VEGETATION OF BLAKENEY POINT. 
Description of Figures 10—17 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 Runiex 
trigranulatus, Silene maritima, and Arenaria peploides ; on 
the crest, at the extreme right and left, bushes of Suceda. 
Fig. 1 1. — The sea face of the Hood where the dunes abut on 
the main shingle bank. The tussocks consist almost entirely of 
Gorynephorus canescens. 
Fig. 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. 
Fig. 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. 
Fig. 14. — Part of the sea front of the dunes on the Headland. 
Beyond the inlet are the outer systems of embryonic Psannna 
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. 
Fig. 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. 
Fig. 16. — Open association of Rumex trigranulatus and 
Silene maritima. Main bank near the Watch House. 
Fig. 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.
