New populations of such a rare species as Trillium Komarov (Trillium komarovii (family Trilliaceae)) have been discovered in the south of the Russian Far East (Primorsky Krai). The phytocenotic and ecotopic description of six new localities of T. komarovii is given. For the first time, the discovery of this plant is indicated in the Chuguevsky district, which is 200 km north of the most common habitats of T. komarovii in the Primorsky Territory. Thus, it is shown that the range of this species is expanding in a northerly direction. It is established that T. komarovii is included in the forest floristic complex of broad-leaved and coniferous-broad-leaved forests and has a narrow ecological status - it grows on moist forest soils with a large litter layer. A very high risk of extinction of this species in nature has been identified, as evidenced by a few populations, with a small number of individuals in them, rarely exceeding ten specimens. The species is included in the Red Book of Primorsky Krai with the protection status "Under extinction".
