 northern hemisphere, they are not unrepresented south of the 

 equator. Pinus reaches the tree-hmit in the north and extends 

 as far south as Formosa i, Siam, the Malay region, the Phihppines^ 

 ,S. Africa, and the West Indies. Picea has a similar distribution 

 in the north and reaches to the temperate regions of the southern 

 hemisphere. Abies ranges from Europe and Algeria to Siberia, 

 the Himalayas, Japan, and Formosa. Larix flourishes in northern 

 Europe and Siberia, Canada and the northern United States, the

 occurs in Algeria, Morocco, Syria, Cyprus, and the western Hima-
