Lagochilus proskorjakovii Ikram is a strict endemic in Nuratau ridge (north-western spurs of the mountain range of the Pamir-Alai). It grows as a part of Amygdalus bucharica and Perovskia scrophulariifolia formation, where the total projective cover of grass does not exceed 20%. In natural conditions growth, ontogeny of L. proskorjakovii is simple and complete. The duration of ontogenesis in the condition of Nuratau is no more than 22 - 23 years. Studied coenopopulations are normal, but are not complete. coenopopulation self-maintenance is carried out by the seed of renewal. The characteristic spectrum of coenopopulation centered, with a peak in the middle-generative individuals. In most cases, specific developmental spectrum of coenopopulation coincides with the characteristic ones. The absence or small proportion of the young fraction in surveyed of coenopopulation is related to the elimination of young fragile individuals. According to the classification of “delta-omega”, the most of coenopopulations are maturing which confirms the positive state of coenopopulation demography. Studied the ontogeny and structure of adult endemic Nuratau established that the species belongs to caudexum shrubs, perennial that forms the axis of the short multicipital caudex. Buds renewal is at a height of 2 - 3 cm above the substrate. Investigated coenopopulations L. proskorjakovii are successiveness conditions. In addition to the Artemisia juncea + Perovskia scrophulariifolia + Ferula ovina + Stipa hohenackeriana community 1st coenopopulation (CP) mature;the 2nd CP is mature which was a part of the Amygdalus bucharica + Perovskia scrophulariifolia + Prangos pobularia + Bromus scoparius community;3rd CP is maturing being a part of Lonicera nummulariifolia + Perovskia scrophulariifolia + Hypericum scabrum + Bromus danthoniae community and the 4th CP is mature which occurred in Amygdalus bucharica + Ferula varia + Acroptilon repens + Taeniath
