The paper presents the results of geobotanical studies conducted on xerothermic grasslands located on the slopes of the Bug River valley near Kryłów, Kosmów and Stare Stulno. Patches of 4 associations and 2 communities of xerothermic grasslands of the class Festuco-Brometea and Trifolio-Geranietea sanguinei were found in this area. The share of xerothermic species was distinct in patches of semi-ruderal communities of Elymus hispidus and Elymus repens. Rare and protected plant species were present in the studied communities. Some fragments of the studied slopes appeared floristically valuable. Localities abundant in rare species, e.g., Nepeta pannonica (c.a. 200 specimens) and Euphorbia villosa (more than 50 clumps) were found. The most valuable objects should be legally protected as nature reserves or ecological grounds.
