VEGETATION OF BLAKENEY POINT. 
509 
Sand-dune plants, viz., Carex arenaria, Convolvulus Soldanella, 
Elytnus arenarius, Eryngium niaritimum, Senecio Jacobcea, 
Stellaria Borceana , and Psannna arenaria are all met with 
either as rareties or, in the case of the last, as a not infrequent 
component of the shingle formation." Curiously enough 
Eryngium niaritimum, although typically a psammophyte, is 
only to be found on the shingle and is totally absent from the 
dunes 0 themseves. With the exception of a single meagre 
plant, upon the dunes, the same may also be said of 
Elymus arenarius. 
Typical gravel heath plants are rare (with the exception of 
Festuca rubra referred to above) and few in number ; they 
comprise Lotus corniculatus, Festuca ovina, Holcus lanatus, 
Poa pratensis, Hieracium Pilosella, and perhaps Arrhena- 
therum avenaceum. 
Casuals. 
Besides the normal constituents of the flora, there are here, 
as always, casuals which, regarded from the point of view of a 
shingle beach, are certainly weeds. Of such plants Lychnis 
vespertina and Papaver Rhceas represent the cornfield element 
with a single plant each. (A second specimen of the former 
has been found for the past two years on the shingle near the 
Hood.) Carduus arvensis, Dactylis glomerata, and Tussilago 
Farfara, which are usually to be found in stiff soils, may also be 
placed in the same category. 
Enumeration of species growing on the main shingle bank. 
In all, sixtyplants have, up to the present, been recorded 
for the Blakeney main bank, a complete list of which is 
appended below — 
Agrostis maritima (r.) 
Aira praecox (occ.) 
8 lu view of the name Marams applied to the complex of laterals and marshes 
abutting on the central part of the main bank, and the presence of sand-dnnes on 
both the other aggregations of laterals, viz. : "The Hood "and the Headland, it is 
possible that these Psamma plants may indicate the presence of dunes in former 
times on the more proximal part of the Point. On this conjecture the forward 
movement of the shingle has been accompanied by a similar advance of the sand 
supplies preventing the regeneration of these dunes as they became eroded by 
the wind. 
9 Eryngium is reported as having been quite abundant on the bank in byegoue 
times, aud is now again increasing.
