teriorates, being especially susceptible to wind breakage and subsequent 

 rot. It is a tree which should be used only where quick results are 

 desired and then more permanent trees, should be used also, to succeed 

 it after a few years. 



UMBRELLA CHINABERRY, TEXAS UMBRELLA (Melia azeda- 

 rack umlraculifera} This is an horticultural variety of the preceding 

 species. It develops a flat umbrella-like crown, very dense and regular. 

 It is a very handsome tree and a useful one for formal effects. How- 

 ever, it has most of the defects that the chinaberry has ; brittle branches, 

 much litter, and short period of attractiveness. 



WHITE MULBERRY (Morus alba) Introduced from Europe. It 

 does well on dry lands but prefers a moist soil. It is a small tree with 

 a round head, fairly well adapted for street planting, but the berries are 

 objectionable on sidewalks. This is the silk-worm tree of Europe. 



RED MULBERRY (Morus rubra) A native tree somewhat larger 

 than the above named species. The red mulberry is hardy and makes a 

 good shade tree in dry regions. The fruiit attracts flies and is a dis- 

 agreeable feature. 



RUSSIAN MULBERRY (Morus alba tartarica) This tree, a native 

 of Asia, is hardier than any of the other mulberries, and although it is a 

 small bushy tree, still it has some Advantages for the treeless portion of 

 the state. At elevations, above 1800 feet it is apt to be killed back by 

 late frost. It is not long-lived but is a fairly rapid grower and not a 

 heavy bearer, which is an advantage for shade purposes. 



OLEANDER (Nerium oleander) A large shrub or small tree with 

 a wealth of flowers. It thrives along the coast where the winters are 

 not too severe and does well under severe city conditions. 



SOUR GUM, TUPELO (Nyssa sylvatica)A. tall tree with slender 

 droo'ping branches. The foliage is dark green and lustrous, assuming 

 attractive shades in the fall. It is a slow growing tree suited to wet 

 situations. The fleshy fruits are a disadvantage. The COTTON GUM 

 (Nyssa aquatica) is very similar to the sour gum. 



HUISACHE (Acacia farnesiana) A small thorny tree with fragrant 

 yellow flowers. It makes a fair street tree in Southwestern Texas but 

 is a slow grower and has a somewhat irregular crown. 



SYCAMORE (Platanus occidentalis) One of the largest and best 

 shade trees over most of the State. It is a fast grower, develops a large 

 round head of stout branches, and although susceptible to leaf diseases, 

 yet these may be easily controlled by spraying. It is not attacked by 

 insects nor affected by adverse city conditions. Furthermore, although 

 best adapted to wet situations it will thrive with very little moisture 

 and care. 



ORIENTAL PLANE TREE (Platanus orientalis)A European 

 tree more enduring of city conditions, and possessing a more compact 

 crown than sycamore, but otherwise similar to it. It is a better tree 

 than sycamore for city purposes, not being affected by leaf blight.
