Veiy closely allied to, if not identical with, the Japanese species Prunus 

 Yamasakura (a wild mountain-cherry). I do not think our plant is ever 

 distinct specificially from the named species. The only difference between them 

 is that the stipules of our plant are much narrower and serration of the leaves 

 is a little looser, than those and that of the Japanese. It may constitute a 

 subspecies or a variety of the latter. I am quite unwilling to treat our plant 

 as a species distinct from the Japanese cherry; yet, the hitter is so very con- 

 fusing as to its proper name that it is at present as equally subject to altera- 

 tion to place the Formosan plant under one name as under others.
