Analysis of morphological variability in Malva neglecta in six coenopopulations in different phytocenoses made it possible to identify the breadth of variability and similarities between the compared coenopopulations. The studied characteristics of the studied species can be arranged according to the increasing level of variability according to the following scale: mass of an individual, length of vegetative shoots, length and width of leaves, mass of generative individuals, number of flowers on a shoot. The coefficients of variation for each trait in coenopopulations are stable. The vitality of coenopopulations within the studied region varied from 0.37 to 0.74. The cenopopulation of the studied species, growing near the Sangzor River, is characterized by lower vitality. According to the IQ parameter, most cenopopulations were in equilibrium. A depressed state was noted in cenopopulations 2 and 6. The average density of Malva neglecta is 0.9-1.45 pcs/m2; the greater the density and number of individuals, the higher the vitality index.
