PHYTOGEOGRAPHICAL PROBLEMS IN SVALBARD 107 



by where, they occur today. This leads us, for example, to the conclusion that 

 there have been conditions for plant life both in refugia along the coast and 

 on nunataks in the inner fjord districts. The plants common to the total area 

 are probably of a very great age but the endemic species mentioned above 

 must be the result of an evolution after the Tertiary.
