Floristic and geographical distinctions between meadow steppes of the order Festucetalia valesiacae and true steppes of the order Helictotricho-Stipetalia in the South Urals were studied. The geographical differentiation of the communities of the orders is difficult due to the complexity of the relief and strong fragmentation of the steppes. The floristic differentiation is possible in the absence in Helictotricho-Stipetalia communities of a diagnostic combination of meadow steppe species represented by the alliance Festucion valesiacae.
