Cere is occidentalism "..'hen our ".."estern P.edbud is better known 

 doubtless it will be more widely used as an ornamental* It closely 

 resembles the eastern redbud which lends such beauty to the hard- 

 woods regions in the east in early spring. V.'ith us the redbud is 

 a large shrub or small tree found only in rather secluded places 

 in canyons ant. rock crevices in southern Utah, Nevada, California 

 and Ariz or a • It ha s boon located in the Grand Canyon where it is 

 abundant} in the Superstition fountains and in the Caboquivari 

 Mountains in Arizona* No c.vper imental work haci been carried on 

 with this species to determine its adaptability for planting. It 

 should be remembered that it ; : a a legume that is drought resistant 

 and that it is a beautiful shrub or tree* 



*01edit sia triacanthos, the Honey Locust, has been planted in 

 many sections of -'die United States and elsewhere. Some years 

 back contests were conducted in the schools and elsewhere to obtain 

 the largest seed pods. Sore experiments were conducted to determine 

 the sugar' content of the pods. In every way the tree shows remark- 

 able possibilities, it is much hardier than black locust, not being 

 subject to borer attacks but docs not produce such durable wood. 

 The pods constitute excellent food, for- stock and may be utilized 

 for human consumption. If methods can be devisee to grind the pods 

 and seeds to add to their value for food for stock, the use of this 

 species should he accelerated. As a tree for range planting in 

 Region G its use has bee;;, at least for the present abandoned because 

 of severe damage to the young trees by rabbits. 



Parkinso nia acvloata is probably the rest important of our 

 Palovcrd.es from the standpoint of use. it is a handsome ornamental 

 which has gained a place 5xi street planting programs in our 7/armer t-» 

 sections. Under irrigation it is rapid growing. It lias been intro- 

 duced to South Africa and has escaped cultivation in many places. 

 It can hardly be considered, an erosion control plant as it is not 

 sufficiently abundant. Its boons have been used in the past for 

 human food and the- are greedily eaten by animals when they can he

Ccrcid ium torrovanum, the large Paloverde, is one of the most 

 common sights on the desert. Doubtless its roots play an important, 

 part in holding the soil along dry washes. Since our work thus far 

 has been confined to regions in which none of the palovcrdcs will 

 grow, this tree has not gained a place in our planting or nursery 

 programs. It, however, plays a part in the economy of the desert. 

 The. beans are browsed by stock and were formerly oaten by Indians.
