NOTES ON A TOUR IN NORWAY AND COLLECTION 
OF PLANTS. 
BY W. P. MARSHALL AND C. PUMPHREY. 
(Concluded frontpage 6.) 
In Hooker’s standard account of the Arctic Flora (Tran¬ 
sactions, Linnean Society, Yol. XXIII., p. 251), the 
North of Norway and Lapland, a district of which the North 
Cape is the the central point, is described as containing by 
far the richest Arctic flora, amounting to three-fourths of the 
whole ; moreover, upwards of three-fifths of the species and 
almost all the genera of Arctic Asia and America are likewise 
Lapponian, or belonging to this Lapp district. 
The striking fact was brought out by Hooker that this 
Lapponian Flora is the most widely distributed flora over the 
earth ; it not only girdles the earth in the Arctic Circle, but 
dominates over every other flora in the North Temperate 
Zone of the Old World, and intrudes conspicuously into every 
other temperate flora, and has even migrated into southern 
latitudes. The greatest number of Arctic plants are located 
in Central Europe, no fewer than 530 out of 762 inhabiting 
the Alps and Central and Southern Europe. 
Hooker considers this fact can onlv be accounted for bv 
•' •/ 
Darwin’s hypothesis that the existing Lapponian Flora is of 
great antiquity ; that during the advent of the glacial period 
it was driven southward, and even across the tropics into the 
Southern Temperate Zone ; and that on the succeeding 
warmth of the present epoch, those species that survived 
ascended the mountains of the warmer zones, and also 
returned northward, accompanied by aborigines of the 
countries they had invaded during their southern migration ; 
their present distribution being accounted for by continuous 
slow changes of climate during and since the glacial period.
