The system of concepts used when estimating the rarity of plants is analyzed and the basic categories of rarity are defined, namely: true, diffuse, peripheral and temporal. The insufficiency of scientific information on ecological and coenotic relationships of rare plants is demonstrated and the necessity of a complex assessment of population system of a rare plant species is substantiated. The importance and limitations of the information on rare plants contained in the Red Books and the Red Lists for phytosozological practice is discussed.
