Dendrocalamus latiftorus, from the island of Formosa, "upright giant 

 bamboo." For low lands, and even where moisture might be excessive for other 

 trees, clumps of this giant bamboo will make magnificent avenues, in the same way 

 as they will make the most efficient wind breaks (if planted closer together). Does 

 well also on drier ground, as can be seen in Montecito, etc. For avenues should 

 be planted thirty to fifty feet apart. 



Deciduous Trees 



Acer macrophyllum, California. This has broader leaves than any other kind 

 of maples that are found scattered on the northern hemisphere, and it is certainly 

 one of the finest. In order to grow well and to retain its foliage until late it will 

 need plenty of moisture at the roots, as otherwise the leaves will begin to drop in 

 August or earlier. Same remark applies to other deciduous trees. This grows up

to eighty feet, and should be planted thirty to forty feet apart. 



Quercus lobata, California, "Valley Oak," "Roble" of the native Californians. 

 In deep soil and with plenty of moisture this makes a truly magnificent, widely 

 spreading tree, but could not be used under different conditions. May attain sixty 

 or eighty feet ; should be planted eighty to one hundred feet apart. 



Platanus racemosa, native "Plane" or "Sycamore." While the oldest trees are 

 often distorted in the most extraordinary ways, young trees can be easily trained 

 to any desired shape, and this kind has a beauty of its own unrivalled by other 

 deciduous trees. It may attain sixty feet or more, and should be set at least thirty 

 feet apart.
