48 VEGETATION OF BLAKENEY POINT. 



the two arms of which are directed landwards. From 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 Suceda 

 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 maritime! and Plantago 

 Coronopus f. pygincea 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 ofjuncus maritimus, which, together withitsaccompanying 

 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, Luzula 

 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
