Pacific or Calijornia Division. 13 



Pacific or California Dimsion. — This name has been very gen- 

 erality applied to the Pacific coast region of the United States. 

 It was first recognized by the botanist De Candolle in 1820. 

 Pickering, in 1830, named it the Californian Flora, but, knowing 

 little or nothing of the Sierra Nevada and believing the Rocky 

 Mountains to l)e the only mountain system of importance in 

 North America, extended its eastern boundary t6 that range. 

 In this he was followed by the botanist Hinds, in 1813; by the 

 conchologists, Amos Binney, in 1851, and Woodward, in 185(3. 

 Agassiz, in 1851, was first to fix its eijstern limit at the Sierra 

 Nevada and Cascade mountains, where it has been })ermitted to 

 rest. Its north and south Ixumdaries have undergone consid- 

 erable fluctuations. 



The extent to which the Pacific or Californian region has been 

 recognized will appear from the following table : '*■
