Vegetation of the Danish Provinces. 
As the proportion in Germany is as 1 to 22, and in Lapland 
as 1 to 55 ; so the proportion given for Denmark agrees very 
well with the progression, according to which these plants spread 
from the Pole to the temperate climate. 
The Cnicifera; attain their maximum in the temperate 
zone, but do not decrease in tlie same degree towards the Poles 
as towards the Equator, where they almost entirely disappear. 
Of these, 53 species are found in the Danish provinces. The 
proportion is therefore nearly as 1 to 22, which is considerably 
less than in Germany, where it is as 1 to 18, and a little larger 
than in Lapland, where it is as 1 to 24. 
The family of the Malvacetie, which has its maximum be- 
tween the Tropics, entirely disappears at the Pole ; so that we 
may expect that the number of them should not be great in this 
country ; which is the case, as there are only 6 species. The 
proportion here is as 1 to 199. 
An anomaly here appears, which is, that although there are 
two species less of this family than in Germany, where there are 
found eight, the proportion is greater than in that country, where 
it is as 1 to 235. This anomaly, however, almost disappears, if 
Ave omit Malva moschata of the Danish Flora, to which it hardly 
belongs, as it has probably escaped from gardens. 
The family of the Cary ophyllacece.^ with regard to the smaller 
plants reckoned in it, as the genera Stellar ia^ Arenaria, Sper- 
gula, &c. has its maximum towards the Poles ; these small plants 
■are either annual, or so small that they are easily covered and 
sheltered by the snow. The number of this family in Denmark 
amounts to 54 ; so that the proportion is as 1 to 21 ; in Lapland 
it is as 1 to 17, and in Germany as 1 to 21 ; so that the given pro- 
gression toAvards the Poles is confirmed by this. 
In Denmark are 59 species of Leguminosae.^ about g^^th of 
the Avhole sums. In Germany, the proportion is as 1 to 18 ; in 
Lapland as 1 to 35. 
'The Ame7itaccoc amount to 33, nearly g\th of the Phanero- 
gamous plants. In Germany, their proportion is as 1 to 39 ; 
; and. in Lapland as in 1 to 17.
