As the specimens cited above are in leaf only, their identification remains 

 open to doubt. Maximowicz (in Bull. Acad. Sci. St. Petersb. xxix. 84; 

 in Mel. Biol. xi. 672 [1883]) mentions a double-flowered form sent by 

 Bretschneider from Peking where it is cultivated.

A supposed hybrid between Prunus Armeniaca and P. salicina is men- 

 tioned under the name "Plumcot" by F. N. Meyer (in U. S. Dept. Agr. 

 Bur. PI. Indust. Bull. cciv. 22 [Agric. Explor. Orch. China] [1911]). He 

 states that it is called "Lishing" by the Chinese and that about three 

 varieties of it are grown in the Shantung province.
