ABSTRACT: Lepidium subcordatum Botsch. et Vved. (Brassicaceae) is a rare endemic
species of relict mountains of the Kyzylkum desert. The plant is listed in the “Red
Data Book of Uzbekistan”. It grows on stony and rocky slopes of relict
mountains. The ontogenetic structure of five coenotypical populations of this
taxa growing in the Kuldzhuktau and Auminzatau mountains had been revealed. The
ontogenesis duration is more than 20 years in natural habitats. All
investigated coenopopulations can be assessed as normal and incomplete. The
typical spectrum of coenopopulations is centralized with a peak in the
middle-generative individuals. The ontogenetic spectrum of the most studied
coenopopulations coincides with the characteristic ontogenetic structure that
indicates a favorable environmental condition in region for self-maintenance of L. subcordatum coenopopulations.
