The study presents preliminary data on monitoring of Rhododendron brachycarpum D. Don ex G. Don fil.,a rare species of the Kunashir island flora. Comparative morphological and molecular phylogenetic analyses were carriedout with samples of R. brachycarpum and R. fauriei Franch from the island of Kunashir, the Sikhote-Alin Nature Reserve,and Japan (Honshu and Hokkaido islands). R. brachycarpum and R. fauriei are species with fuzzy boundaries concerningsystematics. The internal transcribed spacers (ITS1-5.8S-ITS2) in nrDNA were chosen as molecular markers. Preliminaryresults support the consideration that R. fauriei and R. brachycarpum are two separate species.
