TREES OF NORTH AMERICA 



Taxus with six species, which can be distinguished only by their leaf characters and 

 habit, is widely distributed through the northern hemisphere, and is found in east- 

 ern North America where two species occur, in Pacific North America, Mexico, Europe, 

 northern Africa, western and southern Asia, China and Japan. Of the exotic species 

 the European, African, and Asiatic Taxus baccata, L., and its n\imerous varieties, is 

 often cultivated in the United States, especially in the more temperate parts of the 

 country, and is replaced with advantage by the hardier Taxus cuspidata, S. & Z., of 

 eastern Asia in the northern states, where the native shrubby Taxus Canadensis, 

 Marsh, with monoecious flowers is sometimes cultivated. 



Taxus, from rc^os, is the classical name of the Yew-tree.

Distribution. Banks of mountain streams, deep gorges, and damp ravines, grow- 

 ing usually under large coniferous trees; nowhere abundant, but widely distributed 



usually in single individuals or in small clumps from Queen Charlotte Islands and 

 the valley of the Skeena River, southward along the coast ranges of British Colum- 

 bia, Washington, and Oregon, where it attains its greatest size, along the coast ranges 

 of California as far south as the Bay of Monterey, and along the western slopes of
