摘要：
Paeonia decomposita Hand.-Mazz.subsp.rotundiloba D.Y.Hong is here raised to the specific rank,P.rotundiloba(D.Y.Hong) D.Y.Hong,based on its distinctiveness of four diagnostic characters:number of carpels;height of disk;number of leaflets of the lower leaves,and shape of the terminal leaflets;and unpublished molecular data.Paeonia rotundiloba differs distinctly from P.decomposita in having carpels mostly 3,less often 2 or 4,very rarely 5(vs.almost always 5,very occasionally 4 or 3),disk 8-15 mm high(vs.4-9.6 mm),leaflets mostly 19-39(vs.29-63) in number,and ratio of length to width of the terminal leaflets 1.09-1.93(vs.1.81-2.99).
