Among the wild woody Paeonia species (Sect. Moutan DC) only two species, this new one and P. suffruticosa subsp. spontanea, have leaves strictly biternate, with nine leaflets. The new species differs form P. suffruticosa subsp. spontanea in having leaflets ovate or ovate-rounded, mostly entire, with only the terminal ones shallowly lobed or toothed, and purple-red on the upper surface. Only one population has so far been found on the cliff in the Shennongjia Mountains at an altitude of 1650—2010 m. Certainly it is an endangered species.
