112 Forest Club Annual 



White Ash (Fraxinus americana Linn.). 

 This tree possesses many of the desirable characteristics 

 for city planting. The leaves growing in irregular masses 

 are of light color and never so dense as to exclude the light. 

 Its crown, either rounded or pyramidal, is well adapted to use 

 on the streets, but the late appearance of the leaves in spring 

 and the dropping of the leaves early in autumn are objections 

 to its use. It is adapted to wet and compact soils, but will 

 thrive best on dryer sites. 



Hackberry (Celtis occidentals Linn.). 

 This species resembles the elm in general appearance 

 but has a more compact and spreading crown and a denser 

 foliage. It is tolerant of many soil conditions, being found 

 along streams and also on drier sites, and is comparatively 

 free from diseases. The peculiar warty appearance of the 

 bark is a distinguishing feature. 



Ginkgo (Ginkgo l)ilol)a Linn.). 



This tree was imported from China. It is hardy and 

 gives promise of becoming a valuable shade tree. It is en- 

 tirely free from insect attacks and makes a desirable species 

 to plant as single specimens on lawns or near houses. The 

 city of Washington has used the tree quite extensively for 

 street planting. The fern-like character of the leaf is pecu- 

 liar and has led to the name of Maiden-hair Tree. 



Hardy Catalpa (Catalpa speciosa Linn.). 

 The large heart-shaped leaves and pyramid-shaped clus- 

 ters of flowers make the catalpa in spring-time one of our 

 most beautiful ornamental trees. The short trunk with long 

 straggling branches which form an irregular crown is not at 

 all attractive except during the period of flowering. The 

 pods hang on the tree during the winter and as they fall to 

 the ground, they break open, allowing their seeds to be tossed 

 about by the winds to litter the street. It is not satisfactory 

 for street planting. 



Alianthus* (Alianthus glandulosa Dest.). 

 This tree has many characteristics which render it unfit 

 for street planting. The unpleasant odor given off at blos- 



*Ailanthus is not hardy in Nebraska.
