Phenotypic variation of Alnus fruticosa Rupr. s.l. was studied in 25 populations in the area of Asian Russia. Significant intra-and interpopulational variations of the characters of leaves and pistillate catkins were revealed. It has been established that all alder forms growing in the area of Asian Russia, earlier classified as independent species, should belong to the species Alnus fruticosa.
