VARIATION OF POTENTILLA-ERECTA (ROSACEAE) IN ESTONIA

Infraspecific variation of Estonian Potentilla erecta (L.) Rausch. was studied with different morphometrical methods. Both P. erecta sap. er ecta and ssp. strictissima (Zimm.) A. J. Richards were identified with ssp. strictissima prevailing; however, several specimens are morpholo gically of an intermediate type. Representatives of the two taxa have no geographical or ecological preference in Estonia, and since it was not possible to statistically delimit them, we preferred to treat thes e taxa as varieties: P. erecta var. erecta and P. erecta var. strictis sima (Zimm.) Hegi.
