The current state of Iris magnifica (Vved.)F.O. Khass.has been studied for the first time in the northeastern part of Aknausai of Kashkadarya region in Uzbekistan.A list of 74 plant species with the participation of this species is given.The described grass-wormwood-shrub community ( Lonicera nummulariifolia, Amygdalus spinosissima, Cotoneaster multiflora, Artemisia tenuisecta, Hordeum bulbosum, Hypericum perforatum, Prangos pabularia, Rheum maximowiczii) with the participation of Iris magnifica is very rich in species composition, the total number of species is 74, of which 4 are trees, 9 shrubs, 3 semi-shrubs, 43 perennials, 15 annuals.It should be noted that the predominance of perennial plants is a characteristic feature of the mountain systems of Central Asia.The edifiers of the studied community are: Lonicera nummulariifolia, Amygdalus spinosissima, Cotoneaster multiflora, Ceracus erythrocarpa and Spiraea hypericifolia, which are found with an abundance of sp1.In the first tier, trees -Malus sieversii, Pyrus regelii and Acer semenovii with a height of 1.5-3 m, as well as shrubs -Crataegus turkestanica and C. pontica met singly with a height of 1.5-2 m.Among the semi-shrubs, wormwood species -Artemisia tenuisecta (cop1) and A. ferganensis (sp2-sp3) with a height of 50-60 cm prevail.The object of the Iris magnifica study met with an abundance of sp2.Since there was an abundant occurrence of young individuals in this territory, Iris magnifica can be recommended for moving from the 2nd to the 3rd status in the Red Book of the Republic of Uzbekistan.
