Abstract
The study of microevolution relationships between morphologically close species E. kamczadalorum (Nevski) Tzvelev, E. charkeviczii Probat., and E. kronokensis (Kom.) Tzvelev from Russian Far East was carried out by ISSR-method. The results confirmed the previously obtained data that Kamchatic endemic species E. kamczadalorum is genetically isolated from the complex E. charkeviczii s. l. The latter includes morphotypes with different degrees of expression in diagnostic characters (rachilla’s and lemma’s trichomes). It is widely distributed not only on the Kamchatka Peninsula, but also in continental areas of the Magadan region and, probably, the Republic Sakha (Yakutia). Th e species E. kronokensis which is similar in morphology to E. charkeviczii s. str., but distinctly separated from the latter on ISSR-markers.
