Abstract
The results of the investigation of four cenopopulations of Leonurus glaucescens Bunge in the Altai region, Mountain Altai, Kazakhstan are presented. Ontogenesis of the main root caudex life form was studied. Th e main structural individual unit of an adult individual is a monocyclic monocarpic elongated shoot. Under the condition of moderate moistening L. glaucescens is polycarpic in the steppe meadows and steppe communities. Under the condition shallow groundwater L. glaucescens is oligocarpic. The Kazakhstan cenopopulation is distinguished from all studied cenopopulations. On the development of the aboveground part it’s individuals are inferior the individuals of other habitats. In the cenopopulations, a left-sided ontogenetic spectrum with an absolute maximum on the group of immature plants is noted, which indicates a successful seed renewal of the species
