44 A VOYAGE TO SPITZBEBGEN. 
almost without exception, natives of the Scandinavian 
peninsula. (2.) There was in the Greenland flora 
scarcely any admixture of American types, which, 
nevertheless, were found on the opposite coast of 
Labrador and the Polar Islands. (3.) A considerable 
proportion of the common Greenland plants were 
nowhere found in Labrador and the Polar Islands; 
nor, indeed, elsewhere in the New World. (4.) The 
parts of Greenland south of the Arctic circle, though 
warmer than those north of it, and presenting a coast 
400 miles long, contained scarcely any plants not 
found to the north of that circle. (5.) A considerable 
number of Scandinavian plants, which are not natives 
of Greenland, are nevertheless natives of Labrador and 
the Polar Islands. (6.) Certain Greenland and Scan¬ 
dinavian plants, which are nowhere found in the 
Polar plains, Labrador, or Canada, reappear at con¬ 
siderable elevations on the White, and the Alleghany, 
and other mountains of the United States. No other 
flora known to naturalists presents such a remarkable 
combination of peculiar features as this, and the only 
solution hitherto offered is not yet fully accepted. It 
is that the Scandinavian flora (which had been shown 
by himself to be one of the oldest on the globe,) did, 
during the warm period preceding the glacial—a 
period warmer than the present— extend in force over
