Aim. The species Euphorbia valdevillosocarpa is listed in the Red Data Book of Ukraine (2009), where it has the category of protection "endangered". It also has scientificimportance as a Bessarabian endemic on the eastern border of the range. The said species had not been observed in the lower reaches of the Dniester-Tiligul interfluves before.Methods. The floraof the region was studied by means of the route method in 2018-2020.Results. Near village Budiachky, in the valley which connects train station «Kar-pove» (Odesa-Rozdilna) and village Egorovka (on the coast of the Hadzhibeiskyi estuary), new for Odessa region locality of Euphorbia valdevillosocarpa wasfound. The place is located on the west slope, which is in the main valley. Near the site there is an abandoned quarry for shell mining. Plants of Euphorbia valdevillosocarpa were found only on the slope of the northern exposure. 20 plants of E. valdevillosocarpa were found, for each there were from 10 to 35 stems. Apparently due to unfavorable weather conditions in the region in 2020 (drought) plants are significantlysmaller in size, compared to dry specimens of stems from the previous year (to 0.95-1.00 m). The main part of the stems is vegetative, only a third part of the plants have remnants of inflorescences. On 06.2020 some specimens had re-blooming on several stems.Conclusions. The study area does not belong to those that have environmental sig-nificance.Localities of the species in Odesa region are represented only in Tarutyn` district. Thus, the locality near v. Budiachky is the most eastern point in the region. Since sozophytes of different levels of protection are also noted here, it is necessary to create a protected area.
