the true Almond, Prunus communis (Linnaeus) Fritsch=P. Amygdalus Stokes= 
Amygdalus communis Linnaeus) has not yet been found in China (see Maximowicz 
in Bull. Acad. Sci. St. Pétersbourg, XXIX. 84; in Mél. Biol. XI. 670 [1883]).

with him, when he says (in Fedde Rep. Sp. Nov. I. 50) that the occurrence of our 
common Plum in China is very doubtful. .
