Western Szech'uan: near Sungpan Ting, alt. 2000-2900 m., 

 October 1910 (No. 4028). 



Prunus dehiscens is apparently very similar to P. mongolica Maximowicz, but 

 the latter differs according to the description of that species in its leaves, 1.1 cm. long 

 and 0.9 cm. broad, with four pairs of veins, in the scarcely compressed and sparingly 

 tomentose fruit, only 13 mm. long and 10 mm. broad, and the scarcely compressed 

 stone with firmly adhering flesh; of the dehiscence of the fruit Maximowicz says 

 nothing, nor does he describe the surface of the stone.

 of the fruit.
