, this ecoregion supports flora found in both biomes. Grasses, more dominant in the north, include various Stipa
species (S. lessingiana, S. sareptana, S. kirghisorum and the endemic S. richterana) and tipchak (Festuca valesiaca). To the south, shrubs come to dominate, mainly Artemisia species (A. lerchena and A. lessingiana, A. gracilescens, A. sublessingiana, A. terrae albae semiarida and A. sublessingiana). Vegetation on the saline plains consists of Artemisia pauciflora, A. schrenkiana, A. nitrosa, Atriplex cana, Anabasis salsa, and Camphorosma monspeliaca.
