48 ARKIV FOR BOTANIK. BAND 10. w:o 9. 
Summary. 
The old Lappish-Finnish village of Jukkasjärvi in the 
parish of the same name is situated in the northernmost part 
of Sweden in Torne Lappmark, in lat. 67° 50' N., at a distance 
of 17 kilometres from the great mining town of Kiruna. 
The village is nearly 300 years old, and thus the plants 
brought in through the influence of man have had a consider- 
able time to intrude upon the native flora of these parts. 
The struggle must have been fluctuating; man has tilled 
the soil, hay has been imported, seeds of new plants have 
germinated and formed vegetations and occasionally the old 
and hardy flora has again supplanted the encroachers. 
The present state of things in this strife of species at this 
place of old cultivation — one of the most ancient in all Lapp- 
land — is to some extent shown by my annotations, put down 
in 1909 and 1910. 
The district which I have examined covers the aforesaid 
village together with the shores of the lake of the same name 
and the slopes of the surrounding hills. The main part of it 
lies in the pine-region, though some points rise into the birch- 
region. 
Consequently the main part of the flora consists of species 
belonging to the coniferous forests, blended, however, in a 
considerable degree with elements belonging to the subalpine 
birchforest and lastly of a few principally alpine plants. Further 
there is a rather large contingent of southern immigrants, 
which owe their appearance here to their having been introduced 
in the fields of the old Finnish villages from where they have 
gradually spread into the forest-and moorland along roads 
and paths. 
On examining the Jukkasjarvi flora, systematically arrang- 
ed in these pages, the main part of it will appear to be sponta-
