title: Intra- and interspecific variability of &lt;i&gt;Mentha arvensis&lt;/i&gt; L. and &lt;i&gt;M. Canadensis&lt;/i&gt; L.
abstract: The identification of plants of the genus Mentha is often difficult due to significant intraspecific polymorphism, intense interspecific hybridization, and ploidy changes. An attempt was made to apply an integrated approach to the study of different parameters of two species: Mentha arvensis L. and M. canadensis L. Eight geographically dispersed populations of Mentha in different regions (European Russia, Khakassia and Far East, Western Ukraine, and Indochina) were studied. Diagnostic morphologi
