36 STREET AND HIGHWAY PLANTING. 



growth, with medium-sized dark green leaves and axillary umbels of 

 brilliant crimson flowers. They are not as large as the flowers of 

 E. ficifolia, but are very freely produced and are quite as showy. The 

 tree has a good, erect, pyramidal habit. It was called to our attention 

 in San Diego, where an excellent specimen was shown. This tree, 

 perhaps, has a place on the streets. 



E. ficifolia, F. v. Mueller (Plate 3, No. 4). This is perhaps the 

 commonest of the showy forms of eucalyptus. The tree is one of 

 medium size, very similar in all general respects to E. calophylla, except 

 in certain characteristics of seeds, seed vessels and seedlings. The 

 flowers also are nearly always of a more brilliant color, ranging from 

 orange scarlet through crimson. This character does not always hold 

 on first inspection, as some of the forms of E. calophylla are deep red in 

 color. It is a small tree at best and has been used successfully in the 

 streets where the parking is of sufficient width to accommodate the 

 roots without danger of injury to sidewalk or curb. 



E. globulus Labill (Plate 3, No. 1). Blue gum is, of course, the 

 commonest eucalypt grown in California, and is too well known to need 

 description here. For it no place can be urged among the trees for the 

 city. Its beauty is undeniable, but its extreme size makes it unsafe at 

 times, causes breaking of curbs and sidewalks, necessitates extremely 

 large parking spaces at any rate, often interferes with water pipes and 

 in every way makes it inevitable that it should be given a place on a wide 

 boulevard in the country, where its great beauty and size may be 

 fully developed without interfering with the factors which go to make 

 city streets desirable in every way. 



E. goniocalyx, F. v. M. This is a medium-sized tree with large leaves 

 of a shape somewhat similar to that of the blue gum leaves. The bark 

 is rough on the trunk and somewhat deciduous on the upper limbs. 

 The flowers are borne in axillary umbels and are not showy. 



Since the leaves are rather pale in color and freely spotted it is 

 known in some parts of Australia as the "Victorian spotted gum." 



E. leucoxylon, F. v. M. This species is commonly found and is often 

 called the white ironbark. It is a fairly tall tree, branching fairly 

 well down the trunk, with light-colored bark which is deciduous. The 

 flowers occur in axillary umbels and are quite uniformly three i] 

 number. They are white in color and not particularly striking. 



This species is not one of marked individuality, but is a good tr< 

 and may find a place in some highway work. 



It is quite closely related to E. sideroxylon, which it resembles in most 

 ways, except in the bark and in several less conspicuous matters. The 

 var. rosea of the latter has pretty rose-pink flowers.
