mark '). I have only to add here that of the Fucacew and Laminariacee the following 
species ought to be regarded as characteristic of this Flora: 
Himanthalia lorea ’), Pelvetia canaliculata, 
Halidrys siliquosa *), Alaria esculenta *), 
Ozothallia nodosa, »  membranacea, 
Fucus serratus, Phyllaria dermatodea, 
» vesiculosus, Laminaria saccharina, 
» spiralis, » Clustoni, 
»  edentatus, » digitata, 
»  filiformis, Chorda filum. 
The relationship of the present Flora of the Norwegian Polar Sea to that of the 
other parts of the Arctic Sea, the Northern Atlantic, and the northern Pacific, will be 
seen from this table:

These figures clearly show that the Flora of the Norwegian Polar Sea has the 
greatest affinity to that of the northern Atlantic. 
Thus it has been demonstrated by the examination now carried out, that this 
Flora possesses of old a number of polar or arctic elements, that other elements have 
been added partly by the forming of new species partly by immigrations from the 
south, and that these younger elements, being considerably preponderant, determine 
chiefly the general character of the present Flora. On this account, the Norwegian 
Polar Sea ought not to be comprehended within the region of the arctic Flora, but, 
the greater part of the elements of its Flora being natives of the northern Atlantic 
and having been transplanted from there to the north and north-west coast of Norway, 
it should be referred to the region of the Atlantic Flora. Though the other parts of 
the Arctic Sea certainly have no perfectly uniform Flora, their marine vegetation agrees 
in these respects, viz. that a considerable number of its elements occur everywhere, that
