times in association with C. semidecandrum) is characteristic 

 of the older, and Glaux maritima of the more recently formed. 

 To revert to our intermediate " Yankee " shingle bank. The 

 commonest species of the crest are Arenaria peploides, Armeria 

 maritima, and Silene maritima. Glaucium luteum is entirely 

 absent, whilst Rumex trigranulatus is only occasional. The 

 increase of stability here, as compared with the main bank, is 

 marked by the presence of such species as Rumex acetosella, 

 Plantago Coronopus, Lotus corniculatus, and Filago minima. 

 The near neighbourhood of the dunes explains the presence 

 in the list which follows of several psammophytes, such as 

 Phleum arenarium and Stellaria Borceana.
