M.; Paal’s research while affiliated with University of Tartu and other places

Infraspecific variation of Estonian Potentilla erecta (L. ) Rausch. was studied with different morphometrical methods. Both P. erecta sap. erecta and ssp. strictissima (Zimm. ) A. J. Richards were identified with ssp. strictissima prevailing; however, several specimens are morphologically of an intermediate type. Representatives of the two taxa haveno geographical or ecological preference in Estonia, and since it wasnot possible to statistically delimit them, we preferred to treat these taxa as varieties: P. erecta var. erecta and P. erecta var. strictissima (Zimm. ) Hegi.
