The authors have reduced the number of Paeonia species in the Caucasus to three (P. intermedia, P. tenuifolia, P. davurica) after extensive field and herbarium research showed that most morrphological differences could not be taken as a base for differentiation. The species P. davurica was divided into the five subspecies <i>mlokosewitschii, coriifolia, tomentosa, wittmanniana, macrophylla</i>.
