a point that it vail give any shade. This same style of growth necessitates 

 a large perking space. But more important than either of these objections is 

 the fact that the tree is a favorite host plent of the Black and other scales. 

 This fact would make it undesirable in all citrus growing districts as the 

 expense of spraying or fumigating shade trees is an expense which cannot be 

 termed as strictly necessary. 



The Parkinsonia. 



This tree (Parkineonia aculeata) is in reality a email tree or large shrub, 

 and so far as noted did not occur on the parkings. The leeves are very delicately 

 compounded with very email leaflets. The style of growth is very irregular; 

 flowers yellow, showy. It is of some interest as it is a native but is more 

 desirable as a shrub than as a tree. 



The Pines. 



The Pines are often found on the streets but the popular practice now is 

 to use them only for roadside plantings. Here they are often useful. 



Pinu s c ant? r i en si s . the Blue Pine, is a tree attaining a considerable size, 

 is of rapid growth and stands some drought. It is characterized by long droop- 

 ing needles of a glaucous color. Stump sprouts. 



The tree has slender branches and forms, at maturity, s. broad round-topped 

 head; though in its youth it has the pyramidal form characteristic of conifers. 



Pinu s. halepengis. the Jerusalem or Allepo Pine is a form with short 

 needles of a somewhat grayish color; of slender habit, with an open head; the 

 younger branches often assuming a peculiar twisted appearance. So far as could 

 be discovered, there were no very old specimens to show mature form. 



This is a species of no striking beauty but layo claim to usefulness from 

 its grert indifference to drought and considerable amounts of alkali. For this 

 reaeon it has a usefulness which will discount whatever it may lack in aesthetic 

 value, although it is not a poor looking specimen. 



Pinus radiate the Monterey Pine, is gradually being discarded in most parts
