SUGARBERRY (Celtis mississippiensis) A tree with habits sim- 

 ilar to hackberry. The leaves are large and smoother and the tree 

 reaches a larger size and greater age than the huckberry. Useful in 

 Central and Southwestern Texas. 



DESERT WILLOW (Cliilopsis Unearis)A native of the West Texas 

 draws. It stands drouths and much alkali. It is a small tree with 

 showy flowers and long cylindrical seed pods. The leaves are linear. 

 It is not regular in form, being similar to mesquite and willow in this 

 regard. A desirable tree under severely dry conditions. 



ORANGE (Citrus sp.) Various citrus fruit trees are used to ad- 

 vantage as shade trees along the coast below Corpus Christi. Abovo 

 Corpus Christi citrus trees are often seen but they do not reach the same 

 development that they attain further south and are frequently injured by 

 frost. They are medium sized to small trees with even rounded crown 

 and dark green glossy leaves, being more useful for lawns than for 

 street planting. They will not stand much frost. 



RUSSIAN OLIVE (Elaeagnus angustifolia) A handsome silvery- 

 leaved medium sized tree. It has a broad rounded head with a rather 

 irregular branching system similar to willow or mesquite. It stands 

 drouth and alkali, showing remarkably fast growth. It needs some 

 pruning to make a good shade tree for street purposes. 



BLUE GUM (Eucalyptus globulus^ Useful for planting along the 

 gulf coast. Freezes back at Port Arthur. A tree reaching great size 

 and age, of very rapid growth, causing roots to ruin walks, sewerage 

 systems and street pavements. Should be planted on wide avenues 

 where it can have some protection, as it will not endure a temperature 

 below 24 degrees Fahrenheit when young. It needs a humid climate 

 with good soil for proper development. With shallow soil or insufficient 

 soil moisture the growth of all eucalyptus trees is seriously retarded. 

 Other varieties may prove successful in Texas but have not been tried 

 out extensively as yet. RED GUM (E. rostrata) will stand a temper- 

 ature of 13 degrees after it becomes established and shows some promise 

 for the Southern coastal region. 



WHITE ASH (Fraxinus americana) This ash is native in East 

 Texas, growing in moist rich soils. The white ash is a large, well-formed 

 tree, fairly clean except for the seeds and a good shade tree, more at home 

 on lawns than on city streets, however. 



GREEN ASH (Fraxinus lanceolata)This is one of the best shade 

 trees which will grow in West Texas and the Panhandle. It is some- 

 what smaller and shorter lived than white ash and stands a dry climate 

 with alkali very well. It is fairly clean, does not break up and makes 

 a shapely tree. 



MAIDENHAIR TREE OR GINGKO (GingJco Uloba)This is a 

 Chinese tree introduced into the United States a number of years ago. 

 Although it has not been planted extensively in Texas it has shown 

 promise in the northeastern and central black land districts. It cannot 

 be recommended strongly as yet because sufficient data on its adaptability 

 is lacking.
