Systemic analysis of ecology-and-floracoenotic characteristics of Achillea glaberrima Klokov localities on granitic exposure of the “Kamennye Mogily” natural reserve was conducted. Low species amount was fixed in the plant associations with this narrow located endemic. The endemic was entered in the World Red List (from 7,05% to 8,76% from 468 vascular plant species, growing in the natural reserve). Species structure of Achillea glaberrima localities differs from the natural reserve flora on systematic, ecological, ecology and flora coenotic, and geographical structure. High narrow locality of the endemic depends on its exactingness to the specificity edaphic conditions (granitic exposure without carbonates). Conditions of the given stenotopic species localities totally correspond to its ecological demands.
