STEEET AND HIGHWAY PLANTING. 



The tree itself resembles the other ashes, with large compound leaves, 

 inconspicuous blossoms, and large panicles of green samaras in the 

 fall. In Los Angeles the foliage was a good dark green, but in San 

 Bernardino, where the tree is largely planted, the foliage assumes a 

 gray-green color. The shade, while rather light, is entirely sufficient. 

 The tree is, of course, deciduous. 



Other species of ash are to be noted, especially farther north, where 

 the Oregon ash (Fraxinus oregona Nutt.) is often found. This forms 

 a good tree which is worthy of attention for the sake of variety. (Fraxi- 

 nus ornus is also found in rare cases? This does not become so large a 

 tree and is not so desirable for our purposes. 



THE GINKGO TREE. 



This tree (Ginkgo biloba) (Fig. 15) has been the subject of consid- 

 erable comment. It is a tree of unique appearance, having a very 

 characteristic style of branching and a wealth of fine foliage. The

foliage resembles a single one of the pinnae of the maiden hair fern on 

 a large scale, hence the name "Maiden Hair Tree" is sometimes used. 



As the species is direcious, pistillate flowers do not occur on every 

 tree, which is fortunate, as the mature fruits have an unpleasant odor 

 when crushed. Other than this there are no great objections to be 

 offered. The species is deciduous. 



Care should be taken to stake the plans well during the first years, 

 as the wood is somewhat brittle in those stages, but not noticeably so 

 afterwards. 



So far, all the specimens noted in southern California are rather
