Simm o ns, Remarks about the Relations of the Floras etc. 
siognomy of the Vegetation at the parts of the european coast wa- 
shed by its waters, but only by its influence upon the conditions 
of life, not directly as a bearer of new immigrants, wliere the 
necessarv ways for the migration of algae are broken. This view 
is supported, f. i., by the flora of the Faeroes, that, in spite of 
very favorable conditions of life, shows a more northerly cha- 
racter in the proportion of brown and red algae (45 and 55 per 
ct.) than even the north e mm ost portion of the norwegian coast 
(41 and 59 per ct.) Even the west Greenland coast lias a great 
number of Southern forms, that do not enter other parts of the 
arctic area (23 species), and here no drift-theories can be brought 
into ac-tion. 
It is previously mentioned that the flora of the Polar Sea 
lias a very niuch greater affinity to that of the Atlantic than 
to that of the Pacific, the percentage being 87 and 44 resp. 
This doubtless will be attributed by the partisans of the drii't- 
theory to the mighty influence of the Gulfstream, for my part 
I seek the solution of this problem in the present or former 
existence of a greater number of coast-ways for immigration 
and further in the previously mentioned circumstance, that a 
much greater number of the preglacial-polar (the original 
arctic) species here had found an asylum, while the Be- 
ring Strait - way was the only one for the migration to and 
from the Pacific. 
The mere species-statistics and the few hints about other 
points of view hitherto given, are not sufficient however 
to get a clear understanding of the degree of affinity be- 
tween the different floras, it also must be examined how the 
families and genera are distributed outside the area here in 
question. 
In the following table (VIII) all families are entered (after 
En gier & Prantl) and their distribution in different seas in- 
dicated. Families not present in our area are set in ( ). 
For the others even the genera represented within this area 
are entered with their distribution (after De Toni, some du- 
bious statements however excluded, as also genera not repre- 
sented by identic species in the north Atlantic and Pacific). 
Monotypie genera are marked with 1., 1 ? indicates that some 
species more is referred with doubt to the same genus. Ge- 
nera not present in the Polar Sea, but wdth identic species in 
the northern parts as well of the Atlantic as of the Pacific are 
marked with*.
