19912. Sesbania macrocarpa. 



From Yuma, Ariz. Received through Mr. E. L. Crane, March 2, 1907. 



" This plant grows to a height of 15 feet or more and covers hundreds, 

 perhaps thousands, of acres of the rich alluvial soil along the banks of the 

 Colorado River, south of Yuma. It is perhaps one of the largest annual 

 leguminous plants in America and is remarkable as covering completely such 

 large areas of land. The roots are leaded with nodules and it is probable that 

 this plant has for hundreds of years added materially to the fertility of the 

 delta region of the Colorado River. The attention of Prof. R. H. Forbes, of 

 the Arizona Agricultural Experiment Station, at Tucson, Ariz., and the atten- 

 tion of the writer were attracted at about the same time to the possibility of 

 this plant being a valuable species for increasing the nitrogen content of soils 

 in the Southwest. Seeds were collected for the purpose of making this test, 

 and the preliminary trials have shown it to have considerable value for this 

 purpose. It should be sown in late spring, as it requires a great deal of 

 warmth for germination." (Fairchild.) (See Bulletin 1903, Arizona Agricul- 

 tural Experiment Station.)
