198 KJELLMAN, THE ALG OF THE ARCTIC SEA. 
such organs in July and August at Nordlanden and Finmarken, in July on the west 
coast of Novaya Zemlya, and a form which is nearest related to f. arctica at the end 
of July at Novaya Zemlya. Of f. abbreviata I have seen only sterile specimens. 
Geogr. Distrib. It is known both from the Atlantic and the arctic region of the 
Polar Sea. In the latter it has but a limited distribution, being probably a form 
that has immigrated there. It is not known from the Kara Sea, the Siberian Sea, and 
the American Arctic Sea. If it occurs in Baffin Bay, it must be very local and scarce. 
The only notice of its occurring there is by LyncByr, who alleges having seen speci- 
mens from that sea in the herbaria of Fasricrus and Giesexe. During the numerous 
expeditions which have in later times visited those waters, this plant has not been met 
with, as far as I know. Its maximum of frequency is on the north-west coast of 
Norway. The most northern locality where it has been observed is the coast of 
Spitzbergen. 
Localities: The Norwegian Polar Sea: Nordlanden (f. abbreviata, f. typica and f. 
angusta) common and abundant; Tromsé amt (f. grandifrons and f. typica), the latter 
form abundant and common; Finmarken (f. ¢ypica) common and abundant, at Maasé, 
Gjesver, the south coast of Magerd, and Oxfjord; f. grandifrons local and more scarce 
at Maas6é and Gjesvwr. 
The Greenland Sea: the coast of Spitzbergen (f. arctica), local and probably scarce. 
The Murman Sea: the coasts of Russian Lapland and Cisuralian Samoyede-land, 
local and scarce; the west coast of Novaya Zemlya and Waygats; probably everywhere 
forms most nearly allied to f. angusta and f. arctica. Cp. Gopi and KseLuMan |. ¢. 
The White Sea: common and plentiful, probably f. angusta and arctica. 
Baffin Bay: the coasts of Greenland, according to LYNGBYE.
