This species in the Russian Federation grows only in the south of Primorsky Terrritory and is known from a few populations. Field studies were conducted by route-reconnaissance method during the growing season of 2019-2021 years. The description of the phytocenosis of the new locality, population size, age composition, and morphometric parameters is given. The population of P. sinensis was found in the vicinity of the village of Lazo (43°21'424" north, 133°54'145" east), at an altitude of 180 m above sea level, in the valley of the Kievka River. 44 vegetative specimens of P. sinensis were found on an area of 0.5 hectares, of which 5 plants were in a generative state. 4 adult dry bushes were found dead, with traces of fire damage. The average height of the bushes in the population is 2 m 40 cm, the diameter of the crown varies from 1.5 to 2 m, the diameter of the stems is 1-4 cm. The limiting factors threatening the population P. sinensis are economic activity and grassroots fires.
