VEGETATION OF BLAKENEY POINT. 
the two arms of which are directed landwards. F rom two sides 
the dune slopes towards this hollow, which is closed on the third 
by shingle, and thus forms a comparatively sheltered habitat. 
The face directed towards the main shingle bank is further 
protected as to its lower slopes by a thick growth of Sueeda 
bushes at the western end, and by a group of small isolated 
dunes towards the east. 
One of the chief interests of this spot is the occurrence here 
of Corynephorus canescens (fig. 11), which lines the lee slopes 
of the depression, and also occupies the sheltered patches 
resulting from the Sucedas and dunes referred to above. (Text 
fig. 9.) In view of what has been already said as to the 
preference of Carex arenaria for sheltered situations, it is 
interesting to note that it is to these parts of the Hood that this 
plant is .chiefly confined ; they are also both present in a sudden 
dip or dell on the northern border of the Hood, which likewise 
affords them shelter. 
As on the Long Hills, Agrostis maritima and Plantago 
Coronopus f. pygmcea are found on the shallow sand which 
borders the shingle where it is laid bare by the central depres- 
sion ; but Filago minima , which in the former locality was 
associated with them, is here rare. Next to the Agrostis- 
Plantago association, and between it and the dune, is a small 
area of/ uncus maritimus, which, together with its accompanying 
species, will be dealt wiith in the section on the Salt-Marsh 
Formation. 
On the whole the Hood probably represents much the same 
stage in dune colonisation as is exhibited over the greater part 
of the Long Hills. The latter support a larger number of 
species which can probably be referred to their greater extent ; 
there are, however, several species present on the Hood which 
are not found in the other locality, the most noteworthy being 
Aspidium filix-fcemina, Corynephorus canescens, Luziila 
campestris, and Veronica officinalis, whilst at the same time 
the ephemerals in general are less common, and Phleum 
arenarium appears to be absent. 
From a consideration of these facts, and from the more
