From a consideration of this table, it is evident that the flora of these 
southern mountains coincides with that of the general Sierfa Nevada. 
Southern Extension of Californian Plants. A number of trees of shrubs 
of California proper find their southern limital extension in the peninsula of 
Baja California. Such are: Pinus Feffreyi, Pinus Lambertiana, Libocedrus de- 
currens, Rhamnus californica, Funiperus californica, Abies concolor, Sambucus 
glauca and Symphoricarpus mollis‘). This peninsula in conclusion contributed 
Pinus Parryana and Washingtonia filifera to southern California. 
he Coast ran ge is the general name for the great mountain system 
which stretches along the Pacific coast from Puget Sound to southern Cali- 
fornia. It is not a continuous range, but a broken mass of parallel, ridges 
from forty to seventy miles wide, with many other chains transverse to the 
general trend of the range. Streams cut through the mountains here and 
there and through their valleys flow fogs to modify the local climates. In the 
Coast range, there is no warm belt, but isolated warm spots, which depend 
on altitude, prevailing wind, fog and exposure. The rainfall is even more 
<apricious than the temperature. The eastern slopes are dry and the western 
in general wet. Under such conditions, the flora of the Coast range cannot 
be other than interesting, for plants are much localized and frequentiy found 
there out of their usual range. The full explanation of these peculiarities will 
© given in a short space.
