H. theinum - is the integral element of communities of a subalpine belt humid high mountains of the Central and Western Altai. The coenotical optimum H. theinum is in conditions toll-forbs communities of a subalpine belt. The comparative analysis ценопопуляций H. theinum testifies to their steady condition in natural communities the Ivanovsky and Prohodnoy ridges. Populations an optimum of H. theinum can achieve both in conditions coenotical an optimum, and in extreme conditions of the alpine meadows. Real organismic the optimum coincides with coenotical optimum. Here, in communities polydominant toll-forbs individuals H. theinum possess the greatest capacity and high seed efficiency.
