 According to Batalin this is the only Almond which occurs in China. In fact 

 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. Petershourg, XXIX. 84; in Mel. Biol. XI. 670 [1883]).

» Prunus Taqueti Ldveille & Vaniot in Fedde, Rep. Sp. Nov. VII. 197 (1909) 

 proves to be a species of Rhamnus. 



2 Prunus communis Hudson (P. domestica Linnaeus) is reported from China as 

 wild and cultivated by Maximowicz, Diels, Forbes & Hemsley, Franchet and others, 

 but like Schneider I ^have seen so far no specimens from China, and must agree 

 with him, when he says (in Fedde Rep. Sp. Nov. 1. 50) that the occurrence of our 

 common Plum in China is very doubtful.
