The relationship of the present Flora of the Norwegian Polar Sea to thai of the other parts of the Arctic Sea, the Northern Atlantic, and the northern Pacific, will be seen from this table : The Norwegian Polar Sea lias in common with the Greenland Sea. with the White Sea ami the western Murman Sea with the eastern Murman Sea with the Kara Sea with the Siberian Sea with the American Arctic Sea with Baffin Bay with the northern Atlantic with the northern Pacific. 13 28 .31 'J 23 21(24) 13(14) 11 9(10) 1 8 6 1 D 4 2 34(35) 18 69 62 29 23(32) 21(24) 12 68 15 15 - i -: 164 32 35 » 30i 1-J ;' >• 7,.r. o 13 I 84 » 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 tie 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 eomprehended within the region of the arctic Flora, but, the greater part of the elements of its Flora being natives of the northern Atlant
