A Drought-Resistant Asiatic Plum 'Prunus sp.; S. P. I. No. 55901; 



A hardy wild plum which is drought and heat resistant deserves trial as a stock for regions 

 in the United States where dry hot summers combine with cold winters to make the grow- 

 ing of stone fruits very difBcult. This species was discovered in limestone soO on the Likiang 

 Snow Range. Yunnan, China, at an altitude of 10,500 feet, where it grows as a spreading 

 tree 20 to 25 feet high. It bears a large number of round lemon-yellow fruits an inch in di- 

 ameter. Its native region is subject at times to intense heat and drought, and snow falls 

 in the winter. (Photographed by J. F. Rock, September 1, 1922; P30289FS)
