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 dmygdalus davidiami 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 Prank N. 
Meyer, Lan Tsai , Kansu, China, Nov. 3, 1914.
