* It seems impossible at present to separate the following species by the shape 

 and pubescence of the leaves. In young plants of Prunus sibirica, P. Armeni- 

 aca and P. mume the leaves are much more densely pubescent than in older 

 plants in which the pubescence more or less disappears. The pedicels, the 

 cupula and the sepals, too, in the species were both glabrous or pubescent, and I 

 have not found it possible to determine the species of the section Armeniaca by the 

 leaves and flowers alone. Fruits and stones only furnish reliable characters.
