the Danish Provinces. 
The Danish provinces (exclusive of Iceland, Faroe, and 
Greenland) contain, as far as is known, 1197 species of Monocoty- 
ledonous and Dicotyledonous ^ or perfect plants. 
Of these, 322 belong to the Monocotyledonous, a few more 
than Jth. 
Consequently the Dicotyledonous are 875, or |ths of the 
whole number ; the same proportion that Humboldt gives (in 
Prolegomena to nova gen. et species ) for the Temperate Zone. 
Of the Glumacea, amongst which are reckoned also the Cy- 
peroideoe^ Junceoe and Typhaceoe., there are found 216 species. 
The proportion these bear to all the Monocotyledones is as 
2 to 3, or with regard to the whole number of phasnerogamous 
plants nearly as 1 to 6 ; so that this answers very well to Hum- 
boldt’s proposition, according to which Germany has a propor- 
tion of these families to the other perfect plants as 1 to 7 ; Lap- 
land as 1 to 5. It shews also that the established principle, that 
the number of the Grasses in proportion to the other Mono- 
cotyledonous and Dicotyledonous plants increases towards the 
Poles, is right. 
Of tbe family of the Orchideac are found 26, about This 
does not quite agree with Humboldt’s representation, supposing 
that this family diminishes towards the Poles, as the proportion 
in Germany is ; in Lapland 
The decrease of the family of the Labiatos from the tempe- 
rate zone towards the Poles is very remarkable. The propor- 
tion it bears to the other is, in France as 1 to 24 ; in Germany 
as 1 to 26, and, in Finmark, as 1 to 71 ; so that we might ex- 
pect that the proportion in Denmark would be about 1 to SO ; 
but this is not the case, for that country possesses 48 species of 
this family, which is little less than ^\th of the whole number; 
so that the proportion is greater for Denmark than for Germany. 
Of the Denmark possesses 112 species, about ^\th 
of all its perfect vegetables. This agrees very well with Hum- 
boldt’s calculations, in as far as this family decreases in number 
from the warmer zone to the Pole, as the proportion in Ger- 
many is as 1 to 8, and in Lapland as 1 to IS, though according 
to Wahlenherg^ s Flora, the proportion is as 1 to 14. 
Of the family of the Umhelliferae^ which diminishes both to- 
wards the Equator and towards the Poles, there are in Denmark 
52 species, /^d of the whole.
