34 KJELLMAN,.THE ALG#Z OF THE ARCTIC SEA. 
Survey of the composition of the Flora of the Arctic Sea. 
In order to bring clearly into view the composition of the Flora of the Arctic 
Sea both as a whole and in its differents parts, I have composed the following tables, 
founded on the statements set forth in detail in the special part of the present work. 
In the first of these tables, which gives a list of the hitherto known alge of the Polar 
Sea and exhibits the outlines of their distribution within the Polar Sea, as understood 
in the wide sense mentioned before and without any reference to the geography of 
plants, I have at the same time indicated if a species is known or not from the nor- 
thern part of the Atlantic and of the Pacific. I intend to make use of the materials 
thus brought together, in my researches on the origin of the Arctic Flora and the 
history of its development. An examination of these tables will show that the compo- 
sition of the vegetation in different parts of the seca-region in question is too disparate 
to allow this region to be considered as a unity with regard to its Flora. On this 
account, it seems to me unsuitable and purposeless to attempt drawing up any com- 
parison between this Flora, taken as a whole, and the Flora of other seas. Such a 
comparison will be instituted below with regard to the Arctic Flora, considered as a 
whole from the point of view of the geography of plants. Concerning the arrangement 
of the tables, it may be remarked that I have put together the Western part of the 
Murman Sea and the White Sea, because the vegetations of these two regions present 
a very great resemblance, as is shown by the description of Gost’).

2) I have not entered into this list some species that have been reported from the Arctic Sea, but seem to 
be imperfectly known or most probably incorrectly determined. It will be stated further on which those 
species are. 
3) The mark ? indicates that the occurrence of the plant within the region is uncertain.
