VEGETABLE PRODUCTIONS OF NORWAY. 263 
The Waite AupEeR (A. incana, Willd. Or,’ “ Older,” 
“‘ Hvidor,” &c.).—Grows as far north as Finmark. Its limit on 
the mountains is intermediate to that of birch and fir. In 
Finmark its altitude is about 1,200 feet above the sea. There 
are about six known varieties. 
Amelanchior ovalis, D.C.; A. sanguinea, D.C.; A. vulgaris, 
Monch, are only found in gardens near Christiania. 
American Arsor ViTz (Thuja occidentalis, L.).—Is found in 
gardens as far north as Throndhjem, where it stands the winter 
very well, Near Christiania there are trees 24 to 25 feet high. 
Ampelopsis hederacea, Mchx, or FivE-LEAvED Ivy, “ Vild 
Viin.”—Is common as an ornamental plant in the south of 
Norway, and grows as far north as Throndhjem. It stands the 
winter without protection. 
AsH (Fraxinus excelsior, L. “ Ask”)—Is common in lowlands 
as far north as lat. 624°. It does not attain a higher altitude 
than 1,500 feet in the south, nor more than 100 to 200 feet 
under lat. 62°, where also it will attain a growth of 80 feet in 
height. 
AsH-BrerBERY (Mahonia Aquifolium, Nutt).— Found in 
gardens in the south up to Christiania. It is not covered up 
during the winter. 
AsPEN (Populus tremula, L. ‘‘ Asp” or “‘ Osp”’).—Is very com- 
mon up tolat. 70°. At Aarnes, in Romsdal, lat. 63°, there is a tree 
60 feet high. Its limit on the mountains is about the same as that 
of the Scotch fir. The Norwegian peasant adopts a very practical 
way of getting rid of the troublesome shoots, which spring up 
even at long distances from the tree, and which are very difficult 
to eradicate from the soil. After the tree has been felled or 
sawn asunder, at about 4 to 5 feet above the ground, he strips all 
the bark off the stump. In about two years’ time the root loses 
all power of throwing out suckers. 
BastarD Inpigo (Amorpha fruticosa, L.).—Is cultivated near 
Christiania. The tops are generally frozen off in the winter. 
BasTarD Mountain Asu (Sorbus hybrida, L, “ Rognasal ”),— 
Is very common in lowlands in the south, and grows up to 
Throndhjem. On the eastern frontier it is not found higher than 
lat. 60°. In Hardanger it is very common to use stocks of this 
tree for grafting pears on. The fruit thus obtained is said to be 
better than by using common pear stocks.
