Notes.

Aipeisova (2012, 2013) reported D. majalis . for Mugodzhary (near Ber-Chogur and Mount Boktybai). Although corresponding herbarium specimens were not located, we believe that this report is an obvious mistake. It is more likely that the plants were D. umbrosa , as we found herbarium materials collected from the same place (near Ber-Chogur, 10 Jun 1927, Rusanov s.n. (AA!)). We consider D. umbrosa and D. salina to be closely-related species and determining plants with certainty can sometimes be challenging.
