Narrowly linear-leaved plants have been referred to E. uralensis Fischer ex Link, and robust lanceolate-leaved plants to E. boissieriana (Woronow) Prokh., but these 'species' merely represent extreme states in the ± continuous variation of E. virgata. In Europe, E. virgata merges with E. esula L., and has been regarded there as a subspecies of the latter. Huet du Pavilion's record of E. esula from Erzurum, cited by Tchihatcheff (Asie Min. Bot. 1:163, 1860), is undoubtedly referable to E. virgata.
