are the most widely spread ; for the most part restricted to the 

 northern hemisphere, they are not unrepresented south of the 

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

 as far south as Formosa 1 ,, Siam, the Malay region, the Philippines 2 , 

 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 

 Himalayas, and Japan. Tsuga is more especially a North American

 is characteristic of N.W. America and is recorded from Formosa. 

 Pseudolarix is a native of N.E. China and Formosa. Cedrus 3 

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

 layas. The distribution of the ARAUCARINEAE affords a 

 striking example of the contrast between the present and past 

 range of a family. Araucaria occurs in Brazil, Chile and Argen- 

 tina, in Australia, New Caledonia, New Guinea, the Pacific islands. 

 Agathis is confined to the Australian and Malay region, New Zea-
