The taxonomic composition of monocotyledonous plants in the region, consisting of 27 species from 5 families and 20 genus, was determined. In addition, a list of adventitious species distributed in the city flora was formed, and according to the results of the preliminary study, 20 species of alien plants were recorded. Keywords: Fergana valley, urbanoflora, adventiv, monocotyledonous, flora. Introduction: Urbanized areas in the world occupy only 5% of the total land area, and are home to about 3 billion people. This is due to the increasing scale of urbanization, which is leading to a great deal of attention being paid to the study of urban vegetation cover. The study of urban flora is one of the priority areas of modern floristics and phytogeography, and its scientific importance is steadily increasing due to the intensification of anthropogenic pressure both in time and space. Urban plant cover communities are in different ways related to human influence and The American Journal of Agriculture and Biomedical 6 https://www.theamericanjournals.com/index.php/tajabe Engineering The American Journal of Agriculture and Biomedical Engineering therefore are different for each structural unit of the cities; city (Umedov and Esanov, 2024).
