CHMOPODIACEAE 



It occurs also in southern Idano, Utah and Levada but does not oc- 

 cur in Arizona or Lew Lexico. The low spreading habit of this bush 

 melees it a very -ood erosion control plant though it must be remem- 

 bered that none of the salt bushes with the possible exception of 

 A. s emibaccata , arc comparable to grasses as erosion control agents. 



The chief reason is that they never form continuous stands. This 

 plant is fair sheep browse. 



*Atr iplex corrugata is closely related to A, nuttallii. Its 

 range is much more limited than the latter, being confined to south- 

 ern Colorado and adjacent Utah, Arisen.', and Hew I'exico. The plants 

 are very low, woody at the base and spreading. As an erosion control 

 plant it is superior to A. nuttallii but does not supply as much 

 forage. Like A. nuttallii, it occupies rather heavy adobe soils, 



*Atr iplex r^arrettii, Garrett's 3a It Lush, is reported to have 

 been brought to Loo's l^crry, Arizona by a Ilormon missionary. This 

 has never been substantiated scientifically and probably is an er- 

 ror as it has been found also in several widely separated locali- 

 ties of southern Utah. At Lee's Ferry whore it grows in profusion 

 it is herbaceous or very slightly woody at the base and is low and 

 spreading. It is excellent stock food and worthy of very careful 

 experimental and observational work. 



*Atriplox polycarpa, Desert So.lt Lush, is extremely abundant 

 in the lower valleys of Arisona and adjacent California, Levada, 

 Utah and Hexico. It is perhaps oui most drought resistant salt bush, 

 and from the standpoint of forage, our most worthless one. Its use 

 in any revegetation program, can hardly be justified. 



*Atr iplex conf ertifolia, properly called Shad. Bush, is a very 

 low spiny bush with oval shiny silvery leaves. It forms dens'e 

 clumps but owing to the scattered nature of the stands does net con- 

 stitute a good erosion control plant. It constitutes a consider- 

 able nro portion of the browse for sheen and rroats in the Lavaio 

 region but is far inferior to canes cons as a forage plant. It 

 has about the same range as that species but is much more toler- 

 ant of alkali. 



"- Atr ip lex lentif omis, Giant Salt Lush, is our largest and 

 most striking salt bush. It is often ten feet high or more with 

 a main stem four or five inches in diameter at the base and a 

 spread of ton or fifteen feet. It frequently forms dense thickets 

 along washes ana irrigation ditches in our warmer regions. Its 

 natural distribution is southwestern and western Arizona, extreme 

 southern Utah, southern Levada, southern California and Ilcxico. It 

 constitutes fair forage and mckos a handsome ornamental as certain
