CHIHLI：北京？（前马克西莫维奇）。高加索至日本，并广泛传播于北美。我们还没有看到任何中国标本可以指称这个物种（如果我保留 P. chinensis 为独特的话），它的叶子与 P. chinensis 的某些形式非常接近，以至于很难区分。事实上，我们并不满足于这两者是明确可分离的；尽管后者通常比前者的花朵小得多，数量也多。 Frnnchet 和 Saratier（前引）指出了叶子和萼片的不同特征，同时承认它们并不重要。
CHIHLI: Peking?(ex Maximowicz). Caucasus to Japan, and widely spread in North America. We have seen no Chinese specimens that we could refer to this species (if me 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. Frnnchet and Saratier (op. sup. cit.) indicate differential characters in the foliage and sepals, admitting at the same time that they are of little importance.
