The fruit of this wild plum is of no consequence 

 as found in the Desert of Gobi, but the shrub is 

 evidently exceedingly hardy. The seeds were 

 collected at the eastern extremity of the Altai 

 Mountains, along drainage courses, at an altitude 

 of about 4,000 feet. (Berley.) 



Introduced for trial as a hardy stock for stone 

 fruits.
