TOPOGRAPHY OF BLAKENEY POINT.

future development is uncertain. Should its mouth be effectually 
cut off from the sea by the throwing up of an apposition bank, 
it would either remain a low indefinitely, or, if the outer 
embryo dunes did not develop too rapidly and so cut off 
supplies of sand, it might become dotted over with Psamma 
dunes. On the other hand, should it remain tidal there is 
the possibility that it may develop a salt marsh — not, in all 
probability, a muddy marsh like the Pelvetia Marsh to its 
south, but on present conditions a salt marsh of the sandy 
order.

The following preliminary account of the Flora of Blakeney 
Point and Shingle Bank is the result of work carried out 
during the past three years as a member of Professor Oliver’s 
ecological party. The author is deeply indebted to Professor 
Oliver, not only for valuable advice and criticism on many 
points, but also indirectly to his stimulating influence through 
the whole co-operative effort of which the present paper is but 
a single outcome. 
For the investigation of the area in question the work was 
divided up into separate parts, each being allotted to a different 
section, and it is to the other members of the “ Floristic 
Section ” that the writer’s thanks are due for their assistance 
in the field. 
For an account of the topography of the district dealt with 
in the following communication the reader is referred to the 
preceding section of this paper.
