The article reports on the results of a floristic survey in the northern part of the urban district of Zaraysk, Moscow region, on the right bank of the Osetr River near the village of Argunovo. During the reconnaissance study, the composition of the steppe taxa that have survived to this day after the use of this territory in the 1960s as a quarry for the extraction of carbonate rocks was clarified. In an isolated area with limestone outcrops, populations of 6 rare and protected species were noted: Stipa pennata L., Gentiana cruciata L., Aster amellus L., Rosa villosa L., Pyrus communis L. and Campanula bononiensis L., included in the latest edition of "Red book of the Moscow region". The most valuable find is feather grass Stipa pennata, newly discovered in the urban district of Zaraysk, the nearest habitats of which are known in chernozem areas with the steppe Oka flora in the urban district of Serebryanye Prudy, Moscow Region. Rare populations of the ornamental cruciform gentian Gentiana cruciata and the well-preserved pear Pyrus communis, which may be of interest to the national economy, are of particular interest. For the first time, Aster amellus L., Lithospermum officinale L., Euphrasia brevipila Burnat & Gremli, and E. pectinata Ten were found in the urban district of Zaraisk.
