The thematic area is located between Tâmburești and Sadova localities, in the southern part of Oltenia, south-east of Dolj County, in an area with sandy soil, also called "Sahara of Oltenia". The relief consists in plains and meadows covered by sand dunes. During the geobotanical research carried out in this area in the 2023-2024 period, several populations of Viola hymettia Boiss. & Heldr. (Viola, sect. Melanium) were identified. As a result of field studies, the presence of this rare species was found in the floristic structure of the plant communities specific to the sandy soils from south Oltenia. These populations were analyzed from a chorological, ecological and phytocenotic point of view in close correlation with the climatic changes of recent years and the degree of expansion of the surface of sandy soils in this part of Romania. Also, the species under study itself edify a community of plants Violaeto hymettiae-Cynodontetum Cîrţu 1973. The importance of this association lies in the fact that the participating species contribute to the stabilization of the sands and the enrichment of their humus content.
