Potentilla cardotiana is similar to P. peduncularis in habit, but has radical leaf stipules with free auricles acute to acuminate at the apex, whereas the stipules of P. peduncularis have auricles connate from the base to the rounded apex. Many specimens of P. cardotiana collected in China were misidentified as P. peduncularis.
