KJELLMAN, THE ALG^ OF THE ARCTIC SEA. 



Survey of the coinposition 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 foUowing 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 alga? of the Polar 

 Sea and exhibits the outlines of their distribution within the Polar Sea, as understood 

 in the wide sense inentioned 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 coinpo- 

 sition of the vegetation in different parts of the sea-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 seenis 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 GoBi ^).

^) I have not entered into this list some species tliat have been repovted from the Arctic Sea, but seem to 



be iraperfectly known or raost probably incorrectly determined. It will be stated further on which those 



species are. 

 ^) The mark ? iudicates that the oecurrence of the plant within the region is uncertain.
