STREET AND HIGHWAY PLANTING. 



Pittosporum rhombifolium is a species not common in California, but 

 is worthy of consideration. At best it is a medium-sized tree with fair- 

 sized smooth green leaves. Flowers are inconspicuous and are followed 

 by yellow berry-like capsules. This tree is more tree-like and erect in 

 habit than some of the other species. 



Pittosporum tenuifolium. This species is somewhat like P. euge- 

 noides, but is characterized by smaller leaves and very shining black 

 stems. It is of rather slow growth and needs special training to induce 

 a good tree-like form. It is in some ways more delicate and graceful 

 in appearance than P. eugenoides.

Pittosporum undulatum (Fig. 23). This form is usually found as a 

 plant in high hedges or windbreaks. It has rather larger leaves than 

 any of the preceding and they are of a thick texture and darker color. 

 The flowers are in terminal clusters, whitish, and are followed by showy 

 dull yellow berries. "Where it has developed into a tree it forms an 

 excellent broad spreading crown, but not a great height of trunk.
