name being the samara. Each key is long and flat with a seed shaped as a 

 long oval at the stem end and continuing into a flat leathery wing. 



WHITE ASH 



The white ash (Fraxinus americana) is native from Newfoundland and 

 Nova Scotia west to Minnesota and south to Florida and Texas. It reaches 

 its best development on rich moist soil where occasional specimens 120 feet 

 high and from five to six feet in diameter are found. It grows straight and 

 symmetrical, and forms a broad, rounded head which bears dense, graceful 

 masses of leaves. In the fall the leaves change color, and as they drop from 

 the tree expose a characteristic open head with erect rigid twigs with an 

 opposite arrangement. 



It is hard to understand why white ash has not been planted more ex- 

 tensively in California since it has many characteristics that recommend it 

 for a shade tree. It is a rapid grower, is hardy, and has few insect enemies. 

 For ornamental purposes, its open habit of branching affords a desirable con- 

 trast to bring out the beauties of other trees with more delicate branch systems, 

 and its light green leaves make an effective color effect against darker foliage. 

 It can be easily transplanted on account of its finely divided root system, 

 and should do well under good soil and moisture conditions. 



ARIZONA ASH 



Arizona ash (Fraxinus velutina) is a little known tree which is destined 

 to be widely planted in California along roads and highways because of its 

 ability to do well under adverse conditions. The tree grows naturally from 

 western Texas to the Owens Lake region in southern California, where it 

 inhabits the banks of the streams or borders of springs. In its native state 

 it is a small tree, from fifteen to thirty feet high, but under cultivation it 

 reaches a height of seventy-five feet. 



It has large, compound, willow-like leaves, gracefully drooping branches, 

 and large panicles of wing-like -fruit in the fall. It grows fast, and forms a 

 symmetrical, round top, which affords sufficient shade, although some sun- 

 light always finds a way through its irregular, wavy foliage. 



Arizona ash has the great merit of growing well in alkaline soil where 

 hardly any other tree will do, and is particularly well adapted to the arid
