Potanin's Wild Peach of the Kansu Province of China 

 (Prunus persica potanini) . 



This is called the "Mao tao" or hairy peach and be- 

 longs to the same general type as Amygdalus davidiana but 

 may withstand even greater heat and prove of value as a 

 stock in the arid west (S.P.I. .Nos. 39899, 40007, 40008, 

 40009). Natural size photograph No. 13091 by Frank N. 

 Meyer, Lan Tsai , Kansu, China, Nov. 3, 1914.
