neous, that is, out af 365 species 243 —67 per cent — belong 
to the autochtonous flora while 121 — 33 per cent — are anthro- 
pochorous. I. e. 33 per cent of the flora have been imported 
from other tracts with hay, packing, seeds intentionally brought 
in, and so on. The domiciliary rights of one species (UM ulge- 
dium. sibiricum) is dubious and, consequently, it is not inserted 
in either of the classes. 
From this it may be gathered that the part, by far the 
largest of the flora consists of primary elements. The figures, 
however, become more valuable when compared with others. 
SIMMONS (Flor. och veg. i Kir.) has compiled tables show- 
ing, that out of 459 species at Kiruna, a very young place as 
to eultivation, 267 are spontaneous and 192 anthropochorous: 
58 per cent belong to the primary flora and 42 per cent to the 
immigrated one. The vegetation of Kiruna for 10 years, or 
since the Ofoten railway was built, has been an object to a 
forced import of new species. The vegetation of Jukkasjärvi 
for nearly 300 years has got successive contributions of plants 
from other parts. Paths have crossed this old central point 
of Northern Lappland. But in Jukkasjärvi the inhabitants 
produced themselves the main part of the neccessaries of life 
and only a small part was imported from the south. At Ki- 
runa perhaps nothing of these things is PN everything 
is imported from other tracts. 
The result is that at Kiruna 42 per cent of the species, at 
Jukkasjärvi 33 per cent, are immigrants. 
Possibly a new time now will come for the vegetation of 
Jukkasjürvi: a road is built from Kiruna and the inhabitants 
of the first place probably will fetch their necessaries of life 
from Kiruna and their own produce will be lesser. 
If this is to take place, the anthropochorous element of 
the vegetation of Jukkasjärvi doubtless will be considerably 
enlarged,
