The structure of stable taxonomic quantitative diagnostic features in Oenothera populations has been studied. The investigation of the system of correlations of six generative features in 36 different geographic populations of the genus Oenothera allows making a conclusion as for the considerable isolation of Oe.issleri species and some distinctions of Oe.glazioviana and Oe.rubricaulis from the rest of the species investigated. Divergence of the morphological traits obviously can be explained by the microevolutionary processes within these populations as well as by its adaptation to local environments. At the same time a distinct increase or decrease of the strength of the link under extreme anthropogenous conditions of existence have not been observed in species of the genus Oenothera, being observed in some other species. Simultaneously the relationships of traits variability and environment being of more complex complicated character. The populations of oenothera’s species which are geographically distant are very often closer by their structure of correlation than those which grow near, but under different ecological conditions.
