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, 13 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 Suceda 

 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 (some-

 N.W. face of this bank.
