Lectotypes are designated here for the names Lilium pseudodahuricum M.Fedoss. & S.Fedoss., L. dauricum var. alpinum N.I.Kuznetsov and L. pensylvanicum f. praecox Vrishcz. The new combination L. pensylvanicum var. alpinum (N.I.Kuznetsov) J.Compton & Sytin is made and a key is provided to the varieties of L. pensylvanicum.
