AN ACACIA TREE IN BLOOM 



There are more than a hundred 

 species of acacias introduced into Cali- 

 fornia from the Southern Hemisphere, 

 and many of them have become very 

 popular. Their value as ornamental 

 trees is well suggested by this photo- 

 graph. Unfortunately, they are not as 

 hardy as could be desired, although 

 they thrive almost everywhere in 

 California. One of the African spe- 

 cies of acacia yields the gum arable of 

 commerce.
