tlie arctic region, Odontlialia dentata and Lithothamnion collicido- 
sum are found also in other arctic provinces. 
Of the 11 species fonnd as well in Spitzbergen as in the 
Murman Sea bnt not on the east coast of Greenland i are also 
absent froni the western coast of that country. The 4 others, 
Didyosiphon Jnppuroides, Ehyllopliora Erodiaei, Ceramium rubrum, 
Cdatliromorphum compadum, in all probability will be found there 
yet. The two species, Eylaiella varia and Edocarpus ovatus , that 
are only found in east Gfreenland and Spitzbergen bnt not in 
the southeastern part of the province, probably also will be de- 
tected there. The 8 species froni east Greenland and the south¬ 
eastern district are not very arctic. With one exception, Eami- 
naria saccharina (var.) they are found also in western Greenland. 
5 of them, Scytosiphon lomentarius , Ehyllitis fascia, Ralfsia deusta , 
Fucus vesiculosus, Rhodyynenia palmata are found only in the 
Southern part of the east Greenland-coast, two others, Isthmoplea 
sphaerophora and Sorapion Kjellmani are not found there yet. 
Lastly there are 33 species only found in east Greenland; 
most of these are also known from the western coast of that 
country. 
The 120 species of the Spitzbergen-province are distributed 
as follows: east Greenland has 85, Spitzbergen 64, the Murman 
and White Sea 76. If a comparison of the East-Greenland- 
flora with those of the others parts of the province is made 
after the method I have previously (38, p. 219) proposed, the 
result will be the following:

The series of figures below I have taken froni Ivjellman 
(30), to show how far our knowledge of the East-Greenland-Üora 
has advanced since his work was written. It is easily under- 
stood, in looking at these figures, why Kjellman could say: 
„The scanty notices, t.hat we possess on the marine Vegetation on
