localities where a light shade is desired. Its beauty of outline is well shown 

 in MacWherter s picture of a group of birches entitled &quot;The Three Graces.&quot; 



BLADDER-NUT TREE 



The bladder-nut tree (Koelreuteria paniculata) which was named after 

 J. G. Koelreuter, professor of natural history at Karlsruhe, is native to China 

 and Japan. It is a medium sized tree with a picturesque branch habit and a 

 heavy foliage of finely cut, dark-green, compound leaves. Small yellow flowers 

 are borne in large terminal panicles followed by conspicuous bladder-like pods. 

 It is sometimes called the &quot;varnish tree&quot; because of its glossy foliage. 



This tree flourishes in the smoke-infested towns of England such as in 

 the outskirt districts of Liverpoool and Manchester, and has clone well under 

 adverse conditions of soil and moisture in California. It is said to endure alkali 

 better than most trees which entitles it to consideration in some parts of the 

 state. 



BOTTLE-BRUSHES 



The bottle-brushes are mostly Australian trees and shrubs which are 

 widely planted in California because of their beauty and hardiness in with 

 standing drought and abuse. The bottle-brushes embrace several genera but 

 the name is especially applicable to the genus Callistemon, a word derived 

 from two Greek words, kallos (beauty) and stemon (stamen). In most of 

 the species the stamens which protrude from the blossoms are of a beautiful 

 scarlet or crimson color. The flower clusters resemble bottle-brushes in shape 

 which gives the common name. 



Callistemon lanceolatus is one of the most attractive of the bottle-brushes. 

 It has an erect growth and reaches a height of about twelve feet. In Australia 

 it is thirty feet tall and eighteen inches in diameter. The wood, which is 

 heavy and hard, is used there for mallets. It has very short and broad leaves 

 and bright red flowers. 



The genus Melaleuca has not as showy flower clusters as Callistemon, but 

 the various species are more symmetrical in outline. All species are hardy in 

 nearly every locality in California except in mountainous districts. A lux 

 uriant development is secured in some parts of the state under a combination 

 of warm summers and moist soil.
