A biosystematic study of Kamchatka taxa Elymus charkeviczii, E. subfibrosus and E. mutabilis in comparison with selected biotypes of E. kamczadalorum was carried out. The results of the electrophoretic analysis of en-dosperm storage proteins and hybridological analysis of distinctive morphological characters support the previous conclusion that E. charkeviczii, E. subfibrosus and E. mutabilis on Kamchatka are just morphological variants of the same taxon, which probably is endemic to Kamchatka and should be named E. charkeviczii s.l. E. kamczadalorum is a distinct species although introgression may occur between this species and E. charkeviczii at places where the two species grow together.
