Material from Kent is available only for the north coast. Careful studies in the Bognor area in 

 September 1969 and in August 1972 failed to reveal plants currently established there. It would 

 have been a surprise to find plants in any part of the Bognor Regis intertidal as it now is. The 

 Robinson material seems unlikely to have come from any depth into the infralittoral. Smith, 

 Sowerby & Johnson's record was probably secondary, although Johnson may have included 

 original observations. 



The Bognor Rocks area has, over the last 250 years, shown considerable change in configura- 

 tion, due to sand-shift and local sea-level changes associated with the slow sinking of SE England. 

 The extent to which the Bognor Rocks break water at full tide, and their accessibility at other 

 states of the tide, have been so much reduced that even at low springs a boat is needed for easy 

 access. Other aspects of the physical environment may have varied, but there may simply no 

 longer exist in this area those conditions of substratum tolerable to Padina.
