Far Eastern species of Euonymus L. (Celastraceae): Additional data on diagnostic characters and distribution

Abstract

A critical analysis of morphological characters with special focus on degree of variability for closely related taxa allowed to justify the boundaries between representatives of the Euonymus growing i the Russian Far East. Clear morphological characters for 11 species were found and a key for species identification in field conditions is suggested. The species status for E. maximowiczianus, E. × miniatus, E. pauciflorus, E. planipes, E. sacrosanctus and E. sieboldianus has been proved.
