Ailanthus Tree of Heaven 



Few trees have the ability to withstand the smoke 

 and gases of towns and cities as well as the 

 Ailanthus. The cramped space often allotted to 

 curb trees is but a slight deterrent to this vigorous 

 species. The fertile plants are quite free from any 

 disagreeable odor at flowering time an objection 

 sometimes raised against the pollen-bearing or 

 staminate form. 



Ailanthus glandulosa. TREE OF HEAVEN. A rapid- 

 growing tree from China. Leaves odd -pinnate, with 

 13 to 25 leaflets, bright green. Flowers in large 

 panicles, succeeded by dense fruit-clusters which are 

 often very highly colored. Much used for street plant- 

 ing where smoke or dust affects other species. 



Albizzia The Mimosa Tree 



The hardiest member of this genus, described 

 below, will stand considerable cold, being hardy as 

 far north as Washington and Memphis. Very orna- 

 mental tree with feathery, graceful foliage and

 land. They are extremely valuable and ornamental 

 for waterside planting, and, in early spring, the 

 abundant staminate catkins are much admired. 

 The shrubby forms will be found in their respective 

 places under "Deciduous Shrubs." 



Alnus glutinosa. EUROPEAN, OR BLACK ALDER. A 

 vigorous and rapid-growing tree, native of Europe and 

 Asia. Leaves dull, dark green, the borders irregularly

 be effectively planted with these early-flowering 

 subjects. The shrubby species will be found in 

 their respective places under ' 'Deciduous Shrubs. ' '
