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 em. 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.
