SPECIES FOR STREET-PLANTING 1& 



The Norway maple bursts into a profuse bloom in the 

 latter part of April and early May, and is densely covered 

 with greenish-yellow flowers. They come out of the same 

 buds as the leaves, but develop much more rapidly, the leaves 

 being only half grown when the flowers begin to turn to seed. 

 In the same cluster may be found separate pistillate and stami- 

 nate flowers, and some flowers having both pistils and sta- 

 mens. The pistillate flowers mature into samaras, or keys, 

 with widely divergent wings. The fruit does not become 

 ripe until the fall, although it is fully grown in late spring. 

 The leaves have a marked resemblance to those of the sugar 

 maple, but they are darker and generally a little larger. 

 The leaf-stem exudes an acrid milky sap, which quickly 

 coagulates. This peculiarity of the tree makes it easily rec- 

 ognized. It has closely fissured bark, and grows a round, 

 compact head. The winter buds are much larger than 

 those of the sugar maple. 



The Norway maple is very hardy and easily trans- 

 planted. It is always rich in appearance, and looks attract- 

 ive on a street when other trees begin to show the waning 

 of summer. It puts forth its leaves earlier in the spring 

 and retains its verdure later in the season than our native 

 maples. Its leaves turn a clear yellow before falling. 



Sycamore Maple {Acer pseudo-platanus Linn.) . — This is 

 also a European tree, and it takes its name from the fact 

 that its leaves bear a resemblance to the sycamore. In its 

 habit of growth it follows the Norway maple, excepting that 

 the top is not so compact. It is not so hardy as the Norway 

 maple, however, nor is there anything distinctive about the 

 tree to make it preferable to the other hard maples. It is 

 also greatly subjected to the attacks of borers, and is not 

 so desirable for street use.
