STREET AND HIGHWAY PLANTING. 37 



Eucalyptus tmlliodora Cunn. This is another species attaining con- 

 siderable size. It is popularly known as the * * honey-scented gum. ' ' It 

 branches freely, bearing narrow lanceolate leaves, somewhat falcate, 

 of rather thick texture, about three or four inches long. 



The flowers are small, borne in crowded axillary umbels, and are not 

 showy. 



E. pi pc rit a Sm. This form is commonly called the "peppermint 

 stringy bark." It is a tall tree with rough persistent bark and large, 

 thick, scented leaves, resembling in shape those of the blue gum. The 

 flowers are rather small and many are borne in crowded axillary umbels. 

 As might be easily seen, they are not showy. 



E. polyanthema Schau (Plate 2, No. 3). This tree, commonly called 

 the red box tree, varies from a small to a large sized tree. Its bark is 

 rough and persistent. The foliage is rather characteristic, varying 

 from orbicular to ovate, and is of a distinctive gray-green color. The 

 flowers, though small, are produced in large terminal panicles, so that 

 they are rather showy. This tree has been recommended for street 

 work by some, but no plantations have been noted to date. 



E. pulverulenta Sims. This species is nearly always a small tree. 

 The foliage is quite characteristic, with sessile leaves, varying from 

 cordate to ovate in shape and showing a marked glaucous or even nearly 

 white appearance which is quite marked. The flowers are borne usually 

 in three-flowered umbels. They are not very showy and the chief value 

 of this species lies in the marked color of the foliage. 



E. Risdoni Hook. This form, sometimes called "drooping gum," 

 is a small or medium-sized tree with smooth bark and sessile, ovate 

 leaves of a very characteristic form and grayish color. The flowers 

 are small, white, and borne in axillary umbels. They are not par- 

 ticularly showy. The drooping habit of the branchlets and the char- 

 acteristic foliage make the tree a striking ornamental one. 



It has been recommended by some for street work, but so far as 

 noted has not been tried out. 



E. rostrata Schlect (Plate 3, No. 2). This form is quite near 

 E. tereticornis and resembles it closely in many ways, but having as 

 a rule somewhat narrower foliage. The characteristics often given for 

 the caps do not hold in many cases. The tree attains considerable size, 

 thrives best in fairly moist soil, tolerating flooding from time to time 

 and even a large per cent of salt in the soil. It is as hardy as the 

 blue gum. 



E. rudis Encll. This species is a medium sized tree, branching 

 freely. It has rough persistent bark and a marked drooping habit of 

 the branches, which gives it a very picturesque appearance. The
