Caucasus to Japan, and widely spread in North America. 



We have seen no Chinese specimens that we could refer to 

 this species (if we retain P. chinensis as distinct), which in 

 foliage is so near some of the forms of P. chinensis as to be hardly 

 distinguishable. Indeed we are not satisfied that the two are 

 specifically separable ; though the latter usually has much smaller 

 and more numerous flowers than the former. Franchet and 

 Savatier (op. sup. cit.) indicate differentia] characters in the 

 foliage and sepals, admitting at the same time that they are of 

 little importance.

A variable species, widely spread in temperate Asia and North 

 America. We have some doubt whether Boss and Hancock's 

 specimens referred here may not rather be a reduced state of 

 P. chinensis.
