In collections P. serrulata is very often confused with P. Sargent? Rehder and less 
often with P. pseudocerasus Lindley or with P. Herincquiana Lavallée. It is said 
to have been introduced in 1822 from China according to Lindley, but I have seen 
no specimens from China. Chinese localities for it are sometimes given, but always 
with the quotation of synonyms which show a confusion between P. pseudocerasus 
Lindley and P. serrulata Lindley, so that these indications can not be safely used.
