close association, 
(p. 507) usually in the same definite relative position obtaining 
between these two species on the main bank as on the laterals, 
impresses us forcibly with the fact that we have here no mere 
coincidence but a clear indication that these plants formerly 
occupied such places at the edge of the salt marsh now over- 
whelmed by the landward advance of the shingle. 
We can, therefore, conclude that the halophytic flora of the 
main bank is to be regarded as comprised of relicts, and the 
data for this can be summarised as under : — 
(a) The relative positions of the Suceda , Artemisia (and 
perhaps Obione and Festuca) which obtain in un- 
disturbed marshes are retained by the relicts on the 
mobile shingle. 
( b ) Instances of recent overwhelming are not infrequent at 
the edge. 
(c) The relicts occur chiefly where marshes now fringe the 
bank, and are mostly distributed towards the landward 
edge. 
(d) The absence of Suceda opposite hooks due to “ hook 
sliding.” (Oliver, loc. cit.,p. 92). 
(e) Plants of Artemisia, Statice and Plantago close to the 
edge still have their roots in the marsh soil below. 
The Arenicolous Element. 
Dune plants are likewise represented in the shingle flora, and 
some of these, at all events, are to be regarded as colonists. At 
its distal extremity (the Headland) the shingle bank is almost 
completely covered by dunes, and transitions between these 
and the shingle formation are to be found, and will be con- 
sidered in connection with the dune formation. The following
