ously and thrive best on a rich and heavy soil, and in situ-

There are several beautiful varieties of the Yew, ( Taxus 
baccata ,) cultivated in the nurseries ; the Irish Yew, (T.b. 
fastigiata ,) remarkable for its dark green foliage, and very 
handsome, upright growth, and the Yellow berried Yew, 
( T. b. fructo-flava ,) are the most ornamental. 
The North American Yew, (T. canadensis ,) is a low 
trailing shrub, scarcely rising above the height of four or 
six feet, though the branches extend to a considerable dis- 
tance. In foliage, berries, etc., it so strongly resembles the 
European plant, that many botanists consider it only a dwarf 
variety. The leaves are nevertheless shorter and narrower, 
and the male flowers always solitary. It is found in shady, 
rocky places, in the Highlands, and various other localities 
from Canada to Virginia.
