ful. Unfortunately, the tree has a somewhat straggling habit unless 

 cared for with considerable pains in the youngest stages. This tree 

 has been used successfully in Pasadena. It is recommended for wide 

 streets, and of these only for such as have very wide parkings. 



Eucalyptus calophylla, R. Br. This tree came to notice in a particu- 

 larly fine specimen at Redlands. It is a tree of fair size with broad 

 leaves and terminal corymbs of showy white flowers which give the tree 

 a striking appearance at time of blossoming. The tree noted was in 

 full bloom in the early part of August, but this feature can not be 

 depended upon. This species does well in southern California, while 

 all of the specimens noted in the bay region were somewhat stunted. 



E. citriodora Hook. This species is commonly known as " lemon- 

 scented gum," and botanically is often grouped as a variety of 

 E. maculata. It is a tree with smooth, grayish-white bark and medium- 

 sized leaves which have a strong lemon-like odor. The flowers are white, 

 borne in axillary umbels. They are not particularly showy, but are 

 freely and markedly visited by the bees, which obtain considerable 

 nectar from them. This is a species needing at least roadside planting. 



E. cornuta Labill (Plate 2, No. 4). The Yate is a species forming a 

 small to medium-sized head. The largest specimen noted is at Berkeley, 

 on the University campus. It is a tree w r ith a spreading top, rather 

 broad leaves, and umbels of flowers peculiar for their beak-like caps 

 and long greenish-yellow stamens. These features often attract popu- 

 lar notice. The var. Lehmannii has even more striking flowers in this 

 regard, but at best it is but a large shrub. So far as was noted this 

 tree did not occur in street work, and so no recommendation can be 

 offered either for or against it. 



E. corynocalyx F. v. Mueller (Plate 3, No. 3). The sugar gum is 

 used rather freely in San Diego. It is found in most cases as a small 

 tree with broad foliage and rather slender tops. In most places the 

 practice of beheading has been carried on, so that in many cases there 

 was but a compact head of new shoots. This is hardly advantageous to 

 the beauty of the tree, but it has been necessary in order to keep the 

 tree within bounds. The tree is fairly popular and certainly has dis- 

 tinctive and attractive foliage. 



E. crebra, F. v. Mueller, is a form with small or medium-sized tree, 

 rather good sized leaves and many small flowers produced freely in short 

 panicles. This was not noted in the regular plantings and is not to be 

 recommended. 



E. erythronema Turcz. This is one of the most ornamental of the 

 smaller eucalypts. At present it is not very commonly found, but is 

 worthy of considerable notice. It is a small tree of not very rapid
