分子证据和新增加的形态证据显示,银屏牡丹Paeonia suffruticosa ssp.yinpingmudan作为新亚种发表时所依据的两份标本实为两个实体,产自安徽巢湖的(潘开玉和谢中稳9701,模式)实为凤丹P.ostii的成员,而产自河南嵩县的(洪德元等H97010)实为一个新分类群.本文把P.suffruticosa ssp.yinpingmudan处理为P.ostii的异名,并依据河南的标本描述了一个新种--中原牡丹P.cathayana D.Y.Hong & K.Y. Pan.中原牡丹与风丹和矮牡丹P,jishanensis近缘,区别在于前者下部叶有11-15片小叶,花白色;后者小叶背面有毛,裂片多,萼片顶端圆钝,花白色.

Molecular data and new additional morphological data suggest that the two tree peonies,based on which Paeonia suffruticosa ssp.yinpingmudan was described as new,belong to two entities,the one from Anhui(K.Y.Pan and Z.W.Xie 9701,the type)being a member of P. Ostii,while the other from Song Xian,Henan Province(D.Y.Hong et al.H97010)being a new taxon.P. Suffruticosa ssp.yinpingmudan is here reduced as a synonym of P.ostii.and P cathayana D.Y.Hong & K.Y.Pan is described as new based on the specimen from Henan.The new species is closely related to P.ostii and P.jishanensis.but it differs from the former in having lower leaves with 9 leaflets and petals rose,while from the latter in having leaflets glabrous,ovate or ovate-lanceolate,less lobed,sepals all caudate at the apex and petals rose.
