H. JONSSON: MARINE ALGAL VEGETATION 



are rocks, there vegetation is sure to occur. At Vik in Myrdal near 

 the southern point of Iceland there was, for instance, a poor vege- 

 tation on the rocks. 



When one considers how great is the extent of Iceland's coast- 

 line, one cannot expect this to be sufficiently elucidated as re- 

 gards the distribution of marine algae by the few and scattered 

 investigations which have been undertaken. For a long time, then, 

 I nourished the hope of being able to undertake further investiga- 

 tions, and therefore constantly deferred publishing a comprehensive 

 description of the algal vegetation. Now, however, I have decided 

 to delay no longer and hope in the future to be able to make a 

 more extensive contribution in several respects towards the eluci- 

 dation of the algal vegetation.
