until recent years it has been the principal spring wheat grown in the so-called 
* Inland Empire.” 
Distribution—Grown as Bluestem in Arizona, California, Colorado, Idaho, 
Montana, New Mexico, Nevada, Oregon, Utah, and Washington. The distribu- 
tion is shown in Figure 21. 
Synonyms.—Australian, Bluestem, Chile, Palouse Bluestem, White Australian, 
White Bluestem, White Chile, White Elliott, and White Lammas. 
As indicated above, Australian, Bluestem, White Australian, and White 
Lammas are old names for the variety in Australia and the United States. 
Palouse Bluestem and White Bluestem are names which more recently came into 
use for this variety to distinguish it from other bluestem wheats in the United 
States. Chile and White Chile are names 
which came into use for the variety because 
cargoes of this wheat were received from 
time to time from Chile and in part were 
used for seed. White Elliott is a local 
name used for this wheat in Douglas 
County, Wash.

This popular variety was originated by Thomas Dart, of Nhill, Victoria, 
formerly of Lucindale, South Australia, and is a selection from a purple-straw | 
variety. It is one of the oldest varieties in general cultivation at the present | 
time.
