Silene maritima (f.) 
Vicia angustifolia (7, 8 and l) (occ.) 
The Younger Hooks. 
Of the lateral hooks which intervene between the west end 
of the Marams and the distal extremity of the main bank, most 
are of little value in the present consideration, as they are, 
either in whole or in part, covered by portions of the dune 
system. The distal extremity of one of these, however, 
situate at the end of the “ Long Hills,” and which may be 
termed the Yankee bank, 11 is sufficiently unaffected to be of 
value in this connection and is chiefly of interest as furnishing 
us with a younger stage in which the crest has not yet passed 
beyond the condition of an open formation. 
Along either side of this bank is the usual zone of Suceda, 
and just above it towards the base is a clearly-defined zone of 
Statice binervosa, which gets rarer as we pass towards the 
distal end where the shingle is more mobile ; elsewhere it is 
worthy of note that the binervosa zone is intermittent, and that 
the breaks correspond with those positions where the Sneed a 
bushes present gaps, so that the shingle of this zone is there 
unprotected and consequently unstable. Frankenia, which 
usually accompanies this Statice, is absent from the bank 
proper, but where this joins on to another bank at its base a 
depression of stable shingle covered with mud furnishes a 
habitat for Frankenia Icevis, Statice binervosa and S. 
reticulata. These depressions are of frequent occurrence, and 
always correspond to the V-shaped “ low ” where two banks 
join — in some cases cut off by a bridge, in others exposed to 
normal tidal invasion. The floor is covered with low-growing 
Sucedas about 6 inches high, forming “ hummocks,” between 
which grow the Frankenia and Statice reticulata (with 
occasional S. maritima and Salicornia), and at the edges of 
the depression S. binervosa. Where entirely removed from 
tidal action, as in the bare shingle lows of the dune area 
and near the Hood, Plantago Coronopus var. pygmcea (sorae-

N.W. face of this bank.
