Natural Populations of the Rare Medicinal Species Alangium platanifolium (Alangiacеае) in Russia.

Data on the status of two natural populations of the rare, endemic medicinal species Alangium platanifolium known from the Russian Federation is provided in this article. Information about one of them is reported for the first time. Geobotanical descriptions of the phytocenoses are presented. In southern Primorskii krai, A. platanifolium has been noted to grow in the shrub layer of coniferous/broad-leaved forest with Pinus koraiensis and Abies holophylla. It has also been found that the area of the population discovered 20 years ago has expanded tenfold and now amounts to 10 ha. The new locality of A. platanifolium covers an area of 0.25 ha. The total number of A. platanifolium is more than 700 of various-age plants. The data obtained extends the current knowledge of the distribution and life state of A. platanifolium and indicates the fact of the growth of subtropical elements in phytocenoses of the Russian Federation.
