58 VEGETATION OF BLAKENEY POINT. 



DESCRIPTION OF FIGURES 1017 ON PLATE I. 



FIG. 10. Zonation on the W. slope of the 7th hook on the 

 " Marams." The main shingle bank stretches across the back 

 of the picture. In the foreground (right) is the edge of the 

 crest, with Triticum, followed (beyond the first Suceda bushes) 

 by the Statice binervosa zone, with low sprawling plants of 

 Obione. Beyond this the Suceda fruticosa zone. Above this, 

 part of the marsh covered by Obione. At the edge of the main 

 bank bushes of Suceda fruticosa, then the horizontal line of 

 drift, and on the back of the bank scattered plants of Rumex 

 trigranulatus, Silene maritima, and Arenaria peploides ; on 

 the crest, at the extreme right and left, bushes of Suceda. 



FlG. 11. The sea face of the Hood where the dunes abut on 

 the main shingle bank. The tussocks consist almost entirely of 

 Corynephorus canescens. 



FlG. 12. The main bank advancing over the last marsh of 

 the " Marams." Note the fans of shingle, the drift lines, the 

 bushes of Suceda fruticosa and Obione portulacoides. 



FlG. 13. The main bank advancing over the crest of the 4th 

 lateral hook on the " Marams " ; grasses on the right-hand 

 side of crest are seen colonising the advancing shingle. 



FlG. 14. Part of the sea front of the dunes on the Headland. 

 Beyond the inlet are the outer systems of embryonic Psamma 

 dunes. On the left, part of the Beacon Hills range. Near the 

 centre of the foreground is the drift line, with plants of Salsola 

 Kali and Cakile. 



FlG. 15. The main shingle bank where the dunes of the 

 Long Hills run on to it. In the foreground is a depression 

 with low-growing bushes of Suceda fruticosa, between which 

 are plants of Statice reticulata (not seen in the picture) ; then, 

 two-thirds up the picture, the Statice binervosa zone. Beyond 

 are sand dunes. 



FlG. 16. Open association of Rumex trigranulatus and 

 Silene maritima. Main bank near the Watch House. 



FlG. 17. Flowering specimen of Mertensia maritima on 

 the main bank ; some of its leaves are nibbled by rabbits. The 

 two darker veined leaves on the right, belong to a seedling of 

 Senecio Jacobcea.
